Abstract: 1,217,021. Spray carburetters. REGIE NATIONALE DES USINES RENAULT. Jan. 12, 1968 [Jan. 26, 1967], No. 1984/68. Addition to 1,151,365. Heading F1B. Fuel is automatically withdrawn from the float chamber, when the engine is stopped, by a spring- operated diaphragm pump 38, the fuel being returned when the engine is restarted. The pump 38 is connected by pipe 40 to the float chamber at the level n. The diaphragm 38 is connected to a frame 47 urged to the left by a spring 52, a second diaphragm 43 connected to the frame by link 47b being subjected to suction in the inlet manifold 15. When the engine stops, spring 52 force diaphragm 38 to the left, thereby lowering the fuel in the float chamber to the lever n. When the engine is restarted, the manifold suction in chamber 45 operates diaphragm 43 to force diaphragm 38 to the right, whereby the fuel in chamber 36 is returned through pipe 41 to the float chamber. A one way connector 50, 51 between a rod 48 and throttle lever 49 permits diaphragm 38 to be operated manually in the discharge direction by opening the throttle before the engine is restarted.

Abstract: 577,900. Controlling fuel pumps. LUCAS, Ltd., J., IFIELD, R. J., and NICOLLS, W. E. W. Aug. 11, 1942, No. 2020/43. Divided out of 577,016. [Class 135] A device for controlling the supply of liquid fuel from a pump to prime mover comprises a valve in a byepass passage connecting the pump inlet and outlet actuated by fluid pressure as under the control of a leak-off valve. As shown in the Figure, a pipe 67 connecting a sump to the pump inlet and a pipe 69 connecting the pump delivery to the prime mover pass through a chamber formed in a casing 68. The two pipes are connected by a byepass passage comprising ports 74, 81 and passages 73, 80 and controlled by a valve 78 mounted on a spring loaded diaphragm 70. The chamber 72 beneath the diaphragm is connected to the chamber 71 above the diaphragm by a passage 75 fitted with an adjustable restriction 76 and by a passage 75' to a leak-off orifice 87 controlled by a valve 88. This valve is loaded by a spring 89 and is actuated by a diaphragm adjustably loaded by a spring 91. A pump driven by the prime mover to deliver a pressure dependent on the speed of the prime mover is connected to a port 90 so that as the speed of the prime mover reaches a desired value the valve 88 is opened to vent the chamber 72 and open the valve 78 and so reduce the supply of fuel to the prime mover. In a modification, the valve 88 is actuated by a barometric capsule subject to atmospheric or induction pipe pressure. The barometric capsule is connected to the valve spindle by a pair of rollers connected by an adjustable roller.

Abstract: A method of producing a cellular structure in an uncured vinyl ester resin dispersed in sufficient plasticizer to provide a free flowing mass comprises moving the mass through a closed system, introducing an inert gas under pressure to entrain relatively large bubbles of the gas in the mass, mechanically beating the mass to break up and disperse the gas bubbles therein and discharging the material from a nozzle in ungelled state to form an expanded creamy foam.  Specified vinyl ester resins are polymers and copolymers of vinyl chloride. The mass may be chilled, e.g. to 15-65 DEG  F., while being mechanically beaten, and the gas pressure may exceed 100 lb. per sq. inch.  Small amounts ( 1/4 to 1/2 of one per cent) of sodium dioctyl sulphosuccinate or soyabean lecithin may be added to improve the gas absorption.  Specification 737,367 is referred to.
