Patent GB-141795-A (GB)
Title: A carburetter for internal combustion engines
IPC: F02M1/00
Filed: 1919-01-20
Abstract: 141,795. Elverson, J., and Elverson, J. Jan. 20, 1919. Spray carburettors.- In a carburettor of the type in which the fuel is vaporized by the action of gauze, more or lees of which is brought into action by the movement of the throttle, a roll of gauze a is wrapped round a tube b heated by hot air, hot water, or exhaust gases. A tube c surrounds the gauze and terminates in a chamber c to which fuel is sup. plied from a float chamber d, the level of the fuel in the tube c being slightly above the centre line of the tube b. Air enters the carburettor through an inlet g<5> and passes over the tube e, which has a port e<1> exposing part of the gauze and controlled by means of a slotted rotatable sleeve f adjusted by a stud f<2>. The vapour and air are throttled simultaneously by means of sliding sleeves g, g<2> respectively, which are connected together and actuated by a lever h; in addition, a rotational adjustment of these sleeves, by means of a stud g<4>, may be used if desired, as at starting, to increase the air speed over the exposed surface. A partial vacuum is maintained in the float chamber by means of a passage h<2> leading to the suction side of the carburettor, a ball valve h<1>, and a small adjustable air inlet d<4>. The maintenance of the fuel at a relatively high temperature is stated to reduce the effects of alterations of altitude or barometrical pressure, and all the adjustments required for any given conditions can be made whilst the engine is running. By closing the sleeve f and opening the throttle, a cooling and braking action is obtained.

An electroluminescent lamp comprises two electrodes one of which is transparent, and between them two layers in contact each of a mixture of phosphor and dielectric material. A mixture of ceramic or glass and phosphor e.g. copper activated zinc sulphide is suspended in a liquid comprising methyl alcohol and isopropyl alcohol (equal volumes) and allowed to settle onto an enamel coating or a metal plate, for about 15 minutes. After partial and thorough drying its coating is fired at 1150‹F. A further layer of the mixture is settled onto the coating using the same method and after drying, fired at 1250‹F. The suspension liquid may be toluol or water. The ceramic part of the mixture may comprise CaO, BaO, ZnO, SiO 2  B 2 O 3 , Na 2 O, PbO and other oxides.

Title: Improvements in free-piston internal combustion operated compressors or gas generators
IPC: F02B3/06
Filed: 1945-01-25
Abstract: 595,460. Free-piston compressors or gas generators. ENGLISH ELECTRIC CO., Ltd., WELSH, R. J., and FITZHERBERT, A. B. Jan. 25, 1945, Nos. 1981 and 2841. [Classes 7 (i) and 7 (ii)] In a free piston compressor or gas generator a single acting compressor cylinder closed on the idle or non-working side of the compressor piston is provided with means which are arranged under normal running conditions to equalise the mean effective pressure in the closed part of the cylinder with the pressure at the inlet to the compressor. As shown, .the compressor 2 compresses air for scavenging an engine cylinder 1 which supplies exhaust gases to a turbine 25. The air is compressed only on the side 2a of the piston 5 of the compressor, the side 2b being an enclosed idle space having a port 50 in the cylinder wall for the purpose of maintaining the pressure in this space equal to the pressure at the inlet to compressor. The position of the port is chosen so that over the whole stroke of the piston the mean effective pressure has the desired value. A non-return valve 51 between the port and a chamber 14a at the compressor inlet, allows air to escape from the idle space if the pressure in it exceeds the pressure at the compressor inlet during the time-the port is uncovered. A non-return valve 55 is provided between the scavenging air chamber 15b and the idle space to relieve the pressure in the idle space during starting. Leak holes may be provided such as either 52, 53 or 54 which are stated to make up the pressure in the idle space if this falls below the desired value. In an alternative construction the piston 5 has an extended skirt incorporating a port which opens the idle space to the compressor inlet chamber at one point only of the stroke. In a second alternative the idle space is connected to the compressor inlet during the whole of the stroke by means of a restricted orifice which enables the mean effective pressure in the idle space to adjust itself to equality with the pressure at the compressor inlet. As shown, the turbine has a governor 88 which controls conjointly the fuel supply and a throttle in the inlet of each compressor. Buffer cylinders 3 are provided at each end of the engine.

Title: Improvements in or relating to electrical apparatus and the method of cooling same
Inventor: KAEHNI FRANK JOSEPH
IPC: H01F27/08
Filed: 1953-01-28
Abstract: 728,319. Cooling transformers and dynamoelectric machines. METAL CARBIDES CORPORATION. Jan. 28, 1953, No: 2428/53. Classes 35 and 38 (2). [Also in Group XIII] The cooling of electrical apparatus such as a transformer generator, motor, rectifier or condenser immersed in a liquid such as oil, includes subjecting part of the fluid to a high unidirectional potential, whereby the electrostatic field produced therein produces relatively rapid currents in the liquid. Thus, if high potential is applied from sources 3 between the earthed casing 6 of transformer 5, and the high voltage windings 2, oil currents pass from this winding to the casing and back again, thus transferring the heat more rapidly than the normal thermal convection currents. In modifications, the voltage may be applied between an electrode immersed in the oil, and the casing and/or high voltage winding, Figs. 2, 3 (not shown), or between a cooling coil 10 in the oil, and the high voltage winding 2, Fig. 4, and, if desired, an electrode, Fig. 5 (not shown). Where, as shown in Fig. 7, the oil is circulated by pump 16 through an external heat exchanger, the potential may be applied not only in the transformer, e.g. between casing 6 and electrode 8, but also in the heat exchanger between an electrode 20 and the walls 14, 17 which contain respectively the oil and the cooling fluid such as water. Connection of the potential between the casing and high voltage winding of one transformer may be effective in all transformers connected to the system, Fig. 8 (not shown). Fig. 9 shows a shell type transformer with a high voltage winding composed of two layers of bare flat strip 22 wound with insulation 23 between the turns, and a low tension winding of tubing 4 through which cooling fluid is passed. The potential is set up between the winding 4 and casing 6 and the winding 22, the bare edges of which enhance the cooling. Electrodes may be placed in various parts of the transformer, including in the oil ducts, and any part of the transformer which acts as electrode, which may include the core, may bear points or sharp edges. The spacing between the electrodes should be small, compatible with insulation needs.
