Patent number: 11486465Abstract: A protected synthetic tensile member assembly including one or more fixed terminations used to transmit a tensile load from the tensile member to an external component. The tensile member includes access for inspection of its constituent fibers in at least one selected inspection region. The region is selected on the basis of the area of interest to the tensile member's use—such as the area of greatest stress concentration, the area of greatest abrasion, or an area of likely strand-to strand or overall cable translation. A removable cover is provided for the inspection region. A user may selectively remove this cover in order to gain access to the inspection region.Type: GrantFiled: May 24, 2022Date of Patent: November 1, 2022Assignee: Bright Technologies, LLCInventor: Richard V. Campbell

Patent number: 11441263Abstract: A method for producing a synthetic tensile member having a precisely known and stable length. The invention also comprises equipment configured to carry out the method. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. The length is then measured and a length adjusting component is incorporated into the tensile member to create a precise and stabilized length that is configured for the tensile member's particular application.Type: GrantFiled: August 17, 2020Date of Patent: September 13, 2022Assignee: Bright Technologies, LLCInventor: Richard V. Campbell

Patent number: 11378159Abstract: A termination system which improves the consistency and repeatability of the wicking of the liquid potting compound in the transition area between the potted and the imported filaments. The termination system controllably compresses the filaments within the transition area to produce repeatable wicking. The potting compound selected and the degree of compression employed combine to produce a desired wicking effect.Type: GrantFiled: August 31, 2018Date of Patent: July 5, 2022Assignee: Bright Technologies, LLCInventor: Richard V.

Patent number: 10808799Abstract: A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.Type: GrantFiled: September 21, 2017Date of Patent: October 20, 2020Assignee: Bright Technologies, LLCInventors: Richard V.

Patent number: 10718405Abstract: Devices and methods for loading a cable in order to create a desired distribution of the load among the cable's constituent strands. Strand terminations are applied to many—and possibly all of—the cable's strands. The ultimate goal is to connect the strand terminations to a collector in order to create an overall cable termination. The relationship between each strand termination and the collector is allowed to “float” using the inventive process while the cable is tensioned and an appropriate spatial relationship between each strand tensioner and the collector is determined. Once the appropriate relationship is found, it is configured to be repeatable (such as by recording its position for later application to the same or similar collector).Type: GrantFiled: December 5, 2017Date of Patent: July 21, 2020Assignee: Bright Technologies, LLCInventor: Richard V.

Patent number: 10710143Abstract: A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.Type: GrantFiled: June 11, 2019Date of Patent: July 14, 2020Assignee: Bright Technologies, LLCInventors: Richard V. Campbell, David M. Gladwin

Patent number: 10656033Abstract: A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.Type: GrantFiled: August 21, 2018Date of Patent: May 19, 2020Assignee: Bright Technologies, LLCInventor: Richard V.

Patent number: 10591022Abstract: A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. Once the potting compound in at least a portion of the cavity has transitioned sufficiently to hold the filaments at a desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.Type: GrantFiled: October 8, 2018Date of Patent: March 17, 2020Assignee: Bright Technologies, LLCInventors: Richard V.

Patent number: 10578191Abstract: Advanced components that are useful in providing a compact overall cable termination for a multi-stranded cable and in providing for the control and inspection of the individual components of a multi-stranded cable. Multiple individual cable strands are provided with a termination on their free end. These terminations are connected to a collector. An advanced collar is provided that assists in the transition of the strands as they leave the collector and transition to the structure found in the free portion of the cable.Type: GrantFiled: April 22, 2015Date of Patent: March 3, 2020Assignee: Bright Technologies, LLCInventor: Richard V Campbell
