摘要： A thermoelectric Peltier heat transfer device is used to treat a fluid, such as a photographic processing solution to reduce or prevent biogrowth. The device include both hot and cold sides that are in direct fluid flow communication so that the same fluid is treated on both sides of the device. The treated fluid is subjected to flash pasteurization on the hot side of the device, and immediately and rapidly cooled on the cold side without loss of volume. Thus, the same fluid is treated on both sides of the heat transfer device in a closed system before being returned to desired chemical, photographic or other processes.

摘要： A color developing composition is stable in the presence of calcium ion because of the presence of two specific types of polyphosphonic acid sequestering agents. The composition also comprises a color developing agent in free base form and an antioxidant for the color developing agent. The mixture of sequestering agents includes a polyaminopolyphosphonic acid and either a hydroxyalkylidenediphosphonic acid or morpholinomethanediphosphonic acid. The composition can be used to provide images in various color photographic silver halide materials.

摘要： A method of reducing uneven use of the total number of printing elements on a print head in a printer, when selectively using the printing elements to make different size color image prints on respective similar size receiver mediums, comprises: selectively using the total number of printing elements to make color image prints substantially the same size as the receiver mediums; and selectively using a particular number of printing elements less than the total number of printing elements to make similar size color image prints smaller than the receiver mediums, but alternating which ones of the total number of printing elements can be selectively used to make each print so that the placement of each print on a receiver medium is alternated, whereby, since those printing elements that can be selectively used to make each print smaller than a receiver medium are alternated, uneven use of the printing elements is reduced.
