    摘要： A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for recovery and/or subsequent hydrocarbon synthesis. Sources of a light hydrocarbon gas, such as methane, and oxygen or an oxygen-containing gas are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired relative proportions, at a plurality of mixing nozzles which are open to the catalytic partial oxidation reaction zone and are uniformly-spaced over the face of the injector means, to form a reactant gaseous premix having a pressure drop equal to at least about 3% of the lowest upstream pressure of either of said gases. The gaseous premix is injected in a time period which is less than its autoignition time, preferably less than 9 milliseconds, at a velocity between about 25 to 1000 feet/second, into a catalytic partial oxidation zone so that the gaseous premix reacts in the presence of the fixed catalyst to reduce the amounts of CO2, H2O and heat produced by the partial oxidation reaction, to form a useful syngas which is cooled and recovered.

    摘要： A method is described for producing an electronically passivated stable surface on silicon wafers. The passivation technique consists of first fluorinating the surface of a crystalline silicon wafer under inert atmospheric conditions. Such a treatment may consist of either a vapor phase or liquid phase application of HF at room temperature. The surface fluorinated wafer is then maintained in an inert atmosphere and a thin coating of an organic solid is applied to the wafer which does not disturb the underlying passivated silicon surface. The wafer may then be further processed into a variety of different devices.

    摘要： Extremely small, three-dimensional articles, such as fusion targets having glass shells (20 to 500 microns in diameter) are coated with alternate layers of colloidal materials. This is accomplished by depositing particles of opposite charge from colloidal suspensions (sols). Articles to be coated are suspended within a drop held in the open end of a closed capillary tube, and colloidal particles are deposited by dipping the capillary into the sols. Alternate monolayers of the particles adhere to the surface of the article. Multilayer coatings are built up by repeated alternate deposition of the monolayers from the sols. Between each deposition, the layers are rinsed with water and the water removed by dipping the capillary tube into a bath of water and then into a bath containing a water displacing agent such as ethanol or dimethyl sulfoxide.

    摘要： Identical half-section shells of microscopic size, such as hemispherical shells from which spherical laser fusion targets can be made are capable of mass production by micro fabrication molding techniques. A body (preferably a hollow glass microsphere which is called a glass microballoon) provides a pattern for the hemispherical shells, and is used to produce an original mold section. One or more master molds are formed from this original mold section by replication. Many identical replica molds are made by casting soluble material onto the master mold and removing them therefrom. The replica molds are coated with one or more layers which will form the hemispherical shell wall. The material coating the flat background around the hemispherical cavity is referred to as the flange and is removed to form free standing shells. In order to remove the flange material, the coated replica molds are overcoated with a soluble material which is etched away to the level of the flange. The remaining soluble material acts as a mask for the shell material when the flange material is etched away. The replica mold and overcoating body remain as a protective mask and are dissolved away to release the identical shell sections. These sections can be assembled to provide closed shells. Overlapping lips can be formed during flange removal so as to facilitate the assembly of the sections into the closed shells.
