Patent GB-673867-A (GB)
Title: Improvements relating to electro-magnetic relays
IPC: H01H51/32
Filed: 1949-09-02
Abstract: 673,867. Electromagnetic switches. CARPENTER, R. E. H. Aug. 29, 1950. [Sept. 2, 1949] No. 22847/49. Class 38 (v). Chatter between contacts is eliminated or reduced by mounting a mass on the support of one or both of the contacts so that it can move under friction relatively to the support and does so move owing to its inertia when the contacts engage. The invention is shown (Fig. 2) applied to a relay of the kind described in Specification 619,546, wherein the armature 2 carries contacts 3 adapted to engage one or other of two fixed contacts 4 according to whether the armature moves up or down. The invention is here applied to both the moving and fixed contacts. The moving contact support, i.e. the armature 2 carries a mass 6 pressed against a washer 11 of "Catalin" (Registered Trade Mark) by a centering spring 13. When the contacts 3, 4 collide the mass 6 continues its motion owing to its inertia sliding frictionally on the washer 11. Each fixed contact 4 is carried on a stiff spring 15 which carries at its end a bent strip of metal 23 constituting the mass and embracing a strip of neoprene 22 which embraces the end 21. Any tendency of the strip 15 to vibrate is checked by the inertia of the mass 23 which causes frictional distortion of the neoprene 22. In modifications a ring of neoprene is mounted on the end of the spring 15, Figs. 12, 13 (not shown), and a mass bears frictionally on the spring 15, Figs. 16, 17 (not shown). In other modifications for the moving contact member, the mass 6 instead of moving rectilinearly moves pivotally, Figs. 5, 6 (not shown), the mass consists of a piston moving in oil, Fig. 7 (not shown), or of a disc mounted between two felt washers, Figs. 8, 9 (not shown).

Title: Guided missile system
IPC: F41G7/30
Filed: 1965-05-28
Abstract: 1486537 Guiding missiles PHILCO FORD CORP 28 May 1965 [28 May 1964] 22880/65 Heading H4D The course 11 of a ground-to-ground guided missile 14 is maintained along the sight-line 18 between the gun barrel 17 of a launch vehicle and the target 13 by a system comprising an optical sight 12 maintained on the target by the gunner, and an infra-red source 21 on the missile tracked by a vehicle tracker 15. The optical sight 12 and tracker 15 are mounted together on the barrel 17 and move as a unit therewith. The tracket continuously determines any difference of the sight-line 18, as determined by sight 12, from the missile course 11. Pulse signals having a duration representing deviation in azimuth and elevation of the missile from the sight-line are supplied by the tracker 15 to a guidance and control computer 22 which equalizes the signals and modifies them in accordance with compensating signals proportional to missile flight time and target motion at right angles to the line of sight sensed by rate gyros 23. These signals are supplied to a modulator transmitter 24 which produces pulse width signals in yaw and pitch and converts them into infra-red signals which are received by a missile receiver 25. The receiver converts the signals into yaw and pitch command information utilized by the flight control 31 to guide the missile through valves 26 with attitude gyros 27 providing pitch roll and yaw inertial reference of the missile. The computer 22 is described in greater detail with reference to Fig. 3 (not shown) and includes a limiter for limiting the error signals. The missile receiver 25 is described in greater detail with reference to Fig. 4 (not shown) and includes a channel separation filter 63 for separating the pitch and yaw signals from one another. The flight control 31 is described in greater detail with reference to Fig. 5 (not shown). The tracker 15 may be as disclosed in Specification 1,459,387.

