摘要:
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.

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.
摘要:
A vertical gyroscopic reference system consists of a gimballed platform solid with a stator in the form of a hollow spherical chamber in which a substantially spherical gyro rotor revolves, the rotor being both driven and supported by air pressure, and having a pressure-fed hole through its spin axis which cooperates with ports in the stator to provide signals to a pair of pneumatic actuators which slave the platform to follow the gyro rotor.

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.
