Abstract

764,691. Gramophone records. POOLE, R. M. March 1, 1955 [Dec. 4, 1953], No. 33714/53. Class 40 (2). A record disc has in the central unrecorded portion, or other convenient part, of each side, a ring of electrically conducting material whose diameter is of a standardized diameter for an individual speed group but varying in diameter in respect of each speed group. Information as to the speed group to which a record belongs is transmitted to a record changing mechanism by means of a brief automatic application of circuit selecting contacts to the record whereby the characteristics of the mechanism may be altered to those appropriate to the nature of the record to be played.
