Abstract: A computer system may create version records in a versioned database that stores data from transaction documents. Each version record may include a timestamp that represents a time from which the data stored in the version record is valid. The timestamp may represent the time of creation of particular version of the transaction document. The version records may be accessed to perform a valuation for a specified time.

Abstract: A message may be used to update computing system of a commodity transaction. The message may include a commodity identifier, a date term, a quantity term, and a price term. The price term may include a formula arrangement or reference to a formula arrangement for calculating a fractional exposure of the entity to the commodity on each date in which an event affecting commodity transaction occurs. Each of these fractional exposures may be calculated for each commodity transaction and stored as separate entries in a data structure. The entries may then be updated, queried, and/or reorganized to generate an exposure position.

Abstract: A process for dyeing celluose-containing textile material with indigo comprises using an aqueous solution of leuco indigo prepared by catalytic hydrogenation and, after the leuco indigo has gone onto the textile material, converting it back into the pigment form in a conventional manner by air oxidation.

Abstract: Polycyclic vat dyes of the general formula I ##STR1## where X is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen or nitro, obtainable by reacting (9)-benzo-5-aminoanthraquinonyl(2,1-h)-8-azapyrenone-3(II) ##STR2## with a benzoyl chloride of the formula III ##STR3## in a dipolar aprotic solvent.

Abstract: Process for the continuous production of surface dyeings on cellulose fiber textile materials, characterized in that the textile materials are treated with an aqueous liquor containing at least 5 g/l of benzyl halide quaternized condensation products of precondensates of trialkanolamines and ureas, cyclic carbonates and/or epihalohydrins and/or benzyl chloride quaternized condensation products of piperazine and epichloronydrin, and 0.02 to 1 g/l of a phosphoric triester whose alcohol component has 6 to 18 carbon atoms, the textile materials thus treated are then dyed in another bath with reactive dyes in an aqueous medium and the dyes are fixed by treatment with an alkaline aqueous liquor and the dyeing finished in conventional manner. The individual cellulose fibers of the textile material are not completely penetrated by the dye but, on the contrary, exhibit ring dyeing.

Abstract: An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of(a) polyethylene oxide, a block copolymer of ethylene oxide and propylene oxide or an ether, ester or carbamate derivative thereof and(b) a polyoxyethylated amine.
