Title: Adjustable former
IPC: B29C53/78
Filed: 1973-08-09
Abstract: 1445427 Adjustable former CREATORS Ltd 30 July 1974 [9 Aug 1973] 37903/73 Heading F2P An adjustable former around which a strip may be helically wound to form a tube, comprises a primary inner forming roller 10, a series of auxiliary inner forming rollers 11-13, a series of inner guide rollers 19, a primary outer forming roller 16 and a series of outer guide rollers 18 said rollers 10, 11-13, 16, 18 and 19 being supported by a plate 14. Each inner roller (11-13) and its opposing outer guide roller 18 are mounted on a base member 27 which is releasably secured to the plate 14 by a locking stud which can be secured at any desired position along a guideway 25, roller 18 being adjustably secured to the base member 27 by an arm 30. The primary outer forming roller 16 forms a sealing nip with roller 10 which is rigidly fixed to the plate 14, the gap of said nip being variable by altering the position of roller 16 relative to roller 10. The inner guide rollers 19 are mounted on base members which are releasably secured in selected locations along their respective guideways 26. The rollers 10-13, 16 and 18 are driven at the same peripheral speed. To form a reinforced tube 9, thermoplastics tape (e.g. P.V.C. tape) 21 and reinforcement 22 in the form of P.V.C. covered wire are fed to the nip between rollers 10 and 16 via rollers 34 and 35 respectively. A hot air sealer 20 heats the strip 21 and reinforcement 22 before they enter the nip. The strip 21 and reinforcement 22 are helically wound, following a path 15 defined by the inner rollers 10-13 and in such a way that the longitudinal edges of each turn of the strip overlap each other and the reinforcement, said edges and reinforcement being heat sealed together in the nip provided by rollers 10 and 16. The rollers 10-13, 16 and 18 are helically grooved and when driven, tend to impart axial movement to the formed tube 9, which the removal of is assisted by a haul-off device (not shown). By altering the positions of the adjustably mounted rollers 11-13, 18, 19 on plate 14 the shape and thickness of path 15 and hence the shape and wall thickness of the tube 9 produced on the former, can be varied. The former may be used to produce a tube comprising an outer winding (40) (Fig. 3, not shown) of thermoplastics material and an inner winding of a reinforcing member (41) covered with thermoplastics material (42) the edge portions of adjacent overlapping turns of the outer member being heat sealed together and to the inner winding in such a way that the sealed overlap is restricted to a sector bounded by an arc (43) subtending an angle of not more than 100 degrees, the boundary radii of which intersect at the adjacent centre of the reinforcing member (41).

Rotary boring apparatus comprises a frame 36 carrying drive gearing 34, 38, clamping means 40 carried by the gear 34 and adapted to engage and rotate a casing 31, a boring tool 42 having gripping means 45 adapted to engage the casing to permit rotation of the tool by the casing and drive gearing, and power operated ground engaging members 39 adapted to feed the casing and tool into the earth. The gearing is driven by hydraulic motors having circuits arranged to reduce the speed of boring as the torque on the tool increases and vice versa. The circuits may be connected to the pump and hydraulic motor actuating the members 39 so that the rate of feed decreases with increase of torque on the tool. The gripping means grip as soon as the tool which has been lowered through the casing engages the earth, the grip being tightened by rotation of the casing which may carry cutters.

