摘要:
A shunt connected energy stabilizing system with isolation switching for providing stored energy to loads or to a utility or industrial electrical distribution system or source of electrical power. An energy backup and recovery system stores energy in a superconducting magnet and releases the energy to a real power/reactive power (VARs) generator which in turn delivers energy to either the loads or to both the loads and the source of electrical power. During periods of voltage sag or power outage, an isolation switch provides a way for isolating the loads from the source of power so that energy can be supplied to the loads only to provide "ride-thru". In effect, the isolation of the load sheds this load from the power system, thereby boosting the rest of the electrical distribution to a level so that other loads on the power system are not disturbed by the voltage sags. By supplying energy to the loads only, small superconducting magnets can be used thereby providing economic and size advantages. The isolation switch also provides a smooth transition from the real power generation to the VAR compensation mode, and vice versa. Additionally, the isolation switch can direct stored energy to both the electrical system and to the loads at the same time.

A multicolor photographic element capable of forming a viewable reversal dye image is disclosed comprising a support and, coated on the support, a blue recording yellow dye image forming layer unit, a green recording magenta dye image forming layer unit, and a red recording cyan dye image forming layer unit, each of the layer units containing in at least one layer a silver halide emulsion having a grain halide content of from 0 to 5 mole percent chloride, from. 0.5 to 20 mole percent iodide, and from 80 to 99.5 mole percent bromide, based on total silver.The photographic element is characterized in that at least one of the silver halide emulsion layers is a tabular grain emulsion layer in which the coefficient of variation of the tabular grain emulsion is less than 15 percent, based on the total grain population of the emulsion, and the total grain population of the tabular emulsion consists essentially of tabular grains having a mean thickness of less than 0.3 .mu.m and a mean tabularity of greater than 25.
摘要:
Novel elements for the analysis of liquids which contain interferents for an analyte assay are described. Interference is reduced in multizone elements by the presence of an interferent-removing zone between the point of introduction of the liquid and the assay-indicator zone wherein the interferent-removing zone comprises a discontinuous phase within a continuous phase. An interferent-removing material is present in the discontinuous phase and the continuous phase is permeable to the analyte, its products and/or the liquid being analyzed.

摘要:
A superconducting energy stabilizer having multiple load connections employs DC-DC conversion. A discharging DC-DC converter removes stored energy from a superconducting inductive energy storage device or superconducting magnet and delivers the energy to an energy storage cell for use by a load or a utility or industrial electrical distribution system. Regenerated energy can also be retrieved from regenerative type devices and stored in the superconducting magnet for later use. A charging DC-DC converter provides this function. The charging DC-DC converter and the discharging DC-DC converter as well as an off-the-line power supply which provides energy for storage in the superconducting magnet can operate simultaneously under the control of a control system.
