Title: Shock absorbing mounting frame for high tension switch gear - uses inflated tyre as pneumatic damping element
Inventor: PICARD KARL-HEINZ
IPC: F16F15/023
Filed: 1973-09-28
Abstract: The mounting frame of a switch gear base carries horizontal shaft which are located in the centre of wheel rims. Each rim is fitted with an inflated tyre which rests on a concrete foundation. A semicircular sheet metal cover is used to clamp each tyre to its foundation. The tyre pressure which can be automatically monitored, is such that the supported load is in a floating state. Under this condition, the air under pressure in the tyres prevent the vertical or horizontal vibrations which are set up by an earthquake, from reaching the switch gear apparatus.

Title: Connection method for bunch of wires to cct. board - uses tank in which liquid solder rises
Inventor: THUMM HANSPETER
IPC: H01R43/02
Filed: 1973-10-19
Abstract: Connection is made in following steps: wires from the bunch are pushed through holes in the plug board and printed circuit board, so that all contacts and connection points to be soldered lie in a plane; the temporarily connected parts are placed over the solder tanks, with the contact plane facing the tank; solder then fills the tank to and above the contact surface, and after a timed period is allowed to escape while the soldered parts are lifted by rotation about an axis lying in the contact plane. Should unacceptable drips or bridges be left the workpieces can be returned immediately for re-processing without the need for new molten solder.

Title: Non removable fitting for duty disc on number plate - with adhesive fitted securing ring and spring plunger to break disc if plate removed (NL220676)
Inventor: ZEITZ ROLF
IPC: F16B41/00
Filed: 1974-12-20
Abstract: The duty disc is formed by a plastic pressing (9) which is secured inside a metal housing (2) by means of a metal rim (12) and layers of adhesive (13).

Title: Conveyor with rail guided and powered wagons - uses accumulator and electronic control to negotiate gaps in rail for current pick-up
Inventor: KARDINAL HANS-JOACHIM
IPC: B60L9/00
Filed: 1975-04-15
Abstract: The electric vehicle is fitted with a set of wiper contacts (K1, K2) which pick up current from the rails (S1, S2) and drive the motor (M). At the same time an accumulator (A) is constantly charged via a current regulating circuit (R). If the vehicle passes gaps in the conductor rail, or if ittmoves from one track to another, without requiring complex switching, then the accumulator provides sufficient power to drive the vehicle independently. An electronic control circuit (ES) ensures a regulated power supply to the motor. Current can be drawn from the accumulator to boost the motor torque for starting or for ascending inclines etc.
