Abstract: A system in which mass quantities of liquids may be stored in a substantially frozen state, portions thawed for dispensing, and any undispensed thawed portions rechilled for further storage is disclosed. The system includes a tank with a substantially bell-shaped, or flared, interior, the flaring of the tank surface combining with force of gravity to detach frozen material for dispensing. Separate temperature control sections allow selected areas of the tank to be heated or cooled as necessary, moreover, and distinct reservoirs of heat-transfer liquid (such as glycol) may be used for heating versus cooling the tank.
Abstract: Apparatus and methods for spraying fluids are disclosed. Multiple distinctive airflows are used sequentially to create eddy currents at and near the outer canopies of vegetation. Such currents promote uniform chemical coverage of fruit and foliage throughout the vegetation. Nozzles adapted for selective use and adjustment independently and in multiple directions and planes also enhance coverage, particularly when fruit and foliage is especially dense or sparse or close to or remote from the ground.
