Abstract: A method of treating the surfaces of medical instruments which are contaminated with prions includes contacting the surface with a composition containing a source of peroxide ions, such as hydrogen peroxide, at a molar concentration of at least 1.5M peroxide (equivalent to approximately 5% hydrogen peroxide) and preferably, about 2M peroxide (approximately 7% hydrogen peroxide). The composition is optionally in the form of a gel. The composition is retained in contact with the surfaces for about 1-2 hours until all or substantially all prion contamination is removed.

Abstract: A low pH disinfectant composition comprises an aqueous composition of a phenolic compound, an organic acid, and/or a dispersing surfactant and/or solvent. The disinfectant solution can be concentrated, or more preferably diluted ready to use, and is very effective in eradicating fungi including Aspergillus niger.

Abstract: A kit for forming a sterile cleaning solution. The kit is comprised of a container, a packet, a first flexible package and a second flexible package. The container contains a liquid and has an opening and a removable cap sealing the opening. The packet contains a pre-measured amount of an active agent. The first flexible package is dimensioned to enclose the container and the packet. The second flexible package is dimensioned to enclose the first flexible package, the container and the packet.

Abstract: A method of decontaminating a surface or liquid which is contaminated with prions includes treating the surface with a composition which includes one or more phenol. Phenols which are particularly effective include p-chloro-m-xylanol, thymol, triclosan, 4-chloro, 3-methylphenol, pentachlorophenol, hexachlorophene, 2,2-methyl-bis(4-chlorophenol), and p-phenylphenol.

Abstract: A method and apparatus for monitoring the concentration of a detergent in a detergent solution. A capacitive sensor is exposed to the detergent solution, and electrical properties of the capacitive sensor are responsive to changes in the concentration of detergent in the detergent solution.

Abstract: A method and apparatus for monitoring the state of a chemical solution for neutralization of chemical and biological warfare agents are disclosed. A capacitor is exposed to the chemical solution, wherein the steam acts as a dielectric between the plates of the capacitor. Permittivity of the dielectric is affected by the oxidant levels in the chemical solution, and thus a measurement of electrical properties of the capacitor is used to monitor the state of the chemical solution.

Abstract: A method and apparatus for monitoring at least one of steam purity and steam quality for steam used in a decontamination process. A capacitor is exposed to the steam, wherein the steam acts as a dielectric between the plates of the capacitor. Permittivity of the dielectric is affected by the purity and/or quality of the steam, and thus a measurement of electrical properties of the capacitor is used to monitor steam purity and/or quality.

Abstract: In a device for producing granules or tablets from fluid materials, the material is fed to the press-slot between a rotative hollow cylinder with an inner toothing and a press-cylinder with an outer toothing that engages the inner toothing. Bores extend from the bottom of the teeth of the inner toothing of the hollow cylinder up to its outer side. The material is pressed through these bores when the hollow cylinder engages the press-cylinder and is laid as tablets or granules on a cooling surface. At least one part of the outer circumference of the hollow cylinder remote from the cooling surface is surrounded by a heating shell. Outside the heating shell and spaced apart from it is arranged another shell in such a way that, between the heating shell and the other shell, a waste gas shaft is formed in communication with a suction nozzle for withdrawing the gases that emanate from the deposited material as it cools.

Abstract: The invention relates to adhesive compositions for gluing wood containing aqueous vinyl ester graft copolymer dispersions and water-soluble acid metal salts or free acids, in which the adhesive compositions exhibit outstanding resistance to hot water and have high storage stability. The vinyl ester graft copolymer comprises from 2 to 12 percent by weight, based on the total weight of the graft copolymer, of one or more polyvinyl alcohols having a degree of hydrolysis of from 60 to 99 mol persent and 88 to 98 percent by weight, based on the total weight of the graft copolymer, of a grafting monomer mixture. The grafting monomer mixture contains from 5 to 50 percent by weight, based on the total weight of the monomer mixture, of vinyl esters of saturated, highly branched aliphatic monocarboxylic acids having 9 or 10 carbon atoms, vinyl pivalate, diisopropyl maleate, diisopropyl fumarate, vinyl chloride and mixtures thereof.

Abstract: An apparatus is disclosed for producing granules or pastils from a flowable material of varying viscosity wherein material is supplied to a pressing nip between a rotating hollow roll (1) having internal teeth and an externally toothed ejection roll (2) in engagement with said hollow roll. Provided in the hollow roll (1) are bores (5) which extend from the respective teeth bottoms of the internal toothing to the outer side of the hollow roll (1) and through which the material is expelled on engagement of the ejection roll (2) and deposited in the form of pastils or granules on a cooling surface (13). On the outer periphery of the hollow roll (1) a jacket tube (3) may be positioned the jacket tube having bores which align with the bores (5) of the hollow roll (1), the jacket bores also having a reduced cross-section compared with the bores of the hollow roll to permit adaption of the apparatus to the viscosity of the flowable material to be processed.

Abstract: A process for the preparation of color-stable levulinic acid by saponification of acetylsuccinates with aqueous mineral acids, by continuously treating the starting products with steam in counter-current in a reactor cascade, the reaction being carried out above the boiling point of the alcohol being formed in the reaction or above the boiling point of the aqueous azeotrope being formed.

Abstract: A new variety of Streptocarpus plant is characterized by its small, narrow and flattened leaves. The plant has bouquet-type flowers standing above the leaf line. The flowers have a flattened appearance due to the flat bottom petals and reflexed top petals.
