Abstract: An overload safety coupling, especially for the main drivetrains on rolling stands, which bridges a toothed spindle section and a spindle section with a permanent seat. The coupling includes a rotating-and-sliding sleeve, which has internal toothing at one end to hold the spindle section in a way that allows axial displacement. At the other end, the sleeve holds an inner sleeve, which is permanently seated on the spindle section. A pressure sleeve and a pressure gap pretensioned with pressure fluid produce a nonrotatable connection between the rear sleeve-like extension and the inner sleeve, which frictional connection gives way in the event of an overload.

Abstract: In a method for manufacturing a printed end product containing a single printed product or several printed products, collected astraddle and supplied sequentially, and bound by stitching, the printed products are collected in a predetermined sequence required for forming the printed end product along a common conveying path. Subsequently, the printed products are stitched. A circulating collecting support is provided which is supplied by a feeding device with spread-apart printed products. After the collecting step is complete, the collected printed sheets are moved on the conveying path to the stitching location.

Abstract: The invention relates to an actuator for an electric push-button switch (30) comprising a housing shell (10) in whose shell opening (13) a holding plate (20) is placed. A holding suspension, together with outer stops (21) and outer counterstops (11) between the holding plate (20) and the holding housing permit the non-actuated holding plate (10) to be pressed into a defined outer position of rest (20.1). A push-button switch (30), which is arranged in the housing shell (10), is, together with its switching element (31), located in an extended position (30.1) that is effected by a switch suspension (33). The aim of the invention is to provide an economical space-saving design. To this end, the switch suspension (33) of the push-button switch (30) is simultaneously provided with the function of providing the holding suspension of the holding plate (20).

Abstract: A device for recirculating oil from the end face of the barrel and the peripheral surface of the roll neck of rolling mill rolls. A sealing race arranged between the bearing elements and the end face of the barrel is mounted on the roll neck. A first conical ring body has a conical outer surface and a cylindrical inner surface that is seated on the outer surface of the sealing race and is sealed from the race, whereby inclination of the conical outer surface towards the end face runs towards the roll axis. A second conical ring body is rigidly mounted in the bearing housing and has a conical inner surface, which conical inner surface is arranged some distance opposite the conical surface of the first conical ring body, such that the two conical surfaces form a hydraulic pump gap that conveys oil away from the end face.

Abstract: The invention relates to a device for drilling a bore in the ground, comprising a drive system with a connecting rod assembly that extends from the drive system into the ground. The end of said assembly pointing towards the face or base of the bore is connected to a tool head (40). The device also comprises several tools (41) that are located on the tool head (40) and work on the face or the base of the bore. The inventive device is characterised in that each tool (41) comprises an excavation disc (45) and elements that cause the excavation disc (45) to oscillate during operation.

Abstract: A plug-type connection arrangement for a hose and a pipe, the connection arrangement comprising a sleeve having an outer wall and an inner wall, wherein the hose is insertable from an end of the sleeve and is clampable in the sleeve, wherein the sleeve has at another end thereof a first annular groove with an open resilient connecting ring which extends over more than 180° and is lockable to the sleeve and the pipe, and a sealing ring for sealing the sleeve relative to the pipe in a connected state of the pipe and the hose, the connecting ring being comprised of a plate spring ring with inwardly directed flanges at both circumferential edges thereof, wherein the flanges of one circumferential edge are engageble in the first annular groove and the flanges of the other circumferential edge are engageable behind a holding rib on the pipe, wherein the sealing ring is mounted in a second annular groove formed by the inner wall of the sleeve and the axially inner wall of the first annular groove, and wherein an end

Abstract: The invention relates to a method, device and a circuit for detecting surface defects such as cracks, fractures and the like on a roller (2) for a rolling mill (1), in particular on the working rollers (2a) which are mounted with support roller (2b) on a vertical stand (3).
