A apparatus for detecting a high pressure condition within a high voltage vacuum device includes a microcircuit embedded within the vacuum containment that transmits a wireless signal upon detection of a high pressure condition and/or light generated by arcing between the electrical contacts of the high voltage device. The wireless signal can be transmitted via RF or optical means. The microcircuit is powered by energy sources produced within the vacuum device such as magnetic fields generated by current flow through the device, or light generated by arcing between the contacts. Alternatively, the microcircuit can be powered RF or optical signals transmitted to the microcircuit from outside the vacuum device.

A method for detecting a high pressure condition within a high voltage vacuum device includes detecting the position of a movable structure such as a bellows. The position at high pressures can be detected optically by the interruption of a light beam reflected by a hemispherically shaped reflector. The hemispherical reflector allows the source light fiber to oriented parallel to the detection light fiber, providing a more compact and efficient fiber routing.

A vacuum-type electrical switching apparatus () for high voltage electrical power. A vacuum pressure condition in a vacuum pressure space () surrounding electrical contact points () is monitored and movement of the contact points between open and closed positions is automatically prevented when the pressure exceeds a predetermined threshold in order to avoid destructive arcing between the points. A sensor () provides a vacuum signal () responsive to the vacuum pressure condition. A controller () automatically inhibits movements of the contact points when the vacuum signal indicates that the vacuum has degraded. A contactor () may be placed in series with power supply () and a solenoid () used to move the contact points, with the contactor being automatically opened by the controller in response to the degraded vacuum condition. An electromechanical opening inhibitor () may be energized by the controller to mechanically prevent the contact points from being moved in response to the degraded vacuum condition.

A method and apparatus for detecting a high pressure condition within an interrupter includes introducing high intensity ultrasonic sound into the outer wall of a vacuum interrupter through a sonic wave guide, then listening for the reflected and retransmitted response signals. The characteristics of the response signals are utilized to determine the pressure within the interrupter, and to determine when an unwanted high pressure condition exists.

A method for detecting a high pressure condition within a high voltage vacuum device includes detecting the position of a movable structure such as a bellows or flexible diaphragm. The position at high pressures can be detected optically by the interruption or reflection of light beams, or electrically by sensing contact closure or deflection via strain gauges. Electrical sensing is provided by microcircuits that are operated at high voltage device potentials, transmitting pressure information via RF or optical signals.

A method for detecting a high pressure condition within an interrupter includes measuring the intensity of light emitted from an arc created by contacts within the interrupter, comparing the measured intensity with a predetermined value, and providing an indication when the measured intensity exceeds the predetermined value.

A receiver hitch mounted bike rack with an anti-rattle mechanism includes a main tube that is received in the interior of a standard receiver hitch of a vehicle. The rack includes a pair of lateral wheel rails that each receive the front wheel or fork of a bike. An upright tube corresponding to each lateral wheel rail receives the bottom bracket of the bicycle. The bottom bracket rests in a groove on a top side of the upright tube, and the pedal arm is secured in the interior of the upright tube. One side of the upright tube, the side opposite the wheel, includes an elongated slot that accommodates the pedal of the bicycle.

A manually operated pallet changer system for use with automatic machine tools includes a pallet changer and a compatible machine tool mounted pallet receiver. The pallet changer includes a massive, floor supported base to which a cantilevered first platform is pivotally attached for rotation between a pallet-exchange position and a work-setup position. A second platform rests atop the first platform and supports a pair of work pallet guides. The two platforms are rotatably attached near their centers so that the pallet guides can be interchanged by rotating the upper platform about its center by 180&deg;. The configuration permits the platforms to be rotated as a unit away from a machine tool to the work-setup position. Work pallets are assembled and then the platforms are rotated together into the pallet-exchange position in which one of the pallet guides is aligned for transferring a work pallet to the machine tool mounted pallet receiver. The receiver includes an air bearing upper surface for simplifying the movement and positioning of a work pallet, a deployable clamping plate, and a pair of retractable locating pins for engaging openings on the underside of a work pallet to insure precision alignment during a machining operation.
