    Abstract: An electrical heater and method for heating a catalyst. The heater includes a honeycomb body having intersecting walls forming channels extending along a longitudinal axis. A plurality of electrically resistive paths are included, each including at least a portion of the plurality of intersecting walls and extending a length across the honeycomb body transverse to the longitudinal axis. A positive electrode and a negative electrode are in electrical communication with each other via the resistive paths. The positive electrode and the negative electrode are operatively positioned to generate a respective flow of current through each resistive path. The lengths of at least two of the resistive paths differ from each other. The resistive paths are configured with respect to the at least one positive electrode and the at least one negative electrode such that the current in each of the resistive paths is substantially equal.

    Abstract: A honeycomb extrusion die assembly (10) comprising a honeycomb extrusion die (701) and a forming plate (800) to block batch flow to at least a portion of a skin forming region. The honeycomb extrusion die (701) comprising a step cut discharge surface (758, 760) in the skin forming region and at least some slots (722) each with a divot (312) spaced toward a discharge surface (710) from a feedhole-slot intersection and a wide portion at the discharge surface (710) extending into the die body to the divot (312) to strengthen a peripheral region of a honeycomb extrudate in a reinforcement region, and a bulk nominal section corresponding to a bulk region of the honeycomb body.

    Abstract: An extrusion die (100) for a honeycomb body, the die (100) including: an input surface (102); an opposing output surface (104); feed holes (108) extending from the input surface (102) toward the output surface (104); discharge slots (106) having a slot width (SW) and a slot length (SL), and extending from the output surface (104) toward the input surface (102); and a plenum (130) fluidly connecting the feed holes (108) and the discharge slots (106). The plenum (130) may include chambers (132) connected to the feed holes (108) and including tapered outlets (134) connected to the discharge slots (106). The plenum (133) may include first chambers (132A) connected to the feed holes (108) and including first tapered outlets (134A), and second chambers (132B) connected to the first outlets and including second tapered outlets (134B) connected to the discharge slots (106).
