Abstract
Abstract A method and an apparatus for reducing of and diverting radiation from all kinds of radiation emitting surfaces like viewing screens, TV screens, chassis, apparatus boxes etc. whereby an electrically conducting current diverting means (11), for instance a coil of stainless steel, is applied in direct contact with the radiation emitting surface (9) and is connected to earth (12), and whereby a fluid layer containing film or foil or a mass is applied directly to the radiation emitting surface (9) and the diverting means (11), said fluid layer or mass comprising a salt of electrolytic type, and in which the mass is of the type which forms a surface skin or becomes dried right through when being exposed to air, and said layer or mass being electrically conducting even in such dried state, and whereby the apparatus is ready for being used when said mass has formed a skin or has become dried. The current diverting means can be applied after the application of the electrolytic layer or mass. The fluid layer or covering mass preferably is a salt of an acid and an alkali metal or calcium, for instance sodium or potassium lauryl ether sulphate or calcium lauryl ether sulphate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
99 words
Method of reducing and diverting radiation from any kind of radiation emitting surfaces like viewing screens, TV screens, chassis and apparatus boxes etc, characterized in that a layer of fluid (8) or a mass comprising or consisting of a salt of electrolytic type is applied in direct contact with the radiation emitting surface (1; 9), and in that an electrically conducting current diverting means (11) is applied to said surface (1; 9) and in intimate contact with said layer of fluid (8) or mass, before or after the said layer or mass is applied to the radiation emitting surface.
Claim 2
Dependent Claim
99 words
Method of reducing and diverting radiation from any kind of radiation emitting surfaces like viewing screens, TV screens, chassis and apparatus boxes etc, characterized in that a layer of fluid (8) or a mass comprising or consisting of a salt of electrolytic type is applied in direct contact with the radiation emitting surface (1; 9), and in that an electrically conducting current diverting means (11) is applied to said surface (1; 9) and in intimate contact with said layer of fluid (8) or mass, before or after the said layer or mass is applied to the radiation emitting surface.
Claim 3
Dependent Claim
109 words
Method according to claim 1, characterized in that the layer of fluid (8) is an electrically conducing layer facing the radiation emitting surface and provided on a clear, transparent carrier film or foil (7), which conducting layer is impregnated in the carrier film or foil or is bound to said film or foil by means of an easily penetratable second foil, a layer of gelatine or a similar material, and which is penetrated when the foil with the fluid layer is applied to the radiation emitting surface, so that the electrically conducting fluid comes in direct and full contact with radiation emitting surface and with the current diverting means.
Claim 4
Dependent Claim
63 words
Method according to claim 1, characterized in that the mass comprising or consisting of an electrolytic salt is of the type which, when exposed to air, forms a surface skin is dried right through, and which even in dried state is electrically conducting, and which reaches the intended effect as soon as the mass has formed the surface skin or has become dried.
Claim 5
Dependent Claim
72 words
Method according to claims 1, 2 or 3, characterized in that carriers, for instance carrier buttons (13) are attached to the surface of the radiation emitting apparatus (9), especially at or close to the corners of said surface, and in that an electric diverting means having an earth connecting means (12), preferably in the form of a coil (11), is put over said buttons (13), whereupon the electrolytic covering mass is applied.
Claim 6
Dependent Claim
49 words
Method according to any of claims 1-4, characterized in that the fluid layer or the covering mass is a salt of an acid, for instance a sulphate of an alkali metal like sodium lauryl ether sulphate or potassium lauryl ether sulphate, or of calcium, like calcium lauryl ether sulphate.
Claim 7
Dependent Claim
33 words
Method according to any of claims 1-5, characterized in that an adhesive substance is admixed in the fluid layer or the covering mass, for instance a wax in finely dispersed or melted form.
Claim 8
Dependent Claim
104 words
Apparatus for executing the method according to any of claims 1-6 for diverting of electrostatic radiation from radiation emitting surfaces like viewing screens, apparatus chassis etc. characterized in that the apparatus comprises an electric diverting means (11) having an earth connecting means (12) adapted to be attached in intimate conducting contact with the radiation emitting surface (1; 9) and adapted to be earth connected, and a fluid layer (8) or a covering mass comprising or consisting of a salt of electrolytic type which is applied over and in intimate contact with the electric diverting means (11) and with the radiation emitting surface (1; 9).
Claim 9
Dependent Claim
97 words
Apparatus according to claim 7, characterized in that the fluid layer (8) is an electrically conducting layer facing the radiation emitting surface and impregnated in a clear, transparent carrier film or foil (7), or bound to the carrier film or foil (7) by means of an easily penetratable second foil, a gelatine layer or a similar material, which is penetrated when the foil with the fluid layer is applied to the radiation emitting surface, so that the electrically conducting fluid comes in direct and full contact with the radiation emitting surface and with the current diverting means.
Claim 10
Dependent Claim
46 words
Apparatus according to claim 7, characterized in that the mass comprises or contains an electrolytic salt of a type which is adapted to form a surface skin or to become dried in contact with the air, and which is electrically conducting even after having become dried.
Claim 11
Dependent Claim
