Abstract: A sewing unit with a feed device for a fabric holder with support elements that can be moved along a guide and are connected to a drive each for feed means acting on the fabric holder. A fabric being sewn can be transported to or removed from the sewing machine by the feed device over any desired distance and the feed movement of the fabric being sewn can be brought about without problems during passage through the stitch formation site of the sewing machine even at very high stitch frequency because of the favorable dynamic properties. The guides are arranged in the same direction, and the support elements can be driven synchronously for a movement of the fabric holder in parallel to the guides, and at mutually different velocities for a movement in a direction deviating from the direction.

Abstract: A miniature motor comprising a case formed into a bottomed hollow tubular shape and having permanent magnets fixedly fitted to the inner circumferential surface thereof, a rotor consisting of an armature and a commutator, and a case cover engaged with an open end of the case and having brushes making sliding contact with the commutator, and input terminals electrically connected to the brushes, in which fixing ribs are provided on the inner circumferential surface of the case, extending along the axial direction of the case; the edges of the permanent magnets formed into an arc-segment cross-sectional shape being caused to make contact with the side edges of the fixing ribs to fixedly fit the permanent magnets to the inner circumferential surface of the case; projections formed integrally with the permanent magnets along the edges of the permanent magnets are provided facing the surface of the fixing ribs.

Abstract: Process for the autonomous positional control of guided missiles, which are to be launched from a carrier plane, but without the cooperation thereof, wherein data on the instantaneous position of the guided missile, as well as flight and target data are fed into a computer of the guided missile already on the ground. The initial data fed into the computer are continually updated with changing values from the inertial navigation and additional navigational aids and are further calculated to achieve autonomous flight guidance and self-guiding of the missile. An uninterruptible power supply of the guided missile is maintained beginning from the moment of data reception.

Abstract: A medical technical compression implant (1) for the surgical repair of damage to the spine, especially in the cervical region, includes two clamp jaws (3, 4), which are directed toward each other, are hook-shaped, are connected by a threaded spindle (2), and can be compressed while reducing the distance (B) between them. A wrench profile (9) for attaching a rotating tool in an interlocking manner is arranged at the threaded spindle (2) between two threaded sections (7, 8) with right-hand threads and left-hand threads, respectively. Both the clamp jaws (3, 4) have threaded nuts (5, 6), which are pivotably mounted from bodies, with diametrical threaded bores for screwing on the threaded sections (7, 8). The threaded nuts are mounted in cylindrical transverse bores of the clamp jaws (3, 4). The bore walls (21) are provided with diametrical openings (22, 23) for passing through the threaded sections (7, 8) of the threaded spindle (2).
