Abstract: A heat pump includes a compressor for compressing a coolant and a further heat pump component through which the coolant flows, the compressor being designed to be connected to the further heat pump component in order to convey the coolant via fluid lines, and the compressor and the further heat pump component being designed to be connected to a housing of the heat pump via spring elements in order to reduce transmission of structure-borne sound. The compressor and the further heat pump component are designed to be firmly connected to one another exclusively, on the one hand, via the fluid lines which connect them and, on the other hand, via the spring elements connected to the housing of the heat pump.

Abstract: A heat pump includes a compressor that is connected via two refrigerant-conveying fluid lines to a heat pump component through which refrigerant flows, wherein each fluid line has a longitudinal axis, wherein an imaginary direction vector which coincides with the longitudinal axis points, on the route between the compressor and the heat pump component, at least once in a different direction to an imaginary starting direction vector which begins at the compressor, where it likewise coincides with the longitudinal axis, wherein the longitudinal axis extends in a space having three imaginary, mutually perpendicular planes. The fluid line is shaped such that the direction vector, on the route between the compressor and the heat pump component, and with respect to all three planes, extends so as to be rotated by an angle of more than 180° relative to the starting direction vector at least once.

Abstract: A load selector has a load changeover switch insert with a switching tube rotatable about an axis, at least one switching segment fastened to the switching tube, and at least two vacuum interrupters in the at least one switching segment. Each vacuum interrupter has a switching tube having a respective axially movable contact that cooperates at its free end with an actuating lever. The vacuum interrupters are so arranged in alternation in opposite sense that the movable contacts of the at least two vacuum interrupters are movable with respect to the axis alternately in opposite directions.

Abstract: A spectacle lens for a display device may include a front side, a rear side, a coupling-in section and a coupling-out section. The coupling-out section includes at least two reflective deflecting surfaces arranged next to each other. The spectacle lens guides light bundles of pixels of the generated image to the coupling-out section in the spectacle lens and couples them out of the spectacle lens through the rear side. The spectacle lens includes a main part with the front and rear side, in which a recess extending from the rear side or from the front side to the surface structure is present, into which an insert element is inserted, the first end of which facing the surface structure is formed complementary to the surface structure, wherein the reflective deflecting surfaces lie between the surface structure of the main part and the first end of the insert element.

Abstract: An optical element includes a reflective Fresnel element for deflecting light bundles which are incident on the Fresnel element along a direction of incidence, into a direction of emergence. The Fresnel element includes a plurality of reflective facets arranged next to each other, which are formed curved, and in each case, comprise a first reflective section and an adjoining second reflective section. The reflectivity of the first reflective section is greater than the reflectivity of the second reflective section. The second reflective section of a first reflective facet lies in front of the first reflective section of the directly neighboring reflective facet, seen in the direction of incidence, with the result that the portion of the incident light bundle which is transmitted from the second reflective section of the first reflective facet, strikes the first reflective section of the directly neighboring reflective facet, in order to be deflected.
