Patent number: 11808090Abstract: The force modulation system for a drill bit includes a cutter, a holder, a holder retention device, and a first force member. The cutter fits in the holder, and the holder fits in the drill bit. The holder retention device exerts a holder retention force in a first direction. The first force member exerts a first force in a second direction. The second direction is angled offset to the first direction so as that the cutting profile of the force modulation system is now variable in the second direction, according to the first force. There can also be a second force member to exert a second force in the first direction for more variability of the cutting profile in the first direction. The second force member can be made integral with the first force member.Type: GrantFiled: September 25, 2022Date of Patent: November 7, 2023Assignees: CNPC USA Corporation, Beijing Huamei Inc.

A billet of a dissolvable aluminum alloy is wrapped with a sheet cover so as to form a wrapped billet. The wrapped billet is extruded through an equal channel angular extrusion die with an extrusion angle ranging 90-135 degrees so as to form an extruded billet. The step of extruding is at a temperature ranging 150-250 degrees C., an extrusion rate ranging 0.003-0.010 inches per second, and a back pressure ranging 200-10000 psi. The dissolvable aluminum alloy of the extruded billet has a yield strength and ultimate tensile strength 50% greater than the initial yield strength and initial ultimate tensile strength.Type: ApplicationFiled: February 13, 2020Publication date: August 19, 2021Inventors: Jianhui XU, Timothy DUNNE, Yu SANG, Yi SONG, Wenhan YUE, Yu LIU, Xiongwen YANG

Publication number: 20210194079Abstract: The hybrid battery system has multiple discharge voltage plateaus and a greater charge capacity of metal in the negative electrode, while still having sufficient energy density and sufficient power capability to supply external devices. The charge capacity of the negative side is higher than the charge capacity of the positive side. There are two solvent compositions in the cathodic solution, and there is a transition from a first discharge voltage plateau to a second discharge voltage plateau at a voltage less than the first discharge voltage plateau. The battery system is safe, and the transition between discharge voltage plateaus provides an estimation of battery capacity that can indicate when the battery system is running out of power.Type: ApplicationFiled: December 22, 2020Publication date: June 24, 2021Inventors: Wu BI, Xiongwen YANG
