Publication number: 20230387747Abstract: A method is disclosed for an innovative assembly of the electrical conditioning system connected to a water-based energy capturing device such as wave, hydrokinetic, or tidal machines to increase the efficiency of electrical power transmission between the energy capturing assembly and a load. The assembly favors the use of an active rectifier as the electrical conditioning system to provide both rectification and voltage regulation in a single system. The active rectifier can be configured to output a higher direct current (DC) bus voltage compared to passive rectifier solutions that both decrease the required size of the transmission cable conductors and transmission losses.Type: ApplicationFiled: April 27, 2023Publication date: November 30, 2023Inventors: Derek Neufeld, Lynn Tessier, Townes Lee

Patent number: 9939011Abstract: A working end of a rotary shaft extends through a bearing supported at a distal end of a cantilever housing, the shaft's working end being subjected to transverse loading. The bending stiffness of the system is matched so that the angular deflection of the shaft and supporting cantilever housing are coordinated to minimize angular misalignment at the bearing. A cantilever system provides for apparatus and methodology demonstrating arrangements characterized by an operational ease for submersion of the working end in a fluid and ease of access to the bearing. Mitigation of misalignment enables the use of radial bearings.Type: GrantFiled: May 6, 2015Date of Patent: April 10, 2018Assignee: Advantage Products Inc.Inventors: Lynn Tessier, Nicholas Joseph Schock

Patent number: 9534482Abstract: A method is provided for applying a thermal process to a lower zone underlying an overlying hydrocarbon zone with thermal energy from the thermal process mobilizing oil in the overlying zone. The lower zone itself could be a hydrocarbon zone undergoing thermal EOR. Further, one can economically apply a thermal EOR process to an oil formation of low mobility and having an underlying zone such as a basal water zone. Introduction gas and steam, the gas having a higher density than the steam, into the underlying zone displaces the basal water and creates an insulating layer of gas between the steam and the basal water maximizing heat transfer upwardly and mobilizing viscous oil greatly reducing the heat loss to the basal water, economically enhancing production from thin oil bearing zones with underlying basal water which are not otherwise economic by other known EOR processes.Type: GrantFiled: December 11, 2013Date of Patent: January 3, 2017Assignee: R.I.I.

Publication number: 20060272804Abstract: A self-aligning stuffing box having a spherical joint between the upper and lower portions of the housing permits universal movement of the upper portion relative to the lower portion to permit a rod to pass through the bore if the axis of the rod is misaligned relative to the axis of the bore in each of the upper and lower housing portions. An energized seal in the upper housing resides at or below the spherical joint due to a downwardly depending central portion of the upper housing which extends into a recess formed in the lower housing permitting the height of the stuffing box to be relatively short. A second seal is positioned above the first seal and may be spaced sufficiently above the first seal to permit a flapper valve to be installed between the seals. The flapper valve is mounted through a port in the upper housing which is accessible without disassembly of the stuffing box, the seals or the wellhead.Type: ApplicationFiled: June 3, 2005Publication date: December 7, 2006Inventors: Lynn Tessier, John Doyle, James Weber

Publication number: 20050269889Abstract: A frameless switched reluctance motor (SRM) has a stator sandwiched between two housings. Axial load on the rotor shaft is directed through a first bearing, through the first housing to the stator and through the second housing to a motor support. Heat is dissipated using low-loss electrical steel, one or more air movers and air passages through the motor. Preferably a stator profile enables the air passages to be formed through the stator's lamination stack. Optionally air is routed through passages between the coils and through air passages along the air gap and radially through passages between an upper and a lower stator. A first self aligning bearing adapts to misalignment between the first housing and the shaft and a second bearing is provided with transverse movement. Preferably, the frameless motor is adapted for support to a wellhead for driving a downhole rotary pump and a rotary rod string.Type: ApplicationFiled: June 6, 2005Publication date: December 8, 2005Inventors: Lynn Tessier, John Doyle, James Weber

Publication number: 20050263293Abstract: A tensioning tool for connection with a tubing hanger and tubing string suspended from the tubing hanger retained in a dognut by a hanger retainer. Preferably the hanger retainer is temporarily engaged to the top of the tensioning pup for release therefrom once a lower end of the tubing has been fixed by a tubing anchor and the tubing has been lifted a tensioning distance. The hanger retainer is then engaged with the tubing hanger for suspending the tensioned tubing from the dognut locked in the wellhead. The dognut and the hanger retainer have co-operating locking faces which prevent rotation of the hanger retainer in the dognut once the locking faces are mated which assists in maintaining torque applied to the tubing string which may have been applied to rotationally set the tubing anchor. More preferably, the tensioning pup has a series of gradations marked on the pup for measuring the amount of tension applied to the tubing string.Type: ApplicationFiled: May 26, 2005Publication date: December 1, 2005Inventors: Lynn Tessier, James Weber, John Doyle
