    Abstract: A process is disclosed for the production of alumina by the Bayer process, including a precipitation process having an agglomeration stage and a growth stage in which the precipitation slurry is passed through a multiplicity of growth tanks. In the agglomeration stage, the precipitation slurry is maintained at a temperature of about 75.degree. C. to 85.degree. C. In the growth stage, the agglomeration slurry is cooled by about 1.degree. C. to 3.degree. C. in each growth tank of the multiplicity of growth tanks as compared to an adjacent previous growth tank. The temperature of the precipitation slurry leaving the final precipitator is preferably about 55.degree. C.

    Abstract: An apparatus for heating or cooling solid suspension slurry. The apparatus comprises a vessel (1) for containing the slurry and a draft means contained within a draft section of a draft tube (2) to circulate and maintain the suspension. Extending substantially the length of cylindrical section (26) of the draft tube below the draft means are plate heat exchangers (7, 21, 23, 25, 27, 29) connected in series. The plate heat exchangers may be recessed into the wall of the draft tube so as not to increase the pressure drop through the draft tube or may be arranged in pairs along the axis of the draft tube so that the proportion of the cross-sectional area of the draft tube occupied by the heat exchangers is minimized.

    Abstract: A lightweight, foldable cover adapted for attachment to a portable electric generator permits the generator to be operated while covered and shielded from weather. The cover includes rigid or semi-rigid sides hingeably joined and held in position with flexible straps. The cover allows unimpeded exhaust and airflow underneath the cover, and unimpeded access to controls and outlets. The flexible straps attach to the cover and the frame of the generator. The straps are adjustable to accommodate different generator frame sizes, and include quick release devices to allow rapid attachment to, or detachment from the generator frame for refueling or storage. When removed the cover folds nearly flat for storage.
