Abstract: The invention relates to an electrohydraulic pressure control device, in particular a brake-slip control device (1) for motor vehicles. The inventive device comprises one or more electromagnetically actuatable hydraulic valves, which are accommodated in a valve block (6) and which are provided with valve domes. Said valve domes at least partially project above the valve block (6) in the direction of a valve axis (8) and each engages inside a coil opening (14) of an electric coil (12) held by a coil support (10). The hydraulic valves are also provided with contact elements (20), which project away from the coils (12) and through openings (34) of a top plate (32) and which are provided for electrically controlling the coils (12). The invention provides that at least some of the coils (12) are held with forceless motional play, however, in a position-oriented manner on the coil support (10) in a plane extending perpendicular to the valve axes (8), and after their alignment, which results from the valve domes engaging inside the associated coil openings (14), they can be immovably fixed in the aligned position.

Title: Under-powder welding powder with alkali salt coating - ensures uniform weld
Inventor: ERDMANN-JESNITZER FRIEDRICH PR
IPC: B23K35/362
Filed: 1970-05-12
Abstract: Powder granules are contacted with aqs. soln. or melt of alkali salt(s), e.g. NaCl, by spray or washing process, so that they have alkali coating after drying, which promotes ionisation of arc on welding, and so that Cl2 gas formed by melting and decomposition covers powder, welded and substrate and exerts favourable and reducing effect on oxidic coatings, formed or forming to ensure controlled melting with more uniform material transition even for surfaces which are not free from under-powder welding e.g. sheet steel of Al and other alloys based on (non)ferrous metals, which form oxides nitride or surface coatings. This technique overcomes difficulties in coating such powders with alkali metal(s). Powder covers arc and protects weld and materials from surrounding gases (esp. O2 and N2) and improves arc stability.
