Abstract
Abstract An electron beam influencing apparatus comprises a deflection yoke which incorporates a kinescope neck-embracing collar which extends from the rear of the yoke. The collar extends over a portion of a slidably mounted sleeve. Permanent magnet neck components are rotationally mounted to the sliding sleeve. The collar and sleeve are formed so that the yoke and collar rotates independently of the sleeve, but longitudinal movement of the yoke and collar will cause longitudinal movement of the sleeve also. A single clamp is used to secure the collar and sleeve to the tube neck. The collar may be attached to a yoke adjustment plate which allows pivotal or transverse yoke motion while maintaining stationary positioning of the adjustment plate.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
In combination with a color kinescope having a neck and a funnel portion, an electron beam influencing apparatus comprising: a yoke support secured to said funnel portion of said kinescope; a deflection yoke having a front end received by said yoke support in a manner permitting pivotal, rotational and longitudinal motion of said yoke; a flexible mounting sleeve slidably disposed along said kinescope neck; an annular magnetic beam convergence structure secured to said sleeve; a flexible yoke mounting collar mounted to the back of said yoke; said collar embracing a portion of said sleeve in a manner allowing independent rotational movement of said collar with respect to said sleeve while assuring dependent movement of said sleeve in response to longitudinal movement of said yoke along said kinescope neck; and a clamp, disposed about said collar, for selectively fixing the positions of said yoke and said beam convergence structure on said kinescope neck.
Claim 2
Dependent Claim
152 words
In combination with a color kinescope having a neck and a funnel portion, an electron beam influencing apparatus comprising: a yoke support secured to said funnel portion of said kinescope; a deflection yoke having a front end received by said yoke support in a manner permitting pivotal, rotational and longitudinal motion of said yoke; a flexible mounting sleeve slidably disposed along said kinescope neck; an annular magnetic beam convergence structure secured to said sleeve; a flexible yoke mounting collar mounted to the back of said yoke; said collar embracing a portion of said sleeve in a manner allowing independent rotational movement of said collar with respect to said sleeve while assuring dependent movement of said sleeve in response to longitudinal movement of said yoke along said kinescope neck; and a clamp, disposed about said collar, for selectively fixing the positions of said yoke and said beam convergence structure on said kinescope neck.
Claim 3
Dependent Claim
20 words
The beam influencing apparatus defined in claim 1, wherein said beam convergence structure comprises a plurality of beam bender magnets.
Claim 4
Dependent Claim
46 words
The beam influencing apparatus defined in claim 1, wherein said yoke mounting collar is formed as a portion of a yoke adjustment plate, said plate releasably mounted to the back of said yoke for allowing pivotal movement of said yoke with respect to said kinescope neck.
