Abstract: 949,768. Brake cylinders. GUSTIN-BACON BRAKE CO. Oct. 5, 1962, No. 37809/62. Heading F2F. A vehicle brake-operating mechanism comprises a cylinder 10 containing a piston 31 and, at one end, a flexible diaphragm 18 and a brake-operating rod 21, passing axially through the piston and cylinder and movable by either the piston or the diaphragm, the diaphragm being moved during the normal application of the brake by fluid pressure through an inlet 50 and the piston being normally retained in the retracted position by fluid pressure through an inlet 49 but moved, on failure of the fluid pressure, by springs 29, 30. A vent 51 enables the diaphragm to move and as it does so it presses on a pad 20 on the end of the rod 21, which is pivoted to an operating arm 23 for the vehicle brake. The fluid pressure through the inlet 49 is the same as that through the inlet 50 and is sufficient to keep the piston 31 retracted against the force of the springs 29, 30. Movement of the piston 31 on removal of the fluid pressure is transmitted through a sleeve 43 to a disc 44 held on the operating rod 21, whereby the brake is applied through the force of the springs 29, 30. These springs seat on the underside of a metal annulus 24 which is bolted to the wall of the cylinder. When fluid pressure is cut-off from the inlet 50 the operating rod 21 is retracted and the diaphragm 18 returned to its normal position by springs 38, 40.

Title: Process for the treatment of shaped structures of polymeric materials
IPC: C08J7/12
Filed: 1958-12-01
Abstract: The surface properties of shaped structures, particularly films, of organic polymeric thermoplastic materials are improved by treating the materials with boron trifluoride, and preferably with boron trifluoride and an oxidizing agent.  The boron trifluoride, with or without the oxidizing agent, may be applied as part or all of a gaseous mixture or the boron trifluoride may be applied first, followed by the oxidizing agent.  The proportion of boron trifluoride in the total of boron trifluoride and oxidizing agent used, either in a gaseous mixture or as part of the sequence treatment, may vary from 0.1 to 98% by volume. Treatment with a dry gaseous mixture comprising both boron trifluoride and an oxidizing agent is preferred.  Oxygen or air is preferred as oxidizing agent, but ozone, chlorine, oxides of nitrogen, or vapours of peracetic acid, perbenzoic acid or hydrogen peroxide may be used.  The oxidizing agent preferably comprises at least 2% by volume of the gaseous mixture.  Specified polymers include homopolymers and copolymers of vinyl halides, vinylidene halides, ethylene, including chlorinated and chlorosulphonated ethylene polymers, acrylonitrile, polyethylene terephthalates and polyamides.  Many copolymer components which may also be used are specified.  In an example, a web of transparent polyvinyl fluoride film continuously conducted through a glass-walled chamber is treated at 20-25 DEG  C. with a mixture of 33% of boron trifluoride and 67% of oxygen fed continuously into the chamber, the contact time of the film and the mixture being about 15 seconds.  The treatment improves the adhesion of films to themselves, to metal sheets and to printing inks without impairing their resistance to weathering.  Treated polyvinyl fluoride film is more readily metallized. Specifications 578,079, 605,445 and U.S.A. Specifications 2,177,627 and 2,419,008 are referred to.
