Patent DE-2702666-A1 (DE)
Inventor: ROELLECKE HUBERT
IPC: H02H3/093
Filed: 1977-01-24
Abstract: It has been known to connect an accurate and thus expensive rms value measuring system for the relay to each phase of a multi-phase system which feeds a load protected by an electronic overcurrent time-lag relay. This is necessary because the current curve deviates from the sinusoidal shape in static-converter fed systems and the rms value of the phase currents must therefore be detected by measuring techniques. To reduce this effort, a monitoring circuit arrangement consisting of differential amplifiers (1, 2, 3), storage capacitor (29) and output switches (30, 31, 32) for the phase currents is used which switches the highest phase current value in each case through to a common output (UA) of the monitoring circuit arrangement to a single rms value measuring system. <IMAGE>

Patent DE-2749186-A1 (DE)
Inventor: PUTTFARCKEN ULF ING GRAD
IPC: A47K5/12
Filed: 1977-11-03
Abstract: The outlet valve has an annular space (11) into which a feed line (6) opens out. A throttle cylinder (10) is arranged between a plunger (3) mounted in the annular space (11) and a sealing plunger (7) which can be moved into an outlet aperture (4). The pressure of the inflowing cleaning agent, e.g. soap, raises the plunger (3) and thus the sealing plunger (7); the outlet aperture (4) is exposed. During shut-off, a spring (9) presses the plunger (3) downwards. As a result, the sealing plunger (7) again enters into an outlet channel (12) and scrapes its walls free from dried-on residues. The throttle gap (8) stores the cleaning agent until it can flow without splashing through the substantially larger outlet aperture (4). <IMAGE>

Title: Drum filter for purifying liquids - having paper medium laid onto continuous support belt with exposed portion above liquor level to dewater cake by drawing air through
Inventor: HOLZHEY DIETER ING GRAD
IPC: B01D33/00
Filed: 1978-09-23
Abstract: Solids are sepd. from liquids by a rotating perforated drum onto which a paper filter medium is laid. Filtration is achieved by subjecting the inside of the drum to a reduced pressure and forming a cake on the outside of the drum.
