Abstract

1,191,398. Selective signalling. EICHNER ORGANISATION G.m.b.H. 19 Feb., 1968 [11 March, 1967], No. 7924/68. Heading G4H. Operation of the type levers of an electrictypewriter is controlled by a circuit comprising a plurality of function-supervisory circuits, at least one of which prevents operation of a further type lever until operation of a previously actuated lever has been completed. The circuit also causes repeated operation of a type lever if the initial strike attempt is not completed in a predetermined time.
