Abstract
Abstract A mounting assembly for the deflection yoke of a three-gun, color cathode-ray tube including a carrier for the deflection yoke, a support mounted on the cathode-ray tube and means mounting the carrier on the support for longitudinal and pivotal movement. The position of the deflection yoke with respect to the tube is adjusted in three steps, (1) rotate the yoke about the tube neck to square the picture with the face of the tube, (2) position the carrier and yoke longitudinally on the tube neck for color purity, and (3) tilt the carrier and yoke to equalize scan width for all colors.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
An assembly for mounting a deflection yoke about the neck of a three-gun cathode-ray tube, comprising: a support on said cathode-ray tube; a carrier secured to said yoke; and means for mounting said carrier on said support for rectilinear movement in a direction substantially coincident with the longitudinal axis of the yoke and for pivotal movement about an axis perpendicular to said longitudinal axis, said mounting means comprising first and second studs on one of said carrier and support, disposed on said pivot axis, first and second slots in the other of said carrier and support receiving said first and second studs, and means cooperating with said studs releasably to restrain both rectilinear and pivotal movement between said carrier and support.
Claim 2
Dependent Claim
121 words
An assembly for mounting a deflection yoke about the neck of a three-gun cathode-ray tube, comprising: a support on said cathode-ray tube; a carrier secured to said yoke; and means for mounting said carrier on said support for rectilinear movement in a direction substantially coincident with the longitudinal axis of the yoke and for pivotal movement about an axis perpendicular to said longitudinal axis, said mounting means comprising first and second studs on one of said carrier and support, disposed on said pivot axis, first and second slots in the other of said carrier and support receiving said first and second studs, and means cooperating with said studs releasably to restrain both rectilinear and pivotal movement between said carrier and support.
Claim 3
Dependent Claim
28 words
The mounting assembly of claim 1 wherein the support is a closed frame structure having a plurality of legs adapted to contact the bulb of the cathode-ray tube.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1 wherein the yoke is rotatably mounted in said carrier to permit the relative rotation of the yoke about its longitudinal axis, said axis of rotation being substantially coincident with the longitudinal axis Of the neck of the cathode-ray tube when said mounting means is properly located on said cathode-ray tube.
