Abstract: A method of and apparatus for the electrostatic coating of poorly or non-conductive materials such as pellets seeds and powders, in which the product material is set in motion, preferably turbulent or agitating motion relative to at least one electrostatic coating material spraying device which is directed toward the moving product and has applied thereto a high potential difference whereby the coating material is given an electrostatic charge and an electrostatic charge of opposite polarity is induced on the product causing electrostatic attraction between the coating material and the product. The invention is applicable both to continous and batch production of coated material and preferably involves moving the product past the or each spraying device in a plurality of spraying passes. Charged atomised liquid and diffused powder may be sprayed onto the product either in sequence or at the same time.

Abstract: PCT No. PCT/DE86/00005 Sec. 371 Date Sep. 9, 1986 Sec. 102(e) Date Sep. 9, 1986 PCT Filed Jan. 10, 1986 PCT Pub. No. WO86/04149 PCT Pub. Date Jul. 17, 1986.Method for measuring the direction and force of gaseous or liquid flows in which two dynamic pressures are measured which are built up in two measuring chambers under the influence of the flow at a certain free-stream angle or a plurality of dynamic pressures are measured which build up in a plurality of measuring chambers under the influence of the flow at a certain free-stream angle, and wherein from the difference or the quotient of measured dynamic pressures or from absolutely or vectorially added measured values the direction and/or the force of the flow is determined through mathematic processing. The measuring chamber openings are rectangular-shaped or slot-shaped, the center lines of a pair of measuring chamber openings are positioned in a plane, and the arrangement of the measuring chamber openings relative to each other is fixed. Furthermore a probe for carrying out this method is disclosed.

Abstract: In the electrostatic application of a coating material on to a product to be coated, the product leaves a supply hopper (1) over a tube enlargement (5A) and falls freely in a chamber (2) in the form of a tubular curtain. The tubular curtain falls around a central, elongate, vertical corona discharge electrode (6) so that a high voltage electrostatic charge of one sign is applied to the falling curtain of the product. Coating material is sprayed on to the product by atomizers (A1 to A6) in the chamber (2). A high voltage electrostatic charge of opposite sign is applied to the coating material by way of the atomizers (A1 to A6).

Abstract: A method of and apparatus for the electrostatic application of a coating material on a product of either electrically conducting or non-conducting material. The product is caused to descend from a hopper (10) in free fall in the form of spaced curtains (28, 30) across two streams (40, 42) of electrostatically charged coating material directed laterally of the curtains from opposite sides thereof. The rate of flow and spacing of the curtains (28, 30) is adjustable (32, 14, 16, 18, 20, 22, 26) as required depending upon the nature of the product and the properties of the coating material. Charges of opposite polarity are applied respectively to the two streams with the result that an electrostatic charge opposite to that of a stream is imparted to that side of each of the two curtains towards which the stream is directed causing attraction between the coating material and the product. The uniformity of the applied coating is much improved as compared with conventional techniques.
