Title: High capacity and velocity liquid vapour contact towers - having liquid distribution zones of V=shaped perforated channels and contact zones of similar form with sepn. zone of covered channels
Inventor: KULBE BERND DR ING
IPC: B01D3/26
Filed: 1979-02-03
Abstract: Gas-liq. contact device is formed from a series of phase contacting zones with subsequent sepn. zones. The liq. inlet zone has a series of individual elements which have a V cross section and inclined perforated side walls. These take liq. from a downcomer and entrain it in the gas stream. The gas and liq. then flow in counter-current through the contact zone which consists of a series of perforated plate elements of V section arranged across the flow area. The vapour leaves the contact zone and then enters the sepn. zone. Here the liq. is disentrained by separator elements consisting of covered V shaped devices mounted in rows across the cross sectional area. The liq. is taken by downcomer to the contact section below and the vapour proceeds up into the contact section above. For use in distillation, rectification, absorption, desorption or other liq./vapour mass transfer operations. Provides higher column throughputs and superficial operating velocities than conventional columns, more intense mass transfeR, low pressure drop and simple construction.

Patent DE-3020139-A1 (DE)
Title: Regulator for thyristor controlled reversing drive for DC motor - gives short time maximum current demand signal when changing from braking to running
Inventor: ZIMMERMANN HORST ING GRAD
IPC: H02P7/00
Filed: 1980-05-27
Abstract: The triggering of a particular bridge is under the control of a current regulator (5) which obtains speed dependent input signals (7). A supervisory circuit (8) determines direction of rotation, and whether inversion or rectification is required, in response to orders from the operator. If, after inverter operation, a drive instruction exists an additional signal is given to the current regulator. The supervisory circuit (8) connects (81) a biasing voltage (+U) to the current regulator. The magnitude of this voltage corresponds to full current output. This signal rapidly sets the regulator into the correct mode and is independent of the actual reference value of the ordered current. As soon as the rectifier gives a current output the biasing voltage is removed and normal operation resumed.

Title: Cleaning air by combined moisture and electrical field - to simulate natural self-cleansing properties of atmos.
IPC: B03C3/017
Filed: 1980-08-22
Abstract: In an appts. for cooling and cleaning air, the air is first moistened to provide ionisation, using water jets delivered by conductive components such as nozzles insulated from each other. The cleaning section has conductive filler bodies which are wettable, mixed with non-conductive bodies which are not wettable and contain electrodes subjected to high voltages, either DC or low frequency AC. The water and air are cooled in a counterflow heat exchanger located after the filler bodies in the air stream, and which may also be used to supply an electric field. Used for treating the air in living or working premises, hospitals, etc., to remove smells, germs and noxious materials. No new harmful materials are produced, as may occur with known systems, and the general aim is to simulate the natural self-cleansing properties of the earth's atmos.

Patent DE-3034227-A1 (DE)
Inventor: SAUMWEBER ECKART DR
IPC: B60T8/32
Filed: 1980-09-11
Abstract: An anti-lock device for vehicle brakes has a wheel generator which emits pulse-type signals whose frequency is proportional to the rotary speed of the wheel. A counter counts the pulses emitted during each of successive time intervals and these pulses are connected to a first memory which stores the count of the immediate preceding time interval and to a second memory which stores the count of the time interval next preceding the intermediate time interval. A logic circuit then produces a wheel speed value which is based on the wheel speed counts of the immediate preceding and next preceding time intervals.
