Title: Oxygen recovery from air using nickel - dimethylglyoxime as absorbent
IPC: C01B13/02
Filed: 1969-09-18
Abstract: O2 (up to 98%) is recovered from gas mixture, esp. air, by reversible selective absorption in son. of Ni (II) dimethylglyoxime in 0.1-6, pref. 0.25-3.5 N KOH or NaOH, pref. at 1.1-3.0 atm. and 0.30 degrees C, followed by desorption by raising temp., pref. to 80-110 degrees C, and/or reducing pressure.

Filed: 1970-03-21
Abstract: Hydrogen produced industrially by the reaction of water and a C-contng. cpd esp a hydrocarbon, is used to yield deuterium-enriched hydrogen or water by isotopic exchange reactions. Hydrogen produced is contacted counter- currently with an intermediate medium (pref. of or contng H) to enrich the medium in deuterium; this medium is further contacted with water again counter-currently to effect interchange of deuterium.

Title: Open-end spinning brake - is operated on yarn breakage or other stoppage by common control system
Inventor: STAHLECKER FRITZ
IPC: D01H4/30
Filed: 1973-05-10
Abstract: The stop mechanism for the open-end spinning unit incorporates a brake unit common to all spinning units and individually controlled operating components which is coupled to the on/off switch system of the feed mechanism. The purpose is to compensate for the fact that the loosening roller has a higher rotary speed than the feed roller, allows reverse motion to pick up the new sliver on resumption of spinning, and also allows a visual inspection of the spinning zone when the housing is pivoted open, with links between the yarn sensor and the coupling to stop the unit on a yarn breakage.
Patent DE-2352404-A1 (DE)
Title: Gas centrifuge hysteresis motor with perforated disc rotor - has constant thickness at centre decreasing with distance from centre
Inventor: WINKLER HEINZ DIPL-ING
IPC: H02K19/08
Filed: 1973-10-18
Abstract: The hysteresis motor with perforated disc rotor for gas centrifuges etc. has the thickness of its perforated rotor disc decreasing in passing radially outwards from the rotor axis. This thickness is decreased with the distance from the axis. The inner part of the disc has a constant thickness which has a transition into the outer part with the decreasing thickness. The thickness of the inner part is chosen so that this part material has the greatest possible permeability at the motor rated speed. This shape of disc considerably reduces the motor higher harmonics and thereby avoids the losses associated with them.

Ready allowance is made for tolerances in the individual structural elements, and formwork pressure is effectively accommodated, and there is no danger of concrete escaping during site-concrete filling.
Patent DE-2352740-A1 (DE)
Title: Refuse compactor with control circuit - ensures refuse container actuates door switch and that container is locked in position during compacting
Inventor: HERMEIER WERNER
IPC: B30B9/30
Filed: 1973-10-20
Abstract: The compactor accommodates a detachable and removable container. The system has two door contacts for safety reasons and after the door switches have been actuated by the inserted refuse container and the main switch actuated, the press ram moves downwards and into the refuse container. During this process the switching lever is lowered and the locking plate is moved to ensure that the container does not move. This arrangement ensures that the container is not moved when the press pushes an empty tin or a rigid component in the refuse. After the completion of pressing the locking plate is moved away and the container can be readily moved out of the compacting machine chamber. The force required to remove the container is relatively low and it is less than that used when the container wheels are locked into the notches in the chamber floor.

Title: Electrographic copier document transport - carriage moves forwards and back below exposure window
Inventor: CRANSKENS GEORG
IPC: G03B27/50
Filed: 1973-11-02
Abstract: The forwards movement of the document transport carriage causes an exposure of the document image via means conducting the image rays onto a receiving surface in the interior of the copier, and moved in the same sense in synchronism with the carriage. During the return movement of the carriage, the means conducting the image rays are modified such that a negative of the document can be obtained, with the receiving surface continuing being displaced in the same direction, or using a second receiving surface. An optical system (8, 9) using two sets of mirrors or prisms behind an objective (66) can be displaced relative to the image beam. The first mirror or prism set (8) has its edges perpendicular to the image aperture.
