Title:
DEVICE FOR CONVEYING DAMP OR SALTS
Document Type and Number:
WIPO Patent Application WO1994020702
Kind Code:
A3
Abstract:
In a device for conveying damp or salts, e.g., to dry masonry, with at least one electrical conductor wound into a coil (100) and fitted in a housing, the winding diameter of the coil (100) diminishes spirally from one end to the other. Here the distance between the windings of a spiral or wedge-spiral coil (100) and the coil axis in the inward direction is 40 to 60 % smaller on each full revolution than the previous distance. On average, therefore, this gives: for the spiral radius measured at 90 DEG : R'1 = R1-R2/4; at 180 DEG : R''1 = R1-R2/2; at 270 DEG : R'''1 = R1-R2x3/4; at 360 DEG : R2 = R1/2.