Title: Fluid impelling devices
IPC: F01C3/06
Filed: 1959-07-03
Abstract: 923,833. Rotary pumps. FLO-MOTIVE CORPORATION. July 3, 1959 [July 7, 1958], No. 22900/59. Class 110 (2). A rotary pump for use in a fuel supply system for an aircraft engine, comprises a casing 23, Fig. 2, having a cylindrical portion 26 housing an electric motor and a hemi-spherical cavity 24 rotatably mounting a rotor 70 driven by the motor. The rotor 70, Fig. 9, is formed with a conical end 71 angled to correspond with an inclined face 106 of a closure plate 91 closing the cavity 24. The rotor is formed with a pair of diametric slots 76, 77 disposed at right-angles to each other in which are respectively mounted vanes 81, 82 which move axially into and out of the slots on rotation of the rotor. The vanes, vane 82 is shown in Fig. 5, is contoured at 96 to closely fit the cavity 24, has a slot mounting a T-shaped sealing strip 89, Fig. 6, urged by a leafspring 92 into sealing engagement with the face 106 and an arcuate notch 84 receiving and straddling the other vane, in this case the vane 81, so that the vanes are allowed to pivot independently of each other in their respective slots. Inlet and outlet passages 107 (not shown), 108 in the closure-plate 91 terminate in sectorshaped ports 109, 110, Fig. 8, disposed in relation to the inclined face 106, so that the vanes pass over the ports and are unloaded during the major portion of their movement into and out of the slots. Shallow rotor pockets 115 between the vanes provide re-circulation of a small quantity of liquid as each passes beyond the outlet port and avoids the possibility of foreign matter becoming lodged between the conical face of the rotor and the face 106. These pockets also prevent the rotor becoming locked and inoperative as the effective discharge vane reaches the leading edge of the outlet port 110. In a modification, the closure plate is provided with a recess 120, Fig. 12, snugly seating a circular plate 121 having a spherical peripheral surface 122 corresponding with that of the cavity 24 and a contoured surface 123 arranged so that an angle a remains constant whilst a vane traverses the quadrant above and between the ports and an angle # remains constant whilst a vane traverses the quadrant below and between the ports so that the movement of the vanes in and out of the slots, takes place wholly over the ported quadrants when the vane is unloaded. In a modified construction of pump, the pump 130, Fig. 19, is supported on legs 133, in a tank with its rotational axis vertical. The outlet (not shown) is from the cavity 24<SP>1</SP> and what was previously the outlet port now constitutes a by-pass port opening into a passage 141 including a normally closed flap valve 142. In the event of the motor stalling the suction from a high pressure pump fitted in the system downstream of the pump 130 lifts the flap 142 so that the aircraft engine may still be supplied with fuel even though the pump 130 is not working. Instead of operating as a liquid fuel pump it may be adapted to function as an air compressor or a pneumatic-motor.

Title: Protein fibre formation
Inventor: HOER RALPH ANTHONY
IPC: A23J3/24
Filed: 1970-05-12
Abstract: 1,269,769. Protein fibres. RALSTON PURINA CO. 12 May, 1970 [19 May, 1969 (2)], No. 22995/70. Heading B5B. [Also in Division A2] Protein fibres suitable for use in the preparation of foodstuffs are produced by a process in which a confined, flowing slurry of a proteinaceous material, suitably of vegetable, animal, microbial or petro-protein, is heated under a pressure and at a temperature sufficient to coagulate the protein, thereby forming fibres in the slurry which emerges through an. orifice into a collecting zone. Preferably the slurry is an aqueous one containing 0.3 to 35% by weight solids, of which at least 70% by weight is protein, which flows through a pipe, whose smallest diameter is between 0À2 and 0À5 inch, under a pressure of at least 50 p.s.i.g. and at a temperature of not less than 165 F. To assist the reaction, which is believed to involve the inter-reaction of protein molecules to form elongated multi-molecular polymers which are oriented into an elongated fibre structure by the shear involved in the flow of the slurry in the pipe, cross-linking agents, suitably salts or hydroxides of bi- or tri-valent metals, and trisodium phosphate may be added to the slurry, the pH of which is preferably adjusted to be in the range 4-11. In examples aqueous slurries of soy protein, from soybean flakes or flour, containing calcium hydroxide, sodium hydroxide or sodium phosphate are treated with sulphuric, citric or phosphoric acid to lower their pH to between 4 and 6 and pumped at pressures of from 200 to 5000 p.s.i.g. and temperatures between 240 and 310 F. through a narrow bore tube to produce protein fibres. Other examples relate to similar treatment of hydrochloric acid-precipitated casein and turkey meat.

