Title: Scotch for immobilising heavy vehicle - has jaws attached to wheel fixing to grip tyre side in conjuction with wedge
Inventor: THIEBAULT ROBERT
IPC: B60R25/09
Filed: 1974-07-26
Abstract: The scotch consists of two jaws, one external and one internal, hinged together and locked together with an arm covering the wheel fixing details. There are means of locking the jaws by tamper-proof fixings. There is also a wedge device pressing on the ground on a curved face, between the tyre on the wheel to be locked and the jaws to prevent the wheel rolling or slipping on the road. Jaw arms pivot on the ground, so causing the jaws to become detached and so freeing the wheel. The jaws are L shaped, with parts pressing on the tyre sides, but not on the wheel rim.

Title: Decorative component - comprises glass tiles glued to cloth base whose thicker edges protect tile edges
IPC: B44C3/12
Filed: 1974-11-05
Abstract: The component comprises a strip of small tiles, particularly of stained or reflecting glass (5), placed edge to edge and rectangular or square in shape. These are glued to a suitable base of cloth, jersey fabric, felt etc., which is flexible and easily stretched and of some softness, and whose edges are of a thickness equal to that of the tiles so as to cover the edges of the latter. Thus the tile edges are protected from damaging shocks, and prevented from cutting other things. The tile edges can be chamfered and they can be from 1 to 2mm thick.

Title: Joining large diameter plastics pipes - using synthetic resin and hardener contained in joining band
IPC: F16L13/10
Filed: 1976-11-18
Abstract: When joining lengths of large diameter plastics pipes it is difficult to measure the correct quantities of constituents required for the adhesive.

The middle section (1) is in the form of a sandwich with a filling of synthetic resin. The undersurface of the section (1) is perforated so that when it is wrapped around the pipes (5)(6) the perforations face outwards. The last section (2) is a sandwich containing the hardener and with perforations on the upper surface. When the strip is in position, the hardener passes through the perforations to make a sound joint.

Title: Self adjusting hydraulic disc brakes - with backflow limiting valve to generate constant brake pedal play
Inventor: SCHWABE JURGEN
IPC: F16D65/74
Filed: 1976-12-03
Abstract: The hydraulic operated disc brakes are linked to the master brake cylinder by a hydraulic control valve in a separate housing.
