Abstract:
A method comprising: a) determining the bow (28) in the extension direction of one or more linear paths on an outer surface or outer surfaces (11,13,14,16) of an extruded ceramic part (10) so that maximum extrusion direction bow (28) of the one of more linear paths or outer surfaces (11,13,14,16) may be determined of the extruded ceramic greenware part (10); b) identifying the linear path on the outer surface or the outer surfaces (11,13,14,16) having maximum convex bow; c) placing the greenware part (10) on a carrier with the linear path on the outer surface or the outer surface location having the maximum convex shape in contact with the carrier; and d) processing the greenware part (10) while disposed on the carrier with the linear path on the outer surface or the surface having the convex shape on the carrier, such that the bow (28) is reduced as a result of the process.

Abstract:
The invention relates to a process and arc oven for bending ceramic flat sheets into ceramic curved sheets by heat treat. The process mainly comprises placing the ceramic flat sheet(s) inside the oven chamber defined by at least a part of electric heating elements which are arranged in an arc; and controlling the heating temperature and time of the oven chamber, making the ceramic flat sheet(s) softening and bending until one surface thereof conforms the arc forming surface which is substantially defined by at least a part of electric heating elements which are arranged in an arc. The main feature of the arc oven according to the invention is that at least a part of electric heating elements are arranged in an arc, and the arc forming surface is made directly from the electric heating elements, or made from the refractories or refractory liner.
Abstract:
A method includes extruding a solid electrolyte composition comprising a plasticizable binder system to form a tubular structure 52. The tubular structure 52 is hollow and open-ended. The method also includes coupling the tubular structure 52 to a mandrel 56 of an end-capping apparatus 50. A portion of the tubular structure 52 protrudes away from a tip of the mandrel 56 such that the portion is not in contact with the mandrel 56. The method further includes inserting the portion of the tubular structure 52 within a cavity 70 of a heater 72 coupled to the end-capping apparatus 50, heating the portion of the tubular structure 52 to a deformation temperature range of the solid electrolyte material, rotating the tubular structure 52 within the heater 72 to shape the portion of the tubular structure, and sealing an end of the tubular structure 52 to form an end-capped tubular structure 92.
Abstract:
The invention relates to an improved method for bending ceramic tiles. The method comprises the stages of making grooves in the lower surface of the tile in the area of the tile to be bent, filling the grooves obtained on the tile with a filling material compatible with the material of which the tile is made, covering the grooves with a flexible strip of incombustible refractory- material, anchoring the strip to the surface of the tile, heating the area of the tile to be bent up to the softening temperature of the area itself and cooling the modelled tile thus obtained.
Abstract:
Methods of adhering graphic film on an irregular substrate are disclosed. The methods includes providing a polymer film composite having two or more layers with at least one layer having a glass transition temperature of at least about 40°C, the polymer film composite having a first side and a second side, and an adhesive layer disposed on the second side. Then the method includes, positioning the adhesive layer against the irregular substrate, heating the polymer film composite, and pressing the heated polymer film against the irregular substrate.
Abstract:
Process for arching stone can be done through the following steps; heating process, coating process required a liquid chemicals, that is epoxy resin, in this process. The function of the use of epoxy resin is to fill micro cracks that arise during this process, bending process, and disposing process. The purpose of this invention is to make arching stone easier and more effiecient.
Abstract:
L'invention concerne un procédé de fabrication d'un panneau sandwich composite, le panneau comportant une âme formée d'une pluralité d'alvéoles qui s'étendent verticalement entre une première peau et une seconde peau, caractérisé en ce qu'il comprend au moins une étape de réalisation d'au moins une première bande (20a) et une seconde bande (20b) dans un matériau fugitif, chaque bande (20a, 20b) présentant au moins une empreinte (30a, 30b, 31b) qui comprend une succession de demi-alvéoles alignées, une étape de tapissage qui consiste à tapisser au moins un pli fibreux (34) sur l'empreinte (30a) de la première bande (20a), une étape d'assemblage de la première bande (20a) et de la seconde bande (20b) qui consiste à imbriquer l'empreinte (30a) de la première bande (20a) avec l'empreinte (31b) de la seconde bande (20b), en emprisonnant ledit pli fibreux (34), et une étape de rognage qui consiste à retirer le surplus de matériau fugitif de l'ensemble des bandes (20a, 20b) formé au cours de l'étape d'assemblage précédente, de façon à former une nouvelle empreinte (38) qui forme une succession de demi- alvéoles (40) alignées.
Abstract:
Figures 25 and 26 show in sequence a 270° bending of a tile predisposed on a bottom surface thereof in which surface a straight groove has been made at a position where a bend is to be performed. Figure 5 is a detailed illustration showing the groove after having been filled following bending. In the illustrated example, the bend of the tile is obtained, after making the groove in the opposite surface to the upper surface, by subjecting the tile to overall or localized heating as it is resting on a support made of refractory material which support has two surfaces which are reciprocally perpendicular and inclined which support has two surfaces which are reciprocally perpendicular and inclined with respect to a vertical, at a suitable angle for the tile to be stable thanks to a part thereof resting on the surface, and a projecting part of the tile to be able, when softened, to fall by gravity until it reaches and rests perfectly on the other surface 10" of the support.
