20110232482 | Moisture Mitigation in PSA Air Fractionation - Disclosed is a method for subjecting feed air to fractionation for recovery of a product oxygen fraction therefrom in a pressure swing adsorption (PSA) process utilizing a nitrogen-selective adsorbent (“NSA”) that is sensitive to water. The PSA process includes the steps of feed pressurization, production, equalization, and blowdown. The improvement to this PSA process commences with placing a bed of pre-treatment adsorbent between feed air and a bed of NSA. Next, a controllable valve is interposed between the pre-treatment adsorbent bed and the NSA bed. Finally, the controllable valve is kept closed during the steps of production, equalization, and when the process is idle. An advantageous NSA is LiX zeolite, Li-LSX zeolite, CaX zeolite, and similar adsorbents, particularly highly hydrophilic zeolites. Another feature of the disclosed PSA cycle is that the pre-treatment adsorbent bed blows-down while the NSA bed equalizes. | 09-29-2011 |

20140338529 | MEDICAL/SURGICAL SMOKE EVACUATOR THAT CONTINUALLY DRAWS WASTE INTO THE EVACUATOR TO CONTROL THE OPERATION OF THE EVACUATOR - A smoke evacuator that draws smoke generated during a medical surgical procedure away from the site at which the smoke is generated. The smoke evacuator includes a pump that draws air into a filter. A sensor internal to the filter monitors the smoke in the air stream drawn through the filter. Normally the pump runs at a low speed, a speed sufficient to draw some air in the filter. When the sensor detects the presence of an appreciable amount of smoke in the air stream the sensor sends a signal indicating the air stream is in this state to the pump controller. The controller then increases the pump speed to result in a like increase in the volume of air drawn through the smoke evacuator. Since the sensor is contained in the filter, a new sensor is installed in the system each time a new filter is installed. | 11-20-2014 |
