Abstract: In an ingot mould casting device for casting a melt, the ingot moulds (1, 1a, 1b) of the individual ingot mould units (35, 36, 37) are movable in a U-shaped clamp (13), wherein at the free ends (43) of the U-shaped clamp (13) there is provided an ingot mould holding- and pulling-apart mechanism. With the aid of this ingot mould holding-and pulling-apart mechanism, the ingot moulds are opened so far, after casting has been effected in the casting position, until the resistance during pulling-apart of the ingot mould (1, 1a, 1b) drops to the resistance with respect to the shifting of the ingot mould half (1b) movable on the guide rods (2). In a second phase, the movable ingot mould half (1b) is moved completely away from the non-movable ingot mould half (1a). The discharged parts fall onto the conveyor belt (18). The entire operation from the actuation of the starting button (42) of an ingot mould arrangement can take place automatically.

Abstract: In a process for reducing the NO.sub.x content of waste gases by a catalytic reduction of the NO.sub.x gases using a washable catalyst, a solution is to be provided, with which, while retaining the advantages of the procedure known from the German Offenlegungsschrift No. 3,107,117, this danger is avoided and which is suitable for use with a large range of waste gases, that is, which in particular is not restricted to nitric acid plants. This is accomplished owing to the fact that the reduction is carried out using unsaturated hydrocarbons at a temperature equal to or less than 180.degree. C.

Abstract: A molded tapping member for connecting a branch line to a pipeline includes a U-shaped saddle piece with a shell-shaped bight section and a pair of laterally spaced legs each extending outwardly from an opposite end of the bight section. The legs are formed of partial sections connected to one another by a film hinge. After positioning the tapping member on the pipeline by moving it radially toward the pipeline axis, the bight section and the legs are pressed around the pipeline. A heating wire mat is incorporated into the U-shaped saddle piece so that it fits closely around the pipeline for welding the tapping member to the pipeline. With the construction of this saddle piece a uniform welding pressure can be established during the welding operation.

Abstract: In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted. A second sleeve is connected to the first sleeve and is threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves. The third sleeve is axially displaceable between a first position and a second position. In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws. When the third sleeve is displaced into the second position, the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.
