Title: Cabinet with mechanically movable carriers - carriers can only move when slidable door is in correct open position
Inventor: LEXE WERNER
IPC: A47B63/06
Filed: 1974-09-19
Abstract: The cabinet with mechanism is especially for housing documents. It has a number of carriers which are sequentially movable to an access opening by mean of a driving mechanism. A slidable door, in parallel with the direction of the carriers, can close the access opening. A safety mechanism formally keeps the slidable door in its open position at a prescribed distance from its final position. A switching device turns the driving mechanism off when the slidable door is moved within the safety range. A control device for the switching ensures that the driving mechanism can only be effectively operated when the slidable door is in the normal open position.

Title: Chatter reducing machine tool drive - uses steplessly adjustable electrical drive which superimposes speed variations on drive
Inventor: DRESEN KLAUS
IPC: B23Q11/00
Filed: 1975-05-10
Abstract: A continually and periodically varying voltage (Us) is superimposd on a nominal voltage which corresponds with the nominal speed of the machine tool work spindle.

Title: Gearbox for transmission of high powers - uses parallel gear trains of bevel, helical and straight form
Inventor: BENTHAKE HEINRICH DIPL ING
IPC: F16H1/22
Filed: 1975-10-02
Abstract: The input shaft (1) drives a layshaft (18) at the same speed, via straight cut gears (4, 5). The shafts (18, 19) then drive two parallel gear composed of bevel gears (2), 7; 3, 6).
