Publication number: 20240138994Abstract: An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.Type: ApplicationFiled: January 9, 2024Publication date: May 2, 2024Inventors: Mark A. Heldreth, Travis D. Bennett, Amitkumar M. Mane, Michael J. Rock, Thomas E. Wogoman, Stephen E. White

Patent number: 8651188Abstract: A gas lift valve that has a longitudinally extending tubular body having an inlet and an outlet, a flow path extending between the inlet and the outlet, and a flow tube located inside the body. The flow tube is translatable in the axial direction between at least a first and a second position. A venturi orifice located inside the body along the flow path. A seal part is located proximate to the outlet of the body. A flapper is connected with the body by way of a hinge part and the flapper has at least a first open position and a second closed position. The closed position is where the flapper contacts the seal thereby closing the flowpath and the second closed position is where the flapper does not contact the seal and does not close the flowpath.Type: GrantFiled: December 30, 2009Date of Patent: February 18, 2014Assignee: Schlumberger Technology CorporationInventors: Kevin T. Scarsdale, Jason Kamphaus, Jacob Hahn, Thomas M. White

Patent number: 8225874Abstract: An apparatus that is usable with a well includes a gas lift valve and an isolation member. The gas lift valve includes a valve element that is located between an annulus and a passageway of a tubing. The valve element is adapted to selectively open and close to control fluid communication through the valve element. The isolation member is adapted to in a first state, isolate the valve element from at least one of the annulus and the passageway and in a second state, permit fluid communication between the valve element and the annulus or passageway.Type: GrantFiled: January 7, 2010Date of Patent: July 24, 2012Assignee: Schlumberger Technology CorporationInventors: Tyson R.

Patent number: 4258877Abstract: A damper blade control for regularing the flow of conditioned air through a supply air duct and into a zone. The control comprises an electric motor for use with a source of electrical energy for moving the damper blade between a minimum air flow position and a maximum air flow position, and a thermostatic switch electrically positioned between the motor and the source of electrical energy for connecting the motor thereto to change the position of the damper blade in response to changes in the temperature of the zone. The control further comprises maximum and minimum flow switches disposed outside the supply air duct for disconnecting the motor from the source of electrical energy when the damper blade reaches, respectively, the maximum and minimum air flow positions.Type: GrantFiled: August 30, 1979Date of Patent: March 31, 1981Assignee: Carrier CorporationInventor: Thomas M.
