Abstract: An imaging method for a catheter having a heart model, the heart model being installed in a container in a state of having the container filled with a liquid, and being provided with coronary arteries and an aorta. The imaging method includes causing a chemical reaction between an injection agent injected into the coronary arteries through a catheter, and the liquid in the container, and changing the color of the injection agent to the same color as that of the liquid.

Abstract: The present invention relates to a fire resistant material comprising a matrix of thermosetting elastomeric resin of the silicone resin type wherein endothermic fillers are incorporated as well as to a high pressure storage tank coated with said material, processes for the preparation thereof and uses thereof.

Abstract: A method is presented for providing a medical device with antibacterial activity, whereby a substrate material coated with a hydrophilic polymer is provided, the hydrophilic polymer exhibiting a low friction when wetted; also provided is a colloidal solution comprising chemically reduced particles of an oligodynamic metal and a hydrophilic polymer, the hydrophilic polymer being the same as in the coating of the substrate material; and the step of dipping the substrate material in the solution. A medical device prepared accordingly is also provided.

Abstract: Composite materials that are palatable to a wood-destroying pest species and also pesticidal to the pest species can be used in pest control devices and can be used as wood substitutes for structural components, which are resistant to destruction by wood-destroying pests. The composite materials include a thermoplastic polymer, a food material for the pest and a pesticide. The composite material is formed by mixing a thermoplastic polymer, wood fragments or other cellulosic materials and a quantity of pesticide, and thereafter creating a molten material within a mixer, compounder, extruder or the like. The molten material is extruded or molded to form the desired shape.

Abstract: A process in which an at least partially delignified pulp fiber web having a Kappa number of less than about 130 is treated with an aqueous endothermic fire retardant solution having a pH of about 10 or less. The treated pulp fiber web has a near neutral pH of from about 5 to about 9, and is treated with at least about 20 lbs of endothermic fire retardants per ton of the pulp fiber web, with at least about 5% of the total amount of endothermic fire retardants being added at a point prior to when the pulp fiber web is formed. Also a fire resistant pulp fiber web having a near neutral pH.

Abstract: Flowable concrete mixtures have an aqueous foam admixture mixed therein to give the concrete mixture desired strength, flowability, and density. The concrete mixtures include a hydration stabilizer to stabilize the aqueous foam. The hydration stabilizer inhibits the reaction between the hydraulic cement and the water in the aqueous foam. The aqueous foam can be stabilized using a fluorochemical surfactant.

Abstract: A composition of matter and a solvent system for use in providing a water resistant coating to a surface of a roof is disclosed. The solvent system comprises a chlorinated solvent blend which includes a vegetable oil. The solvent system and coating composition are non-flammable, environmentally friendly and provide an improved, consistent coating when applied to the surface of a roof.

Abstract: This invention concerns a thermosetting resin system that is useful in the manufacture of high performance prepreg, laminate and composite materials as well as the prepregs, laminates and composites made from the thermosetting resin composition.

Abstract: A method for preserving wood which comprises contacting the wood with a complex of a cationic monomeric or polymeric biocide and an anionic monomeric or polymeric biocide. Insoluble complexes may solubilized in water in the form of an emulsion or microemulsion by adding a nonionic and/or amphoteric surfactant and/or aqueous cosolvent to the complex. Suitable cationic biocides are those that contain functionalities such as amidine, guanidine, biguanide, quaternary, phosphonium, sulfonium and gemini quaternary functionalities. Suitable anionic biocides include: phenolics; saturated, unsaturated or substituted carboxylates; organomercaptide; tetrathiocarbonates; cyanodithioimidocarbamates; dithiodialkylcarbamates; anionic oxides of transition metals; aminocarboxylic acids; aminoorganophosphonic acids; monoalkyl phosphates; dialkylphosphates; and substituted or unsubstituted 2-hydroxy-2,4,6-cycloheptatrianone.

Abstract: Methods that apply decorative particles in-line in the manufacturing process to form a decorative structured mat or veil that is ready for direct commercial application. The decorative particles or decorative paint patterns should be of a size and/or color to be visible at a distance of five meters from the decorative mat or veil. In preferred embodiments, the particle size ranges from about 100 to about 500 microns in size. A formulation for coating a glass fiber mat with decorative particles is also provided.

Abstract: A water-based foam fire extinguisher excellent in foaming properties and film-forming properties in a low temperature region which includes an aqueous solution of at least one member selected among potassium hydrogen carbonate, ammonium phosphate, ammonium sulfate, ammonium bromide, boron oxide, and potassium tetraborate and, incorporated in the solution, a freezing point depressant so as to have a freezing point of −20° C. or below, characterized by containing a perfluoroalkylbetaine as a fluorochemical surfactant and one or more amide-amino acid type surfactants represented by general formula (1) and/or (2) (wherein R1 represents C7-23 alkyl, hydroxyalkyl, aralkyl, or alkenyl; and X represents an alkali metal or hydrogen) as hydrocarbon surfactants.
