Title: Coated fabrics
IPC: C08J5/06
Filed: 1964-04-17
Abstract: A textile material is coated with a vulcanized ethylene-propylene-copolymerizable diene terpolymer rubber (EPDR), the rubber being adhered to the textile by a deposition on the textile, in an amount of from 0,1-4% by weight of the textile, of a partially-reacted resorcinol-formaldehyde resin applied to the textile from an aqueous solution which may contain up to four parts by weight of natural and/or synthetic rubber or thermosetting acrylic polymer per part by weight of resin, and the treated textile being dried prior to coating with and vulcanization of the terpolymer rubber.  The textile material may be dipped in the adhesive solution, and the amount of solids deposited may be controlled by squeezing the solution out of the textile, e.g. by rolls, or by blowing with an air blast.  The textile is dried and vulcanizable EPDR stock is coated thereon, for example, by calendering, followed by vulcanization.  The textile material may be any conventional fabric used to reinforce rubber articles, e.g. cotton, rayon, nylon or polyester, and it may be in the form of cord or woven fabric, mono-filament or multi-filament cords; plied yarns, or staple fibre.  Suitable co-polymerizable dienes include dicyclopentadiene, methyl cyclopentadiene dimer, 1-4-hexadiene, 11-tridecadiene, and 1,9-octadecadiene.  Specified synthetic rubbers are SBR, butadiene-vinylpyridine rubber with or without added styrene, butyl rubber latex, EPDR latex, or mixtures thereof.  The thermosetting acrylic polymer may be a copolymer of methylacrylamide and methacrylic acid.  Conventional compounding ingredients, e.g. accelerators, stabilizers, antioxidants and curatives, may be included in the adhesive solution.  After drying the adhesive solution on the textile material at a temperature of at least 250 DEG F., the EPDR rubber stock is contacted with the adhesive-treated surface of the textile.  The EPDR rubber stock is compounded for vulcanization using conventional curatives and accelerators, and optionally antioxidants, preservatives and fillers.  The EPDR may be oil-extended and blended with saturated EPR (ethylene-propylene copolymer rubber).

Title: Improvements in or relating to single chamber compressed air brakes
IPC: B60T15/30
Filed: 1928-06-05
Abstract: 318,533. Hildebrand, W. June 5, 1928. Fluid-pressure.-In single chamber compressed air brakes comprising a primary and secondary valve S<1>, S<2> both controlling brake application and influenced by the pressure in the train pipe L, one mainly for filling and the other mainly for exhausting the cylinder C, the valve S' is further influenced bv auxiliary reservoir pressure, and the valve S<2> is also influenced by brake cylinder and a constant pressure in a chamber A, which opens this valve when brake cylinder pressure falls, so that loss of brake cylinder pressure is automatically compensated for. Fall of pressure in the train pipe L causes movement of pistons K<1>, K<2> of the two valves to close the exhaust passage e, V<1>, O, O<1> and to supply pressure-fluid to the pipe e and the brake cylinder from the auxiliary reservoir B past slide valve S' and also through a pipe f and a valve V<2>. The increased brake cylinder pressure acts on a piston K to re-close the valve V<2> and maintain the brake adjustment. If the brake cylinder pressure falls owing to leakage, the valve V<2> is reopened to maintain the pressure at the level fixed by the pressure in the train pipe. Increase of train pipe pressure to release the brakes opens the exhaust valve V<1> and the slide valve S<1> connects exhaust passages O, O<1>. The consequent reduction of brake cylinder pressure on the piston K re-closes the valve V<1> and thus a graduated release is obtained. A transfer chamber U is controlled by the valve S<1>. In a modified construction, the chamber A is filled directlv from the train pipe past the piston K<2>, and the exhaust outlet is not controlled by the valve S<1>, being located in the housing of the valve S<2>. Reference has been directed by the Comptroller to Specification 295,988.

Title: Improvements in or relating to solid-state image intensifiers
Filed: 1955-06-07
Abstract: 783,812. Colour television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 7, 1955 [June 10, 1954], No. 16343/55. Class 40 (3). [Also in Group XL (a)] The layer 7 (Fig. 1) between the photo-conductive layer 6 and the electroluminescent layer 8 of a solid plate image intensifier is of powdered magnesium oxide or titanium oxide. A glass support 11 is coated with a thin transparent electrode layer 2 of tin oxide having a thickened edge 3 to which a ter. minal wire is connected, followed by a further transparent conductive layer 5 and a photo-conductive layer 6, 100 microns thick, of selenium, germanium zinc sulphide lead sulphide, lead monoxide or lead selenide. On the other side of the intermediate layer 7 are the electroluminescent layer 8, a transparent electrode 9 with thickened terminal part 11 and a glass plate 10. The whole is housed in awooden frame 13and kept together by resilient rubber strip 14. An insulating transparent layer 100Á thick of mica glass, foam glass, melamine or nylon may be provided either between the photo-conductive layer 6 and its electrode or between the electroluminescent layer 8 and electrode layer 9. An alternating voltage is applied to the electrodes. Two screens may be used in cascade, the image being projected by lenses (Fig. 3, not shown); or three screens may be contiguously mounted with common electrode layers between them, one pole of the voltage source being connected to the first and third electrode and the other pole to the second and fourth electrodes (Fig. 4, not shown). The intensifier screen may also be mounted between the luminescent layer and the end wall of a cathode-ray tube or an electron microscope (Fig. 5, not shown). Colour images may be amplified by mounting identical multi-line colour filters 61, 62 adjacent the electrode layers of the photo-conductive and electroluminescent layers 66, 68 respectively, Fig. 6, or alternatively at a distance therefrom. The filters may have different colours for corresponding lines for colour correction or colour reversal purposes. Instead of using colour filters, the electroluminescent screen may be composed of lines or dots of different materials with red-green and blue responses. The materials are respectively copper-activated zinc selenide and two copper-activated zinc sulphides. The screen is scanned by a light spot from a C.R.T. which is colour modulated to the line pattern of electroluminescent layers (Fig. 7, not shown). Alternatively the photo-conductive layer may be of line or dot pattern of materials with different colour sensitivities, e.g. cadmium sulphide, zinc sulphide and a mixed crystal thereof. A colour picture is projected on to the photo-conductive layer and the resultant electroluminescent image modulated by the colour information is projected on to the photo-sensitive electrode of a television pick-up tube (Fig. 8, not shown). Three separate intensifier screens each with a different colour filter may be utilized and combined to give a colour picture.
