Patent number: 10600539Abstract: Apparatus and methods for manufacturing magnets, and magnets, having magnetically oriented grains, and apparatus including such magnets. The field of a permanent magnet may be shaped by applying an external field to the material from which the magnet is made in such a way as to magnetize different regions of the material in different directions. The apparatus may include, and the methods may involve, a metal-powder press that may press metal powder in the presence of a magnetic field. The press may compress the powder in an axial direction. The field may have flux lines that are transverse to the axial direction. The field may have flux lines that are along the axial direction.Type: GrantFiled: March 3, 2016Date of Patent: March 24, 2020Assignee: Magnetic Technologies AGInventors: Gerhard Martinek, Urs Wyss

Patent number: 10292826Abstract: A knee prosthesis comprising a femur component defining a ball-like femoral condyle and a tibia component defining a cavity on its medial side corresponding to the ball-like condyle. The knee prosthesis enables pivoting of the tibia component about the medial side of the femur component as a function of the flexion angle ? as long as there is joint compression applied to the knee prosthesis as exemplified by muscle forces, weight, and ligament tensions, to enforce contact between the tibia component and the femur component. The geometries of the spherical load bearing surfaces of the medial tibia condyle and medial femur condyle provide the kinematic degrees of freedom and the geometric constraints required for proper guiding of the rolling and sliding surfaces of the femoral component and tibial component during articulation of the present knee prosthesis.Type: GrantFiled: September 3, 2015Date of Patent: May 21, 2019Assignee: Orthopedic Innovation Centre Inc.Inventors: Urs Wyss, Shahram Amiri, Theodore Derek Vernon Cooke

Publication number: 20160151162Abstract: A knee prosthesis for a knee joint with a medial ball-like femoral condyle and with a width “w” is characterized on the lateral compartment by:—a trace-line “Lt1” of contact points “Pt1” for the tibia component (2) as a predetermined curve (15) on a spherical surface “Sc1”, which has its centre at the centre Mb of the medial ball 1 and which has a radius in the range “Rc1”=0.65 w+/?0.25 w—a trace-line “Lt2” of common contact points “Pt2” at given flexion angles ? for a similar spherical surface “Sc2” attached to the femoral component with radius “Rc2”=Rc1, whereby at a given flexion angle ? there exists a plane “E1” through the centre Mb and the common contact point Pt1/Pt2, which contains the same guiding curves “Bi”, “Be” on the tibial and on the femoral components, “Bi” towards medial and “Be” towards lateral, both of which stay in a geometrically fixed relation to the common contact point Pt1/Pt2, and—guiding curves “Bi” and “Be”, which generate an enforced gilding and rolling movement in both directions.Type: ApplicationFiled: September 3, 2015Publication date: June 2, 2016Inventors: Urs WYSS, Shahram AMIRI, Theodore Derek Vernon COOKE

Patent number: 4787908Abstract: An endoprosthetic metatarsal-phalangeal replacement joint is described. The joint includes a distal metatarsal component having a part-spherical convex distal superior phalangeal articular surface, and two inferior "side-by-side" sesamoidal articular surfaces, separated by an intersesamoidal ridge. The proximal phalangeal component is provided with a proximal circular surface at least a major portion of which has a part spherical concave surface having similar radius of curvature as the distal superior phalangeal surface of the metatarsal component. Natural, natural-resurfaced or prosthetic sesamoids are secured to a flexible mesh element arranged to be secured between the phalangeal component and the phalanx so that the sesamoids are positioned for articulation with the two inferior sesamoidal surfaces of the distal metatarsal component.Type: GrantFiled: April 30, 1987Date of Patent: November 29, 1988Assignee: Queen's University at KingstonInventors: Urs Wyss, Gerald A.

Patent number: 4469530Abstract: To reduce the hardening distortion during the case hardening of large toothed rims or gear wheels formed of steel the toothed rim or the like during cooling thereof, starting from the hardening temperature, is shrunk during the .gamma./.alpha. transformation of its core material upon a support body member, and then there is limited, during the further cooling to room temperature, the increase of the stresses in the toothed rim in that the support body member is inserted into the toothed rim in a pre-heated condition. The material of the support body member has a greater coefficient of thermal expansion than that of the toothed rim.Type: GrantFiled: June 11, 1982Date of Patent: September 4, 1984Assignee: Maag Gear-Wheel & Machine Company LimitedInventors: Urs Wyss, Johannes Federer
