Title: Bank vault intruder alarm system - maintains overpressure inside enclosure and has electrical switch responding to pressure changes to actuate alarm
Inventor: KOWOLLIK JOSEF
IPC: B60R25/10
Filed: 1977-07-01
Abstract: The break-in alarm system is for use with enclosed spaces, e.g bank vaults, safes, data stores, cars, etc. The enclosure is made air tight and an overpressure of underpressure is maintained in it by a compressor. The compressor may be situated inside the enclosure and be connected to the external air by a suction pipe. Alternatively the compressor may be mounted outside the enclosure. It acts together with a control device which measures the pressure within the enclosure. An electrical switch responds to changes in pressure within the enclosure to actuate an alarm. In the case of a car the compressor may be the air blower of the air conditioning system.

Title: Tower for separating solids from salt solutions - sprays liquid upwards in hot air current, larger particles being collected below
Inventor: MANZ ROLF DR ING
IPC: B01D1/18
Filed: 1977-11-11
Abstract: The vessel for separating salts from a liquid salt solution is a vertical tower with a parallel sided, lower part which transforms into an outwardly sloping upper part.

Patent DE-2803332-A1 (DE)
Inventor: ALTMANN JOSEF DIPL ING
IPC: G05D7/01
Filed: 1978-01-26
Abstract: The actuating device has an outer casing (1), an inner casing (11) in the latter and a regulating element (23) mounted between two bellows (2,3). Different pressures of the liquid system to be regulated are applied to the two end faces (231,232) via different inlets (200,201). The pressure difference then produces a displacement of the regulating element (23) relative to a fixed wall (10) and hence the formation of an annular gap, the width (z) of which depends on the pressure difference and thus regulates the quantity of liquid flowing through the device. This actuating device is suitable, in particular, for regulating the flow of heating steam drains in the regeneration system of a turbine.   <IMAGE>
