Abstract: A free gyro for use with a missile's seeker which allows the seeker to tr the target. The free gyro includes a support structure having a pair of roll axis forks which support a pitch gimbal and allow for rotational movement of the pitch gimbal about a pitch axis. Attached to the pitch gimbal is an outer gimbal support structure which includes a U shaped support member having a pair of support posts which support an outer gimbal ring and allow for rotational movement of the outer gimbal ring about the pitch axis. The outer gimbal ring supports and provides for rotational movement of an inner gimbal ring about an inner gimbal axis which is perpendicular to the pitch axis. The inner gimbal ring supports the free gyro assembly and allows the free gyro assembly to spin about a roll axis to stabilize the free gyro assembly. The free gyro assembly includes the optical system for the missile's seeker or tracking device and the support structure for the optical system.

Abstract: A reel payout system preferably for optical fiber guided tactical weapon tems to dispense a fiber data link or other strand member through a relatively small diameter exit aperture at a cone-shaped end of a housing containing the reel at relatively high velocities, the fiber dispensed from the reel generally perpendicular to the axis of rotation of the reel normal to the longitudinal axis of the housing.

Abstract: An armored optical fiber cable interconnection and method of making the irconnection with a self-sealing, low-strength joint with relatively low optical attenuation, has an inner fiber carrying jacket, an outer protective jacket, and an intermediate armored jacket of stranded material. The interconnection ends are assembled with a doubled layer of armored jacket over an intermediate protective jacket portion all sealed and held in place with a length of shrink tubing over the jackets and a retaining bead with an o-ring fitting over the assembly and against the shrink tubing over the retaining bead.

Abstract: A device for transmitting high pressure fluid between relatively rotating mbers. One of the members is equipped with a protruding axial cylindrical pipe having an accurately machined outside diameter and the other member has an accurately machined central bore receiving said pipe. By careful positioning and dimensioning of parts the pipe of the one member rotates in the bore of the other member without friction and with negligible loss of fluid.
