  • Patent number: 6458217
    Abstract: Systems useful for superadiabatic combustion generation of a reducing atmosphere for metal heat treatment include a superadiabatic reactor which supplies a reducing atmosphere to a metal heat treatment apparatus. In one aspect, the reactor includes a porous medium and a start-up heater in the flow path of the gas that is to be heated. In another aspect, the gas is passed through a porous medium in alternating, opposite directions by the control of valves which lead the gas to and from the medium. In yet another aspect, a gas inflow pipe leads into an insulated porous bed from which the gas flows in a counter flow manner around the inflow pipe.

  • Patent number: 6457327
    Abstract: The process removes from a diluted gas one or more fluorine compounds present at a first concentration in the diluted gas and concentrates the fluorine compounds. This is done by directly contacting the diluted gas with a cryogenic liquid having a temperature less than or equal to about −150° F., thereby producing a vapor lean in the fluorine compounds and liquid enriched with the fluorine compounds at a second concentration. The second concentration is greater than the first concentration.

  • Patent number: 6459717
    Abstract: An all gas phase iodine cw laser operating on the electronic I(2P3/2)−I*(2P1/2) transition of atomic iodine at 1.315 &mgr;m was described. The laser is based on the energy transfer reaction between metastable NCl(a1&Dgr;) and ground state I(2P3/2) atoms. This all gas phase laser has a number of advantages over previous aqueous-based chemical oxygen iodine lasers, including lighter weight, zero-gravity operation, and heat rejection in the exhaust.

  • Patent number: 6457782
    Abstract: An electropneumatic brake control valve unit capable of operating at the interface of the emergency brake portion or the service brake portion of a standard brake control valve as a retrofit unit or operating as a stand alone electropneumatic unit. The unit includes electric valves responsive to electrical signals and sensed brake pipe pressures to operate pneumatic valves to control the brake cylinder. The pneumatic valves are also operable independent of the electric control valves so as to allow braking with the electrical controls off or disabled. The unit can operate in combination with a complete brake control valve or with either or none of its emergency and service portions.

  • Patent number: 6455234
    Abstract: This invention provides water-based compositions, particularly coating, ink, fountain solution and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of an acetylenic diol ethylene oxide/propylene oxide adduct of the structure where r and t are 1 or 2, (n+m) is 1 to 30 and (p+q) is 1 to 30. Use of such adducts as surfactants in photoresist developer/electronics cleaning compositions is particularly advantageous. Also disclosed is a method for making random and block EO/PO adducts of acetylenic diols by reacting an acetylenic diol with EO and/or PO in the presence of a trialkylamine or Lewis acid.

  • Patent number: 6455728
    Abstract: A process for fluorinating &bgr;-dicarbonyls to form the corresponding &agr;-fluorinated-&bgr;-dicarbonyl compounds is provided. The process is represented by the following reaction scheme: where R1 is H, alkyl or alkoxy, R2 is H, alkyl or perfluoroalkyl, and R3 is H, Cl, Br, I or alkyl. Use of oxygen in the fluorine stream yields a product which is 90-96% pure and contains radical fluorination impurity levels which are 10-20% lower than when oxygen is not used.

  • Patent number: 6455134
    Abstract: Improved ink jet paper coatings which impart high optical density images and excellent water resistance by the incorporation of an amine functional, colloid-stabilized emulsion into the coating formulation. The improvement resides in the use of amine functional monomers, such as 2-(dimethylamino)ethyl methacrylate (DMAEMA), which are emulsion copolymerized with other ethylenically unsaturated monomers, such as vinyl acetate, in the presence of a large amount of a colloid stabilizing polymer having a plurality of pendent hydroxyl groups; preferably, poly(vinyl alcohol).

  • Patent number: 6455851
    Abstract: A spectroscopic IR and UV-vis absorption remote exhaust emission monitoring system and sensing instrument for non-invasive, multicomponent analysis of the exhaust plume emitted by in-use vehicles. The concentration of CO, CO2, HC, NO, N2O, C2H2, NH3, SO2, Aromatic hydrocarbons, aldehydes, HONO, NO2, and dust, among others and in any combination there-of, in such a mixture can be determined in real-time, or via post-processing of stored spectral data. The sensor employs an IR and a UV-vis sources, and the physically offset, collimated beams traverse the probed air column, typically a roadway, a plurality of times, before returning to the instrument. Although the IR and UV-vis beams converge at the optics opposite the instrument, they are not coaxial and, thus, do not require an optical device (i.e., dichroic beam splitter) to separate them. The separate IR and UV-vis beams are focused on the slits of rapid spectrometers, where they are analyzed to yield wavelength-resolved spectra (i.e.

  • Patent number: 6453790
    Abstract: A system for communicating hardened, buried target arrival-related data from an airborne warhead device to a remote mission analysis location is disclosed. The communicated information especially relates to impact deceleration events encountered by a hardened target penetration warhead, events arising from the warhead impacting with the earth and then with one or more layers of hardening material such as concrete disposed in or adjacent a subterranean target. Verification of warhead detonation may also be included in the communicated data. The system includes ultra high radio frequency communication from the subterranean warhead to a repeater apparatus disposed at or above the point of warhead earth impact followed by conventional signal relaying of the collected warhead experience data from the repeater to a remote mission analysis facility.

  • Patent number: 6454981
    Abstract: A method for accelerating the release of a flammable blowing agent from an expanded foam is disclosed. According to the method, an expanded foam structure is perforated to form a first series of channels extending partially through its thickness from a first surface and a second series of channels extending partially through its thickness from a second surface opposite the first surface. The channels provide paths enabling the blowing agent to escape more rapidly from the interior of the expanded foam structure.

  • Patent number: 6454562
    Abstract: A process controls oxy-boost firing and air-fuel burner firing in furnaces, including large glass furnaces such as float furnaces. The large side-fired regenerative float furnaces use oxy-boost firing for a variety of reasons, including production increase, improved glass quality, lowering of superstructure temperatures, and reduction of emissions. An adaptive controller receives input data from process parameter sensors throughout the furnace, and adjusts its control logic for controlling both the oxy-boost burners and the air-fuel port burners.
