Patent number: 12251315Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.Type: GrantFiled: May 23, 2022Date of Patent: March 18, 2025Assignees: SMITH & NEPHEW, INC., SMITH & NEPHEW ORTHOPAEDICS AG SMITH, NEPHEW ASIA PACIFIC PTE LIMITEDInventors: Lance Terrill, Shawn Roman, Timothy R.

Patent number: 10888818Abstract: An integrated mercaptan extraction and/or sweetening and thermal oxidation and flue gas treatment process for a wide variety of sulfur, naphthenic, phenolic/cresylic contaminated waste streams is described. It provides comprehensive treatment for the safe disposal of sulfidic, naphthenic, phenolic/cresylic spent caustic streams, disulfide streams, spent air streams, spent mixed amine and caustic streams (also known as COS solvent streams) from sulfur treating processes. It allows the use of regenerated spent caustic in the sulfur oxide removal section of the thermal oxidation system reducing the need for fresh NaOH. It may also contain an integrated make-up water system. The integration allows the use of the liquefied petroleum gas or other hydrocarbon feeds to the respective extraction or sweetening process to offset external fuel gas requirements for the thermal oxidation system and for the push/pull system of the spent caustic surge drum and optional hydrocarbon surge drum.Type: GrantFiled: September 5, 2019Date of Patent: January 12, 2021Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Jan De Ren, William J.
