5 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.

9 Barber, John
[br]baptized 22 October 1734 Greasley, Nottinghamshire, Englandd. 6 November 1801 Attleborough, Nuneaton, England[br]English inventor of the gas turbine and jet propulsion.[br]He was the son of Francis Barber, coalmaster of Greasley, and Elizabeth Fletcher. In his will of 1765. his uncle, John Fletcher, left the bulk of his property, including collieries and Stainsby House, Horsley Woodhouse, Derbyshire, to John Barber. Another uncle, Robert, bequeathed him property in the next village, Smalley. It is clear that at this time John Barber was a man of considerable means. On a tablet erected by John in 1767, he acknowledges his debt to his uncle John in the words "in remembrance of the man who trained him up from a youth". At this time John Barber was living at Stainsby House and had already been granted his first patent, in 1766. The contents of this patent, which included a reversible water turbine, and his subsequent patents, suggest that he was very familiar with mining equipment, including the Newcomen engine. It comes as rather a surprise that c.1784 he became bankrupt and had to leave Stainsby House, evidently moving to Attleborough. In a strange twist, a descendent of Mr Sitwell, the new owner, bought the prototype Akroyd Stuart oil engine from the Doncaster Show in 1891.The second and fifth (final) patents, in 1773 and 1792, were concerned with smelting and the third, in 1776, featured a boiler-mounted impulse steam turbine. The fourth and most important patent, in 1791, describes and engine that could be applied to the "grinding of corn, flints, etc.", "rolling, slitting, forging or battering iron and other metals", "turning of mills for spinning", "turning up coals and other minerals from mines", and "stamping of ores, raising water". Further, and importantly, the directing of the fluid stream into smelting furnaces or at the stern of ships to propel them is mentioned. The engine described comprised two retorts for heating coal or oil to produce an inflammable gas, one to operate while the other was cleansed and recharged. The resultant gas, together with the right amount of air, passed to a beam-operated pump and a water-cooled combustion chamber, and then to a water-cooled nozzle to an impulse gas turbine, which drove the pumps and provided the output. A clear description of the thermodynamic sequence known as the Joule Cycle (Brayton in the USA) is thus given. Further, the method of gas production predates Murdoch's lighting of the Soho foundry by gas.It seems unlikely that John Barber was able to get his engine to work; indeed, it was well over a hundred years before a continuous combustion chamber was achieved. However, the details of the specification, for example the use of cooling water jackets and injection, suggest that considerable experimentation had taken place.To be active in the taking out of patents over a period of 26 years is remarkable; that the best came after bankruptcy is more so. There is nothing to suggest that the cost of his experiments was the cause of his financial troubles.[br]Further ReadingA.K.Bruce, 1944, "John Barber and the gas turbine", Engineer 29 December: 506–8; 8 March (1946):216, 217.C.Lyle Cummins, 1976, Internal Fire, Carnot Press.JB -
10 Caprotti, Arturo
[br]b. 22 March 1881 Cremona, Italyd. 9 February 1938 Milan, Italy[br]Italian engineer, inventor of Caprotti poppet valve gear for steam locomotives.[br]Caprotti graduated as a mechanical engineer at Turin Royal Polytechnic College and spent some years in the motor car industry. After researching the application of poppet valves to railway locomotives, he invented his rotary cam valve gear for poppet valves in 1915. Compared with usual slide and piston valves and valve gears, it offered independent timing of inlet and exhaust valves and a saving in weight. Valve gear to Caprotti's design was first fitted in 1920 to a 2−6−0 locomotive of the Italian State Railways, and was subsequently widely used there and elsewhere. Caprotti valve gear was first applied in Britain in 1926 to a Claughton class 4−6−0 of the London, Midland \& Scottish Railway, resulting in substantial fuel savings compared with a similar locomotive fitted with Walschaert's valve gear and piston valves. Others of the class were then fitted similarly. Caprotti valve gear never came into general use in Britain and its final application was in 1954 to British Railways class 8 4−6−2 no. 71000; this was intended as the prototype of a class of standard locomotives for express trains, but the class was never built, because diesel and electric locomotives took their place. Some components survived scrapping, and a reconstruction of the locomotive is in working order.[br]Further ReadingJohn Marshall, 1978, A Biographical Dictionary of Railway Engineers, Newton Abbot: David \& Charles.P.Ransome-Wallis (ed.), 1959, The Concise Encyclopaedia of World Railway Locomotives, London: Hutchinson (contains a note about Caprotti (p. 497) and a description of the valve gear (p. 301).PJGR -
