Abstract

366,212. Adjusting wireless apparatus. COLE, Ltd., E. K., Priory Crescent, Southend-on-Sea, and WYBORN, E. J., Hedgerows, Ardleigh Green Road, Hornchurch, Essex. Dec. 12, 1930, No. 37586. [Class 37.] A multi-range tuning adjustment for wireless apparatus has a pointer moved over a dial in the form of an annular band of large radius compared with the radius of the condenser plates, the dial embracing a complete circumference. As shown, the scales 1, 2 are illuminated by lamps 12, 13 connected in circuit by a contact 9 operated by a cam 7 on the condenser spindle 6 which is geared to an indicating pointer 3. The scales may be transparent or translucent and may be illuminated by reflected light, or the scales may be continuously illuminated and an arrow on each dial may be illuminated to indicate the scale in use. The scale not in use may be masked.
