Title: Improvements in or relating to means for driving and controlling feed-water pumps
IPC: F04D13/02
Filed: 1934-03-10
Abstract: 431,215. Regulating delivery of pumps. WEIR, Ltd., G. & J., and HILLIER, H., Holm Foundry, Cathcart, Glasgow. March 10, 1934, No. 7618. [Class 102 (i)] [See also Group XXVI] The speed of a boiler-feed pump is regulated in accordance with the demand from the boiler by controlling the flow of oil to an hydraulic coupling connecting the pump and the driving motor. The oil flows between the coupling 3 and the reservoir 14 via a valve 12 which is adapted to be displaced downwardly in opposition to the action of a spring 21 by fluid pressure from a constant pressure supply 22. The fluid passes to a leak-off 25 which is controlled by a lever 26. One side of the lever is by means of a piston 36, subject to the boiler pressure on one side of a feed regulator 31 and the other side, by means of a piston 35, to the pump discharge pressure. When the feed regulator 31 opens due to a demand from the boiler for more water, the pressure at 35 falls and the leak-off 25 opens. The reduction of pressure on the diaphragm 20 causes the valve 12 to lift and oil flows to the coupling with a consequent increase in pump speed. When the requisite speed to supply the demand has been attained the acceleration is stopped by a speed governor 38 which closes the leak-off and restores the valve 12 to its neutral position. Adjustments are made by springs 37, 46. In various modifications, the valve 12 is actuated directly by the pumped fluid. In one modification the pipes from each side of the regulator 31 pass to opposite sides of a piston which actuates the valve 12. The acceleration is stopped by a second valve in series with the valve 12 and actuated by the speed governor. In another modification, the acceleration is stopped by a float valve in the oil reservoir and which functions in accordance with the quantity of oil withdrawn from the coupling. In a further modification the acceleration is stopped by a pressure responsive device connected to a Venturi meter in the pump discharge. The device returns the valve 12 to its neutral position. A number of feed regulators may be coupled in parallel. To enable several pumps to operate in parallel the discharge of the oil pumps 15 are connected to a common discharge main 65 with a relief valve set at a desired pressure. The reservoir 14 may be coupled by a bus line 67.

Title: Improvements relating to control mechanism for apparatus operated by fluid under pressure
IPC: B60T11/10
Filed: 1943-05-13
Abstract: 568,266. Fluid-pressure operated brakes. TOMLINSON, A. V. (Bendix Westinghouse Automotive Air Brake Co.). May 13, 1943, No. 7637. [Class 103 (i)] [Also in Group XXXVII] Fluid - pressure apparatus particularly for operating brakes comprises electrically operated valves adapted to supply pressure fluid to or release it from a brake cylinder or the like and rendered operative by means responsive to the flow of fluid supplied to or released from the brake cylinder or the like by a main control valve. The brake system shown comprises a self-lapping main valve device 1 comprising a chamber 3 normally connected to atmosphere through a tubular valve-operating member 17 and ports 25, 22. When the pedal 26 is depressed the member 17 is moved downward by a spring 27 to seat the exhaust valve 15a and unseat the supply valve 13 to admit compressed air from reservoirs 9, 10 to the chamber 3. If the pedal is held in a given depressed position, the pressure fluid in chamber 3 flowing through a restricted passage 21 to a chamber 19 acts upon a diaphragm 18 to return the member 17 sufficiently to close the supply valve 13. Pressure is thus built up in chamber 3 to a value dependent upon the extent of movement of the pedal. The chamber 3 is connected to the brake-operating motor 4 by pipes 5, 7 and the chamber 31 of a switch device 6 comprising a vane pivoted at 33 and movable in either direction against the action of springs 36, 37 to engage contacts 34, 35 and thus to complete the circuits respectively of magnet valves 55, 49 from a battery 60 through conductor 61 the valve coils, conductors 58, 59 the contacts 34, 35, the vane 32 and the conductor 62. The valve device 49 comprises a valve 46 which normally closes a connection from the reservoir 9 to the motor 4 through pipes 45, 44 and the valve 51a of the valve device 55 normally closes a connection of the motor to atmosphere through pipes 44, 53, 52. The compressed air supplied to the chamber 3 upon depression of the pedal flows to the motor 4 through the chamber of the switch device 6 and if the speed of flow is sufficient the vane 32 engages the contact 35 against the action of the spring 37 thus energizing the valve 49 so that air is supplied to the motor also through this valve. When the main valve 1 assumes the lap position the vane 32 returns and the valve 49 closes. Similarly during the release operation, the air flowing from the motor through the chamber of the switch to the exhaust valve 15a, if the speed of flow is sufficient, moves the vane against the contact 34, thus energizing the valve 55 to open the exhaust passage 52 for the motor.

