Title: Semiconductor storage device for multistable voltage steps - accelerates carriers taking electrons to higher energy levels
Inventor: SCHROEDER WOLFGANG DIPL ING
IPC: H03K3/36
Filed: 1973-05-25
Abstract: A system for generating multistable voltage or current steps uses a controllable potential difference which is placed onto two electrodes of a semiconductor device. This accelerates the charge carriers which take atoms, group of atoms or their electrons through quanta of energy steps to different energy levels. This causes a loss of velocity in the carriers concerned and this is used as the parameter for regulating the potential difference between the two electrodes. The electrodes are those of a transistor device and are separated by a barrier layer. The base electrode is used as the accelerating electrode and is fed via a resistor. The system is built up as a monolithic semiconductor integrated circuit.

Title: Safety fixing for ski-shoes - has position sensitive release system which required only light force to function
Inventor: KLUSCH SIEGFRIED
IPC: A63C9/08
Filed: 1974-01-08
Abstract: The safety fixing is intended to prevent dangerous forces being exerted on the skier's leg. This is achieved with a release system that is operated by an adjustable pre-set load, which with the help of a retaining device which grips the heel and toe or the centre of the ski-boot releases the whole of the ski attachments. The pre-set load can be controlled by a pre-tensioned spring, compressed gas or by driving members which can be released by means of removable stops, shear pins or an electric fuse system. These devices, which require only a relatively small operating force, may be supported by position sensitive and delay sensitive release devices.
