| Title | Letter from [Alan Archibald Campbell] Swinton, to The Editor, The Electrician |
| Creator | Swinton; Alan Archibald Campbell (1863-1930); British electrical engineer |
| Date | 27 May 1921 |
| Description | Informs that whilst listening to the Johnsen-Raheem Electrostatic Loud-Speaking Telephone and Relay, at the Institution of Electrical Engineers, he experienced a dim feeling of having had read of similar apparatus working on the same principle. Recalls Edison's loud-speaking telephone with its rotating cylinder of moistened chalk but also recollected that in effect of reducing the friction between the cylinder and the metallic slider rubbing thereon owing to electrolytic decomposition. Discusses further in detail, concluding that whilst nothing is new under the sun, the revival in an omproved and modified form of what would seem to be an old idea appears likely to have several useful present-day applications. |
