Abstract

496,384. Fluid-pressure servomotorcontrol systems. OELSNER, W. March 25, 1937, Nos. 8922 and 8923. Convention dates, March 26, 1936 and March 20, 1937. [Class 135] [Also in Group XXXVIII] In an arrangement for varying the tension applied to vibratory plates p, mounted adjacent the boundary surfaces of a room, in accordance with sound pressure prevailing in the room and having separate controlling means according to the frequency range of the sound, the high frequency components pass through a filter T and an amplifier B to energize a relay p controlling a motor q which operates a three-way valve u connected between a source z of fluid pressure and pipes leading to opposite ends of a cylinder w in which is enclosed a piston v attached to one of the plates p.
