Patent number: 11065585Abstract: The present invention relates to synthetic membranes and use of these synthetic membranes for isolation of volatile organic compounds and purification of water. The synthetic membrane includes a hydrophobic polymer layer located on a polymeric membrane support layer. The invention includes a method of isolating volatile organic compounds with the synthetic membrane by contacting a volatile organic mixture with the hydrophobic polymer layer of the synthetic membrane and removing volatile organic compounds from the polymeric membrane support layer of the synthetic membrane by a process of pervaporation. The invention also includes a method of purifying water with the synthetic membrane by contacting an ionic solution with the hydrophobic polymer layer of the synthetic membrane and removing water from the polymeric membrane support layer of the synthetic membrane by a process of reverse osmosis. The invention also relates to methods of isolating non-polar gases by gas fractionation.Type: GrantFiled: July 29, 2020Date of Patent: July 20, 2021Assignee: Rensselaer Polytechnic InstituteInventors: Georges Belfort, Joseph Grimaldi, Joseph Imbrogno, James Kilduff, John Joseph Keating

Publication number: 20060232029Abstract: A stackable refuse cart includes a container, an axle, a set of wheels. The container includes first and second axle supports. The first axle support supports the axle in an operative position to rotatably support the container. The second axle support supports the axle in a stowage position enabling the container to be stacked with other containers without interference from the axles. In one embodiment, the second axle support includes a recess defined in the floor of the container. In another embodiment, the second axle support includes a pair of supports that hold the axle against a sidewall within the container. In yet another embodiment, the second axle support is a cradle integral with the container handle.Type: ApplicationFiled: April 14, 2005Publication date: October 19, 2006Inventors: Brian Parker, Mariano Acosta, James Kilduff, Joseph Bollo
