    Patent number: 11236779
    Abstract: A high-speed shaft assembly includes a shaft of a first material and an outer member of a second material disposed about the shaft, the shaft or outer member being rotatable about an axis. The two materials have substantially different coefficients of thermal expansion such that the shaft and/or the outer member is relatively displaceable along the axis at temperatures over 120° C. and less than ?18° C. A bearing inner ring is disposed about the shaft and has an outer race which is a cylindrical surface or an annular groove. A bearing outer ring is disposed about the inner ring and coupled with the outer member. The outer ring has an outer race which is the other one of the cylindrical surface and the groove. A plurality of balls disposed between the races are displaceable axially along the cylindrical race surface during relative displacement of the shaft and outer member.

  • Seal
    Patent number: 11204099
    Abstract: A seal that enables an enclosure to be sealed and to keep an air pressure balance between an internal space within the enclosure and an external space outside the enclosure in such a way that water ingress into the enclosure is hindered in a predictable manner. This is accomplished by providing a seal having at least one small diameter tube with at least an inner surface being hydrophobic, oleophobic or omniphobic. The seal is mounted in the enclosure between the inner and outer space. To further avoid small particle contaminants to enter and go through the at least one small diameter tube, it is preferable to have a small diameter tube with curves and bends, and it will still allow an airflow through it if there is an air pressure imbalance.
