International Classification:

G01R 1100

US Classification:

324 74, 324142, 702 60

Abstract:

A metering module for use in a power circuit monitoring system including a circuit monitor having a processor for processing data related to power signals, said metering module comprising at least one sensor for sensing a predetermined property of a power signal and for producing a corresponding sensor signal, and a modular metering circuit for producing data corresponding to said sensor signal for input into said circuit monitor, wherein said metering module is selectively detachable and replaceable relative to said circuit monitor to permit one or more of testing, calibration and repair of said metering module thereby minimizing any interruption in operation of said circuit monitor.

Abstract:

A method for time reference compensation in a power metering system, the method comprising monitoring a time-dependent characteristic of incoming AC power over a predetermined local time interval, comparing the monitored characteristic over the predetermined local time interval with the expected value of the characteristic based upon the nominal frequency of the AC power, and calculating a correction to one or more of local real-time and time-based measurements of the power metering system, based on the comparing.

B67D 7/06

US Classification:

220200, 222183

Abstract:

A closure member for a shroud includes an annular wall and no more than one raised surface, interior of the annular wall, which extends upwardly beyond any other component of the closure member. The raised surface is configured to inhibit movement of a container both longitudinally and laterally when the annular wall is attached to a shroud with a container disposed therein.

International Classification:

B05D 306

US Classification:

427 39

Abstract:

A D. C. glow discharge is applied to a heated glass substrate coated with a conductive layer in the form of a pattern in an evacuated chamber, to which chamber certain amounts of oxygen and a volatile tin composition have been added. A glass substrate is produced which is coated with a patterned, transparent, conductive coating of tin oxide, wherein the surface region of the glass has been depleted of alkali metal ions.
