    摘要: A process is disclosed of accelerating the preparation of a photographic emulsion containing tabular silver halide grains exhibiting a reduced degree of total grain dispersity. A dispersing medium is provided containing bromide ions, and a population of silver halide grain nuclei containing parallel twin planes is formed in the dispersing medium. A portion of the grain nuclei are ripened out, and then the silver halide grain nuclei containing parallel twin planes remaining are grown to form tabular silver halide grains. A polyalkylene oxide containing both hydrophilic and lipophilic block units is selected from among those known to be capable of reducing total grain dispersity when present during nucleation. However, in this process precipitation is accelerated while maintaining low dispersity of the total grain population by forming twin planes in the grain nuclei within the pAg and temperature boundaries of Curve A in FIG. 1 and by delaying introduction of the polyalkylene oxide block copolymer surfactant until after the silver halide nuclei containing twin planes have been formed.

    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.

    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.
