    Abstract: 1,261,226. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 13 May, 1969 [14 May, 1968], No. 24319/69. Heading B6F. Type elements 3 are attached to an endless band, 1 having teeth on its inner surface by side limbs which engage the sides of the belt and pins (10, Figs. 2, 3) which engage holes or grooves in the teeth on the belt and holes on the side limbs of the type elements. The pins permit the type elements to pivot as they meet a guide 4 so that they are aligned parallel with the back 5 of the guide 4 without tensioning the belt 1. Grooves (11, Fig. 3) in the teeth permit movement of the type elements towards and away from the outer face of the belt.

    Abstract: The striker type printer has type carriers revolving crossways to the feed direction of the printing cloth which has a roller on which it is wound or unwound. The cloth (4) is guided over one or more pivotable rollers (1) swivelling around a rotary point between two stops (11,12). The pivotable roller is so arranged that its axis runs parallel to the direction of rotation of the type carrier, and its free pivot end also points in that direction. The roller (11), by contact with the printing cloth (4), swivels in the direction of the cloth feed as far as one of the stops. In order to compersate a lateral displacement (LS) of the cloth caused by the printing process in the rotary direction of the type carrier, by rotation of the pivot roller a force component is exerted on the printing cloth.

    Abstract: Arrangement for a print head having at least one print electrode and being movable relative to a record carrier transported over a support, and pressed down onto the record carrier by the effect of an actuator, where a first frame piece (4) carrying the print electrode (6) supported in a holder (5) is pivotably fixed, via a spring arrangement (2,3) biasing the print head towards the record carrier, to a second frame piece (1) opposite the first frame piece (4), where furthermore an electromagnetic actuator (9, 10) between the two frame pieces is attached to the second frame piece (1) to which a resilient ferromagnetic armature (14) is also fixed and through its greater bias acting against the bias of the spring arrangement (2, 3) abuts against a non-ferromagnetic stop (15) provided at the first frame piece and facing the end of the armature, which thus lifts the print head against the force of the spring arrangement (2, 3), and where by the operation of the actuator (9, 10), the print electrode ( 6) places itself against the record carrier (7) under the force of the spring arrangement (2, 3).
