Abstract: An economical, industrial and ecologically-sound process for producing high test hypochlorite and a calcium chloride aqueous solution comprising the steps of (a) preparing milk of lime, (b) chlorinating the milk of lime to crystallize calcium hypochlorite dihydrate in the presence of the prismatic calcium hypochlorite dihydrate seed crystals having a specific habit to prepare a slurry of coarse calcium hypochlorite dihydrate crystals, (c) separating the slurry into a wet cake of calcium hypochlorite dihydrate crystals and a mother liquor containing calcium hypochlorite and calcium chloride, (d) drying the wet cake to provide high test hypochlorite, and (e) adding hydrochloric acid to the mother liquor or bringing the mother liquor into contact with an oxide of at least one of Mn, Fe, Co, Ni, Cu, and Pd to decompose the calcium hypochlorite to obtain a calcium chloride aqueous solution.

Abstract: In a print control method for a host computer and a printer, a plurality of process steps for print data are stored in both the host computer and the printer. The host computer determines a process step which produces a minimum amount of transfer data with respect to an attribute of an input data. The host computer executes process steps starting from an initial process step to the determined process step to produce incompletely-processed data which is transferred to the printer. The printer executes the remaining process steps to produce completely-processed data.