11 Rateau, Auguste Camille-Edmond
[br]b. 13 October 1863 Royan, Franced. 13 January 1930 Neuilly-sur-Seine, France[br]French constructor of turbines, inventor of the turbo compressor and a centrifugal fan for mine ventilation.[br]A don of the Ecole Polytechnique and the Ecole Supérieure des Mines in Paris, Rateau joined the French Corps des Mines in 1887. Between 1888 and 1898 he taught applied mechanics and electro technics at the Ecole des Mines in St-Etienne. Trying to apply the results of his research to practise, he became into contact with commercial firms, before he was appointed Professor of Industrial Electricity at the Ecole Supérieure des Mines in Paris in 1902. He held this position until 1910, although he founded the Société Anonyme Rateau in Paris in 1903 which by the time of his death had subsidiaries in most of the industrial centres of Europe. By the middle of the nineteenth century, when the increasing problems of ventilation in coal mines had become evident and in many countries had led to several unsatisfactory mechanical constructions, Rateau concentrated on this problem soon after he began working in St-Etienne. The result of his research was the design of a centrifugal fan in 1887 with which he established the principles of mechanical ventilation on a general basis that led to future developments and helped, together with the ventilator invented by Capell in England, to pave the way for the use of electricity in mine ventilation.Rateau continued the study of fluid mechanics and the applications of rotating engines, and after he had published widely on this subject he began to construct many steam turbines, centrifugal compressors and centrifugal pumps. The multicellular Rateau turbine of 1901 became the prototype for many others constructors. During the First World War, when he was very active in the French armaments industry, he developed the invention of the automatic supercharger for aircraft engines and later diesel engines.[br]Principal Honours and DistinctionsAcadémie des Sciences, Prix Fourneyron 1899, Prix Poncelet 1911, Member 1918.Bibliography1892, Considérations sur les turbo-machines et en particulier sur les ventilateurs, St- Etienne.1900, Traité des turbo-machines, Paris.1907, Ventilateurs centrifuges à haute pression, Paris.1908.

12 Séguin, Louis
[br]b. 1869d. 1918[br]French co-designer, with his brother Laurent Séguin (b. 1883 Rhône, France; d. 1944), of the extremely successful Gnome rotary engines.[br]Most early aero-engines were adaptations of automobile engines, but Louis Séguin and his brother Laurent set out to produce a genuine aero-engine. They decided to build a "rotary" engine in which the crankshaft remained stationary and the cylinders rotated: the propeller was attached to the cylinders. The idea was not new, for rotary engines had been proposed by engineers from James Watt to Samuel P. Langley, rival of the Wright brothers. (An engine with stationary cylinders and a rotating crankshaftplus-propeller is classed as a "radial".) Louis Séguin formed the Société des Moteurs Gnome in 1906 to build stationary industrial engines. Laurent joined him to develop a lightweight engine specifically for aeronautical use. They built a fivecylinder air-cooled radial engine in 1908 and then a prototype seven-cylinder rotary engine. Later in the year the Gnome Oméga rotary, developing 50 hp (37 kW), was produced. This was test-flown in a Voisin biplane during June 1909. The Gnome was much lighter than its conventional rivals and surprisingly reliable in view of the technical problems of supplying rotating cylinders with the petrol-air mixture and a spark to ignite it. It was an instant success.Gnomes were mass-produced for use during the First World War. Both sides built and flew rotary engines, which were improved over the years until, by 1917, their size had grown to such an extent that a further increase was not practicable. The gyroscopic effects of a large rotating engine became a serious handicap to manoeuvrability, and the technical problems inherent in a rotary engine were accentuated.[br]Bibliography1912, L'Aérophile 20(4) (Louis Séguin's description of the Gnome).Further ReadingC.F.Taylor, 1971, "Aircraft Propulsion", Smithsonian Annals of Flight 1(4) (an account of the evolution of aircraft piston engines).A.Nahum, 1987, the Rotary Aero-Engine, London.JDS -
13 Westinghouse, George
