Patents by Inventor David M. Gladwin

David M. Gladwin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210033170
    Abstract: 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.

  • Patent number: 10710143
    Abstract: 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.

  • Patent number: 10591022

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.

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. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member.
