Abstract: An optical conductor includes a transparent fiber of synthetic material, a reflective layer and a sheathing of synthetic material. The optical conductor is rotationally symmetrical relative to a fiber axis. The property and the position of the end race of the fiber are of decisive significance for the optical quality of a plug connection of two optical conductors. The ends of the optical conductors must be arranged at a minimum spacing one from the other and the fiber axes must be oriented exactly one onto the other. Usually, the end of the optical conductor is mounted in a ferrule, in which case it is important that, in a plug connection, the one end face is positioned exactly relative to the other end face. The projecting fiber end is severed by a laser beam, wherein an end face arises, which displays the required mechanical and optical qualities.

Abstract: A crimping press having a motor, a gear and first guides, at which a crimping ram is guided, arranged at a frame. A shaft driven by the gear has an eccentric spigot at one end and a resolver for the detection of the rotary angle coupled on at the other end. The crimping ram includes a sliding member guided in the first guides and a tool holder with force sensor and retaining fork.

The tool holder usually actuates a tool which, together with an anvil belonging to the tool, produces the crimped connection. For calibration of the force sensor, a crimping simulator is used in place of the tool. For input of operational data and commands to a control, an operating terminal has a rotary knob and a keyboard. A display is provided for visualization of data.

Abstract: In a housing two ultrasonic measuring transducers are arranged opposite of the two end faces of a test tube. The test tube providing a measuring section penetrates a separating wall and interconnects two distribution chambers of the housing. The fluid to be measured flows through the test tube and influences the transit time of the ultrasonic impulses released and received by the measuring transducers. The test tube provides a constant cross-section of metallic material along the length of the measuring section. The connection between the test tube and the separating wall consists of a nonmetallic material, thus preventing echoes which may penalize the measuring accuracy.
