## Abstract

Method and Apparatus for high intensity infrared burn-off of contaminants on articles moving continuously through an in-line production process.

## Claims

### Claim 1

A method of rapid incineration of contaminants on articles in a continuous moving environment without removing the articles from the conveyance means, comprising the steps of:
A) passing the articles in situ on the conveyance means past a high intensity energy source;
B) elevating the temperature of the contaminants on the article to the incineration point;
C) supplying energy to the high intensity energy source in proportion to the speed of the moving articles whereby the time of the articles within the high intensity energy source equals the time to the incineration point and,
D) only energizing the high intensity energy source during intervals when the article is within the high intensity energy source.

### Claim 2 (depends on 1)

The method of claim 1 wherein the energy source is in a range of 100 to 500 watts/square inch.

### Claim 3 (depends on 1)

Method of claim 1 wherein the temperature of the contaminant is elevated to the range of 800° F. to 2000° F.

### Claim 4 (depends on 1)

Method of claim 1 wherein the article is within the energy source only 1¾ minutes.

### Claim 5 (depends on 1, 3)

The additional step to claim 1 of heating the article to a temperature equal to that of the method of claim 3.

### Claim 6 (depends on 1)

The method of claim 1 including the further step of physically removing any contaminant residual.

### Claim 7 (depends on 6)

The method of claim 6 wherein the physical removal step includes brushing.

### Claim 8 (depends on 6)

The method of claim 6 wherein the physical removal step includes spraying a fluid.

### Claim 9 (depends on 9)

The method of claim 9 including the further step of cleaning the article with an ultra-sonic cleaning bath.
