Patent GB-466041-A (GB)
Title: Improvements in and relating to float chamber mechanism for internal combustion engines
IPC: F02M1/00
Filed: 1935-11-22
Abstract: 466,041. Spray carburetters; actuating materials. DODSON, E. Nov. 22, 1935, No. 32399. [Classes 7 (ii) and 7 (iii)] To reduce leakage due to vibration a pressure-sensitive device in or in communication with the induction system of an engine normally maintains a float-operated valve or an independent valve shut to cut off the inflow of liquid into a float-chamber, and retracts or relieves the valve when the pressure in the system varies from a pre-determined normal. In the construction shown in Fig. 1, the floatchamber contains a liquid which prevents the formation of ice in the induction system and the pressure-sensitive device is formed by a diaphragm g<1> which divides a casing f into two compartments both of which communicate through pipes with a detector unit in the induction system. Ice formation obstructs one of the pipes before'the other and the diaphragm g<1> then rocks a bell-crank lever e to depress a spring-loaded rod d<2> which normally holds the float-valve c on its seat thus allowing the valve to function under control of the float. In the construction shown in Fig. 4, the float chamber contains a liquid, e.g. alcohol, which prevents the formation of ice and also acts as an antidetonant. The float valve h is normally held on its seat independently of the float h<1> by a control member i which is pivotally connected to two valves j<1>, l<1> controlling the outflow of liquid from the chamber. The control member i releases the float-operated valve either when the valve j<1> is opened by a diaphragm n connected to the ice detector unit in the induction system or when the valve l<1> is opened, manually or by a pressure-sensitive device exposed to the pressure in the induction system, to supply the anti-detonating liquid. The invention is also applicable to a float chamber controlling the normal fuel supply to a multi-engine installation in which one or more engines may be stopped or fail to function, or to an additional float chamber between a carburetter and a higher supply tank. Specifications 356,410 and 414,410 are referred to.

Filed: 1925-12-24
Abstract: 269,618. Rose, W., and Rose Bros. (Gainsborough), Ltd. Dec. 24, 1925. Packeting by wrapping-up.-Relates to machines for wrapping caramels, blocks or like articles, according to the method described in Specification 255,289. An inner strip of white or coloured paper, metal foil or the like, of relatively small width, is applied to the caramel simultaneously with an outer transparent wrapper upon which is a design or printed matter, the strip being folded directly on to one or more sides of the block, and the outer wrapper being applied to the sides and ends. As shown, an inner strip 11, Fig. 6, is fed from a web 13, Fig. 1, and an outer wrapper 10, Fig. 4, is fed from a web 12. Feed-rollers 14, 15 forward the webs together through a guide 16 and are severed by a knife 17 at or about the time that a plunger 6 thrusts the block 5 and severed wrappers 10, 11 into a mould x on the wrapping wheel 1, or on a pivoted lever. The folding is completed by any suitable apparatus so that the strip 11 covers four sides of the block, and the outer wrapper 10 covers the four sides and is folded or twisted to close the packet. In a modification, the length of the inner strip is shorter than that of the outer wrapper, separate feeds being provided for this purpose. The inner strip may just overlap the end edges of the article, but not so as to cover any substantial portion of the end.

Patent GB-870990-A (GB)
Title: Air conditioning systems
IPC: B64D13/06
Filed: 1957-10-22
Abstract: 870,990. Fluid-pressure servomotor control systems. GARRETT CORPORATION. Oct. 22,1957 [Oct. 23, 1956], No. 32954/57. Class 135. Cold air is supplied to an aircraft cabin 10 from a compressor outlet 11, through a first cooler 12, compressor 14, second cooler 16, freeexpansion turbine -18 and a water separator 30, the latter being fitted with a porous ice collector 28, the pressure drop across which is employed to operate a control valve 33 regulating the pressure of the motive fluid operating the actuator 63 of a butterfly valve 27 regulating the supply of hot air into the cold air duct 20. The valve 27 is located in a cross connection 26 between the duct 20 and a by-pass 21 connecting the compressor outlet 11 and the cabin 10, and incorporating a valve 22 controlled by a cabin thermostat 24. Control valve 33 includes a pressure chamber 45 communicating with cross connection 26 and actuator 63 by pipes 59, 61 respectively, the pressure in the chamber being regulated by a needle valve 53 controlling a leak-off orifice 55. Valve 53 is connected to a small diaphragm 42 subjected on its underside to a loading spring 50, adjustable by a screwed sleeve 52, and on its upper side to atmospheric pressure through a port 58, and also subjected through a spindle 48 to the loading of a large control diaphragm 34, the upper and lower sides of which are subjected through pipes 70, 71 to the pressures on the upstream and downstream sides, respectively, of the ice collector 28. Normally needle valve 53 permits free leak-off through orifice 55 so that the pressure in chamber 45 and pipe 61 is substantially atmospheric, but as ice accumulates on the collector the increased pressure drop across it causes diaphragm 34 to move downwardly and needle valve 53 increasingly restricts flow through orifice 55, the increased pressure in pipe 61 acting on a spring-loaded diaphragm 64 in actuator 63 to open valve 27 and admit hot air into duct 20. As the ice melts the pressure drop is reduced and diaphragm 34 allows valve 53 to lift and the decreased pressure in pipe 61 tends to close valve 27. The valve 33 forms the subject matter of Specification 870,991.