Title: Improved apparatus for forming combustible charge for an internal combustion engine
IPC: F02D9/00
Filed: 1958-07-18
Abstract: 827,707. Spray carburetters. GENERAL MOTORS CORPORATION. July 18, 1958 [Aug. 1, 1957], No. 23100/58. Class 7(3) A metering valve 48, Fig. 2, metering fuel supplied under pressure to one or more fuel injection nozzles 60 is controlled in accordance with throttle valve position and engine speed. The metering valve is connected by a link 129 to a lever 136, Fig. 1, which is adjusted through further levers by a cam 162 on the throttle valve spindle and by a rod 176 actuated by a centrifugal governor 172, Fig. 2, At small throttle openings, e.g. up to 10 degrees, the lever 192, on which the centrifugal governor acts through a pin and slot connection 188, is aligned with rod 176 so that the governor has no effect on the metering valve control lever 136. At larger throttle openings a cam 200 on the throttle valve spindle tilts the lever 192 so that the movements of the governor rod 176 are transmitted through lever 192 and pin and slot connection 146 to lever 144 and thence to the metering valve lever 136. At a predetermined speed, adjustable by a throttlevalve-controlled cam 216, the pin 146 enters a circular part 210 of its associated slot to prevent any further adjustment of the metering valve by the governor. The pivot 138 of metering lever 136 is adjusted by a barometric capsule 230 and the pivot of lever 152 is adjusted by a diaphragm 250 actuated by intake pipe suction to produce enrichment at high power outputs. A cold running arrangement, comprising a bimetallic coil 274 and suction operated piston 276, adjusts a lever 278 to cause a member 290 to hold the throttle valve 166 slightly open and a member 304 to move lever 152 to enrich the idling mixture. An abutment 280 on lever 278 also co-operates with an abutment 282 on the rod 154 to limit the opening movement of the throttle valve when the engine is cold. The metering valve is supplied with fuel by a high pressure pump 16, Fig. 2, fed by a low pressure pump 12, a pressure operated valve 30 cutting off the outlet 20 of the pump 16 at starting so that the fuel is supplied direct to the metering valve by the pump 12. The pressure drop across the metering valve is maintained constant by a by-pass valve 98 actuated by the pressures upstream and downstream of the valve. An electrically operated cut-off valve 130 closes the fuel pipe to the nozzle when the engine stops. Passages 66, 68, supply fuel to recesses to lubricate the valve 48, the fuel leaking past the valve being collected and returned through passage 72.

Filed: 1938-08-09
Abstract: 521,093. Moulding by dipping. FORRO, G., and JAKOBOVITS, J. Aug. 9, 1938, No. 23519. [Class 87 (ii)] Hollow articles are made by dipping a mould comprising a core covered by one or more rubber sheaths secured at one end to the core, the article being removed by stretching the sheath to cause it to contract away from the article. In the form shown in the figure a hollow core 10 is covered by a rubber sheath 15 secured at 17 and adapted to be extended by a rod 12 having a conical end carrying a preform 14 of the nozzle of a container 19 produced by dipping. The hollow core covered by one or more rubber or other resilient sheaths may be made of resilient parts adapted to be expanded and contracted by a tapered part movable in the core. In another form, the core covered with a rubber sheath is itself made of rubber and is expanded by tapered member, grooves being provided to minimize friction. In some cases, a hollow core member is made with radial slits, is covered with one or more rubber sheaths, and is expended by an internal sliding member carrying a preform for the nozzle of a tube to be formed by-dipping. In some cases, steam, air, or water is forced between the sheath and the article or core to effect the removal' of the article. Screw threads or other configurations may be formed on the articles by suitably shaping the core or the sheath. The articles may be made of cellulose derivatives, artificial resins &c.
