  • Patent number: 10017397
    Abstract: A semiconductor material basically consists of titanium oxide, with the special feature of being like nanostructures, which gives special physicochemical properties, with ability to disperse and stabilize metal particles with high activity and selectivity in catalytic processes mainly. The process of producing the semiconductor material includes adding a titanium alkoxide to an alcoholic solution, adding an acid to the alcoholic solution, controlling the pH from 1 to 5; subjecting the acidic solution to agitation and reflux conditions at 70 to 80° C.; stabilizing the medium and adding bidistilled water in a water/alkoxide molar ratio of 1-2/0.100-0.150, continuing with reflux until gelation; aging the gel for 1 to 24 hours for complete formation of the titania; drying the titania nanostructured at of 50 to 80° C. for about 1 to 24 hours, and subjecting the dried titania to a calcination step at 200 to 600° C. for 1 to 12 hours.

  • Patent number: 9580332
    Abstract: A nanostructured titania semiconductor material termed TSG-IMP having a predetermined crystal size is produced by a sol-gel method by adding a titanium alkoxide to an alcoholic solution, adding an acid to the alcoholic solution, subjecting the acidic solution to agitation under reflux conditions; stabilizing the medium and adding bidistilled water under reflux until gelation; subjecting the gel to aging until complete formation of the titania which is dried and calcined.

  • Patent number: 9182074
    Abstract: The cap holder with magnet according to the present invention includes a base that serves to place caps, hats, visors, or articles having similar characteristics for their care, display, storage, or to keep them in order. A magnet is attached to the base or bottom section of the base. A protrusion is formed on the back section of the base. Inward curves are formed on the back section of the base. A hook may also be attached to the back section of the base to allow to vertically use the cap holder with magnet.

  • Patent number: 9150972
    Abstract: Disclosed is a Fuel Augmentation Support System (“FASS”). The disclosed FASS herein is useful to support a multitude of electrolysis cell composition and designs. It provides a system which supports an uncontaminated electrolysis process via the prohibition of other elements from intermingling with the electrolytic fluid, without creating excess positive or negative pressures in a FASS operations, an example of producing gas using the electrolysis of distilled water combined with a catalyst of potassium Hydroxide will be used since it is a method to generate a combustible gas used to enhance the combustion of practically any fuel. The FASS exploits an efficient utilization of electrons generated between the electrolysis electrodes in order to produce gas and achieve it's goals.

  • Patent number: 7823879
    Abstract: An apparatus for deskewing a media sheet includes a sheet feed system for transporting the media sheet along a media feed path in a media feed direction. A split alignment gate is positioned to intersect the media feed path. The split alignment gate subjects the media sheet to a deskewing force, wherein an amount of the deskewing force is determined based on a width of the media sheet in a direction transverse to the media feed direction.

  • Patent number: 7731176
    Abstract: A sheet picking system for picking a sheet of media includes a power source having a driveshaft. A first housing arm containing a drive gear is drivably coupled to the driveshaft. The drive gear defines a first pivot axis for the first housing arm, wherein the drive gear is driven by the driveshaft to rotate about the first pivot axis. A second housing arm contains an intermediate gear, a transmission device, and a pick roller. The transmission device is configured to rotatably couple the intermediate gear to the pick roller. The intermediate gear is positioned to be meshed with the drive gear. The intermediate gear defines a second pivot axis for the second housing arm. A link mechanism pivotably couples the first housing arm at the first pivot axis to the second housing arm at the second pivot axis.
