Title: Cowshed plastics sectioned grating floor - has interlocking hooks along edges of strips, preventing sideways compression
Inventor: SUDING ALFONS
IPC: E04F15/02
Filed: 1980-12-11
Abstract: Rows of sliding protective elevations are located between lengths of plastics, with bottom reinforcing profiles and parallel rows of lengthways slots, brought together to form a grating floor in a cattle shed. On the longitudinal edges (6,7) of each length there are connecting elements, in the form of notching devices, for bringing into effective locking contact with corresponding connecting elements on an adjacent length. Connecting elements can be angular strips (8,11) formed on in the peripheral area, aligned parallel to the edges. There is no danger of adjacent lengths of grating material being pressed together by penetrating dirt.

Title: Pebble bed reactor side reflector keyed to bottom reflector - has rotations resisting connections to side thermal shield
Inventor: KOLODZEY JUERGEN
IPC: G21C5/08
Filed: 1980-12-18
Abstract: A hollow cylindrical (annular) side reflector for nuclear reactors, esp. gas-cooled reactors with a core composed of loose spherical fuel elements (pebble bed reactor) has the bottom reflector penetrating up into it from below; the side and bottom reflectors are keyed together. The side reflector has radial struts transmitting radial forces to the thermal shield outside it and thus to the liner of the vessel. Between the side reflector (3) and thermal shield (2) and liner restraining devices (1) to prevent rotation of the side reflector are incorporated. Preferably, the anti-rotation device (1) consists of a radial bar bolted (10) to the thermal shield (2) and engaging in a groove (6) formed in the side reflector. The bar pref. has a head (5) inside this groove. Beneath the base of the bar (4) and the thermal shield (2) a seating plate or washer (11) and a wedge-shaped plate (12) are pref. provided. Used for a pebble bed reactor where the side reflector is keyed to the bottom reflector. Since the bottom reflector contains funnel-shaped outlets for discharging the fuel and since the fuel can be asymmetrically displaced by absorber rods penetrating into the core, asymmetrical forces acting on the bottom reflector can cause it to rotate. There is thus a tendency for the side reflector to execute an accompanying rotation. The objective of the restraints is to prevent this rotation.

Patent DE-3125121-A1 (DE)
Title: Hydrostatic appliance
Inventor: MEYERLE MICHAEL ING GRAD
IPC: F04B1/22
Filed: 1981-06-26
Abstract: The invention relates to a hydrostatic appliance whose manufacturing costs can be reduced by employing a small-volume discharge port body. The small dimensions of the discharge port body permit an advantageous embodiment of the hydrostatic casing, whose end casing section or centre casing section projects into the domain of the axial-piston machine in question. Thus assembly of the latter can be carried out more simply and safely. Moreover, by virtue of the small dimensions of the discharge port body, a considerable reduction in noise can be achieved, and it is possible to accommodate a piston for adjusting an optional pivoted plate, without requiring additional overall volume.
Patent DE-3125536-A1 (DE)
Title: Method for pulse-code modulated transmission of radio and television signals
Inventor: DIRR JOSEF ING GRAD
IPC: H04J7/02
Filed: 1981-06-29
Abstract: The digital transmission of sound, data and images, including those for television, via radio requires many times the bandwidth required in analog transmission. For a digital television image, for example, a signal flow of 140 Mbit/s is required. Due to this enormous bandwidth requirement, digital transmission by radio has not been successful in spite of the use of quadrature amplitude modulation. In the invention, the great bandwidth requirement is avoided by providing for the digital coding of the signals a binary code which is formed from the half-waves for periods of a sinusoidal alternating current having the characteristic states of large and small amplitude values and is transmitted in an uninterrupted sequence of positive and negative half-waves. In this arrangement, a multiple utilisation of the respective transmitter is provided by time-division multiplexed and/or frequency-division multiplexed arrangement of the alternating coding currents of the various channels and modulation onto the alternating transmitting current and/or by providing the alternating transmitting current directly as alternating code current.

