  • Patent number: 4068538
    Abstract: A platform stabilization system utilizing a small free running gyro, gimballed to the platform, as the reference element. Optical means are used to generate error signals in a torque free subsystem for sensing misalignment between the reference gyro and the platform. A system of magnetic rods and surrounding electrical solenoid coils are used to initially position the reference gyro. The reference gyro to platform gimbals are located within the structure of a second gimbal system mounting the platform to a pedestal mount. The close spacing of the axes from the platform yields a minimum swept volume of the pedestal in operation. Torque motors located in the pedestal are coupled to the platform gimbal by means of flexible cables. The motors are controlled by amplified signals from the optical error sensor signals. The result of this design is an extremely compact, high speed, low mass, low cost, stabilized platform system.

  • Patent number: 4050327
    Abstract: A connector to provide a fast-make coupling by which releasably to interconnect a control device to a push-pull control cable assembly. The control device has at least a sheath member and a plunger movable longitudinally within a passage through the sheath member. A connector housing is substantially permanently secured to the casing of the push-pull control cable assembly and releasably attached to the sheath member so as to be longitudinally aligned with the passageway therein. A shuttle plug, which is secured to the core of the push-pull control cable assembly is slidably received within the connector housing and the passageway in the sheath member to which the connector housing is releasably attached. A lug is presented from the plunger and interacts with a socket in the shuttle plug to effect an interconnection that is readily engaged and released, but only when the connector housing is not attached to the sheath member.

  • Patent number: 4011768
    Abstract: A manually controllable linkage is provided for selectively adjusting the swash plate of a reversible flow, variable displacement pump of a hydrostatic transmission. The linkage includes a speed and direction selecting part for selectively moving the swash plate so as to effect forward, reverse and neutral driving conditions in the transmission, and a neutral return part for overriding the speed and direction selecting part for quickly returning the swash plate to its position for effecting the neutral driving condition in the transmission. The speed and direction selecting part of the linkage includes input and output sections interconnected by a motion-moderating section which regulates or governs the maximum speed at which the output section and, hence, the swash plate may be moved regardless of the speed manually imparted to the input section.

  • Patent number: 4008623
    Abstract: A gyroscopic instrument which may be a compass includes a hollow sphere enclosing at least one motor-driven gyroscope and floating in an electrically conductive liquid within the inner surface of revolution of a vessel surrounding the sphere at a distance therefrom providing for a gap therebetween. A motor-driven pump circulates the liquid through an inlet of the vessel, through the gap, through an outlet of the vessel and through a passageway back to the pump. The surfaces confining the gap have pairs of opposite conductive electrode portions for conducting electrical energy to the motor-driven gyroscope or gyroscopes. The liquid circulating through the gap exerts a bearing pressure on the sphere holding it spaced from the inner surface of the vessel. For this purpose the gap has a relatively narrow bearing zone communicating with the inlet and a relatively wider zone communicating with the outlet.

  • Patent number: 4005614
    Abstract: A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly. The system employs a motion conversion unit at either or both control and controlled station, said units serving to convert rotary motion into linear motion, and vice versa. That is, a force transfer shaft is rotatably mounted in the housing of the motion conversion unit to receive, or impart, rotary motion, and the core element of the push-pull control cable assembly -- which receives, or imparts, linear motion -- extends into, or through, the unit in transversely spaced relation with respect to the shaft. That portion of the normally flexible core element which extends into, or through, the unit is made rigid to impart columnar strength. A crosshead is secured to the rigidified portion of the core element and is slidably received within a first guideway presented from the housing to minimize lateral loading to the rigidified portion of the core element.
