Abstract: An apparatus for mounting a conductor terminal including an insulated housing and a bus bar on a support rail is characterized by a solid metal contact base connected with the bus bar and adapted for electrically and mechanically connecting the bus bar with the rail. The base includes a pair of integral hook portions for clamping with the edges of the rail and at least one intermediate resilient prong extending longitudinally from the base. When the hook portions are clamped onto the rail edges, the prong is biased against the rail to retain the connector in position on the rail.

Abstract: In a measuring device which serves to measure a geometrical variable with the use of a sensor which is fed an alternating measuring current of constant amplitude by a regulated, phase-dependent current source. An alternating supply voltage and an alternating measuring voltage tapped by the sensor via a feedback path of the current source is superimposed in a superimposition stage, which belongs to the current source and downstream of which a reference element for determining the alternating measuring current is connected, to form a total voltage present at the reference element. In order to match a characteristic representing the relationship between the alternating measuring voltage and the geometrical variable to a prescribed characteristic curve, at least one of the alternating voltages fed to the superimposition stage is varied. The variation can concern both the amplitude and the phase.

Abstract: The invention relates to a nozzle for a tool for working material, for example for laser cutting. The nozzle contains an electrically conducting nozzle body (2), at the tip of which is arranged a nozzle electrode (12) electrically insulated from it. A cap element (15) accomodates the nozzle electrode (12) and is in engagement with the nozzle body (2). At the same time, the cap element (15) presses the nozzle electrode (12) against an insulating body (9). The cap element (15) and the nozzle electrode (12) are insulated from one another by means of an electrically non-conducting layer, making possible shielding of the nozzle electrode (12) a long way into the tip region. The cap element (15) furthermore protects the nozzle electrode (12) from lateral forces in order to avoid damage to the insulating body (9) which accommodates the nozzle electrode (12).

The screw clamping mechanism and the U-shaped receptacle are locked into position since the collar includes in the upper area thereof lateral shoulder projections which abut against the side edges of the side walls of the U-shaped receptacle upon activation of the screw to displace the clamping mechanism downwardly into the receptacle.

Abstract: A heavy-duty electrical plug connector is characterized by a label plate slidably connected with the connector housing for movement between retracted and extended positions. A label containing information designating the poles of the plug connector is provided on the plate. For wiring the connector, the plate is pulled to its extended or reading position wherein the labelled designations of the poles of the connector are visible. After wiring, the plate is slid beneath the housing to its retracted position where it takes up little space and where it does not interfere with wiring work on other connectors.
