摘要： The invention relates to a method and apparatus for storing heat in a heat-of-fusion storage medium, e.g. a salt hydrate, and the heat exchange and mixing in conjunction with the taking of heat from the storage medium. In a closed system including a vapor chamber (5) and a chamber for a solid/liquid phase, the storage medium (2, 4) is brought into direct contact with a substance, i.e., a heat transfer medium (3) having the capacity of taking up heat from the storage medium by being vaporized. The vapor travels to the vapor chamber (5), and when heat is removed from the vapor, the vapor is caused to condense and the condensate returns to the storage medium. The substance has insignificant solubility in the storage medium and a density which is higher, or equal to the density of the storage medium in its liquid phase. Suitable combinations of storage medium and substance include calcium chloride hexahydrate and trifluorotrichloroethane or Clauber's salt and octafluorocyclobutane.

摘要： A method is provided for controlling the amount of oxidizing bleaching agents in liquors used within the cellulose industry, as in the bleaching of sulphite, sulphate, mechanical, chemimechanical, semichemical or similar cellulose pulps, and in related industries, and particularly for controlling the addition of oxidizing bleaching agents to the system during the bleaching of cellulose pulp by mixing such liquor with at least one chemiluminescent reagent which reacts with the oxidizing bleaching agents in a manner to emit light. The amount of oxidizing bleaching agents in the liquor is then determined by comparison of the light intensity thus obtained with the light intensity for previously measured calibration values corresponding to known quantities of such oxidizing bleaching agents, and then from such determination controlling the addition of such oxidizing bleaching agents to the liquor.
