Abstract

1343233 Selective printing NIXDORF COMPUTER AG 20 April 1972 [21 April 1971] 18335/72 Heading B6F [Also in Division H1] Each wire 5 in a wire mosaic printer is actuated by an electromagnet comprising a coil 1 formed on two magnetic pole members 2, 3, the wire being fixed to an armature 4, the poles 2, 3, being separated by a magnetically non-conductive electrically conductive ring 8 to act as an eddy current generator. The armature moves between stop members 7, 12 both of which are adjustable, the stop 7 being formed of impact damping material. A spring 6 biases the armature away from rest position. The ring 8 may be of copper.
