Patent number: 11787776Abstract: A method for producing an aromatic dianhydride includes reacting an aromatic diimide with a substituted or unsubstituted phthalic anhydride in an aqueous medium in the presence of an amine exchange catalyst to provide an aqueous reaction mixture including an N-substituted phthalimide, an aromatic tetraacid salt, and at least one of an aromatic triacid salt and an aromatic imide diacid salt. The method further includes removing the phthalimide from the aqueous reaction mixture by extracting the aqueous reaction mixture with an organic solvent and converting to the corresponding aromatic dianhydride. The extracting is carried out in an extraction column including a high specific surface area metal packing material and having an interface between the aqueous reaction mixture and the organic solvent that is at a level that is 14 to 85% of the height of the extraction column.Type: GrantFiled: June 4, 2019Date of Patent: October 17, 2023Assignee: SHPP GLOBAL TECHNOLOGIES B.V.Inventors: Robert John Werling, Simon Padmanabhan, Aaron Matthew Royer, Bradley Osborne, Christopher Poirier

Publication number: 20230327796Abstract: A microphone jammer includes an ultrasonic transducer for emitting an ultrasonic jamming signal to jam a microphone of an external electronic device. The apparatus includes a sound chamber that is shaped to direct the ultrasonic jamming signal towards an area for placement of an external electronic device that includes the microphone. The apparatus may include a base and a top portion connected to the base, with the ultrasonic transducer being in the top portion and the sound chamber being shaped to direct the ultrasonic jamming signal towards the base.Type: ApplicationFiled: June 2, 2021Publication date: October 12, 2023Inventors: David John NICKEL, Bruce John CLELAND, Evan Bradley Osborne MCDOUGALL, Kerry CHIN, Shawn STEVENSON, Morgan GILBERT

Publication number: 20130292511Abstract: An aerodynamic control system incorporates multiple Dielectric Barrier Discharge (DBD) flow control actuators adjacent a surface of an airborne vehicle in a path of laminar boundary layer flow over the surface. A control computer receives a control input and selectively distributes power to an activation array selected from the DBD flow control actuators for transition to a first operating condition tripping the laminar boundary layer at selected streamwise locations for turbulent flow. When the control computer removes the distributed power the DBD flow control actuators return to a second operating condition restoring the laminar boundary layer.Type: ApplicationFiled: May 2, 2012Publication date: November 7, 2013Applicant: The Boeing CompanyInventors: Bradley A. Osborne, Scott L. Schwimley, Joseph S. Silkey

Patent number: 8172547Abstract: A dielectric element barrier discharge pump for accelerating a fluid flow. In one embodiment the pump has a first dielectric layer having a first electrode embedded therein and a second dielectric layer having a second electrode embedded therein. The first and second dielectric layers are further supported apart from one another to form an air gap therebetween. A third electrode is disposed at least partially in the air gap upstream of the first and second electrodes, relative to a direction of flow of the fluid flow. A high voltage supplies a high voltage signal to the third electrode. The electrodes cooperate to generate opposing asymmetric plasma fields in the gap that create an induced air flow within the gap. The induced air flow operates to accelerate the fluid flow as the fluid flow moves through the gap.Type: GrantFiled: January 31, 2008Date of Patent: May 8, 2012Assignee: The Boeing CompanyInventors: Richard S. Dyer, Joseph S. Silkey, Bradley A. Osborne

Patent number: 8016245Abstract: A system for reducing overall drag of a mobile platform includes a surface on which an airflow forms a boundary layer and a generally normal shockwave. The airflow is at a first velocity that is one of transonic and supersonic. An oscillating jet injects and extracts a jet flow through the surface. The jet flow is at a second velocity that is substantially less than the first velocity. A recirculation region is upstream of the normal shockwave and is disposed at least partially in the boundary layer. The recirculation region is established at least by the oscillating jet. A generally oblique wave is established by the recirculation region and weakens the normal shockwave to reduce the overall drag experienced by the surface.Type: GrantFiled: October 18, 2006Date of Patent: September 13, 2011Assignee: The Boeing CompanyInventors: Ahmed A. Hassan, Bradley A. Osborne, Scott Schwimley, Garry Billman, Mary Billman, legal representative

Patent number: 7997538Abstract: A fan control effector for an aircraft comprises at least one blade configured to be pivotably deployable in a radially outward direction from a retracted position to a deployed position such that the blade extends out of the aircraft. The fan control effector may be mounted in a symmetrical arrangement about a longitudinal axis on opposing wings of the aircraft. Furthermore, the fan control effector may comprise any number of blades for independent deployment outwardly from the wing. The blades are configured to be angularly deployable along a direction that is non-parallel to the longitudinal axis of the aircraft. The blades may be configured to be deployable sequentially from the wing starting with an initial deployment of an aft-most one of the blades.Type: GrantFiled: March 13, 2008Date of Patent: August 16, 2011Assignee: The Boeing CompanyInventors: Bradley A. Osborne, Scott L. Schwimley
