摘要： A method of making a monodisperse regular grain silver halide high bromide emulsion is described comprising precipitating regular silver halide grains comprising greater than 50 mole percent bromide, based on total silver, in a reaction vessel, and adding to the reaction vessel before or during precipitation a disulfide compound represented by the following formula (I): where Y and Z are H atoms or substituents, which may be connected to form a carbocyclic or heterocyclic ring, X is —O—, —NH— or —NR—, where R is a substituent; M is —H— or a cationic species; and L is a linking group, where p is 0 or 1. The invention further provides a silver halide emulsion prepared by the method, and a photographic element comprising a silver halide emulsion prepared by the method. The use of water soluble disulfide compounds of the above formula in the preparation of regular grain high bromide emulsions provides the antifoggant advantages of water soluble disulfide compounds in a monodisperse emulsion, while avoiding the problem of large grain contamination in such emulsions.

摘要： A method for forming a photographic element includes steps of heating an emulsion containing grains of a radiation sensitive silver haloiodide to form a first melt, heating an emulsion containing grains of a silver salt effective to enhance the photographic properties of the silver haloiodide emulsion to form a second melt, and coating the first and second melts onto a photographic support to form an image recording layer. The silver salt grains are substantially insensitive to radiation at wavelengths at which said silver haloiodide grains are sensitive. The coating step is preferably carried out by blending the first and second melts together, then immediately coating the silver haloiodide emulsion onto the support. In a preferred embodiment, the silver salt is essentially silver chloride in the form of relatively fine cubic grains, and the silver haloiodide is in the form of tabular grains larger than the cubic grains. The foregoing procedure unexpectedly improves the speed of the resulting photographic element. For color reversal photographic elements, the melt containing the fine silver salt grains is conveniently the coupler melt.

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.
摘要翻译：一种分流连接的能量稳定系统，具有隔离开关，用于向负载或公用事业或工业配电系统或电力源提供储存的能量。能量备份和恢复系统将能量存储在超导磁体中，并将能量释放到实际的功率/无功功率（VAR）发生器，该功率/无功功率（VAR）发电机又向负载或负载和电源供电。在电压骤降或停电期间，隔离开关提供了将负载与电源隔离的方式，以便只能向负载提供能量以提供“穿越”。实际上，负载的隔离使得该负载从电力系统中脱离，从而将其余的电气分配提升到一个水平，使得电力系统上的其它负载不会受到电压骤降的干扰。通过仅向负载提供能量，可以使用小型超导磁体，从而提供经济和尺寸的优点。隔离开关还提供从实际发电到VAR补偿模式的平滑过渡，反之亦然。此外，隔离开关可以将存储的能量同时引导到电气系统和负载。
