Abstract
Abstract A linear displacement transducer system in which a tension cable is attached to the object of which the relative displacement is to be measured and to the shaft of a shaft angle position transducer (SAPT) such that displacement of the object relative to the shaft results in rotation of the shaft. This displacement provides a measurable variation of the electrical characteristics of the transducer. A cylindrical housing containing the transducer is also provided together with a bracket having a circular opening for accommodating the cylindrical housing to permit positioning of the transducer housing in any orientation with respect to the object.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
A linear displacement transducer system for mounting on a body to provide an indication of the displacement of an object relative to the body and the transducer, comprising, in combination: a linear displacement transducer having a shaft and an output signal appearing at an output, having the value of the output signal a function of the angular position of the shaft; a tension cable having first and second ends, having the first end for attachment to the object of which the displacement is to be indicated, and having the second end wound about the shaft of the transducer such that the displacement of the object results in the rotation of the shaft of the transducer and a variation in the output signal of the transducer; a housing containing the transducer and shaft; a bracket having a base adapted for mounting on the body; clamping means attached to the bracket and the housing holding the housing and permitting the positioning of the housing in preselected orientations with respect to the base.
Claim 2
Dependent Claim
170 words
A linear displacement transducer system for mounting on a body to provide an indication of the displacement of an object relative to the body and the transducer, comprising, in combination: a linear displacement transducer having a shaft and an output signal appearing at an output, having the value of the output signal a function of the angular position of the shaft; a tension cable having first and second ends, having the first end for attachment to the object of which the displacement is to be indicated, and having the second end wound about the shaft of the transducer such that the displacement of the object results in the rotation of the shaft of the transducer and a variation in the output signal of the transducer; a housing containing the transducer and shaft; a bracket having a base adapted for mounting on the body; clamping means attached to the bracket and the housing holding the housing and permitting the positioning of the housing in preselected orientations with respect to the base.
Claim 3
Dependent Claim
68 words
The apparatus of claim 1 wherein: the housing is a substantially cylindrical housing; the bracket includes a section connected to the base having a substantially circular opening to accommodate the cylindrical housing; and the clamping means includes a first locking element connected to the section to hold the cylindrical housing in a fixed position within the section and to permit movement of the hOusing to other desired positions.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 wherein the cylindrical housing contains an opening for the tension cable, and said tension cable extending through said opening.
Claim 5
Dependent Claim
46 words
The apparatus of claim 2 wherein the clamping means includes a second locking element connected to the base and to the section to hold the section in a fixed position with respect to the bracket and to permit movement of the section to other desired positions.
Claim 6
Dependent Claim
58 words
The apparatus of claim 4 wherein: the section includes a substantially cylindrical portion; the base includes a substantially cylindrical opening to accommodate the cylindrical portion; and the second locking element is positioned to hold the cylindrical portion of the section in a fixed position within the base and to permit movement of the section to other desired positions.
Claim 7
Dependent Claim
45 words
The apparatus of claim 2 wherein the first locking element includes a locking screw adapted to vary the effective circumference of the substantially circular opening in the section so as to hold the cylindrical housing and permit movement of the housing to other desired positions.
Claim 8
Dependent Claim
89 words
The apparatus of claim 5 wherein: the first locking element includes a locking screw adapted to vary the effective circumference of the substantially circular opening in the section so as to hold the cylindrical housing and permit movement of the housing to other desired positions; and the second locking element includes a locking screw adapted to vary the effective circumference of the substantially circular opening in the base in order to hold the cylindrical portion of the section and to permit movement of the section to other desired positions.
Claim 9
Dependent Claim
11 words
The apparatus of claim 2 wherein the transducer is a potentiometer.
