Abstract: The device for use in an explosive atmosphere zone has a device housing and at least one energy supply part that is provided with at least one battery or at least one rechargeable battery as well as energy-associated supply contacts. The energy-associated supply contacts interact with device-associated supply contacts when the energy supply part is connected to the device. The energy-associated and device-associated supply contacts have connected upstream thereof switches that, prior to separation of the energy supply part from the device, can be controlled by a circuit such that the switches deenergize the energy-associated and the device-associated supply contacts.

Abstract: The invention relates to a current-carrying lead, in particular a connecting lead and a heating tape (5), for a plug connector, which current-carrying lead has at least two strands (49, 50) that are partly surrounded by electrical insulation (47). The current-carrying lead is provided with at least one reservoir (53) for an electrically insulating medium (54). The reservoir (53) is closed by least one plunger (55), by means of which the sealing medium (54) can be forced through at least one outlet nozzle (57) into at least one sealing chamber (58 to 60). The plug connector having a current-carrying lead (3, 5) has a sealing device (36) having a sealing body (66). Said sealing body has an elastically deformable sealing part (71) that can be elastically deformed by means of a wedge-type slider (77). The wedge-type slider (77) has a conical face (82) that interacts with a conical face (76) of the sealing part (71).

Abstract: An electric device has a plug connection provided with a plug that has at least one contact pin and further provided with a mating plug receptacle that has at least one contact tube. A closure device is arranged on the plug receptacle and has a closed position for protecting the at least one contact tube. The closure device is moved by the plug into an open position when the plug is inserted into the plug receptacle, wherein in the open position the at least one contact tube is released.

Abstract: A device has a fastening device providing a releasable locking action on a support rail and further has a securing lever having a locked position in which the releasable locking action is secured against release. The device has a housing, wherein the fastening device is slidably arranged on a bottom plate of the housing. The fastening device has a base plate with at least one lock member interacting with the support rail. The at least one lock member has a cutout for receiving a transverse leg of the support rail and further has a ramp for the support rail.

Abstract: An electric device assembly has a frame housing provided with electric connectors and an assembly housing containing electric and/or electronic components and adapted to be inserted into the frame housing. A plug connector that has at least one contact tube and at least one contact pin engaging the at least one contact tube is provided. A lock system acting on the plug connector has an actuator that is pivotable about a pivot axis. The actuator is non-detachably secured on the frame housing by a blocking device. The blocking device has a blocking member arranged on a support wall of the frame housing. The blocking member engages a blocking member receptacle that is disposed on the actuator. The actuator is pivotably connected to the support wall by a bearing part received in a bearing receptacle in the support wall.

Abstract: Indicating light for optical display, comprising a housing including electrically conducting components, a light-emitting diode, a light rod and a round cap.

Abstract: An electrical structural part with an electrical or electronic structural element provided on a basic body and with an encapsulation enclosing the structural element tightly and free of voids, the material structure of the encapsulation being intimately fused with the material structure of the basic body.

Abstract: The invention relates to a device for fiber optic temperature measurement with an optical fiber having a radiation coupling in area and a detector-associated radiation coupling out area. Such a device is characterized in that the optical fiber is constructed with high transmission in the infrared (IR) spectral range, particularly in the range from approximately 2 ?m to approximately 20 ?m.

Abstract: The invention relates to a method and device for determining the quantity of fluid discharged from a tank via a line system. To this end, the difference between the quantity of fluid contained inside the tank before fluid discharge and the quantity of fluid remaining inside the tank after fluid is discharged is calculated. In addition, a measuring device measures the quantity of fluid, which is contained inside the line system and which is taken into consideration when determining the discharged quantity of fluid.
