Title: Narrow cut cardboard or paper sheet stacking process - moves partial stacks sideways to bridge gap between adjacent columns
Inventor: VOSSEN MANFRED GEORG
IPC: B65H31/08
Filed: 1973-06-06
Abstract: The process is for stacking cut sheets of material, where the stack height is great in relation to the sheet surface area, the partial stacks which still have sufficient stability being joined by a transverse connection. Each time maximum stacking height is reached, the sheets in the next partial stack are thrust sideways far enough to bridge the gap between two previous partial stacks. This can be achieved by sideways movement of the platform on which the incoming sheets are deposited, when a number sufficient to form a partial stack have been counted.

Title: Socket with spring-loaded sliding cover over holes - has hooks engaging in recesses in rear of front plate
Inventor: OTTE GUENTER
IPC: H01R13/44
Filed: 1974-01-19
Abstract: The socket has a spring-loaded sliding cover which moves aside as the plug pins are pressed against its sloping outer face and allows the pins to pass through into the contact chamber behind the cover.

Title: Synchronising and balancing system for multichannel processors - divides channel signals into two parts to prevent interfering with processing
Inventor: DENKER RUDOLF
IPC: G01S3/02
Filed: 1974-09-26
Abstract: The synchronising and balancing system for aligning the phases, frequencies and amplitudes of channel signals in multi-channel processors etc., such as in direction finding equipment, has the high frequency signals divided into two equal parts: one part passes to the receiver and the other part to a n-pole switch. The switch connects the signals cyclically through to a reference oscillator for phase and amplitude comparison. The advantage lies in sampling the channel signals so that synchronisation and balancing do not interfere with processing etc. The channel signals may be divided into more than two parts as required.
