Publication number: 20190331243Abstract: A drill piping or tubing pressure seal includes a diameter-spanning body portion. The diameter-spanning body portion includes a high-pressure side, a low-pressure side and a plug receptacle passing through the diameter-spanning body portion from the high-pressure side to the low-pressure side. The high-pressure side and the low-pressure side of the diameter-spanning body portion include a protective coating; however, an interior surface of the plug receptacle located between the high-pressure side and the low-pressure side does not include the protective coating. In addition, a plug is configured to be located within the plug receptacle, and the plug is configured to be retained within the plug receptacle by an anchor element to maintain the plug within the plug receptacle until a breakaway force of the anchor element is exceeded. A gasket is located between a portion of the plug and the plug receptacle.Type: ApplicationFiled: April 23, 2019Publication date: October 31, 2019Applicant: CoorsTek, Inc.Inventor: Patrick Stone

Patent number: 10305116Abstract: The present invention relates to a protonic ceramic fuel cell and a method of making the same. More specifically, the method relates to a cost-effective route which utilizes a single moderate-temperature (less than or equal to about 1400° C.) sintering step to achieve the sandwich structure of a PCFC single cell (dense electrolyte, porous anode, and porous cathode bone). The PCFC layers are stably connected together by the intergrowth of proton conducting ceramic phases. The resulted PCFC single cell exhibits excellent performance (about 450 mW/cm2 at about 500° C.) and stability (greater than about 50 days) at intermediate temperatures (less than or equal to about 600° C.). The present invention also relates to a two step method for forming a PCFC, and the resulting PCFC.Type: GrantFiled: February 12, 2015Date of Patent: May 28, 2019Assignees: Colorado School of Mines, CoorsTek, Inc.Inventors: Jianhua Tong, Meng Shang, Ryan Patrick O'Hayre, Sophie Menzer, W.

Patent number: 10000422Abstract: The present invention provides a ceramic to ceramic joint and methods for making such a joint. Generally, the joint includes a first ceramic part and a second ceramic part, wherein the first and second ceramic parts each include a ceramic-carbide or a ceramic-nitride material. In some cases, an aluminum-initiated joint region joins the first and second ceramic parts. This joint region typically includes chemical species from the first and second ceramic parts that have diffused into the joint region. Additionally, the first and second ceramic parts each typically include a joint diffusion zone that is disposed adjacent to the joint region and which includes aluminum species from the joint region that have diffused into the joint diffusion zone. Other implementations are also described.Type: GrantFiled: May 11, 2015Date of Patent: June 19, 2018Assignee: CoorsTek, Inc.Inventors: Joseph R Fellows, Merrill Wilson

Patent number: 9975811Abstract: A sintered ceramic ball is described that includes an incomplete ceramic ball portion with a wall with an exterior surface, the wall having an interior space located radially interior of an inner surface of the wall. The incomplete ceramic ball portion also has an exterior surface, the exterior surface having an exterior surface area. The sintered ceramic ball further includes a ceramic plug joined with the incomplete ceramic ball portion to form a continuous exterior ball surface. The ceramic plug includes an exterior plug surface and a plug wall. The plug surface includes an exterior plug surface area, wherein the exterior plug surface area is between about 5% to 49.9% of the sum of the exterior surface area of the incomplete ceramic ball portion and the exterior plug surface area. The interior space of the sintered ceramic ball is sealed within the wall and the plug wall.Type: GrantFiled: June 12, 2015Date of Patent: May 22, 2018Assignee: CoorsTek, Inc.Inventor: Donald Robert Giovanini
