Patent number: 8468839Abstract: A portable liquid oxygen (PLOX) unit and method of filling. The LOX unit includes a LOX container. An inlet line communicates LOX from a LOX supply to an the LOX container, and an outlet line communicates LOX from the LOX container ultimately for consumption by a user. A vent line communicate the interior of the LOX container to ambient atmosphere. A vent valve is coupled to the vent line to selectively communicate the LOX container to the ambient atmosphere. An auto shutoff assembly is associated with vent line to substantially block the vent line when the LOX in the LOX container reaches a predetermined level. A reset element associated with the auto shutoff assembly causes at least a portion of the auto shutoff assembly to unblock the vent line for subsequent filling.Type: GrantFiled: January 23, 2008Date of Patent: June 25, 2013Assignee: RIC Investments, LLCInventors: Douglas Whitcher, Robert J. Maddox, Jr., Joseph T. Dolensky

Patent number: 8167988Abstract: A multi-chamber canister for a pressure swing absorption system within a general housing assembly. The chambers include a first molecular sieve chamber for receiving a first molecular sieve for separating air from the ambient environment into a concentrated gas and at least a second molecular sieve chamber disposed within the housing assembly for receiving a second molecular sieve for separating air from the ambient environment into a concentrated gas component. Furthermore, a supply chamber is disposed within the housing for receiving air from the ambient environment and for communicating air to either first or second molecular sieve chambers.Type: GrantFiled: March 8, 2011Date of Patent: May 1, 2012Assignee: Ric Investments, LLCInventors: Joseph T.

Patent number: 7153107Abstract: A muffler assembly for a compressor that suppresses noise that would otherwise escape from the inlet of the compressor during its operation. The muffler assembly includes an intake conduit that has an inlet portion, an outlet portion adapted to couple to an inlet of a compressor, a longitudinal axis defined between the inlet portion and the outlet portion, and a passage defined through the intake conduit generally parallel to the longitudinal axis. A baffle is disposed in the intake conduit generally traversing the passage. The baffle is defined in a plane that is disposed at an angle with respect to the longitudinal axis. An opening is defined at least partially by the baffle and disposed generally proximate to the outlet portion of the intake conduit.Type: GrantFiled: October 1, 2004Date of Patent: December 26, 2006Assignee: RIC Investments, LLCInventor: Robert J.
