Abstract

1,006,834. Feeding elongate records; backspacing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 20, 1961 [Dec. 23, 1960], No. 45617/61. Heading G5R. A tape or wire dictating machine has operating keys 3, Fig. 1, lockable by a common pawl 18, which pawl is retracted by an electromagnet 19, Fig. 2, operated either by record stop-foils 32, Fig. 3, or by a switch 35 on the remote handset bridging the foil contacts. While the foils only make a temporary circuit to halt the record, extended operation of the switch 35 causes the electromagnet 19 to engage a pulley 27 with the capstan flywheel 25 to drive the feed reel support 24 for back-spacing.
