Abstract: 528,677. Cables. SOLUTION TRUST, Ltd. March 2, 1939, No. 6829. Convention date, March 2, 1938. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 18, 1939.] [Class 36] In a cable of the type having a central core separated from a metal sheath by powdered mineral insulating material, the material is calcium oxide or analogous mineral insulation which, on exposure to the atmosphere, retains higher insulation resistance than powdered magnesia in similar circumstances. Numerical values of comparative " limit insulation resistance " are given. The effect is attributed in part to swelling and in part to formation of a carbonate skin, both tending to exclude further ingress of air. A mixture of calcium oxide-and magnesia may be used.

Title: Method and apparatus for producing a hollow body
Inventor: ARNOLD WOLFGANG
IPC: B65H81/00
Filed: 1970-02-13
Abstract: 1294199 Manufacturing hollow bodies W ARNOLD 13 Feb 1970 [14 Feb 1969] 7094/70 Heading F2P  In manufacturing a hollow body, a strand of material which will stick to adjacent windings of itself is helically wound to produce a hollow body of varying cross-section and the so formed body is simultaneously and continuously rotated and longitudinally displaced. Suitable apparatus includes devices for supplying the strand, for depositing it next to the preceding winding, a drive mechanism for rotation and axial movement of the body and a device for varying the cross-section of the body. The strand may be a glass fibre coated with thermosetting resin, an extruded thermoplastics or an adhesive covered material. In the embodiment shown the strand 4 is fed on to rollers 35 which are diametrically opposed and radially adjustable by means of sliding clamping jaws 31 located on receiving plate 30. The rollers 35 rotate about their horizontal axis by means of a drive from a variable geared engine 44 via wheels and belts 43, 42, 41, shaft 40 and wheel 39 which powers V-belt 37 running between wheel 39 and counterbearing 38. Belt 37 also powers rollers 35 via wheels 36a, 36b, 36c. Rollers 35 are inclined by rotation of wheel 50 which moves disc 45 and thereby bearing 34 drops into a groove on the shaft 46. Additional strands 4b, 4c 4d may be applied, the feed point b-b for 4b being variable. A layer of foil 66 may be applied from reels 21 mounted on rotating ring 20. Additional support for the hollow body is provided by spring arms 53 fitted in sleeve 51. The hollow body is advanced by belts 11 engaging its internal surface powered by motor 27 through shaft 27, gear-box 26, spindle 6 and wheels 8a, 8b, 8c. Axial movement of spindle, 6 varies the position of the belts 11 which are retained and forced outward by spring 12 and rotated by shaft 2. The free end of the hollow body is attached to cone shaped member 14 mounted on moving carriage 16.  Alternatively (Fig. 4, not. shown) an air expandable diaphragm attached to movable coaxial discs 96, 97 may vary the cross-section of the body by means of a roller 102 following rotating cam 100 and transmitting its movement to synchronous gears 103, 103<SP>1</SP> which alter the axial spacing of discs 96, 97 and may control the air supply to the diaphragm. The longitudinal axis of the hollow body may be vertical, the strand being'supplied by falling under gravity (Fig. 5, not shown). In another embodiment the strand is extruded on to a rotating disc 68 which descends through aliquid coolant which hardens the thermoplastic strand. In another (Fig. 6, not shown) inclined rotating rollers 69 engage the outer surface of the wound hollow body and rotate and vertically displace it.
