Filed:

Jun 5, 2001

Appl. No.:

09/874690

Inventors:

William D. McDaniel - Oakview MO 64118

Timothy J. McDaniel - Oakview MO 64118

International Classification:

G05F 170

US Classification:

323211

Abstract:

An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation which is capable of indicating a level of reactive power drawn by the load and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. A first embodiment of the system is based on a measured level of current and the effect on the measured level of current of adding compensating capacitors of selected capacitances to the power line. A second embodiment of the system is based on a measurement of phase angle of the power drawn and the addition of a calculated combination of capacitors to the power line to compensate for a measured level of reactive power.

An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation which is capable of indicating a level of reactive power drawn by the load and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. In particular, the system measures the phase angle of the power drawn and calculates a combination of capacitors to connect to the power line to compensate for a measured level of reactive power.

International Classification:

G05F 1/70

US Classification:

323211

Abstract:

An automatic power factor correction system, for an electrical power installation drawing varying levels of reactive power, measures an electrical parameter of the power drawn by a load of a power installation using a power measurement integrated circuit, the parameter being capable of indicating a level of reactive power drawn by the load, and couples a combination of capacitors to the power line to compensate for the level of reactive power indicated by the electrical parameter measured. In a first embodiment of the invention, the combination of power factor compensating capacitors is calculated from a signed value of reactive power drawn by the load. In a second embodiment, the compensating capacitor combination is calculated from a value of power factor for the load which is calculated from a ratio of an active power value to an apparent power value.

Inventors:

- St. Louis MO, US
William Mark McDaniel - Wildwood MO, US

International Classification:

F16L 27/11

Abstract:

An expansion joint fitting for conveying liquid includes a radially inner bellows defining a liquid-conveying passage for conveying liquid between the first and second longitudinal ends of the expansion joint fitting. A radially outer bellows is disposed radially outward from and extending around the radially inner bellows. An annular plenum is defined between the radially inner bellows and the radially outer bellows.

Abstract:

A flanged fitting includes an annular fitting flange having an annular end face. A glass liner lines a radially inner annular portion of the annular end face of the annular fitting flange. A radially outer annular portion of the annular end face of the annular fitting flange is free from the glass liner. The radially inner annular portion and the radially outer annular portion of the annular end face of the annular fitting flange define an annular gasket abutment face configured to seat a gasket thereon. An annular gasket includes an annular gasket layer. The annular gasket layer includes a radially inner annular gasket segment including a first material suitable for forming a liquid-tight seal with an opposing flange. A radially outer annular gasket segment surrounds the radially inner annular gasket segment. The radially outer annular gasket segment is fire-rated for forming a fire-rated seal with the opposing flange.
