Title: Improvements in and relating to moulding articles of plastics material
IPC: B29C44/12
Filed: 1963-04-30
Abstract: 1,003,237. Moulding reinforced articles. G. H. BAKER, M. H. BAKER, and R. G. BAKER. April 28, 1964 [April 30, 1963], No. 17044/63. Heading B5A. A reinforced article, e.g. a chair frame, wall panel &c., is formed by expanding beads of plastics material, e.g. polystyrene or polyvinylchloride, in a multi-part mould, the reinforcement being secured by suction, pins, hooks or clips &c. against the mould wall. The reinforcements may comprise pieces, strips or sheets of woven textiles, e.g. hessian or plastics materials, metal, metal foil, glass fibre cloth, leather, sheet rubber, felt, expanded metal sheet, metal gauge, or wire netting. Additional rigid reinforcements, comprising pads to which nails &c. may be anchored in the case of a chair frame, or a door or window frame in the case of a wall panel, may be used, said reinforcements being composed of metal, plastics, or bonded fibrous material &c. In the embodiment shown in the drawings a chair frame is moulded between co-operating mould halves 1 and 2, the mould half 2 being furnished with pins 11 over which is impaled and positioned the reinforcing sheet 12. The beads are introduced through aperture 13, and the steam or hot air needed to perform the expansion through apertures 14. The reinforcements may be coated with a suitable adhesive to ensure adherence with the expanded material.

Title: Improvements in or relating to fuzes for shells, especially for mortar bombs
IPC: F42C15/184
Filed: 1955-06-14
Abstract: 777,781. Projectile fuzes. SALORANTA, A. E. and PURONTO, E. June 14, 1955, No. 17049/55. Class 9 (1). A percussion fuze fitted in the nose of a shell 1 comprises a firing pin 8 which abuts a striker 19 and is surrounded by a locking sleeve or bolt 12 extending into a transverse slide 13 carrying a primer 18, whereby the primer is held out of alignment with the striker. Into the base 3 of the fuze is fitted a booster 7 and an auxiliary booster both of which may contain tetryl. A pin 17 extends through the base 3 to guide the slide 13 around the head of which slide is a spring 5 held in position by a cap 4. The bolt 12 is held in the locking position by a spring 11 and balls 10, and is further secured during transport by a split pin 15 or a screw pin (not shown). The sensitivity of the striker may be reduced by fitting over it a cap 21, the elasticity and rigidity of the cap determining the sensitivity of the striker. Upon discharge of the projectile, due to inertia, the bolt 12 sets back against the action of its spring and releases the balls 10. As the projectile decelerates, the spring 11 moves the bolt forwards thus releasing the slide 13, which is then moved by its spring to the armed position with the primer aligned with the striker. When the shell is rotated, the movement of the slide may be produced by centrifugal force. The firing pin 8 also sets back on discharge of the projectile and is only returned to the firing position after the projectile has left the barrel. Openings 19 may be formed in the striker to equalise the air pressure on the striker.

Abstract: 772,165. Gas turbine plant. BLACKBURN & GENERAL AIRCRAFT, Ltd. June 16, 1955, No. 17460/55. Class 110 (3). In a gas turbine engine comprising an annular combustion chamber into which fuel is projected radially, the fuel is fed to a tube in a hollow rotor shaft to be discharged therefrom into bores in a part, in heat conductive contact with the core of the turbine rotor disc, to cool the same and from whence it passes in countercurrent along the wall of the hollow shaft to radial bores delivering into the combustion chamber. A compressor 3 supplies combustion air to an annular combustion chamber 2 feeding a turbine 4 driving the compressor through a shaft 5. Fuel is fed in the shaft 5 by a pipe 7 and enters a tube 6 which discharges into a plurality of bores 8 in a part 9 in intimate heat transfer contact with the core of the turbine disc 4. The part 9 extends forwardly as a tube 10 which engages the outer wall of the shaft 5 through a seal 11. The fuel returns through the tube 10 and passes through the radial bores 12 into the combustion chamber 2. Specification 686,908 is referred to.
