  • Patent number: 11879541
    Abstract: A gearbox including a gear and a gutter. The gear is rotatable about a rotational axis in a rotational direction. The gear has a radial direction and an axial direction, and the gear expels oil radially outward when the gear rotates. The gutter is positioned radially outward of the gear in the radial direction of the gear to collect oil expelled by the gear when the gear rotates. The gutter includes an axial surface, a plurality of radial surfaces including a first radial surface and a second radial surface, and at least one opening to allow the oil collected in the gutter to flow therethrough. Each of the first radial surface and the second radial surface is oriented in a direction intersecting the axial surface, and the at least one opening is formed on both the axial surface and one of the first radial surface and the second radial surface.

  • Patent number: 11839590
    Abstract: A flurbiprofen axetil emulsion for injection can be prepared by specific stepwise addition of an oil phase to a water phase with shear mixing under the protection of nitrogen gas to obtain an emulsion. The oil phase includes flurbiprofen axetil, an oil phase solvent, an emulsifier, and a stabilizer, and the water phase includes water for injection and/or an osmotic pressure regulator. In the presence of a stabilizer in the oil phase, the emulsion can improve the emulsification effect by using the stepwise emulsifying technique for the oil phase, so that the obtained flurbiprofen axetil emulsion for injection has more uniform particle size, higher drug entrapment efficiency, and better targeting of the drug to the wounded tissue.
