Title: Method and device for transporting elongated flexible elements
IPC: D01D10/04
Filed: 1966-11-04
Abstract: 1,138,884. Transporting device for flexible elements. ZINSER-TEXTILMASCHINEN G.m.b.H. 4 Nov., 1966 [5 Nov., 1965], No. 49622/66. Heading B5B. [Also in Divisions B3 and D1] In an apparatus for transporting an elongated flexible element 14 through a treatment area such as when the element is heat stretched, said element is oscillated on a heating block 17, the oscillation being transverse to the direction of movement of the element, said oscillation avoiding the formation of a groove in the heating block and consequent damage to the flexible element. The element is delivered to a first contact point 11 on a transporting roller 12, and is laid in several loops about said transporting roller and a control roller 13, which has its axis inclined at a small angle to that of the transporting roller, and extends from the final point of contact 16 on said transporting roller to a first point of contact 20 on a second transporting roller 19, the two transporting rollers being driven at different speeds, thus causing stretching of the element to occur. An operating means 37a having a shifting bar 32, is connected to a mounting means (not shown) for the control roller, by a lever arm 31, which also engages the control roller. On reciprocating said bar the mounting means is angularly displaced together with the control roller so that the axis of the control roller moves along an imaginary cone surface sector, corresponding to a movement of the said axis in two mutually perpendicular directions. Movement of the control roller by the operating means in this manner causes loops 15 to slide backwards and forwards along the rollers, thus causing the flexible element to oscillate across the heating block. Axial displacement of the last loop and last point of contact on the second transporting roller 19 may be prevented by connecting the first mounting means with a similar mounting means (not shown) for the second control roller 22, by either a connecting rod or chain, so that the second control roller is angularly displaced in the manner described but with said second control roller inclined in the opposite direction to the first control roller. Flexible elements mentioned include, threads, rope, synthetic filament, yarn, or wire.

Abstract: 1413333 Hydrogen fluoride and SiO 2  from waste gases G L FLEMMERT 27 Oct 1972 [28 Oct 1971] 49703/72 Heading C1A Pure HF and SiO 2  are produced from waste gas containing SiF 4  and HF and optionally SiO 2 , by absorbing the gas in water when hydrofluorosilicic acid is formed, which is then mixed with conc. sulphuric acid so as to be decomposed and form a gaseous effluent comprising SiF 4  + HF ; the residual sulphuric acid is withdrawn from the decomposition stage, and the gaseous effluent is treated with cone. sulphuric acid to absorb water and HF, the SiF 4  being recovered and hydrolysed by blending it with combustible gas and air and burning to form SiO 2  and HF, the temperature of the reaction being maintained above the dew point to prevent the water condensing on the silica, separating the silica, and treating the effluent gases with water or aqueous HE to form hydrofluorosilicic acid, venting the remaining gas, and then decomposing the hydrofluoro-silicic acid with sulphuric acid, so liberating gases containing SiF 4 , HF and water vapour, removing the water vapour and HF, recycling the SiF 4  to the hydrolysis stage, separating the HF and recovering the sulphuric acid. The hydrofluorosilicic acid produced from the initial waste gas and that produced after the SiF 4  hydrolysis stage may be combined and decomposed together. When SiO 2  is also present in the waste gases, then conditions may be such that the reaction with conc. sulphuric acid produces only water and SiF 4 . The proportion of HF to SiF 4  formed in the decomposition may be controlled by adjusting the molar proportions of SiF 4  and H 2 SiF 6  in the reaction mixture. Steam may be added to the combustion zone to improve the hydrolysis of the SiF 4 . Particular concentrations and conditions of the various reaction stages are given in the Specification.

