Abstract: A multi-lumen catheter is formed by first introducing one end of an expandable tube into the blood vessel. A divider is then inserted into the distal end of the tube and extends the length of the tube, thereby dividing the tube into a plurality of the separate lumens. Insertion of the divider causes radial expansion of the tube which substantially seals the opening in the wall of the vessel. In one embodiment, the divider has a hollow triangular cross-section which creates four separate lumens. A series of raised protrusions extending outwardly from the sides of the divider prevent collapse of the tube against the divider.

Abstract: An apparatus including an assembly associated with a downhole tool configured to thermally isolate a thermally sensitive component. Components of the assembly include an external isolating vessel; a passive thermal barrier encased in the external isolating vessel; at least one electronic component housed within the downhole tool for monitoring geothermal well properties; and at least one thermally sensitive electronics carrier package positioned within the passive thermal barrier comprising thermally sensitive electronic components. The passive thermal barrier ideally comprises an additively manufactured layered labyrinthine shell structure, a plurality of polarly phased centralizers between shell layers and minimal centralizing contact points on its exterior shell, to minimize known heat transfer modes associated with the external isolating vessel.

Abstract: The present invention provides methods for the reduction and recycling of papermaking sludge. Papermaking sludge is incinerated in a rotary heater, typically a rotary cement kiln, asphalt dryer, or specially designed rotary kiln or incinerator. Aggregate may be combined with the sludge to provide better dispersion of the sludge within the heater, and to facilitate heat transfer. Once in operation, the heat of sludge combustion is added to the process heat, resulting in markedly reduced energy requirements. Papermaking sludge is typically fed continuously into said rotary heater while temperatures in the combustion zone are maintained in the range of approximately 800.degree. to 3500.degree. F. During incineration, mixing catalysts (typically casein or soy protein) and wood fibers are burned, while moisture is evaporated. The resulting product consists essentially of carbonate particles which are collected for subsequent use.

Abstract: The invention is directed to a stable catalytic and aqua-activated polyurethane bandage used for orthopedic casting. The bandage has a substrate and an aqua-activated polyurethane prepolymer. The catalyst used to make the prepolymer is .alpha.-(morpholinopolyethoxy)-.beta.-morpholinoethane or the mixture of .alpha.-(morpholinopolyethoxy)-.beta.-morpholinoethane and cocatalyst bis-(2-dimethylaminoethyl) ether. The catalyst in this bandage can be optionally combined with a stabilizing agent, such as ethane-sulfonic acid to form a structurally stable complex. The catalyst of this invention provides an excellent solidification time and significantly prolongs the storage period of the bandage.

Abstract: This invention teaches a computerized method for use in data acquisition and manipulation of two-dimensional patterns in the fields of medicine, astronomy, chemistry, biology and biotechnology. The invention teaches an interactive computerized method for matching visual patterns of polypeptide spots in two-dimensional (2-D) gel electrophoretogram solubilized into polypeptide constituents that are separated by electrophoresis. The computerized method manipulates spot pixel coordinates using staged coordinate transformation techniques on spot markers and unknown study spots to reduce gel preparation distortions and allows a user to produce matching results in a manner that compares the transformed spot data using either a single reference gel or multiple reference gels approach for producing the matching results. The method also includes a spot matching verification step and a step to extract potentially mis-matched spots from reported matching results. The user can also resolve contradictions and perform spot matching analysis using isoelectric focusing (PI), and molecular weight (MW) dimensional separation data.
