Appts. producing three=dimensional pressure impacts in fluid - sequentially energises circular coils with current pulses to react with magnetic or magnetisable particles in sponge material

摘要

A vol. defined by an open porous sponge material (5) in which magnetic or magnetisable partic. are inlaid is surrounded by at least one magnetic drive stage consisting of a series of circular coils (2). This stage (1) is driven by a logic circuit so that the coils are sequentially powered by current pulses at a variable preselected pulse rate. A freq. modulated peristaltic movement is induced without a drop in pressure being necessarily incurred along the direction of movement of the fluid. Catalysts for chemical reactions can be inlaid in the pores of the magnetic-elastic sponge material. Alternatively, biological populations can be introduced for biological and/or biochemcial reactions. The sponge material can have micropores for use in filtration and separation. USE/ADVANTAGE - Peristaltic or rotary pump suitable for many purposes and transporting liq. or gases over long paths without pressive drop.
