Patent number: 11982185Abstract: A barrier assembly used in the protection of personnel at worksites and/or residential areas from escapes of gas. Such a barrier assembly controls the lateral and vertical spread of gas in the event of an escape of the gas, even more particularly toxic gas. The barrier assembly can be used at operating sites where gases are produced, and in particular where high concentrations of toxic gases (e.g. CO2, H2S, SO2, mercaptans etc.) are present. The barrier assembly can, optionally act as a safety system in the event of an accidental uncontrolled release of these toxic gases into the atmosphere.Type: GrantFiled: February 13, 2020Date of Patent: May 14, 2024Assignee: ENI S.P.A.Inventors: Luca Decarli, Laura La Rosa, Alberto Renato De Angelis, Andrea Vignali

Patent number: 11982186Abstract: A vapor powered electro-mechanical generator comprises a cylinder, which is sealed at both ends in which two pistons slidingly move in opposite directions simultaneously. A tube on which the pistons also slide lies at the center of the longitudinal axis of the cylinder. The tube transfers vapor from the inlet to the pressurized side of the pistons to actuate pistons, while one or more exhaust valves are simultaneously opened on the opposite end of the piston stroke allowing the expanded vapor to flow to a condensing system. The pistons consist of magnets at their peripheral circumference. As the vapor expands, the pistons magnets move through coils of conductive wire producing electric current. Further, repulsion magnets repel corresponding piston magnets to provide a cushioned rebound effect while conserving momentum of the generator.Type: GrantFiled: December 13, 2022Date of Patent: May 14, 2024Inventor: Walter B.
