Abstract: 1503096 Fuel injection pumps; fuel injection systems WISSENSCHAFTLICH-TECHNISCHES ZENTRUM AUTOMOBILBAU KARL-MARXSTADT 29 April 1976 [16 May 1975] 17431/76 Headings F1A and F1B Fuel injection pumping apparatus comprises a pumping piston 81 driven by a fuel-actuated motor piston 80 to pump fuel from a working chamber 811 to an injection nozzle 9, the quantity of fuel delivered being determined by the duration of current supply to an electrically actuated valve 6 controlling the supply of actuating fuel to the motor piston 80. Energization of the valve 6 connects a cylinder 71 of a valve 7 to a pressure line 51 instead of to a drain line 10. Pressurization of the cylinder 71 in turn causes the valve 7 to changeover and connect the space above the motor piston 80 to the pressure line 51 instead of to the drain line 10. On de-energization of the valve 6 the valves 6, 7 return to their positions shown and the pistons are returned to their starting positions shown by the flow of fuel from line 51 past a non-return valve 82 into the chamber 811. A pump 3 pressurizes the line 51 and an accumulator 5 connected thereto to a pressure determined by a valve 4.

Abstract: 362,952. Hydraulic transmission of power. SALERNI, P. M., 23, Carlton House Terrace, London. June 10, 1930, Nos. 17864/30, 18098/30, 18924/30, 24949/30, 27931/30, 27932/30, 32052/30, and 10597/31. [Class 69 (ii).] In hydraulic power transmission apparatus of the F÷ttinger type, the tips of the leading ends of the impeller and/or turbine vanes are at such an angle as to be parallel or approximately parallel to the direction of flow relatively thereto, so as to avoid impact losses and thus enable the turbine torque to differ from the impeller torque. The angle may be such, as shown in Figs. 2 and 4, as to enable power to be transmitted at a range of low torque ratios approximating 1 to 1, or, as shown in Fig. 8, to enable transmission to be effected at a range of high torque ratios, e.g. from 1À5 to 1 to 4 to 1. Such a transmitter may be associated with mechanical or other gearing, for obtaining reverse drive or another ratio for forward drive, and may be used in the power transmission mechanism described in Specification 361,281. The form shown in Fig. 9 has two hydraulic circuits, the outer having vanes A, B for the low ratio transmission, 'and the inner having vanes C, D for high ratio transmission; a valve E is provided by means of which either or both circuits may be closed.- A third circuit also controlled by the valve may be provided for reverse drive. According to the sixth Provisional Specification, the valve may be slidable on balls or rollers. A single transmitter may be provided with a third element G, Fig. 11, carrying vanes G<1> and normally free to rotate ; when the element G is held by a brake G<4> the drive is reversed. In order to facilitate manufacture, the vanes may be carried by separate members or shells a<1>, a<2>, b<1>, b<2>, Fig. 12, and the assembled parts held by bolts a<3>, b<3>. The vanes and other parts in contact with the liquid may be treated to produce a smooth surface, and when made of soft material, such as aluminium or alloys thereof, they may be plated with chromium.

Abstract: 569,769. Fuel supply systems. GENERAL MOTORS CORPORATION. Oct. 30, 1943, No. 17968. Convention date, Aug. 31, 1942. [Class 7 (iii)] [Also in Groups XXVIII and XXIX] A fuel supply system comprises conduits 37, 21, 19, 33, Fig. 1, including a pump 17 adapted to maintain continuously superatmospheric pressure in the system, means such as a pipe 23 for withdrawing fuel from the system to a carburetter 13 and a venturi 39 in the fuel tank and responsive to the reduction in the pressure caused by the withdrawal, to replace the fuel withdrawn from the system with fuel from the tank 15. The ends of the delivery pipe 19, 33 and the inlet pipe 37, 21 of the pump terminate in a casing 49, 51, Fig. 2, having a gauze wall 55 and disposed at the bottom of the tank 15, the pipe 37 ending in the venturi 39, the throat 41 of which is opposite a nozzle 73 leading from a filter chamber 69 in the casing. The chamber 69 is fed from a chamber 67 beneath the delivery pipe 33 when pressure of the fuel depresses a plunger 57 against a spring 59; if air bubbles are present, the necessary pressure is not attained and the bubbles escape through a side passage 65 into the tank. When withdrawal of fuel by the carburetter 13 occurs, the venturi 39 draws in fresh fuel to replace it. The fuel pump 17 is double-acting and comprises rigidly interconnected diaphragms 107, 109 raised by a cam-operated lever 99 acting through a spring 117 and lowered by a spring 119 compressed on the upward movement, the diaphragms receiving fuel from a common inlet and delivering it to a common outlet, the fuel through valves each comprising a cupshaped valve member 165, Fig. 7, in a cage 161 which houses a retaining spring 163.

