Patent number: 6076318Abstract: An arcuate structure containing at least sixty six-sided building blocks, and said six-sided building blocks are independently able to provide means for connecting one of said six-sided building blocks to at least one of said six-sided building blocks. The outside face of the six-sided block has a substantially rhomboidal shape, and is substantially parallel to the inside face of the six-sided block. The right edges and the left edges have equal lengths and form equal angles with the inside face and outside face. The left and right sides of the six-sided block are congruent with each other, are in the shape of a parallelogram, and contain two recesses and two projections within their borders.Type: GrantFiled: February 22, 1999Date of Patent: June 20, 2000Assignee: PolyCeramics, Inc.Inventors: Thomas J. Grimm, Peter A. Roberts

Patent number: 5873206Abstract: An arcuate building structure containing at least three five-sided building blocks, at least three six-sided building blocks, and said five-sided and six-sided building blocks are independently able to provide means for connecting one of said five-sided building blocks to at least one of said six-sided building blocks. The top side of the six-sided block has a substantially triangular shape, and is substantially parallel to the bottom side of the six-sided block. The front side of the six-sided block has a substantially trapezoidal shape with a top edge, a bottom edge, a right edge, and a left edge. The right edge and the left edge have equal lengths and form equal angles with the bottom edge. The back side of the six-sided block has a substantially triangular shape with at least two sides equal in length to each other. The left and right sides of the six-sided block are congruent with each other, are in the shape of a parallelogram, and contain a recess and projection within their borders.Type: GrantFiled: May 6, 1997Date of Patent: February 23, 1999Assignee: PolyCeramics, Inc.Inventor: Peter A.

Patent number: 5705118Abstract: A process for preparing a ceramic body in which a ceramic mixture is formed into a green body and thereafter fired. The ceramic mixture is prepared by mixing at least about 40 weight percent of ceramic material and less than about 60 weight percent of gluten with water. At least about 90 weight percent of the particles of ceramic material are smaller than about 20 microns, and at least about 50 weight percent of the particles of ceramic material are from about 0.5 to about 2 microns. The mixture has a pH of from about 2 to about 8.Type: GrantFiled: March 22, 1994Date of Patent: January 6, 1998Assignee: PolyCeramics, Inc.Inventors: Kevin G. Hayes, Peter A. Roberts, Frank R. Spitulnik

Patent number: 5560151Abstract: A building structure which contains a hexagonal building unit and a pentagonal building unit joined together by a plug. There are six triangularly-shaped building blocks in the hexagonal unit, and the base angles of these building blocks is from about 60.6 to about 60.8 degrees. There are five triangularly-shaped building blocks in the pentagonal unit, and the base angles of these building blocks is from about 54.5 to about 54.7 degrees.Type: GrantFiled: March 6, 1995Date of Patent: October 1, 1996Assignee: PolyCeramics, Inc.Inventor: Peter A. Roberts

Patent number: 5458837Abstract: A process for preparing a porous ceramic body in which a green body containing at least 60 weight percent of ceramic material, at least about 25 weight percent of water, and from 5 to 40 weight percent of gluten is formed. The green body is dried until it contains less than about 0.5 weight percent, and it is then heated to a temperature of from 1,100 to 3,200 degrees Fahrenheit until substantially all of the gluten has been removed.Type: GrantFiled: November 23, 1993Date of Patent: October 17, 1995Assignee: PolyCeramics, Inc.Inventors: Peter A. Roberts, Kevin G. Hayes

Patent number: 5329737Abstract: An arcuate building structure containing at least three five-sided building blocks, at least three six-sided building blocks, and means for connecting one of said five-sided building blocks to at least one of said six-sided building blocks. The top side of the six-sided block has a substantially triangular shape, and is substantially parallel to the bottom side of the six-sided block. The front side of the six-sided block has a substantially trapezoidal shape with a top edge, a bottom edge, a right edge, and a left edge. The right edge and the left edge have equal lengths and form equal angles with the bottom edge. The back side of the six-sided block has a substantially triangular shape with at least two sides equal in length to each other. The left and right sides of the six-sided block are congruent with each other, are in the shape of a parallelogram, and contain a recess within their borders.Type: GrantFiled: October 15, 1993Date of Patent: July 19, 1994Assignee: PolyCeramics, Inc.Inventors: Peter A.

Patent number: 5298205Abstract: A process for preparing a porous ceramic material, is disclosed. The process uses an organic sponge material, and a ceramic slurry. The ceramic slurry contains liquid, gluten, and ceramic material.In the first step of the process, the ceramic slurry is applied to the sponge in order to substantially saturate it with slurry. Thereafter, the saturated sponge is dehydrated until it contains less than about 5.0 weight percent of liquid. The dehydrated sponge is then fired at a temperature of from about 1,100 to about 3,500 degrees Fahrenheit.Type: GrantFiled: August 27, 1992Date of Patent: March 29, 1994Assignee: PolyCeramics, Inc.Inventors: Kevin G. Hayes, Peter A. Roberts

Patent number: 5296180Abstract: A process for preparing a hollow, porous ceramic material is provided. In the first step of the process, a substrate which will burn out (vaporize) at a temperature of 1,100 degrees Fahrenheit (and which, preferably, is carbonaceous) is provided. This substrate is coated with a mixture of gluten, ceramic material, and water. The coated substrate is then dried to a moisture content of less than about 0.5 weight percent and, thereafter, heated to a temperature of from about 1,100 to about 3,200 degrees Fahrenheit to cause the substrate to burn out and the coating to sinter.Type: GrantFiled: May 11, 1992Date of Patent: March 22, 1994Assignee: PolyCeramics, Inc.Inventors: Kevin G. Hayes, Peter A. Roberts
