Abstract: A brake caliper formed without machining for a spot-type disc brake, in which the brake caliper after subsequent machining forms a floating caliper, has a braking force generator (12) and an opposite-lying abutment (22). For the non-machining forming of the brake caliper (10) two mould parts (34, 36) each partially receiving the brake caliper (10) are used, in which support surfaces (Q1, Q2, Q3, Q4, Q5) and action surfaces (S1/2, S3, S4, S5) are formed on the brake caliper (10) in such a way that the brake caliper (10) for the subsequent machining is supportable by its support surfaces (Q1, Q2, Q3, Q4, Q5) in a defined manner and clampable by means of clamping forces acting upon its action surfaces (S1/2, S3, S4, S5). To keep the extent of the subsequent machining to a minimum, during the non-machining forming the abutment (22) and the support surfaces (Q1, Q2, Q3, Q4, Q5) of the brake caliper (10) are formed in one and the same mould part (34).

Abstract: The device for inserting at least one semiconductor component into a receiving portion, particularly into a test socket for testing the electric function of the semiconductor component, comprises at least one receiving space (46) for the semiconductor component (12), the receiving space (46) comprising a receiving opening (56). Further, the device comprises at least one moveable member (14) supported on element (34) whereby semiconductor component (12) is carried in a moving direction (58) through said receiving opening (56) into the receiving space (46). The pushing element (34) comprising a gas cushion generating means (62) for generating a gas cushion (60) is adapted to support the semiconductor component (12) at least in the receiving opening (56). Heating and cooling means (68) are provided by which the air out-flowing as an air cushion (60) can be brought to a desired temperature (FIG. 2).

Abstract: Toothed-wheel shaped particles are used as catalysts in the dehydrogenation of hydrocarbons, particularly ethylbenzene to styrene.

Abstract: Process and catalyst for the selective catalytic hydrolysis of the inorganic sulfur compounds COS and/or CS.sub.2 being present in CO containing process gases. The process gas is passed over an alkalized chromium oxide-aluminum oxide catalyst in the presence of H.sub.2 O.
