A voltage supply for an X-ray tube provides both high and low voltages to the tube. A high voltage transformer using split primary and secondary windings is employed. The high voltage is switched on and off by selectively phasing the voltage across the transformer's secondary coils. Low voltage is coupled from one of two primary windings.

A rotary slide closure for a vessel provided with a fire-proof lining includes a closure block contacting a beveled seat of a seat block and being rotatably mounted relative to the seat block. The closure block and the seat block each have at least one flow-through opening which can be brought into register by turning of the closure block so as to form a pouring channel extending from the center of the closure block. The surface of the seat block forming the beveled seat, faces the interior of the vessel and the closure block contacts the surface forming the bevel seat from the interior of the vessel.

An arrangement for monitoring the oil supply of a lubrication system for heavy machinery has an oil supply conduit, a liquid flow counter designed as a toothed wheel counter with two meshing, outwardly-toothed wheels. One of the wheels has a shaft to which a measuring wheel mounted outside of the oil supply conduit is mechanically connected. An impulse generator allocated to the measuring wheel and measuring the rotational speed thereof, an impulse receiver, and a signalling device to which the impulses are led by means of the impulse receiver complete the arrangement.

An apparatus is provided for continuously processing metal ribbon from ribbon spools of fixed capacity to form spools of processed ribbon. At a dispensing or wind-out reel a continuous metal ribbon is formed by alternately emptying spools from two different positions, joining the ribbon from alternately emptied spools, and replacing each empty spool with a full one while the other spool is being emptied. The continuous metal ribbon is provided to a processing station and, from there, is delivered to a collecting or wind-up reel where a pair of spools are alternately filled with processed ribbon and a full spool is replaced with an empty one while the other spool is being filled. A festoon tower provides a pair of elongated paths of independently variable travel length for ribbon moving, respectively, between the dispensing reel and processing station and between the processing station and collecting reel. This tower provides a continuous movement of ribbon to and from the processing station. One tower path normally stores a predetermined amount of the continuous ribbon and releases the stored ribbon to the processing station during transferring and spool-changing operations at the dispensing reel, thereby providing a supply of ribbon to the processing station during these operations. The other tower path stores ribbon from the processing station only during the transferring and spool-changing operation at the collecting reel and releases the stored ribbon to the collecting reel thereafter, thereby guaranteeing a continuous withdrawal of ribbon from the processing station during these operations.

Ski brake comprising a brake member, a bearing member having bearing lugs for pivotably carrying the brake member, a main leaf spring on the bearing member, an attachment member fixed on the ski having an additional leaf spring thereon, coupling portions on the bearing and attachment members whereby the bearing member can be detachably connected to said attachment member and guided for movement longitudinally of the ski, the additional leaf spring supporting the main leaf spring and the springs being adapted to pivot the brake member about a transverse axis of the ski into braking position. The springs also have detachable interfitting portions to secure the bearing member against movement longitudinally of the ski.

A hose coupling wherein the ends of two hoses are connected to tubular valve bodies having axially extending passages with annular valve seats which face the respective hoses and are normally engaged by disk-shaped elastic valve elements under the action of helical valve springs. A tubular member is reciprocably installed in one valve body at the open end of the respective passage and has a centrally located collar which is flanked by elastic sealing rings. When the two bodies are coupled to each other by a bayonet lock, one end of the tubular member lifts the valve element in the other body off the respective seat and the other end of the tubular member then lifts the valve element in the one body off the respective seat under the action of the valve spring in the other body. When the two bodies are disconnected from each other, the valve spring in the one body engages the respective valve element with the adjacent seat and shifts the tubular member with respect to the one body. The ring at one side of the collar seals the passage of the one body from the atmosphere in all positions of the tubular member, and the ring at the other side of the collar seals the passage of the other body from the atmosphere during and subsequent to coupling of the two bodies to each other.

A tiltable metallurgical vessel arrangement, in particular a steel making plant converter, has carrying trunnions arranged in bearings, one of the bearings being a fixed bearing and one being an expansion bearing, and bearing housings for the bearings; the bearing housings have supporting faces which rest on counter-supporting faces of a base-supported supporting construction; at least one of the bearing housings has two supporting faces arranged at a distance from each other and a strain measuring means connected to the bearing housing between the supporting faces thereof to indicate a sagging of said bearing housing under load.

A bearing assembly for accommodating angular displacements in torque-transmitting trunnions, has a spherical-face-shaped hub on the trunnion and a trunnion receiving bushing, both with toothings meshing with one another. A bearing comprised of inner rings and outer rings is inserted between the bushing and the trunnion. The bearing assembly is particularly suited for a tiltable converter with a carrying ring, in which the bushing is inserted into the carrying ring and the trunnion of the driving toothed wheel protrudes into the bushing.
