Patent DE-2748084-A1 (DE)
Title: Water clarification system for intensive fish farming - centrifuges effluent to which oxygen and hydrated lime are added
Inventor: TEBBENHOFF EBERHARD DR
IPC: A01K63/04
Filed: 1977-10-27
Abstract: Stale water continuously drawn off from a pond on a farm for intensive fish prodn., and replaced by clarified, esp. aerated water, is centrifuged to separate it into a concentrated sludge and clarified water. This with the addn. of a quantity of fresh water is then returned to the pond. System maintains the water in fish ponds for intensive prodn. in a condition in which the fish thrive and are free from disease, without a clarifying process which is disproportionately high in cost and requiring the input of energy to maintain the temp. of the pond uniform in summer and winter. Solid matter is removed at a rate which is higher than that at which bacteria and fungus can multiply. The sludge produced can be composted and used as fertiliser. The concentration of salts and dissolved organic matter can also be maintained at a level to keep the fish healthy. Oxygen in the form of fine bubbles in injected into the stale water as it is drawn from the tank, and before centrifuging also, hydrated lime is added. This precipitates calcium carbonate which envelopes particles of albumen etc. The ratio of clarified to fresh water returned to the tank is only as 8:1.

Title: Heating or drying yarns - by passing the yarns through a chamber, altering the direction of path and blowing hot medium across the path
Inventor: KREMLEV OLEG ALEKSANDROVITSCH
IPC: D02J13/00
Filed: 1977-11-02
Abstract: Appts. used includes a heat treatment chamber in which is arranged a pair of vertically spaced rollers, the axis of one roller being inclined towards the axis of the other roller and in the direction of axial movement of the yarn which is wound several times about the rollers. During passage over the rollers the yarns are subjected to a blast of hot air from nozzles associated with a duct, the nozzles which are spaced vertically are provided in tubes. Alternatively, the nozzles may be formed by vertically extending partition walls of metal and the spacing between adjacent walls forms slots which extend in the plane of the windings of the yarn. Heat transfer is improved without increasing the size of treatment chamber.

Title: Adjustable aerated concrete cladding panel fixture bar - has guideways in anchor head shaft opening permitting movement lengthways
IPC: E04B2/94
Filed: 1977-12-03
Abstract: The fitting is for attachment of aerated concrete cladding slabs, to a support structure of concrete, steel, wood, etc. It comprises a flat rail-type bar for nailing or otherwise fixing to the slab top, with a hammerhead jutting out from a shaft.

Title: Adjusting metering and mixing pigments for paint, etc. - by hose pump and revolution counter dispensing using valves
Inventor: BARRY JUN JOCHEN
IPC: C09D7/80
Filed: 1978-02-22
Abstract: A tube pump fitted with a revolution counter forms the feeding and metering arrangement in a plant for adjusting, metering and mixing, esp. pigments for the mfr. of lacquers, paints and similar products. The plant has a number of colour containers to each of which a feeding and metering arrangement is allocated. The tube pump consists of a rotatry disk with, or its end face, squeezing cams. These pumps compress a hose which is laid out in a section of housing following a line corresponding to a circle enclosing the squeezing cams and the path which they follow. The plant constitutes an improved means of mixing lacquer and dispersion pigments, mechanically, so that cleaning operations on changeover are much easier, valves being dispensed with. The only component suffering wear is the cheap hose of the pump.

Title: Electronic wrist watch incorporating pulse rate monitor - has pressure sensor at back of watch or watch bracelet directly contacting wrist
Inventor: BOCK EDDO ING GRAD
IPC: G04B47/06
Filed: 1978-10-23
Abstract: The digital watch provides a warning signal when the wearer's pulse rate is excessive, to prevent over-exertion, e.g. when convalescing from an illness or during sports training. The pulse rate monitor uses a pressure sensor positioned at the back of the watch case, so that it is in contact with the wearer's wrist. The pressure sensor may be piezoelectrical or electromechanical. The limit value for the pulse rate may be selected according to a variable programme, with an acoustic, optical or mechanical warning signal provided when it is exceeded. Alternatively, the pressure sensor for the pulse monitor may be attached to the rear of the watch bracelet, in such a position that it is in direct contact with the wrist artery. The incorporation of the pulse rate monitoring with the watch allows a continual unobtrusive monitoring of the pulse rate throughout the day.

Title: Nuclear fusion system - by magnetic confinement, compression and resistive heating of plasma ring
Inventor: WIDMANN DIETER
IPC: H05H1/02
Filed: 1979-02-23
Abstract: Parent Patent No. 2827389 described an atomic nuclear fusion based on the magnetic enclosure and magnetic compression of a plasma. A d.c. supply is used to charge the large inductance of the exciter coil with a linearly rising geed current. This confines the plasma by its magnetic field. On reaching a set max. this current is disconnected and the stored energy must be absorbed by the plasma ring, producing a nuclear fusion by compression and resistive heating. System combines an energy storage and plasma enclosure with a compression by a discharge with a high peak output. The process can be repeated cyclically.
