An extrudate transport apparatus comprises a free floating roller assembly, wherein the roller assembly controls a rotational pitch of a cylindrical green ceramic extrudate as the green ceramic extrudate moves longitudinally from a first location to a second location within the extrudate transport apparatus. The free floating roller assembly has a predetermined effective weight and comprises a contact roller having a deformable outer surface for frictionally contacting an outer surface of the green ceramic extrudate in motion adjacent thereto, while maintaining a constant contact force upon said green ceramic extrudate.

A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body, the non-fired honeycomb formed body including a raw material composition containing a ceramic raw material and water; an induction drying step of drying the manufactured non-fired honeycomb formed body by induction drying to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The induction drying step is to remove 10 to 50% of the entire water that the non-fired honeycomb formed body contained before drying by induction drying to obtain a first dried honeycomb formed body, then turn the first dried honeycomb formed body upside down and remove the residual water by further induction drying to obtain the honeycomb dried body.

A pre-cast concrete stair tread is provided where the stair tread has reinforced corrugated metal embedded within the core of the concrete stair tread. The corrugations are lined up along the elongated direction of the stair tread. Concrete is poured and cured over at least one side of the corrugated metal. Additionally, the pre-cast concrete stair tread may have one or more metal straps fixed on the reinforced corrugated metal in a direction perpendicular to the corrugations and the elongated direction.

A molded concrete U-wall construction block including a molded concrete U-wall construction block structure formed from cured concrete poured about a block cage made from reinforcing material during a block manufacturing process. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

Device and process for picking up a formable and/or collapsible part (30) that employs the forces of a vacuum (44) and generally distributes the vacuum force uniformly over a large portion of the surface of the part (30). The device preferably provides support for the part (30) at regular intervals, for example using a distributor plate (14) having many small openings (26). The device preferably employs a porous layer (12) such as an open cell foam between the distributor plate (14) and the part (30). The porous layer (12) may perform for one or any combination of the following: further distribute the vacuum forces, cushion the part (30) against the distributor plate (14), or further distribute the support for the part (30).

Disclosed herein is a method and apparatus for back end control of translation and rotation of green ware (e.g., producible from ceramic extrudate). A green ware handling system (102) includes a back end assembly (129) that contacts a back end face (118B) of a green ware (116) and moves to push the green ware (116) along the support channel (114). In certain embodiments, the green ware handling assembly (102) includes a leading end assembly (128) to pull the green ware (116) and then transfer control to the back end assembly (129), which translates and also optionally rotates the green ware (116). This handoff increases the overall production rate of the green ware (116). In certain embodiments, the back end assembly (129) penetrates the back end face (118B) of the green ware (116) with cleat penetration features (312) to provide a secure engagement with the green ware (116) to rotate and translate the green ware (116) while also decreasing a depth of damage to the green ware (116).
