Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
A CONTINUOUS PROCESS FOR REMOVING OXIDIZABLE VOLATILE MATTER FROM MATERIAL WHICH YIELDS SUCH VOLATILE MATTER UNDER HEAT BY BURNING ALL OF SAID REMOVED VOLATILES WITHIN A SUBSTANTIALLY AIRTIGHT DEVOLATILIZING CHAMBER, COMPRISING CONTINUOUSLY DELIVERING SUCH MATERIAL ONTO A CONTINUOUSLY MOVING IMPERFORATE HEARTH, CONTINUOUSLY REMOVING RESIDUUM FROM THE CONTINUOUSLY MOVING HEARTH, DURING THE TIME DURING WHICH THE MATERIAL LIES UPON THE CONTINUOUSLY MOVING HEARTH CONFINING THE MATERIAL IN A DEVOLATILIZING CHAMBER HAVING A ROOF AND SIDE WALLS AND DURING MOVEMENT OF THE MATERIAL THROUGH SUCH CHAMBER INTRODUCING OXYGEN IN CONTROLLED QUANTITIES ABOVE THE MATERIAL ON THE EARTH AT SPACED POINTS ALONG THE HEARTH AND OXIDIZING THE VOLATILE MATTER WITHIN THE CHAMBER, HEATING THE ROOF AND SIDE WALLS OF THE CHAMBER BY THE HEAT CREATED
Claim 2
Dependent Claim

Claim 3
Dependent Claim
87 words
CONTINUOUS HEAT TREATING APPARATUS COMPRISING AN IMPERFORATE HEARTH OF REFRACTORY MATERIAL, MEANS FORMING A TUNNEL-LIKE DEVOLATILIZING CHAMBER IN WHICH THE HEARTH IN THE CHAMBER, MEANS FOR CONTINUOUSLY DELIVERING ONTO THE ADVANCING HEARTH MATERIAL WHICH YIELDS OXIDIZABLE VOLATILE MATTER UNDER HEAT, MEANS FOR INTRODUCING OXYGEN SOLELY ABOVE THE HEARTH AT SPACED POINTS ALONG THE HEARTH TO OXIDIZE THE VOLATILE MATTER MEANS FOR EXHAUSTING GASES AT SPACED ZONES ABOUT THE HEARTH SOLELY ABOVE THE MATERIAL ON THE HEARTH AND MEANS FOR CONTINUOUSLY DELIVERING RESIDUUM FROM THE CONTINUOUSLY MOVING HEARTH.
