Abstract:
An object is extruded to have the form of a cage, the cage defined by spokes corresponding to several extrudate streams. The spokes bound a hollow interior and extend between opposed hub regions where the spokes are fused together. In manufacturing the objects, ceramic material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of extrudate streams exiting the dies.
Abstract:
Masonry units, such a blocks, are fabricated in a sequential process, using improved mold structures, such as within a production corridor of a corresponding fabrication system. A compressible masonry feedstock or formula, which can be de-agglomerated before use, is filled within a block mold having releasable elements. The formula is then compressed within the mold structure. The compressed workpiece can be further processed, such as for any of final height adjustment, the establishment of a surface feature, or to remove cores. The block mold, having releasable elements or sides, such as using hinges or springs, is released from the formed block, wherein the formed masonry unit can be removed for curing, and wherein the block mold can be reused to fabricate a subsequent masonry unit.
Abstract:
Methods for threading ceramic materials, such as ceramic materials used for spinal implants or other biomedical implants. In some implementations, an expected rate of shrinkage of the block upon undergoing a firing process may be determined. A scaling factor may then be applied using the expected rate of shrinkage to select a tap having a size larger than a desired thread size. A green block may then be tapped with the selected tap to form a threaded opening in the green block. The block may be machined in order to remove cracks caused by the tapping process and/or to form the block into a desired shape/size. The green block may then be fired, which may result in a reduction of a size of the block and a size of the threaded opening.
Abstract:
Provided herein is an apparatus for taking out a molded product that can inform a user of the air consumption and the electric power consumption matching the set conditions without using measuring devices and that allows the user to set conditions that reduces the total energy consumption. A consumption computing section computes an air consumption and an electric power consumption per one molding cycle based on conditions set for a plurality of air driven devices and conditions set for a plurality of electric devices input from a controller and individual air consumption information and individual electric power consumption information stored in a consumption information storage section. A display control section causes a display section to display the air consumption and the electric power consumption computed by the consumption computing section.

Abstract:
A powder rapid prototyping method includes steps of forming a thin layer 35a of a powder material, irradiating a heating energy beam to a specific region of the thin layer 35a of the powder material to thereby form a preliminary heating layer 35c whose temperature is elevated, and irradiating the heating energy beam to an inside region of the preliminary heating layer 35c whose temperature is elevated to melt and then solidify the thin layer 35a of the powder material to thereby form a solidified layer, wherein the respective steps are repeatedly implemented to fabricate a rapid prototyping model 51, 52.

Abstract:
Methods and apparatus for the manufacturing of prestressed reinforced concrete railroad ties in which the apparatus consists of an elongated spine or compression member which has no foundation but rather is independent of the supporting surface upon which it rests. In one version of the apparatus two bridge members confront the opposite ends of the spine and permanent tension resisting members pass beneath the spine from end to end of the spine and are attached to the lower ends of the bridge members. In another version two structural members are embedded in the concrete of the spine and protrude to provide terminal members.
