Abstract
1440787 Cathode-ray tubes INTERNATIONAL STANDARD ELECTRIC CORP 14 Sept 1973 [2 Oct 1972] 43281/73 Heading H1D An adjustable mounting arrangement for a toroidal deflection coil of a cathode-ray tube, particularly a colour television tube, includes a basket 10 mounted around the tube and fixed thereto by feet 11, and a housing 30, Fig. 1b (and Fig. 3, not shown) to which the coil is fixed, a ring 20 being held between the basket and the coil housing by the resilient hooked portions 12 formed on the basket. The ring 20 has on its outer surface a screw thread 21 with which guide elements 31, Fig. 1b, or 311 and 312, Fig. 1a, formed on the coil housing engage, stops preventing rotation of the latter, whereby rotation of the ring, which may be provided with projections at the ends of the thread to constitute handles, produces axial movement of the coil housing.
