Claim 1
Independent Claim
242 words
An antenna positioning indicating system comprising: an antenna means mounting said antenna for rotation a first gear operatively connected to said antenna mounting means, the angle of rotation of said first gear exactly corresponding to the angle of rotation of said antenna, a second gear meshed with said first gear, a first shaft mounted for rotation in fixed position with respect to said first gear, said second gear being mounted on said first shaft for rotation with it, a third gear also meshed with said first gear at a position diametrically opposite said second gear, a second shaft mounted for rotation in fixed position with respect to said first gear, said third gear being mounted on said second shaft for rotation with it, fourth and fifth gears mounted respectively on said first and second shafts for rotation with them and with said second and third gears respectively, a sixth gear meshed respectively with said fourth and fifth gears at diametrically opposite positions of said sixth gear, means mounting said sixth gear for rotation, indicating means operatively connected to said sixth gear to indicate the angular position of the sixth gear, the sizes of the gears being such that the angular rotation of said sixth gear means is a multiple of the angular rotation of said antenna, the said positions of said gears averaging out eccentricity errors of said gears whereby the angular position indicated for said antenna is an accurate multiple thereof.
Claim 2
Dependent Claim
242 words
An antenna positioning indicating system comprising: an antenna means mounting said antenna for rotation a first gear operatively connected to said antenna mounting means, the angle of rotation of said first gear exactly corresponding to the angle of rotation of said antenna, a second gear meshed with said first gear, a first shaft mounted for rotation in fixed position with respect to said first gear, said second gear being mounted on said first shaft for rotation with it, a third gear also meshed with said first gear at a position diametrically opposite said second gear, a second shaft mounted for rotation in fixed position with respect to said first gear, said third gear being mounted on said second shaft for rotation with it, fourth and fifth gears mounted respectively on said first and second shafts for rotation with them and with said second and third gears respectively, a sixth gear meshed respectively with said fourth and fifth gears at diametrically opposite positions of said sixth gear, means mounting said sixth gear for rotation, indicating means operatively connected to said sixth gear to indicate the angular position of the sixth gear, the sizes of the gears being such that the angular rotation of said sixth gear means is a multiple of the angular rotation of said antenna, the said positions of said gears averaging out eccentricity errors of said gears whereby the angular position indicated for said antenna is an accurate multiple thereof.
Claim 3
Dependent Claim
30 words
A system as in claim 1, including means for converting the angular position of said sixth gear means to an electrical position signal, which is applied to said indicating means.
Claim 4
Dependent Claim
36 words
A system as in claim 2 where said amplification of the angular position of said antenna is by an approximate factor of 36 thereby reducing the electrical error of said signal converting means by said factor.
Claim 5
Dependent Claim
26 words
A system as in claim 2 including flexible coupling means for accommodating movement of said gear means in a direction perpendicular to its direction of rotation.
Claim 6
Dependent Claim
17 words
A system as in claim 2 where said indicating means includes means for recording said antenna position.
Claim 7
Dependent Claim
41 words
A system as in claim 1 including means for preventing backlash between (1) said fourth and sixth gear means, (2) said fifth and sixth gear means, (3) said first and second gear means, and (4) said first and third gear means.
