  • Patent number: 10323466
    Abstract: An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with screw jacks and a means of stabilization during substructure raising.

  • Publication number: 20180085564
    Abstract: A drug-impregnated sleeve for encasing a medical implant is provided. In one embodiment, the sleeve may include a body made of a biologically-compatible material that defines an internal cavity configured to receive the medical implant. In one embodiment, the biologically-compatible material is bioresorbable. The body may include a plurality of apertures, such as perforations or holes, extending from the cavity through the body. The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site. In one embodiment, the body is made from at least one sheet of a biologically-compatible material.

  • Publication number: 20160287527
    Abstract: A flexible body comprises a polymer film having a first surface and an opposing second surface. The polymer film has a plurality of apertures extending from the first surface to the second surface and a plurality of raised lips protruding from the first surface such that each of the plurality of apertures is surrounded by one of the plurality of raised lips. A method of producing a polymer film comprises placing a polymer solution into a one sided mold having a plurality of protrusions extending from a bottom of the mold wherein the polymer solution is characterized by a viscosity that inhibits the unaided flow of the polymer throughout the mold; urging the polymer solution around each of the plurality of protrusions; and solidifying the polymer solution.
