IPC: A61K31/739
Filed: 2002-03-28
Granted: 2013-07-09
Abstract: Herein is disclosed a method for producing lipopolysaccharide (LPS), comprising: (a) growing a culture of a deep rough mutant bacterial strain in a medium; (b) maintaining the culture in stationary phase for at least about 5 hr; (c) harvesting cells from the culture; and (d) extracting LPS from the cells. The method allows for the production of an LPS which can be used to produce a 3-O-deacylated monophosphoryl lipid A (3D-MLA) having at least about 20 mol% of the hexaacyl congener group. Also herein is disclosed a method of extracting lipopolysaccharide (LPS) from a culture of deep rough mutant bacterial strain cells, comprising: (a) extracting the cells with a solution consisting essentially of at least about 75 wt% of an aliphatic alcohol having from 1 to 4 carbon atoms and the balance water, thereby producing cells with reduced phospholipid content; and (b) extracting the cells with reduced phospholipid content with a solution comprising chloroform and methanol, thereby yielding a solution of LPS in chloroform and methanol (CM). This method provides LPS solutions in CM that have reduced phospholipid content and are produced by relatively simple and inexpensive process steps.

Patent CA-2484417-C (CA)
Inventor: SMOLINSKY DAVID
IPC: F25B13/00
Filed: 2001-05-07
Granted: 2009-07-07
Abstract: An improved reverse-cycle heat pump system (100) is disclosed that comprises components to improve the efficiency of the system in the cooling mode.  Specifically, the invention incorporated a conduit assembly (50) for carrying refrigerant from one heat exchanger to the other heat exchanger, wherein the heat exchangers (20) are configured to function interchangeably as a condenser and evaporator, depending upon whether the system is operating in cooling mode or heating mode. The conduit assembly (50) includes a coiled section (53) of tubing disposed near the heat exchanger that functions as an evaporator (20) in cooling mode. This coiled section functions as a reservoir for collecting excess refrigerant liquid from the "evaporator" during operation of the system in the cooling mode. Consequently, in cooling mode, heat dissipation via the condenser is thereby increased since less refrigerant liquid is contained therein, resulting in improved cooling of the conditioned area or substance.

Title: Fraud detection mechanism adapted for inconsistent data collection
Inventor: RYAN FREDERICK W JR
IPC: G07B17/04
Filed: 2005-07-27
Granted: 2011-03-29
Abstract: Fraud detection mechanisms and methods that are adapted for inconsistent data collection are provided. Data is analyzed to determine normal operational variations from ideal system behavior. Profiles are developed for each individual sender, e.g., the number of multiple scans performed per confirmation number generated by each sender, and other parameters, such as delivery areas, e.g., the number of multiple scans performed per specific geographic area. If the sender's profile differs significantly from the normal operational variations, there is an indication of potential fraudulent activity and an investigation can be initiated. By analyzing a combination of sender and delivery scan data with system wide scan data, the effect of inconsistent data is minimized to significantly reduce the number of erroneous indications of fraudulent activity while still providing a high level of fraud detection.
