Abstract
340,705. Sound records. BERGER, A., 10, Holdershill Avenue, Hendon, London. Nov. 8, 1929, No. 34204. [Class 40 (ii).] A sound record for use in electromagnetic recording or reproducing apparatus consists of a flexible sheet or strip of fabric, paper, celluloid, rubber or like material provided on one or both faces with a permanent and evenly distributed layer or coating of comminuted metal which is capable of being permanently magnetized. The metal may consist of one or more of the following :- stainless steel, iron, iron or steel alloy; or may consist of iron or steel or a mixture of iron and steel together with nickel or cobalt or a mixture of nickel and cobalt. The metal may be dusted on to a coating of liquid glue or other adhesive applied to the flexible sheet and the coated sheet may then be rolled. In another form, the metal may be sprayed on to the sheet, liquid glue being added to the metal if desired. A groundwork of tin or other material may be sprayed on to the sheet prior to the spraying of the magnetizable metal. A non-corrosive coating such as aluminium may be provided on the coated sheet. Specifications 324,099 and 333,154, [both in Class 40 (ii), Phonographs &c.], are referred to. Reference has been directed by the Comptroller to Specification 8961/99, [Class 40, Electric telegraphs &c.].
