Abstract: PCT No. PCT/EP85/00160 Sec. 371 Date Dec. 5, 1985 Sec. 102(e) Date Dec. 5, 1985 PCT Filed Apr. 9, 1985 PCT Pub. No. WO85/04548 PCT Pub. Date Oct. 24, 1985.In a cutting head for an electric-motor-driven filament-type cutter the automatic adjustment of the length of the filament is effected in that intermittently a rotational movement occurs between a filament spool (36) and a sleeve (24) mounting said spool for axial displacement. The sleeve (24) is provided on the outside with locking cams and the filament spool on the inside with cams cooperating therewith. The sleeve (24) can be pushed in by hand against spring pressure to cancel the intermittent locking. For automatic filament adjustment a centrifugal adjustment is provided. For this purpose at least two radial ball slots (40) are provided between the housing portion (14) and a radial extension (48) of the sleeve (24) and in the ball slots balls (44) are guided which are adapted to be urged outwardly by centrifugal force. Since the height of the ball slot varies over an inclined plane (42), when the balls (44) move radially outwardly a spreading of the two parts (48, 14) takes place so that intermittent unlocking results. The individual rotational angle portions are limited by lower and upper cams which cooperate with a counter cam which is controlled by the displacement movement and cooperates alternately with the one or other cam, the sectionwise or intermittent angular displacement taking place by repeated switching on and off of the motor.
Patent DE-3417362-A1 (DE)
Title: Process for soldering wire portions to workpieces, and apparatus for carrying out the process
Inventor: PUTZ WILHELM
IPC: B23K3/06
Filed: 1984-05-10
Abstract: The soldering of wire portions to workpieces is often difficult, for example when solder and flux are to be supplied at locations of difficult access and the connection between the wire end and the workpiece is simultaneously to be made by means of a tool by heating. According to the invention, the wire portion is provided with a suitable quantity of solder in a pretreatment phase, and the soldering takes place subsequently. In the associated apparatus, a soldering station is composed of individual workstations, in which cut-to-length or bared wire portions are introduced and brought into the soldering position (I); subsequently, an individual wire portion is fixed axially and the heated soldering wire is pushed onto the wire end and cut off (II); then, the wire portion, including the attached piece of solder, is blown out, the flux of the adhering piece of solder likewise being cooled (III). This results in an automated work operation for soldering the wire ends, which can thereafter be soldered at the desired location on the workpiece with the smallest possible tools (soldering iron). <IMAGE>

Patent DE-3422958-A1 (DE)
Title: Vacuum switch
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/14
Filed: 1984-06-19
Abstract: For the reliable and economical control of even relatively high rated voltages using vacuum switches, two cooperating pairs of stationary (5, 6) and movable (3, 4) switching contacts form two switching spaces (15, 16) in an evacuated switching vessel (A). The stationary switching contacts have both a contact body and a winding former of particularly low structural height. In this case, the winding formers are connected in series in the same winding direction and, when current is passing through them, produce a magnetic field parallel to the longitudinal axis of the switching housing. As a result of this arrangement and the structural shape of the stationary switching contacts, the movable switching contacts do not need to be provided with winding formers. Electrical control resistors can advantageously be used for the uniform distribution of the voltage on the switching housing over the two switching spaces. <IMAGE>
