Title: Pressure swing adsorption process
Inventor: KUZNICKI STEVEN M
IPC: C10L3/10
Filed: 2002-02-15
Abstract: A pressure swing adsorption process for the separation of nitrogen from a mixture of same with methane, utilizing two separate PSA stages, one containing a nitrogen selective adsorbent and the second containing a methane-selective adsorbent. In the process, the first PSA unit containing a nitrogen selective adsorbent forms a product methane stream and a waste stream rich in nitrogen which is passed to a second PSA unit containing a methane selective adsorbent which forms a product nitrogen stream and a waste stream rich in methane. The waste stream rich in methane can be treated to remove heavy hydrocarbons therefrom before the methane is recycled to feed.

Title: Organising data in a database
Inventor: PAULY DUNCAN G
IPC: G06F17/30
Filed: 2002-02-19
Abstract: A database is provided in which conclusion sets (20, 22, 24, 26, 28 and 30) are divided into a hierarchical series of levels (level 1, level 2, level 3) . Data is added to a conclusion set at the first level (level 1) until such ti me as that conclusion set is full. Data is then migrated from the conclusion se t (20) to its subordinate conclusion sets (24, 26) therefore reducing the amou nt of disc access required to add data to the database since multiple entries a re migrated in relatively few disc access operations.

Patent CA-2455030-A1 (CA)
Inventor: DREWNO GREGORY
IPC: C09D5/03
Filed: 2002-07-26
Abstract: The present invention is directed to a powder coating composition and a method. The method improves the color strength of a cured film of the powder-based coating composition. To produce the powder-based coating composition, the method begins by combining a powder-based binder, specifically a resin and a cross-linking agent,with a pigment and a surfactant to form a mixture. The mixture is then extruded thereby forming an extrudate of the mixture. The extrudate is cooled and then ground to produce the powder-based coating composition from the extrudate of the mixture. Next, the powder-based coating composition is spray applied to a substrate and cured to form the cured film.  The surfactant in the mixture improves the color strength of the powder-based coating composition and the cured film so that the amount of pigment included in the mixture can ultimately be reduced. Additionally, certain physical properties of the cured film are not compromised.

Title: A system for reducing noise in an implantable medical device
Inventor: STOEBEL JOHN C
IPC: A61N1/372
Filed: 2002-09-04
Abstract: A system and method for reducing the amount of noise causes by inductive elements within an implantable medical device. In particular, the invention provides a system for gradually initiating and terminating the current flow within inductive elements such as transformers that are used to charge energy storage devices such as high-voltage capacitors of an implantable cardio/defibrillator. This more gradual change in the rate of current flow prevents ground shifts and subsequent noise spikes within the device. This, in turn, allows cardiac signals to be sensed more accurately by sensing circuits, preventing oversensing, and minimizing the occurrence of inappropriate shock delivery.

Abstract: The invention is a radiation curable coating containing an antimicrobial agent, where upon irradiation with UV light, the radiation curable coating rapidly cures to a polymeric coating. The polymeric coating has durable antimicrobial properties, being especially effective at preventing the growth of Staphylococcus aureaus and Kleibsella pneumoniae on wood flooring and furniture. The major components in the radiation curable coating are a urethane acrylic oligomer, a radiation cure package, an antimicrobial agent, a cross-linking agent, and optionally, an additive package. The radiation curable urethane oligomer is a relatively short chain backbone urethane polymer that is end capped with a radiation curable moiety, where the moiety is an acrylic. The cross-linking agent is one or more monomers used to lower the viscosity and promote cross-linking, and include acrylate esters of mono-, di-, tri-, or tetrafunctional alcohols. The radiation cure package contains at least one photoinitiator.

Title: Improved label for stretch wrapped stacks
Inventor: SCHMELZER WINFRIED
IPC: G09F3/10
Filed: 2002-09-30
Abstract: The present invention relates to labels which are adhesively attached to the outside of a stack of packages or articles which packages or articles are combined on a pallet typically by a stretch wrapped film. Such stretch wrapped stacks are highly stable but due to the stretch in the film used for holding the stack together and depending on the compressibility of the packages or articles, the stack will shrink by a certain amount during further handing and shipment. Such stretch wrapped stacks are usually provided with labels, which have to allow the stretch wrapped stack to shrink and be deformed to a certain extent during handing and shipment. The present invention relates to labels, which are designed, to achieve a substantial improvement in stability after having been applied to a stretch wrapped stack of packages or articles.

Filed: 2002-10-17
Abstract: Apparatus and methods for compressing data points. The invention compresses the representation of a sequence of points in a space by, for example, dividing the sequence of points into segments of successive points and then compressing each of the segments irrespective of the compression applied to the other segments. The dividing may include dividing the points sequence into segments of S successive points. The value of S may be the value of S  generating the smallest of the multiple compressions. The compression may include compressing each of the segments of S successive, i-bit points into segments of j-bit points, where j <= i, j may vary from segment to segment and, for any given segment, j is the minimum number of bits necessary to represent the data in that given segment.

Abstract: Several studies have demonstrated that bovine whey produced by cheese maker industry contains several bioactive factors promoting health and preventing disease. Although many efforts have been made over the years to show that immunoglobulins, lactoperoxidase, lactoferrin, lysosyme and small peptides present in whey have antimicrobial activities against several pathogenic microorganisms, such activity has not been investigated so far for the lipid fraction of whey. There, is disclosed a method of inhibiting the germination of Candida albicans using free fatty acids derived from whey cream. Further fractionation by HPLC demonstrates that this activity can be mainly attributed to lauric, myristoleic, linoleic and arachidonic acids.