Title: Electrolytic metal producing process and apparatus
IPC: C25C3/18
Filed: 1972-08-22
Abstract: 1403892 Producing metals in fused electrolyte cells ALUMINUM CO OF AMERICA 22 Aug 1972 [8 Sept 1971(2) 9 Sept 1971(3)] 39033/72 Heading C7B Metal is produced from the metal chloride, e.g. Al from AlCl 3  or Mg from MgCl 2 , in a fused electrolyte cell including anode 14, at least one intermediate bi-polar electrode 15 and cathode 16 in superimposed spaced relationship defining inter-electrode spaces 19, by electrolyzing a bath comprising the metal chloride dissolved in molten solvent of higher decomposition potential than the metal chloride, such as alkali and/or alkaline earth metal halide, producing chlorine on each anode surface (41) and metal on each cathode surface (40), and establishing and maintaining a bath flow through each inter-electrode space to sweep out the metal produced and prevent its accumulation on the cathode surfaces, e.g. by using the chlorine produced as lifting gas to pump bath from the inter-electrode space upwardly while allowing molten metal swept therefrom to settle to a sump 4 below the cathode. The molten metal may be removed through a vacuum tapping tube inserted through port 10 in the cell roof 8 down through a bath supply passage 30 extending from an upper bath reservoir 7 into the sump. The bath reservoir may be fed periodically or continuously with the metal chloride through port 11 in the roof, and port 12 is for chlorine outlet above a bath return (gas lift) passage 35. As shown passages 30, 35 communicate with each space 19, being formed by holes (31, 36) and slots (32, 37) in the marginal edges of the superimposed electrodes, whereby the bath continuously circulates through spaces 19 and reservoir 7 by the chlorine flow. Each anode surface, preferably spaced less than ¥ inch from opposed cathode surface, has spaced channels therein for receiving and directing chlorine flow into the gas lift passage but not communicating with the bath supply passage. The cell refractory walls 3 lining the outer steel shell 1 may be nitride-based, e.g. a nitride of Si, B or Al (with or without oxide of Si, B or Al), or of Ti, Cr, Hf, Ga or Zr; silicon oxynitride (Si 2 ON 2 ) or Si 3 N 4  - bonded fused SiO 2  is preferred. A preferred bath comprises a molten solvent of 50-75% NaCl and 25-50% LiCl containing 1¢-10% AlCl 3  or 1¢-20% MgCl 2 . A mixture of AlCl 3  and alkali metal and/ or alkaline earth metal halide may be selectively condensed from the effluent gas and recycled to the bath. The chlorine recovered may be reacted with alumina to form AlCl 3  feed. Chlorine effluent (52), Fig.5 (not shown), containing alkali and alkaline earth metal and aluminium chloride may be cooled (53) to condense or sublime the chloride for recycling to the cell.

Abstract: 1,271,970. Controlling a plurality of processes. WESTINGHOUSE ELECTRIC CORP. 6 Aug., 1969 [22 Aug., 1968], No. 39332/69. Heading B1X. [Also in Division G3]  An analysis system for a plurality of process operations comprises control means determining the time interval for which an indication of each operating condition of the process is applied to the analysing means in dependence on the desired analysis. As shown, waste gas from a steel-making or arc furnace process 12 is supplied through a temperature control device 62, responsive to a temperature censor 60, and delivered at a controlled temperature through a filter 36, a flow meter 42, and a pump 38 to a valve 40 which feeds the waste gas to an analyser 78 or an analyser 74 for predetermined interval and at other times discharges to atmosphere through a conduit 70. The signals from the censor 60 and meter 42 are-fed to a programmed control computer 18 which both controls the carrying out of the process 12 and the operation of the temperature control device 62, pump 38 and the valve 40 whereby the waste gas is fed to each analyser 74; 78 for a time interval corresponding to their response time, the transport time of the waste gas being minimised by making the conduit from the valve to the analyser as short as possible. Additional processes, such as 10, are coupled to the analysers through valves, such as 30, the valves being sequentially operated by the computer in accordance with a programme. When one process has terminated its operation the related pump and valve are controlled so that the gas flow is not sampled from that process. The analysers may comprise gas chromatograph, infra-red absorption detectors for analysis of waste gas containing carbon monoxide or carbon dioxide, and electrical conductivity dew-point analysers. It is stated that the same waste gas may flow through both analysers 74, 78 and the computer programmed to ignore the reading of one or other of the analysers.
