Patent number: 8535412Abstract: The present system is an adsorption system for separating air into a concentrated gas component, which has an air supply, a compressor for receiving and compressing the air supply, providing a compressed air supply, and molecular sieve material for separating the compressed air supply into a concentrated gas component. The adsorption system delivers at least 5 liters per minute (LPM) of concentrated gas component from the molecular sieve material in which the system has a specific total weight per LPM <9 lbs/LPM. Additionally, an output quantity of the concentrated gas is delivered by the adsorption system and a purging quantity of the concentrated gas is dispensed into a sieve chamber of the adsorption system undergoing a purge cycle. The purging quantity has a value equal to or less than the difference between the maximum quantity and the output quantity, and the purging quantity is controlled based on the output quantity.Type: GrantFiled: July 15, 2010Date of Patent: September 17, 2013Assignee: RIC Investments, LLCInventor: Joseph T. Dolensky

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. Dolensky, Robert J. Maddox, Jr., Robert W. Murdoch
