    摘要： Water-soluble copolymers which comprise, in copolymerized form, (a) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I H2C═CR1—X—YR2—OnR3   I  in which the variables have the following meanings:  X is —CH2— or —C(O)—, if Y is —O—; is —C(O)—, if Y is —NH—; is —O— or —O—(CH2)4—, if Y is a chemical bond;  Y is —O—, —NH— or a chemical bond;  R1 is hydrogen or methyl;  R2 is C2-C4-alkylene radicals, which may be identical or different and also linear or branched, but where at least 50% of the radicals R2 are ethylene;  R3 is C1-C22-alkyl, phenyl, p-(C1-C12-alkyl)phenyl or hydrogen;  n is an integer from 6 to 50, (b) 1 to 40% by weight of at least one nonquaternized dipolar monomer comprising at least one nitrogen atom, (c) 0 to 39% by weight of other nonionic monoethylenically unsaturated monomers and (d) 0 to 10% by weight of other anionic monoethylenically unsaturated monomers and have an average molecular weight Mw of from 2000 to 500 000 D, and the use of the copolymers as dispersants and sequestrants for pigmented materials, as additive for detergents, laundry pretreatment compositions, cleaners for hard surfaces, dentifrices and bodycare compositions, and as auxiliaries for textile processes, paper making and paper processing and deinking processes.

    摘要： Methods, systems and computer program products provide communications with a plurality of application instances using a plurality of communication protocol stacks and a single Internet Protocol (IP) address. A stack is established as a routing stack associated with the single IP address. Other stacks which are associated with the single IP address are defined as candidate target stacks and an identification of candidate target stacks and the routing stack is distributed to the stacks. The routing stack is notified when an application associated with a candidate target stack listens to a port of the IP address to establish a current actual target stack. A request to establish a connection to the IP address and the port of the IP address is received and a routing table entry corresponding to the current actual target stack is created to provide a routing path from the routing stack to the current actual target stack. Communications to the port of the IP address received by the routing stack are routed based on the routing table.

    摘要： Biodiesel fuels are produced efficiently and at low cost from waste oil feeds containing high concentrations of fatty acids. By first producing an ester of a water immiscible alcohol, water of reaction from the esterification can be easily stripped out with and separated from the alcohol, which is recycled to the esterification reaction. Subsequent transesterification with glycerin produces a feed with a sufficiently low acid value to allow methanolysis using a basic catalyst to proceed rapidly without consumption of large quantities of catalyst or organic acid salt formation.
