Patent number: 11229965Abstract: A method for machining a workpiece to provide a toothed member having a desired tooth pattern. The workpiece is machined to a first depth using a cutting tool, thereby forming a semi-finished tooth pattern, the first depth less than a full depth to which the workpiece is to be machined to provide the desired tooth pattern. Dimensions of the semi-finished tooth pattern are acquired and compared to nominal dimensions. If the acquired dimensions are not within a tolerance of the nominal dimensions, the geometry of the cutting tool is modified for correcting deviations of the acquired dimensions from tolerance and the workpiece further machined by the modified cutting tool. Once the dimensions of the semi-finished tooth pattern are within tolerance, the workpiece is machined to the full depth for providing the desired tooth pattern.Type: GrantFiled: March 30, 2020Date of Patent: January 25, 2022Inventors: William Ferry, Mario Blais, Yan Cousineau

Patent number: 9728315Abstract: An electromagnetic actuator includes a coil that is selectively energizable by an electric current. The electromagnetic actuator further includes an armature having a outwardly extending prong. The armature is movably disposed with respect to the coil such that when the coil is energized with the electric current, the armature moves in relation to the coil and disposing thereby the prong on a first side of the coil. A flux gatherer is provided to be disposed around a second side of the coil, thereby channeling magnetic flux emanating from the coil back into the armature and prong.Type: GrantFiled: February 28, 2014Date of Patent: August 8, 2017Assignee: GOVERNORS AMERICA CORPORATIONInventors: Arni Atlason, Derek Custer, William Ferry
