Title: Leakage current protection device adapted to a wide variety of domestic and international applications
Inventor: LEGATTI RAYMOND H
IPC: H02H1/06
Filed: 1993-03-31
Granted: 2005-02-15
Abstract: A leakage current protection device, such as a ground fault circuit interrupter (GFCI), is provided that can be used in single phase or polyphase systems, with a range of input voltages from 70 to 264 volts AC, frequencies of 50 or 60 hertz, and ground fault trip currents of 6 to 30 milliamperes. A leading power factor circuit is connected to the secondary winding of the GFCI differential transformer to permit the magnetic circuit to respond to pulsating DC signals. Provision is made for continuing to provide GFCI protection in the event of an open neutral lead, with a timing circuit to prevent current flow to the ground lead until current flow in the neutral lead is completely discontinued.  Various types of circuit interrupting devices, such as a circuit breaker or a power converter, may be selectively utilized.

Granted: 2001-08-07
Abstract: The present invention relates to an optical fiber cable which includes magnetically locatable materials within the sheath system thereby allowing the cable to be located after it has been buried. More specifically, at least a portion of the magnetic particles are purposely oriented in a particular alignment based on their magnetic properties. Such an arrangement not only allows the generation of a detection signal which is distinguishable from that generated by a solid metallic pipe, but also can greatly enhance the level of the detection signal generated. The enhanced detection signal provides for more reliable detection of buried all-dielectric cables and also allows them to be located even when buried at greater depths, such as six feet or more. In specific embodiments of the present invention, the magnetic particles may be aligned and/or magnetized either longitudinally, vertically or transversely relative to the cable. Additionally, these various directions of alignment and magnetization may be alternated along the length of the cable to further enhance the detection signal generated in order to establish a means of accurately and cost-effectively locating communications cable after they are buried.
