Title: Testing substances for harmful effects - by determining plasma polypus formation
Inventor: THORN WERNER PROF DR
IPC: A61K49/00
Filed: 1978-03-10
Abstract: A method for testing chemical and biological substances (pharmaceuticals, foodstuffs, pesticides, solvents, etc.) for harmful effects and for eliminating such effects is claimed. The test method comprises applying the substance to a test animal, allowing the substance to act for a sufficient time, and determining the no. of protrusions with a low cell-organ content (plasma polypi) in the blood plasma of the animal by reverse centrifugation and counting or by comparative counting of the plasma polypi in histological sections from the tissue of the animal. If the test result is positive, the substance is opt. combined with a cpd. (I) which reduced plasma polypus formation. The method is based on the findings that (a) certain substances (e.g. monoiodoacetate and Na acetylsalicylate) increase plasma polypus formation, esp. in pregnant females; (b) there is a correlation between plasma polypus formation and pathogenesis during gestation; and (c) cpds. (I) counteract the pathogenic effects of the substances.

Title: Clamp for holding together two plastics parts - is of spring steel and parts are of different cross section
Inventor: GRAUMANN PAUL
IPC: F16B2/24
Filed: 1978-04-28
Abstract: The clamp is used for fixing two plastics parts of different cross-section to each other, and is bent out of spring steel strip. The bent shape conforms with that of the two parts to be joined. The spring force of the clamp (A) is such that the two plastics parts (B, R) are held together so that no torsional or tipping movement between them is possible. Nevertheless, the parts can expand under the effect of heat, causing them to draw apart and together again, but this in no way detracts from the ability of the clamp to prevent them twisting or tipping.

The rods (3, 3') are offset on each side of the centre-line (2) of the body (1), which is not circular in section. Both rods can thus travel the full length of the unit, thus doubling its effecting stroke. Stops (14, 14') are fitted to the ends of the rods, to prevent them from being pulled out through the plugs.
Patent DE-2914296-A1 (DE)
Title: Phase controlled triggering of thyristor - using optical link between control element and trigger circuit obviating isolating transformer
Inventor: LOB UDO DIPL ING
IPC: H02M1/08
Filed: 1979-04-09
Abstract: A thyristor (1) controls a load (17) connected to a single phase a.c. supply to give galvanic separation between the control element and the mains. This is achieved by employing an opto-coupler (7) dispensing with an isolating transformer. A capacitor circuit (2, 3, 4) across the mains is charged during the blocking half cycle across the thyristor (1). As the voltage reduces towards the end of the half cycle the capacitor (3) discharges via a limiting resistor and diode (15, 16) into a second capacitor (6). The charge voltage may be limited by a Zener diode (4). An optically controlled circuit (5) applies the stored charge of the second capacitor (6) to the gate of the thyristor in response to a light signal from the control element. The latter can be synchronised with the mains.

Title: Concrete pressure vessel, esp. for nuclear reactor - permits formation of microscopic fissures to redistribute stress
Inventor: SCHOENING JOSEF DIPL ING
IPC: G21C13/00
Filed: 1979-05-03
Abstract: The cylindrical concrete pressure vessel, has tensioned reinforcements. It has caverns and passages with metal liners, for various operational pressures. The concrete structure is arranged not for maximum operational pressure, but for actual pressure in the caverns or passages or a combined pressure. The structure is integrally pre-stressed, so that the internal pressure loads are not overstressed in all cross sections. The formation of microscopic fissures is permitted in localised areas, to demolish stress or stress peaks during stress rearrangements. Remaining local tensile forces are accommodated by tension cables; the metal liners, and their anchorings and the reinforcements.
Patent DE-2922341-A1 (DE)
Inventor: KAMPF KURT
IPC: B21C47/00
Filed: 1979-06-01
Abstract: It sometimes happens that an aluminium foil strip wound onto a steel core does not meet quality requirements. The steel core must then be recovered. The method solves this problem by heating the steel core together with the coil to 220 DEG -250 DEG C. Due to the difference in the coefficients of the thermal expansion, the steel core can then be pulled out of the coil. For this purpose, the whole is placed on a table with a vertical supporting plate having an opening, e.g. a slot, through which the steel core protrudes, and the steel core is pulled out with a pulling device.
Patent DE-2922866-A1 (DE)
Title: Thin layer chromatography using fluorimetric analysis - where sepg. agents are located on mirrors to increase sensitivity of fluorescence measurements
Inventor: ECKERT THEODOR PROF DR
IPC: G01N30/92
Filed: 1979-06-06
Abstract: The constituents of a mixt. are collected on thin film substrates coated with different sepg. agents. The sensitivity of the fluorimetric determn. of the sepd. constituents is increased by using a substrate coated with a reflecting layer, e.g. a glass mirror, or substances such as Al formed by vapour deposition and covered with a layer of silica. The fluorimetric technique measures the intensity of the back-scattered fluorescence. By using e.g. a glass mirror coated with a sepg. agent, fluorescence picked up by the mirror is reflected towards the measuring appts. Light reaching the mirror is reflected back through the fluorescent layer so the fluorescence is amplified and the sensitivity of measurements is increased.
Patent DE-2924359-A1 (DE)
Title: Automatic decoupler for trailer and tractor - uses electromotor to raise coupling bolt on receipt of command signal from cab
Inventor: ASSFALG ALOIS
IPC: B60D1/02
Filed: 1979-06-16
Abstract: The decoupler has an electromotor (2) raising the coupling bolt (15) via a screw or cam (19). The raised bolt is locked in its raised position and the tractor can be driven clear of the now decoupled trailer. The bolt can also be released electro-magnetically. It then drops down under gravity through the coupling eyelet of the trailer's tow bar- if the tow bar has been inserted into the tractor's towing device. The bolt may also be raised by a solenoid arrangement. The advantage is that the driver does not need to leave his cab to disconnect the trailer.

