Abstract
For producing controlled precipitation in fluid flowing through a pipe, a coil of electric wire, of flat, generally rectangular spiral shape, is sandwiched between flexible cover sheets. The resulting assembly is applied to the outer circumference of the pipe, with the lengthwise dimension of the coil extending perpendicularly to the flow inside the pipe. A time-varying electric current is applied to the coil to produce a corresponding magnetic field. This, in turn, causes induction which produces the controlled precipitation.