Title: Improvements in or relating to snap-acting electric thermostats
IPC: H05B1/02
Filed: 1939-03-10
Abstract: 527,630. Thermal switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 10, 1939, No. 7752. Convention date, March 25, 1938. [Class 38 (v)] A thermal switch comprises a contact arm 20 fulcrummed at its left hand end on a slotted stud 36 and carrying near its other end a contact 17 for engagement with pairs of fixed contacts 16, 18. The arm 20 is formed with side wings 16 to which are riveted the ends of a blade spring 22 which passes through an aperture 42 in the arm where its middle point is held by an adjustable stud 53. This serves to make the contact arm engage one or other pair of fixed contacts and to move with a snap-action. The slotted free end of the arm 20 engages, with lost motion, a groove in an impact pin 24 which is coupled by a spring clip 75 to the free end of a bimetallic strip 28 clamped at 92. The upper end of pin 24 is provided with adjustable nuts 80, 84 for damping a blade spring 26. This results in the pin 24 moving suddenly and operating the arm 20 with snap-action. The operating temperature is varied by means of a screw 34 bearing on the bimetallic strip and the differential is varied by means of the clamping nuts 80, 84.

Title: Improvements in and relating to variable speed and reversing gearing
IPC: F16H33/10
Filed: 1933-03-15
Abstract: 416,032. Variable-speed gearing; gyroscopic apparatus. RICHARDS, R. W., 824, Coventry Road, Small Heath, Birmingham. March 15, 1933, No. 7903. [Class 80 (ii).] Variable-speed gearing suitable for vehicles comprises a spherical gyroscopic mass 25 universally connected at its periphery to a driving housing 24, Fig. 1, and adapted to transmit precessional motion to an axially slidable shaft or member 2 in line with the housing 24. A pin 30 passes diametrally through the mass 25 and is supported in bearings 31, 32 so as to turn freely relatively thereto. Between the pin 30 and the shaft 2 is a universallyjointed link 14. Springs 16 on bolts 34 carried by the housing 24 through a bell 19 and bearing 17 pull the shaft 2 to the right so as to produce a couple tending to tilt the pin 30 in the plane of Fig. 1. This couple causes precession in the mass 25 so that the pin axle 30 revolves conically and so drives the shaft 2. Control is superposed by opposing to the pull of the springs 16 thrust exerted by a lever 35, which thrust may be produced by foot pressure, or by engine suction in a cylinder 46. A drive in which speed and torque vary automatically is passed on through a universal joint 43 which has slots 42 permitting longitudinal displacements of the shaft 2. Rollers 29 carried by the housing 24 engage slots 28 in the periphery of the mass 25 so as to drive the latter while allowing angular adjustment, and the rotary speed of the mass 25 is rendered uniform by a cam formation of the slots 28 shown in Fig. 2. By reversing the axial thrust on the shaft 2, the torque transmitted may be reversed so as to exert a braking action upon or so as to reverse the drive imparted to, the driven shaft. In the arrangement described in the Provisional Specification, the gyroscopic mass is an inclinable flywheel driven universally on one side and carrying on the other side a stub shaft turning freely in a bearing supported in trunnions in a balance-weighted crank link corresponding to the link 14 of Fig. 1.

