Abstract: 933,543. Making box girders. J. ROSANES. July 15, 1960 [May 31, 1960], No. 24644/60. Classes 83 (2) and 83 (4). A method of forming a hollow, box-type tapering beam from sheet metal comprises the steps of providing an elongated blank of sheet metal of the required thickness, marking thereon the positions of the longitudinal edges of the tapering beam to be produced, cutting if necessary along the outer edge markings, bending along the remaining markings until the outer longitudinal edges of the blank abut or are closely adjacent each other and finally connecting the outer edges by welding to form one longitudinal edge of the beam. The blank shown at Fig. 2 would have the bends made in the following order, first along line DM, second along line BF, and finally along line AE. Due to the inherent springiness of the metal, the edges abut when the folded blank is drawn off the bending tool.

Title: Production of chemical compounds
Filed: 1945-09-24
Abstract: Resinous products are made by reacting a vinyl ester of a carboxylic acid with perchloroethylene under conditions favourable to polymerization of the ester.  Esters specified are vinyl formate, acetate, propionate, butyrate, oleate and stearate. The reaction may be carried out in solution or emulsion.  Suitable catalysts are those described in Specification 581,899.  The constituents of the mixture may be separated by distillation under reduced pressure.  The products have the general formula <FORM:0599762/IV/1> where R is an acyl group and n is 1 to 8.  They may be hydrolysed to polyhydroxy compounds.  In an example, an aqueous emulsion of vinyl acetate and perchloroethylene containing dextrin is heated at 30-60 DEG  C. in the presence of hydrogen peroxide activated by zinc formaldehyde sulphoxylate.  The dispersion is steam distilled and coagulated with aluminium sulphate to yield a tacky resin.

Abstract: 1,112,444. Arc blow torches. BRITISH TITAN PRODUCTS CO. Ltd. 19 Aug., 1966 [15 June, 1965], No. 25193/65. Heading H5H. A process for initiating the arc of a plasma gun comprises continuously passing a primary gas between the electrodes which have a P.D. less than the breakdown potential of the primary gas, introducing :momentarily a secondary gas or gas mixture which produces a gaseous mixture having a breakdown potential less than the electrode P.D., discontinuing the secondary gas(es) when the arc is initiated and thereafter maintaining the arc in the primary gas. The primary gas may be oxygen and the secondary helium; or the primary may be hydrogen, nitrogen, chlorine, carbon dioxide, carbon monoxide, ammonia, hydrogen chloride, nitrogen oxides, sulphur dioxide, methane, or argon (when not used as a secondary gas), and the secondary may be one or more of helium, neon or argon. Alternatively the primary gas may be helium or neon and one of the previous primary gases may be used as a secondary gas. The concentration of secondary gas is preferably greater than 90% and it is preferably introduced at 5 to 500 p.s.i. above the pressure between the electrodes. Preferably the secondary gas is introduced via a conduit in contact with one of the electrodes and is directed at the surface of the other electrode. Three diagrammatic embodiments of plasma gun are desoribed.

Abstract: 843,791. Control of A.C. motors; controllers. CLARKE, CHAPMAN & CO. Ltd., and BROWN, A. S. July 28, 1958 [Aug. 9, 1957], No. 25227/57. Class 38 (3). An induction motor driving a winch or capstan has stator windings 1 and is controlled by a master switch M. When this switch is in its second hoisting or lowering positions, the coil 13 of a relay D is energized so that the stator windings are connected in delta for normal operation. An overload in the stator circuit causes torque-limit relay 3 to open contacts 26 to disconnect a time-delay relay 25, whereby contact 21 moves from its lower to its upper position after a period to de-energize coils 13, 15 of the delta contactor and a transfer relay 15 respectively. The contactor D drops out to disconnect the stator windings 1, and closes contact 22. The transfer relay drops out after a short delay period and closes contact 23 so that coil 24 of a star contactor S is energized and the motor is stalled without overheating, the stall-current of the starconnection being less than the setting of an overload relay 34. The coil 6 of a magnetic brake is always energized whilst the winch is in operation since hoist contact 9 is closed if lower contact 8 is open, and delta contact 11 is closed if star contact 10 is open. In another embodiment, the load-limiting circuit comprises a transformer which may be switched in by the relay to provide a reduced voltage across the stator winding. The motor may have high and low-speed windings, the torque-limit relay switching-in the low-speed winding when an overload occurs. A further torque-limit relay may change the stator windings from delta to star if the overload persists.

Abstract: 727,127. Bogies for railway vehicles; rubber springs. GENERAL MOTORS CORPORATION. Sept. 15, 1953 [Dec. 29, 1952], No. 25415/53. Classes 103 (6) and 108 (3). A railway bogie comprises a frame with longitudinally and laterally spaced pockets containing springs, a bolster supported by the springs and resilient means on the frame to engage the bolster to transmit longitudinal movement from the frame to the bolster. As shown, a locomotive bogie comprises a frame 2 with side frames 4 and transverse transoms 6. Each side frame has three pairs of pedestal jaws 8 with retainer bars and pedestal liners which guide journal boxes 12 for axles 14 carrying wheels 16. The journal boxes of the centre axle and the outer axles are connected by four sets of equalizer bars 18 which support the frame 2 resiliently. Each transom 6 has pockets 28 for helical springs 32 which support resiliently the ends of transverse arms 36 of a bolster 38. Bolts 44 secured to the bolster arms and passing through slots in the transoms 6 and in stops 55 thereon prevent the bolster from being removed completely from the frame 2 while allowing limited relative vertical and lateral movement. To transmit longitudinal movement from the frame 2 to the bolster, each transom 6 has upstanding end-facing wear plates 61, 62 opposite wear plates 60 on the ends of the bolster arms 36. Two diagonallyopposite wear plates 61 on the transoms are apertured to receive spring-loaded friction plates 63 which engage the wear plates 60 to damp lateral and vertical movements of the bolster. Each friction plate is mounted on a plunger 64 slidable in a bore 65 in an upstanding projection 67 on the transom, and engaged by a spring 66. To limit lateral movement of the bolster 38 a resilient lateral stop 70 is provided at the centre of the upper side of each transom 6, the stop comprising a housing 71 provided with ribs to accommodate a shock absorber. The shock absorber includes an outer housing 82 and an inner housing 84 which are held apart axially by three resilient thrust units each consisting of a rubber section 86 of frusto-conical shape surrounding an inner shell 88 and surrounded by an outer shell 90. The resilient thrust units are separated axially by two cones 92. The housings 82, 84 have wear plates 94, 96 respectively, opposite which are disposed wear plates 98 on a bolster arm. Upon lateral movement of the bolster relatively to the frame 2 the wear plates 98 on one side enter openings in the ends of the housing 71 and engage the wear plates 94 or 96, against action of the resilient thrust units.
