Title: Roof covering made from fabric - has spring loaded tensioning anchor at fabric lower edges
Inventor: LOSCH MAX HERMANN DR ING
IPC: E04H15/32
Filed: 1974-02-11
Abstract: The fabric roof is used for covering of sports grounds and for spectator stands. This roof is readily opened and closed. The fabric panels are tensioned to a minimum extent and the tension or compression springs used accommodate sudden high wind gusts by permitting the roof to flex and they damp out any disturbing flapping. The tensioning springs are connected between the guide rail and the top of the wall. The fabric lower edge is held in the guide rail by means of rollers. The helical spring has an internal length of wire rope which ensures that the spring is not stretched beyond a certain admissible extent. This rope thereby accommodates excessive forces and transmits them to the wall. The edge of the spring cover is held within the channel which is used as a rainwater gutter.

Patent DE-2536917-A1 (DE)
Title: Electronically controlled vehicle gear box - has amplified signal voltage proportional to speed and selector switch for manual operation
Inventor: STRAUB GERHARD ING GRAD
IPC: F16H61/02
Filed: 1975-08-19
Abstract: The electronically controlled vehicle gear box is manually or automatically operated. A signal voltage, which is proportional to the engine speed of revolutions is fed to an amplifier which in turn controls the gear change. The speed difference between a gear change upwards or downwards is such that a certain range of engine speed variation is tolerated when a gear change takes place. When the gear box is operated manually, the selector switch causes the two switch points for up and down gear change to shift above the normal position for automatic operation. This allows upwards gear change at any speed, but prevents a downward gear change if the engine speed is too high.
