Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
Magnetic sensing apparatus comprising an elongated nonmagnetic cylindrical tube, a pair of directional magnetic field sensor means spaced apart in and fixed to said tube, said sensor means having individual magnetic axes approximately aligned with the longitudinal axis of said tube, and means for compensating for misalignment of the axis of either of said sensor means in said longitudinal axis, said compensating means comprising a nonmagnetic annulus having an opening through which said elongated tube extends freely and slidably longitudinally and circumferentially, said annulus carrying a body of easily magnetizable material and having mechanically adjustable means for fixing the annulus to said tube after said annulus has been moved longitudinally along said tube and circumferentially of said tube to a position at which substantial compensation for misalignment is attained.
Claim 2
Dependent Claim
129 words
Magnetic sensing apparatus comprising an elongated nonmagnetic cylindrical tube, a pair of directional magnetic field sensor means spaced apart in and fixed to said tube, said sensor means having individual magnetic axes approximately aligned with the longitudinal axis of said tube, and means for compensating for misalignment of the axis of either of said sensor means in said longitudinal axis, said compensating means comprising a nonmagnetic annulus having an opening through which said elongated tube extends freely and slidably longitudinally and circumferentially, said annulus carrying a body of easily magnetizable material and having mechanically adjustable means for fixing the annulus to said tube after said annulus has been moved longitudinally along said tube and circumferentially of said tube to a position at which substantial compensation for misalignment is attained.
Claim 3
Dependent Claim
23 words
Apparatus in accordance with claim 1, wherein said body comprises a rod extending radially of said annulus to the vicinity of said tube.
Claim 4
Dependent Claim
15 words
Apparatus in accordance with claim 1, wherein said mechanically adjustable means comprises a set screw.
Claim 5
Dependent Claim
123 words
Magnetic sensing apparatus comprising an elongated non-magnetic cylindrical tube, a pair of directional magnetic field sensor means spaced apart in and fixed to said tube, said sensor means having individual magnetic axes approximately aligned with the longitudinal axis of said tube, and means for compensating for misalignment of the axis of either of said sensor means with said longitudinal axis, said compensating means comprising a non-magnetic cylindrical cap closing one end of said tube and rotatably adjustable about said longitudinal axis, said cap carrying a body of easily magnetizable material eccentrically thereon and having means for fixing the cap to the tube after the cap has been rotated about said longitudinal axis to a position at which substantial compensation for misalignment is attained.
Claim 6
Dependent Claim
123 words
Magnetic sensing apparatus comprising an elongated non-magnetic cylindrical tube, a pair of directional magnetic field sensor means spaced apart in and fixed to said tube, said sensor means having individual magnetic axes approximately aligned with the longitudinal axis of said tube, and means for compensating for misalignment of the axis of either of said sensor means with said longitudinal axis, said compensating means comprising a non-magnetic cylindrical cap closing one end of said tube and rotatably adjustable about said longitudinal axis, said cap carrying a body of easily magnetizable material eccentrically thereon and having means for fixing the cap to the tube after the cap has been rotated about said longitudinal axis to a position at which substantial compensation for misalignment is attained.
Claim 7
Dependent Claim
17 words
Apparatus in accordance with claim 4, wherein said cap fits within said one end of said tube.
Claim 8
Dependent Claim
26 words
Apparatus in accordance with claim 5, wherein said means for fixing said cap to said tube comprises a pin extending from said cap to said tube.
