Title: Method of lining pipes moulds or other tubular articles
IPC: B29C41/00
Filed: 1972-09-14
Abstract: 1444225 Lining pipes ENGLISH CLAYS LOVERING POCHIN & CO Ltd 13 Sept 1973 [14 Sept 1972] 42785/72 Heading B2E [Also in Division F2] A method of lining a pipe or other tubular article with a thermosetting synthetic plastics material comprises arranging the pipe with its longitudinal axis inclined to the horizontal, delivering the material in liquid form into an upper part of the pipe so that it flows along a length of the pipe, the pipe being held stationary while the material is introduced, shifting the pipe to a position in which its longitudinal axis is horizontal and spinning the pipe about its longitudinal axis until the material has set. The liquid material is introduced into the pipe at a constant rate and the angle of inclination is such that the material first introduced into the pipe flows to a predetermined lower part of the pipe in the same time for completing the introduction of the amount of liquid required to line the pipe. The pipe may have end flanges and covers may be fitted to the flanges to prevent the liquid material flowing out of the pipe during spinning. The covers may be spaced from the flanges to provide annular spaces into which the material may flow so that the lining extends radially at each end of the pipe, (Fig. 3, not shown). The pipe may be of metal e.g. steel which is first cleaned and then coated with a suitable bonding agent. The lining material may be a polyurethane. The pipes may be spun by means of driven rollers. To remove any entrained air bubbles in the lining material a blast of hot air may be 'blown through the pipes.

Abstract: 1384687 Unwinding continuous strand BRITISH INSULATED CALLENDERS CABLES Ltd 22 June 1972 [23 March 1971] 45298/70 Heading D1J To unwind a continuous strand stored in two coils, the strand of the first coil is withdrawn via an overhead carriage which is moved over the second coil when the withdrawal movement of the inter-coil strand length is sensed, and the carriage is returned with the second coil to the first unwind position. Strand W, Fig. 1(a), is withdrawn via carriage-mounted guides 5, 8 from coil 2 on conveyor 1. When strand length 17 is lifted switch 11 is operated via hook 10 to move the carriage over the next coil, Fig. 1(c). The carriage and coil are then moved back to the first unwind position. Tubular members 6, 7 limit strand ballooning. Alternatively, Fig. 2, strand W is unwound through carriage-mounted flexible tube 25 which rotates with the ballooning of the strand and which is deflected by the inter-coil strand length to actuate switch 30 to move the carriage. The movement of the conveyor to carry the second coil to actuate switch 29 to the first rewind position causes the running strand to deflect the tube to return the carriage. The tube may comprise a coiled spring or a rubber or plastics tube. Alternatively, the tube may be a member deflectable only in a plane containing switches 29, 30. A train of coils may be so unwound. The carriage may be moved by a pneumatic or hydraulic jack, or by an electric motor.
