Abstract

289,663. Etablissements E. Belin, and Belin, E. June 11, 1927. Addition to 272,250. Optical and photographic recorders.-The system described in the parent Specification yields at the receiving station a photographic morse record on a tape. This may be transcribed into written characters by passing it through electrooptical apparatus controlling a Creed printer. The recorder operates at a higher speed than the printer, however, and the record tape is therefore received and stored on a drum. It is subsequently drawn from this and passed through one of several simultaneously operating translating apparatus. In order that the operator may be able to see whether signals are being satisfactorily received. the recorder is shunted by a cathode ray oscillograph.
