Patent number: 11964266Abstract: A process for removing Co2+, Pb2+, Cd2+ and Cr3+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchange composition to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchange composition. The ion exchange compositions are represented by the following empirical formula: AmZraTibSncMdSixOy. A composition comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution is also disclosed. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.Type: GrantFiled: July 9, 2019Date of Patent: April 23, 2024Assignee: UOP LLCInventors: Gregory John Lewis, Paulina Jakubczak, Julio C. Marte, William Christopher Sheets

Patent number: 10611573Abstract: A flexible composite conveyor belt, such as for use as a belt wrapper in overlying combination with a metal belt in cooking or heating operations. The belt includes a protrusion attached to a flexible substrate. The protrusion includes an engagement surface adapted to secure the protrusion to a portion of the underlying metal belt to drive the belt at a same speed as the conveyor belt. Protrusions on opposing ends of the belt negate the need for conventional lacing in securing the ends of the belt together.Type: GrantFiled: September 13, 2017Date of Patent: April 7, 2020Assignee: ADVANCED FLEXIBLE COMPOSITES, INC.Inventors: William James Lewis, Marc W.

Publication number: 20190062959Abstract: A fabricated part for a high temperature operation including a non-metallic substrate formed of a polymer fabric of woven non-absorbent polymer filament. The substrate is heat-resistant and heat set at a temperature that is above a predetermined operating temperature of an operation of the fabricated part. The heat setting pre-shrinks/heat stabilizes the material, thereby reducing failure during use in high temperature and/or wet applications. The substrate is useful as an endless belt and other applications. The invention further includes an apparatus with a heating device configured to operate at the predetermined operating temperature, and the fabricated part within or extending through the heating device.Type: ApplicationFiled: August 29, 2018Publication date: February 28, 2019Applicant: ADVANCED FLEXIBLE COMPOSITES, INC.Inventors: William Christopher Lewis, Barton Roy LEWIS, William James LEWIS

Patent number: 8857652Abstract: A food support for holding food items during cooking in an oven. The food support includes a reinforcement structure including a perimeter frame extending around and defining a substrate placement area. At least one cross bar extends between two opposing portions of the support frame and beneath the substrate placement area. A removable and replaceable substrate insert is sized to be placed on the substrate placement area for receiving food items thereon. A securing element can be connected to the reinforcement structure for securing the substrate insert on the substrate placement area. A holding device including a holding surface connected to a clamping element, where the holding surface is adapted to support a bottom of the food support and the clamping element is adapted to clamp over a top surface of the food support, can be used to securely introduce and/or remove the food support from an oven.Type: GrantFiled: April 18, 2013Date of Patent: October 14, 2014Assignee: Advanced Flexible Composites, Inc.Inventors: William James Lewis, Marc W.

Patent number: 7470453Abstract: A method for forming a flexible composite useful for forming belts that are processed into pressure sensitive tapes or converted into rolled goods. The method impregnates a flexible substrate with a polymer coating that includes a thermoplastic or thermoset resin that is not a fluoropolymer. The impregnating coating layer may also include a fluoropolymer. Additional fluoropolymer polymer overcoating layers are applied to the impregnating layer to form the flexible composite. The coating layers are applied as a liquid and dried.Type: GrantFiled: October 11, 2005Date of Patent: December 30, 2008Assignee: Advanced Flexible Composites, Inc.Inventors: William Christopher Lewis, William James Lewis, Steven Fuessle, Marc W.
