Abstract

799,167. Electric coils. PLESSEY CO., Ltd. Oct. 19, 1956 [Oct. 24, 1955], No. 30396/55. Class 35. [Also in Group XL (a)] A former unit for scanning coil assemblies comprises two sleeves 1 and 2 of rectangular cross-section, interconnected by a web 4 of material which when straight extends longitudinally of the sleeves, but may be bent to allow the coils to be threaded on a circular coil. The sleeves are provided with parallel end flanges 3 and 3a. The two coils may be wound simultaneously and then the structure, which may be moulded from a thermoplastic syntheticresin material such as polythene, is threaded on to a core 9 and clamped into position by means of a ridge 5 formed in the web. The starts 8 of the windings are received in slots in the flanges of the sleeves 1 and 2 and are insulated from the core by an extension 7 on sleeve 1 and the web.
