Patent DE-2601775-A1 (DE)
Title: Vehicle safety belt to ignition system connection - has solenoid on belt latch to block ignition by preventing use of ignition key
Inventor: BAUER HANS
IPC: B60R22/48
Filed: 1976-01-19
Abstract: The electro-pneumatic and mechanical lock for a car ignition key system is released by engagement of the driver's safety belt. The ignition key system is so locked by the pins and a spring with linkages that the ignition key cannot engage and the engine cannot be fired. This is possible only when the engagement head of the safety belt is engaged in the catch. The solenoid operates via a current pulse from the contact of the catch via the battery so that the pins release the ignition switch system via the linkage.

Title: Veneer sheet cutting bench - has cutting blade across end and second blade along side
Inventor: LARSEN VIGGO FREDE EVALD
IPC: B27L5/08
Filed: 1976-04-09
Abstract: An arrangement for cutting veneer sheets has a bench on which is placed a stack of veneers which are cut first across the grain by a guillotine at one end of the bench, then with the grain by a second guillotine at the side of the bench. Extensions of the bench surface behind the cutters receive the offcuts. By bringing the two cutters together at the same bench, the stack of veneers is brought quickly and easily from one cutter to the other, without risk of the loss of alignment that can occur with cutters placed farther apart. If both ends of the veneers are to be cut, a second cross-grain cutter might be placed at the other end of the bench.

Patent DE-2747411-A1 (DE)
Inventor: WADA TOMIO
IPC: G09G3/18
Filed: 1977-10-21
Abstract: The device is suitable for display panels in electronic units for representing different operating states. It consists of a cell (7) filled with a nematic liquid crystal (5) which exhibits negative dielectric anisotropy. The cell (7), which is produced in a sandwich design, has a pair of transparent conducting electrodes (3, 3'). The liquid-crystal molecules are aligned with their longitudinal axis perpendicular to the electrodes (3, 3') by means of a surface-active substance. If an alternating electric field with a frequency lower than a threshold frequency is applied to such a display device, the liquid crystal can be excited to dynamic scattering of light, while when an electric field with a frequency higher than the threshold frequency is supplied the crystal is excited to birefringence of light. In this case, the threshold frequency is in the lower audio frequency range. <IMAGE>
