  • 12 Smalley, John

    SUBJECT AREA: Textiles
    [br]
    b. c. 1729 England
    d. 28 January 1782 Holywell, Wales.
    [br]
    English helped Arkwright to build and finance the waterframe.
    [br]
    John Smalley of Preston was the second son of John, a chapman of Blackburn. He was a distant relative of Richard Arkwright through marrying, in 1751, Elizabeth Baxter, whose mother Ellen was the widow of Arkwright's uncle, Richard. In the Preston Guild Rolls of 1762 he was described as a grocer and painter, and he was also Landlord of the Bull Inn. The following year he became a bailiff of Preston and in 1765 he became a Corporation steward. On 14 May 1768 Arkwright, Smalley and David Thornley became partners in a cotton-spinning venture in Nottingham. They agreed to apply for a patent for Arkwright's invention of spinning by rollers, and Smalley signed as a witness. It is said that Smalley provided much of the capital for this new venture as he sold his business at Preston for about £1,600, but this was soon found to be insufficient and the partnership had to be enlarged to include Samuel Need and Jedediah Strutt.
    Smalley may have helped to establish the spinning mill at Nottingham, but by 28 February 1771 he was back in Preston, for on that day he was chosen a "Councilman in the room of Mr. Thomas Jackson deceased" (Fitton 1989:38). He attended meetings for over a year, but either in 1772 or the following year he sold the Bull Inn, and certainly by August 1774 the Smalleys were living in Cromford, where he became Manager of the mill. He soon found himself at logger-heads with Arkwright; however, Strutt was able to smooth the dispute over for a while. Things came to a head in January 1777 when Arkwright was determined to get rid of Smalley, and the three remaining partners agreed to buy out Smalley's share for the sum of £10,751.
    Although he had agreed not to set up any textile machinery, Smalley moved to Holywell in North Wales, where in the spring of 1777 he built a cotton-spinning mill in the Greenfield valley. He prospered there and his son was later to build two more mills in the same valley. Smalley used to go to Wrexham to sell his yarn, and there met John Peers, a leather merchant, who was able to provide a better quality leather for covering the drawing rollers which came to be used in Lancashire. Smalley died in 1782, shortly before Arkwright could sue him for infringement of his patents.

  • 13 Barnack, Oskar

    [br]
    b. 1879 Berlin, Germany
    d. January 1936 Wetzlar, Germany
    [br]
    German camera designer who conceived the first Leica camera and many subsequent models.
    [br]
    Oskar Barnack was an optical engineer, introspective and in poor health, when in 1910 he was invited through the good offices of his friend the mechanical engineer Emil Mechau, who worked for Ernst Leitz, to join the company at Wetzlar to work on research into microscope design. He was engaged after a week's trial, and on 2 January 1911 he was put in charge of microscope research. He was an enthusiastic photographer, but excursions with his large and heavy plate camera equipment taxed his strength. In 1912, Mechau was working on a revolutionary film projector design and needed film to test it. Barnack suggested that it was not necessary to buy an expensive commercial machine— why not make one? Leitz agreed, and Barnack constructed a 35 mm movie camera, which he used to cover events in and around Wetzlar.
    The exposure problems he encountered with the variable sensitivity of the cine film led him to consider the design of a still camera in which short lengths of film could be tested before shooting—a kind of exposure-meter camera. Dissatisfied with the poor picture quality of his first model, which took the standard cine frame of 18×24 mm, he built a new model in which the frame size was doubled to 36×24 mm. It used a simple focal-plane shutter adjustable to 1/500 of a second, and a Zeiss Milar lens of 42 mm focal length. This is what is now known as the UR-Leica. Using his new camera, 1/250 of the weight of his plate equipment, Barnack made many photographs around Wetzlar, giving postcard-sized prints of good quality.
    Ernst Leitz Junior was lent the camera for his trip in June 1914 to America, where he was urged to put it into production. Visiting George Eastman in Rochester, Leitz passed on Barnack's requests for film of finer grain and better quality. The First World War put an end to the chances of developing the design at that time. As Germany emerged from the postwar chaos, Leitz Junior, then in charge of the firm, took Barnack off microscope work to design prototypes for a commercial model. Leitz's Chief Optician, Max Berek, designed a new lens, the f3.5 Elmax, for the new camera. They settled on the name Leica, and the first production models went on show at the Leipzig Spring Fair in 1925. By the end of the year, 1,000 cameras had been shipped, despite costing about two months' good wages.
    The Leica camera established 35 mm still photography as a practical proposition, and film manufacturers began to create the special fine-grain films that Barnack had longed for. He continued to improve the design, and a succession of new Leica models appeared with new features, such as interchangeable lenses, coupled range-finders, 250 exposures. By the time of his sudden death in 1936, Barnack's life's work had forever transformed the nature of photography.

