Abstract
Abstract Apparatus for applying a substance vaporizable by electron bombardment to a surface to form a coating thereon. The substance is vaporized in a vacuum by being bombarded with electrons. The vapor, thus formed, travels from where it is formed and is deflected onto such surface to coat the same.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
74 words
Apparatus for applying a substance vaporizable by electron bombardment onto a surface to form a surface coating, comprising in combination; a. means for generating a stream of electrons for bombarding a quantity of said substance to cause vaporization thereof, said generating means including an electrode system; b. said electrode system comprising a heated electrode which is disposed for mechanically deflecting the vapor thus formed from where said substance is electron bombarded onto such surface.
Claim 2
Dependent Claim
74 words
Apparatus for applying a substance vaporizable by electron bombardment onto a surface to form a surface coating, comprising in combination; a. means for generating a stream of electrons for bombarding a quantity of said substance to cause vaporization thereof, said generating means including an electrode system; b. said electrode system comprising a heated electrode which is disposed for mechanically deflecting the vapor thus formed from where said substance is electron bombarded onto such surface.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1 wherein said electrode system includes an anode disposed adjacent to a quantity of the substance to be vaporized, and said heated electrode is another electrode of said electrode system.
Claim 4
Dependent Claim
16 words
Apparatus according to claim 2 wherein said heated electrode is the cathode of said electrode system.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 1 wherein said electrode system includes a plurality of anodes one of which is the main anode, said main anode being formed by a quantity of the substance to be vaporized and wherein said vapor-deflecting means is another electrode of said electrode system.
Claim 6
Dependent Claim
16 words
Apparatus according to claim 1 wherein said vapor-deflecting means is an anode of said electrode system.
Claim 7
Dependent Claim
50 words
Apparatus according to claim 1 wherein the electron stream generator is arranged for directing the electron stream downwardly onto the substance to be vaporized and said heated electrode is disposed so as to cause vapor which travels upwardly from such substance to be deflected laterally with respect to said stream.
Claim 8
Dependent Claim
18 words
Apparatus according to claim 6 and incorporating a crucible for holding a quantity of liquid to be vaporized.
Claim 9
Dependent Claim

Claim 11
Dependent Claim
16 words
Apparatus according to claim 21 wherein said crucible is lined with a layer of refractory material.
Claim 12
Dependent Claim
17 words
Apparatus according to claim 7 wherein said crucible is provided with heat insulating on the outside thereof.
Claim 13
Dependent Claim
16 words
Apparatus according to claim 11 and incorporating means for heating the cathode of the electrode system.
Claim 14
Dependent Claim
19 words
Apparatus according to claim 12 wherein said cathode heating means is disposed between said cathode and a thermal screen.
Claim 15
Dependent Claim
