20100075827 | CATALYTIC NANOPOROUS MEMBRANES - A nanoporous catalytic membrane which displays several unique features Including pores which can go through the entire thickness of the membrane. The membrane has a higher catalytic and product selectivity than conventional catalysts. Anodic aluminum oxide (AAO) membranes serve as the catalyst substrate. This substrate is then subjected to Atomic Layer Deposition (ALD), which allows the controlled narrowing of the pores from 40 nm to 10 nm in the substrate by deposition of a preparatory material. Subsequent deposition of a catalytic layer on the inner surfaces of the pores reduces pore sizes to less than 10 nm and allows for a higher degree of reaction selectivity. The small pore sizes allow control over which molecules enter the pores, and the flow-through feature can allow for partial oxidation of reactant species as opposed to complete oxidation. A nanoporous separation membrane, produced by ALD is also provided for use in gaseous and liquid separations. The membrane has a high flow rate of material with 100% selectivity. Also provided is a method for producing a catalytic membrane having flow-through pores and discreet catalytic clusters adhering to the inside surfaces of the pores. | 03-25-2010 |

20090064690 | System and method for cryogenic enhancement to mechanical freezers - A cryogenic enhanced mechanical freezer system and method are provided. The disclosed system includes a mechanical freezer compartment adapted for freezing food products, a cryogen injection system adapted to directly inject cryogen into the mechanical freezer compartment, an exhaust system adapted to rapidly evacuate cryogen vapors from the freezer compartment; and a freezer control system adapted to operatively control the exhaust system and cryogen injection system in response to selected inputs. The selected inputs may include user inputs as well as inputs received from a temperature sensor disposed in the freezer compartment and a gas analyzer adapted to monitor concentrations of selected gases within the freezer compartment. Access to the freezer compartment is prevented during cryogen injection and when the atmosphere in the freezer compartment is not safe as determined by the gas analyzer. | 03-12-2009 |
20090090112 | SYSTEM AND METHOD FOR CRYOGENIC ENHANCEMENT TO MECHANICAL FREEZERS - A cryogenic enhanced mechanical freezer system and method are provided. The disclosed system includes a mechanical freezer compartment adapted for freezing food products on a conveyor, a cryogen injection system adapted to directly inject cryogen into a shrouded zone proximate the conveyor in the mechanical freezer compartment, an exhaust system adapted to rapidly evacuate cryogen vapors from the freezer compartment; and a freezer control system adapted to operatively control the exhaust system and cryogen injection system in response to selected inputs so as to not adversely affect the mechanical refrigeration capacity associated with the mechanical freezer. The selected inputs may include user inputs as well as inputs received from one or more temperature sensors disposed in the freezer compartment and a gas analyzer adapted to monitor concentrations of selected gases within the freezer compartment. Access to the freezer compartment is prevented using a door interlock arrangement during any cryogen injection operations and when the atmosphere in the freezer compartment is not safe as determined by the gas analyzer. | 04-09-2009 |

20100275250 | ACCOUNT RECOVERY VIA AGING OF ACCOUNT DATA POINTS - Embodiments are directed towards providing an aging of account data points usable in recovering access to an account. The aging functionality of account data points is configured to enable users who may have had access to their account compromised or otherwise denied, still be able to recover access. Account data points are time stamped when associated with an account. When a request is received to delete the account data point, the account data point is instead placed into an aging status for a time period. During the aging status time period, the account data point may still be used to recover access to the account. Moreover, after access is recovered using a certain account data point, any account data points created after the certain account data point may be deleted to minimize unauthorized access to the account. | 10-28-2010 |
