Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
THE METHOD OF COATING ARTICLES WITH A METAL, WICH COMPRISES METLTING A METAL TO FORM A BODY OF MELT, CONTINUOUSLY CIRCULATING THE MELT OVER AN OPEN CHANNEL, GENERATING COMPRESSIONAL OSCILLATIONS WITHIN THE MELT CIRCULATING IN THE OPEN CHANNEL OF SUFFICIENT ENERGY TO CAUSE SEVERE CAVITATION WITHIN A LOCALIZED REGION OF THE MELT TO AN EXTEND THAT A FREE SURFACE OF THE MELT IS RUPTURED AND GLOBULES OF MOLTEN METAL BREAK OFF FROM THE RUPTURED SURFACE AND ARE EJECTED INTO THE SPACE ABOVE, AND PLACING AN ARTICLE TO BE COATED IN THE PATHS OF THE EJECTED GLOBULES SO THAT SAID GLOBULES IMPINGE UPON A SURFACE OF THE ARTICLE.
Claim 2
Independent Claim

Claim 3
Dependent Claim
53 words
THE METHOD ACCORDING TO CLAIM 1 WHEREIN THE ARTICLE IS PRINTED CIRCUIT BOARD HAVING METAL CIRCUIT PATHS FIXED TO THE SURFACE THEREOF, THE METAL IS A SOLDER CAPABLE OF WETTING SAID METAL CIRCUIT PATHS, AND THE BODY OF MELT IS CAUSED TO CIRCULATE OVER THE OPEN CHANNEL IN A STREAM OF PREDETERMINED DEPTH.
Claim 4
Dependent Claim
87 words
APPARATUS FOR METAL-COATING ARTICLES, WHICH COMPRISES: MEANS FOR CONTAINING A BODY OF MOLTEN METAL; MEANS FOR CIRCULATING THE MOLTEN METAL OVER AN OPEN CHANNEL; MEANS FOR GENERATING HIGH FREQUENCY, COMPRESSIONAL OSCILLATIONS WITHIN THE MOLTEN METAL IN THE OPEN CHANNEL, SAID OSCILLATIONS BEING OF SUFFICIENT INTENSITY AND FREQUENCY AS TO CAUSE SEVERE CAVITATION, RUPTURE OF A FREE SURFACE OF THE MOLTEN METAL AND EJECTION OF GLOBULES OF THE METAL INTO THE SPACE ABOVE; AND MEANS FOR POSITION AN ARTICLE TO BE METAL CONTACT WITH SAID EJECTED METAL GLOBULES.
Claim 5
Dependent Claim
