Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
An arrangement for mounting and adjusting a deflection-coil holder for a color-picture tube comprising: a mounting member connected to the conical portion of an envelope of said tube; at least three sleeve carriers are secured to said mounting member; a guide groove in each of said carriers; straddling dowels floatingly retained in each of said guide grooves and each bore in said sleeve carriers, said straddling dowels being attached to said deflection-coil holder; and screws to be screwed into each of said straddling dowels where tightening of said screws controls the depth of immersion of said straddling dowels into said bores of said sleeve carriers and the position of said straddling dowels in said guide grooves of said deflection-coil holder is fixed.
Claim 2
Dependent Claim
122 words
An arrangement for mounting and adjusting a deflection-coil holder for a color-picture tube comprising: a mounting member connected to the conical portion of an envelope of said tube; at least three sleeve carriers are secured to said mounting member; a guide groove in each of said carriers; straddling dowels floatingly retained in each of said guide grooves and each bore in said sleeve carriers, said straddling dowels being attached to said deflection-coil holder; and screws to be screwed into each of said straddling dowels where tightening of said screws controls the depth of immersion of said straddling dowels into said bores of said sleeve carriers and the position of said straddling dowels in said guide grooves of said deflection-coil holder is fixed.
Claim 3
Dependent Claim
20 words
An arrangement according to claim 1, wherein said straddling dowel includes a bead on the end thereof adjacent said screws.
Claim 4
Dependent Claim
29 words
An arrangement according to claim 2, wherein said bead is a circular ring plate which aids in clamping said straddling dowel to said deflection-coil holder upon tightening said screws.
Claim 5
Dependent Claim
67 words
An arrangement according to claim 2, wherein said bead is a spherical segment; and said screws are provided with a spherical surface; and further including a pair of discs each provided with spherical surface to form a ball joint with said spherical surface of said screws, said ball joint being maintained in position by tightening said screws, thus firmly clamping said straddling dowel to said deflection-coil holder.
Claim 6
Dependent Claim
68 words
An arrangement according to claim 1, wherein said straddling dowel includes a non-slotted smooth shaft portion having a diameter cooperating with the diameter of the bore inside said sleeve carriers are chosen to be in such a relation to each other as to result in a cylinder guide so that said smooth shaft portion is permitted to enter a predetermined amount into the bore of said sleeve carriers.
