Patent number: 6913637Abstract: An air purifier includes a main body defining an air passage therein to allow sucked air to pass therethrough prior to being discharged, and a first filter installed in the main body to be switched between a closed state and an open state. The first filter removes contaminants from the sucked air in the closed state, and allows the sucked air to pass through the air passage in the open state. The air purifier may include a main body to suck and discharge air, with a bypass passage formed in the main body so that the bypass passage is opened or closed by a door, and a first filter installed in the main body. The sucked air passes through the first filter prior to being discharged when the door is closed, and passes through the bypass passage prior to being discharged when the door is opened.Type: GrantFiled: June 3, 2003Date of Patent: July 5, 2005Assignee: Samsung Electronics Co., Ltd.Inventor: Jung-Ho Kim

Patent number: 6890376Abstract: The present invention provides a gas purification system with improved efficiency, simpler construction, cost reductions, form factor improvements, and increased durability. The present invention provides cost and form factor improvements through fewer components overall and through utilizing multiple integrated components. Prior art gas purification systems are more bulky and complicated. The present invention achieves increased thermal efficiency through utilization of a regenerative heat exchanger to recapture a portion of the heat energy transferred to the gas during the purification process. Prior art purifiers lacked a regenerative heat exchanger. The present invention integrates the two components into one integrated heater and purification vessel assembly. The present invention integrates the two discrete components into one integrated hydrogen sorption and particle filter assembly. The integrated hydrogen sorption and particle filter assembly is also capable of operating at higher temperatures.Type: GrantFiled: June 26, 2003Date of Patent: May 10, 2005Assignee: SAES Pure Gas, Inc.Inventors: Pierre J.

Patent number: 6840982Abstract: A storage device for the preservation of oxidizable materials is provided. The storage device includes a storage chamber enclosing a storage space where oxidizable materials may be placed and a differentially permeable membrane. The differentially permeable membrane allows at least one selected gas to pass therethrough while inhibiting at least oxygen from passing therethrough. The differentially permeable membrane is in fluid communication with the storage chamber such that the at least one selected gas is allowed to pass through the differentially permeable membrane flows into the storage chamber. An air mover, preferably a compressor, feeds gases to the differentially permeable membrane. A cooling element is provided for cooling the temperature within the storage chamber below that of the ambient temperature. The level of oxygen within the storage chamber is thus reduced relative to the level of oxygen in the atmosphere.Type: GrantFiled: November 8, 2002Date of Patent: January 11, 2005Assignee: American Moxie, LLCInventors: Lawrence Kunstadt, Peter Carlson
