Title: Neutralisation/polarity reversion of permanent magnet assemblies - rotates individual magnets or duplicated assembly of opposite flux direction
Inventor: PERKUT BRANCO R
IPC: B23Q3/154
Filed: 1973-09-22
Abstract: The arrangement for execution of magnetic forces on an object (magnetic gripping chuck) consists of a multitude of permanent magnets each having a N- and S-pole and so arranged that in each pair adjacent magnets adjacent poles have the same polarity. The object to be subjected to the magnetic force for attraction is brought in effective range of all the adjacent pole pairs with equal polarity. To obtain a magnetic neutral position with diminished attraction or even to reverse the polarity (as for objects with high magnetic remanence) the polarity of at least one pair, preferably of all pairs, is interchangeable. This is achieved by both magnets of a pair being movable between two positions of opposite polarity.
Patent DE-2350291-A1 (DE)
Title: Desorption of gases from activated coke granules - by indirect heating in spiral channels
Inventor: LACHNIT FRIEDRICH DIPL-ING
IPC: C01B31/08
Filed: 1973-10-06
Abstract: Spent coke granules from wast gas or water treatment is reactivated by passing through an externally heated channel. The granules are mixed at regular intervals by changes in the shape of the channel surface which cause rolling instead of sliding. This stirring, together with the fluidising effect of the desorbed gases gives hight heat transfer rates. As the carbon is heated from 100 degrees C to 180 degrees C steam is desorbed. Desorption of SO2 at about 180 degrees C is suppressed by automatically controlled pressure to give 1-3 ppm until the steam is desorbed. This pressure is applied to offset the pressure drop due to the resistance to flow of steam through the coke. Fractional desorption gives nearly pure steam suitable for use in a Clausius plant. H is unnecessary to introduce hot sand (which must later be sepd. and washed) or hot gas (which may react with the coke or desorbed gases) into the coke.

Title: Hydraulic transmission for road vehicles - uses triple rotor sliding vane motor to provide three speed drive
Inventor: KEMPER HEINZ
IPC: B60K17/10
Filed: 1974-03-16
Abstract: The hydraulic sliding vane motor has three identical rotors mounted on a common shaft which runs in tapered roller bearings. The rotors are separated from each other by diaphragms so that they can operate as three separate motors. On starting the vehicle the hydraulic fluid supplied by an engine driven pump flows into all three rotor chambers so that the motors run at low speed but produce maximum torque. As the vehicle speed increases one rotor is cut off from the fluid supply, increasing the shaft speed but reducing torque and for maximum speed only one motor receives fluid.

The cable may also be heated after filling to help attain the required viscosity.
Patent DE-2416222-A1 (DE)
Title: Magnetic tape recording using different coercivities simultaneously - allows different channels to be recorded on coincident tracks
Inventor: BROSOW JOERGEN ING
IPC: G11B5/03
Filed: 1974-04-03
Abstract: A technique of recording two sets of information, binary or analogue, on coincident tracks on magnetic tape, uses materials of two different coercivities, typically, iron oxide for low coercivity, and chromium dioxide for high coercivity may either be mixed and deposited on plastic tape, or may be deposited in separate layers of different thickness. The system may be used for analogue signals, for example to store an orchestra on one track and a soloist on the other. The main use, however, is for storing binary information on the high coercivity track and a masking, or concealing signal on the low track. In order to read the information on the former track, the low coercivity message must first be erased by a suitably driven head.
