Abstract
512,765. Recording sound and other oscillations. LEOPOLDIN GES. Nov. 29, 1937, No. 32961. Void. Convention date, Nov. 27, 1936. [Class 40 (ii)] In a method of recording sound and other oscillations, the record material is passed through a high-frequency field. In one method currents from a microphone 1, amplified at 2, modulate a high-frequency generator 3, the output of which produces a modulated H.F. field between the plates 10, 11 of a condenser between which the sensitive material is passed, as on a film. The plate 16 is pointed to produce concentration of the field of the recording point. In modifications (1) an unmodulated H.F. field is used and one electrode is moved by the speech currents either transversely (Fig. 5 not shown) or in such a manner that its distance from the film varies (Fig. 6 not shown).
