Abstract

304,165. Braendle, E. W., and Billingsley, R. H. Oct. 12, 1927. System modified for use in condenser telephones.-A movable electrode 1 associated electrostatically with two or more fixed electrodes 6, 7, is connected to the grid 2 of a valve in such a way that the grid is free or insulated, as described in Specification. 276,479, [Class 40 (v), Wireless signalling &c.]. Movement of the electrodes 1 in response to mechanical acoustical or like impulses, causes variations to the plate current which may be applied to amplifying or reproducing apparatus.
