Title: Apparatus and method for waste disposal
Inventor: ABRISHAMIAN RAMIN
IPC: F23G7/00
Filed: 1988-11-10
Granted: 1991-07-30
Abstract: ABSTRACT OF THE INVENTION   Apparatus for and method of thermally decomposing wastes laden typically with organic solvents, other organic liquids and soluble organic materials, by first extracting such wastes in a pressure vessel using a fluid extractant in which the organics are soluble, thereby producing a fluid extract of the organics in the extractant fluid and a non-extracted residue of reduced BTU/lb value.  The extractant fluid, typically propane, is preferably a gas at ordinary conditions of temperature and pressure but in the pressure vessel means is held to conditions of temperature and pressure sufficient to render the extractant fluid a solvent for the organics.  Means are provided for separating the residue from the organics extracted from the waste material, and the residue is burned typically in a solids incinerator The fluid extract is separated into an extracted organics fraction and an extractant fraction, the latter being recycled for use in the pressure vessel. The extracted organics fraction is employed as auxiliary fuel for either the solids incinerator or ` for an afterburner to which the flue gases from the incinerator are fed for further, high temperature incineration.

Abstract: ABSTRACT OF THE DISCLOSURE     A diamond laser formed of synthetic diamond and providing high output power and variable wavelength in the near infrared region.  The maximum value of the optical density of H2 centers in the direction of pumping light is in the range of 0.01 - 4.  Laser action is effected in the range of 1000 - 1400 nm by means of external pumping light at 650 - 950 nm.  Such diamond laser is produced by preparing a synthetic Ib type diamond whose nitrogen concentration is 1 x 1017 - 8.5 1019 atoms/cm3, subjecting this synthetic diamond to electron irradiation to a dose of not less than 5 x 1017 electrons/cm2, and heat-treating the synthetic diamond in a vacuum of not more than 1 Torr or in an inert gas atmosphere and at 1400 - 1850°C.  Let Ith the threshold value of pumping light intensity necessary for laser action.  Then, to make the pumping light intensity I greater than Ith throughout the laser crystal, it is important that the maximum value of optical density of H2 centers be between 0.01 and 4.

Title: Braided yarns for oms loops
Inventor: DAVENPORT FRANCIS L
IPC: D02G3/44
Filed: 1989-04-12
Granted: 1993-02-02
Abstract: ABSTRACT OF THE DISCLOSURE    This disclosure shows the use of a composite yarn for the MD strands of an OMS press fabric, designed to be closed by means of a pin seam.  The composite yarn includes braided strands of monofilament.   The OMS loops formed by the MD strands  of  the  fabric  are,  as  a  consequence,  likewise braided.   As a result, good loop formation and integrity is maintained  and  the  commonly  encountered  twisting  of  the loops about axes parallel to the machine direction, referred to as the secondary helix effect, does not arise.  Braiding provides the additional advantages of MD extendibility and improved fatigue resistance compared to those observed with a single monofilament.

Abstract: An improved process for separating a hydrocarbon bearing feed gas containing methane and lighter, C2 (ethylene & ethane) and heavier components into a fraction containing predominantly methane and lighter components and a fraction containing predominantly C2 and heavier hydrocarbon components including the steps of cooling and partially condensing and delivering the feed stream to a separator to provide a first residue vapor and a C2 containing liquid, directing a portion of the C2 containing liquid into a heavy ends fractionation column wherein the liquid is separated into a second hydrocarbon bearing vapor residue and a C2 containing product, conducting a portion of the first residue vapors with at least part of the partially condensed second residue into a light ends fractionating column to thereby obtain third residue vapors and liquids, supplying the liquids recovered from the lights ends fractionating column to the heavy ends fractionation column as the liquid feed thereto and directing part of the C2 containing liquid from the first step into intimate contact with the second residue, which liquid provides additional liquefied methane which acts with the partially condensed second residue as a direct contact refrigerant to thereby condense C2 and heavier components while the methane itself is evaporated in the light ends fractionation column.

Abstract: (1) ABSTRACT                 INJECTION MOLDING                      MACHINE        An injection molding machine comprises sorting means, which are disposed under the injection mold and comprises a swivel plate, which is pivotally movable by means of a motor-driven swivel drive to two mutually oppositely inclined positions for a delivery of usable moldings and for a delivery of rejects and sprues, respectively. In the position for a delivery of usable moldings, the delivery end of the swivel plate is disposed over means for receiving the usable moldings (belt conveyor). In the position for a delivery of rejects and sprues, the delivery end of the swivel plate is disposed over a disintegrator. The disintegra-tor comprised a cutting mechanism, which constitutes a unit, which is removable out of the machine pedestel, and a motor-transmission block, which is disposed out-side the vertical projection of the cutting mechanism. The sorting means are incorporated in a sorting unit, which is removable out of the machine pedestal. Owing to that design, the financial resources and the different manu-facturing processes of potential customers can better be taken into account. The injection molding machine can be delivered in different degrees of automation and can be converted to a higher degree of automation without a (2) large expenditure of work. The cutting mechanism has a simple design and can be removed out of the machine pedestal with a small expenditure of work when the cutting mechanism is to be replaced, repaired or cleaned.

Title: Coreactive oligomer blends
Inventor: SHEPPARD CLYDE H
IPC: C08G81/00
Filed: 1989-09-18
Granted: 1997-12-09
Abstract: The physical properties of high performance composites can be tailored by using coreactive oligomer blends to make the composites.  The blends include a first oligomer having an unsaturated hydrocarbon end cap and a second oligomer having an amine, hydrosyl, sulfhydryl, or   functionality.  Upon curing, the oligomers homopolymerize (i.e. addition polymerize) and mutually interlink (i.e. copolymerize) to form composites possessing intermediate properties to those exhibited by the pure oligomers.  The coreactive oligomer blends may also include noncrosslinking polymers and other coreactants, as desired.  Stiffness or toughness can be increased in thermally stable composites without significant loss of other properties through these coreactive oligomer blends that cure to block copolymers.
