Abstract
Abstract Streams of molten metal are converted into solidified metal filaments having point generatrix cross-sectional shapes by directing the stream into grooves formed into a moving chillblock surface. The grooves are shaped to form a mold of one surface of the point-generatrix shape and extend substantially in the direction of movement in the chill-block surface. The movement of the chill block is disposed to effect ejection of the solidified molten stream from the groove in the form of filaments by centrifugal force.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
In the method of melt spinning or casting metal filaments wherein a stream of molten metal is impinged on a moving chillblock surface and is ejected from said surface by centrifugal force in the form of a metal filament, the improvement of providing a groove or mound in the surface of said chill block that is substantially transverse to said molten metal stream so as to attenuate said stream into segmented filaments.
Claim 2
Dependent Claim
72 words
In the method of melt spinning or casting metal filaments wherein a stream of molten metal is impinged on a moving chillblock surface and is ejected from said surface by centrifugal force in the form of a metal filament, the improvement of providing a groove or mound in the surface of said chill block that is substantially transverse to said molten metal stream so as to attenuate said stream into segmented filaments.
Claim 3
Dependent Claim
105 words
In the method of melt spinning or casting metal filaments wherein a stream of molten metal is impinged on a moving chill block surface and is ejected from said surface by centrifugal forces in the form of a metal filament, the improvement of providing the chill block surface with a groove elongated in the direction of movement of said chill block surface said groove being provided with at least one substantially transverse groove that bisects and crosses said elongated groove and which is deeper than said elongated groove so as to cause the cast metal to attentuate into segments before being ejected from said surface.
Claim 4
Dependent Claim
105 words
In the method of melt spinning or casting metal filaments wherein a stream of molten metal is impinged on a moving chill block surface and is ejected from said surface by centrifugal forces in the form of a metal filament, the improvement of providing the chill block surface with a groove elongated in the direction of movement of said chill block surface said groove being provided with at least one substantially transverse groove that bisects and crosses said elongated groove and which is deeper than said elongated groove so as to cause the cast metal to attentuate into segments before being ejected from said surface.
Claim 5
Dependent Claim
27 words
The method of claim 2 wherein said substantially transverse groove is deeper than said elongated groove in an amount exceeding the thickness of the filament being cast.
Claim 6
Dependent Claim
92 words
In the method of melt spinning or casting metal filaments where a stream of molten metal is impinged on a moving chill block surface and is ejected from said surface by centrifugal forces in the form of a metal filament, the improvement of providing the chill block surface with a groove elongated in the direction of movement of said chill block surface said groove being provided with at least one substantially transverse mound higher than the bottom of said elongated groove in an amount exceeding the thickness of the filament being cast.
Claim 7
Dependent Claim
92 words
In the method of melt spinning or casting metal filaments where a stream of molten metal is impinged on a moving chill block surface and is ejected from said surface by centrifugal forces in the form of a metal filament, the improvement of providing the chill block surface with a groove elongated in the direction of movement of said chill block surface said groove being provided with at least one substantially transverse mound higher than the bottom of said elongated groove in an amount exceeding the thickness of the filament being cast.
Claim 8
Dependent Claim
82 words
In the method of melt spinning or casting metal filaments wherein a stream of molten metal is impinged on a moving chill-block surface and is ejected from said surface by centrifugal forces in the form of a metal filament the improvement of providing a chill-block surface consisting of the flat surface of an endless belt having grooves in the direction of movement with the solidification of the metal being affected at a rate ranging from approximately 50 to 1,000 feet per second.
