摘要:
A metallurgical probe has a probe longitudinal axis and an open end face. The probe is fitted within a bearing point in such a manner that the open end face faces a predetermined insertion direction. The bearing point has probe centering elements to hold the probe in a predetermined probe position as seen transversely with respect to the probe longitudinal axis. A device inserts an end of the contact rod into a contact rod centering device, in an insertion direction running transversely with respect to the probe longitudinal axis, until the end of the contact rod is positioned, on account of the insertion into the contact rod centering device, in a predetermined contact rod position, in which the end of the contact rod is opposite the open end face. The contact rod is then moved in a direction of the probe longitudinal axis and is inserted into the probe.

In order to be able to carry out a multiplicity of continuosly recurring activities at a continuous casting plant having at least one multifunction robot for implementing a plurality of different process-controlled or automated interventions at the continuous casting plant, at least one working region at the continuous casting plant and at least one multifunction robot assigned to each working region. The multifunction robot is arranged on a pivotable arm at a rotary column fastened to the pouring platform of the continuous casting plant and the robot can be pivoted with the pivot arm between a retraction position and a working position. The robot is also movable with respect to its arm.

A device for interchangeable connection of a casting tube to a spout of a melt vessel with a sliding closure fastened on a melt vessel. The closure is formed by at least one stationary closure plate and a closure plate that can be displaced relative thereto, wherein the displaceable closure plate is coupled to a sliding drive system and carries the casting tube. To improve the changeover process of a casting tube and to make it safer, the displaceable closure plate carries a connecting ring for the centered accommodation of the casting tube and the displaceable closure plate carries a changing device for the casting tube. The changing device is synchronously displaceable with the displaceable plate. A tensioning device presses the casting tube onto the displaceable closure plate.

The metal substrate of an electrophotographic member is provided with a selenium-tellurium alloy layer containing 5-30% tellurium, 10-5,000 ppm of a metallic element of the fifth main group, and 10-100 ppm of a halogen. A preferred embodiment contains 15% tellurium, 40 ppm arsenic, and 40 ppm chlorine. The addition of the metallic element of the fifth main group to the selenium-tellurium alloy results in a stabilization of charging potentials in multicycle operation.If the metal substrate is an aluminum drum, the electrophotographic member can be used as a copying drum in high-speed copiers.

摘要:
A cooling system for annealing material (4) in the form of plates, strips or bulk material moving on a transport means (5) consists of a plurality of zones (1, 2, 3), in which the annealing material (4) is treated on its lower and/or upper surface with an oblique blast of cooling medium in the form of air or gas emerging from nozzles of nozzle bars (10, 10a, 10b) fed by a compressor-type blower (7, 8, 8a, 11). In order to reduce the required amount of cooling medium, and to reduce the technical effort involved, only the last zone (3) disposed on the outlet end for the annealing material (4) is connected to the supply (7) of pressurized fresh cooling medium. In this zone (3) a collecting fan (8, 11) is provided, which upon formation of the oblique blast urges the cooling medium into a distribution box (9). To the distribution box (9, 12) the nozzle bars (10) of the penultimate zone (2) are connected. This zone is likewise provided with a collecting fan (11) including distribution box (12) for the preceding zone (1). This set-up or arrangement is repeated up to the first zone (1) disposed on the inlet end for the annealing material (4), whose collecting fan (13) finally opens to the outside.

A system for the heat treatment of metallic annealing material (1, 12) comprising a distributor (3) for the heating or cooling medium consisting of air or a gas, where for the formation of an oblique blast the distributor (3) has tubular or slot-shaped nozzles (4, 4a) directed against the annealing material (1, 12) possibly lying on a transport means (2). For changing the distance of the nozzle orifice from the workpiece surface, the nozzles (4, 4a) are provided with retractable extensions (5, 5a) for increasing the distance between nozzle orifice and annealing material (1, 12).
