Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A method for manufacturing heat emitting plates comprising the steps of: coating both surfaces of a metal plate with a dielectric coating; heating the coated plate to a temperature between 300° C. and 400° C.; and spraying molten conductive metal over at least one of the coated surfaces in a manner such that the depth of the conductive metal sprayed onto the coated surface is uniform along any transverse section of the plate; wherein the step of spraying includes moving the plate relative to a spraying means at a relatively non-uniform speed so as to vary the thickness of the metal sprayed onto the plate along different portions of the length of the plate.
Claim 2
Independent Claim
114 words
A method for manufacturing heat emitting plates comprising the steps of: coating both surfaces of a metal plate with a dielectric coating; heating the coated plate to a temperature between 300° C. and 400° C.; and spraying molten conductive metal over at least one of the coated surfaces in a manner such that the depth of the conductive metal sprayed onto the coated surface is uniform along any transverse section of the plate; wherein the step of spraying includes moving the plate relative to a spraying means at a relatively non-uniform speed so as to vary the thickness of the metal sprayed onto the plate along different portions of the length of the plate.
Claim 3
Dependent Claim
46 words
The method according to claim 1, further comprising the steps of applying a corrosion-protective material pattern onto the sprayed metal and removing the sprayed metal from the plate with a corrosive agent at locations other than those protected from the agent by the corrosion-protective material pattern.
Claim 4
Dependent Claim
33 words
The method according to claim 2, wherein the corrosion-protective material pattern is painted onto the plate on the sprayed metal and has a prescribed length and a width which varies throughout that length.
Claim 5
Dependent Claim
23 words
The method according to claim 2, wherein the corrosion protective material pattern has a prescribed length and a uniform width throughout that length.
Claim 6
Dependent Claim
30 words
The method according to claim 2, wherein said corrosion-protective material pattern is painted onto said sprayed metal and takes the form of at least two mutually insulated and spaced patterns.
Claim 7
Dependent Claim
14 words
The method according to claim 5, wherein said mutually insulated patterns have different lengths.
Claim 8
Dependent Claim
14 words
The method according to claim 5, wherein said mutually insulated patterns have different widths.
Claim 9
Dependent Claim
24 words
The method according to claim 2, wherein said pattern of corrosion-protective material includes a plurality of areas which are separated lengthwise along said plate.
Claim 10
Dependent Claim
13 words
The method according to claim 8, wherein said pattern has a zig-zag configuration.
Claim 11
Dependent Claim
17 words
The method according to claim 8, wherein said pattern has at least two uniformly spaced zig-zag sections.
Claim 12
Dependent Claim
23 words
The method according to claim 2, wherein said pattern is in the form of a zig-zag line of varying widths throughout its length.
Claim 13
Dependent Claim
18 words
The method according to claim 11, wherein the width of said zig-zag line gradually increases with its length.
Claim 14
Dependent Claim
19 words
The method according to claim 2, wherein the width of said pattern varies along the length of said plate.
