Abstract: Wire positioning devices (1) for positioning an electrical wire (2) in a processing device, include a wire guide (4) for receiving the electrical wire (2) and a lowering device (5), movable vertically in relation to a first longitudinal axis (45) of the wire (2) received in the wire guide (4). The lowering device (5) has a press piece (6), spring-loaded via at least one spring element (15), and is provided so as to be contacted against the wire guide (4), the spring element (15) being arranged in a tube (16). Also disclosed are methods for lowering thin wires (2) and for positioning them in an oscillation-damped manner, wherein a wire positioning device (1) or a processing device are employed.

Abstract: The invention relates to a twisting apparatus (1) for twisting of electrical or optical lines (2) such as wires, cables, line bundles, optical fibers etc. in particular a cable twisting apparatus, comprising a base (5) and a twisting head (3) which can be rotated relative to the base (5), which is configured to grip the lines (2) to be twisted at their first ends, characterized in that the twisting apparatus (1) comprises a second twisting head (4) which can be rotated relative to the base (5), which is disposed opposite the first twisting head (3) and which is configured to grip the lines (2) to be twisted at their second ends opposite the first ends and that the second twisting head (3) can be rotated in the opposite direction to the second twisting head (4). The invention also relates to a method for twisting lines.

Abstract: The invention relates to a conveying device for conveying electrical or optical lines (8) such as wires, cables, line bundles, optical fibers etc. comprising a gripper (3) for gripping a line (8), wherein the gripper (3) is displaceable along a guide (1) between a first position (5) and a second position (6), characterized in that in the region of the first position (5) and in the region of the second position (6), respectively one active interface is provided which is configured to come into operative communication with the gripper (3) and bring this into a closed position or open position when the gripper (3) is located in one of the two positions (5, 6).

Abstract: In order to develop a method for determining a measured value of a target measured variable of a multiphase flow, in particular, of a two-phase flow, wherein a value of a pressure of the multiphase flow is measured as a primary measured variable by means of a measuring device, with which a desired target measured variable of a multiphase flow, for example, the total mass flow can be determined in a simple manner from a primary measured variable, it is suggested in accordance with the invention that a time development of the primary measured variable be measured, the measured time development of the primary measured variable be compared with reference time developments of the primary measured variable, with which a respective reference value of the target measured variable is associated, and the measured value of the target measured variable be determined from the reference values of the target measured variable as a function of the result of the comparison of the measured development of the primary measured v

Abstract: Shaped, activated Raney metal fixed-bed catalysts are obtained by molding a powder of at least one catalyst alloy, comprising at least one Raney process metal as catalytically active component and a leachable alloy component, and a powder of pure Raney process metal as binder with the addition of a shaping aid and pore-producer and subsequent calcination at temperatures below 850.degree. C. During calcination the shaping aid and pore-producer are burned away. Catalyst alloy powder and binder powder thereby sinter together to give a mechanically stable and porous molded item. This molded item thus consists of particles of catalyst alloys which are bonded by the powder of pure Raney process metal. It has no catalytically inactive, ceramic or glassy binder. The surface layer of the molded item is activated by leaching the leachable alloy component contained in the catalyst alloys with caustic soda solution.
