Abstract

732,231. Impulse transmitters. LEVISON, L. March 3, 1954 [Feb. 22, 1952], No. 4784/52. Class 40 (4). An indicator attachment for a dial-type transmitter comprises an annular member 15 formed with a collar 12 which fits closely over the base of the dial and is notched at 13 to fit the finger stop. The attachment may be made of metal, cellulose or polystyrene and is stiffened by a peripheral flange 18. The inscription may be applied by silk screen printing or may be inlaid in plastic. Luminous paint may be used. The member 15 may be cut away at A and B so that it can be fitted to a telephone set with a concave front. According to the Provisional Specification the annular member may be a trough-like casing enclosing electric lamps. The inscriptions are then formed by translucent portions of an opaque lid on the trough.
