Patent number: 10663666Abstract: This invention is a method and system for addressing structural weaknesses and geometric differentials introduced to a cable when splicing optic fibers. The apparatus and method utilize structurally integrated layers of protective polymers and bonding materials selected for strength and flexibility relative to their thickness. This results in an apparatus having a minimally increased circumference compared to the cable. The method and apparatus include one or more strengthening layers which allow the repaired cable substantially similar flexibility compared to the cable, but prevent formation of sharp bends or kinks. The strengthening layers also allow the repaired cable a resistance to tension similar to the original cable. The method and apparatus further include an outer layer having a geometric configuration which includes sloped terminating ends designed to prevent the reinforced area of the cable from being damaged by the force of objects or substances in contact with cable.Type: GrantFiled: December 5, 2013Date of Patent: May 26, 2020Assignee: United States of America as represented by the Secretary of the NavyInventors: Jeffrey M.

Patent number: 10487980Abstract: A pressure clamp for connecting pressure vessel segments and method can include a pair of semi-circular sections, which can be placed around the ends of the segments, so that there is a slight gap between the semi-circular sections. The inner surfaces of the semi-circular sections can be formed with two notches with beveled surfaces. The beveled surfaces can engage corresponding slanted surfaces on the segment ends, to urge the segments towards each other as the clamp is tightened. A pair of jack screws can be threaded through the semi-circular sections so that the jack screws extend slightly outwardly from one of the sections and contact the other section at the beginning of the tightening process, to establish an initial assembly gap. As fasteners tighten the clamp around the segment, the jack screws can be backed out to maintain a uniformly decreasing assembly gap between the semi-circular sections.Type: GrantFiled: August 9, 2017Date of Patent: November 26, 2019Assignee: United States of America as represented by Secretary of the NavyInventor: Brandon J.