    SUBJECT AREA: Ports and shipping
    [br]
    b. 1767 Torphichen Mill, near Linlithgow, Scotland
    d. 1830 Helensburgh, Scotland
    [br]
    Scottish projector of the first steamboat service in Europe.
    [br]
    The son of Patrick Bell, a millwright, Henry had two sisters and an elder brother and was educated at the village school. When he was 9 years old Henry was sent to lodge in Falkirk with an uncle and aunt of his mother's so that he could attend the school there. At the age of 12 he left school and agreed to become a mason with a relative. In 1783, after only three years, he was bound apprentice to his Uncle Henry, a millwright at Jay Mill. He stayed there for a further three years and then, in 1786, joined the firm of Shaw \& Hart, shipbuilders of Borrowstoneness. These were to be the builders of William Symington's hull for the Charlotte Dundas. He also spent twelve months with Mr James Inglis, an engineer of Bellshill, Lanarkshire, and then went to London to gain experience, working for the famous John Rennie for some eighteen months. By 1790 he was back in Glasgow, and a year later he took a partner, James Paterson, into his new business of builder and contractor, based in the Trongate. He later referred to himself as "architect", and his partnership with Paterson lasted seven years. He is said to have invented a discharging machine for calico printing, as well as a steam dredger for clearing the River Clyde.
    The Baths Hotel was opened in Helensburgh in 1808, with the hotel-keeper, who was also the first provost of the town, being none other than Henry Bell. It has been suggested that Bell was also the builder of the hotel and this seems very likely. Bell installed a steam engine for pumping sea water out of the Clyde and into the baths, and at first ran a coach service to bring customers from Glasgow three days a week. The driver was his brother Tom. The coach was replaced by the Comet steamboat in 1812.
    While Henry was busy with his provost's duties and making arrangements for the building of his steamboat, his wife Margaret, née Young, whom he married in March 1794, occupied herself with the management of the Baths Hotel. Bell did not himself manufacture, but supervised the work of experts: John and Charles Wood of Port Glasgow, builders of the 43ft 6 in. (13.25 m)-long hull of the Comet; David Napier of Howard Street Foundry for the boiler and other castings; and John Robertson of Dempster Street, who had previously supplied a small engine for pumping water to the baths at the hotel in Helensburgh, for the 3 hp engine. The first trials of the finished ship were held on 24 July 1812, when she was launched from Wood's yard. A regular service was advertised in the Glasgow Chronicle on 5 August and was the first in Europe, preceded only by that of Robert Fulton in the USA. The Comet continued to run until 1820, when it was wrecked.
    Bell received little reward for his promotion of steam navigation, merely small pensions from the Clyde trustees and others. He was buried at the parish church of Rhu.

  • 15 Bourn, Daniel

    SUBJECT AREA: Textiles
    [br]
    fl. 1744 Lancashire, England
    [br]
    English inventor of a machine with cylinders for carding cotton.
    [br]
    Daniel Bourn may well have been a native of Lancashire. He set up a fourth Paul-Wyatt cotton-spinning mill at Leominster, Herefordshire, possibly in 1744, although the earliest mention of it is in 1748. His only known partner in this mill was Henry Morris, a yarn dealer who in 1743 had bought a grant of spindles from Paul at the low rate of 30 shillings or 40 shillings per spindle when the current price was £3 or £4. When Bourn patented his carding engine in 1748, he asked Wyatt for a grant of spindles, to which Wyatt agreed because £100 was offered immedi-ately. The mill, which was probably the only one outside the control of Paul and his backers, was destroyed by fire in 1754 and was not rebuilt, although Bourn and his partners had considerable hopes for it. Bourn was said to have lost over £1,600 in the venture.
    Daniel Bourn described himself as a wool and cotton dealer of Leominster in his patent of 1748 for his carding engine. The significance of this invention is the use of rotating cylinders covered with wire clothing. The patent drawing shows four cylinders, one following the other to tease out the wool, but Bourn was unable to discover a satisfactory method of removing the fibres from the last cylinder. It is possible that Robert Peel in Lancashire obtained one of these engines through Morris, and that James Hargreaves tried to improve it; if so, then some of the early carding engines in the cotton industry were derived from Bourn's.

