Title: Welding double-walled plastics tubes
Inventor: STEINMETZ HANS WERNER
IPC: B29L23/00
Filed: 1993-06-30
Abstract: In a wild between tubular plastics members having projecting flanges 10, a welding element 20 having an embedded heating coil 22 is provided which softens parts of the plaster member remote from the flanges, while no significant melting of the flange ends occurs. In the described embodiment, the weld is between double layered plastics pipes. The inner peripheral surface 23 of the element rests on projections 10 of the tubular parts 1 and thus centers them. The welding element 20 has an annular core 21 with a heating coil 22 around at least part of it, for instance on outer contour. The heating coil 22 has coil strands laid in a zig-zag shape around the circumference of the annular core 21, or alternatively wound round its entire cross-section. The welding element 20 is wider in the axial direction than the spacing formed by the projections 10; hence at the start of welding there is a gap 13. Upon heating, the plastic softens around the heating element 22 but not at the projections 10; these therefore act as stops for the tube parts 1 as they are pressed together, and the joint is then allowed to cool. <IMAGE>

Title: Cryogenic processing of used tires and other materials
Inventor: ZUWALA STANLEY MICHAEL
IPC: B02C4/02
Filed: 1993-10-05
Abstract: Old tires are cut into strips (49), cryogenically cooled in liquid nitrogen (60) to make the rubber brittle, and the frozen strips fed through a pair of pinch rollers (50A). One of the rollers has a grooved and knurled surface. The rollers are pushed together by hydraulic rams; the pinch force is large enough to shatter the surface of the rubber, but small enough to leave the bulk of the strip intact, and the pinch force remains the same even if the thickness of the strip varies. The strip passes progressively through successive pairs of rollers, each time the surface of the strip is shattered and the fragments fall clear. With this treatment, the steel wires and textile cords in the tire separate or delaminate very easily, and without being crushed or damaged. All the components of the material composite are recoved and separated for recycling. The rubber crumb thus separated is treated with a suitable chemical treatment for breaking down the molecular cross-links, mixed with plastic material and then repolymerised. <IMAGE>
