Title: Improvements in or relating to supercharged internal combustion engines
IPC: F02D29/00
Filed: 1941-07-23
Abstract: 565,332. Carburetters ; actuating materials. BRISTOL AEROPLANE CO., Ltd., ANDERSON, G. O., PITT, A. C., THORNS, D. H., and RAMSAY, D. July 23, 1941, Nos. 9339 and 13057. [Classes 7 (ii) and 7 (iii)] Supercharged engines, particularly for aircraft, are provided with means for supplying an anti-detonant to the carburetter which also operates to weaken the fuel mixture and increase the boost pressure beyond the normal amount, the means being rendered inoperative if the supply of antidetonant should fail. In the form shown in Fig. 1, antidetonant is supplied by an electric pump 15 from a tank 13 when a switch 18 is closed by the throttle control 19. The pressure of the anti-detonant is conveyed to a capsule 22 which acts through a toggle 25 on the control rod 23 for weakening the mixture. The anti-detonant also acts underneath a diaphragm 27, Fig. 2, in a casing 26 so as to open a valve admitting the anti-detonant past a reducing-valve 38 to a connection 11 leading into the carburetter 10. The diaphragm 27 also opens a valve 33 so as to vent to atmosphere at 34 a conduit 36 which is connected to the bleed-orifice 12 of the automatic boost control, whereby the latter is over-ridden and the boost pressure increased above normal. The valve 33 may be replaced by a piston slide valve. When the supply of anti-detonant fails, the pump 15 is unable to produce the necessary pressure on the capsule 22 and diaphragm 27 for operating the parts connected thereto. In a modification, the anti-detonant is supplied under pressure from a float-controlled tank having a switch arranged in connection with the float so as to break the electric circuit when the supply fails. The electric current in this form actuates a solenoid which controls a valve for admitting the anti-detonant to the carburetter, and another valve for venting the boost-control chamber. A further valve opened by the boost pressure acting on a diaphragm may be placed between the first solenoidactuated valve and the carburetter. The solenoid also actuates the control for weakening the mixture. In another form, the throttle control lever acts directly on a valve for venting the boost control, and the increased boost pressure thus produced acts on a diaphragm to open a valve admitting the anti-detonant, and to weaken the fuel mixture through a servomotor connection ; when the supply of antidetonant fails, a float actuated thereby closes a valve which prevents the venting of the boost control. In a further construction, the antidetonant supplied by an electric pump acts on a diaphragm which vents the boost control and weakens the mixture by adjusting a differential bevel gear arranged in the pilot's control of the mixture strength. The anti-detonant may be water used alone or mixed with alcohol or methanol.

Filed: 1975-03-06
Abstract: 1459724 Cold-milling of cellulose derivatives HOECHST AG 6 March 1975 [7 March 1974] 9357/75 Heading C3A Particles of a cellulose derivative, preferably methyl cellulose, are formed by cold-milling the derivative when it contains from 40 to 150% of water based on its dry weight. The temperature of the cellulose derivative must be such that it is brittle, that is below the glass transition temperature of its amorphous regions. The cellulose derivative must be either watersoluble or water-swellable and must also be able to absorb more than 150% by weight of water at 20 C. The preferred coolant is liquid nitrogen. If preferred, the cellulose derivative may be densified before milling and the milled product is preferably dried to a water content of 10%.

Title: Improvements in or relating to modulated carrier wave transmitters
IPC: H03C1/20
Filed: 1935-03-27
Abstract: 454,259. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and DITCHAM, W. T., Tudor House, Broomfield Road, Chelmsford. March 27, 1935, No. 9575. [Class 40 (v)] The output of a carrier-wave generator or amplifier V1 is modulated by two valves V2, V3 which are excited in opposite phase by the modulating voltage and are connected respectively in shunt and in series with the valve V1. Both valves V2, V3 are biassed back to zero plate current, and they pass current alternately during the respective half-cycles of the modulating voltage applied to their grids by the transformers T1, T2. When the valve V2 is conductive the carrierwave output of the amplifier V1 is reduced by virtue of the iron-cored choke L in the plate supply circuit both of valve V1, and of valve V2, and connected between a D.C. source El and the cathodes. When the valve V3 is conductive, the second source E2 contributes to the plate current of the valve V1 and the carrier output rises. No current passes in the valves V2 V3 in the absence of modulating signals. Several valves in parallel may replace any of the valves V1, V2, V3.
