Patent number: 11680038Abstract: The present disclosure relates to fluid bed processes that utilize silica particles as a fluidization aid. The process comprises reacting one or more reactants in a reactor comprising a fluid bed to form a product. The fluid bed comprises a catalyst composition comprising a catalyst and an inert additive composition comprising silica particles from 0.5 wt % to 30 wt %, based on the total weight of the catalyst composition. The silica particles are discrete, inert particles that are mixed with the catalyst in the fluid bed.Type: GrantFiled: June 9, 2021Date of Patent: June 20, 2023Assignee: Ascend Performance Materials Operations LLCInventors: Yawu T. Chi, James Sutton, Ali Akhavan, Celia L. Kniepmann, Matthew D. Cox, Valerie S. Monical

Patent number: 10265787Abstract: A power saw includes a bevel member and a cutting assembly pivotably connected to the bevel member. The cutting assembly includes a blade, a blade guard at least partially covering the blade, and at least one machined cutting assembly surface. A laser alignment device is connected to the cutting assembly. The laser alignment device includes a laser body fixed to a slideable carriage having a machined carriage surface that directly engages the machined cutting assembly surface. The slideable carriage is configured to move relative to the machined cutting assembly surface with substantially only one degree of freedom defined by an axis of translation.Type: GrantFiled: April 28, 2010Date of Patent: April 23, 2019Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventors: Michael J. Lawlor, Srinath Srinivas, Matthew D. Cox, Zhao Rui, Pan Huaping, Brian H. Chung, Wojciech T. Pierga

Patent number: 8272304Abstract: An improved dust collection system for a miter saw comprising a hollow dust chute attached to a bevel post of a miter saw. The bevel post includes a top portion and a bottom portion and is pivotably attached to a miter saw table. The dust chute comprises an input port positioned to receive saw dust resulting from a cutting operation, an exit port and a funnel body extending from the input port to the exit port. At least a portion of the funnel body extends toward an opening located in a guard of a cutting arm assembly. The cutting arm assembly is pivotably connected to the top portion of the bevel post; wherein, the dust chute remains substantially stationary, as the cutting arm assembly is moved during the cutting operation.Type: GrantFiled: January 8, 2010Date of Patent: September 25, 2012Assignee: Robert Bosch GmbHInventors: Michael J. Lawlor, Matthew D. Cox, Wojciech T. Pierga

Patent number: 7404707Abstract: A hydraulic sample mounting press utilizes a face seal against the top face of a molding cylinder. The face seal employs a hydraulic cylinder to press a disk-shaped surface of a cap piece against the top annular face of the mold cylinder for a metallographic mounting press. The face seal cylinder is mounted to a hydraulic fluid column that allows the face seal to rotate away from the mold cylinder for access to the molding cylinder and to rotate into place when a metallographic mount is to be molded.Type: GrantFiled: April 18, 2002Date of Patent: July 29, 2008Assignee: Leco CorporationInventors: Dwight F.
