Abstract: The invention relates to a method and to a circuit configuration for adjusting the voltage level for the electrical data transmission between a transmitting component and a receiving component of one or different assemblies. According to the invention, the voltage level is increased step-wise or continuously until the required value for the correct representation of the signals to be transmitted is reached in the receiving component. Increase of the voltage level is stopped by the transmission of respective information. The inventive method and circuit are advantageous in that the minimum voltage level required for the transmission of data can be precisely adjusted. Power loss can be thereby reduced and adjacent channel interferences through high voltage levels can be reduced to a minimum.

Abstract: A method and a device for sintering ceramic shaped articles in a furnace which saves costs and energy but provides high throughput. To this end, the shaped articles are guided vertically through the furnace on the helical rib of a stationary, vertically positioned helix by the inner longitudinal ribs of a rotating, vertically standing tube which concentrically surrounds the helix.

Abstract: A rotary crane having a telescopic mast with a liftable upper portion and a boom pivotally mounted at the end of that portion. The boom includes an end hinged element, a hinged tip and an intermediate member between the end element and the tip. Each portion of the boom is of a triangular shape and has two lower chords and one upper chord interconnected by rods. The boom is foldable and expandable by a rope system which includes boom supporting ropes and a boom folding rope. The end hinged element is connected to the intermediate member by a shackle having an oblong opening into which a pin is inserted to pivotally connect the end element to the intermediate member.

Abstract: Pressing device for producing compacts from source material in powder form, in particular pulverized nuclear reactor fuel having a die-plate contained in platen and a bore associated with a ram, for receiving source material powder, a filling shoe, and a reservoir for powder connected by a hose to the filling shoe. The device is characterized by a passing wheel in the filling shoe as filling aid means; a tube containing a feedscrew disposed between the reservoir and hose as metering means; the reservoir having a bottom part with a can type place-on part with an opening eccentric to the axis; a coupling part and a cover part are placed on the open part of the can, these parts are also provided with a passageway to the feedscrew eccentric to the longitudinal axis.
