Title: Improvements in internal combustion engines using cam driving gear
IPC: F01B3/04
Filed: 1931-12-08
Abstract: 391,529. Driving-gear ; four-stroke engines. FINLAY, R. N., 66, Eglantine Avenue, Belfast. Dec. 8, 1931, Nos. 33989/31 and 24053/32. [Class 7 (ii).] A cam driving-gear consists of two concentric cylinders 6, 8 with wave-like ridges 5, 7, these ridges being engaged by rollers 3 carried by piston-rods 1. The rods are hollow, and spring cushions are provided for the mounts which carry the rollers ; these are in the form of truncated cones, whose imaginary apices lie on the axis of the cylinders. The rollers are reciprocated by pistons working in doubleacting two-stroke cylinders, or (as shown) by pistons in pairs of four-stroke cycle cylinders arranged in tandem ; the power cylinders have their axes arranged around a central cam shaft. The concentric cylinders 6, 8 drive the cam shaft 11, which is adjustable to vary the timing of the valves 23. These act both as air inlet and exhaust valves when the engine works with compression ignition. The valves are arranged to retain in the cylinder for each succeeding cycle some of the products at low load. The contour of the ridges is designed to give two or more complete cycles for each revolution of the cylinders 6, 8. In a modification, a water-cooled explosion engine is described. Pipes.-A combined air-admission and exhaust pipe 39 for each cylinder end has a deflector surface 40 for diverting air towards the valve 23, and a similar surface 41 to guide the products into a manifold 25. Pistons, cooling.-The hollow piston-rods 1 allow a flow of cooling-air through the pistons, this air being collected by scoops 38 on the ends of the cylinders 6, 8. Pipes 33 form outlets for this cooling-air. In the explosion engine water-cooling is used for the pistons.

Title: Pneumatic control device
IPC: F15C4/00
Filed: 1964-08-20
Abstract: 1,016,558. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. Aug. 20, 1964 [Oct. 3, 1963], No. 34107/64. Heading G3P. A pneumatic controller comprises a diaphragm 60, Fig. 1 (not shown) responsive to a controlled condition and operative on a flapper 118 coacting with a nozzle 42, a relay valve 72 governed by the flapper and controlling an output pressure at 80, and a feedback diaphragm 98 responsive to the output pressure and also operative on the flapper. The controlled condition may be temperature, pressure, humidity or, as shown, fluid flow for which the pressure upstream and downstream of a grill, heating or cooling coil, or a damper in an air conditioning duct act on opposite sides of the diaphragm 60 and the output port 80 leads to a damper motor. The flapper 118 normally engages the nozzle and is biased away therefrom by a spring arrangement 126 which has a set point adjustment 166, 168 and a portion 142 which engages the flapper and is connected by a bracket 146 with the diaphragm 60 and by a plunger 102 with the feedback diaphragm 98. Any change in force applied by the diaphragm 60 to the spring portion 142 results in movement of the flapper to alter the pressure in an annular chamber 36 which is fed from a supply port 46 through a passage 48, filter 50 and restriction 55. The change of pressure in the chamber 36 causes movement of a diaphragm 38 to actuate the relay valve to connect the output port 80 to supply 46 or exhaust 82 until the output pressure acting on a diaphragm 76 balances the pressure in the chamber 36. The output pressure also passes through a restriction 94 to the feedback diaphragm 98 which acts on the spring portion 142 in opposition to the diaphragm 60. The degree of feedback is adjusted by a needle valve 114 controlling a vent 104.

Title: Improvements in or relating to electrically operated indicating mechanisms
IPC: G08B5/30
Filed: 1931-12-09
Abstract: 383,761. Two-position indicators. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and ROSE, W. R., of General Electric Co., Stoke, Coventry. Dec. 9, 1931, No. 34137. [Class 40 (i).] In a two-position indicator wherein the indicating member is operated by the pivoted armature of a pair of electromagnets, the armature co-operates with the indicating member through the intermediary of a spring which acts also to retain the indicating member and the armature at either of their extreme positions. As shown in Fig. 3, the armature 13 carries a spring 20 of substantially straight wire which engages under slight downward tension a forked member 17 on the shaft 24 of the indicating disc 18. The disc and the armature are thus retained in one of their extreme positions against a stop e.g. 25 under the action of the spring. When the armature is rocked into its other position, the spring 20 rotates the forked member and is bent during movement until it reaches a " top dead-centre " position, whereafter it assists the armature to move the disc, the assembly finally coming to rest with the forked member resting against the stop 23 and being urged to retain this position under the action of the spring. The indicating member may be painted black with a white diametrical stripe, and the assembly may be mounted in a cylindrical case having a transparent front. In a modified form the end of the spring 20 co-operates with a vertical slot in the back of a slidable indicating member. Fig. 4 shows the operating circuits of the indicator. Operation of key K to the right energizes coil R which throws over the armature. The armature operates contact r<1> which opens the energizing circuit and prepares the circuit of the other coil.

