Patent GB-727321-A (GB)
Title: Coated flexible sheet materials
IPC: D06M15/564
Filed: 1952-02-18
Abstract: A coating for a flexible sheet material comprises a blown layer of a polyisocyanate-modified polyester.  The polyester, which may be prepared from adipic acid, hexane-triol, and butylene glycol in various molar proportions, may be reacted with toluylene or hexamethylene diisocyanate or a triisocyanate obtained by reacting one of these with hexane-triol.  The blown layer of polyisocyanate-modified polyester is formed from a mixture containing the polyester, the polyisocyanate, and a small amount of water, or of a material which will deliver its water content when a certain temperature is reached, e.g. silica gel or crystallized organic or inorganic salts containing water, e.g. aluminium sulphate.  The silica gel or the crystals may be coated with paraffin, dodecyl amine, or synthetic wax to inhibit premature release of water.  The velocity of the reaction between the polyester and the polyisocyanate may be retarded by adding plasticized polyvinyl chloride.  Pigments such as titanium dioxide, cadmium or iron oxides and solvents such as ethyl and butyl acetate may be added.  Examples 5 and 6 describe further porous layers made from a polyisocyanate-modified polyester composition in which finely-ground sodium chloride or sulphate has been incorporated.  The soluble salt is removed by washing with water after the layer has dried.  Example 6 describes a coating of polyvinyl chloride plasticized with dioctyl phthalate made porous by the addition, and subsequent reaction on heating, of a mixture of equal parts of tetramethylene dinitroso dimethyl urethane and dicyano diamide oxalate.

Title: Pneumatic-Hydraulic Multi-chamber Servo Brake Actuation Device
IPC: B60T13/565
Filed: 1967-01-30
Abstract: 1,157,861. Pneumatic-hydraulic brake cylinders. ERNST HEINKEL A.G. 30 Jan., 1967 [1 Feb., 1966], No. 4516/67. Heading F2F. A pneumatic-hydraulic multichamber servo brake actuation device comprises at least two pneumatic pressure cylinders with diaphragm type pressure pistons 10, 17, Fig. 1, secured to a central pressure body 5 acting on a main hydraulic piston 402 in which the working chambers E, C of the cylinders are interconnected by air passages arranged within the pressure body which presents a valve seat 205 associated with the passages and co-operative with an obturator member constituted by the central portion of one of the diaphragm type pistons. In the inoperative position shown in Fig. 1, the valve 7, 205 is closed to confine ambient pressure in chamber A. Engine-produced vacuum is transmitted via passage 40, chamber F, passage 53, chamber D, passage 54, chamber B, passages 55, 56 into chambers C and E. Manual operation of the brake pedal initially moves ram 1, control piston 2 and feeler piston 4 to the left. At the same time the pressure body 5 is moved by spring 6 to act on the hydraulic piston 3, thereby pressurizing the hydraulic fluid. This purely manual displacement continues until both valves 7, 205 and 7, 9 are closed, Fig. 2 (not shown), to separate chambers B, C and E from chambers D and F, the chambers B, C and E remaining subject to the vacuum. Continued manual operation now overcomes spring 6 to open valve 7, 205 to admit ambient air from cavity A via passage 55 into chamber C where it presses the piston 10, Fig. 3 (not shown), to the left, thereby causing the pressure body 5 to move the hydraulic piston 3. Ambient air is also communicated via passage 56 into chamber E where it acts on piston 17, thereby increasing the force on pressure body 5 and piston 3. Hydraulic pressure acts on feeler piston 4 and is transmitted via control piston 2 and ram 1 to the brake pedal so that the driver receives a directly proportional indication of the actual braking effort exerted. When the brake pedal is released, springs 43 and 6 force pistons 10 and 2 back to the inoperative position of Fig. 1. Vacuum passage 40 has a non-return valve (not shown).
