    Abstract: Deflection ring of sintered MgZn-ferrite material, cathode ray tube comprising such a ring and moulding made from this material. The invention relates to a deflection ring of sintered MgZn-ferrite material. In accordance with the invention, this deflection ring is characterized in that the majority of the grains of the sintered material have a monodomain structure. By virtue thereof, a relatively small heat dissipation occurs in the ring when it is used in a cathode ray tube. The average grain size of the sintered MgZn-ferrite material is preferably 2.8 micrometers or less. MgZn-ferrite materials whose composition corresponds to the formula Mg.sub.1-z Zn.sub.z Fe.sub.2-y O.sub.4, wherein 0.1

    Abstract: Method of manufacturing a deflection unit comprising a set of diametrical deflection coils, in which method the coils are placed on a jig which supports each coil at a plurality of locations and in which a coil support of synethic material is urged against the free surface of each coil. The coils are mechanically anchored by means of, for example an ultrasonic welding process in which the locations of the coil support situated opposite supported locations of the coils are softened and pressed into the coils. The coils are not deformed in that case and their mutual position defined by the jig is accurately maintained.

    Abstract: A deflection unit for a color television display tube comprising line and frame deflection coils and a magnet core cooperating with said coils can be manufactured by placing the deflection coils and the magnet core around the part of the transition neck-cone of a color display tube in such manner that the deflection coils engage or substantially engage the tube, which display tube comprises an adjusted color purity magnet, after which the tube is adjusted so as to be color pure by moving the magnet core along the axis of the tube, after which, if desired, the magnet core is moved in known manner in a plane perpendicular to the tube axis so as to remove convergence errors and the magnet core and the coils are then connected together to form the deflection unit.

    Abstract: A coil winding machine winds a wire about a core to form, for example, one-half of a television deflection coil. The wire is spun about the core by a flyer arm which is rotated about an axis and guides the wire over a series of pulleys rotatably mounted thereon. The wire is pulled through the bore of a tubular shaft, which carries the flyer arm, which shaft is driven rotatably and reciprocally along its axis. The core is removably held in a clamp which is fixed to a tool holder having gear teeth, preferably a sector of a worm gear. The tool holder is driven to obtain a rocking motion during the winding operation by a worm mounted on a drive shaft. That drive shaft is rotatably held in the cross-member of a cradle assembly which cradle assembly is pivotally mounted on the base and rocked back and forth during the winding operation.

    Abstract: During the winding of coils with a non-circular shape the wire length necessary varies periodically for a trouble-free winding per unit of time. At a high winding rotational speed and unsatisfactory side ratios relative to the coil being wound, the periodic change in the required wire length is so large that with known wire brakes there is no adequate winding quality with a concurrent protective handling of the wire. These opposite goals are reached through the invention with the aid of a controllable wire brake which essentially consists of a plurality of brake strands wound about the wire in a single layer.
