Abstract
Abstract Tuning coil units for use in television tuners are provided which have been automatically aligned to the desired channel frequency by deforming the turns of the respective tuning coils in such manner as to cause them to take a permanent set at the proper inductance value to receive a desired television channel. The coil turns are deformed inwardly into a recess in the coil form so that the coil turns are tightly stretched about the coil form and maintain their adjusted inductance value during assembly and usage in the television tuner.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A tuning coil unit for use in a turret tuner, comprising an elongated support member of insulating material, means defining a longitudinally extending recess in said support member, a plurality of conductive terminal members positioned at spaced points along the length of said support member, a plurality of coils wound around said support member, means connecting the ends of said coils to different ones of said terminal members, the portions of said coils which overlie said recess means being bent inwardly toward the center of said support member by amounts such that said coils have predetermined values of inductance.
Claim 2
Dependent Claim
99 words
A tuning coil unit for use in a turret tuner, comprising an elongated support member of insulating material, means defining a longitudinally extending recess in said support member, a plurality of conductive terminal members positioned at spaced points along the length of said support member, a plurality of coils wound around said support member, means connecting the ends of said coils to different ones of said terminal members, the portions of said coils which overlie said recess means being bent inwardly toward the center of said support member by amounts such that said coils have predetermined values of inductance.
Claim 3
Dependent Claim
110 words
A coil assembly for use in a turret-type tuner, comprising an elongated insulating supporting member, a plurality of conductive terminal members spaced along the length of said support member, a plurality of coils wound around said support member, each of said coil being positioned between a different pair of said conductive terminal members and having the ends thereof connected to adjacent terminal members of each pair, means defining a groove in said support member which extends beneath a portion of the turns of each of said coils, said turn portions being permanently deformed at least partially into said groove by amounts such that said coils have predetermined values of inductance.
Claim 4
Dependent Claim
110 words
A coil assembly for use in a turret-type tuner, comprising an elongated insulating supporting member, a plurality of conductive terminal members spaced along the length of said support member, a plurality of coils wound around said support member, each of said coil being positioned between a different pair of said conductive terminal members and having the ends thereof connected to adjacent terminal members of each pair, means defining a groove in said support member which extends beneath a portion of the turns of each of said coils, said turn portions being permanently deformed at least partially into said groove by amounts such that said coils have predetermined values of inductance.
Claim 5
Dependent Claim
87 words
A tuning coil assembly, comprising an elongated insulating support member, a pair of conductive terminal members spaced along the length of said support member, a coil wound around said support member and having the ends thereof connected to said terminal members, means defining recess means in said support member extending beneath at least a portion of said coil, the portions of said coils above said recess means being deformed inwardly into said recess means by an amount such that said coil has a predetermined value of inductance.
Claim 6
Dependent Claim
87 words
A tuning coil assembly, comprising an elongated insulating support member, a pair of conductive terminal members spaced along the length of said support member, a coil wound around said support member and having the ends thereof connected to said terminal members, means defining recess means in said support member extending beneath at least a portion of said coil, the portions of said coils above said recess means being deformed inwardly into said recess means by an amount such that said coil has a predetermined value of inductance.
