Title: Recirculating gas blast circuit interrupter
IPC: H01H33/835
Filed: 1957-11-19
Abstract: 833,559. Gas-blast switches. I-T-E CIRCUIT BREAKER CO. Nov. 19, 1957 [June 21, 1957], No. 36032/57. Class 38 (5) [Also in Group XXXVI] A double-break recirculating gas-blast switch has axially aligned fixed and movable contacts 17, 38 housed within a tank 11 which is connected to a high pressure gas source so that the contacts are surrounded by high pressure gas. The movable contacts 38 are carried by pistons 37 which are slidable in a cylinder 30. Normally, the pressure within the cylinder is the same as that within the tank and the contacts are maintained closed by springs 45. To open the switch, a pipe 34 is connected to a low-pressure reservoir so that the pressure within the cylinder is reduced and the pressure in the tank acting on the pistons causes them to move towards each other to open the contacts. A gas-blast flows from the tank through each movable contact 38, openings 55 in plates 46 and the pipe 34 to the low-pressure reservoir until the pistons 37 rest on seats 56 which close the outlets from the contacts 38. To reclose the switch the pipe 34 is disconnected from the low pressure reservoir and connected to the high pressure source so that the pressures on both sides of each piston are equalized and the springs 45 are able to reclose the contacts. Fig. 4 (not shown) illustrates the external gas pipe and valve gear arrangement for a threepole or six-break assembly.

Abstract: 1304540 Moulding reinforced resin articles; laminated products SOC RHODIACETA 24 July 1970 [25 July 1969] 36091/70 Addition to 1170977 Headings B5A and B5N [Also in Division D1] Rigid deep drawn fibre-reinforced resin articles are made by moulding to shape under pressure at least one needled textile sheet formed from oriented continuous randomly disposed synthetic filaments, the sheet being impregnated with a resin and the sheet or the filaments of the sheet being coated with cross-linked organopolysiloxane, the total weight of which is 0À01% to 5% of the weight of the textile sheet without the impregnating resin. The textile sheets may be laminated to themselves or may be laminated to glass fabric sheets. The filaments are preferably of polyethylene terephthalate, the impregnating resin is preferably a polyester, although any of those mentioned in Specification 1170977 can be used, and the organopolysiloxane is preferably a dispersion of vinyltris (methoxyethoxy) silane. In one example, three sheets having constituents as described above are laminated and pressed to shape and in other examples such sheets are combined with glass fibre sheets, a glass fibre sheet preferably being interposed two needled sheets.  In one example, the needled sheet is made by melt spinning drawn continuous filaments of polyethylene terephthalate, directing the filaments by means of an oscillating deflector on to an endless belt to form a non-woven sheet, calendering the sheet by means of hot cylinders spaced 1À5 mm. apart and needle punching the sheet by a loom having needles with nine barbs adjusted to give 75 strokes/cm<SP>2</SP> and a thickness of 3 mm. The sheet, which weighs 300 grms/m<SP>2</SP> is then sprayed with an aqueous dispersion of vinyltris (methoxyethoxy) silane to a weight of 0À5 wt. percent, dried, and finally impregnated by passage through a trough containing a solution of a resin based on a polypropylene glycol phthalate and polypropylene glycol maleate in styrene, the solution containing 1% methylethyl ketone peroxide as catalyst and 0À1% of cobalt octoate accelerator. Thereafter the sheet is drained and dried.

Abstract: 488,356. Harvesting-machines. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd. (International Harvester Co.) Dec. 31, 1937, No. 36236. [Class 6 (iii)] To facilitate the transport of a combined harvester thrasher of the type in which a screw conveyer 27 moves the cut crop along the platform into the longitudinally arranged feeder 18 of the thrasher, the screw conveyer is supported from the grain end of the platform and the platform is hinged so that its outer end, with the conveyer, can be swung upwards to reduce the width of the machine. The longitudinally arranged thrasher 5 extends rearwardly of the main axle 1 from which a draught frame 4 extends forwardly on the stubble side of the machine. The forward lower edge of the thrasher frame carries a transverse shaft on which a bar is pivoted extending forward as an angle frame 14 and rearwardly and upwardly curved angle bars 15 carrying a curved metal trough 16 with backboard 17 forming the platform of the harvester ; the outer end of this harvester unit is similarly carried on a pivot 19 supported from the axle 1 coaxially with the transverse shaft. The outer end of the platform frame carries a braced vertical plate with a cylindrical mounting for the shaft supporting the sleeve shaft of the screw conveyer 27; the plate is adjustable so that the conveyer may be maintained in correct position relatively to the trough. The stubble end of the conveyer terminates in a cone which is situated just above a ramp 29 leading from the level of the bottom of the trough 16 to the level of the feeder 18. The platform 16 is divided just within the plane of the grain wheel on the main axle, the two parts being held together by bolts passing through two contacting angle frames 15, the knife bar being divided correspondingly and hinges being fitted at the upper end of the back board 17 and on the knife bar to permit, after detachment of the bolts and removal of the reel, the outer part of the harvester being swung upwardly and forwardly to a vertical position where it is locked for transport. The conveyer is driven from a shaft 47 fitted at its end with a self-centring spring clutch adapted to engage the co-operating end of driving shaft 52 on the thrasher. The thrasher is provided with an attendant's platform 9, 11, of which the front rail is formed by a shaft 83 fitted with a pin wheel engaging a rack on a rod 81 connected to a crank extending from an eccentric rocker bracket 73, this bracket being connected by a chain and rod 79 to the harvester frame and by a chain 74 to counterbalancing springs 75. A wheel 85 is provided to turn the shaft 83 to adjust the position of the harvester and so the height of cut. The reel 43, when detached for transport, is carried on brackets on the thrasher 5.

Abstract: 1367451 Nuclear reactors BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd 27 Sept 1971 [29 July 1970] 36805/70 Heading G6C In a sodium-cooled nuclear reactor, the core and heat exchangers are mounted together within a prestressed concrete pressure vessel and the core is offset from the vessel centre to effect an efficient use of the internal space. The asymmetrical, thermally generated stresses in the coolant system pipework are resisted by the core support structure. The core 16 and the heat exchangers, 20, are connected by the ducts 26, 28 and mounted in the concrete pressure vessel, 10. The core and heat exchangers are anchored to the beams, 50, which, with the base part 18<SP>1</SP> of the shield 18, constitutes a supporting base structure. The top cover, 19, is designed to fail progressively during high, transient pressures in the core. The mixers, 30, ensure that coolant leaving a faulty secondary coolant circuit, 34, is cooled by sodium from the remaining exchangers. The liner, 12, has a heat resistant covering, 40, and a thermally conductive covering, 42. The tubes 44 carry cooling air. Thermal stresses in the liner 12 at the level of the cold pool 24 are reduced by minimizing variations in this level; to this end, the cold pool has a surface area large compared with that of the hot pool 36. In another embodiment (Figs. 5 and 6, not shown), the level of the cold pool is controlled and maintained constant by employing variable differential pressure in an inert gas above the hot and cold pools (which are separated by extending the hot pool dam (36) to the roof of the pressure vessel). The pressure in volume (38) is adjusted by pump means controlled by sensing means.
