Abstract
560,372. Adjusting condensers. MULLARD RADIO VALVE Co., Ltd., VINALL, C. W., BARRY, W. C., and MAITLAND, C. E. Dec. 2, 1942, No. 17156. [Class 37] An electric condenser comprises a ceramic tube 1 carrying a fixed electrode 2 which co-operates with an adju stable electrode 5 carried on a rod 6 having screw-threaded engagement with a unit 8 in the form of a coil of wire which closely embraces the end of the ceramic tube 1 and has a free end 9 for electrical connection. The element is dipped in a solder bath to solidify coil 8, the rod 6 being treated to prevent adhesion of the solder. A supporting member 10 surrounds nut 8 to which it is soldered, and carries an arm 12 having a claw-like end for engaging the screw-thread on rod 6 to give good electrical connection. A second connection member 3 surrounds the fixed electrode 2 to which it is soldered. In a modification, the fixed electrode is formed of a coil of wire surrounding the tube 1.
