Abstract

1,241,667. Selective printing. KOMBINAT ZENTRONIK VEB. 11 Nov., 1968, No. 53397/68. Heading B6F. Means for checking that a print hammer 6 has carried out an impression movement comprises a piezo-electric transmitter 11 which generates an electrical pulse whenever the hammer returns to its rest position. The transmitter is made in the form of a piezoceramic cylinder supported between a screw 17 and an electrically conductive abutment 14. The pulse may be taken from the abutment 14 and the screw 17 as shown, the screw being let into an insulating plate 18, or the cylinder 11 may be supported between two conductive discs from which the electrical pulse is taken. The hammer 6 may be operated by an electromagnet (1), Fig. 1, not shown, and returned by a spring (3), a permanent magnet (9) being provided to prevent rebound, and may co-operate with a type drum (7).
