    Abstract: The instant invention relates to concentrated aqueous solutions of hexasulphonated stilbene optical brighteners which are storage-stable in the absence of solubilizing agents like urea. By removal of salts resulting from the preparation of the optical brightener one can obtain a concentration of up to 0.350 mol/kg without losing storage stability. The reduced water content enables coating compositions which require less drying energy and which show less water and binder migration into the paper.

    Abstract: A process for upgrading a light olefin feed by converting the 1-olefins to higher molecular weight oligomers and the iso-oleins to fuel ethers or alcohols. The process provides substantial improvements in the production of lower alkyl tertiary alkyl ethers or tertiary alkyl alcohol, such as methyl tertiary butyl ether (MTBE), methyl tertiary amyl ether (TAME) or tertiary butyl alcohol. The 1-olefin component of the hydrocarbon feedstream is separated by selective oligomerization in contact with a reduced chromium oxide catalyst to form an olefin oligomer of higher molecular weight, such as gasoline, distillate and lube range hydrocarbons. The iso-olefins are separated by etherification with a lower alcohol such as methanol or by hydration to form an alcohol such as tertiary butanol. The oligomerization process can be integrated either upstream or downstream of the etherification step.

    Abstract: A novel composition is disclosed that is particularly useful as a lubricant viscosity index improver. The composition comprises branched branched C.sub.30 -C.sub.10000 hydrocarbons that have a branch ratio of less than 0.19 and viscosity at 100.degree. C. between 725 CS and 15,000 cS. The novel compositions comprise the product of the oligomerization of C.sub.6 to C.sub.20 alpha-olefin feedstock, or mixtures thereof, under oligomerization conditions at a temperature between -20.degree. C. and +90.degree. C. in contact with a reduced valence state Group VIB metal catalyst on porous support. The compositions have viscosities at 100.degree. C. between 725 cS and 15,000 cS. Using the foregoing compositions in admixture with mineral oil and synthetic lubricants provides novel lubricant blends that show an elevated viscosity index. The mixtures also show an increased stability to shear stress at high temperature with all blends notable by exhibiting Newtonian flow.

    Abstract: A system and method for determining approval of a multi-currency transaction between a customer and a merchant over a network. The system includes a customer computer which is connected to a communication network, a merchant computer which is connected to the communication network, and a server connected to both the customer computer via the communication network and to the merchant computer via the communication network. The customer computer includes a first set of data which contains an amount the customer is willing to pay the merchant for a product in a first currency. The merchant computer includes a second set of data which contains a product price at which the merchant agrees to sell the product in a second currency. The server receives the first set of data and the second set of data. The server then converts the amount in the first currency into a converted amount in the second currency. The server approves the transaction if the converted amount in the second currency is within a risk range of the product price in the second currency in accordance with current exchange rates. Once the transaction is approved, the approving entity may settle the transaction at its discretion thereby bearing the risk associated with currency exchange. The parties, however, incur no risk. The customer will pay the amount in the first currency and the merchant will receive the price in the second currency. These are values known and agreed to by the parties at the time of the transaction.
