Abstract: A process for the production of liquid epoxy resins, including: contacting a polyhydric phenol and an epihalohydrin in the presence of an ionic catalyst to form a halohydrin intermediate reaction product; concurrently: reacting a portion of the halohydrin intermediate reaction product with an alkali hydroxide to form a solid salt suspended in a liquid mixture including a dehydrohalogenated product and unreacted halohydrin intermediate, wherein the alkali hydroxide is used at less than a stoichiometric amount; and removing water and epihalohydrin as a vapor from the reacting mixture; separating the solid salt from the liquid mixture; reacting at least a portion of the unreacted halohydrin intermediate with an alkali hydroxide in the presence of water to form an organic mixture including an epoxy resin and unreacted epihalohydrin and an aqueous solution including a salt; separating the aqueous mixture from the organic mixture; and separating the unreacted epihalohydrin from the liquid epoxy resin.

Abstract: In the method, an adapter is substituted for the filter-enclosing cap of a conventional in-line strainer device to permit introduction into a plumbing system of a flushing solution withdrawn from an independent supply. The method is typically used for introducing antifreeze into the system for winterization purposes.

Abstract: Diphones are prepared for text-to-speech converting by selectively pronouncing a set of selected diphones and processing each such diphone for persistent storage. Finally, each processed diphone is stored in an individually addressable manner. In particular, amongst such set as spoken by a single person, on a basis of homophony each diphone is assigned to one or more diverse languages. Sharing of selective diphones amongst more than one language diminishes required storage. The storage may entail language-specific processing qualifiers.

Abstract: Wearing apparel for protecting the wearer against radioactive contamination is manufactured from single use disposable laminated material which comprises a first continuous layer of non-macerating hypoallergenic cellulosic material for contact with the wearer's skin and a second continuous layer of cellulosic material exposed to external contamination. The first and second layers are bonded together with a third contiguous layer interposed between them. The third layer is of a microporous adsorbent material allowing passage of body vapors from the wearer to the ambient region while restricting passage of liquid in the opposite direction. The laminated material exhibits a tensile yield strength of at least approximately 2,000 psi, a shear yield strength of at least approximately 1,000 psi, and an overall coefficient of heat transfer of at least approximately 2.75 BTU/hr.ft.sup.2 -.degree.F. The microporous adsorbent material may be activated charcoal or hydrated alumina silicate.
