Abstract: A rotary coupling for connecting a control device housing to a support arm or an elbow of a support arm system, having a rotating ring fixedly connected to the control device housing and partially rotatable in relation to a coupling piece which is connected to the support arm or the elbow. For equalization of tolerances caused by insufficient twist rigidity of the support arm system, the invention provides that the coupling piece forms a peripheral bearing ring which is convexly arched outwardly and is received in and supported by two shell rings. The shell rings are connected to each other and have concavely arched bearing surfaces. The shell rings are rigidly mounted on the bearing ring of the coupling piece by a clamping cheek. The rotating ring is rotatably maintained on the shell rings by a support ring which is connected to the shell rings.

Abstract: An automatic pull-in mechanism for drawer guides consists of a guide rail and a runner rail, which are made longitudinally displaceable relative to one another by rolling bodies. On the guide rail there is disposed a component that can toggle between two end positions and is biased bistably toward the toggle end positions by a spring system, and has an open-ended slot for a projection projecting downward from the runner rail. The projection and the toggling component are so disposed relative to one another that upon a displacement of the runner rail from the drawer-open position to the drawer-closed position, as the projection approaches the latter it enters into the slot and then, after passing over the dead center of the toggling component, it is carried resiliently by the slot into the drawer-closed position.

Abstract: A device for bridging expansion joints in bridges or the like is provided with parallel lamellae arranged at right angles to the longitudinal axis of the traffic route. The lamellae are supported on at least two inclined traverses which are pivoted and movably supported at both sides in the joint edges, which bridge said joint diagonally with respect to the longitudinal axis, and are rotatably and movably guided in sliding drag bearings at the bottoms of the lamellae. The inclined traverses are arranged parallel to each other, whereby the support width of the lamellae is always uniform. At least one longitudinal traverse which is movably connected the longitudinal direction with each lamellae via sliding bearings fixed at the bottoms of the lamellae is provided for, preferably at the edge, for taking up the forces which inevitably occur due to movements of the bridge superstructure.

Abstract: A method of manufacturing a coil for a transformer and in particular a high voltage transformer in which the starting end of a wire with a bondable thermoplastic sheet is electrically conductively connected to an axially slit sleeve of non-magnetic metal which sleeve is placed on a rotary winding tool to form an essentially cylindrical wire winding directly on the sleeve with the end faces of the sleeve extending beyond the winding. Heat is applied to the winding to bond the individual turns to each other. One end of the sleeve carrying the winding is placed on the bottom of a casting mold and the end of the wire remote from the starting end is connected to a terminal. A casting compound is introduced into the mold to anchor the connecting terminal. The outside of the casting compound is provided with an electrically conductive casing which is electrically connected to the sleeve.

Abstract: In a mechanical process for producing a fish product which may be described as a double fillet including head and tail, the intestines and the bone structure are removed completely and the gills at least partially. The processing is performed from the tail end and comprises the steps of making incisions on both sides of the belly spokes along the whole length of the fish from the ventral side while simultaneously removing the intestines and the gills, while subsequently the bone structure is cut out from the fish body by cutting over the ribs. The obtained double fillet can be folded together by folding down the double fillet halves to form an apparently complete fish.

Abstract: A process and a device for the continuous chipping of timbers of different length. To increase the chipping performance, in the execution of the sawing cut or directly thereafter, at least one supporting element for supporting the leading end face of a long timber pack and the posterior end face of a short timber pack is directed into the sawing plane. Directly adjoining the short timber pack, a just sawn-off short timber pack, together with the supporting element enclosed between them, is conveyed forward by one advancement cycle in the same direction. The supporting element, following the conclusion of the advancement cycle, is conveyed back into the directing-in area of the sawing plane, and each short timber pack is supportingly transported, free from any structural distortion, up to the chipping tool.

Abstract: The invention relates to a connection assembly between a support, for example a body part of an automotive vehicle, and a plate element, such as a wall covering, including a lower holding component insertable into an opening of the support. The lower holding component carries a center component whose upper portion comprises a spherical segment which can be clipped into an opening in a tubular section of upper component. The opening which receives the spherical segment has an internal prof ile defined by spring elements spaced about the interior of the tubular section. The spring elements hook behind the spherical segment, and between the spring elements there are arranged spacer elements acting upon the spherical segment to maintain it centered relative to the spring elements.
