Title: Automatic sales machine for large packages - depends on pneumatically operated gates and can accept boxes of empty bottles
Inventor: SCHANZ THEODOR
IPC: G07F11/16
Filed: 1973-09-07
Abstract: The machine automatically sells larger packages, specifically boxes of bottles. The boxes are stored in a magazine and released to fill two buffers, one of two boxes and one of one box, this being near the front of the machine. All three boxes in the buffers sit on a ramp sloping towards the front of the machine and extending out of the front of the machine to form a service tray. Doors prevent the boxes sliding out on to this service tray. These doors are operated by means of pneumatically driven pistons, which are actuated in sequence by a coin being inserted and found to be genuine by a coin checking mechanism. The front box slides on to the service tray and a further sequence closes the door and allows a further box to slide forward into the forward buffer position from the back buffer position.

Title: Control for electrically driven centrifugal compressors - prevents pumping of the compressor when the motor current exceeds a max. value
Inventor: BAUR JUN PAUL
IPC: F04D27/02
Filed: 1973-09-29
Abstract: The compressor has an adjustable bleed valve in the outlet pipe which is electrically operated. The current of the compressor drive motor is measured and a signal is generated which is proportional to this current. The proportional current is compared with a predetermined min. value. A modulated control signal is generated which is a function of the amount by which the proportional current is less than this min. value. This signal is fed to a control arrangement which opens the bleed valve in the exhaust and closes it again when the proportional signal exceeds the predetermined min. value. The control arrangement also incorporates a current-pressure converter which generates an air pressure signal which is proportional to the current and which is also used in the bleed valve control arrangement.

Patent DE-2441962-A1 (DE)
Title: Protection of thyristor inverters against commutation failure - involves making gate signal dependent on reverse voltage duration
Inventor: OGATA FUMIO
IPC: H02H7/122
Filed: 1974-09-02
Abstract: The application is to both series and parallel connected thyristors, and is intended to guard against the adverse effects of commutation failure, principally a failure caused by short duration blocking voltages followed by forward voltages. If this time is short not all thyristors will turn off and those remaining in the conducting state will carry excessive current and may be damaged. The effect is guarded against by ensuring that the gate power remains applied to the thyristors that should be commutating until the duration of the reverse biasing voltage has exceeded the time in which all the thyristors will have turned off. Thus the appearance of a forward bias during this time will turn the devices on again causing them all to share the current.
