Patent DE-2620117-A1 (DE)
Title: Liquid discharge system from containers - prevents oxygen absorption by vacuum responsive changeover of discharge valves
Inventor: LEIPOLD DIETER
IPC: B67D1/04
Filed: 1976-05-06
Abstract: A control system for the continuous discharge of fluid such as beer from several containers in turn has in the discharge pipe from each container a non-return valve and a pneumatic control valve. When the non-return valve in one line closes, thus indicating that this container is empty, the resulting negative pressure is sensed b y a differential manometer. This closes the pneumatic control valve in the pipe from the empty container and opens the valve for the next full container. This prevents the rise of the O2 index in the beer when changing from an empty to a full container which would affect the taste of the beer. The device can be readily added to existing filling plant.

Title: Contact etching process for integrated circuit production - has exposed monocrystalline silicon converted to N-type conductivity by ion implantation
Inventor: STUERMER ANTON DIPL ING
IPC: H01L21/3213
Filed: 1976-05-29
Abstract: A contact etching process can be used in the manufacture of integrated circuit elements. The manufacture is performed by etching out printed wiring from a polycrystalline silicon layer which has been separated from a monocrystalline silicon substrate. The process uses a liquid etching agent. The exposed monocrystalline silicon in the windows of the photolacquer masking layer is converted into n type conductivity before applying a cover sheet of polycrystalline silicon of p type conductivity. The conversion of the conductivity is achieved by implantation of phosphorous or arsenic ions.