Title: Heat insulating composite member prodn. - inserts tube containing deformation strips in space formed between two rails, coupled by insulating strips
Inventor: NAHR HELMAR DR DR
IPC: E06B3/273
Filed: 1980-01-25
Abstract: The process is used for production of a heat-insulating profiled body, comprising two rails joined by insulating straps (3). The latter fit in undercut grooves (5) in the rails (1) and are pressed home by supporting ribs (6) on the rails. The rails and straps are first loosely assembled, after which two deformation straps (7,8) are inserted in the space (10) enclosed by them and forced apart by an expanding tool (11) against the ribs, bending these against the insulating straps. The deformation straps are inserted inside a tube (14), or a channel section, which is then inserted in the space (10) enclosed by rails and insulating straps. The tube, or channel section, is then extracted, leaving the deformation strips in place. Then the expanding tool is inserted between the latter and forces them apart.

Title: Variable speed positive feed for circular knitting machine - having multiple drive pulleys with selectively operable clutches
Inventor: GRIMM RAINER
IPC: D04B15/48
Filed: 1980-02-26
Abstract: A positive yarn-feed device for a circular knitting machine comprises a toothed delivery roller around which passes a toothed feed-belt. The belt passes around at least two independent drive pulleys, loosely mounted on separate shafts which are rotating at different speeds. The drive pulleys can be coupled to their shafts via pneumatically-operated friction clutches, which can be selectively operated by a patterning mechanism, whereby the belt speed can be altered during the knitting cycle to vary the yarn delivery-speed. The shafts are driven from a single power source by a common belt which passes around variable-diameter pulleys affixed to the shafts. The device is relatively uncomplicated and inexpensive, and enables the production of high-quality, forming fitting garments, esp. female underwear, by allowing variation of the yarn delivery-speed during the knitting cycle.

Title: Evaporator automatic defrosting device - is actuated when ice formation is detected by thrust rod actuated periodically by magnetic coil
Inventor: LINKE WOLFGANG
IPC: F25D21/02
Filed: 1980-02-28
Abstract: The automatic defrosting device for an evaporator incorporated in a humidifier, a refrigeration circuit or a heat pump, has a sensor element actuated at timed intervals to detect any ice formation at the evaporator surface. The sensor element comprises a thrust rod (1) which acts as the core of a magnetic coil (2). The latter is energised via a periodic switch (5) controlled by a pulse generator (4), causing the thrust rod (1) to be moved by several millimetres relative to the surface of the evaporator. If the movement of the thrust rod (1) is impeded by surface ice a control signal for actuating the defrosting unit is provided. The sensor element may alternatively comprise a periodically rotated disc spaced slightly from the surface of the evaporator, so that its rotation is prevented by an ice layer.
Patent DE-3009260-A1 (DE)
Title: Measuring values corresp. to blood separation - uses sudden or gradual transfer to low residual shearing
Inventor: SCHMID-SCHOENBEIN HOLGER PROF
IPC: G01N15/05
Filed: 1980-03-11
Abstract: The method for determining a measurement value corresp. to a blood separation involves using a syllectogram obtained from a blood sample. The blood aggregation is not measured at a sudden rest condition following shearing but after a transfer to a continuous low residual shearing. The transfer may be achieved suddenly or steadily. The beginning of the aggregation phase is selected as an extreme value of the syllectogram within a defined period following the transfer to constant residual shearing. Alternatively, the measurement may be made alternately for a sudden halt following shearing and after a transfer to a residual shearing. The method may be used for agglutination investigations.
