Title: Food container for free-flowing foodstuffs for feeding small animals
Inventor: KIEPER JOACHIM
IPC: A01K5/01
Filed: 1981-02-21
Abstract: In institutes for experimental animal research the laboratory animals are also offered their food in portions. It should be possible for the individual animal, preferably a rat or a mouse, to eat the portion presented in an unsoiled state. In order to correspond with this fundamental requirement the food container must have the following properties: - the portion comprising a few grains or pellets falls in free fall and in tubes towards the food container. The energy from free fall must be smashed; isolated grains must not be sprayed through the eating hole into the animal cage; the laboratory animal must not be able to crawl through the eating hole into the food container and it must not be able to sleep therein. Furthermore, the laboratory animal must not be able to soil the food in the container with faeces, urine or bedding. These requirements are met by the technical design of the food container. The food container can be filled with very small portions and a multiple thereof (1 g - 30 g). This container permits controlled consumption of food. <IMAGE>

Title: Method for manufacturing metal hurdles
Inventor: HEIL WERNER
IPC: B65D19/28
Filed: 1981-12-02
Abstract: Method for manufacturing metal hurdles comprising a supporting frame to which a covering sheet-metal plate with a plane supporting surface is fastened. First of all, the supporting frame of steel sections is welded together and fastening holes are drilled into the sections at right angles to the supporting surface in a predetermined hole pattern. The supporting frame is then hot-galvanized. Subsequently, the supporting frame is aligned in such a way that any deformations of the supporting frame due to the thermal stresses of the welding process or of the hot-galvanizing are rectified, so that the bearing surfaces, facing the sheet-metal plate to be fastened, of the sections are aligned in one plane. The sheet-metal plate to be fastened to the supporting frame and manufactured from corrosion-resistant or hot-galvanized perforated sheet metal is likewise aligned so as to be precisely plane. Threaded bolts protruding at right angles are then butt-welded at one end to the surface of the sheet-metal plate to be fastened to the supporting frame in an electrical resistance-welding process, in accordance with the hole pattern of the fastening holes in the supporting frame. The sheet-metal plate is then placed onto the supporting frame so that the threaded bolts pass through the fastening holes. By screwing nuts onto the free threaded-bolt ends, the sheet-metal plate is fastened to the supporting frame in a stress-free manner.

Title: Circuit arrangement for evaluating a test signal output by a device under test, for example a circuit board
Inventor: BILUSIC TOMISLAV
IPC: G01R31/3193
Filed: 1982-08-13
Abstract: When testing a device under test, for example a circuit board, the test signals output by the device under test on the basis of input signals are compared with nominal values in the circuit arrangement and an error signal (FS) is generated in the event of inequality. For this purpose, the number of level changes of the test signal (TS) is determined in a measuring time window and at the end of the measuring time window the state of the level of the test signal is determined. The test signal (TS) is supplied to at least two comparators (10, 12) which generate a comparator signal (LX, HN) when the test signal exceeds the associated reference voltages (ULX, UHN). The comparator signals (LX, HN) are supplied to an alternation counter (48) which is incremented in each case by one step when the test signal (TS) either exceeds or drops below the two reference voltages (ULX, UHN) (level change). The content of the alternation counter (48) is compared with a nominal value and in the case of a difference, the error signal (FW) is generated. The comparator signals (LX, HN) are also used for determining whether the level of the test signal (TS) at the end of the measuring time window corresponds to the nominal value (S16). In the case of non-correspondence, an error signal (FZ) is generated. The reference voltages for the comparators (10, 12) are obtained from digitally coded values and can thus be easily changed. <IMAGE>

Title: Electrical connection between the panels of a solar generator for satellites
Inventor: KIENDL HELMUT
IPC: H01L31/04
Filed: 1982-10-30
Abstract: In order to construct an electrical connection between the panels (which can be folded and unfolded) of a solar generator for satellites, it is proposed, in order to prevent thermal and mechanical stresses as far as possible, to use electrical connections 3 which are wound on spirally between their two ends. In particular, it is intended that the two ends of the electrical connection 3 by means of which said connection is mounted on the panels 1, 2 point away from one another by approximately 90 DEG  before installation. In consequence, a torque is produced during unfolding which initially assists the unfolding and then constrains the unfolding and hence reduces the latching-in shock. The electrical connection 3 may be a wire mesh or an elastic wire clip. <IMAGE>

Title: Radial piston pump
Inventor: BUDECKER LUDWIG
IPC: F04B1/113
Filed: 1982-11-02
Abstract: The invention is based on a radial piston pump for the delivery of free-flowing media, in which two or more spherical piston elements (6, 7) are mounted in a self-contained, cross-sectionally circular circumferential groove (3) of a drive shaft (1) guided rotatably in a cylinder body (4) and can be made to perform reciprocating movements. The piston elements (6, 7), the housing (2) and the circumferential groove (3) form spaces (13, 14), the volumes of which are dependent on the position of the drive shaft (1). The spaces (13, 14) of varying volume have connections (17, 18) to the suction side (5) of the pump, so that during operation of the pump there builds up in the suction chamber (5) a small preliminary pressure, which supports the suction movement of the piston elements (6, 7, 9, 10). <IMAGE>

Title: Apparatus for disintegrating waste wood, in particular stumps, to form wood chips
Inventor: QUELLE HERMANN
IPC: B02C18/14
Filed: 1982-12-08
Abstract: An apparatus for disintegrating waste wood, in particular stumps, to form wood chips consists of a rotor which is arranged inside a shaft, has a substantially horizontally supported rotor spindle and carries, on its outer periphery, a multiplicity of cutters which co-operate with counter-cutters fixed in relation to the shaft. To improve the operational reliability of the apparatus and as far as possible avoid breakdowns due to accumulated disintegration material, the rotor cutters are mounted freely rotatably in the region of the rotor outer circumference about pivots arranged parallel to the rotor spindle. In this case, the rotor cutters are moved, upon rotation of the rotor, by centrifugal force into their working position projecting radially beyond the rotor outer circumference and are moved, upon striking an obstacle, against the centrifugal force into a deflected position lying substantially inside the rotor outer circumference. Furthermore, material accumulations in the feed and discharge region of the rotor can be counteracted by a pivotable holding-down device in the region of the counter-cutters and a rotor-shaft base which is of open design at least in certain regions.
