Patent DE-3333259-A1 (DE)
Title: Clamp with a pivotable counter-bearing
IPC: B25B5/10
Filed: 1983-09-15
Abstract: In a clamp with two yoke parts (2, 3) projecting at right angles from a rail (1), one of which is a clamping member (threaded rod 4) which is adjustable substantially parallel to the rail (1) and the other of which is a counter-bearing (15) opposite to the clamping member, the counter-bearing (15) has the cross-section of a segment of a circle and rests with its cylindrical outer surface on the cylindrical bearing surface of a bearing block (7) attached to the assigned yoke part (2). The pivotable counter-bearing (15) guarantees a perfect contact on the surface of clamped workpieces, even when the rail (1) is bent under the influence of strong clamping forces. As a consequence of the pivot axis (17) of the counter-bearing which is situated above the pressure surface (23) of the counter-bearing (15), such clamping forces (arrows 24) always tend to bring the counter-bearing (15) into a stable equilibrium position, as a result of which, despite the pivotability of the counter-bearing (15), the creation of jolting moments which could make it considerably more difficult to manipulate the clamp is avoided. <IMAGE>

Title: Wedge-type collet chuck
Inventor: PRUDEN SAMUEL H
IPC: B23B31/177
Filed: 1983-10-27
Abstract: A wedge-type collet chuck has grooves in the sides of each gripping jaw and in adjacent sides of the guide path in the chuck body; the grooves in all the gripping jaws for a given angle with a common plane perpendicular to the chuck axis, in which all the gripping jaws move, and the grooves in each guide path lie in a plane perpendicular to the common plane and to the centre plane of the allocated guide path in which the chuck axis lies. A gripping-jaw actuating device is movably guided in the chuck body in the direction of the chuck axis and accommodates sets of driver wedges. The wedges of each set are accommodated with a sliding fit in the grooves in one gripping jaw and the grooves in the associated guide path. During a return or forward movement of the actuating device, the grooves and driver wedges interact in such a way that the clamping jaws are moved towards and away from the chuck axis.

Title: Wiper system for windows of motor vehicles
Inventor: MOENCH FRANZ
IPC: B60S1/24
Filed: 1983-11-26
Abstract: A system is proposed which serves to wipe windows of motor vehicles. The wiper system comprises two wiper elements which rest against the window to be wiped, are moved so as to oscillate in opposite directions and partially overlap in the position of reversal of the oscillation when they approach one another. The wiper system also has a drive unit which has a power take-off shaft to which two journals are connected, which journals are each part of an oscillation transmission, each of which is assigned to one of the two wiper elements. The oscillation transmission which is assigned to the wiper element which moves into the outer reversal position has an intermediate transmission which is constructed as a three-point joint. The first joint of the intermediate transmission is arranged fixed to the frame. A push rod which is attached to one journal in an articulated fashion is coupled to the second joint and a second push rod is attached in an articulated fashion to the third joint and leads to a rocker connected to a wiper shaft, on which rocker the wiper element which moves into the outer reversal position is attached via a wiper arm. So that the oscillation movement of the outer wiper element can be matched to the oscillation movement of the inner wiper element, the arrangement of at least the two joints of the three-point joint which can be connected to the push rods can be varied and fixed with respect to one another. <IMAGE>

Title: Method and system for mounting windings
Inventor: MUELLER FRANZ DIPL ING DR
IPC: H02K3/48
Filed: 1985-03-26
Abstract: In the event of transient processes in the machine, forces may arise which lead to the winding being loosened in the slots. The consequence of loosening is a mechanical and electrical destruction of the winding bar. The object of the invention is therefore to provide a method for mounting windings of electric machines in slots of laminated cores, with which the winding is mounted durably and reliably. According to the invention there is introduced into the slot (3) an electrically conductive, non-crosslinked polymer (4). The winding bar (1, 2) is embedded in this composition (4), the polymer (4) being replenished on that side of the bar which faces the opening of the slot. The winding is fixed until the polymer has cured. The main advantage is the possibility of economical manufacture. <IMAGE>
