Abstract
Abstract Improvement in apparatus for making metal filament by depositing a stream of molten metal onto the inner surface of an annular chill roll as it is being rotated includes provision of a rotatably mounted annular chill roll having an inner surface substantially parallel to its axis of rotation, and means for stripping the metal filament from the inner surface of the chill roll and for guiding the stripped metal filament away from the chill roll.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A continuous process of forming filament of amorphous metal from a molten metal alloy capable of forming an amorphous structure comprising: (a) depositing a stream of the molten metal alloy onto the inner surface of a rotating annular chill roll having an inner surface parallel to its axis of rotation, (b) quenching the molten metal in contact with said surface at a rapid rate to effect solidification into a continuous solid amorphous metal filament, (c) stripping the amorphous metal filament from said surface, and (d) continuously guiding the stripped filament away from said surface.
Claim 2
Dependent Claim
94 words
A continuous process of forming filament of amorphous metal from a molten metal alloy capable of forming an amorphous structure comprising: (a) depositing a stream of the molten metal alloy onto the inner surface of a rotating annular chill roll having an inner surface parallel to its axis of rotation, (b) quenching the molten metal in contact with said surface at a rapid rate to effect solidification into a continuous solid amorphous metal filament, (c) stripping the amorphous metal filament from said surface, and (d) continuously guiding the stripped filament away from said surface.
Claim 3
Dependent Claim
40 words
The process of claim 1 wherein the continuous amorphous metal filament is stripped from the chill roll by directing a jet of fluid against the inner surface of the chill roll so as to lift the filament from that surface.
Claim 4
Dependent Claim
15 words
The process of claim 2 wherein the jet of fluid is a jet of air.
Claim 5
Dependent Claim
22 words
The process of claim 1 wherein the filament is stripped from the chill roll by means of suction applied by an aspirator.
Claim 6
Dependent Claim
20 words
The process of claim 1 wherein the filament is stripped from the chill roll by means of a rotating brush.
Claim 7
Dependent Claim
20 words
The process of claim 1 wherein the filament is stripped from the chill roll by means of a scraper blade.
Claim 8
Dependent Claim
9 words
The process of claim 1 conducted under reduced pressure.
