7570471, Aug 4, 2009

Filed:

Feb 20, 2007

Appl. No.:

11/676532

Inventors:

Helmut Weiher - Burton OH, US
Jeffrey W. Patterson - Oberlin OH, US
Richard C. Fleischer - South Euclid OH, US

Assignee:

Utility Relay Company - Chagrin Falls OH

International Classification:

H02H 3/001

US Classification:

361 64, 361 62

Abstract:

A zone-selective-interlocking system for an electrical power distribution system that has at least one upstream breaker and at least one downstream breaker is provided. Each breaker in the power distribution system has a zone-selective-interlocking circuit that includes a zone-selective-interlocking-input circuit and a zone-selective-output circuit. The zone-selective-interlocking system also includes a monitoring device to monitor the voltage sent from the zone-selective-interlocking-output circuit of the at least one downstream breaker to the zone-selective-interlocking-input circuit of the at least one upstream breaker and determine whether there is a proper or improper connection between the upstream and downstream breaker and whether the downstream breaker is sending a restraint signal to the upstream breaker.

H02H 9/08

US Classification:

361 96, 361 42

Abstract:

A circuit protection system includes a normal mode and a maintenance mode. A current sensor senses current in the circuit. An enclosure includes an access panel that is movable between a closed position and open position. A circuit breaker is mounted within the enclosure. An electronic trip unit is in communication with the current sensor and controls interruptions of the current by the circuit breaker based on a trip setting. An interface device is accessible when said access panel is closed and allows selections of the normal and maintenance modes. A display, which is in communication with both of the user interface device and the electronic trip unit, monitors the interface device and transmits data to the trip unit that is based on the selected mode. The display receives data from the trip unit and displays information based on the received data. The display is viewable when the access panel is closed.

Abstract:

A component multi-necked string-instrument is disclosed. At least two instruments are flexibly connected to enable multiple instrument playing with fluidity and ease. The instruments are reverse-strung, stream-lined, having conventional tunings means angularly recessed rearward of the bridge section. Electrical control means are likewise recessed. A limited headstock is also provided for string anchoring, balance and playing ease.
