Abstract
Abstract A color television display system handling and adjustment apparatus provides a means for maintaining accurate alignment between the base of a kinescope and an energization socket. The kinescope location within the apparatus is referenced to the kinescope front panel contour so that transverse movement of the kinescope does not cause significant movement of the kinescope base. The apparatus also provides means for simulating convergence adjustment of yokes constructed for front and rear tilt convergence adjustment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
An apparatus for positioning a deflection yoke on the neck of a color television kinescope to converge a plurality of electron beams on the face of said kinescope, comprising: a yoke holder coupled to one end of said yoke, said yoke holder comprising a rigid member and a flexible member disposed between said rigid member and said yoke; and means for moving said yoke holder in a direction transverse with respect to said kinescope neck through a first distance in which both ends of said yoke are free to move with respect to said kinescope neck and in the same transverse direction through a second distance such that the end of said yoke remote from said yoke holder contacts said kinescope at a contact point, causing said yoke to pivot about said contact point, movement of said yoke through said first and second distances converging said beams from a first and second misconverged condition, respectively, said pivoting of said yoke causing the shape of said yoke holder flexible member to distort in order to maintain said yoke holder rigid member in orthogonal alignment with respect to said kinescope neck.
Claim 2
Independent Claim
189 words
An apparatus for positioning a deflection yoke on the neck of a color television kinescope to converge a plurality of electron beams on the face of said kinescope, comprising: a yoke holder coupled to one end of said yoke, said yoke holder comprising a rigid member and a flexible member disposed between said rigid member and said yoke; and means for moving said yoke holder in a direction transverse with respect to said kinescope neck through a first distance in which both ends of said yoke are free to move with respect to said kinescope neck and in the same transverse direction through a second distance such that the end of said yoke remote from said yoke holder contacts said kinescope at a contact point, causing said yoke to pivot about said contact point, movement of said yoke through said first and second distances converging said beams from a first and second misconverged condition, respectively, said pivoting of said yoke causing the shape of said yoke holder flexible member to distort in order to maintain said yoke holder rigid member in orthogonal alignment with respect to said kinescope neck.
Claim 3
Dependent Claim
23 words
The arrangement defined in claim 1, wherein said yoke moving means moves said yoke along the horizontal and vertical axis of said kinescope.
Claim 4
Dependent Claim
22 words
The arrangement defined in claim 1, wherein said yoke holder flexible member comprises an elastic ring encircling one end of said yoke.
Claim 5
Independent Claim
187 words
A method for positioning a deflection yoke on the neck of a color television kinescope to converge a plurality of electron beams on the face of said kinescope, comprising the steps of: coupling one end of said yoke to a yoke holder comprising a rigid member and a flexible member disposed between said rigid member and said yoke; moving said yoke holder in a direction transverse with respect to said kinescope neck in which both ends of said yoke are free to move with respect to said kinescope neck in order to converge said beams from a first misconverged condition; and moving said yoke holder in the same transverse direction through a sufficient distance such that the end of said yoke remove from said yoke holder contacts said kinescope at a contact point, causing said yoke to pivot about said contact point, in order to converge said beams from a second misconverged condition, said pivoting of said yoke causing the shape of said yoke holder flexible member to distort in order to maintain said yoke holder rigid member in orthogonal alignment with respect to said kinescope neck.
Claim 6
Independent Claim
187 words
A method for positioning a deflection yoke on the neck of a color television kinescope to converge a plurality of electron beams on the face of said kinescope, comprising the steps of: coupling one end of said yoke to a yoke holder comprising a rigid member and a flexible member disposed between said rigid member and said yoke; moving said yoke holder in a direction transverse with respect to said kinescope neck in which both ends of said yoke are free to move with respect to said kinescope neck in order to converge said beams from a first misconverged condition; and moving said yoke holder in the same transverse direction through a sufficient distance such that the end of said yoke remove from said yoke holder contacts said kinescope at a contact point, causing said yoke to pivot about said contact point, in order to converge said beams from a second misconverged condition, said pivoting of said yoke causing the shape of said yoke holder flexible member to distort in order to maintain said yoke holder rigid member in orthogonal alignment with respect to said kinescope neck.
