Patent number: 11865468Abstract: An activity box includes two pairs of wheels having blind holes, two axles having two ends releasably insertable into the blind holes, and a box defining a space having a defined volume sufficiently large to fit the axles. The wheels include a first magnetically attractable component. The axles include a second magnetically attractable component secured at each end of each axle. The axles have a length spanning a width of the box, which has two pairs of through holes on two opposing sides to accommodate the axles, such that the axles are threaded through the through holes. The two pairs of wheels are rotatably attached to the box by magnetically coupling the first magnetically attractable component to the second magnetically attractable component, such that the activity box is configured to be used as a cart that can be rolled over a surface.Type: GrantFiled: February 18, 2022Date of Patent: January 9, 2024Assignee: Lovevery, Inc.Inventors: Israel David Catz, Jessica Thacher Crolick Rolph, Claire Way-June Liu, Thomas Creason Rigby, Philip Jacob Fouts

Patent number: 5879796Abstract: This invention concerns an organic/inorganic composite in particulate form prepared by spray drying a solution or dispersion comprising an organic polymer and an inorganic glassy polymer precursor under such conditions that the inorganic glassy polymer precursor forms an inorganic glassy polymer to yield the particulate. Such particulates are useful as reinforcing agents for polymers and in monolithic structures prepared by compression of a plurality of said particulates.Type: GrantFiled: August 8, 1997Date of Patent: March 9, 1999Assignee: E. I. du Pont de Nemours and CompanyInventor: Israel A. David
