Abstract:
A deflection coil is formed into a saddle shape by winding up a conductive wire ribbon in layers, such that the layered wire ribbon is formed in its cross-section into a parallelogram with adjoining sides crossing one another at other than 90 degrees. The deflection coil is produced by winding up in layers the wire ribbon in a plurality of coil grooves of a coil-winding frame die while the wire ribbon is delivered out from a nozzle, obliquely against the side wall face of each coil groove.
Abstract:
An apparatus for winding saddle shaped coils particularly useful as deflection coils for cathode ray tubes. The apparatus can handle single or multiple strands of wire depending upon the coil design, and includes a winding pattern generator (26) connected to a winding head (28) which feeds the wire into a suitably configured mould. The winding pattern generator directs the winding head in sequential arcuate and longitudinal directions and does not stretch the wire as turns are made in the coil. This stretching or "necking down" of the wire, which occurred in prior art machines of the lathe type, caused varying electrical characteristics in the coils which presented a problem to the ultimate users.
Abstract:
An apparatus for slant winding of toroidal deflection coils. A first wire guide is pivotally mounted at the area of the end face of the core having the smaller diameter. A second wire guide, arranged on an annular plate rotatable about the same axis as the core, at the area of the end face of the core having the larger diameter is formed by two wire interceptors which laterally fan out from the core edge such that one of the wire interceptors always intersects the plane of the winding wheel.
Abstract:
A machine for winding toroidal coils useful as picture tube beam deflection yokes in television recievers includes a coil winding shuttle, a filament storage magazine and structure for selectively varying the angular rate of rotation of the shuttle during the winding of each turn of the coil so as to maintain the feed rate of the filament from the magazine to the shuttle at a substantially constant rate. Additionally, a double chamber magazine and a double acting clamp are provided which respectively permit winding of the entire yoke with two separate coils and winding each coil without displacing the yoke from its winding position.
Abstract:
Projecting points on a yoke core are utilized to permit the winding of a number of separate and distinct coils as a single coil capable of subsequent separation into said separate coils. After the winding of a first coil the wire is snubbed against a first of such projecting points and the winding operation is stopped. The yoke core, however, is continuously rotated, dragging the wire across the yoke core until a second projecting point is reached, at which time the winding of a second coil is commenced.
Abstract:
The active field producing conductor turns on the inside generally cylindrical core surface of a multilayer toroidal deflection yoke are wound in one direction, e.g., clockwise. The return conductors on the outside of the core are wound in a flyback manner for enabling conductors to be placed in a second layer between the conductors of the first layer for forming a higher conductor distribution density for a first coil or for interleaving the conductors of a second coil between the conductors of the first coil. The two layers may thus be wound over a large angular portion of the core without stopping the winding machine for the cutting or tying of conductors within each coil.
Abstract:
A printed circuit steering coil on a flexible board for producing a charged particle beam deflecting magnetic field wherein rectangular, continuous planar spiral coils are etched on the circuit board opposite sides such that as each of at least two boards are bent into cylindrical shapes and disposed interiorly in a steel tube of high permeability permitting beam passage, the coils provide for individual horizontal and vertical steering of the charged particles.
Abstract:
A coil assembly includes a coil form and a winding. The coil form includes a base defining a loop defined by a pair of opposed first sides and a pair of opposed second sides, a plurality of spaced apart support members extending from the base along the first sides, and a coil support structure extending from the base at each of the second sides. Each support member includes a first portion and a second portion, the first portion extending from the base and the second portion extending from the first portion, with a gap is defined between adjacent support members. The winding abuts the first portion of at least some of the spaced apart support members and is at least partially secured by the second portions of the support members. The winding abuts each of the coil support structures, and is curved in a saddle shape.
Abstract:
A three-phase, multi-winding includes a core, the core including a hub and an outer shell around a perimeter of the hub. wherein the hub and the outer shell are in a fixed position with respect to each other. The core also includes multiple slots. In addition to the core, the multi-winding device includes a primary winding positioned in at least two of the slots; and multiple spatially distributed secondary windings, wherein at least one of the secondary windings is positioned proximate the primary winding in at least one of the two slots.
