Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
55 words
In a gas laser including means for supplying a lasing gas and means for producing an electrical discharge through said gas, the improvement comprising spiral fin assembly means for directing said gas in a spiral path, said spiral fin assembly means including at least one aperture in each fin through which said electrical discharge passes.
Claim 2
Dependent Claim
55 words
In a gas laser including means for supplying a lasing gas and means for producing an electrical discharge through said gas, the improvement comprising spiral fin assembly means for directing said gas in a spiral path, said spiral fin assembly means including at least one aperture in each fin through which said electrical discharge passes.
Claim 3
Dependent Claim
41 words
The laser recited in claim 1 wherein, said spiral fin assembly includes a central support member, and at least one fin structure attached to and supported by said central support member to define a spiral path around said central support member.
Claim 4
Dependent Claim
22 words
The laser recited in claim 2, wherein, said central support member is hollow such that a cooling fluid can be passed therethrough.
Claim 5
Dependent Claim
37 words
The laser recited in claim 2 wherein, said central support member is solid, and an outer housing substantially concentric to and spaced from said central support member and connected to the outer ends of said fin structure.
Claim 6
Dependent Claim
24 words
The laser recited in claim 1 wherein, said spiral fin assembly includes a plurality of individual segments which are electrically isolated from each other.
Claim 7
Dependent Claim
24 words
The laser recited in claim 1 including, magnetic means disposed adjacent to said spiral fin assembly to control the path of said electrical discharge.
Claim 8
Dependent Claim
19 words
The laser recited in claim 1 including, external casing means surrounding said spiral fin assembly to confine said gas.
Claim 9
Dependent Claim
58 words
In a gas laser including means for supplying a lasing gas and means for producing an electrical discharge through said gas, the improvement comprising fin assembly means for directing said gas in a predetermined path, said fin assembly means including at least one aperture in each fin of said fin assembly means through which said electrical discharge passes.
Claim 10
Dependent Claim
58 words
In a gas laser including means for supplying a lasing gas and means for producing an electrical discharge through said gas, the improvement comprising fin assembly means for directing said gas in a predetermined path, said fin assembly means including at least one aperture in each fin of said fin assembly means through which said electrical discharge passes.
