  • Seal means for a self-aligning bearing and method of making the same
    Patent number: 4089095
    Abstract: The invention contemplates elastomeric-seal application to the so-called plain-spherical variety of self-aligning bearing wherein the outer ring is the product of a swaging operation which causes it to conform its cylindrical bore to a spherical surface at sliding interface with the spherical convex outer surface of an inner-bearing member. Specifically, in the machining of the swaged ring to its ultimate O.D. and other specified dimensions, a deformable axially extending lip is created, in conjunction with an undercut counterbore, at the axial end to be sealed; an elastomeric O-ring is fitted to the counterbore, and the lip is coined-over into retaining and preloading relation with the O-ring.

  • Phasing control for convertiplane
    Patent number: 4088284
    Abstract: A convertiplane having control apparatus for modification of the control signals during the course of transition in either direction between a helicopter mode and the aircraft mode. The convertiplane has at least one pylon rotatable about a lateral axis, positioned parallel to the longitudinal axis of the convertiplane to a position normal to the axis for selective operation in the airplane mode and in the helicopter mode, respectively. Rotor blades are provided on each pylon with a control linkage responsive to pilot input in the helicopter mode to vary the collective and cyclic pitch of the rotor blades. Drive linkages are provided to change the pylons from one mode position to the other mode position. Control linkages are operatively associated in synchronism with the drive linkages to alter the authority of the pilot control to change the pitch of the blade during transition.

  • Mast torque metering system
    Patent number: 4083518
    Abstract: In a helicopter, torque display for a main rotor mast is mounted and connected to be driven from a power source at its base and connected to a main rotor at its tip. A reference member secured inside the main mast at the tip thereof depends freely and extends coaxially the length of the mast to a point adjacent the base thereof. A separate index is carried by the reference member adjacent to the base and by the main rotor mast adjacent to its base. A pick-off senses rotational movement of one index relative to the other and provides for actuation of a torque indicator for the pilot of the helicopter.

  • Low-friction fabric bearing
    Patent number: 4074512
    Abstract: Improved wear and load-carrying properties result for a resin-impregnated fabric bearing wherein the bearing surface includes, as the most significant fabric component, a yarn which is a compounded bundle of sized TFE filaments and sized filaments of high-temperature nylon, in the proportion of at least no more than 50 percent TFE by volume. The yarn is loosely twisted, to the extent that after construction of a fabric with said yarn, the yarn is fully washable, to remove the sizing, down to the innermost filaments. This enables full impregnation of the fabric with synthetic resin, and curing in substantially intimate and continuous and void-free relation of the resin to all filaments within the yarn of the fabric.
