Abstract: Device and method for welding a workpiece (2) having a welding torch (3) which can be mechanically coupled by a coupling element (4) to a hose bundle (5) for supplying the welding torch (3) at least with compressed air or with a protective gas, wherein compressed air applied to the coupling element (4) can be diverted by a diverting valve (10) provided in the coupling element (4) for actuating an actuator (7).

Abstract: A plug part releasably connects a liquid-cooled welding torch to a jack part arranged on a hose package, and a connecting device releasably connects a liquid-cooled welding torch to a hose package. In order to provide a connecting device which is suitable for high welding currents and use with hollow shaft robots, each welding current line on the plug part is arranged around a cooling duct, at least in the region of the front face, and the contact area of each welding current line is arranged axially offset from the orifices of the cooling ducts. On the jack part, each welding current line is arranged around a cooling duct, at least in the region of the end piece, and the contact area of each welding current line is arranged axially offset from the orifices of the cooling ducts.

Abstract: A sample temperature control chamber is described for a benchtop X-ray machine and/or full-protection X-ray machine, which comprises (a) a first chamber part (11) and a second chamber part (12) which can be connected together and are configured so as to form a closed chamber, (b) a sample holder, (c) an integrated temperature control device for controlling the temperature of a sample (P) which is provided on the sample holder, and (d) an active cooling system for dissipating heat from the sample temperature control chamber, the active cooling system comprising a heat sink and/or a fan. A system for X-ray-based analysis of a sample, in particular for X-ray diffraction measurements, is also described.

Abstract: The invention relates to a heating element (25) for liquids to be vaporized as well as a burner (6) of a steam cutting device (1) and a burner (38) of a power-generating device, the element being designed as an induction heater (47) comprising one coil (25a). In order to improve vaporization, the coil (25a) of the induction heater (47) is enclosed in a hybrid construction which is composed of a main part (31) with laterally extending webs (33), and which consists of an easily magnetizable material (35) and a thermally highly-conductive material, a covering element (32) consisting of nanocrystalline materials being arranged on the webs (33), and the easily magnetizable material (35) being designed to be installed on a thermally highly-conductive material (37) of a vaporizer (21).
