Abstract

799,261. Moulds for making electric condensers. RADIO MATERIALS CORPORATION. Feb. 23, 1955 [April 5, 1954], No. 31587/56. Divided out of 799,260. Class 87(2). A gang mould for making a number of electric condensers simultaneously comprises a number of mould sections 18, Fig. 4, which are clamped together in a frame 19 by means of a screw 21. The contiguous faces of adjacent sections are hollowed out and co-operate to form moulding cavities 18a, Fig. 5, within each of which a central dielectric part 10 of a condenser is frictionally supported by means of terminals 11. The outer parts of the terminals are accommodated in grooves 18g in the mould sections, and terminal bosses 11b lie inside the cavities, spring tongues 11c holding the parts 10. Tongues and grooves 18c, 18d align the sections. Funnels 18b are formed in abutting mould sections for admission of liquid plastic material, which is poured into the cavities to form sheaths on parts 10 and unite the terminals to the latter. The sections are temporarily supported on an inclined base 24 for assembly purposes. Specification 799,262 is referred to.
