| Title | Letter from [Alan Archibald Campbell] Swinton, to Professor [John Ambrose] Fleming |
| Creator | Swinton; Alan Archibald Campbell (1863-1930); British electrical engineer |
| Date | 2 May 1927 |
| Description | Sends a copy of his paper on Television, which contains allusions to his letter to Nature on the subject, in 1908, and his address to the Rontgen Society in 1911. States that he has since thought of many improvements, such as the employment of running machinery for producing the two electric currents of widely different frequencies, for controlling the cathode rays at each end, might be rendered unnecessary by the use of Fleming's valves made to oscillate at suitable frequencies. Informs that Zworykin, of the American Westinghouse Company, has patented the use of three-colour screens at both ends, in an apparatus almost exactly the same as he sketched out, so as to have Television in colour. Informs he has written to the photographer who usually photographs Orpen's portraits, and asked him to photograph Fleming's portrait. |
