Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced.
Claim 2
Dependent Claim
75 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced.
Claim 3
Dependent Claim
100 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; wherein each of said strain members is formed from a bundle of fibers of high tensile strength and a plastic jacket which encases said bundle.
Claim 4
Dependent Claim
100 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; wherein each of said strain members is formed from a bundle of fibers of high tensile strength and a plastic jacket which encases said bundle.
Claim 5
Dependent Claim
112 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutual opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; wherein each of said strain members is formed from a bundle of fibers of high tensile strength and a plastic jacket which encases said bundle, and wherein said bundle of fibers are longitudinally slidable within said jacket.
Claim 6
Dependent Claim
112 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutual opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; wherein each of said strain members is formed from a bundle of fibers of high tensile strength and a plastic jacket which encases said bundle, and wherein said bundle of fibers are longitudinally slidable within said jacket.
Claim 7
Dependent Claim
125 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; the product of the number of strain members in said outer layer times their average radial distance from the axis of the cable being substantially equal to the product of the number of strain members in said inner layer times their average radial distance from the axis of the cable.
Claim 8
Dependent Claim
125 words
An electromechanical cable comprising: a plurality of strain members arranged in inner and outer circumferential layers, the members in said two layers being helically twisted in mutually opposite directions; said strain members being of substantially rectangular cross-sectional configuration, the members in said inner layer being arranged with their larger dimension extending radially, and the members in said outer layer being arranged with their larger dimension extending circumferentially, whereby said two layers are substantially torque balanced; the product of the number of strain members in said outer layer times their average radial distance from the axis of the cable being substantially equal to the product of the number of strain members in said inner layer times their average radial distance from the axis of the cable.
