Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
An apparatus for aligning equipment relative to an underwater vertically positioned conduit, comprising: an elongated body having first and second ends, spaced-apart first and second end portions, a chamber closed on the second end, extending through the body and open on the first end, and a plurality of spaced-apart, longitudinally aligned holding elements formed at each end portion, molded rubber externally covering the first and second end portions and second end of the body and being fixedly attached thereto, said rubber forming spaced-apart, longitudinally directed, laterally extending ribs on the holding elements of the first and second end portions of the body for entering and contacting the inner surface of the conduit and aligning equipment relative thereto; and at least one nozzle mounted on a side of the body in communication with the chamber for passing fluid laterally from the chamber for moving the tool laterally relative to the conduit.
Claim 2
Independent Claim
150 words
An apparatus for aligning equipment relative to an underwater vertically positioned conduit, comprising: an elongated body having first and second ends, spaced-apart first and second end portions, a chamber closed on the second end, extending through the body and open on the first end, and a plurality of spaced-apart, longitudinally aligned holding elements formed at each end portion, molded rubber externally covering the first and second end portions and second end of the body and being fixedly attached thereto, said rubber forming spaced-apart, longitudinally directed, laterally extending ribs on the holding elements of the first and second end portions of the body for entering and contacting the inner surface of the conduit and aligning equipment relative thereto; and at least one nozzle mounted on a side of the body in communication with the chamber for passing fluid laterally from the chamber for moving the tool laterally relative to the conduit.
Claim 3
Dependent Claim
31 words
An apparatus, as set forth in claim 1, wherein there are at least three fixedly attached, longitudinally directed rubber ribs on each of the first and second portions of the body.
Claim 4
Dependent Claim
23 words
An apparatus, as set forth in claim 1, wherein the end portion of each rib tapers toward a longitudinal axis of the body.
Claim 5
Dependent Claim
