Abstract
Abstract An ultrasonic vibrator of the type used to atomize liquid is used for applying liquid finish to a moving threadline. The liquid is supplied to a through passage in the tip of the horn of the vibrator in which it is atomized and applied to the threadline which is moving through the passage in the tip of the horn.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
70 words
A method for applying a liquid to a threadline comprising: supplying liquid in a metered stream to an atomizing surface of a passage through the tip of a horn of an ultrasonic vibrator; vibrating said horn to atomize said liquid and produce a mist; and moving said threadline in a path through said passage in such close proximity to said atomizing surface that said mist is propelled onto said threadline.
Claim 2
Independent Claim
70 words
A method for applying a liquid to a threadline comprising: supplying liquid in a metered stream to an atomizing surface of a passage through the tip of a horn of an ultrasonic vibrator; vibrating said horn to atomize said liquid and produce a mist; and moving said threadline in a path through said passage in such close proximity to said atomizing surface that said mist is propelled onto said threadline.
Claim 3
Dependent Claim
30 words
The method of claim 1, said liquid being supplied to said atomizing surface in separate metered streams which are joined at a location just prior to reaching said atomizing surface.
Claim 4
Dependent Claim
17 words
The method of claim 1, said liquid being formed of separate metered streams of oil and water.
Claim 5
Dependent Claim
10 words
The method of claim 3, said oil being water insoluble.
Claim 6
Dependent Claim
9 words
The method of claim 3, said oil being emulsifiable.

Dependent Claim
17 words
The method of claim 1, said liquid being supplied to said atomizing surface in separate metered streams.
Claim 9
Independent Claim
57 words
A method of applying a liquid to a threadline comprising: supplying the liquid in a continuous metered stream to a through passage in the tip of an ultrasonic vibrator; atomizing the liquid in said through passage by means of said vibrator; and vibrating the threadline by means of said vibrator while forwarding it through said through passage.
Claim 10
Independent Claim
57 words
A method of applying a liquid to a threadline comprising: supplying the liquid in a continuous metered stream to a through passage in the tip of an ultrasonic vibrator; atomizing the liquid in said through passage by means of said vibrator; and vibrating the threadline by means of said vibrator while forwarding it through said through passage.
Claim 11
Dependent Claim
17 words
The method of claim 8, said liquid being supplied to said atomizing surface in separate metered streams.
Claim 12
Dependent Claim
30 words
The method of claim 8, said liquid being supplied to said atomizing surface in separate metered streams which are joined at a location just prior to reaching said atomizing surface.
Claim 13
Dependent Claim
19 words
The method as defined in claim 8, said liquid being formed of separate metered streams of water and oil.
Claim 14
Dependent Claim
10 words
The method of claim 11, said oil being water insoluble.
Claim 15
Dependent Claim
9 words
The method of claim 11, said oil being emulsifiable.
Claim 16
Independent Claim
58 words
A method of applying a liquid to a threadline comprising: supplying the liquid in a continuous metered stream to a through passage in the tip of an ultrasonic vibrator; atomizing the liquid to produce a mist in said through passage by means of said vibrator; and forwarding the threadline through said through passage in contact with said tip.
Claim 17
Independent Claim
58 words
A method of applying a liquid to a threadline comprising: supplying the liquid in a continuous metered stream to a through passage in the tip of an ultrasonic vibrator; atomizing the liquid to produce a mist in said through passage by means of said vibrator; and forwarding the threadline through said through passage in contact with said tip.
Claim 18
Dependent Claim
17 words
The method of claim 14, said liquid being supplied to said atomizing surface in separate metered streams.
Claim 19
Dependent Claim
30 words
The method of claim 14, said liquid being supplied to said atomizing surface in separate metered streams which are joined at a location just prior to reaching said atomizing surface.
Claim 20
Dependent Claim
19 words
The method as defined in claim 14, said liquid being formed of separate metered streams of water and oil.
Claim 21
Dependent Claim
10 words
The method of claim 17, said oil being water insoluble.
