  • Patent number: 9825285
    Abstract: In an example of the method disclosed herein, a precipitate is formed in an aqueous mixture by mixing an SiOx precursor and an acid. The precipitate and a carbon material are added to a base, and the precipitate dissolves to form a solution having the carbon material therein. Hydrothermal synthesis is performed using the solution, and precursor nanostructures are grown on the carbon material. The precursor nanostructures on the carbon material are annealed so that the carbon material is removed and porous, one-dimensional SiOx (0<x?2) nanorods are formed.

  • Patent number: 9822868
    Abstract: A vent for a motor vehicle transmission includes a housing attached to a bell housing of the transmission. A plate is mounted in the housing, and the plate has an open position to enable heat to dissipate from the interior of the bell housing through an opening of the housing and a closed position to prevent debris or water from entering through the opening of the housing into the interior of the bell housing. The vent is a passive vent with a biasing mechanism that moves the plate to the open position when an interior temperature of the bell housing reaches a predetermined temperature threshold and moves the plate to the closed position when the interior temperature of the bell housing falls below the predetermined temperature threshold.
