  • Publication number: 20240141983
    Abstract: Systems are provided for a gearset for a vehicle transmission. In one example, a system includes a shaft comprising one or more lubricant holes oriented radially within the shaft, and one or more gears positioned radially around a central axis of the shaft. The system further includes a ring positioned circumferentially around the shaft. The ring is shaped with a radially extending portion and an axially extending portion, wherein the radially extending portion may direct lubricant flow from the radially oriented lubricant holes toward the axially extending portion, and the axially extending portion directs lubricant flow from the lubricant holes in an axial direction towards the one or more gears. The axially extending portion and radially extending portion form a cut in the ring.

  • Patent number: 10288482
    Abstract: Technologies for detecting absorption of electromagnetic radiation traveling through a measurement volume of interest are described herein. In a general embodiment, a laser is used to emit electromagnetic radiation through the measurement volume where absorption is desirably detected. An optical collector receives a portion of the radiation and directs a first fraction of the portion back to a gain medium of the laser, where the radiation is amplified and emitted again, and directs a second fraction to an optical sensor that can detect absorption in the measurement volume based upon attenuation of energy of the radiation. As the radiation feeds back to the gain medium and is emitted again, energy at attenuated wavelengths is amplified less than at other wavelengths. Thus, attenuation of energy of the radiation due to absorption in the measurement volume is cumulative, and relatively small absorptions are amplified, allowing smaller absorptions to be detected more easily.

  • Patent number: 9598644
    Abstract: A method of hydrogenation utilizing a reactant gas mixture comprising a carbon oxide and a hydrogen agent, and a hydrogenation catalyst comprising a mixed-metal oxide containing metal sites supported and/or incorporated into the lattice. The mixed-metal oxide comprises a pyrochlore, a brownmillerite, or mixtures thereof doped at the A-site or the B-site. The metal site may comprise a deposited metal, where the deposited metal is a transition metal, an alkali metal, an alkaline earth metal, or mixtures thereof. Contact between the carbon oxide, hydrogen agent, and hydrogenation catalyst under appropriate conditions of temperature, pressure and gas flow rate generate a hydrogenation reaction and produce a hydrogenated product made up of carbon from the carbon oxide and some portion of the hydrogen agent. The carbon oxide may be CO, CO2, or mixtures thereof and the hydrogen agent may be H2. In a particular embodiment, the hydrogenated product comprises olefins, paraffins, or mixtures thereof.

  • Patent number: 9126833
    Abstract: A method for the rapid and continuous production of crystalline mixed-metal oxides from a precursor solution comprised of a polymerizing agent, chelated metal ions, and a solvent. The method discharges solution droplets of less than 500 ?m diameter using an atomizing or spray-type process into a reactor having multiple temperature zones. Rapid evaporation occurs in a first zone, followed by mixed-metal organic foam formation in a second zone, followed by amorphous and partially crystalline oxide precursor formation in a third zone, followed by formation of the substantially crystalline mixed-metal oxide in a fourth zone. The method operates in a continuous rather than batch manner and the use of small droplets as the starting material for the temperature-based process allows relatively high temperature processing. In a particular embodiment, the first zone operates at 100-300° C., the second zone operates at 300-700° C., and the third operates at 700-1000° C., and fourth zone operates at at least 700° C.
