Patent GB-310083-A (GB)
Title: Improvements in or connected with magneto electric machines
IPC: F02P5/06
Filed: 1928-01-20
Abstract: 310,083. North, R. B., and Allen, A. Massey- Jan. 20, 1928. Driving-arrangements.-In an impulse starter of the compression spring type in which all the parts are enclosed in a housing, the springs, which surround the releasing clicks and their carrier, axe located around the inner periphery of the housing and are constrained against lateral deflection. Also the click-releasing cams are mounted on a member which is secured to the wall of the housing in such a manner as to permit fine angular adjustment for the purpose of controlling the instant of release during the revolution. In the form shown, the housing a is secured to the engine shaft d and its boss e surrounds an extension f of the click-carrier g which is secured on the magneto shaft h. The front of the housing has inturned flanges k preventing lateral deflection of the compression springs m, which springs abut at one end on pins l, seated in the flanges k and the back wall of the housing, and at the other end on arcuate extensions n of the arms' of the click-carrier g. The pins l also form the abutments for the carrier arms when the springs are relaxed, as shown in Fig. 2. The clicks o are pivoted on the arms and the upper one normally falls gravitationally to engage a stop r formed on the face of a disc q which is fixed to the magneto and serves also to close the open face of the housing a. Rotation of the engine shaft and the pins l compresses the springs until one of the cams t, which rotate with the housing a, lifts the click from the stop r and allows the springs to swing the carrier g and magneto shaft h for the starting impulse. To allow control of the instant of release, the cams t may be mounted on a plate s having a number of holes u of a given pitch and the end wall of the housing may have a corresponding series but of different pitch. Thus, by arranging one or other of the two series of holes to coincide for the reception of the connecting screws, a fine angular adjustment of the cam position may be obtained.

Title: Improved means for changing the die in the die-holder of an extrusion press
IPC: B21C23/21
Filed: 1961-01-18
Abstract: 910,634. Extruding. SCHLOEMANN A.G. Jan. 18, 1961 [Feb. 2, 1960], No. 2029/61. Class 83 (4). An extrusion press with an open-ended dieholder 1 adapted to move a die 2 from an operative to an inoperative position, has a diechanging device comprising a first open compartment 5 for receiving the used die from the holder and a second open compartment 12 for a fresh die 16, both compartments being rockable about a common stationary pivot 9, and means 15 for pushing the fresh die into the holder. The latter may be pivoted or slidable horizontally and the die 2 is secured therein by a hand screw 3. When this is released the die falls into compartment 5 against a buffer. A fresh die 16 and a die thrust collar 24, Fig. 2 (not shown), are held in compartment 12 by permanent magnets 17 on a member 15. The spider 6, 7, 8 is then rotated clockwise by a pair of hydraulic cylinders 21 and the new die is pushed into die-holder 1 by member 15 actuated by an hydraulic cylinder 18. Die 2 is still retained in its compartment 5 by a retaining wall 23 and after a return movement of the spider, is removed by a crane. Alternatively, wall 23 may be omitted whereby the die can roll out of compartment 5.

Patent GB-469402-A (GB)
Title: Submarine gun and carriage therefor
IPC: F41A7/08
Filed: 1936-01-23
Abstract: 469,402. Mounting guns on submarine vessels. HOPKINS, N. M. Jan. 23, 1936, No. 2198. [Classes 92 (i) and 92 (ii)] A gun is resiliently suspended by a universal joint outboard of a submarine vessel or other floating platform so that its breech end is immersed in the water which absorbs the shock of recoil. The invention includes means for moving the gun inboard for loading and outboard for firing. The gun elevation may be controlled by hydro-vanes on the breech which cause the elevation of the gun to correspond with the speed of towing through the water. Alternatively, the elevation may be controlled by allowing water to enter or leave a receptacle on the gun. Fig. 11 shows in plan the arrangement of port and starboard guns x, y which are each supported on vertical pivot pins 24 carried by the forked ends of horizontal trunnion shafts 62, the latter being the piston rods of hydraulic jacks 97 which serve to move the guns on slides 115 to the inboard and outboard positions shown. Vanes 37 serve to keep the guns at elevation during towing and vertical vanes 38 serve to check the movement of the guns about the pins 24. Indicators 103, 109 show the positions of the guns in elevation and training respectively. Fig. 2 shows a gun in vertical section. The breech end of the gun which carries the hydrovanes is in the form of a sleeve 28 with closed end 29. The sleeve is slidable rearwards on the barrel 45 for moving the breech-block 47 to the open position shown in Fig. 6 thus permitting the loading of a projectile 271 and powder charges 68 by hydraulically-operated pistons 70, 69 extending through a hatchway in the vessel which registers with an opening in the underside of the casing 28 when the gun is inboard with breech open. The breech is opened by an electric motor 54, Fig. 2, which rotates a pinion 52 on the casing 28 geared to nuts which engage with screws 46 fixed to the gun breech. Current is supplied to the motor from a dynamo 139, Fig. 11, through hinged contact arms 147 which wipe along contact bars 40 on the sleeve 28. Firing is effected by a solenoid 58 acting on a firing pin 56, the circuit through the solenoid being completed only when the breech is closed and the gun is in the outboard position. On firing, the gun barrel with the sleeve 28 recoils relatively to the fixed support 23 against the action of a spring or other brake 43 and against the resistance of the sea water.

Abstract: Delustred polyamide threads, fibres, bristles, ribbons, &c., having a high bulk-elasticity are made by mixing a linear polyamide with polystyrene in an amount of 0.5 to 35 per cent by weight of the polyamide and melt-spinning the composition.  The polystyrene is distributed in the polyamide as microscopically small particles. Mixing is effected by (1) jointly melting the two components, (2) adding one component to a melt of the other, or (3) combining melts of the two components; mixing being performed under sub-, normal- or super-atmospheric pressure in an inert atmosphere.  In examples (1) 10 kg. polycaprolactam (M.W. 15,000) and 1.5 kg. polystyrene (M.W. 180,000) are melted together.  The blend is extruded in ribbon form, comminuted and melt-spun into a mat fibre.  (2) 10 Kg. polyhexamethylene adipamide (M.W. 16,000) and 1 kg. polystyrene (M.W. 110,000) are jointly melted.  The blend is cast into ribbons, comminuted and melt-spun by the grid-spinning process into staple fibre.
