Abstract

566,703. Variable condensers. MULLARD RADIO VALVE CO., Ltd., and MAITLAND, C. E. July 1, 1943, No. 10714. [Class 37] A plate of a variable condenser has a series of frangible members around its edge to permit of exact capacity matching. In the example, a series of holes 3 and narrower slots 5 give rise to lines of incipient fracture 4, at which small parts 6 may be broken off.
