  • Patent number: 5419790
    Abstract: A non-toxic corrosion resistant conversion coating for aluminum is formed by a process which includes subjecting the aluminum to an acidic aqueous solution containing potassium permanganate and cerous chloride, alone or in combination with strontium chloride. The corrosion resistance is improved by a subsequent treatment in an alkaline solution containing molybdate, nitrite and metasilicate ions. The corrosion resistant is further improved by treating the coated surface with an acholic solution containing glycidoxy(epoxy)polyfunctionalmethoxysilane, alone or in combination with phenyltrimethoxysilane. The coating thus produced is a mixture of oxides and hydroxides of cerium strontium and aluminum. These oxides and hydroxides may also be intermixed with molybdate silicate and nitrite ions. In the most corrosion resistant form the mixture further includes a silane overcoat.

  • Patent number: 5235191
    Abstract: An x-ray imaging system includes an x-ray source for providing x-ray photons which are directed towards a subject and impinge on a scintillating screen. The scintillating screen converts the x-ray photons into a visible light image. The screen is formed of discrete, elongate fiber optic elements arranged side-by-side, having a mirrored surface at one end thereof. The elements are formed of a mixture of glass and rate earth elements which convert the x-ray photons into visible light by first phosphoring and then lasing. The system includes a camera system for capturing the visible light image for remote viewing. A method of constructing the scintillating screen of the invention is disclosed.

  • Patent number: 4617105
    Abstract: An improved process for thermal solvent refining or hydroliquefaction of non-anthracitic coal at elevated temperatures under hydrogen pressure in a hydrogen donor solvent comprises pretreating the coal with a binary mixture of an aromatic hydrocarbon and an aliphatic alcohol at a temperature below 300.degree. C. before the hydroliquefaction step. This treatment generally increases both conversion of coal and yields of oil.

  • Patent number: 4609455
    Abstract: A coal liquefaction system is disclosed with a novel preasphaltene recycle from a supercritical extraction unit to the slurry mix tank wherein the recycle stream contains at least 90% preasphaltenes (benzene insoluble, pyridine soluble organics) with other residual materials such as unconverted coal and ash. This subject process results in the production of asphaltene materials which can be subjected to hydrotreating to acquire a substitute for No. 6 fuel oil. The preasphaltene-predominant recycle reduces the hydrogen consumption for a process where asphaltene material is being sought.

  • Patent number: 4465587
    Abstract: A process is set forth for the solvent extraction and hydroliquefaction of heavy hydrocarbon oils and residua having an API gravity at 60.degree. F. of less than 20.degree. in the presence of a hydrogen atmosphere and a hydrogen donor solvent at elevated temperature and pressure. Alternately, the hydrocarbon feed can be subjected to a vacuum distillation before solvent extraction or the liquefaction can be catalyzed in-situ. The process results in improved oil production and greater denitrogenation desulfurization and demetallization.

  • Patent number: 4327152
    Abstract: A protective coating to retard crack growth in aluminum and aluminum alloys has particular utility when applied to the surfaces of structural parts of aircraft providing a crack growth inhibitor to a crack surface when and as it develops in such parts. This inhibitor is a compound having a vapor pressure high enough to volatilize the inhibitor and emit molecules which will react with the surface of the metal to form a protective film. It is blended within a selected primer and is thereby available for interaction with the surface and tip of any crack which may initiate beneath the primer. A topcoat of low-permeability polyurethane covers the inhibitor-reinforced primer to prevent escape of the inhibitor from the primer.
