Patent DE-2904911-A1 (DE)
Title: Intensive fish farming system - has water circulating through coarse and fine cleaning stages followed by sterilising process
Inventor: KAHL BORIS
IPC: A01K63/04
Filed: 1979-02-09
Abstract: The procedure is for treating the circulation water in intensive fish farming systems. The dirty water from one or more tanks is first subjected to a mechanical coarse cleaning, after which there is a fine cleaning. Finally, before the water is returned to the tanks, it is sterilised by a process of irradiation with suitable radiation. This latter procedure can also take place during the fine cleaning. More specifically, the temp. of the circulating water is controlled according to the type of fish.

Title: Vertical clamp arms on lifting head - are used to reduce height of stack of stone blocks
Inventor: DIRKES RALF
IPC: B65G59/06
Filed: 1979-08-18
Abstract: Stacked stone blocks (3), or modular blocks such as bricks, are lifted by a transfer clamp head (2) to an unstacking table (1). The clamp head (2) has two parallel vertical arms (4,5) for gripping opposite sides of the stack (3). In order to remove the lowest layer from the stack, the clamps (4,5) move to the layer above and lift the remaining stack clear. A pusher cylinder (9) then moves the layer of blocks on the table sideways so that the process can be repeated.
Patent DE-2935136-A1 (DE)
Title: Positional correction drive circuit - is for self-aligning microwave antenna, and compensates for in-the-wave transfer guides induced secondary error signals
Inventor: GIEFING ANTON DIPL ING
IPC: H01Q25/04
Filed: 1979-08-30
Abstract: The circuit is capable of eliminating the effect of internally generated non-relevant wave-modes. A collector cone (6) provides the transition to a hollow conduit feed line (8) which couples to the mode coupling circuit (9) which splits the H-21 wave into phase components (13a,13b). A 90 degrees - 3dB hybrid amplifies the signals and feeds them into a switch (21) which permits either the left or the right circular polarised wave to be passed to the compensation amplifier (36) from which is derived the differential error correction voltage (38). However, on the component lines (13a,13b) are also present interference signals (Sa,SB), and these must be made ineffective. This is done by means of the polarisation gate (10) which separates the fundamental applied to unit (22) which receivees the useful signal, and the aforementioned both wanted and unwanted higher order wave signals which are passed to an amplifier (26) and the two outputs to quad phase shift/attenuator members (29,30) and further phase correction members (31,32). After eliminating the left or right circular component in a termination resistance (34) the remaining signal is applied to the compensator unit (36) where the unwanted components cancel each other.

Title: Thimble for attaching clothes-line to hook - has flattened pear-shape with peg fastening for line at apex
Inventor: SCHOENEBERGER JOSEF
IPC: D06F53/04
Filed: 1979-11-03
Abstract: A device for attaching washing lines of fine, natural or synthetic cords with a plastic covering to hooks, etc., comprises an open-sided, pear-shaped thimble having a curved groove on one side to accept the hook, and a large-radius, transversely-curved surface on the other side over which an eye in the end of the line can be dropped. The device has a pair of wings extending along the fixed line a short distance, one on either side, with a hole across the outer ends into which a peg can be placed, over the top of the line, to prevent the loop from jumping off the thimble. The device reduces the stress in the line, and prevents abrasion on the small-radius, metal hook, increasing the useful life of the line.
Patent DE-2948005-A1 (DE)
Title: Adjustable ergometer seat support holder - has two plate guides, each with opening matching seat support cross=section, held in mutual alignment
Inventor: MAYER WERNER
IPC: A47C3/28
Filed: 1979-11-29
Abstract: The two guide plates (9,11;14,15) have through apertures (10,13) matched in shape and size to the cross-sectional shape of the rod-like seat support (5). They are held by a holder (6,17) in a position where the apertures are mutually aligned. A spreading mechanism (12) is provided to adjust the angle of the two guide plates at least in the area with the apertures. The play of the seat support in this holder is thus not determined by the manufacturing tolerances of the apertures, but by the spreading angle of these guide plates.

Title: Testing method for semiconductor arrangements at different temp. - involves localised heating and cooling of test object
Inventor: BECKENBACH WALTER
IPC: G01R31/26
Filed: 1980-10-02
Abstract: The test method is for semiconductor arrangements using a test circuit and involves a very short electrical connection between the test circuit and the tested circuit. It enables the tested circuit to be examined at different test temp. very accurately and in a relatively short time. The different test temp. are not produced in a temp. chamber but by local heating and cooling of the object. It is ensured that only the object is heated and cooled whilst the test circuit remains unaffected. The localised heating and cooling takes place as rapidly as possible using an attached heating body or thermal radiation and cooling gas or liquid. The heating or cooling medium is at a higher or lower temp. respectively than that to which the object is to be brought.

Title: Method and arrangement for the defrosting of ice on an air cooler of a heat pump or refrigerator
Inventor: BIRR RAINER DIPL ING
IPC: F25D21/00
Filed: 1981-03-16
Abstract: In a method for defrosting the ice precipitating from the air on the surface of an air cooler of a heat pump or of a refrigerator, a defrosting cycle is initiated automatically at particular time intervals, and during the course of this the air cooler is subjected to a quantity of heat sufficient for melting the precipitated quantity of ice. The time sequence of the defrosting cycles is controlled by a microprocessor in accordance with values for the quantity of ice precipitating on the air cooler of the heat pump or refrigerator, these values being calculated from the Mollier h-x diagram for moist air. In the case of fixed rating parameters of a heat-pump or refrigerator system, the microprocessor can be programmed in such a way that the control of the defrosting cycles can be carried out solely as a result of a measurement of the temperature and relative air humidity of the air entering at the air cooler.

Patent DE-3144734-A1 (DE)
Title: Diaphragm pump
Inventor: STAHLKOPF FRIEDRICH
IPC: F04B43/00
Filed: 1981-11-11
Abstract: The invention relates to a diaphragm pump in which the primary working medium is admitted to a tubular hose diaphragm composed of elastomer material and in which the secondary medium is located in a pump chamber surrounding the diaphragm. The invention ensures that in the case of diaphragm pumps of the generic type the maximum possible piston displacements and/or delivery flows and delivery pressures can be achieved for the lowest possible weight and/or the smallest possible overall dimensions. This is achieved in that the pump chamber is defined by a spherical housing and the outer circumferential surface of the hose diaphragm, which is clamped in the housing by its two ends. In addition a method applicable to the above-mentioned diaphragm pump ensures that in the event of a defect in the diaphragm the primary working medium is not contaminated by the secondary medium to be pumped, which as a rule is viscous and abrasive or laden with solids. This is achieved, inter alia, by the fact that in each phase of the induction stroke of the diaphragm pump the timing of the volume reduction of the working medium inside the hose diaphragm is varied in such a way that this reduction in the volume can be completed without any delay due to recovery of the elastically extended hose diaphragm exerting pressure on the working medium. <IMAGE>
