摘要： A gyrostabilizer without a physical shaft or axle is constructed. The stabilizer has dual counter-revolving concentric rings filled with weights such as spherical balls that are propelled in orbital fashion by fluid pressure or electromagnet propulsion. The diameter of the concentric ring can vary from a few inches to more than ten (10) feet. Without an axle or shaft the weight of the gyrostabilizer is shifted to the perimeter where most of the momentum is generated at a fraction of the weight of gyrostabilizers that spin on an axle. Also without an axle or shaft the space between the center of revolution and the revolving balls is usable or void. When properly mounted in a vehicle or structure unsteadiness such as tremors, vibrations, sway, pitch, roll, yaw can be dampened.

摘要： The invention is a floated gimbal instrument platform that provides a stable optical path for optical instruments. The instrument platform has an outer vessel with a transparent viewing port, an inner vessel also with a transparent viewing port, a transparent suspending fluid filling the outer vessel and in which the inner vessel floats in neutral buoyancy, an optical instrument secured inside the inner vessel, spacing studs which centrally position the inner vessel within the outer vessel, and jets which align the second viewing port with the first viewing port, the jets being used to rotate the inner vessel in the suspending fluid. Any misalignment between the viewing ports can be compensated by rotating the inner vessel and any translational forces applied to the platform is dampened by the fluid, thereby eliminating jitter.

摘要： An agitator includes a multi-freedom electric motor having a broad operational range. The electric motor includes a spherical rotor, a plurality of magnets disposed on an outer surface of the rotor with polarities of the respective adjacent magnetic poles being different from one another, a stator provided along the outer surface of the rotor, and a plurality of magnets opposed to the magnets disposed on an inner surface of the stator. The rotor is supported by a spherical bearing provided on the stator. Either the magnets on the rotor or the magnets on the stator are electromagnets. Electric currents are supplied to the electromagnets as controlled by a controller. In one form of the agitator, the electric motor is disposed at the bottom of a container and the bottom end of a screw is connected to the spherical rotor of the motor. The top end of the screw is supported by an arm pivotably mounted to the container. In this way, the motor can rotate the screw about its own axis and revolve the screw around the container. In another form of the agitator, agitating elements are fixed to the rotor itself, and these agitating elements are moved to agitate material charged into the agitator.

摘要： A control moment gyroscope for providing directional control in a spacecraft. The control moment gyroscope has a rotor which is electrostatically or magnetically supported within a gimbal housing so as not to touch any of the interior surfaces of the housing. The housing is mounted on a gimbal support which in turn is mounted on the spacecraft. Connected to the gimbal housing is a torque motor which rotates the housing around a gimbal axis. In order to induce a direction changing torque on the spacecraft, the rotor is first spun about its rotor axis. A torque is then induced on the rotor about the output axis. This induced torque will cause the rotor to precess about the gimbal axis which the torque motor follow. The torque induced around the output axis is transferred directly to the spacecraft.

摘要： Suspension stiffness about the input axis of a gyro is increased by selectively disabling suspension legs when the gyro float exceeds a predetermined deviation away from the equilibrium position. Float position may be measured directly or inferred from monitoring currents in the electromagnetic suspension system. Suspension legs are re-energized when the float returns to within the predetermined deviation from the equilibrium position.

摘要： A gyroscope system comprises a dual-axis rate gyroscope (1) including angle pick-offs and rotor torque applying device (5), and a control circuit (3) arranged to supply a control signal to the rotor torque applying device (5) in accordance with the output angle sensed by the angle pick-offs. The system further comprises an angular acceleration sensor (2) which is independent of the dual-axis rate gyroscope and is arranged to output a signal to the control circuit (3). The signal modifies in accordance with the sensed angular acceleration the control signal supplied to the torque applying device (5). Preferably the angular acceleration sensor (2) forms part of a guidance system independent of the dual-axis rate gyroscope (1).
