摘要： A method is disclosed for washing silver halide photographic emulsions, including desalting and/or concentrating, based on depletion phase separation mechanism, wherein phase separation is effected by the addition of water-soluble non-interactive and non-adsorbing carboxyl polymers. The process involves the separation of the supernatant fluid, containing the undesirable water soluble salts and the added phase separating agents, from the washed and condensed silver halide phase for desalting and redispersion of the latter.

摘要： The present invention is a method for producing a silver halide emulsion. The precipitation of the emulsion is carried out away from the rotary agitator. The reactant solutions are introduced into the reactor very close to the tip of one or more ultrasonic horns that are placed away from the agitator. The ultrasonic horns are efficient sources for controlling micromixing, while the agitator controls the macromixing in the reactor.

摘要： A liquefying apparatus for melting and blending solid materials includes a hopper with a coiled heating element disposed therein which supports and melts the solid materials into liquid form. The hopper is segmented into a plurality of compartments and as the solid material melts the liquid is collected in the lower portion of the hopper. The collected liquid is continuously agitated to ensure that there are no concentration pockets. The lower section is also provided with a deaeration device to prevent entrained air from entering the liquid.

摘要： The present invention is a method for degassing an aqueous composition of chunked gelatin. Prior to melting the gelatin chunks, the gelatin is subjected to a pressure near the steam pressure corresponding to the temperature of the gelatin chunks. Application of this pressure degasses the gelatin chunks to that they can be sent directly to the melter and to the coating station.

摘要： A method and apparatus for converting gel-like substances from a gel state to a sol state in which the melting speed can be accurately controlled over a wide range and the apparatus can be easily cleaned. A grid-type heater constructed of rotatable parallel heating pipes is disposed at the bottom of a melting tank. Rotation of the pipes which simultaneously heating them imparts flowability to a heat transfer boundary formed on the side of the gel-like substance. The melting speed is controlled by controlling the speed of rotation of the pipes.
