Publication number: 20240073383Abstract: An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicant: FLIGHTSAFETY INTERNATIONAL INC.Inventors: David Michael Emig, Brock Alan Ebert, Terry Richard Linn

Patent number: 8110150Abstract: A polymerization reactor for creating drag-reducing polymer having a reservoir and at least one heat exchanger plate in fluid communication with a coolant source, wherein each heat exchanger plate may be disposed on a lid. The heat exchanger plates are treated and/or covered to provide that the exchanger plates can be readily disengaged from the drag-reducing polymer. The polymerization reactors of the present invention permit large amounts of polymer to be formed in each reactor batch. Preferably, polymers are formed in the polymerization reactor by bulk polymerization. Methods for forming drag-reducing polymers are also disclosed.Type: GrantFiled: October 28, 2009Date of Patent: February 7, 2012Assignee: Beta Technologie AGInventors: Gerald B. Eaton, Alan Ebert

Patent number: 7128813Abstract: A process for the high yield production of high purity glacial methacrylic acid (“HPMAA”) with minimization of decomposition of hydroxy isobutyric acid (HIBA). The HPMAA is substantially pure, specifically 99% pure or greater with a water content of 0.05% or less. This improved process involves the steps of providing a crude MAA stream which was formed by hydrolyzing acetone cyanohydrin and, therefore, includes HIBA which is an intermediate product of the hydrolysis reaction, and purifying that crude methacrylic acid stream in a series of successive distillation steps.Type: GrantFiled: April 22, 2003Date of Patent: October 31, 2006Assignee: Rohm and Haas CompanyInventors: Keith Frederick Briegel, James Clarence Day, Michael Stanley DeCourcy, Donald Alan Ebert, Jamie Jerrick John Juliette

Patent number: 6428272Abstract: Rotor disk stress is reduced in a bolted joint for connecting adjacent rotor disks in a gas turbine engine. The bolted joint includes a bolt hole formed in the first rotor disk and a tube disposed in the bolt hole such that a channel is defined between the tube and the bolt hole. A bolt is disposed in the tube such that a gap is defined between the bolt and the tube. The gap thermally insulates the bolt from hot fluid in the channel. A first passage provides fluid communication between the channel and a forward cavity, and a second passage provides fluid communication between the channel and an aft cavity. Hot fluid passing through the channel reduces thermal gradients in the first rotor disk. The tube thermally shields the bolt from the hot fluid to minimize differential thermal growth.Type: GrantFiled: December 22, 2000Date of Patent: August 6, 2002Assignee: General Electric CompanyInventors: Jason Francis Pepi, Todd Alan Ebert
