Abstract

771,066. Electric coils. VISSEAUX SOC. ANON., J. July 12, 1954 [July 10, 1953], No. 20383/54. Class 35. [Also in Group XL (a)] Each coil of a cathode-ray tube deflecting system has turns shaped as in Fig. 4 when developed in flat form. A printed coil 2, Fig. 5, is folded about the line 3 to form the coil 4, Fig. 6. Four coils on a common backing are bent around the tube neck to form a complete system. Several coils may be piled together and connected in series before or after they are folded. Each coil is made by gluing a conducting foil on an insulating sheet, photographically printing on the foil a picture of the coil, and after developing and washing, etching away unprotected areas.
