摘要:
An energy management system uses an expert engine and a numerical solver to determine an optimal manner of using and controlling the various energy consumption, producing and storage equipment in a plant/communities in order to for example reduce energy costs within the plant, and is especially applicable to plants that require or that are capable of using and/or producing different types of energy at different times. The energy management system operates the various energy manufacturing and energy usage components of the plant to minimize the cost of energy over time, or at various different times, while still meeting certain constraints or requirements within the operational system, such as producing a certain amount of heat or cooling, a certain power level, a certain level of production, etc. In some cases, the energy management system may cause the operational equipment of the plant to produce unneeded energy that can be stored until a later time and then used, or that can be sold back to a public utility, for example, so as to reduce the overall cost of energy within the plant.

摘要:
A dye-donor element including a dye-donor layer is described, wherein the dye-donor element includes a stick preventative agent. The dye-donor element is capable of printing an image on a receiver element at a line speed of 2 ms/line or less while maintaining a print density of at least two, and a print to fail value of at least four. A print assembly including the dye-donor element and a receiver element is also described, as well as a method of printing using the dye-donor element.
摘要:
A diagnostic method for testing agitation of a photographic processing solution in a processing tank for a photographic processing apparatus of the type having a nozzle and adapted in use to impinge the photographic processing solution onto a photographic emulsion includes the steps of charging the processing tank with a solution containing a silver solvent, processing the photographic emulsion, and testing the processed photographic emulsion for patterns of silver remaining in the photographic emulsion, wherein such patterns are indicative of nozzle obstructions and thereby agitation levels present in the processing tank.

A thermal donor element having a dye layer on an extruded substrate, wherein the extruded substrate includes a polyester-containing material and a slip agent, but does not contain silica particles, is disclosed.
摘要:
Color photographic silver halide materials, especially color photographic papers, are processed effectively with reduced iron retention after bleaching with a biodegradable bleaching composition. Bleaching is accomplished using an iron chelate of a biodegradable chelating ligand in the presence of a polyphosphonic acid. This bleaching step is followed by fixing using a fixing composition that includes a fixing agent and a polycarboxylic acid.
摘要:
Color photographic silver halide elements, such as color films, can be rapidly fixed using a fixing composition containing a thiosulfate fixing agent, and certain 1,3-thiazolidine-2-thiones. Each of the components is present in specific amounts to effect rapid and efficient desilvering. The composition also includes predominantly ammonium cations (at least 50 mol %). Besides effective and rapid silver removal (less than 60 seconds), the fixing composition also minimizes residual dye stain from sensitizing dye aggregates within the photographic elements.

摘要:
Bleach compositions and methods that are improvements over those provided by Fyson, U.S. Pat. No. 4,294,914, are disclosed. A highly preferred bleach composition of this invention (a) has the ferric complex of methyliminodiacetic acid as a bleaching agent, and additionally comprises (b) at least 0.9 mole of acetic acid per liter, (c) from about 15 to about 35 grams per liter of potassium bromide; and (d) has a pH of from about 2.5 to about 4.0.This invention includes the discovery of a synergistic bleaching coaction of a bleach (i) comprising an alkyliminodiacetic acid such as methyliminodiacetic acid, and (ii) which has a pH of from about 3.5 to about 4.5 , and (iii) in which the amount of ferric iron is from about 2 to about 16 grams per liter. This coaction between iron levels and pH was previously unknown and was unexpected.Bleach formulations of this invention can be used in the processing of color photographic materials, such as film.
