Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
Method of generating a substantially sharply collimated beam of condensed matter which comprises feeding a stream comprising condensed matter and residual gas matter produced by expanding a gas out of a nozzle; mechanically deflecting said stream from its feed direction; exerting a centrifugal force on said stream by said deflection; resuming the flow of said stream after said deflection in substantially the same direction as the direction of the feeding of said stream; separating said stream into a condensed matter component and a residual gas matter component; and feeding said condensed matter component into a vacuum, wherein said mechanical deflection is accomplished by passing said stream through a changing diameter annulus with smooth curved walls sufficient to exert said centrifugal force on said stream.
Claim 2
Dependent Claim
124 words
Method of generating a substantially sharply collimated beam of condensed matter which comprises feeding a stream comprising condensed matter and residual gas matter produced by expanding a gas out of a nozzle; mechanically deflecting said stream from its feed direction; exerting a centrifugal force on said stream by said deflection; resuming the flow of said stream after said deflection in substantially the same direction as the direction of the feeding of said stream; separating said stream into a condensed matter component and a residual gas matter component; and feeding said condensed matter component into a vacuum, wherein said mechanical deflection is accomplished by passing said stream through a changing diameter annulus with smooth curved walls sufficient to exert said centrifugal force on said stream.
Claim 3
Dependent Claim
17 words
A method as claimed in claim 1, wherein said annular deflection is through a decreasing diameter annulus.
Claim 4
Dependent Claim
17 words
A method as claimed in claim 1, wherein said annular deflection is through an increasing diameter annulus.
Claim 5
Dependent Claim
17 words
Method claimed in claim 1 wherein said deflection is through an angle of up to about 270*.
Claim 6
Dependent Claim
11 words
Method claimed in claim 4 wherein said angle is about 90*.
Claim 7
Dependent Claim
14 words
Method claimed in claim 1 including subjecting said stream to a multiplicity of deflections.
