Patent DE-2734205-A1 (DE)
Title: Disinfecting operating theatres by inflammable aerosols - uses electric wiring with common external terminal for all consumers, except atomiser, which is disconnected during atomiser operation
Inventor: WENZEL-EDEN HELMUT
IPC: A61L9/14
Filed: 1977-07-29
Abstract: The process for disinfecting operating theatres uses an alcohol-based inflammable aerosol. All electrical appliances in the theatre, apart from the aerosol atomiser, are fed from a common supply terminal outside the theatre. This terminal is disconnected by a time switch, at least when the atomiser is operative. All openings into the theatre, e.g. for air-conditioning, are gas-tightly sealed by mechanical members controlled by the time switch. The theatre atmosphere is finally extracted through an absorption filter.

Title: Etching plant, useful in mfr. of e.g. printed circuit boards - where plate to be etched is stood in an inclined position on a grating so that fluid flows uniformly over plate
Inventor: KRAUSE EMIL
IPC: H05K3/06
Filed: 1977-08-13
Abstract: Etching plant for use in operations for printed circuit boards (PCB) has no moving parts to move the PCB's past the stationary nozzles and runs no risk of the nozzles becoming clogged. A tank is subdivided into a storage section for the etching fluid above a heating unit, with a pump which delivers the fluid to a channel along one side of the other part of the tank. The PCB stands at an inclined position on a grating so that the fluid flows over a groove uniformly over the board. An inclined bottom below the grating returns the fluid to the storage tank.
Patent DE-2747543-A1 (DE)
Inventor: RUDIN FRANZ
IPC: B01D46/08
Filed: 1977-10-22
Abstract: The filter hood (4) is fixed by its open end at the orifice edge to a filter frame (1). The other filter hood end is configured in such a way that a self-supporting cantilevered hood is formed. For this purpose, a star is formed so that each two neighbouring web sections along a rim edge (5) are joined together as a seam (17). The filter hood is composed of one rectangular filter web material piece, from which the hood is formed without waste. Folding lines (15) and seam sites (16, 17) are present. By means of the reentrant corners (6) in the star, the desired stability of the hood and at the same time an advantageous conical shape of the hood are obtained, so that a plurality of adjacent hoods do not abut each other. <IMAGE>

Title: Two-component resin mixing ratio control - by metering pump delivery pressure sensors detecting pressure rise delays
Inventor: BAUR PETER DIPL ING DR
IPC: B01F15/04
Filed: 1978-03-21
Abstract: The mixing ratio is controlled by a pressure sensor downstream of every metering pump. Any time shift in the attainment of a set presure relative to that in a master pump is determined and in case of discrepancies a warning signal is sounded or the plant is shut down. Any defective function of a metering pump or the absence of one component is easily spotted and remedial measures can be taken at once. The two resin components from the storage containers are passed by metering pumps through non-return valves to a mixing tank. Pressure sensors check any time delay between the pressure built up in the line of one component relative to the other component which is considered as the master.
