Abstract

282,702. Resonator, Ltd., (Assignees of Davis, C. H.). Dec. 29, 1926, [Convention date]. Diaphragms.- A conical diaphragm 3 of thin material such as wood veneer is wedged by a cord 4 in a groove in a ring 1 of cane, wood, vulcanite, celluloid, &c. into which the stylus holder 8 is directly screwed at a suitable angle. The diaphragm is preferably held on both sides by silk cords 4 glued in position except at the part adjacent the stylus. holder where cane wedges 6 are employed. The Specification as open to inspection under Sect. 91 (3) (a) states that the cord at one side of the diaphragm may be replaced by cane wedges. This subject-matter does not appear in the Specification as accepted.
