摘要:
Methods, systems, and products are disclosed in which generating evidence of web services transactions are provided generally by receiving in an ultimate recipient web service from an initial sender a request, the request containing a proof of message origin (‘PMO’). The PMO contains an element addressed to the ultimate recipient web service and the element bears a first signature, the first signature having a value. Embodiments also include authenticating the identity of the initial sender; creating a proof of message receipt (‘PMR’) including signing the value of the first signature; sending the PMR to the initial sender, receiving, by the initial sender, the PMR; and saving, by the initial sender, the PMR.
摘要:
This invention relates to the preparation of poly(dithio thiadiazole) by combining an oxidizing agent, a dithio thiadiazole, and an aprotic polar solvent thereby producing a polymer precipitant which may then be washed to remove residual contaminants.
摘要:
Providing water management services includes generating a water accounting model. The model is generated by selecting data, via a user interface implemented by a computer processor, from options including water quality, water quantity, and water usage. The model is further generated by defining, via the user interface, parameters of the data for a geographic region, and defining, via the user interface, actions to be taken. Providing the water management services further includes mapping communications addresses of data sources of data selected via the user interface to the water accounting model, receiving input values for the data via the communications addresses from the data sources, executing the water accounting model, and identifying and implementing an action responsive to results of executing the mode.
摘要:
A prepolymer for use in preparing photocurable compositions is prepared by reacting an aliphatic diisocyanate having terminal isocyano groups and at least one alkyl side chain with a hydroxy-, mercapto- or amino-containing olefinically unsaturated compound. This prepolymer is compounded with a photosensitizer and, optionally, a polymercaptan to prepare photocurable compositions.
摘要:
Dialkyltin bis(3-sulfolanylmercaptides) have been found to be excellent stabilizers against heat degradation of halogen-containing polymer, e.g., polyvinyl chloride. New tin-containing compounds are disclosed along with a process for making the same.

摘要:
The heavy reaction product obtained upon separation, as by distillation, of light reaction products of branched aliphatic dinitriles is useful as rust inhibitor in lubricating oils and greases.

A mixture of polyamines obtained as a heavy residue from the distillation of a reaction product from the hydrogenation of branched aliphatic dinitriles is useful as curing agent for epoxy resins showing lowered water absorption and significantly higher lap shear strength.
摘要:
Lubricating compositions incorporating therein at least one mercapto-substituted boron-containing compound selected from 2-hydroxy-4-(mercaptohydrocarbyl)-1,3,2-dioxaborolanes and alkylammonium bis[(mercaptohydrocarbyl)ethylenedioxy]borates. Novel 2-hydroxy-4-(mercaptohydrocarbyl)-1,3,2-dioxaborolanes and novel alkylammonium bis[(mercaptohydrocarbyl)ethylenedioxy]borates and methods for preparing these compositions of matter are provided. Alkylammonium bis[(mercaptohydrocarbyl)ethylenedioxy]borates are prepared from an intermediate chemical compound that is a novel hydrogen bis[(mercaptohydrocarbyl)ethylenedioxy]borate for which a method of preparation is also provided.
