Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A sonic finishing apparatus, said apparatus comprising: an elastic vessel forming a finishing chamber for containing a combined continuous flow comprising an article to be finished in intimate contact with a finishing medium; an oscillator operatively coupled to said chamber to transmit vibrations thereto to elastically vibrate said chamber, and; means to adjust the pressure of said polishing medium on said article to be finished as said article and medium moves through said chamber in a continuous flow.
Claim 2
Dependent Claim
78 words
A sonic finishing apparatus, said apparatus comprising: an elastic vessel forming a finishing chamber for containing a combined continuous flow comprising an article to be finished in intimate contact with a finishing medium; an oscillator operatively coupled to said chamber to transmit vibrations thereto to elastically vibrate said chamber, and; means to adjust the pressure of said polishing medium on said article to be finished as said article and medium moves through said chamber in a continuous flow.
Claim 3
Dependent Claim
48 words
The apparatus of claim 1 comprising mounting means rotatably mounting said finishing chamber; and said pressure-adjusting means comprises driving means operatively connected to said chamber for rotating said chamber to apply centrifugal force to said polishing medium to thereby adjust the pressure of said medium on said article.
Claim 4
Dependent Claim
40 words
The apparatus of claim 1 wherein: said pressure-adjusting means comprises flow-restricting means to restrict the flow of said article and medium through said chamber to thereby create a column of said medium establishing a head of pressure in said chamber.
Claim 5
Independent Claim
89 words
A method of finishing industrial parts or articles, said method comprising the steps of: continuously moving a combined flow comprising at least an article along a path in intimate contact with finishing medium; applying to said combined flow of finishing medium and parts sonic energy in at least a portion of said path; adjusting the contact pressure of said finishing medium on the surface of said article to a value to yield the optimum finishing rate of said article by said medium as said articles and medium flow therethrough.
Claim 6
Independent Claim
89 words
A method of finishing industrial parts or articles, said method comprising the steps of: continuously moving a combined flow comprising at least an article along a path in intimate contact with finishing medium; applying to said combined flow of finishing medium and parts sonic energy in at least a portion of said path; adjusting the contact pressure of said finishing medium on the surface of said article to a value to yield the optimum finishing rate of said article by said medium as said articles and medium flow therethrough.
Claim 7
Dependent Claim
42 words
The method of claim 4 wherein the step of adjusting said contact pressure comprises the step of: subjecting at least a portion of said combined flow to centrifugal force to thereby increase the contact pressure between said finishing medium and said article.
Claim 8
Dependent Claim
40 words
The method of claim 4 wherein the step of adjusting said contact pressure comprises the step of adjusting the height of said flow of medium and article to an optimum height above the region of application of sonic energy thereto.
