Abstract

366,888. Recording and reproducing sound magnetically. STILLE INVENTIONS, Ltd., 35, Little Newport Street, London. Oct. 15, 1931, No. 28686. Convention date, Oct. 15, 1930. [Class 40 (ii).] In machines employing a magnetic band or wire record this is driven by frictional contact with a uniformly driven drum at the minimum speed suitable for reproduction, and the record is taken up on a spool which is driven frictionally and slips as the record wound thereon increases. The record L passing from a spool T<1> and around a constantly driven drum A to a take-up drum T<2> driven frictionally by a roll R is guided by rolls S<1>, S<2> positioned so that the record embraces more than 180‹ of the drum A.