Abstract: 1384010 Pyrolysis of waste materials AWT SYSTEMS Inc 16 April 1973 18131/73 Heading C5E [Also in Division F4] Solid waste is pyrolysed in a first fluidized bed supported on a distributer plate 40 sloping downwardly to an outlet below which a second fluidized bed is formed in a pipe 42 so that heavy uncombusted material sinks to the bottom of the pipe 42 and can be removed through an air lock. The waste is fed to an inlet in the side of the sloping distributer plate 40 by a screw conveyer 38 which receives waste cut from a plug at the end of a supply screw conveyer 15 by a rotating device 18. If the plug is insufficient to seal the supply system from the atmosphere, the device 18 is moved to seal the end of the casing 16 of conveyer 15. The fluidizing air or gas is fed to a plenum chamber surrounding the lower fluidized bed tube 42 through two inlets, and the holes 62, 63 in the plate 40 and tube 42 and the air feed is such that the upper bed is supplied with gas at more than twice the minimum fluidizing velocity, while the lower bed is fed with gas at a velocity between 1À2 and 1À5 times the minimum fluidizing velocity. The gas supplied to the plenum may be oxygen free in order to pyrolyse the waste. A housing 64 encloses burners for start-up or pyrolysis and an expansion chamber and cyclone 66 separate fly ash from the exhaust gases.

Title: Loud speaking telephone systems
IPC: H04M9/00
Filed: 1944-09-29
Abstract: 608,850. Loud-speaking telephone systems. AUTOPHON AKT.-GES. Sept 29, 1944, No. 18710. Convention date, Jan. 15. [Class 40 (iv)] In a loud-speaking system the substation amplifiers have their direction of transmission changed over at the end of each speech train. In the exchange equipment, Fig. 3, the polarity sent out by contacts of relay I over the phantom circuits to the substations determines the speaking direction of amplifiers located therein. Speech currents in either direction are rectified by valve R to operate relay SP which is followed by slow release relay SPI. At the end of a speech train these relays apply a momentary earth to the relay combination I, II. If both these relays are unoperated, I operates over its coil Ib and when the earth is removed and the circuit 14, IIa, Ia is therefore no longer shortcircuited, relay II operates and I holds over its coil Ia in series with IIa and IIb. When at the end of another speech train momentary earth is again applied to the combination, coil Ia is shunted down and 14 opens so that when the earth is removed relay II falls and both relays are again unoperated. The speaking direction may also be changed manually by either subscriber momentarily opening his phantom circuit as described in Specification 596,662 to release J or Y whose contacts deliver the necessary earthed impulses to the relay set. In a modification, Fig. 1 (not shown), the change-over means is voice-controlled only and is operated by changing the direction of the battery around the loop, there being only one voice-operated relay having a make contact which shunts the circuit 14, Ia, IIa. In a similar arrangement, Fig. 4, in which the change-over apparatus is located wholly at the substation, the relay II operates the amplifier change-over contacts directly, speech currents being amplified by valve R and then rectified to operate relay SP. A subscriber wishing to break in operates the switch T so disconnecting his voice-operated circuit at T2 and releasing relay II at T1 to put his amplifier into the transmitting condition. At the same time a tone signal comprising two frequencies is injected into the line by means not shown to operate the distant subscriber's tuned relays FI, FII which energize the relay II over coil IIb to put the amplifier in the receive condition. In another embodiment, Fig. 2 (not shown), a voice-operated relay controls a two-position switch which puts the amplifier alternately into the transmit and receive conditions.
