Abstract: An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.

Abstract: A method and device for the controlled tempering of a casting trough integrated between a supply vessel for a molten metal (e.g., copper or a copper alloy), and at least one continuous casting mold. The trough walls and the trough floor of the casting trough are at least partially provided with a lining layer having a specific electrical resistance between 10−1&OHgr;·m to 10−6&OHgr;·m and being resistant to the heat of the molten metal. The lining layer is inductively heated by an electrical heating device arranged around the lining layer.

Abstract: A respiration system is provided with an electrically driven rotary compressor as a gas delivery unit. The system makes a low-noise mounting of the gas delivery wheel possible. The gas delivery wheel can also be washed and sterilized and ensures a reliable separation of the breathing gas from the electric components. The respiration system rotary compressor is mounted magnetically axially and radially during operation.

Abstract: The present invention generally relates to the attachment of a centrifugal mass or a modular clutch to the output end of a crankshaft of an internal combustion engine. For this purpose, axially-oriented gear teeth can be introduced in both parts, e.g. a serration, and there can be a central screw element which can extend into a threaded portion in the crankshaft. The present invention teaches that an axially-oriented spring bias can be applied to both parts to create a reliable connection between the parts of the gear teeth.

Abstract: To continuously cast thin slabs or round ingots from copper alloys, which slabs or ingots have a thickness of 8 to 40 mm, the present method electromagnetically agitates the melt found inside the ingot mold. By properly dimensioning the agitator coil, the agitation power inside the melt is limited to within a range of about 0.5 to 100 W/cm3, while the pull-off rate of the casting strand is limited to within a range of 0.05 to 1.3 m/min. The copper alloys contain up to a maximum of 1% of one element selected from the group consisting of iron, cobalt, manganese, zinc, zirconium, chromium, molybdenum and niobium.

Abstract: The invention relates to a nozzle for the surface treatment of metal workpieces, in particular for the powder build-up welding or thin-layer alloying of highly stressed metal components, which can be selectively connected to a mirror-focused or a lens-focused high-energy beam installation, preferably a high-performance laser installation, by using the cooling medium units, inert gas lines and powder conveyors/extractors provided. In comparison with known laser spray nozzles, the nozzle guarantees a directionally-independent coating of highly stressed metal components with a regular annular distribution of the stream of powder-delivery gas and inert gas supplied.

Abstract: The trouble free operation of a continuous casting process utilizing a moving electromagnetic field for levitation requires information of sufficient accuracy concerning the position and extent of the solidification front inside the continuous casting die. The method and structure according to the invention for monitoring the solidification process employs signals from at least two sensor coils arranged concentrically around the continuous casting die. These signals are fed to a measuring transducer and processed in an appropriate manner. The configuration of the sensor coils inside the levitation coil generating the moving field is particularly preferred.

Abstract: An electromagnetic ball valve for a flow medium under pressure such as a respirating gas for a respirator which must be adapted to use with a respirator which operates at a high frequency in the range of fifty times the usual frequency. Such ball valve must be employed in the breathing gas supply so as to open and close the supply path and a small volume of gas internal of this apparatus permits this control. The electromagnetically ball valve is arranged with the electromagnetic pole pieces in a sheath and the pole pieces include a flow passage in which a ball moves between a seat and an abutment under the control of a separate electromagnetically controlled pole piece. The seat is cooperative with the ball valve with one connection for the flow medium and the abutment includes a connection for the space around the ball valve under another flow connection. With a delivery side connection through the space around the ball and with a seal on the seat it acts as a NC valve.
