Abstract

404,395. Wireless receiving-apparatus. GRIMDITCH, W. H., Glensido, Pennsylvania, U.S.A. Aug. 23, 1932, No. 23579. Convention date. Dec. 19, 1931. [Class 40 (v).] In a wireless receiving-sot embodying a loud-speaker mounted behind a baffle, the receiver is located in an upper chamber 1 and the loud-speaker 4 and baffle 3 are in a lower chamber 2, the loud-speaker being arranged centrally of the baffle, which is tilted rearwardly. The axis of the sound-reproducing diaphragm is thus set at an angle to the horizontal, so that the sound is projected in an upwardly inclined direction. Reference has been directed by the Comptroller to Specification 312,031, [Class 40 (v), Wireless signalling &c.].