Title: Internal combustion engine, especially for motor vehicles, with the exhaust gas pressure used to improve the cylinder charging
Inventor: WILLMANN MICHAEL ING GRAD
IPC: F02B29/06
Filed: 1981-09-21
Abstract: For ram pressure charging without energy transfer by way of rotating parts the inlet and exhaust valves (E1, E2; A1, A2) on a pair of cylinders of an internal combustion engine can be connected crosswise by way of connecting lines (4, 5) in a control slide valve (3) which rotates at the speed of the engine camshaft. The course of the connecting lines (4, 5) in relation to fixed lines and ports (6, 7, 12, 13, 14, 15) is selected so that only at the start of the opening of the respective exhaust valve (A1, A2), that is during the pre-exhaust shock, is a connection created to the inlet valve (E1, E2) of the other cylinder and boosting thereby brought about. In the rotary slide valve (3) direct fresh gas inlet ports (10, 11) and direct exhaust gas ports (8, 9) are also provided which, when connecting lines (4, 5) are separated from the exhaust valves (A1, A2) but connected to intake lines (14, 15) for fresh gas, temporarily ensure scavenging of the respective connecting line (4, 5) in a manner similar to a jet pump. <IMAGE>

Title: Circuit arrangement for extending the range of linearity of a controllable resistance
Inventor: PARRAS KARL-HEINZ DIPL ING
IPC: H03H11/46
Filed: 1981-12-23
Abstract: In this circuit arrangement, the voltage which is present across the input terminals of the arrangement is first supplied to a differential amplifier, the input impedance of which is extremely high and the gain of which is less than 1. The output voltage of the differential amplifier is one of the input variables to a control circuit which contains the controllable resistance between two further terminals. It controls two controllable current sources or voltage sources in such a manner that when a voltage is applied to the input terminals of the arrangement, a current flows which is proportional to the applied voltage and inversely proportional to the resistance value of the controllable resistance. The components required for the internal construction of the control circuit and the current sources or voltage sources can be dimensioned in such a manner that the input impedance of the arrangement corresponds to the resistance value of the controllable resistance.

Patent DE-3210109-A1 (DE)
Inventor: OTTERSBACH WALTER
IPC: B23D25/12
Filed: 1982-03-19
Abstract: Beim Längsteilen und Besäumen von Metallbändern in einer Kreismesserschere fallen Saumstreifen an, die in einer nachgeschalteten Saumschrottschere zerkleinert werden können. Eine Saumschrottschere besteht üblicherweise aus zwei sich gegenüberliegend angeordneten Scherenständern (2), die jeweils zwei Messerwellen (5, 8) für Messerköpfe (13, 14) aufweisen. Die gegenläufig rotierenden Messerköpfe (13, 14) sind mit schräg eingesetzten Messern (11, 12) bestückt, so daß der Saumstreifen beim Eintritt in den Messespalt zerstückelt wird. Die Saumschrottschere ist für einen eingeschränkten Schnittbereich ausgelegt. Innerhalb dieses Schnittbereiches erfolgt eine gezielte Messerspalteinstellung. Trotzdem platten die Messerschneidkanten sehr schnell ab, insbesondere wenn dickere Materialien geschnitten werden. Das führt dazu, daß beim Übergang auf geringere Dicken diese dann nicht mehr vollständig durchtrennt werden. Ein häufiger Messerkopfwechsel ist die Folge, der reduziert werden kann, wenn einer der beiden Messerköpfe (13, 14) eines jeden Scherenständers (2) radial mittig geteilt wird und die Messerkopfhälften (14a, 14b) mit Abstand zueinander auf der Messerwelle (5) befestigt werden.

Title: Metal parts and method of producing them
Inventor: SCHMIDT LOTHAR DR ING
IPC: B65H57/24
Filed: 1982-03-29
Abstract: The invention relates to metal parts, in particular thread-guiding parts in textile machines. Apart from the actual metal thread guides, these comprise, in particular, needles on knitting machines. The invention also relates to a method of producing the metal parts, which method can also be used to treat tools and tool parts. The object of the invention is to provide metal parts by means of a continuous and economical method. Said metal parts are hard and wear-resistant while having a particularly smooth surface, and they do not acquire cracks and notches even on prolonged use. According to the invention, the surface of the base material of the metal parts underneath an electroplated coating is at least equally as hard as the coating but has about the same coefficient of thermal expansion as the base material. The method of producing them is to prefabricate the parts until the final base material shape is obtained and to chemically alter them by diffusing in an element of main group 3 of the periodic system of elements from a gas phase. This treatment is followed by a polishing operation, which is preferably electrochemical and the parts are then provided with a thin electroplated coating.
