Title: Sliver failure detection device
Inventor: SCOTT GEORGE ERSKINE
IPC: D01H13/16
Filed: 1954-08-23
Abstract: 773,219. Stop mechanism. FRASER & SONS, Ltd., D. Nov. 23, 1955 [Aug. 23, 1954], No. 24423/54. Class 120 (2). A sliver failure detection device for effecting automatic stoppage of a drawing frame or other textile machine on cessation of the feed of sliver from a sliver roll 2 wound on an arbor or centre member 1 and resting on a cradle constituted by a pair of parallel rollers 4 and 5, incorporates an electrical conductor 3 so mounted on the periphery of the arbor 1 that when the arbor contacts the roll-supporting rollers an electrical circuit is completed. In the embodiment shown, rollers 4 and 5 are connected in an electric circuit by means of brushes and the conductor 3 completes the circuit on exhaustion of the sliver on the arbor 1.

Title: Welding gun
IPC: B23K9/26
Filed: 1974-06-03
Abstract: 1463741 Welding by fusion CATERPILLAR TRACTOR CO 3 June 1974 [1 June 1973] 24532/74 Heading B3R A gas-less or, as shown, gas-shielded consumable electrode arc welding gun, provided with fume extraction means, comprises an electrically conducting electrode contact tube 31, and an interchangeable, electrically insulating, high melting point material, "electrode-stick out" guide tube 10, e.g. of ceramics such as zirconium oxide, alumina, silicon nitride, which guide tube engages over said contact tube and is supported by and within a surrounding detachable tubular member 22 (e.g. of copper). The "stick-out" of the electrode provides for resistance heating of the electrode prior to the arc heating. The guide tube 10 and member 22 have respective co-operating tapered and cylindrical surfaces 17, 23 and 18, 24 the guide tube being retained on the gun by the member 22 which is threaded, at 37, on to a gun conduit 33. Preferably, the latter has an insulating liner 42. The guide tube shown has slots 19 co-operating with the member 22 to provide gas flow passages 25 for gas-shielded welding use (the member 22 functioning as a gas nozzle), and may be interchanged with an alternative guide tube (Figs. 2, 4, not shown) in which, for gas-less welding use, the slots 19 are dispensed with. The guide tube is counterbored at 56 to accept the forward end of the contact tube, electrode "stick-out" being changeable by modification of counterbore depth and contact tube length. The contact tube is retained in a counterbore 46 of an inner conduit 34 by a nut 36. The conduits 33, 34 cooperate to form a shielding gas passage 38. Conical counterbores 53, 54, 57 respectively in the conduit 34 and contact and guide tubes facilitate electrode insertion. An outer conduit 32, threaded on to a gun housing (39) and having inner protrusions 38 to support the conduit 33, co-operates with the latter to provide a fume extraction passage 47, the member 22 comprising a fume direction lip 27. Welding current supply, shielding gas flow, and application of vacuum to the passage 47 are preferably simultaneously controlled by actuation of a gun trigger. The Specification refers to use of a mixture of CO 2  and A with "gas-flux" cored electrode wire or of a single gas (e.g. CO 2  or A) in gasshielded arc welding, or of a "gas-less flux" cored electrode wire in gas-less arc welding. The ceramic material of the guide tube reduces weld spatter accumulation.

Abstract: 1345257 Thrust nozzles MESSERSCHMITTBOLKOW-BLOHM GmbH 19 April 1971 [8 May 1970] 24909/71 Heading F1J [Also in Division F2] Thrust nozzle for a rocket propulsion unit has a divergent body portion 12 in which rows of apertures 17a-g are formed. The total crosssectional area of the bores in any one row is small compared with the local cross-sectional area of the nozzle. The frictional loss as propulsion gas flows through the nozzle is reduced by the withdrawal of a small quantity of the gas through the apertures thereby maintaining laminar flow along the walls of the nozzle and enabling the use of a ratio of end surface to neck surface of e.g. 400. In an alternative construction, the nozzle is made up of alternate bands of impermeable and permeable material.

[Also in Division El] A permanent shutter for e.g. concrete walls comprises spaced facing sheets of a synthetic resin bonded material with an intermediate two- or three-dimensional concrete-reinforcing grid bonded by the resin to the facing sheets. The grid may be of a wire mesh or steel bars, initially sand blasted, then chemically cleaned, then coated with molten zinc or aluminium spray. Each facing sheet is moulded by spraying, e.g. a polyester gel coat on the mould and incorporating sodium bicarbonate therein, then, optionally, spraying on a mixture of aggregate and polyester in a ratio between 9: 1 and 4: 1, or a layer of resin and powdered fillers, then adding a layer of glass fibres and resin, and finally spraying on sand or grit with, optionally, additional resin. The layers are then consolidated using a flexible hood and evacuating the air between the hood and the sheet and also, optionally, applying pressure to the hood. The reinforcing grid is partially sprayed with glass fibres and resin, and then pressed into the sheet, using the hood. The first sheet, with the grid attached to it, is then connected in the same way to the second sheet. The initial gel coat may be sprayed with glass fibres to bond it to the next layer, and epoxy or phenolic resins may be used instead of the polyester resin. The edges of the facing sheets may be connected by sheets of resin-bonded material formed in the mould with the facing sheets. Withdrawable plugs are fitted into the shutters at points where air may be trapped when filling the shutters with concrete on site, where the shutters are supported by feltcovered beams and shores.

Title: A method of and an arrangement for the conversion of heat from a nuclear fission reaction into electric energy

Abstract: 1,006,613. Nuclear power plant. LICENTIA PATENT VERWALTUNGS-G.m.b.H. July 3, 1962 [July 3, 1961; July 5, 1961], No. 25479/62. Heading G6C. [Also in Division H2] An arrangement for converting the heat from a nuclear fission reaction into electrical energy by means of an electric conductor used as a working medium, comprises several reaction zones connected together by non-reactive zones, the heat evolved in the reaction zones causing evaporation of part of the working medium to cause movement of the non-evaporated part through the non-reactive zones where electricity is generated by movement of the conductor through a magnetic field. In the arrangement shown in plan in Fig. 2 a cylindrical tube is partly filled with a solution of fissile material, and the ends of the tube are of larger dimensions (this is not shown in the plan view) so that when either end is filled with the solution it becomes critical and fission reaction occurs. The heat evolved from the fission process vaporizes some of the solution and drives liquid to the other end. The cycle repeats and liquid is reciprocated from one end of the tube to the other, and while it moves through the centre part of the tube, which is immersed in a magnetic field, an electromotive force is generated between electrodes E. To maintain the cycle the working medium must be cooled in the centre of the tube, and this is done by cooling electrodes E with a cooling medium K. Control rods may be provided in the section zones at each end of the tube. In another arrangement, Fig. 8, the reaction chamber 8 communicates through a nozzle Dœ with a toroidal tube so that the pressure in the chamber causes liquid to flow round the toridal tube which is placed in a magnetic field. The electrodes and the magnetic field may be divided into three regions, the field being energized by three phase A.C. to produce a three-phase A.C. output. Two toroidal tubes may be arranged with two reaction chamber units, the exhaust of each tube feeding into a reaction chamber which provides the input to the other tube, Fig. 9 (not shown). In a modification, Fig. 10 (not shown) two reaction chambers are arranged in series with two tubes in the form of loops so that the exhaust of each loop provides the input to a reaction chamber. The working medium may be mixed homogenously with the fissile material, or the fissile material may be mounted in the reaction zones in the form of thin sheets or wires.
