Abstract:
A method and apparatus is disclosed for interacting with a computer reservation system. A client computer (12) generates commands in response to user input. A server computer (14) receives the commands and generates requests to a computer reservation system through application program interfaces responsive to the commands. After receiving sets of reservation data from the computer reservation system in response to the requests, the received data is normalized and selected portions are returned to the client computer (12).
Abstract:
A process for the separation of naphthalenesulfonate-based carbonyl condensates from water is provided. The process comprises contacting a mixture comprised of water and a naphthalenesulfonate-based carbonyl condensate (preferably a material selected from the group consisting of formaldehyde condensates of naphthalenesulfonic acids, formaldehyde condensates of lower-alkyl substituted naphthalenesulfonic acids, and mixtures of two or more of such materials) with a liquid organic phase comprised of a cationic lipophilic amine to form an aqueous phase depleted with respect to said mixture of naphthalenesulfonate-based carbonyl condensate and a liquid organic phase enriched in naphthalenesulfonate-based carbonyl condensate. The process further comprises separating said aqueous phase depleted with respect to said minute of naphthalenesulfonate-based carbonyl condensate and said liquid organic phase enriched with respect to naphthalenesulfonate-based carbonyl condensate. The liquid organic phase can then be stripped with an alkaline stripping solution to regenerate the cationic lipophilic amine.

Abstract:
Stable aqueous dispersions of finely divided piperazine-containing polyamide resin particles and methods for the manufacture thereof are provided. Dispersions according to this invention find use in hot melt adhesives, coatings, inks, and the like.
Abstract:
A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acide number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A surfactant which will promote the emulsification of the polyamide resin and water is included in the mixture. The resulting mixture is then subjected to sufficient comminuting forces to form an emulsion in which droplets of the polyamide resin have a volume average size distribution of about 20 microns or less in diameter and preferably 5 microns or less. The resulting emulsion is then cooled to a temperature below the melting point of the polyamide resin causing the emulsified droplets of the polyamide resin to solidify as finely divided particles which are dispersed uniformly through the aqueous phase. The resulting stable aqueous dispersions of the polymerized fatty acid polyamide resin which are obtained are especially useful for hot melted adhesive applications, and when utilized in coating, inks, and the like.
Abstract:
Aqueous dispersions of acrylate-modified polyamide resin having unreacted acrylate functionality are provided. These acrylate-modified polyamide dispersions cure upon exposure to either ultraviolet radiation or thermal energy to form cross-linked films useful, for example, as adhesive coatings. In a preferred embodiment, acrylate-modified dispersions are formed by the addition of a polyol ester having a multiplicity of acrylate ester groups to a polyamide resin having a multiplicity of free amino groups under conditions effective to form the Michael addition product thereof.
Abstract:
A high voltage circuit interrupter, having telescopic tubular insulating and conducting casings, contains an expulsion end sealing construction which hermetically seals and controls the expulsion rate of the interrupter. The expulsion end includes a sleeve, a thin, rupturable diaphragm affixed against the sleeve by cyanoacrylate cement, and an end cap. Epoxy cement is applied into the cap so that the space between the diaphragm and the end cap are filled forming a sealant layer therebetween. A main ferrule secures the strain element, and an auxiliary ferrule secures both the main ferrule and the end cap onto the end of the tubular insulating casing.
Abstract:
In a coal cleaning process in which oil is used as a cleaning medium, oil remaining in the solid refuse of the cleaning process is recovered for reuse by multi-stage treatment using a volatile solvent such as liquefied petroleum gas. The oil and solvent are separated by evaporation and the gaseous solvent is liquefied for reuse. A similar process is usable for removing oil from coal to produce a dry coal.
Abstract:
A high visibility safety eyewear assembly includes a frame and a pair of temples that are attached to and extend rearwardly of the frame. A lens is attached to and extends downwardly from the frame. The lens includes lateral sides extending to a forward section of each of the temples. The lens are comprised of an impact resistant material. A reflective material is attached to and extends along a front side of the frame and further extends beyond the frame and onto each of the temples. A light emitter is mounted on a first temple of the pair of temples. The light emitter is directed forward of the frame. An actuator is engaged with the light emitter to turn the light emitter on or off.
Abstract:
Lignocellulosic composites are made by pressing a mixture of a particulate lignocellulosic material with polymeric MDI, in the presence of a fatty amine ethoxylate anti-masking agent.
