Title: Conveyor belt moved sheet transfer device - to assist sheet movement from conveyor to gripper installation
Inventor: MATTLE HERBERT
IPC: B65H9/16
Filed: 1973-10-10
Abstract: Sheet transfer installation used for sheets individually conveyed on a conveyor band and moved at varying intervals and without being lined up along a side edge to be transferred to a gripper system which can only handle sheets in regular succession.

Title: Coin-operated gaming machine - has multi-position difference counter comprising individual electro-mechanical pulse counter decades
Inventor: KUBATSCH GUNTER
IPC: G07F9/08
Filed: 1974-02-05
Abstract: The lifting magnet of the low value decade obtains voltage during the transition of the counter wheel from zero to nine via a contact only if the contact is closed by the lifting magnet as the carry of the associated higher value decade takes place. The safety circuit between the units and the tens decades is made ineffective via a contact by another contact which is closed when the coin is returned. An arrangement of contacts and cam paths prevent the low-value decade from continuing to count, if the higher decade has not been operated during the carry.

Title: Retracting headlamps for car - with extra linkage effective in dead points of servo drive
Inventor: EYB WOLFGANG
IPC: B60Q1/06
Filed: 1974-02-15
Abstract: The headlamp unit is raised from a streamlined, retracted position into the operating position by means of a servo motor and a lever linkage. This restricts the amount of movement of the lamp, with the linkage reaching a dead point. At this point a special linkage automatically comes into operation to move the lamp further and thus extend the lamp movement over the normal dead point. The lamp can thus be moved from a fully retracted to a fully extended position using a simple linkage. The mechanism can include a spring for assisting the lever past its central dead position.
