Title: Inward-retracting mould segments shaping a pipe socket end - cut away so as to retract into smaller space
Inventor: DELARUE WALTER
IPC: B29C45/44
Filed: 1976-09-21
Abstract: The socket end is formed by dilating the softened thermoplastic pipe over a profiled arbor which forms the inner surface of an annular mould, fresh material being added meanwhile. The part of the mould surface that makes a groove inside the socket rim is a segmented circle, whose parts retract inward (into the arbor) after use and rest as two rings of segments, with the segments of the outer ring overlapping those of the inner. By the invention, the ends of the segments of the outer ring are cut away, so that these segments can retract closer to the axis of the arbor. This more compact packing allows the method to be used for pipes of smaller dia.

Title: Hydraulic control safety system to two-speed hydraulic press - stops descent of slow piston if any control valve jams
Inventor: KUTTRUF WERNER
IPC: B30B15/28
Filed: 1976-10-29
Abstract: A safety control circuit is intended for a hydraulic linear motor, esp. of a hydraulic press. The linear motor comprises a fast cylinder and a high-load cylinder, each regulated by hydraulic control valves, to enable the upper chambers of the cylinders to be connected to the power source while the lower chambers in the annular space surrounding the piston rod are connected to the return oil line, or vice versa. The main control pistons of the two control valves each comprise three switching positions, the paths through these valves are connected to the pressure oil source and the fast cylinder and/or the load cylinder and return line in such a way that, if one of the main control pistons sticks, the downward movement of the piston in the load cylinder is blocked. Greatly increased safety is achieved without the use of limit switches and other devices which can fail. As a consequence, the two-speed hydraulic press is suitable for hand operation since injury to the operator is virtually impossible.

Title: Low friction running surface for ski - is applied by adhesive strip with coating of wax to suit snow temperature
Inventor: BECKER HERMANN
IPC: A63C5/04
Filed: 1976-12-03
Abstract: The running surfaces of skis, used on cross-country skiing, are coated with wax in order to reduce friction to a minimum. But the type of wax used varies according to the temp. of the snow and so must be changed during long races with changing weather conditions. To facilitate this change of wax coating, the wax is applied to a backing strip of aluminium foil, or synthetic fibre or suitable paper. The other side of the backing strip is coated with adhesive and covered with a protective film. The filmis removed and the backing strip applied to the undersurface of the ski. If necessary one backing strip with a different type of wax can be stuck to a strip already on the ski.
