Patent GB-1065773-A (GB)
Title: Photoelectric transducers
IPC: H01B1/00
Filed: 1964-03-16
Abstract: In a photo-electric transducer the photo-sensitive material comprises a mixture of a semi-conductor material and a luminescent material, the ratio of the former to the latter being greater than 10%. Suggested semi-conductor materials are Ge, Si, Se, Cu2O, ZnO, <PICT:1065773/C4-C5/1> PbO, NiO, CdS, ZnSe and anthracene, while the fluorescent material may be zinc sulphide, calcium sulphide, scheelite, willemite or (Zn, Cd)S.  These materials may be dispersed in an electrical insulator such as silicone resin, polyvinyl chloride, epoxy resin, glass or porcelain. The device may be made up as a layer 5 of such a mixture on an insulator 6 and having one electrode 8 adjacent to the insulating layer and a transparent electrode 7 adjacent to the layer 5, with or without the interposition of a further insulating layer.  If such a device is charged by a voltage source 9 and then disconnected, but exposed to light, the voltage across the electrodes increases, depending on the intensity of the light.  If electroluminescent material such as ZnS or (Zn.Cd)S is used with semi-conductor material such as ZnO, NiO, Ge, Cu2O, the device will emit light on application of an A.C. voltage.  In making the device a mixture of semi-conductor material and fluorescent material may be heated to a temperature sufficiently high to cause the semi-conductor to melt and subsequently allowing it to recrystallize.  Alternatively, it may be heated sufficiently to cause an additional constituent, such as NaCl or ZnCl2, to melt, and then dissolve the semi-conductor material, after which the latter is allowed to recrystallize.

Title: Nickel alloys
IPC: C22C19/05
Filed: 1922-04-25
Abstract: 201,226. Saltrick, W. R. April 25, 1922. Alloys containing iron, nickel and chromium. with or without other metals such as copper and manganese, are made by reducing a chromium compound or ore such as chromite, and other ores or compounds where necessary, with a nickel silicon alloy or nickel silicide, particularly a nickel chromium alloy low in carbon and high in silicon. The nickel silicon alloy may be obtained by smelting an ore such as garnierite with carbonaceous material, and may be used as the reducing agent for chromite in an electric furnace; or it may be mixed with the ore and the mixture added to molten steel. Briquettes may be used in some cases, and these may be weighted by the addition of metals to the mixture to facilitate addition to the bath. The iron nickel chromium alloy may be refined by the use of solid reagents or by blowing with an oxidizing medium, for example air followed by steam. Additional quantities of the same or other metals may be added to the alloy either in the form of metals or alloys such as ferro-chrome, or by means of mixtures of an ore or compound with a silicon alloy or silicide. The first Provisional Specification refers also to alloys containing tungsten. Specifications 202,345 and 202,664 are referred to.

Abstract: 389,292. Change-speed gearing; driving fans. FARMAN, H. and FARMAN, M., (trading as FARMAN, H. ET M.), 149, Rue de Silly, Billancourt, Seine, France. April 22, 1932, No. 11633. Convention date, April 24, 1931. Addition to 349,438. [Class 80 (ii).] The change-speed gear for driving a charging fan for an internal-combustion engine according to the parent Specification is controlled by coordinated cams 17, 18 preferably fast on the same shaft 16 and controlled by one lever 15. The left and right halves of Fig. 1 are sections on AA and BB of Fig. 2. Two countershafts 5a transmit the same high speed between a driving- shaft 2 and the fan shaft 1. A countershaft 5b transmits a lower disconnectable speed. With the lever 15 in position I, the friction clutches are all open and there is either no drive, or a lowest speed through an optional countershaft 22 and a free-wheel. The friction clutches are held open by bosses 13a, 13b held pressed downwards of Fig. 1 by the cams 17, 18 so as to prevent centrifugal levers 12a, 12b from automatically engaging the clutches. When the lever 15 is moved to position II, a gap 34 in the cam 17 allows a lever 19 to move downwards on the left of Fig. 1 so as to free the centrifugal levers 12b, engage the clutch 8b, and bring a train 3, 6b, 5b, 7b, 4 into operation. Continued movement of the lever 15 to position III disconnects the clutch 8b and lets both clutches 8a engage so that both high-speed trains 3, 6a, 5a, 7a, 4 are operative. The two bosses 13a are connected to a balancing slider 21 which is allowed to move downwards of Fig. 1 by a recess 39 in the cam 18 to allow the two sets of centrifugal levers 12a to act.

Abstract: 992,107. Differential gear; toothed gearing. CATERPILLAR TRACTOR CO. March 20, 1964 [April 1, 1963], No. 11848/64. Drawings to Specification. Headings F2D and F2Q. A limited slip differential gear for motor vehicles comprises an input carrier mounting sets of three intermeshed helically-toothed pinions arranged radially with the outer pinions of each set meshing helicallytoothed face gears splined for axial movement upon half-shafts and biased inwards towards the pinions for tooth loading by stacks of Belleville springs within the differential casing. Should one or other of the half-shafts spin, as with vehicle road wheel slip, the friction between the teeth of the outer pinions and the teeth of the face gears opposes relative movement between the gear parts. If the torque transmitted is sufficient, either one or both of the facially - toothed gears is forced back, collapsing its stack of Belleville springs into friction driving engagement. The flank angles of the teeth upon the gears and pinions are steeper on one side of each tooth than the other, Fig. 3 (not shown), so that in operation with a spinning half-shaft, increasing the torque transmitted always collapses one stack of Belleville springs before both are collapsed.

IPC: F02M19/035
Filed: 1921-04-28
Abstract: 168,852. Matricardi, G. Sept. 8, 1920, [Convention date]. Spray carburettors.-A separate suction conduit placed concentrically over the nozzle and leading to the induction pipe beyond the throttle valve is provided to increase the fuel flow at low speeds and small throttle openings, the effect of the conduit diminishing as the throttle is opened to increase the speed. The percentage of fuel in the mixture therefore decreases as the speed increases and vice versa. The casing 1 contains a rotatable throttle valve 3 carrying a choke tube 4 and having mixture outlet ports 5 leading to the outlet passage 2. The fuel nozzle 12 is supplied from a float chamber 7, in which the float 8 and valve 9 are connected through a blade spring 10 to prevent damage to the valve through vibration and shock. Above the nozzle outlet is a tube 13 adjustable by a screw 19 and leading through a chamber 14, pipe 15, and port 16 in the case of a light fuel or through a pipe 17 passing through the exhaust passage 18 in the case of a heavy fuel being used, to the induction pipe on the engine side of the throttle valve. The whole of the air passes through the annular space between the choke tube 4 and the nozzle 12 and the whole of the fuel passes through the suction conduit 13. A cock 11 controls the fuel flow to the nozzle and when a heavy fuel is used is closed at starting and a light fuel injected at 16. The composition of the mixture throughout the range of throttle openings is determined by the distance of the tube 13 from the nozzle 12.
