Abstract
Abstract Improved means for mounting a cathode-ray tube deflection yoke, wherein means are provided for achieving three-dimensional adjustment of the yoke relative to the long axes of both the tube neck portion and the yoke housing. A clamp is provided which engages the yoke and has a pair of diametrically opposing arms that are respectively received in a pair of diametrically opposing axially extending slots provided in the yoke housing to thus support the yoke therein. Fastener means are provided which can be inserted through each of the yoke housing slots and also through additional slots provided in the clamp arms and extending substantially orthogonally to the yoke long axis, whereby the yoke may be secured in a wide range of positions relative to the long axes of its housing and the tube neck portion.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
Improved mounting means for a deflection yoke of a cathode ray tube comprising: a. housing means enclosing the yoke and including means for supporting said housing on the cathode ray tube; b. adjustable means connected to and supporting the yoke within said housing, c. said adjustable means and housing means having intersecting slots defining substantially mutually orthogonal guiding surfaces permitting displacement of any point on the yoke through more than one plane with respect to said housing; and d. fastener means extending through said slots at the intersection thereof, said fastener means being adapted to prevent relative movement between said adjustable means and said housing means.
Claim 2
Dependent Claim
106 words
Improved mounting means for a deflection yoke of a cathode ray tube comprising: a. housing means enclosing the yoke and including means for supporting said housing on the cathode ray tube; b. adjustable means connected to and supporting the yoke within said housing, c. said adjustable means and housing means having intersecting slots defining substantially mutually orthogonal guiding surfaces permitting displacement of any point on the yoke through more than one plane with respect to said housing; and d. fastener means extending through said slots at the intersection thereof, said fastener means being adapted to prevent relative movement between said adjustable means and said housing means.
Claim 3
Dependent Claim
47 words
The invention of claim 1, wherein said adjustable means permits displacement of said point with respect to said housing means in a first group of planes orthogonal to and in a second group of planes parallel to the long axis of the cathode ray tube neck portion.
Claim 4
Dependent Claim
25 words
The invention of claim 2, wherein said adjustable means permits rotational displacement of said point about said axis and in said first group of planes.
Claim 5
Dependent Claim
32 words
The invention of claim 3 wherein said adjustable means further includes an arm extending through an aperture in said shell and serving as a handle for rotating said yoke about said axis.
Claim 6
Dependent Claim
25 words
The invention of claim 3, wherein said adjustable means permits linear displacement of said point along said axis and in said second group of planes.
Claim 7
Dependent Claim
21 words
The invention of claim 5, wherein said adjustable means permits arcuate displacement of said point in said second group of planes.
Claim 8
Dependent Claim
170 words
An improved adjustable deflection yoke assembly for a cathode ray tube having a funnel portion and a neck portion, said assembly comprising: a. a yoke encircling the tube neck portion; b. housing means including a shell enclosing said yoke and further including front and rear means for engaging the cathode ray tube at the funnel portion and the neck portion respectively; c. said housing means having a first slot defined by a first pair of opposing substantially parallel surfaces; d. adjustable Means secured to said yoke, e. fastener means extending through said first and said second slots at the intersection thereof, said fastener means being adapted to prevent relative movement between said ajdustable means and said housing means; f. said first and second pairs of opposing substantially parallel surfaces permitting displacement of any point on the yoke with respect to said housing means in a first group of planes orthogonal to and in a second group of planes parallel to the long axis of the cathode ray tube neck portion.
Claim 9
Dependent Claim
170 words
An improved adjustable deflection yoke assembly for a cathode ray tube having a funnel portion and a neck portion, said assembly comprising: a. a yoke encircling the tube neck portion; b. housing means including a shell enclosing said yoke and further including front and rear means for engaging the cathode ray tube at the funnel portion and the neck portion respectively; c. said housing means having a first slot defined by a first pair of opposing substantially parallel surfaces; d. adjustable Means secured to said yoke, e. fastener means extending through said first and said second slots at the intersection thereof, said fastener means being adapted to prevent relative movement between said ajdustable means and said housing means; f. said first and second pairs of opposing substantially parallel surfaces permitting displacement of any point on the yoke with respect to said housing means in a first group of planes orthogonal to and in a second group of planes parallel to the long axis of the cathode ray tube neck portion.
Claim 10
Dependent Claim
40 words
The invention of claim 7 wherein said first pair of opposing substantially parallel surfaces are substantially parallel to said axis of the cathode ray tube and said second pair of opposing substantially parallel surfaces are substantially orthogonal to said axis.
Claim 11
Dependent Claim
20 words
The invention of claim 8 wherein said adjustable means includes fastening means extending through both said first and second slots.
Claim 12
Dependent Claim
45 words
The invention of claim 8 wherein said yoke has a rear flange portion including an arcuate surface and said adjustable means includes an adjustable pitch correction element secured to the lower portion of said shell and bearing upon said arcuate surface for achieving movement thereof.
