Abstract: A method and apparatus are provided for displaying image and facsimile data on a host-based application display. A host computer generates control and download command data for displaying the image or facsimile data. The image and facsimile data is processed by a non-programmable-terminal (NPT) or a programmable work station (PWS) for presentation of a display screen. When a user requests another function, the NPT or PWS stores image information and sends image information to the host computer. The save image information includes cache image counter data, scaling and viewed image screen location data that is used to restore the displayed image and facsimile data when the user returns to the previous function.

Abstract: Breaks in the bare neutral conductor of an underground electric cable can be located by applying an alternating signal across the neutral conductor and a phase conductor at one end of the cable. The neutral and phase conductors are connected together at the other end of the cable. The electrical potential of the alternative signal is measured at a series of spaced apart points on the earth's surface along the cable's path. The potential between points over a cable section with an open in the neutral conductor will be about two orders of magnitude greater than the potential between points above good cable section.
