Publication number: 20240122276Abstract: Aspects herein are directed to an apparel item that promotes thermo-regulation through the use of engineered openings, venting, and/or stand-off structures. In exemplary aspects, 20-45% of the apparel item may comprise the engineered openings. Vents may be positioned on the apparel item in areas that experience high amounts of air flow to help channel air into the apparel item. The stand-off structures may be positioned on an inner-facing surface of the apparel item where they help to create a space between the apparel item and the wearer's body surface in which air can flow and help cool the wearer by promoting evaporative cooling.Type: ApplicationFiled: December 8, 2023Publication date: April 18, 2024Inventors: Collin Bailey, Kim D.

Patent number: 11959368Abstract: A system for protecting an Electrical Submersible Pump (ESP) string from gas slugs in a downhole well environment. The system comprises an intake tube having a first and second end and one of a packer having a bypass channel and an inverted shroud coupled to the intake tube and the ESP string. The intake tube is independent of a pump and a motor of the ESP string. The system can comprise a bypass tube for channeling the gas slug downstream of the pump. The bypass tube is integrated with the packer. The inverted shroud is coupled with the first end of the intake tube and a section of production tubing downstream from the pump and the motor. The inverted shroud forms a bypass path channel within a casing annulus.Type: GrantFiled: May 4, 2022Date of Patent: April 16, 2024Assignee: HALLIBURTON ENERGY SERVICES, INCInventors: Donn J.
