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 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： Apparatus and method for regenerating saturated adsorbents using microwave energy. A saturated adsorbent, such as activated carbon, is fed onto a continuously moving conveyor belt. The conveyor belt transports the carbon to a microwave cavity where the carbon is exposed to microwave energy. The cavity is defined by a containment enclosure which is sealed to prevent radiation leakage. The carbon is heated to a sufficient temperature to cause the contaminants to desorb. The system also includes vents for removing the desorbed contaminants and a holder for receiving the treated carbon discharged from the belt. The microwave cavity may be divided into a number of heating compartments so that the carbon on the belt is heated to different temperatures in each compartment. Each compartment is separately vented, thereby allowing selective recovery of the different contaminants in the carbon.

摘要： A thermoplastic sheet is placed between a pair of mold members each having a thermal insulator and a mating metal mold insert. RF energy is applied to the inserts to dielectrically heat and melt the thermoplastic sheet. The heated sheet is then deformed in a low pressure press with the insulators. The insulators are then replaced with cool thermally conductive structures to shorten the cooling cycle time. The thermally conductive structures cool the sheet by pressing the sheet in a high pressure press.

摘要： Microwave heating is used to desorb successive batches of contaminated adsorbent. The apparatus includes first and second stations and an adsorbent carrier tray displaceable between the two stations. Adsorbent is loaded and unloaded from the tray in the first station and heated with microwave energy in the second station. The tray is loaded by passage under a feed hopper, thereby providing an even bed of adsorbent in the tray. Unloading is performed by rotating the tray to an inverted position so that the adsorbent falls into a bin below. The second station includes an oven chamber which is swept with a purge gas to remove gaseous sorbates desorbed from the adsorbent. The tray can include a gas-permeable adsorbent support structure to facilitate passing purge gas and gasification reactants through the adsorbent bed.

摘要： Contaminated material is decontaminated using a process in which fractions of the contaminated material are sequentially exposed to a polymeric sorbent to enhance removal of contaminants. The contaminated material is first converted into a slurry which may be divided into a sand slurry and a slimes slurry. A quantity of large polymeric sorbent particles are first contacted with the slimes slurry and then separated and contacted with the sand slurry. The sorbent particles are then separated from the sand slurry which is exposed to the action of a flotation cell. The concentrate removed from the flotation cell is then exposed to the polymeric sorbent particles. At least a portion of the sorbent particles are then thermally regenerated and recycled. One preferred material for the polymeric sorbent is nitrile-butadiene rubber.
