Patent number: 11958235Abstract: Methods, devices and systems for efficient 3D printing using a single compact device are set forth. Some embodiments utilize a circular-shaped build area revolving symmetrically around a single center point utilizing a continuous helical printing process. Laser diodes or vertical-cavity surface-emitting lasers (VCSELs) are utilized as an energy source for curing the print material. The VCSELs can be integrated with the print head and can form an array which can be staggered or linear. In some embodiments, the VCSELs (and the corresponding print head) can be connected to a rotating platform, which can rotate independently from the revolving build area. In some embodiments, a thermoelectric cooler and/or a fluid cooler can provide cooling to the VCSELS.Type: GrantFiled: September 15, 2021Date of Patent: April 16, 2024Assignee: Orange Maker, LLCInventors: Kurt Dudley, James Tersigni

Patent number: 11193330Abstract: A drilling machine for a wellbore is provided. The drilling machine may include a dynamic lateral pad that is movable between an extended and retracted position. In the extended position, the pad moves the drill bit in a direction for drilling. The drilling machine may include a dynamic lateral cutter that is movable between an extended and retracted position. In at least the extended position, the cutter engages the wellbore and removes formation. The drilling machine may include a monolithic or integral drill bit/drive shaft to reduce the distance between a positive displacement motor and a distal end of the monolithic or integral drill bit/drive shaft. The drilling machine may include separate cutting structures that have different rotational speeds and can further utilize the integral drill bit/drift shaft and/or a bent housing that generates an off-axis rotation which helps optimize the formation removal in the center area of the wellbore.Type: GrantFiled: August 21, 2018Date of Patent: December 7, 2021Assignee: XR Lateral LLCInventors: Edward Spatz, Michael Reese, James Dudley

Patent number: 11028716Abstract: A leaf seal assembly 10? is disclosed for use in a gap between a rotating component 1 and a stationary component 2, for example of a turbo-machine. The leaf seal assembly 10 comprises at least one leaf seal 20? having a generally planar surface. A runner 50? is coupled to a distal end of the least one leaf seal 20?. The at least one leaf seal 20? maintains the runner 50? in a first position away from the rotating component 1 in an unpressurised inoperative state. The runner 50? moves to a second position, close to, but not contacting, the rotating component 1 in a pressurised operative state. In some embodiments the at least one leaf seal is angled in the direction of the flow. In some embodiments a first leaf seal is vented. In some embodiments the leaf seal assembly is segmented. In some embodiments the runner comprises segments having a radial thickness which varies circumferentially.Type: GrantFiled: June 23, 2017Date of Patent: June 8, 2021Assignees: CROSS MANUFACTURING COMPANY (1938) LIMITED, CMG TECH LLCInventors: James Dudley, Clayton Grondahl, Aaron Bowsher

Publication number: 20110083658Abstract: A portable, disposable apparatus for lighting charcoal or other flammable material contained therein. A central compartment generally in the shape of a tube extends from a bottom portion of the apparatus up through the center of the main body of the apparatus. An ignition strip extends within the tube. The apparatus is made of paper or paperboard or other lightweight flammable, yet durable, material. The apparatus is used by lighting the bottom of the ignition strip, which thereby starts a fire within the central compartment. The fire in the tube then ignites the charcoal within the main body of the apparatus. As the charcoal burns, the apparatus eventually burns away, leaving the burning charcoal in a pile.Type: ApplicationFiled: January 6, 2010Publication date: April 14, 2011Applicant: Design AnnexInventors: James Dudley, Peter Dieterich, JR., Mike Simonian, Maaike Evers
