20110017063 | APPARATUS FOR SEPARATING OXYGEN FROM AMBIENT AIR - An apparatus for separation of gases from ambient air that has at least one separation column with an inlet at a first end and an outlet at a second end, a buffer column having a single inlet at a first end, a vacuum pump, and a valve system that connects the vacuum pump to the outlet at the first end of the separation column, and that connects the outlet at the second end of separation column to the single inlet at the first end of the buffer column. | 01-27-2011 |
20110017216 | METHOD OF SEPARATING AND DISTRIBUTING OXYGEN - Disclosed is a method of providing oxygen rich gas. Oxygen is separated from ambient air with an oxygen separator in discrete pulses, one pulse at a time. The start of the pulse is synchronized with the beginning of an inhalation of a person. The oxygen rich gas in each pulse is separated from the ambient air in real time during a nitrogen adsorption step concurrent with each inhalation. | 01-27-2011 |
20110197890 | AMBULATORY OXYGEN CONCENTRATOR - An oxygen concentrator provides ambulatory oxygen utilizing a vacuum swing adsorption (VSA) oxygen separator powered by a power pack. The separator has a plurality of nitrogen-selective adsorbent beds, each operating in VSA cycles including feed, evacuation and repressurization phases. The concentrator also contains a delivery system for receiving oxygen produced by the VSA separator. | 08-18-2011 |
20130036910 | APPARATUS FOR SEPARATING OXYGEN FROM AMBIENT AIR - An apparatus for separation of gases from ambient air that has at least one separation column with an inlet at a first end and an outlet at a second end, a buffer column having a single inlet at a first end, a vacuum pump, and a valve system that connects the vacuum pump to the outlet at the first end of the separation column, and that connects the outlet at the second end of separation column to the single inlet at the first end of the buffer column. | 02-14-2013 |
20130145933 | APPARATUS FOR SEPARATING OXYGEN FROM AMBIENT AIR - An apparatus for separation of gases from ambient air that has at least one separation column containing an adsorbent with an inlet at a first end and an outlet at a second end, a buffer column containing an adsorbent and having a single inlet at a first end, a vacuum pump, and a valve system that connects the vacuum pump to the outlet at the first end of the separation column, and that connects the outlet at the second end of the separation column to the single inlet at the first end of the buffer column. | 06-13-2013 |
