Abstract
Abstract An arrangement in which the antenna for a TV receiver may be oriented to an optimum position by the viewer from a remotelylocated position from the receiver. Antennas for VHF and UHF are each linked to rotary gears driven by a motor. Operation of the motor is controlled by the viewer by a remotely-located switch. The switch is held in depressed position to rotate the antennas by the motor to an optimum position in which the picture displayed by the picture tube of the TV receiver, is sharpest and possesses the greatest definition.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
208 words
An arrangement for controlling the positioning of antenna, comprising: a supporting housing; a first rotary member supported by said housing and being rotatable with respect to said housing, said first rotary member carrying a first antenna; a second rotary member rotatable supported on said housing and carrying a second antenna, said second rotary member being substantially concentric with said first rotary member; a ring gear with internal teeth coupled to said first rotary member; a spur gear with external teeth coupled to said second rotary member, said ring gear and said spur gear being concentrically rotatable relative to each other; a pinion gear meshing simultaneously with said spur gear and said ring gear; an electrical motor with an output shaft drivingly coupled to said pinion gear for rotating said pinion gear when energized, said spur gear rotating in a direction opposite to the direction of rotation of said ring gear when said pinion gear is rotatably dRiven by said electrical motor so as to rotate said first and second rotary members in opposite directions relative to each other; and switching means remotely located from said housing and connected to said motor for remotely controlling the operation of said motor and thereby controlling remotely the positioning of said antennae.
Claim 2
Dependent Claim
208 words
An arrangement for controlling the positioning of antenna, comprising: a supporting housing; a first rotary member supported by said housing and being rotatable with respect to said housing, said first rotary member carrying a first antenna; a second rotary member rotatable supported on said housing and carrying a second antenna, said second rotary member being substantially concentric with said first rotary member; a ring gear with internal teeth coupled to said first rotary member; a spur gear with external teeth coupled to said second rotary member, said ring gear and said spur gear being concentrically rotatable relative to each other; a pinion gear meshing simultaneously with said spur gear and said ring gear; an electrical motor with an output shaft drivingly coupled to said pinion gear for rotating said pinion gear when energized, said spur gear rotating in a direction opposite to the direction of rotation of said ring gear when said pinion gear is rotatably dRiven by said electrical motor so as to rotate said first and second rotary members in opposite directions relative to each other; and switching means remotely located from said housing and connected to said motor for remotely controlling the operation of said motor and thereby controlling remotely the positioning of said antennae.
Claim 3
Dependent Claim
51 words
The arrangement as defined in claim 1 wherein said ring, spur and pinion gears are arranged such that said second rotary member rotates at a higher rate of speed than said first rotary member, thereby causing said second antenna to rotate at a higher rate of speed than said first antenna.
Claim 4
Dependent Claim
35 words
The arrangement as defined in claim 1 introducing means for causing said electrical motor to reverse direction of rotation when said first rotary member, and consequently said first antenna, has rotated through a predetermined angle.
Claim 5
Dependent Claim
14 words
The arrangement as defined in claim 3 wherein said predetermined angle comprises substantially 180*.
Claim 6
Dependent Claim
60 words
The arrangement as defined in claim 3 wherein said reversing means includes stop means coupled to a least one of said rotary members for interfering with rotation thereof, said motor including means for reversing the rotational direction thereof when a stopping force of a predetermined value is applied to the output shaft thereof through said at least one rotary member.
Claim 7
Dependent Claim
60 words
The arrangement as defined in claim 3 wherein said reversing means includes stop means coupled to at least one of said gears for interfering with rotation thereof, said motor including means for reversing the rotational direction thereof when a stopping force of a predetermined value is applied to the output shaft thereof through said at least one of said gears.
Claim 8
Dependent Claim
47 words
The arrangement as defined in claim 6 wherein said stop means include a pair of stop members extending from said ring gear, and a cooperating member fixedly mounted relative to said ring gear and against which said stop members abut to stop rotation of said ring gear.
Claim 9
Dependent Claim
19 words
The arrangement as defined in claim 7 wherein said cooperating member is a projection extending from said supporting housing.
Claim 10
Dependent Claim
53 words
The arrangement as defined in claim 7 comprising one cooperating member and a pair of stop members projecting from said ring gear and substantially diametrically opposed relative to said ring gear to cause reversing of direction of rotation of said motor whenever said ring gear has rotated through an angle of substantially 180*.
Claim 11
Dependent Claim
35 words
The arrangement as defined in claim 1 wherein said antenna carried by said rotary member is for VHF TV receiver operation and said second antenna carried by said second rotary member is for UHF operation.
Claim 12
Dependent Claim
27 words
The arrangement as defined in claim 10 including switching means on said supporting housing for switching the operation of the antennas selectively between VHF and UHF operation.
Claim 13
Dependent Claim
44 words
The arrangement as defined in claim 1 wherein said motor includes means for reversing the direction of the output shaft thereof when a stopping force of a predetermined value is applied to said output shaft by said antenna abutting against a fixed, foreign object.
Claim 14
Dependent Claim
34 words
The arrangement as defined in claim 1 wherein said motor includes means for causing the reversal of direction of rotation of the output shaft thereof for substantially every alternate operation of said switching means.
