Abstract:
A system is provided for creating and/or collecting, storing and providing access to data from an electric power device which contains a cooling or operating liquid. A sensing device is mounted on the electric power device. The sensing device includes a microprocessor/microcontroller, a memory, a display panel, an input panel, and a tag read/write apparatus. A sampling container for holding a liquid sample to be taken from the electric power device has a container tag mounted thereon. The tag read/write apparatus uses a wireless communication link, when a sample has been taken, to transmit (i) administrative data denoting the electric power device, and (ii) diagnosis data denoting the sample taken to the container tag. The diagnosis data can be input directly using the input panel of the sensing device when a sample has been taken.
Abstract:
The present invention is directed to a process for the isolation of tris(2,3-dibromopropyl)isocyanurate. The process uses an adsorbent which promotes easy conversion into a solid form of TDPI. The invention also includes to the solid TDPI product prepared in this way and its use in providing flame retardancy to plastics.
Abstract:
Powdered mixtures of chlorhexidine base with selected sugar acids or lactones from the group gluconic acid or gluconolactone, lactobionic acid (I), D-galactono-&ggr;-lactone (II), L-mannono-&ggr;-lactone (III), D-(−)-gulono-&ggr;-lactone (IV), D-(+)-galacturonic acid (V) and &agr;-D-heptaglucono-&ggr;-lactone (VI). The formulations have extraordinary storage stability. New chlorhexidine salts with sugar acid anions based on (I) to (VI) and aqueous solutions of these are also described. The formulations, solutions and pure salts are used as disinfectants and to prepare disinfectants.
Abstract:
A process for preventing the transfer of harmful organisms of zooplankton including the epifauna thereof and of phytoplankton including its resting stages, which are taken up with the ballast water of ships and transferred to another locality on discharge. The organisms are substantially destroyed by the addition of an agent containing a water-soluble percarboxylic acid with 1 to 6 carbon atoms, particularly an aqueous solution containing peracetic acid and/or performic acid and hydrogen peroxide, in a quantity of 0.1 to 200 mg of percarboxylic acid per liter of ballast water and allowing it to react before discharge. In a preferred embodiment, cyanide is also added to the ballast water.
Abstract:
Acrolein polymer from acrolein and one or more polyhydric alcohols, characterized by release of monomeric acrolein in aqueous systems and hence by a prolonged effect on microorganisms, is prepared by adding acrolein to a reaction medium containing catalyst in dissolved form, and not allowing the temperature of the reaction medium to rise about 50.degree. C. The acrolein polymer may be used in aqueous systems as a biocide.
Abstract:
Algicides are added to water for the algicidal treatment of the water, especially swimming-pool water. The disadvantages of known methods can be avoided or reduced if chlorohexidine or a salt thereof is used as algicide. Chlorohexidine and its salts are distinguished by a broad spectrum of algicidal action at very low concentrations of use.
