BLASTING APPAIIATU.U.S. Patent 6,000,995. Dec. 14, 1999H. Ruholl, assignor to HeinrichSchlick, Greven, GermanyA unit for the dosage of grained,pourable materials through anabrasive hose to a blast nozzle mix•ing chamber, a diffusor insert ar•ranged to extend along at least a

portion of the interior of the cham•ber tube opposite from the rearchamber wall, said abrasive hosebeing connected to said diffuser in•sert; a flow measuring device togenerate an output signal corre•sponding to material flow throughsaid down pipe; and an evaluationunit linked to the flow measuringdevice and the adjustable drive toregulate said adjustable drive in re•sponse to a comparison of said out•put signals to a preset nominalvalue to thereby provide a uniformand controllable flow rate of thematerial from the blast nozzle.

A method of continuously produc•ing a stream of ice particulatescomprising freezing water into athin, curved sheet of ice subject toself-fragmentation; harvesting atleast a portion of the self-frag•mented curved sheet of ice in theform of ice particulates directlyinto a stream of air of sufficientvelocity to fluidize the particu•lates, and the air at a tempera•ture above O·C; and continuouslyejecting the ice particulates undercontrolled velocity from a nozzle.
