Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
199 words
An apparatus for forming carbon black pellets comprising: a housing having walls forming a longitudinal chamber extending therethrough, first and second end portions, a carbon black feed inlet and a pelleting fluid inlet positioned at the first end portion, and a pellet outlet positioned at the second end portion; a main conduit for a supplemental fluid extending through the chamber and being rotatably mounted through the housing wall, said main conduit being connected to a source of heated supplemental fluid; a plurality of secondary conduits extending radially outwardly from the main conduit along the length thereof, said secondary conduits being in fluid communication with the main conduit, terminating a preselected spaced distance from an inner surface of the housing wall and being open ended for discharge of said heated supplemental fluid therefrom; means for rotating said main conduit and passing said secondary conduits along said housing wall; means for measuring the temperature in said chamber and generating a signal responsive thereto; means for controlling the temperature of said heated supplemental fluid responsive to said signal for maintaining the temperature in said chamber in a preselected range; and means for moving the carbon black and pelleting fluid through said housing.
Claim 2
Independent Claim
199 words
An apparatus for forming carbon black pellets comprising: a housing having walls forming a longitudinal chamber extending therethrough, first and second end portions, a carbon black feed inlet and a pelleting fluid inlet positioned at the first end portion, and a pellet outlet positioned at the second end portion; a main conduit for a supplemental fluid extending through the chamber and being rotatably mounted through the housing wall, said main conduit being connected to a source of heated supplemental fluid; a plurality of secondary conduits extending radially outwardly from the main conduit along the length thereof, said secondary conduits being in fluid communication with the main conduit, terminating a preselected spaced distance from an inner surface of the housing wall and being open ended for discharge of said heated supplemental fluid therefrom; means for rotating said main conduit and passing said secondary conduits along said housing wall; means for measuring the temperature in said chamber and generating a signal responsive thereto; means for controlling the temperature of said heated supplemental fluid responsive to said signal for maintaining the temperature in said chamber in a preselected range; and means for moving the carbon black and pelleting fluid through said housing.
Claim 3
Dependent Claim
69 words
An apparatus, as set forth in claim 1, wherein there are a plurality of temperature measuring elements positioned along the length of the housing and adapted to measure the temperature within the chamber adjacent the housing walls; and an averaging element connected to the temperature measuring element for receiving a signal responsive to the measured temperature, and delivering a control signal responsive to the average of said received signals.
