Title: Enclosure for electronic equipment generating heat losses - contains cooling ducts acting as heat exchanger and filled with evaporable medium
Inventor: MATSUI FUMIO
IPC: F28D15/02
Filed: 1979-11-21
Abstract: The application is to electronic equipment employing power circuits which produce heat losses and therefore require cooling. The housing (1) comprises a lid with a vertical section (3) and a horizontal section (2). Embedded in these sections are continuous, closed heat pipes (4) forming a spaced out cooling system. The main heat generating elements (6), for example power transistors, are mounted on a strip (5) at the base of the vertical section (3). The heat pipes are filled with a liquid which vaporises by the heat from the circuit elements (6) and condenses again in the horizontal part of the cover. In this way the thermal losses are dissipated in a system acting as a heat exchanger. The space requirements are less than for a direct air cooled system employing convection.

Title: Liq. manure agitator impeller - has air outlet openings and guide vanes above impeller vanes to prevent clogging of air outlets
Inventor: GROTZ WILHELM
IPC: A01C3/02
Filed: 1980-04-30
Abstract: An agitator for liq. manure and similar liqs. consists of an impeller on a vertical tube which is driven by a gear motor and adjustable in depth. The hollow vertical tube is used as an air inlet and has air outlet openings above the level of the impeller. A blank flange closes the tube just above the impeller. An air guide vane array can be arranged at the level of the air outlet openings. The hollow drive tube is open at the top and bottom and is joined on its ring by spacers to a separate piece of tubing. This leaves air outlet openings between the spacers. The tubing is closed by a blank flange and carries the agitator impeller. An air guide vane array can be suspended on chains when not in use. It carries curved vanes to guide the air from the openings into the manure and is coupled by several keys to L-shaped keyways when in use. This prevents any clogging of the air outlet openings, specially during the starting period. The new system results in a uniform air input in the manure at a high efficiency.

Title: Apparatus for the metered release of bulk material onto a conveyor belt
Inventor: SCHWOLLE FRANZ DIPL ING
IPC: B65G47/20
Filed: 1981-04-25
Abstract: The invention is concerned with an apparatus for the metered release of bulk material (1), such as rocks, onto a conveyor belt (2), especially for roadway drivage in underground mining. Arranged above the conveyor belt (2) is a charging trough (3), oriented in the direction of the belt, with a trough bottom (4) and trough frame (5), as interim storage. The trough frame (5) can be moved in the direction of the belt with the trough bottom (4) stationary, as a result of which the bulk material (1) located in the charging trough (3) is satisfactorily released with uniform distribution onto the conveyor belt (6) situated below it. The use of a release apparatus makes the satisfactory charging of the belt conveyor (2) possible and enables such a belt conveyor (2) to be used instead of a chain conveyor, which is otherwise conventional. With the aid of the conveyor belt (2), which is easy to guide, the machine burden can be completely smoothed in the drivage. <IMAGE>

Title: Differential pressure measurement apparatus with measurement position changeover capability
Inventor: SCHMIDT RUDOLF
IPC: G01L19/08
Filed: 1981-05-20
Abstract: The proposed differential pressure measurement apparatus, with a measurement position changeover capability, is used for measuring differential pressures with very high precision over a measurement range of several powers of ten. A differential pressure measurement converter chain (3) is used for this purpose, consisting of several differential pressure measurement converters for different measurement ranges, from which a control electronics device selects the measurement converter which is most accurate for the applied differential pressure, and automatically connects it via solenoid valves. When this differential pressure measurement converter chain is being used, the differential pressure measurement converter (61) with the lowest measurement range is initially subjected to the applied pressure difference and its measured value is forwarded to the evaluation electronics device. If a specific predeterminable threshold is exceeded, the next higher differential pressure measurement converter is connected, while the first is vented to prevent damage from excess pressure. The changeover lasts until the differential pressure measurement converter with the suitable measurement range is connected. This differential pressure measurement converter chain (3) is particularly suitable in conjunction with a measurement position changeover system (2) which permits the optional connection of various measurement points to the differential pressure measurement converter chain. <IMAGE>
