Title: A method and apparatus for stranding a quad of a communication cable
IPC: H01B13/02
Filed: 1969-04-30
Abstract: 1,249,367. Stranding machines. SUMITOMO ELECTRIC INDUSTRIES Ltd. 30 April, 1969 [11 June, 1968; 6 Nov., 1968], No. 22103/ 69. Heading D1T. [Also in Division H1] In order to minimise capacitance imbalance between pairs of a quad 19 of a communication cable, periodically increasing and decreasing twists are imparted to the wires along their length by opening and closing torsion brakes 21-24 which alternately permit and prevent rearward transmission as far as backtension devices 13-16 of the twist imparted by the take-up device 20. Wire pay-off devices 9-12, lay plate 17 and die 18, for forming the quad, complete the arrangement and are all stationary in space as are the brakes and tensioners. The brakes preferably close simultaneously on wires, at opposite corners of the quad and remain so for the passage of a wire length of about 4L, after which they open for a similar period. The operation of the other pair of brakes is delayed relative to the first by the equivalent of 2L (Fig. 7 not shown). Slack in the wire caused by the operation of a brake may be taken up by a dancer roller (42 Fig. 8 not shown) operated by a cam (40) synchronised with the cam (36) operating the torsion brake. In a further embodiment (Figs. 10 and 11 not shown), the twisting is produced by a flyer rotating about the take-up device and the quad is divided by a second lay plate (49) which rotates in the same direction as the flyer but at twice the speed and is of special design (Figs. 12 not shown). A second die (50) rearranges the wires into quad (55) which is taken up via torsion detecting roller (53).

Abstract: 387,378. Leather board. PRESTON, E. F., and STOWE, D. and STOWE, L., (trading as STOWE & CO.. E.), 14, Milton Road, Stowmarket, Suffolk. Aug. 4, 1931, No. 22127. [Classes 96 and 140.] Leather board is made by reducing scrap leather to a pulp in water with a suitable adhesive, pressing the pulp to form a core sheet, and then interposing the core sheet between sheets of leather secured thereto by adhesive and pressure. The apparatus comprises a feed table 1, Fig. 1, from which scrap leather is fed over a sieve 2 and a magnetic separator 3 to remove dust and metal scraps, to a cutting machine 4, and thence into a beater or pulping machine 5 where it is reduced to pulp in water. The pulp is mixed with adhesive in a tank 6, and pumped to a vat 7 containing a revolving gauze drum 8 upon which it is deposited. The deposit is removed by an endless blanket 9 of felt or like material held against the drum 8 by a weighted roller 10. The blanket picks up the sheeted pulp and carries it between pressure rolls 11, 12. The pulp collects on the roller 12, from which it is stripped by known means on to a table 22. The sheet of pulp is then coated with adhesive, such as a solution of boiled starch, placed between two leather sheets and pressed to form a composite board. The roller 12 may be fitted with an electrical device for indicating when sufficient pulp has collected thereon. The roller 12, Fig. 2, is floatably mounted, and a metal rod 24 resting on the axle of the roller slides in guides 26. Above the rod is a pointer 29 held down by a spring against an adjusting screw 32 by which it may be set to indicate the desired thickness on a scale 30. When the roller 12 has collected the desired thickness of pulp, the rod 24 is raised to make contact with the pointer and complete a circuit including a lamp 28. A water spray 16, Fig. 1, and brush 17 may be provided for cleaning the drum 8. Waterproofing material such as latex may be sprayed on to the pulp on the felt from a spray 21. The blanket 9 may be cleaned by being passed through a bath 18 and dried by beaters 19 and rollers 20.
