Filed: 1942-02-18
Abstract: 581,764. Tanks. HEWITT RUBBER CORPORATION. Feb. 18, 1942, No. 2191. Convention date, May 26, 1941. [Class 69 (i)] - Flexible-walled fuel, oil or like tanks for aeroplanes &c. are made by applying layers of sheet material on the exterior of a suitably shaped hollow, breakable building form, securing the layers together, breaking the form and removing the fragments thereof through an opening in the flexible material. The form may have suitable reinforcing members and may be built of one or more layers, and of one or more materials such as paper, paper pulp, gypsum, Portland cement, clay, ceramics or resinous plastic materials; the form may be cast in, or built up on, a fired clay mould, one end of the form being left open and subsequently closed by a separate wall. The forms may also be built in one,piece or, as shown, be made in sections such as 10, 11, 12, with hand holes 14 therein, and openings 15, 16, 17, to receive gauge, inlet or vent &c. fittings ; the sections may be connected by bolts &c. 22 passing through wood &c. cross-bars 20 nailed &c. to the open ends of the sections. If the tanks are to be provided with baffles, the latter may be built up of a number of plies to form a crosswall 25, Fig. 3, with one or more flanges 26 which may be reinforced by fibre &c. strips 27 and are fitted over the reduced ends of the form sections. The baffles may be provided with one-way flap &c. valves, filling tubes, or vent or pressure-equalizing pipes. The tank may then be constructed by first applying to the form, previously coated with soapstone, tale, &c., a layer of fabric impregnated with material, such as synthetic rubber, inert to oil etc.; the layer may be formed of separate pieces with their edges cemented together and is cemented &c. to the baffles. Fittings, such as hand hole flanges 35, Fig. 7, or outlet fittings 38, Fig. 8, are secured to this layer, before or after it is applied to the form, as by cementing fabric strips 36, 39. Alternatively, the layer may be formed by dipping the form into a suitable solution, or be built up by spraying, painting, &c. Further layers of material, which may be self-sealing, are then applied to the first layer, after which the form is broken by hammering, pressure, &c., if necessary after softening with water &c., and the parts thereof removed through openings in the tank ; the inner wall of the tank may then be coated with material inert to oil &c.

Filed: 1944-02-08
Abstract: Organo-silicon resins having improved ageing and curing characteristics and which may be used as adhesives and as heat resistant insulators for electrical coils are obtained from intermediate condensates prepared by hydrolysing one or more organo-silicon halides having not more than two alkyl, aryl, alkaryl or aralkyl radicals and not more than three halogen atoms as substituents, or mixtures of such halides with a silicon tetrahalide, by dissolving the intermediate condensate in an inert solvent and heating the solution in contact with a hydrated metal salt.  The solvent used may be an aromatic hydrocarbon, e.g. benzene, toluene, xylene or carbon tetrachloride and hydrated metal salts specified are ferric chloride, ferrouschloride, stannic chloride and copper sulphate; a condensing agent may also be added, e.g. anhydrous ferric chloride, aluminium chloride or antimony trichloride.  Intermediate condensates prepared as described in Specifications 585,626 and 585,627 are preferred.  An intermediate methyl silicone prepared as described in Specification 585,627 was dissolved in toluene and antimony pentachloride and hydrated ferric chloride added.  The solution was refluxed for two hours at about 100 DEG  C. and then washed with water and distilled to remove solvent.  The product was used to impregnate woven glass tape and the dried tape crazed only after heating for 30 days to 275 DEG  C.  Specifications 542,655 and 548,911 also are referred to.

Title: Improvements in and relating to pneumatic brakes of rail vehicles
IPC: B60T15/48
Filed: 1957-01-24
Abstract: 820,755. Fluid-pressure brakes. DANEK, J., and KOVOLIS NARODNI PODNIK. Jan. 24, 1957, No. 2632/57. Class 103 (1). In order to prevent too rapid replenishment of the auxiliary air reservoirs PV, which may take place with respect to such reservoirs at the beginning of the system, when the driver uses so-called " filling impulses" in releasing the brakes, so that a large amount of air is withdrawn, and the release of the brakes at the end of the system is slowed down, a valve device is used whereby the resistance to flow between the main air-line HP and the reservoir PV is varied in dependence on the pressure difference between the main air line HP and the reservoir PV. As shown in Fig. 1, the valve 25 has an edge Y, which when the valve is lifted against spring 26 by a large pressure difference across its ends closes the gap across to the edge X of the valve guide, thus reducing the flow into the auxiliary reservoir PV. In the embodiment shown in Fig. 2, the valve 25 has an inclined surface P for co-operation with the edge X of the valve guide.

A gas-fuelled cigarette lighter and windshield are so constructed that the latter cannot be rotated away from its normal shielding position but can be moved laterally of the burner to position in which it is freed for rotation. The windshield comprises a U-shaped member 82 joined by offset portions 90 and 91 to two legs 83 and 84 which have slots 92 and 93 through which passes the pivot pin 42 of the lighter spark wheel 54. The offset portions 90 and 91 of the windshield are sloping and in the normal shielding position abut the correspondingly sloping edges 87 and 88 of the spark wheel supporting ears 38 and 39, thus preventing rotation of the windshield. The windshield is held in this position by the engagement of two crimped ridges 94 and 95 on the shield legs with grooves 80 and 81 in the ears 38 and 39. The ridges and grooves are located in front of the pivot pin 42 as shown, but may be located rearwardly of the pin. By squeezing the legs of the windshield together the ridges 94 and 95 may be disengaged from the grooves 80 and 81 and the shield moved forwardly, as is permitted by the slots 92 and 93 to a position whence it may be rotated away from the burner 25. The lower edge of the windshield partially overlaps an operating ring 33 of the lighter burner 25 to permit access of air to the burner. The burner comprises a threaded body 26 which screws into an opening 23 in the lighter casing, an adjusting rotatable bushing 27 provided with vertical grooves 32 meshing with corresponding grooves 34 on the inner surface of the operating ring 33, and a burner valve operating rod 29 located in the burner outlet 28. A fuel charging valve assembly 20 is threaded into the bottom of the lighter casing. Specification 896,190 is referred to.
