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.

An erector for holding a spin axis of a gyro rotor in the vertical direction used in a gyroscopic horizon or gyro vertical which comprises a gyro casing incorporating therein a gyro rotor rotating at high speed, a spin axis of the gyro rotor being held substantially in the vertical direction, first supporting member for rotatably supporting the gryo casing around a first horizontal axis which is perpendicular to the spin axis and second supporting member for rotatably supporting the first supporting member around a second horizontal axis which is perpendicular to both the spin axis and the first horizontal axis is disclosed, which includes a base plate, a motor mounted on the base plate, a rotation receptacle container having an annular shape cavity and rotated at low speed by the motor, and liquid charged into the annular shape cavity of the rotation receptacle container, the base plate being mounted on the gyro casing such that the rotation axis of the rotation receptacle container and the spin axis of the gyro rotor become parallel to each other.

A processing station for registering a piece of passenger's luggage for a trip, wherein the processing station comprises: an injector for receiving the piece of luggage associated with the passenger: at least one sensor associated with the injector, the at least one sensor, in combination with at least the floor of the injector, creating a zone around the piece of luggage; and a controller associated with the sensor being adapted to: monitor, via the at least one sensor, intrusions through the zone to determine one or more of whether a predetermined limit on dimensions of the piece of luggage has been exceeded or whether a foreign object has intruded the zone from outside, and allow further processing of the piece of luggage only if no intrusion of the zone is detected; and wherein the controller adjusts the area of the zone to accommodate different sizes of luggage.

An air erected gyro includes an erection-force producing air stream and gravity-responsive valve means whose gate portion is movable across the air stream so as to vary the erection force magnitude. Also included is a compensator means connected for movement with the gate and for also confronting the air stream so as to at least partially counteract air stream induced horizontal coercive effects on the valve means position.

A rate gyro providing a fluidic output signal corresponding to the yaw rate of a vehicle, for use in an adaptive steering system. The gyro rotor is hydraulically supported and spun via tangential reaction jets connected in parallel with flapper nozzles situated to provide both a differential pressure signal corresponding to yaw rate and a centering spring force creating gyro natural frequencies well above the disturbance frequencies encountered. The support, jet, and nozzle fluid supplies are all incorporated into the power steering supply circuit.
摘要:
A gyroscope and spin-up system in which the gyroscope rotor is rotated by fluid from a spin-up device. Fluid pulses are generated as a result of fluid from the spin-up device striking pulse-generating fluid-receiving areas provided on the rotor. The number of pulses produced depends upon the speed of the rotor. The pulses act on a resonant means which operates at a predetermined rotor speed to cut off the supply of fluid to the spin-up system.

AN ERECTING SYSTEM FOR A VERTICAL GYROSCOPE USEFUL IN AIRCRAFT ATTITUDE-INDICATING INSTRUMENTS AND THE LIKE. A GIMBAL-SUPPORTED HOUSING IN THE GYRO ENCLOSES A GYRO ROTOR, AND IS SUPPLIED WITH AIR WHICH DRIVES THE ROTOR. AIR IS EXHAUSTED FROM THE HOUSING THROUGH FOUR DOWNWARDLY DIRECTED OUTLET PORTS AT THE CORNERS OF THE HOUSING UNDERSURFACE. CONTROL VANES ARE PENDULOUSLY SUPPORTED ON THE HOUSING AND EXTEND BENEATH THE OUTLET PORTS TO INTERCEPT THE EXHAUST AIR STREAMS AND THEREBY IMPART TORQUES TO THE GYROSCOPE TENDING TO ERECT THE ROTOR SPIN AXIS A SUBSTANTIALLY VERTICAL POSITION. AIR PASSAGES THROUGH OUTER AND INNER GIMBALS SUPPLY AIR TO THE HOUSING, AND THE PASSAGES ARE CONFIGURED SO A PRESSURE DIFFERENTIAL EXISTS ACROSS A ROTARY CONNECTION BETWEEN THE INNER AND OUTER GIMBALS. A PRESSURE DROP OCCURS GOING FROM THE OUTER GIMBAL TO THE INNER GIMBAL OR ROTOR HOUSING, WHEREBY AIR DELIVERED TO THE ROTOR DOES NOT TEND TO LEAK OUTWARDLY THROUGH THE ROTARY CONNECTION AND THE NEED FOR BULKY AND FRICTIONPRODUCING SEALS IS ELIMINATED.
