A reduced weight, reduced density gypsum panel that includes high expansion vermiculite with fire resistance capabilities that are at least comparable to (if not better than) commercial fire rated gypsum panels with a much greater gypsum content, weight and density.

The invention relates to a method and to a corresponding system for providing a dental prosthesis made from ceramic material having a colour matched to the patient comprising the following steps: (i) receiving a desired nominal colour for the dental prosthesis, determining a deviation between the nominal colour and actual colour of the sintered ceramic material by the control unit and defining a temperature time cycle having a cycle time suitable for compensation of the deviation, for sintering at a defined sintering temperature and creating a corresponding sintering program by the control unit; and (ii) adjusting the actual colour of the selected ceramic material to the nominal colour in the sintering furnace by the sintering program executed by the sintering furnace.

A ceramic fiber processing apparatus and method for processing ceramic fibers for the manufacture of ceramic matrix composites (CMCs) is provided. The apparatus includes a frame including a plurality of unidirectional ceramic fibers wound thereabout and extending across a void therein the frame to define a first planar array of ceramic fibers and a second planar array of ceramic fibers. During use, the frame is disposed in the ceramic fiber processing apparatus in a manner to enable gripping of the first planar array of ceramic fibers with a first gripper assembly and gripping of the second planar array of ceramic fibers with a second gripper assembly. A cutting mechanism provides cutting of the plurality of unidirectional ceramic fibers to separate the first planar array of ceramic fibers and the second planar array of ceramic fibers from one another.

A method for producing a honeycomb structure for fine particle collection filters. The honeycomb structure includes a plurality of porous honeycomb segments joined together via joining material layers. The method includes the steps of: forming the outer peripheral wall of each of the porous honeycomb segments so as to have a thickness thicker by a grinding margin; drying the porous honeycomb segments each formed by grinding the outer peripheral wall so as to have the thickness thicker by the grinding margin; firing the dried porous honeycomb segments; grinding and removing the grinding margin of the outer peripheral wall of each of the fired porous honeycomb segments; and applying a joining material to each of the porous honeycomb segments with the grinding margin ground and removed, between joining surfaces of each of the porous honeycomb segments, to join the porous honeycomb segments via the joining material layers.

A GDL cutting system of a fuel cell includes: a laser-cutting device that forms a gas diffusion layer by radiating a laser on the surface of a GDL fabric panel moving on a conveyer; an adsorbing-conveying device that adsorbs and conveys at least two gas diffusion layers cut by the laser-cutting device; a first vision sensor that senses an upper side of the gas diffusion layers cut by the laser-cutting device; and a second vision sensor that senses a lower side of the gas diffusion layers adsorbed and conveyed by the adsorbing-conveying device.
