Abstract: A photographic film cartridge assembly has front and rear opposed walls between which photographic film is movable to align image areas with an exposure window in the front wall. A film support surface is enterable into the cartridge assembly through the exposure window. An opening in the rear wall is aligned with the exposure window, and a pressure plate is retained on the rear wall for movement toward and away from the front wall. Baffle means on the pressure plate and the rear wall form a tortuous light path to prevent light entering the cartridge assembly through the opening from reaching the film.

Abstract: Apparatus is provided for handling heat-softenable batch material prior to melting it. The batch components are mixed together and then mixed with liquid and formed into balls or pellets of substantially uniform size and shape. The pellets are then collected into a heat-exchange chamber through which hot gases are passed from a melting unit in which the pellets are to be heated to a heat-softened state. The pellets thereby are preheated prior to entering the melting unit to save considerably on energy requirements. A physical characteristic and specifically the depth of a portion of the batch being formed into the pellets is sensed, the depth being related to moisture content. The ratio of the batch material and liquid is accordingly regulated to achieve uniformity in pellet size, which is influenced by the moisture content. Size uniformity is important in maintaining relatively free flow of the hot gases through the pellets in the heat-exchange chamber.

Abstract: Process for producing diammonium phosphate (DAP) fertilizer from phosphoric and sulfuric acids, anhydrous ammonia and water in a specially designed reactor operated at high pressures to granulate diammonium phosphate at low recycle ratios and with either no, or relatively small, fossil fuel requirement drying per ton of product. By operating at elevated pressures, it is possible to force ammonia into a high temperature (250.degree. to 300.degree. F.) melt without exceeding the recovery capacity of the acid fed to the scrubber. The high pressure slurry from the reactor is forced into the bed of materials in a rotary granulator. Previously operated reactors employed pressures ranging from 0 to 10 psig pressures. This reactor operates at 40 to 80 psig. The process substantially increases production in existing DAP granulation plants and has helped reduce grade deficiencies.

Abstract: A tube is inserted in a bore in a tube sheet, the tube having an outside diameter slightly smaller than the bore. Hydraulic pressure is applied to the tube internally to expand it radially throughout a pressure zone that extends at least up to one end of the bore. The pressure is confined between two axially spaced seals that encircle a mandrel and are engagable with the inner surface of the tube. The mandrel and seals are then shifted to relocate the pressure zone so that it does not reach the end, and increased pressure is applied to produce a firmer contact between the outside of the tube and the bore. Any crevices between the tube and the tube sheet in which corrosion would be likely to occur are thus eliminated. The invention is particularly suitable for use in connection with the heat exchangers of nuclear plants.
