Abstract
Abstract A device for coating a wire continuously from the gas phase, comprising a tubular reaction chamber provided with at least one inlet and outlet for the gas or gas mixture providing the coating and with seals at both ends through which the wire is passed, which seals comprise a wire filling of metal wire serving as an electrical contact with the wire to be coated, and a chamber arranged in series with the reaction chamber in which a gas such as a rare gas, nitrogen or hydrogen is passed, which chamber has two apertures of small diameter through which the wire to be coated can be passed with some clearance.

Claim 3
Dependent Claim
52 words
A device as claimed in claim 1, wherein the ratio of the diameters of the apertures through which the wire is passed is such that the gas introduced into the chambers leaves these chambers mainly through said aperture through which the wire is passed into the reaction chamber or leaves said chamber.
Claim 4
Dependent Claim
18 words
A device as claimed in claim 1, wherein the wire filling of metal wire consists of tungsten wire.
