Abstract: The invention relates to a metal plate (10) with a screw bore (16) starting at one narrow side of the plate and running parallel to the plate surfaces (10a,b), which screw bore (16) is formed in a simple manner in that first recesses, for example through holes (11), are provided and subsequently the metal portions (13) formed between the recesses (11) are alternately stamped in the direction of the one and the other plate surface (10a, 10b), such that the outer surfaces (14a, 15a) of the stamped parts lie flush with the relevant plate surfaces (10a, 10b).

Abstract: A combination for facilitating the assemblage of signal processing equipment in which a first assembly unit can be secured on a base plate either parallel or at right angles to the base plate and wherein a second assembly unit can be arranged at right angles to the base plate.

Abstract: A planar good electrical conductor part, having a connection lug connects to the outer conductor of a coaxial cable. The part has near its circumference an annular array of through-holes through which contact pins can be passed and brought into contact with the part. A central contact pin can be passed through a recess arranged approximately in the center of the part and can be brought into contact with the inner conductor of the coaxial cable secured to the part by the lug and aligned with the central recess.

Abstract: A sliding drawer for storage of instructions in electronics racks or the like.
