    Abstract: A honeycomb extrusion apparatus includes first and second vanes with respective first and second face portions. First and second axial widths of a circumferential feed area are respectively defined between the first and second face portions and the outer feed surface of the die body. In further examples, methods include the steps of selectively adjusting the first axial width and the second axial width of the circumferential feed area by respectively adjusting the first and second vane relative to the mask. In further examples, a honeycomb extrusion apparatus includes a plurality of mask segments that each includes an inner peripheral surface portion. Each of the plurality of mask segments are independently adjustable along a respective radial axis.

    Abstract: A control strategy for producing high quality extrudates, including the steps of monitoring the temperature of a ceramic precursor batch by measuring the temperature of the batch material either directly or indirectly by measuring the temperature of a component of the extruder proximate to the die and transmitting the temperature data to an extrusion control system which comprises a master controller (106), at least one slave controller (110) and an optional supervisory controller. The supervisory controller determines batch temperature setpoint (102) in order to achieve the desired temperatures for extruding a certain type of batch material based on real time temperature inputs and stored parameters such as batch composition, process throughput, extruder cooling capacity, and the like. The master controller (106) receives batch temperature setpoint from the supervisory controller, and monitors batch temperature and in turn regulates at least one slave controller (110) which controls the flow of coolant (112) to portions of an extruder (114) in contact with the batch material.

    Abstract: The present invention is directed to a bi-stable coupling for controlling the depth of a tool insertion, such as drilling, and similar processes. The bi-stable coupling can be used to penetrate (e.g., drill or push) through a material layer of unknown thickness without plunging the tool into the adjacent layer. In accordance with the invention, in a first state, force is applied to the tool to initiate penetration and a reactive force maintains the device in the first state during penetration and when tool penetrates the material, the reactive force is diminished enabling the device to transition to a second state in which the tool becomes retracted. In medical applications, the invention allows for drilling through bone of unknown thickness without plunging into the adjacent soft tissue.
