Abstract
Abstract Thorough quenching of metal filaments extracted from a molten source using a quenching wheel as the quenching source can be achieved by prolonging the period of contact between the extracted molten metal and the quenching wheel until the desired quench temperature is reached. The period of contact may be prolonged by use of such devices as gas jets, moving belts or rotating wheels.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
In a method for the production of metal filament from a molten source using a rotating quench wheel as a quenching element upon which a molten filament is deposited, the improvement which comprises prolonging the period of contact between the deposited filament and the quenching wheel by external means acting on said deposited filament, said external means being applied over an elongated portion of the deposited filament thereby preventing separation of the filament from the quench wheel, which would result from the centrifugal force of rotation of said wheel acting on said filament, until the quench temperature of the filament is achieved.
Claim 2
Dependent Claim
102 words
In a method for the production of metal filament from a molten source using a rotating quench wheel as a quenching element upon which a molten filament is deposited, the improvement which comprises prolonging the period of contact between the deposited filament and the quenching wheel by external means acting on said deposited filament, said external means being applied over an elongated portion of the deposited filament thereby preventing separation of the filament from the quench wheel, which would result from the centrifugal force of rotation of said wheel acting on said filament, until the quench temperature of the filament is achieved.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein said external means to prolong the period of contact between the dePosited filament and the quench wheel is a co-directional rotating surface.
Claim 4
Dependent Claim
62 words
In an apparatus for the production of metal filaments by depositing a molten filament upon a rapidly rotating quenching wheel as a quenching element, the improvement which comprises applying an elongated external retaining means on said filament while it is being quenched on said rotating quenching wheel to extend the period of contact between the deposited metal filament and the quenching wheel.
Claim 5
Dependent Claim
62 words
In an apparatus for the production of metal filaments by depositing a molten filament upon a rapidly rotating quenching wheel as a quenching element, the improvement which comprises applying an elongated external retaining means on said filament while it is being quenched on said rotating quenching wheel to extend the period of contact between the deposited metal filament and the quenching wheel.
Claim 6
Dependent Claim
14 words
The apparatus of claim 3 in which the retaining means is a gaseous stream.
Claim 7
Dependent Claim
14 words
The apparatus of claim 3 in which the retaining means is a moving belt.
Claim 8
Dependent Claim
15 words
The apparatus of claim 3 wherein the retaining means contains therein an auxiliary chilling means.
Claim 9
Dependent Claim
90 words
In a method for the production of metal fialment from a molten source using a rotating quench wheel as a quenching element upon which a molten filament is deposited, the improvement which comprises prolonging the period of contact between the deposited filament and the quenching wheel by an auxiliary wheel spaced from the quench wheel thereby preventing separation of the filament from the quench wheel which would result from the centrifugal force of rotation of said wheel acting on said filament, until the quench temperature of the filament is achieved.
Claim 10
Dependent Claim
90 words
In a method for the production of metal fialment from a molten source using a rotating quench wheel as a quenching element upon which a molten filament is deposited, the improvement which comprises prolonging the period of contact between the deposited filament and the quenching wheel by an auxiliary wheel spaced from the quench wheel thereby preventing separation of the filament from the quench wheel which would result from the centrifugal force of rotation of said wheel acting on said filament, until the quench temperature of the filament is achieved.
Claim 11
Dependent Claim
66 words
In an apparatus for the production of metal filaments by depositing molten filament upon a rapidly rotating quenching wheel as a quenching element, the improvement which comprises utilizing an auxiliary retaining wheel, spaced from the quenching wheel, to retain said filament while it is being quenched on said rotating quenching wheel to extend the period of contact between the deposited metal filament and the quenching wheel.
Claim 12
Dependent Claim
66 words
In an apparatus for the production of metal filaments by depositing molten filament upon a rapidly rotating quenching wheel as a quenching element, the improvement which comprises utilizing an auxiliary retaining wheel, spaced from the quenching wheel, to retain said filament while it is being quenched on said rotating quenching wheel to extend the period of contact between the deposited metal filament and the quenching wheel.
