Abstract: A rotary, continuous pyrolytic conversion system converts solid hydrocarbons into gases, liquid hydrocarbons and char by pyrolyzing feed stocks including: plastic waste, tires and plastic from automobile shredding operations; containers and trays of styrofoam and other plastic materials such as used in "fast food" restaurants; rubber; leather; tires; garbage; sewage sludge; coal; oil shale; broken asphalt and the like. These materials are preferably shredded and kinds thereof having different melting points are mixed to facilitate movement of the feed stock through the converter without clogging. Preferably, the materials are baled and injected into the converter where they are severed as they are injected. The materials are fed by gravity from the input end of a converter drum to the discharge end thereof; the input end being elevated above the discharge end. The converter drum is contained within an outer drum which is in substantially air-tight relationship with the injector for the bales and with a discharge chute for the solid products of pyrolysis. A casing around the outer stationary drum defines an oven chamber which is heated by combustion products, from a burner providing a heat source, which circulate in heat exchange relationship with a matrix of fins extending into the oven from the stationary outer drum. A rod extends into the injection end of the converter drum for supporting scrapers against the inner periphery of the converter drum. A crusher bar is carried in the drum at the discharge end thereof and crushes the solid products which consists of char (mostly carbon black), metals and other non-organic materials. A chute containing water receives the pulverized discharge product and balances the pressure in the converter to maintain an air-tight seal therein. A second pyrolysis reactor may receive the solid pyrolysis products and be operative at higher temperature than the first converter to destroy chlorinated hydrocarbons. To assist in such destruction, lime may be injected into the first converter. A plurality of converters may be operated in parallel and utilize common equipment for cleaning the product gases released upon pyrolysis and to supply them to the burners of each of the reactors. Flue gases from the oven chambers of one of the plurality of converters may be supplied to the burner of the next converter for preheating gases for combustion therein.

Abstract: A method for encapsulating biologically-labile materials such as proteins, liposomes, bacteria and eucaryotic cells within a synthetic polymeric capsule, and the product thereof, are disclosed. The method is based on the use of a water-soluble polymer with charged side chains that are crosslinked with multivalent ions of the opposite charge to form a gel encapsulating biological material, that is optionally further stabilized by interactions with multivalent polyions of the same charge as those used to form the gel. In the preferred embodiment, hydrolytically stable polyphosphazenes are formed of monomers having carboxylic acid side groups that are crosslinked by divalent or trivalent cations such as Ca2+ or Al3+, then stabilized with a polycation such as poly-L-lysine. A variety of different compositions can be formed from the crosslinked polymer. In a preferred embodiment, microcapsules are made by spraying an aqueous solution of polyphosphazene and material to be encapsulated into a calcium chloride solution.

Abstract: A fault-tolerant storage device array using a copyback cache storage unit for temporary storage. When a Write occurs to the RAID system, the data is immediately written to the first available location in the copyback cache storage unit. Upon completion of the Write to the copyback cache storage unit, the host CPU is immediately informed that the Write was successful. Thereafter, further storage unit accesses by the CPU can continue without waiting for an error-correction block update for the data just written. In a first embodiment of the invention, during idle time for relevant storage units of the storage system, an error-correction block is computed for each "pending" data block on the copyback cache storage unit, and the data block and corresponding error-correction block are copied to their proper location in the RAID system. The copyback cache storage unit in effect stores "peak load" Write data and then completes the actual Write operations to the RAID system during relatively quiescent periods of I/O accesses by the CPU. In a second embodiment of the invention, after Write data is logged to the copyback cache storage unit, normal Read-Modify-Write operation by the RAID system controller continues in overlapped fashion with other CPU I/O accesses using Write data in the controller's buffer memory. Performance is enhanced because the CPU can continue processing as soon as the simple Write operation to the copyback cache storage unit completes, thus eliminating the delay caused by a normal Read-Modify-Write RAID system. In this embodiment, the copyback cache storage unit acts more as a running "log" of Write data.

Abstract: The invention relates to an electrical logging method and apparatus using electrodes. The apparatus comprises an annular current electrode (Ao) mounted on a body and guard electrodes (A2, A'2) disposed on the body above and below the annular current electrode. A first measurement current (Io) is emitted by the central current electrode (Ao) and focusing currents are emitted by the guard electrodes (A2, A'2). A first output signal representative of the deep resistivity of the formations is generated in response to the first measurement current (Io). One of the guard electrodes (A2) comprises two longitudinally spaced-apart portions, and an array of azimuthal current electrodes (Aazi) that are circumferentially spaced-apart from one another is disposed between these two portions. Second measurement currents (Aazi) emitted by the azimuthal current electrodes (Aazi) are focused longitudinally by the currents emitted by the said two portions of the guard electrode (A2). Second output signals are generated in response to the second measurement current (Iazi), which output signals are representative of the resistivity of the formations in a plurality of directions around the borehole. A high resolution resistivity signal is calculated as a function of the mean of the second measurement currents (Iazi). <IMAGE>

Date Jan. 5, 1995This invention relates to a process for preparing ceramic-like materials with specific properties by binding an inorganic filler in the form of a dry composition with a grain size of up to 25  mu m containing in the volume ratio 1:0.-1.52 a waste phosphogypsum and magnetite or glass-forming oxides, with an unsaturated polyester resin in an amount of 46-220 volume parts per 100 volume parts of the filler. The use of magnetite makes it poisible to prepare materials with magnetic properties, while glass-foming oxides enable preparing materials effective to absorb an X-radiation of 45-55 keV and a hard radiation of 0.6-125 MeV. When an expanding agent is added to the raw composition according to this invention, an expanded material is obtained, having completely closed pores, particularly useful in the building industry. The resultant ceramic-like materials are characterized by good adhesion to metals, plastics, glass, wood, concrete and can be easily joined with them both at the stage of polymerization and after its termination by using a prepolymerized resin as a binder.
