Abstract

471,796. Wireless receiving-apparatus. DREYFUS, J. A. Dec. 6, 1935, No. 33857. Convention date, Dec. 6, 1934. [Class 40 (v)] [Also in Group XXXVI] The dial 3 of a radio receiver is of translucent material impervious to sound and is located behind a fabric screen 12 which appears opaque when the intensity of light outside the casing is greater than that inside the casing but through which the scale can be seen when a lamp 7 inside the set is energized. The loudspeaker 2 may be located behind an extended portion of the same fabric 12 or it may have an entirely independent aperture. A reflector may be provided behind the lamp 7. Specification 438,631 is referred to. The Specification as open to inspection under Sect. 91 describes an arrangement in which a clock face is marked on the fabric screen so as to be visible under all conditions and cooperates with a clock mechanism and hands, which latter are of transparent celluloid. Materials suitable as' fabric screens were also specified. This subject-matter does not appear in the Specification as accepted.