Title: Improvements relating to the manufacture of glue
IPC: C09H3/02
Filed: 1947-12-24
Abstract: Glue-containing liquids, produced by boiling bones, hides, or fish in water, are treated to separate the glue by adding tanning-agents in insufficient quantity to precipitate the glue, salting-out by the addition of electrolytes, preferably of a neutral character, e.g. glauber salt, magnesium sulphate, or salt, removing the precipitate and resolubilizing it by treating with a substance capable of forming an insoluble compound with the tanning-agent.  The insoluble compound is in finely-divided condition and relatively small quantity so that it has no deleterious action on the glue.  If alum is used as the tanning-agent, phosphates or soda may be used as precipitating agents, sufficient soda being added to produce a basic aluminium salt.  The liquid drawn off may be used again with the addition of sufficient salt to bring it to the necessary concentration.  In the case of liquid obtained from the extraction of whale and herring oils, the salting-out may be effected by means of potassium salts and the resulting liquid treated to produce a residue suitable for use as a fertilizer.

Abstract: 874,887. Injection moulding footwear. BRITISH UNITED SHOE MACHINERY CO. Ltd. Nov. 13, 1957 [Nov. 13, 1956; Nov. 1, 1957], Nos. 34600/56 and 34113/57. Class 87(2). A machine for injection moulding plastic soles on to footwear uppers or for moulding complete articles of footwear from plastic materials comprises a number of moulds M mounted on a carrier 20 by means of which they are moved successively into position adjacent an injection mechanism, each of the moulds having a pair of side mould members M 1 , M 2  one movable towards and away from the other, and a movable sole mould member B, which are arranged with respect to a foot form F so as to provide the required mould cavity. The foot form F is movable from its operative position to one intermediate of the side mould members M 1 , M 2 , to facilitate removal of a shoe from the form. The side mould members M 1 , M 2  are mounted on supporting members 50, 52 which are hingedly connected to a supporting member 56 for the sole mould member B. The moulds are revolved intermittently by the carrier 20 between a loading station, a mouldclosing station, an injection station, and a mould-opening station. Each of the upper mould supporting members 50 has a mould opening and closing member in the form of a pin 102 which can be gripped by a pin-embracing member 104 and a tongue portion 108 pivotally mounted on a pin 110. The tongue portion 108 forms part of a carrier member 112 supported on a parallel linkage system comprising the pairs of links 120, 122. The member 104 is swung to its pin-embracing position by the cam 160 acting on the plunger 118. Upward movement of the rack 148, when fluid under pressure is admitted below the piston in cylinder 154, will swing the links 120, 122 clockwise to the positions they occupy in Fig. 4 thus closing the mould box. On arrival at the injection station, the mould box may be latched by a pair of latch members 310, each of which is carried by a link with which it forms an inverted toggle arrangement. The toggles are " made " by rearward pressure on the upper portions 326 by a piston device (not shown), the portions 320 engaging beneath the blocks 322. During the injection of the plastic, the mould box is firmly clamped in position by piston rods 346, on which are freely mounted bearing blocks 348, being thrust downwards to deflect the table 20 until it is firmly seated on the bearing blocks 340, 342. For unlatching the latch members 310 prior to opening the mould boxes, a member 350 is pivotally mounted on arm 354 so as to engage an abutment 351 on the upper end portion 326 of latch member 310 when the plunger 372 in cylinder 380 is moved forward, thus breaking the toggle linkage referred to above. A fluid pressure power unit and associated circuit and control means automatically effect a power cycle of operation of the mechanisms at the various stations of the machine. Specifications 704,884, 831,192 and 831,193 are referred to in the first Provisional Specification.
