  • Reinforced soft substrate with hardcoat
    Patent number: 10670060
    Abstract: In one example, an article including a soft substrate defining at least one of a first outer perimeter of the substrate or an aperture extending through the soft substrate defining a second outer perimeter of the aperture; a hard coating on the outer surface of the soft substrate; and at least one reinforcement member extending through the soft substrate at a location adjacent to at least one of the first outer perimeter or the second outer perimeter, wherein the at least one reinforcement member increases resistance to compression of the soft substrate at the location of the at least one reinforcement member.

  • Bearing race cooling
    Patent number: 10663005
    Abstract: A cooling architecture can include a longitudinally extending radially inner shaft, a radially outer support, and a bearing assembly. The longitudinally extending radially inner shaft can include an inner race. The inner race can define an inner circumferential chamber configured to carry an inner working fluid. The radially outer support can include an outer race. The bearing assembly can include a plurality of roller bearings disposed radially between the inner race and the outer race. The bearing assembly can be configured to radially align the inner shaft with respect to the outer support.
