Title: Ski safety fixing with limited retaining force - releases automatically under excess load to minimise danger to skier
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: A63C9/00
Filed: 1973-11-14
Abstract: The ski fixing attachment housing is fastened by a hinge to an underlying plate which is screwed to the ski. Two jaws pivoting on two pins have end contours to match the toe of the ski boot. The other ends of the two jaws have rollers which press against the stop which is held by the spring against the fixed pins. A nose piece forming part of the stop fits under a fixed stop. Under normal ski-ring conditions the force exerted by the spring keeps the ski and boot firmly together but any excess twisting or axial load pushes the stop backwards and releases the jaws.

Title: Damp-proof tube closure for tubular heating elements - has elastic sealing stoppers in ends of tube containing helical heating element
Inventor: LEUPOLD EUGEN
IPC: H05B3/48
Filed: 1974-03-02
Abstract: The damp-proof tube closure, for tubular heating elements, has the helical heating element axially inside the tube and attached at its ends to contact pins passing through insulating stoppers in the ends of the tube. The stoppers are elastic and slightly tapered so that they fit tightly into the tube ends and prevent the moisture entering the region around the heating filament. The heating filament is further completely sealed in an insulating matl. that occupies the whole of the tube. This structure reduces the number of stages required to manufacture such a tubular heating element.

Title: Safety switch with inserted sliding key - has pressure centre lever for protecting locking lever
Inventor: MERKLE PAUL
IPC: E05B29/00
Filed: 1974-06-19
Abstract: This lock has a longitudinally sliding lock insert and an intermediate lever whose horizontal arm forms the locking lever for the switch handle. The lock is provided with a pressure centre lever which ensures that the locking lever is rotated into its released position under a load and it displaces the lock insert in the end section of the outwards movement of the lock insert. The lock insert catch lever is actuated by means of the key tip section and rotated and the horizontal arm of this lever forms the locking member of this lever. The lock is provided with a pressure centre lever which is loaded by one or more springs. The lever releases the inwards movement of the lock insert only after a certain inwards directed sliding pressure has been exceeded.

Title: Rear safety frame for lorry - with warning contacts to activate alarm if obstruction met while reversing
Inventor: WALTER HELMUT
IPC: B60R21/34
Filed: 1974-12-10
Abstract: The rear of the lorry is fitted with a hinged frame (1) to support a steel braced flap (3) of rubber or plastic over the whole width of the vehicle. The flap is braced by a rigid frame (2) against which the flap is pressed if an obstruction is met while reversing. The bottom of the flap is arranged so that even if a child lies behind the lorry the flap is displaced. An electric switch (4) between the frame and the flap operates an alarm so that the driver can brake before causing injury. The system is simple and effective and covers the eventuality of children running behind the lorry after the driver has returned to the cab after checking the rear of the vehicle.
