Abstract: The CRT screen attachment has a grey glass screen with an anti-reflective coating applied to its front surface and a metallic absorption coating applied to its rear surface. The earthed anti-static absorption coating is made of chrome or a chrome/nickel alloy, e.g. a chrome/nickel silicide, with a thickness which reduces the light transmission by about one third. Pref. the absorption coating has a surface resistance of between 0.5 and 20 miloOhm, e.g. 1 kilOhm.

Abstract: When metal conductors are stored, especially in humid environments, their solderability decreases. The rate at which solderability decreases can be reduced by treating the conductor with a suitable surface active agent, particularly one which has an HLB (hydrophile-lipophile balance) number of less than 10, preferably less than 5. The surface active agent can be applied to the conductor with a suitable liquid carrier, eg. as a solution in a mineral oil or a halogenated hydrocarbon. If desired, a polymeric insulating jacket can be melt-extruded or wrapped over the treated conductor.
