Patent DE-3006228-A1 (DE)
Inventor: PERLE JOSEF ING GRAD
IPC: H01H3/30
Filed: 1980-02-20
Abstract: The device is used for blocking and releasing a switching shaft (10), which can be operated via a force store, of a load interruptor switch. In the case of the device, the switching-shaft movement is blocked or released by means of two identically constructed toggle-lever arrangements (14-17), which are connected to the switching shaft (10) via a common arm (12), via a release shaft (18) which interacts alternately with one of the two toggle-lever arrangements. Since that toggle-lever arrangement which is in each case latched is located close to the extended position, that is to say shortly in front of the dead-centre position, only very small forces occur between the latching stop (19, 20) and the release shaft (18) so that it is possible for this release shaft to pivot and the latching thus to be released virtually independently of the forces which act on the release shaft via the toggle-lever arrangement. <IMAGE>

Patent DE-3017426-A1 (DE)
Title: Ultrasonic head for welding armature wires to segments of collector - has peripheral recesses which mate with each segment as components are rotated in mesh with reciprocating action of electrode
Inventor: NIEBUHR FRED ING GRAD
IPC: H01R43/02
Filed: 1980-05-07
Abstract: To connect an insulated armature winding wire (12) with the armature segment (14) and ensure a conductive connection, a loop is usually placed over a hook (18), which is then folded back. The connection, in this case, is made using ultra-sonic welding techniques and a specially shaped electrode, in contact with the collector (10). This electrode (sonotrode) is cylindrical (22), and has a number of recesses (24) spaced at regular intervals around its periphery, so formed, that when in contact with the collector (10), the segments (14) mate with these recesses as the two components (22,16) are rotated, (in a similar manner to a pair of gears in mesh). The hooks (18) are thus under a high pressure, when the segments and recesses fall on a common centre line as they revolve, the welding taking place at this position. The electrode, (sonotrode) (22), oscillates backwards and forwards as well as rotating, and apart from stripping the insulation from the wire (18), forms a solid electrical connection free from local hardening and thus hot spots, which cause armature breakdown.

Patent DE-3044075-A1 (DE)
Inventor: DREWS DIETER DIPL ING
IPC: B23Q35/12
Filed: 1980-11-24
Abstract: In order to increase the capacity of generation grinding machines and improve the quality of the ground gears, approximately the same maximum values for the cutting force or supporting force, relative to a stroke of the grinding body, are guaranteed during the grinding of a tooth flank from the root of the tooth to the top of the tooth. This is achieved by the maximum value, occurring during a stroke, for the cutting force or supporting force being recorded and stored. An average is formed from the stored values of two successive strokes. This average is compared with a preset desired value. The result of the comparison is used in such a way to control the speed of the generating movement. The maximum value occurring during the next stroke lies close to the desired value, a likewise preset limit value for the speed of the generating movement not being exceeded. <IMAGE>
