Abstract: 590,934. Trunks or pants. CORAH & SONS, Ltd., N., and ARKINSTALL, T. April 26, 1945, No. 10475. [Class 141] Trunks and like garments for male wear are formed with a front panel 4a of generally triangular formation, which has darts 7 arranged as shown to give a pouched effect to the crotch portion of the panel. The panel is sewn at 9 to the front part 4b of the garment, and at its other side is partly free from the other front part 4c to leave a fly opening offset from the centre line'of the panel. The panel and part 4c may overlap, or the part 4c may have a flap 10 to underlie the opening. The panel may be of double thickness, the waistband may be elastic, and rear portion of the garment may be cut higher at the centre of its top edge to give fullness to the seat. For bathing trunks, the fly opening may have a sliding clasp or other fastener. Specification 574,426 is referred to.

Title: Reinforced flexible conduit
IPC: B29D23/18
Filed: 1960-03-28
Abstract: 892,654. Flexible conduits. DAYCO CORPORATION. March 29, 1960 [April 20, 1959], No. 11073/60. Class 99(2). A reinforced flexible conduit, Fig. 8, particularly for use in vacuum cleaners, respiratory devices or cooling systems, comprises a helical reinforcement 11 having disposed concentrically therewith a tube 15 of elastomeric material and an unstressed, longitudinally stretchable tubular fabric reinforcing member 17. A further tube 18 of elastomeric material may be inserted on the member 17. The tubes 15, 18 may be of vinyl or polyethylene. The reinforcement 11 consists of plastic coated wire. The member 17, in the form of a knitted, woven or braided stockinet, may be made of cotton, rayon, nylon, acetate, acrylic or polyester fibres or of a mixture of these fibres. The fibres may be treated with a vinyl compound. As shown in Fig. 3, the conduit is made by winding the reinforcement 11 on a perforated mandrel 12, introducing the mandrel in a vacuum box 13, as described in Specification 867,836, in which the tube 15 has been expanded and releasing the vacuum force so that the tube is made to closely envelop the reinforcement. The tube 15 may be coated with an adhesive and the stockinet 17 is then pulled over the assembly which is again introduced in the vacuum box for the application of the tube 18 thereon. The conduit is then placed in a hot air curing oven 19, Fig. 6, where corrugations are formed by applying a vacuum to the hollow interior of the mandrel 12 through a vacuum line 22 connected thereto. Depending on the temperature and also whether adhesive has been applied to the tube 15 or whether the stockinet is coated completely or on one surface, the tubes and the stockinet are bonded to each other and to the reinforcement 11 only at the areas of contact between the coils and the stockinet, or a complete bond occurs along the contacting surfaces of the tubes and stockinet, or again all components are fused into a unitary mass. In other forms of the invention the tube 18 is dispensed with and the stockinet 17 is applied either over the tube 15 or directly over the reinforcement 11. In an alternative method of manufacturing the conduit of Fig. 8, the stockinet 17 and the tubes 15, 18, Fig. 14, are placed on the mandrel 12 so that their ends extend beyond the ends of the reinforcement 11 and air is blown by means of an air hose 26 into the interior of the mandrel so as to raise the assembly of tubes and stockinet from the mandrel, allowing them to shrink until their ends are in alignment with the ends of the reinforcement. Specifications 761,212 and 782,541 also are referred to.

April 8,1930, No. 11190. [Class 46.] A filter for liquid fuel systems, such as those of automobiles, aircraft, and motor-boats, comprises a cylindrical filtering element arranged in an outer casing which is closed at one end and has apertures for the entry of the liquid in the side of the casing, said casing being provided with a valve which closes to prevent the escape of liquid when the filter element is removed from its position or released. Liquid from a tank K, Fig. 1, passes through apertures G into a tube E, attached to an adapter D screwed into the base of the tank, and through filtering- material C on a perforated tube A from the lower end of which the liquid is discharged. When a cock or connection B is unscrewed from the adapter, as for the cleansing of the filter element, a valve H is forced by a spring I upon a seat F and prevents escape of the liquid. In a modification a ball, supported on the upper end of the tube A and tailing under gravity when the tube is removed, takes the place of the valve member H. Fig. 3 shows the arrangement of the device in a casing M connected in a pipe line N, L. In this case the valve H closes when the pipe L is unscrewed from the adapter D.

In a dry cooling tower in which ambient air is drawn over tubular heat exchange elements 13, thereby cooling a liquid such as water flowing through the elements, the effective surface area of the elements 13 is reduced when necessary to prevent overcooling, by providing as shown in Fig. 3 hinged flaps 17 which are moved to blank off some of the heat exchange surface from the air stream and permitting ambient air to be drawn into the lower density air within the tower and thereby decreasing the draught of the tower. In Fig. 4, (not shown), two flap members 30, 31 are hinged together at 32 and enable larger surface areas to be blanked off. The flap members are operated manually or automatically by means responsive for instance to the water outlet temperature. The flaps may be arranged above the elements 13 and used in both natural and forced draught cooling towers. The cooled water is used in a direct contact condenser to condense exhaust steam from a turbine 34, Fig. 1 (not shown).

Abstract: 567,120. Valves. KIDDE CO., Ltd., W., and BARBER, F. July 13, 1943, No. 11381. [Class 135] A valve device, particularly applicable for use in fire extinguishing systems and emergency flotation systems, is held to its seat by a frangible disc adapted to be fractured by a sudden blow. As shown in the Figure, the frangible disc 7 of brittle material, such as cast iron, pottery, glass, or thermo-plastic material, is adjustably supported by a screwed ferrule 8 and engages a strut 6a on the valve member 6 to hold the valve member in contact with its seat 5. A hollow plunger 9 housed in the ferrule 8 is formed with a striking head 9a adapted to be struck by a hammer or otherwise to fracture the disc and permit the valve to be fully opened by the pressure of the fluid. The disc may be fractured by an explosive charge behind it, the high pressure developed either directly breaking the disc or forcing a small projection against the disc. In a modification, the strut is guided with a socket slidable on a guide spindle secured to the plunger.