A perforated evacuation pipe 2 is surrounded with a wire-netting filter 4. The box 1 is vibrated, for packing, before the film 13 is fitted. The openings 8 and 9 in the pattern 6 may be filled with the material 12 or by separate cores. In a modification, the pattern 27, Fig. 3, is covered with a layer 30 formed either by a synthetic resin film, preformed or applied initially in liquid form, or by plaster or clay. A gas vent 34 may be provided. In a further modification, a resin film 56, Fig. 5, 20 to 50 microns thick, is heated or treated with a solvent and sucked into contact with a wooden pattern 49 by suction through passages 53, 54 and an opening 55. A runnerforming member 57 of combustible synthetic resinous material is mounted on a pattern rib 52 and a similar polystyrene or polyethylene gas-vent-forming member 58 communicating with a further vent is also provided. A box half 41 is then placed on the pattern, and sand &c. 59 poured in. The box is vibrated, covered with a film 60 and evacuated, e.g. through openings 42 in the walls and a surrounding passage 44. The evacuation means is then disconnected and air under pressure is supplied to the pattern passages 53, 54 causing the film 56 to separate from the pattern (which is removed) and remain with the box half 41. The above procedure is repeated with a second box half 41 and the halves brought together, Fig. 6, with an interposed core 61 in the mould cavity 62. The metal is poured on the member 57 to burn it.

Abstract: 504,670. Cables; synthetic rubber. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and HAMILTON, G. M. Feb. 10, 1938, No. 4222. Drawings to Specification. [Class 36] [Also in Group V] In an impregnated cable of the kind having within the cable means for compensating for expansion and contraction of the impregnating compound, the compensating means consists of one or more bodies formed of material consisting of mixed polymers of butadiene and acrylonitrile, sold under the Registered Trade Mark " Buna as "Buna N," and containing a large number of small closed gas cells separated from each other by thin walls. The compensating means may be located within a hollow conductor of the cable, or between the dielectric and the sheath. The initial gas pressure within the cells may be different in different parts of the cable, particularly when the cable is laid on a gradient. The cellular form may be imparted to the " Buna N " either before or after its insertion in the cable. In the former case the material may be shaped by extrusion and then subjected to gassing for six to twenty-four hours with nitrogen or a mixture of nitrogen and carbon-dioxide at a pressure of 1800 pounds per square inch. On release of the pressure, the dissolved gas is liberated and produces a cellular material. This is then vulcanized. When the cellular structure is to be imparted to the material after its insertion in the cable, the material is mixed with substances which evolve gas by the action of heat involved in drying and impregnating the cable.

Abstract: 1,172,098. Producing metals and alloys. H. WESSEL. Nov. 17, 1966, No.51556/66. Heading C7D. [Also in Division C1] In a continuous process for the production of metals, alloys, or metal compounds (see Division C1), a starting material including a metal or metallic compound is suspended in an inflammable liquid, the suspension is injected into a flame spray device to burn the inflammable liquid and form either a metal-containing product when the suspension contains metal, or a metal or metal-containing product when the suspension contains a metallic compound, and the stream of flame and metal or metal-containing product is passed down a sleeve provided with a sequence of throats for creating within the sleeve zones of high and low pressure. As shown, suitable apparatus comprises a water-cooled sleeve separated into five zones I-V by throats 12, 14, 20, 21: the sixth zone VI is a collecting chamber 26. Suspension 3 is injected as a spray by an injection agent 2 (which may be steam to produce a reducing atmosphere, i. e. water-gas, by reaction with the burning inflammable liquid) into flame 7. The products of combustion begin to separate into product particles 25 and gases in zone IV. Thus metal drops 25 are collected in chamber 26 while any slag 24 is blown out by air injected at 23 to be collected in well 27. For the production of alloys chamber 26 is omitted: zone V is then provided with a cyclone. The atmosphere in the sleeve may be made neutral or oxidizing, e. g. by admitting at the throats superheated steam, hydrocarbon, oxygen or air: fuel may also be admitted. Metal product in chamber 26 may be refined by injection of air, oxygenenriched air or argon through perforated plate 28. For the production of sintered bodies, chamber 26 may take the form of open boxes on a conveyer, each with a perforated floor. In the Examples (1) lead is produced by using a starting material lead oxide plus a glass composition suspended in benzene-lanoline, and (2) lead-titanium is produced as in (1), but by replacing the benzene-lanoline by butyl titanate as the inflammable liquid.
