Abstract

450,472. Electromagnets. BOWMAN, W. J., 124, King Street, Kitchener, Ontario, Canada. Jan. 19, 1935, No. 1842. Convention date, April 20, 1934. [Class 35] [See also Group XL] The tuning condenser of a wireless receiver is driven by a solenoid comprising a core 22 co-operating with a plunger 23 working in fluid and incorporating a valve 24 which facilitates a dash-pot action when the plunger is attracted and a rapid upstroke when the solenoid is de-energized. The magnetic circuit is formed so that the force exerted is a linear function of the distance between the plunger and the core 22.