[br]b. 6 October 1846 Central Bridge, New York, USAd. 12 March 1914 New York, New York, USA[br]American inventor and entrepreneur, pioneer of air brakes for railways and alternating-current distribution of electricity.[br]George Westinghouse's father was an ingenious manufacturer of agricultural implements; the son, after a spell in the Union Army during the Civil War, and subsequently in the Navy as an engineer, went to work for his father. He invented a rotary steam engine, which proved impracticable; a rerailing device for railway rolling stock in 1865; and a cast-steel frog for railway points, with longer life than the cast-iron frogs then used, in 1868–9. During the same period Westinghouse, like many other inventors, was considering how best to meet the evident need for a continuous brake for trains, i.e. one by which the driver could apply the brakes on all vehicles in a train simultaneously instead of relying on brakesmen on individual vehicles. By chance he encountered a magazine article about the construction of the Mont Cenis Tunnel, with a description of the pneumatic tools invented for it, and from this it occurred to him that compressed air might be used to operate the brakes along a train.The first prototype was ready in 1869 and the Westinghouse Air Brake Company was set up to manufacture it. However, despite impressive demonstration of the brake's powers when it saved the test train from otherwise certain collision with a horse-drawn dray on a level crossing, railways were at first slow to adopt it. Then in 1872 Westinghouse added to it the triple valve, which enabled the train pipe to charge reservoirs beneath each vehicle, from which the compressed air would apply the brakes when pressure in the train pipe was reduced. This meant that the brake was now automatic: if a train became divided, the brakes on both parts would be applied. From then on, more and more American railways adopted the Westinghouse brake and the Railroad Safety Appliance Act of 1893 made air brakes compulsory in the USA. Air brakes were also adopted in most other parts of the world, although only a minority of British railway companies took them up, the remainder, with insular reluctance, preferring the less effective vacuum brake.From 1880 Westinghouse was purchasing patents relating to means of interlocking railway signals and points; he combined them with his own inventions to produce a complete signalling system. The first really practical power signalling scheme, installed in the USA by Westinghouse in 1884, was operated pneumatically, but the development of railway signalling required an awareness of the powers of electricity, and it was probably this that first led Westinghouse to become interested in electrical processes and inventions. The Westinghouse Electric Company was formed in 1886: it pioneered the use of electricity distribution systems using high-voltage single-phase alternating current, which it developed from European practice. Initially this was violently opposed by established operators of direct-current distribution systems, but eventually the use of alternating current became widespread.[br]Principal Honours and DistinctionsLégion d'honneur.

15 Memory
To what extent can we lump together what goes on when you try to recall: (1) your name; (2) how you kick a football; and (3) the present location of your car keys? If we use introspective evidence as a guide, the first seems an immediate automatic response. The second may require constructive internal replay prior to our being able to produce a verbal description. The third... quite likely involves complex operational responses under the control of some general strategy system. Is any unitary search process, with a single set of characteristics and inputoutput relations, likely to cover all these cases? (Reitman, 1970, p. 485)[Semantic memory] Is a mental thesaurus, organized knowledge a person possesses about words and other verbal symbols, their meanings and referents, about relations among them, and about rules, formulas, and algorithms for the manipulation of these symbols, concepts, and relations. Semantic memory does not register perceptible properties of inputs, but rather cognitive referents of input signals. (Tulving, 1972, p. 386)The mnemonic code, far from being fixed and unchangeable, is structured and restructured along with general development. Such a restructuring of the code takes place in close dependence on the schemes of intelligence. The clearest indication of this is the observation of different types of memory organisation in accordance with the age level of a child so that a longer interval of retention without any new presentation, far from causing a deterioration of memory, may actually improve it. (Piaget & Inhelder, 1973, p. 36)4) The Logic of Some Memory Theorization Is of Dubious Worth in the History of PsychologyIf a cue was effective in memory retrieval, then one could infer it was encoded; if a cue was not effective, then it was not encoded. The logic of this theorization is "heads I win, tails you lose" and is of dubious worth in the history of psychology. We might ask how long scientists will puzzle over questions with no answers. (Solso, 1974, p. 28)We have iconic, echoic, active, working, acoustic, articulatory, primary, secondary, episodic, semantic, short-term, intermediate-term, and longterm memories, and these memories contain tags, traces, images, attributes, markers, concepts, cognitive maps, natural-language mediators, kernel sentences, relational rules, nodes, associations, propositions, higher-order memory units, and features. (Eysenck, 1977, p. 4)The problem with the memory