Title: Improvements in or relating to digital calculating apparatus
Inventor: DUKE KEITH ALBERT
IPC: G06F7/50
Filed: 1956-05-14
Abstract: 802,705. Digital electric calculating apparatus. BRITISH TABULATING MACHINE CO., Ltd. May 1, 1957 [May 14, 1956], No. 14912/56. Class 106 (1). Digital electric adding (or subtracting) apparatus includes a first circuit which forms a first sum (or difference) signal group from binarycoded signal groups representing a first input digit (or its binary complement) and a filler digit, a second circuit which forms a second sum (or difference) signal group and a carry signal from signal groups representing the first sum (or difference) and a second input digit, and a third circuit which forms a third sum (or difference) signal group representing either the second sum (or difference) or the second sum (or difference) less the filler digit, in dependence on the occurrence or non-occurrence, respectively, of the carry signal. Binary-coded decimal signals representing the addend (A1, A2, A4, A8) and the augend (B1, B2, B4, B8) appear from an input device 17. Filler digits (F1, F2, F4, F8) are produced by a control unit 18 and each is applied via AND gates 3 to a first set of adders S1 to S4 together with the corresponding augend digit (B1 . . . B8). Another input on line 1 of the control unit 18 is ineffective during addition. Carriers are propagated via OR gates 4, and the sum signals pass via delay elements 5 to a second group of adders S5 . . . S8 to be combined with the addend digit entering via delay elements 6 on lines A1, A2, A4, A8. If this results in a carry from S8 to the next higher denomination the remainder passing via delay elements 8 to a third group of adders S9 . . . S12 is already correct and no further modification is necessary. If, however, there is no carry signal out of S8 then the filler digit must be subtracted to give the correct result. This is done by adding its 15-complement obtained by passing the delayed signals through inverters 11 and feeding these signals via AND gates 12 to the third group of adders S9 ... S12. A signal obtained from another inverter 13 in the absence of a carry signal from S8 opens the gates 12 and also supplies a signal to the adder S9 to correct the 15-complement to 16-complement. Subtraction is carried out in a similar manner in dependence on a control signal appearing on line 1; the 15-complement of the subtrahend B1 . . . B8 is formed in the adders S1 . . . S4 and added to the minuend A1 . . . A8 in the adders S5 . . . S8. If adder S8 does not produce a carry the 16-complement of the filler digits is added in adder S9 . . . S12; otherwise no further modification occurs. The circuit may be adjusted for other radices including British currency and other non-uniform systems.

Abstract: 783,211. Mass spectrometers. GENERAL ELECTRIC CO. May 25, 1955 [May 26, 1954], No. 15128/55. Class 39(1). Changes in pressure in the sample reservoir 25 or a mass spectrometer which are due to a temperature difference between the reservoir and the ionization chamber 27 maintained at different temperatures, are minimized by arranging the temperature gradient to fall between the ionization chamber and the leak 29. A part 32 of a heating coil 31 for the sample reservoir extends to the leak. Ionization chamber 27 has a heating coil 36 and a housing 30 provides heat insulated compartments. The proportion between the two heating currents may be kept constant when the absolute coupling values are altered. In an arrangement in which the ionization chamber is heated while the sample reservoir is kept at room temperature, a suitable length of flow tube is provided between the ionization chamber and the leak. The leak may be of the molecular flow type, or of the viscous, fractionating or non-fractionating type. A detailed analysis is given of the effects of thermal transpiration produced by thermal gradients in the gas inlet tube of the spectrometer. Specifications 632,963 and 698,850 are referred to.

Title: Improvements in or relating to the separation of molten metals by cooling
Inventor: KEEPING PATRICK ALEXANDER TEMP
IPC: C22B13/06
Filed: 1952-06-16
Abstract: 735,043. Liquation. NATIONAL SMELTING CO., Ltd. June 8, 1953 [June 16, 1952], No. 15132/52. Class 82 (1). [Also in Group XIII] Molten metals are separated from solution by cooling during passage through a trough or launder having cooling sections located therein, the metals being then passed to a quiescent body of the molten metal to complete the separation. Thus a solution obtained from the condensation of zinc vapour by shock chilling in a shower of molten lead may be separated into its component metals by cooling to a lower temperature above 418‹ C. Molten lead obtained from the separation is then returned to the zinc condenser. Fig. 1 shows a section of a cooling trough of sheet metal 4 having end flanges 5 for bolting a number of such sections together to form a trough of the required length. Detachable cooling jackets 2 are provided at the upper part of the trough, the lower part having a heat-insulating layer 3 of cement which may be extended as a thin layer 3a between the cooling jacket and the sheet steel of the trough. The level of molten metal in the trough and therefore the amount of cooling to which it is subjected is controlled, e.g. by a weir or mainspade with fine adjustment by a T-spade at the outlet end of the trough. Fig. 2 shows a trough receiving molten metal by pump 17 from the sump of a zinc condenser. After cooling the metal flows into separating tank 8 in which, while flowing slowly round partition 10, it forms an upper layer of zinc, which flows into tank 14, and a lower layerof lead which flows under baffle 11 and back into the zinc condenser. Specification 572,961 is referred to.

Title: A new or improved amusement device
IPC: A63F9/14
Filed: 1922-05-30
Abstract: 195,549. Cooper, J. May 30, 1922. Race games, mechanical.-A device for playing a competitive game of skill comprises a number of paths on which the figures of foxhounds &c. are adapted to move, a platform bearing the figure of a fox &c. and adapted to be moved to cross the paths of the foxhounds, and mechanical means for advancing the hounds towards the fox and to open and close the jaw of each hound as it comes within catching distance of the fox. The fox 24 is mounted on a revoluble platform 23 and the hounds 10 are caused to move along radial paths 1 by means of screws 8 rotated by handwheels 25. The extremities of the screws carry gear wheels 17 which drive the fox's platform 23 by means of pawls 18 and rollers 19, 20, the presence of the pawls giving the speed control of the fox's platform to the competitor who winds the fastest. As a hound approaches the fox's platform, a pin 28 rocks a three armed lever 29 connected by a cord 31 to the hound's jaw which is thus opened. At the same time the lever squeezes an air bag 32 to emit a sound approximating t'o a bark or bay. When the lever 29 slips past the pin 28 the jaw is closed by a spring 36 and if the competitor is successful the jaw closes upon and removes the fox's brush. At the completion of the inward movement of the hound a projection 40 on the winding screw 8 lifts the nut 14 off the screw, in which position it is retained by a catch 41, and the hound returns by gravity along its track which is sufficiently inclined for the purpose. At the starting point a collar 26 disengages the catch 41 and the nut 14 drops into engagement with the screw in readiness for another winding operation. The attendant may return all the hounds simultaneously to their starting positions by rotating an annulus 50 and thereby raising a series of levers 7 so as to disengage the nuts 14. Instead of the hounds returning under the influence of gravity, a cable and weight attached to each hound may be used to effect the, return. In a modification each hound is advanced by means of a winding drum and a cable, and at the end of the hound's forward movement a stop on the cable disengages the winding drum from its hand-wheel. A weight hanging from a cable then draws the hound back to the starting point where the winding drum is automatically re-engaged with its hand-wheel.
