Publication number: 20240173144Abstract: A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.Type: ApplicationFiled: December 4, 2023Publication date: May 30, 2024Inventors: Steve Wolfe, Bryan Becker, Tim Walnofer, Clint Boylan, Dan McPhillips, Michael Wang, Craig Kuhns, Garrett Ganske

Patent number: 11461886Abstract: A method, related system and related computer program product are provided for monitoring wear of teeth of a drum of a double roll crusher. A processor receives a digital video capturing rotation of the drum and the teeth. For each frame of the digital video, the processor segments the frame into groups of contiguous pixels, wherein each group is representative of one of the teeth. The processor determines parameter indicative of a geometry of at least one of the teeth based on segmented groups of contiguous pixels in at least one of the frames of the digital video. The processor generates a human-readable report based on the parameter indicative of the geometry of the at least one of the teeth.Type: GrantFiled: July 9, 2020Date of Patent: October 4, 2022Assignee: SYNCRUDE CANADA LTD.Inventors: Mark Polak, Dan Wolfe, Dustin Stuyt

Patent number: 11098253Abstract: A method for extracting bitumen from an oil sand slurry involves limiting the size of rock and clay lumps in the slurry to a first size, conditioning the slurry in a pipeline, screening the slurry through a rotary screening apparatus to remove the lumps that are larger than a second size, and subjecting the slurry to gravity separation to separate the bitumen as a bitumen froth. A fastener assembly for securing a screen panel to a drum shell of a rotary screening apparatus includes an outer insert for insertion into an aperture of a drum shell, an inner insert for insertion through an aperture of the screen panel and into an inward facing pocket of the outer insert, and a bolt for securing together the outer and inner inserts. An insert for removable insertion into an aperture of a drum of a rotary screening apparatus defines a screening aperture.Type: GrantFiled: April 16, 2020Date of Patent: August 24, 2021Assignee: SYNCRUDE CANADA LTD.Inventors: Ron Cleminson, Dan Wolfe, Michael Carniato, Stefano Chiovelli

Patent number: 10815066Abstract: A system for correcting transverse misalignment of a conveyor belt relative to a supporting pulley, includes a frame is pivotally attached to a stationary member. A guide surface engages the frame to guide pivoting of the frame about the pivot point simultaneously about a vertical axis and a longitudinally aligned axis. Idler rollers rotatably mounted on the frame define a rolling contact surface for the conveyor belt, which is concavely-shaped in a transversely-extending vertical plane. The pivoting of the frame causes the surface to impart a combined transverse pushing effect, torsional steering effect, and torsional tiling effect on the conveyor belt. An actuator applies a force to pivot the frame about the axis. A computer determines an amount of the misalignment based on a signal from a sensor, and automatically controls the actuator to pivot the frame, depending on the determined amount of the misalignment.Type: GrantFiled: April 9, 2019Date of Patent: October 27, 2020Assignee: SYNCRUDE CANADA LTD.Inventors: Michael Carniato, Dan Wolfe, Mark Polak, Yuxiang (Isaac) Wu, Soon Won Moon
