Abstract: 1,175,913. Rotary disc valve. STOCKPORT ENG. CO. Ltd. 8 July, 1968 [8 June, 1967], No. 26474/67. Heading F2V. In a multiple-way, manually-operable disc valve, which has a centrally located supply port and, circumferentially disposed there around, an exhaust port and three working ports (4 and 6, 5, 7, 8 respectively, Fig. 1, not shown), control of flow is achieved by a rotor 11 which has formed therein a central bore which communicates with the supply port via duct 15, a longitudinal bore 19 which communicates with the central bore and is disposed for alignment with the working ports, and an arcuate recess 29 which at all times communicates with the exhaust port, the central bore housing a spring-biased valve member 22 which is movable away from its seat 17 by a rod 28. In operation, the cam surface of a handle (12, Fig. 1) is spring- urged into engagement with the rod 28, although the spring bias is insufficient to unseat member 22, and the handle is disposed in one of four recesses (35 to 38, Fig. 1), which are formed in the valve body and correspond to positions in which bore 19 is aligned with one of the three working ports or with an unported part of the stator, as shown, the latter position corresponding to a neutral state of the valve. With the bore 19 aligned with one of the working ports, flow from supply to that port is effected by depressing the handle, and hence rod 28, and maintaining it in that position, the remaining ports being simultaneously connected to exhaust. To change the working port, the handle is lifted against its bias, as a result of which member 22 becomes seated, and arcuately moved over the body top surface until it engages one of the recesses which correspond to the desired port. Of the four body recesses, one may be formed with a horizontal extension into which the handle may be moved, subsequent to being depressed, in order to retain the valve in its open condition.

IPC: C09J7/32
Filed: 1963-07-05
Abstract: A substantially non-curling gummed sheet of the water-remoistenable type is made by dissolving water-reactivatable gum in water to form a water solution of gum, dissolving in a solvent a binder which is substantially insoluble in water, dispersing dry particles of water-activatable gum in the binder solution, the dry particles of gum being not readily soluble in the solvent and the binder solution being incompletely miscible with the water solution, dispersing the water solution in the binder solution to form an emulsion comprising globules of water solution of gum in addition to the particles, coating the emulsion on a sheet, and drying the coating while permitting the globules to coalesce partially to form a honeycomb structure of partially coalesced pieces of gum, the binder preventing the pieces coalescing completely.  After the water solution is dispersed in the binder solution and before the coating is dried, the particles absorb water from the water solution and the particles partially coalesce when the coating dries.  The binder may be resinous and the ratio of gum to binder may be at least 10 : 1 by weight, e.g. of the order of 30 : 1.  The binder solvent may comprise at least 25% of the liquid by volume in the emulsion. The binder solvent may be a mixture including a substantially water-immiscible solvent and a solvent having a limited miscibility with water.  The binder may be selected from vinyl ester copolymer, polyvinyl chloride, butadiene-styrene copolymers and polymers of acrylic esters, e.g. vinyl acetate copolymerized with a small proportion of crotonic acid.