Abstract: 535,597. Cranes mounted on vehicles. TREDEGAR, E. F. MORGAN, VISCOUNT. (Falcke, D.). May 7, 1940, No. 8226. [Class 78 (iv)] Turntable cranes carried on vehicles are provided with additional ground-engaging supports to the rear of the road wheels of the vehicle. Fig. 2 shows a turntable 16 mounted to overhang the narrowed chassis 10 at the sides and rear. Two pairs of inverted, V-shaped legs 19, 20 fixed to the table are set so that the plane of each pair is radial to the turntable and at about 30 degrees to the longitudinal axis of the vehicle, the two pairs being on opposite sides of the longitudinal axis and being formed as hydraulic cylinders, the rams of which carry pneumatic-tyred castor wheels set tangentially to the turntable. When the pistons are retracted, the castor wheels are clear of the ground, but when extended, each engages the ground independently, thus allowing the apparatus to function on uneven ground. A chain tie 28 completes a triangular leg structure when the pistons are fully extended. The turntable may carry the usual luffing jib mounted on a horizontal axis, or as shown, may be fixed to the turntable and carry a sliding extension 18.

An elongated metal element, e.g. carbon-or alloy-steel wire strand or rope, strip or rod, is heat treated, e.g. tempered after oil quenching, stress relieved after drawing or hot stretched, by advancing the element, e.g. steel wire 21, in straight configuration first into a heated liquid bath, e.g. a salt or lead bath 10 contained in an inclined tube 11, through an orifice e.g. of a WC die 19 in an upstanding end wall 18 of the bath, the orifice being disposed below the liquid surface level 10a and of bore greater than the diameter of the element by an amount sufficient to permit free passage of the element through the orifice, then to and through the liquid surface level 10a. During advancement, a force is applied to the liquid in a direction to resist its leakage out of the bath between the advancing element and the adjacent wall of the orifice. The bore of the orifice may be e.g. 0.060 inch just greater than the diameter e.g. 0À058 inch of the wire 21, to achieve this force; or the wire may first pass through a chamber supplied with air under pressure surrounding the orifice.

Title: Improvements in and relating to light and smoke signals for aeronautical and marine use
IPC: B63B51/04
Filed: 1940-05-17
Abstract: 566,974. Signalling by visible signals. HOLMES' MARINE LIFE PROTECTION ASSOCIATION, Ltd., and TOPLEY, B. May 17, 1940, No. 8849. [Class 118 (ii)] [Also in Group III] Relates to signalling apparatus of the kind in which admission of water to a chemical liberates an inflammable gas to produce light or smoke, or both. According to the invention, commercial calcium phosphide which is usually used for the purpose is replaced by a phosphide produced by direct combination of phosphorus with metallic magnesium or calcium. The magnesium phosphide is prepared by passing the vapour of phosphorus over magnesium heated to 500‹ C. in a chamber from which air is excluded. Alloys rich in magnesium may be used instead of the pure metal. The phosphine produced by reaction of these compounds with water may not be self-igniting, but may be made so by mixing with the compound a small quantity of commercial calcium phosphide or by introducing a small proportion of nitric oxide into the air in which the phosphine burns. A flare signal for floating on water may comprise a cylindrical chamber 2 having a rounded base and enclosing magnesium phosphide 1, prepared according to the invention, mixed with some commercial calcium phosphide. The rounded base is perforated with a central hole 4 from which a tube 5 extends axially through the chamber 2 and through a float chamber 6. The tube is perforated within the chamber 2 and emerges from the upper end of the float chamber to provide a vent for the escape of gas. Removable plates 14, 13 seal the upper and lower ends, respectively, of the tube.
