Abstract: A contact device includes a first plug connector, which for forming a plug contact is pluggable onto a corresponding second plug connector of a first component, and comprising at least one first abutment section, which for forming a pressure contact is pressable against a second abutment section of a second component and/or of an additional element that is connectable to the second component. At least one spring section is provided between the first plug connector and the first abutment section and/or between a fastening section of the additional element and the second abutment section. The spring section presses the two abutment sections against one another with an elastic force when the two components are electrically connected to one another. The first plug connector is designed as a push-on sleeve, so that it is pluggable onto a second plug connector, designed as a plug, of the first component.

Abstract: A motor vehicle quick coupling for a fluid connection in a motor vehicle includes a coupling body in which a fluid line is formed through which a fluid can flow. The quick coupling has a first fluid interface which is designed such that the quick coupling can be connected directly to a fluid-conducting component of the motor vehicle, in particular to a radiator, such that the component supports the quick coupling. The quick coupling has a second fluid interface which is fluidically connected to the first fluid interface via the fluid line. The quick coupling includes a valve which has a valve closure element that extends into the fluid line.

Abstract: In accordance with the invention a method for the manufacture of an erosion protection layer on a metallic substrate is proposed in which a material is welded onto the metallic substrate (2, 2?). The material is a steel which contains at least 0.1% carbon and at least 12% chrome. The material is applied to the substrate (2, 2?) by laser deposition welding. A component (1, 1?) is further proposed by the invention with a metallic substrate (2, 2?) and an erosion protection layer (3, 3?) applied on the substrate (2, 2?), wherein the erosion protection layer (3, 3?) is manufactured using a method in accordance with the invention.

Abstract: A portable device (1) with at least one optical output device (2) for displaying at least process data of a machine, a robot or a technical process, with at least one input device (3) for at least intervening in the operating functions of the device (1) and/or for operating the machine or robot or technical process, and having a safety switch device (12) for preventing the output of undesirable, unintended control commands for the machine, robot or technical process. The output devices (2) and input devices (3) are connected to a control device (14), which is accommodated in a housing (7) that is unbreakable as far as possible and at least one communication interface (17) is provided to an external control device disposed at a distance away. Several of the input and output devices (2, 3) are functionally combined by means of a touch-sensitive screen (4) in the form of a touch-screen (5) and the touch-sensitive screen (4) extends across substantial regions of the surface of the housing (7).

Abstract: The invention relates to a safety switch unit (1) for electrically controlled machines for use in combination with the actual control elements of the machine control system in a hand-held application or for manual control, with at least one operating element which is displaced relative to a mounting frame (8) in accordance with the switching function desired by a user, which is designed to change the switch status of at least one electric switch element, the safety switch unit (1) having at least one switch position which is maintained only as long as a sufficiently high operating force is applied to the displaceable operating elements.