metaphor is that storage and retrieval of traces only deals [ sic] with old, previously articulated information. Memory traces can perhaps provide a basis for dealing with the "sameness" of the present experience with previous experiences, but the memory metaphor has no mechanisms for dealing with novel information. (Bransford, McCarrell, Franks & Nitsch, 1977, p. 434)7) The Results of a Hundred Years of the Psychological Study of Memory Are Somewhat DiscouragingThe results of a hundred years of the psychological study of memory are somewhat discouraging. We have established firm empirical generalisations, but most of them are so obvious that every ten-year-old knows them anyway. We have made discoveries, but they are only marginally about memory; in many cases we don't know what to do with them, and wear them out with endless experimental variations. We have an intellectually impressive group of theories, but history offers little confidence that they will provide any meaningful insight into natural behavior. (Neisser, 1978, pp. 12-13)A schema, then is a data structure for representing the generic concepts stored in memory. There are schemata representing our knowledge about all concepts; those underlying objects, situations, events, sequences of events, actions and sequences of actions. A schema contains, as part of its specification, the network of interrelations that is believed to normally hold among the constituents of the concept in question. A schema theory embodies a prototype theory of meaning. That is, inasmuch as a schema underlying a concept stored in memory corresponds to the mean ing of that concept, meanings are encoded in terms of the typical or normal situations or events that instantiate that concept. (Rumelhart, 1980, p. 34)Memory appears to be constrained by a structure, a "syntax," perhaps at quite a low level, but it is free to be variable, deviant, even erratic at a higher level....Like the information system of language, memory can be explained in part by the abstract rules which underlie it, but only in part. The rules provide a basic competence, but they do not fully determine performance. (Campbell, 1982, pp. 228, 229)When people think about the mind, they often liken it to a physical space, with memories and ideas as objects contained within that space. Thus, we speak of ideas being in the dark corners or dim recesses of our minds, and of holding ideas in mind. Ideas may be in the front or back of our minds, or they may be difficult to grasp. With respect to the processes involved in memory, we talk about storing memories, of searching or looking for lost memories, and sometimes of finding them. An examination of common parlance, therefore, suggests that there is general adherence to what might be called the spatial metaphor. The basic assumptions of this metaphor are that memories are treated as objects stored in specific locations within the mind, and the retrieval process involves a search through the mind in order to find specific memories....However, while the spatial metaphor has shown extraordinary longevity, there have been some interesting changes over time in the precise form of analogy used. In particular, technological advances have influenced theoretical conceptualisations.... The original Greek analogies were based on wax tablets and aviaries; these were superseded by analogies involving switchboards, gramophones, tape recorders, libraries, conveyor belts, and underground maps. Most recently, the workings of human memory have been compared to computer functioning... and it has been suggested that the various memory stores found in computers have their counterparts in the human memory system. (Eysenck, 1984, pp. 79-80)Primary memory [as proposed by William James] relates to information that remains in consciousness after it has been perceived, and thus forms part of the psychological present, whereas secondary memory contains information about events that have left consciousness, and are therefore part of the psychological past. (Eysenck, 1984, p. 86)Once psychologists began to study long-term memory per se, they realized it may be divided into two main categories.... Semantic memories have to do with our general knowledge about the working of the world. We know what cars do, what stoves do, what the laws of gravity are, and so on. Episodic memories are largely events that took place at a time and place in our personal history. Remembering specific events about our own actions, about our family, and about our individual past falls into this category. With amnesia or in aging, what dims... is our personal episodic memories, save for those that are especially dear or painful to us. Our knowledge of how the world works remains pretty much intact. (Gazzaniga, 1988, p. 42)The nature of memory... provides a natural starting point for an analysis of thinking. Memory is the repository of many of the beliefs and representations that enter into thinking, and the retrievability of these representations can limit the quality of our thought.
