Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
In a sealed tap system for the discharge of molten material from a chamber, comprising a downwardly inclined refractory conduit communicating with an opening in said chamber, said conduit adapted to discharge molten material across a lip protruding from the discharge end of said conduit into a chamber immersed in a liquid whereby said molten material is rapidly quenched by said liquid, the improvement which comprises providing heating means adapted to maintain the fluid flow of an upper portion of molten material in said conduit and cooling means adapted to congeal a portion of flowing molten material adjacent the refractory conduit so as to reduce the corrosion of the refractory.
Claim 2
Dependent Claim
110 words

Claim 3
Dependent Claim
30 words
An improvement as set forth in claim 1, wherein said heating means comprises a burner adapted to discharge hot gases of combustion over the upper portion of said molten material.
Claim 4
Dependent Claim
25 words
An improvement as set forth in claim 1, wherein said cooling means is in sufficient proximity to the protruding lip to maintain the integrity thereof.
Claim 5
Dependent Claim
22 words
An improvement as set forth in claim 3, wherein said cooling means comprises a container adapted for the circulation of water therethrough.