    [br]
    b. mid-twentieth century
    [br]
    English inventor who developed a new design of racing bicycle.
    [br]
    His father was a pattern-maker who worked for a time at the de Havilland aircraft factory at Hatfield, Hertfordshire; later he worked in an aeroplane-model shop before turning his attentions to boats and cars. Mike Burroughs left school at the age of 15 to become a self-taught engineer and inventor, regarding himself as an eccentric. Among other things, he invented a machine for packaging coins.
    In the 1970s he began to take an interest in bicycles, and he subjected the design and materials of existing machines of conventional design to searching reappraisal. As a result, Burroughs "reinvented" the bicycle, producing an entirely new concept. His father carved the shape of the single-piece frame in wood, from which a carbon-fibre cast was made. The machine proved to be very fast, but neither the sporting nor the industrial world showed much interest in it. Then in 1991 Rudi Terman, of the motor manufacturers Lotus, saw it and was impressed by its potential; he agreed to develop the machine further, but kept the details secret.
    The invention was released to an unsuspecting public at the Barcelona Olympic Games of 1992, ridden by Chris Boardman, who won the pursuit gold medal for Great Britain, a triumph for both rider and inventor. In subsequent months, Boardman went on to break several world records on the Lotus bicycle, including on 23 July 1993 the one-hour record with a distance of 52.27 km (32.48 miles).

    [br]
    bapt. 13 June 1779 Great Asby, Westmoreland, England
    d. 28 February 1844 London, England
    [br]
    English machine tool builder and inventor.
    [br]
    Although known as Clement in his professional life, his baptism at Asby and his death were registered under the name of Joseph Clemmet. He worked as a slater until the age of 23, but his interest in mechanics led him to spend much of his spare time in the local blacksmith's shop. By studying books on mechanics borrowed from his cousin, a watchmaker, he taught himself and with the aid of the village blacksmith made his own lathe. By 1805 he was able to give up the slating trade and find employment as a mechanic in a small factory at Kirkby Stephen. From there he moved to Carlisle for two years, and then to Glasgow where, while working as a turner, he took lessons in drawing; he had a natural talent and soon became an expert draughtsman. From about 1809 he was employed by Leys, Mason \& Co. of Aberdeen designing and making power looms. For this work he built a screw-cutting lathe and continued his self-education. At the end of 1813, having saved about £100, he made his way to London, where he soon found employment as a mechanic and draughtsman. Within a few months he was engaged by Joseph Bramah, and after a trial period a formal agreement dated 1 April 1814 was made by which Clement was to be Chief Draughtsman and Superintendent of Bramah's Pimlico works for five years. However, Bramah died in December 1814 and after his sons took over the business it was agreed that Clement should leave before the expiry of the five-year period. He soon found employment as Chief Draughtsman with Henry Maudslay \& Co. By 1817 Clement had saved about £500, which enabled him to establish his own business at Prospect Place, Newington Butts, as a mechanical draughtsman and manufacturer of high-class machinery. For this purpose he built lathes for his own use and invented various improvements in their detailed design. In 1827 he designed and built a facing lathe which incorporated an ingenious system of infinitely variable belt gearing. He had also built his own planing machine by 1820 and another, much larger one in 1825. In 1828 Clement began making fluted taps and dies and standardized the screw threads, thus anticipating on a small scale the national standards later established by Sir Joseph Whitworth. Because of his reputation for first-class workmanship, Clement was in the 1820s engaged by Charles Babbage to carry out the construction of his first Difference Engine.

