Abstract: 913,893. Laminates. YOSHIKAWA, M. Sept. 4, 1959 [Sept. 6, 1958], No. 30326/59. Class 140. [Also in Group X] Sheet building material used for walls and roofing comprises a rigid corrugated layer 1 and a layer 2, of organic material secured to the crests of the corrugations of layer 1 and having sufficient elasticity to conform to the shape of that layer during piling for storage. Layer 1 may comprise cement-fibre, plywood, reinforced wood, synthetic resin, consolidated animal, vegetable or mineral fibres, metal, or hardboard. Layer 2 may comprise naturally elastic material, such as natural or synthetic rubber or elastomeric synthetic resin, organic material having corrugations small in comparison with those of layer 1, foamed material such as polyurethane or polyvinyl chloride-sponge, or synthetic resin mouldable to the shape of layer 1 by heating, either before or after being applied thereto, and capable of recovery to flat shape by reheating. Examples of such materials are polythene, polyvinyl chloride, vinyl chloride-vinylidene chloride copolymer and nylon. A layer such as 2, for example a sponge layer and a synthetic resin layer, respectively, may be applied to each side of sheet 1. The layer or layers 2 may be secured by adhesive or heat welding, and one or both ends thereof may be closed by adhesion to the whole adjacent surface of sheet 1. The sheets are heat- and sound-insulating.
Patent GB-1014083-A (GB)
Title: Method of producing a gel
Inventor: OXLEY CHARLES EDWARD
IPC: B01J13/00
Filed: 1962-08-08
Abstract: A titanium oxide gel is produced by hydrolysing a mixture of an organic titanium ester Ti(OR)4, where R is an alkyl group having 2-6 carbon atoms, and an aminoalcohol N(R1)(R2)(R3).  The groups R1, R2 and R3 together contain at least 3 carbon atoms, and may be straight chain hydroxyalkyl having 2-5 carbon atoms, or branched chain polyhydroxyalkyl having 4-5 carbon atoms; R1 and R2 may also be hydrogen or alkyl having 1-5 carbon atoms. At least 1/n moles of aminoalcohol are used per mole of Ti ester, where n is the number of R1, R2 and R3 groups which are hydroxyalkyl.  Preferred reagents are n-butyl orthotitanate and N-methyl ethanolamine, di- or tri-ethanolamine, or 2-amino-2-ethyl propan-1,3-diol.  Hydrolysis may be effected by adding water to the mixture, alone or diluted with, e.g. methanol, ethanol, n- and iso-propanol; these solvents may also be included in the mixture.  Refractory articles are produced by adding refractory powder, e.g. zircon, alumina, or sillimanite, prior to gelling; then shaping, allowing to gel and harden, and firing.

Title: Oilburner of the return flow type
IPC: F23D11/28
Filed: 1958-09-24
Abstract: 897,737. Supplying liquid fuel to burners. LIAGO S. A. Sept. 24, 1958 [July 9, 1958],No. 30543/58. Class 75(1) In an oil supply system for a return flow type burner 16 comprising a by-pass valve 2 controlling a short-circuit path 5 between the oil supply conduit 7 and the return conduit 6, the oil supply conduit 7 is connected with a manometer 20 operating a switch 21 which opens to stop the motor driving the fuel pump 8 when the oil supply pressure exceeds a predetermined value. At starting the by-pass valve 2 is open and the pump motor is energized by a relay unit 10 which also energizes through connections 13, 14 a blower motor and a filament igniter. The oil therefore circulates in the system and is unable to build up a pressure sufficient to open a regulating valve (not shown) controlling the conduit 15 leading to the burner 16. After a predetermined period the solenoid 4, holding- the by-pass valve 2 open, is de-energized by the relay unit 10 and the valve suddenly closes. The sudden pressure build-up opens the regulating valve to the burner but does not open the manometer switch 21 (although less pressure is required therefor) since the pressure is damped in the conduit to the manometer and since the pressure is immediately reduced by the discharge from the burner. If at starting the by-pass valve 2 is stuck in closed condition a gradual build-up of pressure occurs which results in the opening of the manometer switch 21 to switch off the pump before the pressure is sufficient to open the regulating valve leading to the burner.

Title: Improvements in or relating to bituminous emulsions
IPC: C08L95/00
Filed: 1925-12-03
Abstract: 268,411. Levy, F. Dec. 3, 1925. Emulsions, making.-An aqueous bituminous emulsion is produced by mixing together molten bituminous material and a hot aqueous solution of an alkali silicate, emulsification being effected without the addition of any fatty or other saponifiable matter. In one example, Mexican asphalt, melted at a temperature of 215-225‹ F., is added slowly to a hot two per cent solution of sodium silicate powder in water, agitation of the mixture being continued until emulsification has been effected. In another example, a solution containing 1.4 grams of sodium silicate in 196 c.cs. of water is heated to 185‹ F. and Mexican asphalt at approximately the same temperature is run in slowly, agitation being continued until the emulsification has been effected. The process may be carried out continuously. Specification 3914/08, [Class 91, Oils &c.], is referred to.

Divided out of 456,897 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 28, 1935. [Class 108 (iii)] A shock strut, particu. larly for aeroplanes, comprises an upper member consisting of concentric cylinders 10, 34 the outer cylinder 10 being provided at its upper and lower ends with attachment means such as a bifurcated device 12 and lugs 28 respectively while a lower slidable cylinder 56 is guided between the cylinders 10, 34 by an apertured piston 36 on the cylinder 34 and by a closure device on the inner end of the cylinder 10 such as packing 18 contained between a nut 24 and a movable ring 22. On maximum extension of the strut the ring 22 is engaged by a collar 58 on the cylinder 56 and the packing is compressed. A metering pin 62 carried by the cylinder 56 co-operates with the aperture 44 in the piston 36 above which is mounted a snubbing chamber 46 having a non-return flap-valve 52 at its upper end and small openings 54 at its lower end. On compression of the device liquid is forced through che gradually-decreasing aperture 44, up through chamber 46 and past valve 52, and through holes 3S in cylinder 10 into the annular space between the cylinders 10, 34, compressing air or gas in the upper ends of the cylinders. On rebound, the valve 52 closes and liquid is forced by the compressed fluid through the openings 54 and 44 back into cylinder 56. Brace members may be secured to the lugs 28. In a modification the packing is movable with the cylinder 56 and again acts as a cushion at the end of the rebound movement when the end of a long, bending-resisting sleeve arranged inside the cylinder 10 engages a I, slidable, packing-retaining ring. In another modification the chamber 46 is omitted and I the flap-valve 52 mounted on a diaphragm fixed in the cylinder 10.
