Title: Compression-actuated adjuster for hollow-piston braking systems
IPC: B61H15/00
Filed: 1951-12-10
Abstract: 693,209. Brake slack adjusting mechanism. SOC. GENERALE ISOTHERMOS. Dec. 10, 1951 [Dec. 28, 1950], No. 28902/51. Class 103 (i).  An automatic slack - adjusting mechanism for railway vehicles is arranged within the hollow piston 1 of the brake cylinder. The mechanism comprises a hollow member 4 one end of which is engaged by the outer face of the piston 1. Locked between shoulders at the other end of member 4 are races 5 and 7 which through rollers 6 and 8 respectively may lock a rod 3 to the end of which is secured the brake shoe. The rollers 6 and 8 are separated by distance pieces 9 which are normally urged by a spring 10 so as to engage rollers 8 and races 7. Also contained within the hollow piston is a casing 11, one end of which has a shoulder engaging the member 4, the other end being rigidly secured to the inner and outer socket members 12. A relatively strong spring 13 is disposed between the end of member 4 and the inner socket member 12. The members 12 contain a further locking race and roller set 16, 17 engaging the rod 3. A fixed check member 19 is provided ahead of the socket portion 12 to engage same when the outward stroke of the piston has reached a desired limit. Operation is as follows. Admission of compressed air to the brake cylinder drives the hollow piston 1 to the right and carries with it the member 4 and the rod 1. Due to the action of the slack take-up race 16 and its rollers 17 the member 4 and rod 1 are rigidly connected so as to transmit the force to the brake blocks. The action of races 5 and rollers 6 prevents any lengthening of the two parts under tensile load. If the adjuster is too short the shoulder on outer socket member 12 will engage the cheek member 19 before the shoes are applied to the wheels. As a result the casing member 11 is held axially while the hollow member 4, pushed by piston 1, continues its forward stroke with rod 1 compressing spring 13, the rollers 6 being operative for locking purposes. On release of the brake, the rod 3 cannot recede since it is held by rollers 17 but the member moves back relatively to the rod 3, following the piston 1 under the action of the spring 13, rollers 8 being in non-locking condition due to spring 10 being compressed. As soon as the socket 12 leaves the cheek member 19, the spring 13 is decompressed, rollers 8 and races 7 relock and the adjuster is set in its new length. If the adjuster had been tooling the shoes would engage the wheels, before the socket 12 had engaged the member 19. The rod 3 is therefore held but the member 4 continues its movement by compressing spring 13. Re-locking of the members 3 and 4 takes place on release as soon as the compression of the spring 13 is relieved.

Title: Improvements in and relating to methyl polysiloxane compositions
IPC: C08L83/04
Filed: 1945-11-06
Abstract: A composition comprises a dimethyl silicone gum, having a methyl to silicon ratio between 1.98 and 2 mixed with a soluble high molecular weight methyl polysiloxane resin having a methyl to silicon ratio between 1 and 2 and preferably between 1.3 and 1.7. The silicone gums are prepared by treating liquid dimethyl silicones with a hydrated metal halide, e.g. ferric chloride hexahydrate, suitable methods being described in Specifications 592,456 and 594,481.  The soluble resins are described for example in Specifications 542,655 and 572,230.  The silicone gum may be soluble in inert aromatic hydrocarbons and with a methyl to silicon ratio of 2, or insoluble with a methyl to silicon ratio of at least 1.98 but less than 2. Soluble gums are mixed in solution with a solution of the polysiloxane resin, while insoluble gums are milled with the resin using milling rolls, colloidal mills or a Banbury mixer.  The soluble gums should be washed before dissolving them to remove metal halide or the solution should be prepared by the method of Specification 594,508.  The invention is particularly applicable to high molecular weight resins of the type described in Specifications 585,628 and 592,552.  One method of preparing the composition is to work the silicone gum on milling rolls at room temperature or at 70-80 DEG C., and slowly pour on to it a toluene solution of the polysiloxane resin.  The mixture is then milled until homogeneous.  The product can be dissolved in toluene mineral spirits or solvent naphtha, to form a varnish.  Curing agents may be added to the varnish, e.g. one as described in Specification 597,834.  Benzoyl peroxide may also be added as described in Specification 592,018.  The solutions are useful for coating or impregnating particularly of glass or asbestos tapes or fabrics, the composition being cured by baking at 200-250 DEG  C.  The impregnated materials are useful for electrical insulation.  The solutions may also be employed in the manufacture of gaskets, and gas-impervious sheeting.
