Title:
DEVICE FOR CLEANING A SURFACE IN ORDER TO REMOVE STICKY SUBSTANCES
Document Type and Number:
WIPO Patent Application WO/1989/010213
Kind Code:
A1
Abstract:
A device for cleaning a surface of sticky substances comprises a multilayer electromagnetic coil (1), a pulsed-current source (3) and a paramagnetic plate (4) placed between the surface (5) to be cleaned and the electromagnetic coil (1). The number n of the layers (5) in the coil (1) varies from two to five, each layer (8) consisting of a spiral current-conducting bus (7) of a rectangular cross-section. The layers (8) are located in parallel planes and are connected correspondingly. For two-, three-, four- and five-layer electromagnetic coils (1) there are predetermined relationships between the number W of loops (9) in each layer (8) and the optimal number W1 of the loops (9) and between the height h of the current-conducting bus (7) and an equivalent depth DELTA of penetration of the magnetic field into the metal of the electromagnetic coil (1).
