摘要： The process for removal of contaminants from coolants involves using an inorganic hydrophilic membrane, such as a ceramic membrane with varying pore sizes, to remove lead particulates, including soluble lead that is converted to insoluble lead precipitates, and oil from machining coolant solutions. The treated coolant with the lead substantially removed is then recycled back to the coolant tank that is used for machining lead alloy parts.

摘要： This invention provides a method or process for separating an organic chlorinated contaminant such as polychlorobiphenyl from an inert porous material which comprises admixing the material with an effective amount of a volatilizable organic liquid in which the contaminant is soluble, heating the admixture under vacuum to a temperature above the boiling point of the organic liquid but below the decomposition temperature of the organic liquid and the contaminant, while maintaining a flow of an inert sweep gas through the porous material, and collecting the vapors for further treatment which includes recovery of the organic liquid for reuse in the decontamination of soil and other porous materials. Recovery of the organic liquid is achieved by passing the vapors from the separation step through a bed of activated carbon at a temperature above the vaporization temperature of the organic liquid. The carbon selectively adsorbs and holds the contaminant while the organic liquid in vapor form passes through and is recovered by condensation and recirculated to enhance decontamination of additional material.

摘要： Fluoride is recovered from an aqueous ammonium fluoride and ammonium hydroxide solution by electrolyzing the solution in an electrochemical cell having an ion-exchange membrane between a catholyte chamber and an anolyte chamber whereby hydrofluoric acid is formed and the concentration of ammonium hydroxide is enriched. Part of the hydrofluoric acid can be combined with the ammonium fluoride remaining after the ammonium hydroxide had been stripped from the treated solution to produce ammonium acid fluoride.

摘要： An expanded fiber composite structure and process for making an expanded fiber composite structure are provided. The expanded fiber composite structure is made up of a fiber mat held in partial compression by a monolithic plastic coating on the fibers, the structure having a plurality of interstitial voids which may optionally be filled with a polymeric interstitial material. The process includes impregnating a fiber mat with a plastic material, compressing the mat to impregnate the mat with the plastic, fully wetting each fiber and creating a substantially void-free fiber/plastic matrix, and reducing the compressive forces on the mat, allowing the fibers to rebound and expand the mat to a predetermined desired thickness, in the process creating the interstitial voids. The structure is then cooled such that the plastic material stiffens and itself retains the structure at the desired thickness. The process optionally employs the addition of a molten polymeric material to the expanded or lofted mat, the material filling the interstitial voids in the structure. The composite structure may optionally be produced from a fully compressed plastic-impregnated fiber mat by heating to a temperature sufficient to loft the material and controlling the amount of lofting after the heat is applied.

摘要： A method for the removal of molybdenum from solutions containing molybdenum and other mineral values such as tungsten is accomplished by mixing the leachate solution with hydrogen peroxide to form a feed solution; the feed solution is contacted with a porous membrane, the opposite side of which is continuously contacted with an organic solution containing tributylphosphate. Additionally, for recovery of molybdenum, the tributylphosphate solution is additionally contacted with a second membrane the opposite side of which is contacted with a stripping solution such as a solution of sodium hydroxide or sodium carbonate. In a continuous ion exchange embodiment, the organic solution containing tributylphosphate is recirculated to contact the second side of the first membrane, preferably after passage through an aqueous separator.

摘要： A process for forming a thermoplastic resin coating on glass fibers comprises heating a thermoplastic resin powder until molten and applying it to the glass fibers. The coated fibers can then be heated and drawn into a desired shape which also removes resin. Then the coated fibers are cooled to make a preform. The coated fiber preform can then be molded. Several resin layers with glass fibers of varying lengths can be deposited to make a graded preform. Apparatus for forming a thermoplastic resin on glass fibers sprays hot thermoplastic powder on the glass fibers. The coated fibers can then be heated such as by IR lamps and then drawn through a die which has a spigot to remove excess plastic. Alternately, a plurality of plastic and glass fiber layers can be deposited on a veil.

摘要： A mold structure including layers with different physical properties is used to provide hot surface during molding. The use of a thin layer of low thermal conductivity covered by a smooth skin layer prevents quick cooling of the surface of the pre-heated plastic to be molded. The plastic surface remains molten and flows to fill the mold during press closing, resulting in smooth surfaces even when fiber reinforced plastics are used.
