Abstract: The invention relates to an expansion valve (10), for controlling a fluid flow, having a valve means housing (12) and at least one valve means (16), which is movably arranged in a valve means housing (12), and an actuator housing (14), in which the electrical drive of the expansion valve (10) is arranged, wherein the valve means housing (12) is formed substantially at least in part of a metal, in particular of aluminum, and wherein the actuator housing (14) is formed substantially at least in part of plastic and wherein the actuator housing (14) is secured on the valve means housing (12) by means of at least one connection element (40). According to the invention, the connection element (40) is formed at least in part as a latching element and/or clip element.

Abstract: The invention relates to a method for producing a machine component (1) for an electrical machine, wherein the machine component (1) is formed with a magnetically conductive material, in which one or more magnetically nonconductive separating regions (4) are provided, wherein the separating region (4) is formed by the introduction of austenite-forming material during a melting process of the magnetically conductive material of the machine component (1), such that an austenitic structure is formed in the magnetically conductive material of the machine component (1).

Abstract: The invention relates to a contact element (10; 10?; 10?; 10??) for providing an electrical contact to an electric machine, particularly in a motor vehicle, comprising: a first contact section (13; 14; 18; 21?) formed from a first material; and a second contact section (11; 17?; 11; 23) formed from a second material that is different from the first material, wherein the first contact section and the second contact section are connected by means of a multi-component connection (16; 16?; 16?; 16??).

Abstract: The invention is concerned with the problem of providing an automatic inspection device, with which it is possible to determine, with little effort and without contact, whether packages, particularly sealed blister packages consisting of a blister container and a cover film, are free of defects. This problem is solved by the use of at least two light sources, which are arranged at a certain distance from one another and each emit a light bundle at a predetermined wavelength range, whereby the emission maxima of the two light sources are offset in relation to one another. The light sources are arranged such that the packages are vertically illuminated. The light reflected by the packages is recorded by a CCD camera and the digital images are stored in a computer, so that they are available in a computer-supported image-processing and documentation system.
