16 capacity ratios
Finmeasures of performance in the use of capacity.EXAMPLEThe more commonly used capacity levels are: full capacity—output (expressed in standard hours) that could be achieved if sales orders, supplies, and workforce were available for all installed workplaces; practical capacity—full capacity less an allowance for known unavoidable volume losses; budgeted capacity—standard hours planned for the period, taking into account budgeted sales, supplies, workforce availability, and efficiency expected; normal capacity.On the following given data, the related ratios are set out below:.jpg)
Idle capacity ratio is calculated as follows:(Practical capacity – budgeted capacity) × 100/Practical capacity = (95 – 81) × 100/95 = 15%, indicates the budgeted shortfall in capacity as a proportion of practical capacity. -

18 Curr, John
[br]b. 1756 Kyo, near Lanchester, or in Greenside, near Ryton-on-Tyne, Durham, Englandd. 27 January 1823 Sheffield, England[br]English coal-mine manager and engineer, inventor of flanged, cast-iron plate rails.[br]The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.[br]Bibliography1788. British patent no. 1,660 (guides in mine shafts).1789.

19 Gramme, Zénobe Théophile
[br]b. 4 April 1826 Jehay-Bodignée, Belgiumd. 20 January 1901 Bois de Colombes, Paris, France[br]Belgian engineer whose improvements to the dynamo produced a machine ready for successful commercial exploitation.[br]Gramme trained as a carpenter and showed an early talent for working with machinery. Moving to Paris he found employment in the Alliance factory as a model maker. With a growing interest in electricity he left to become an instrument maker with Heinrich Daniel Rühmkorff. In 1870 he patented the uniformly wound ring-armature dynamo with which his name is associated. Together with Hippolyte Fontaine, in 1871 Gramme opened a factory to manufacture his dynamos. They rapidly became a commercial success for both arc lighting and electrochemical purposes, international publicity being achieved at exhibitions in Vienna, Paris and Philadelphia. It was the realization that a Gramme machine was capable of running as a motor, i.e. the reversibility of function, that illustrated the entire concept of power transmission by electricity. This was first publicly demonstrated in 1873. In 1874 Gramme reduced the size and increased the efficiency of his generators by relying completely on the principle of self-excitation. It was the first practical machine in which were combined the features of continuity of commutation, self-excitation, good lamination of the armature core and a reasonably good magnetic circuit. This dynamo, together with the self-regulating arc lamps then available, made possible the innumerable electric-lighting schemes that followed. These were of the greatest importance in demonstrating that electric lighting was a practical and economic means of illumination. Gramme also designed an alternator to operate Jablochkoff candles. For some years he took an active part in the operations of the Société Gramme and also experimented in his own workshop without collaboration, but made no further contribution to electrical technology.[br]Principal Honours and DistinctionsKnight Commander, Order of Leopold of Belgium 1897.

20 Tainter, Charles Sumner
SUBJECT AREA: Recording[br]b. 1854d. 1940[br]American scientific instrument maker, co-developer of practical cylinder recording.[br]He manufactured "philosophical devices" in Cambridge, Massachusetts, and was approached by Alexander Graham Bell in connection with the construction of toys using sound recordings. A more formal co-operation was agreed, and after Bell's receipt of the French Volta prize in 1880 he financed the Volta Laboratory Association in Washington, DC. He founded this in 1881 together with a cousin and Tainter to develop a practical sound-recording and -reproducing system. Another area that was developed was the transmission of sound by means of modulated light and reception via a selenium cell.The advances in sound recording and reproduction were very positive, and T.A. Edison was approached in mid-1885 in order to establish co-operation in the further development of a cylinder instrument. In early 1886 the Volta Graphophone Company was incorporated in Virginia, and an experimental laboratory was established in Washington, DC. The investors were connected with the secretarial services at the House of Representatives and needed the development for increasing efficiency in debate reporting. In mid-1887 Edison, against the advice of his collaborators, declined co-operation and went ahead on his own. There is no doubt that Tainter's skill in developing functional equipment and the speed with which he was able to work in the crucial years provoked other developments in the field, in particular the perfection of the Edison phonograph and the development of the disc record by Berliner.[br]BibliographyTainter's patents were numerous; those on sound recording were the most important, because they incorporated so many fundamental ideas, and included US patent no. 341, 214 (with C.A.Bell), and US patent no. 375, 579 (a complete dictation outfit).Further ReadingV.K.Chew, 1981, Talking Machines, London: Science Museum and HMSO, pp. 9–12 (provides a good overview, not only of Tainter's contribution, but also of early sound recording and reproduction).GB-NBiographical history of technology > Tainter, Charles Sumner