  • 18 Corliss, George Henry

    [br]
    b. 2 June 1817 Easton, Washington City, New York, USA
    d. 21 February 1888 USA
    [br]
    American inventor of a cut-off mechanism linked to the governor which revolutionized the operation of steam engines.
    [br]
    Corliss's father was a physician and surgeon. The son was educated at Greenwich, New York, but while he showed an aptitude for mathematics and mechanics he first of all became a storekeeper and then clerk, bookkeeper, salesperson and official measurer and inspector of the cloth produced at W.Mowbray \& Son. He went to the Castleton Academy, Vermont, for three years and at the age of 21 returned to a store of his own in Greenwich. Complaints about stitching in the boots he sold led him to patent a sewing machine. He approached Fairbanks, Bancroft \& Co., Providence, Rhode Island, machine and steam engine builders, about producing his machine, but they agreed to take him on as a draughtsman providing he abandoned it. Corliss moved to Providence with his family and soon revolutionized the design and construction of steam engines. Although he started working out ideas for his engine in 1846 and completed one in 1848 for the Providence Dyeing, Bleaching and Calendering Company, it was not until March 1849 that he obtained a patent. By that time he had joined John Barstow and E.J.Nightingale to form a new company, Corliss Nightingale \& Co., to build his design of steam-engines. He used paired valves, two inlet and two exhaust, placed on opposite sides of the cylinder, which gave good thermal properties in the flow of steam. His wrist-plate operating mechanism gave quick opening and his trip mechanism allowed the governor to regulate the closure of the inlet valve, giving maximum expansion for any load. It has been claimed that Corliss should rank equally with James Watt in the development of the steam-engine. The new company bought land in Providence for a factory which was completed in 1856 when the Corliss Engine Company was incorporated. Corliss directed the business activities as well as technical improvements. He took out further patents modifying his valve gear in 1851, 1852, 1859, 1867, 1875, 1880. The business grew until well over 1,000 workers were employed. The cylindrical oscillating valve normally associated with the Corliss engine did not make its appearance until 1850 and was included in the 1859 patent. The impressive beam engine designed for the 1876 Centennial Exhibition by E. Reynolds was the product of Corliss's works. Corliss also patented gear-cutting machines, boilers, condensing apparatus and a pumping engine for waterworks. While having little interest in politics, he represented North Providence in the General Assembly of Rhode Island between 1868 and 1870.

  • 19 Edison, Thomas Alva

    [br]
    b. 11 February 1847 Milan, Ohio, USA
    d. 18 October 1931 Glenmont
    [br]
    American inventor and pioneer electrical developer.
    [br]
    He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.
    At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.
    Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.
    He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.
    Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.
    Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.
    Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.
    In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.
    On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.
    Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.
    In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.
    In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.
    In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.
    In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.
    In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.

    [br]
    b. 1907 Vienna, Austria
    [br]
    Austrian engineer responsible for the invention of the printed circuit.
    [br]
    At the age of 23, Eisler obtained a Diploma in Engineering from the Technical University of Vienna. Because of the growing Nazi influence in Austria, he then accepted a post with the His Master's Voice (HMV) agents in Belgrade, where he worked on the problems of radio reception and sound transmission in railway trains. However, he soon returned to Vienna to found a weekly radio journal and file patents on graphical sound recording (for which he received a doctorate) and on a system of stereoscopic television based on lenticular vertical scanning.
    In 1936 he moved to England and sold the TV patent to Marconi for £250. Unable to find a job, he carried out experiments in his rooms in a Hampstead boarding-house; after making circuits using strip wires mounted on bakelite sheet, he filed his first printed-circuit patent that year. He then tried to find ways of printing the circuits, but without success. Obtaining a post with Odeon Theatres, he invented a sound-level control for films and devised a mirror-drum continuous-film projector, but with the outbreak of war in 1939, when the company was evacuated, he chose to stay in London and was interned for a while. Released in 1941, he began work with Henderson and Spalding, a firm of lithographic printers, to whom he unwittingly assigned all future patents for the paltry sum of £1. In due course he perfected a means of printing conducting circuits and on 3 February 1943 he filed three patents covering the process. The British Ministry of Defence rejected the idea, considering it of no use for military equipment, but after he had demonstrated the technique to American visitors it was enthusiastically taken up in the US for making proximity fuses, of which many millions were produced and used for the war effort. Subsequently the US Government ruled that all air-borne electronic circuits should be printed.
    In the late 1940s the Instrument Department of Henderson and Spalding was split off as Technograph Printed Circuits Ltd, with Eisler as Technical Director. In 1949 he filed a further patent covering a multilayer system; this was licensed to Pye and the Telegraph Condenser Company. A further refinement, patented in the 1950s, the use of the technique for telephone exchange equipment, but this was subsequently widely infringed and although he negotiated licences in the USA he found it difficult to license his ideas in Europe. In the UK he obtained finance from the National Research and Development Corporation, but they interfered and refused money for further development, and he eventually resigned from Technograph. Faced with litigation in the USA and open infringement in the UK, he found it difficult to establish his claims, but their validity was finally agreed by the Court of Appeal (1969) and the House of Lords (1971).
    As a freelance inventor he filed many other printed-circuit patents, including foil heating films and batteries. When his Patent Agents proved unwilling to fund the cost of filing and prosecuting Complete Specifications he set up his own company, Eisler Consultants Ltd, to promote food and space heating, including the use of heated cans and wallpaper! As Foil Heating Ltd he went into the production of heating films, the process subsequently being licensed to Thermal Technology Inc. in California.
