| 20100264198 | THERMALLY STABLE POLYCRYSTALLINE ULTRA-HARD CONSTRUCTIONS - Thermally stable polycrystalline constructions comprise a body having a polycrystalline ultra-hard phase and a plurality of empty voids. A population of the voids can be filled with a reaction product. The body is substantially free of a catalyst material. The construction comprises a first support member attached to the body by a first braze material. A second support member is attached to the body and the first support member by a second braze material. The construction may include a third support member attached to the body that is integral or separate from one of the other support members. The braze materials used to attached the support members can be the same or different, as can be the materials used to form the different support members. | 10-21-2010 |
| 20100300767 | Diamond Bonded Construction with Improved Braze Joint - Diamond bonded constructions comprise a body comprising a plurality of bonded together diamond grains with interstitial regions disposed between the grains that are substantially free of the catalyst material used to initially sinter the body. A metallic substrate is attached to the body, and a braze joint is interposed between the body and the substrate. The body is metallized to include a metallic material disposed along a substrate attachment surface in contact with the braze joint, wherein the metallic material is different from the braze joint material. The metallic material may exist within a region of the body extending fully or partially into the body, and/or may exist as a layer extending away from the substrate attachment surface. The body includes a working surface characterized by empty interstitial regions or by interstitial regions filled with an infiltrant material, wherein the infiltrant material is different from the metallizing material. | 12-02-2010 |
| 20110056753 | Thermally Stable Ultra-Hard Material Compact Construction - Thermally stable ultra-hard compact constructions of this invention comprise an ultra-hard material body that includes a thermally stable region positioned adjacent a surface of the body. The thermally stable region is formed from consolidated materials that are thermally stable at temperatures greater than about 750° C. The thermally stable region can occupy a partial portion of or the entire ultra-hard material body. The ultra-hard material body can comprise a composite of separate ultra-hard material elements that each form different regions of the body, at least one of the regions being thermally stable. The ultra-hard material body is attached to a desired substrate, an intermediate material is interposed between the body and the substrate, and the intermediate material joins the substrate and body together by high pressure/high temperature process. | 03-10-2011 |
| 20110127088 | POLYCRYSTALLINE ULTRA-HARD COMPACT CONSTRUCTIONS - Polycrystalline ultra-hard compact constructions comprise a polycrystalline ultra-hard compact having a polycrystalline ultra-hard body attached to a substrate. A support member is attached to the compact by a braze material. The support member can have a one-piece construction including one or more support sections. The support member has a first section extending axially along a wall surface of the compact, and extending circumferentially along a portion of the compact. The support member can include a second section extending radially along a backside surface of the compact, and/or a third section extending radially along a front side surface of the compact. In one embodiment, the support member includes a second and/or third section and the compact disposed therein is in an axially compressed state. The support member is interposed between the compact and an end-use device, and improves the compact attachment strength to an end-use device when compared to conventional compacts. | 06-02-2011 |
| 20110139514 | Thermally Stable Diamond Bonded Materials and Compacts - Thermally stable diamond bonded construction comprise a diamond bonded body including a thermally stable region, comprising a plurality of diamond grains bonded together by a reaction product of the diamond grains with a reactant such as Si, and a polycrystalline diamond region, comprising intercrystalline bonded diamond and a catalyst material. The body further comprises a ceramic compound formed by reaction of an Nb, Zr, Ti, or Mo getter material with a gaseous element generated during HPHT sintering of the diamond bonded body. The diamond bonded body may comprise from 0.1 to 15 percent by weight of the ceramic compound. The diamond bonded body can be formed during a single HPHT process operated at different temperatures when the reactant has a melting temperature above the catalyst material. The construction may include a metallic substrate attached to the diamond bonded body to facilitate use as a wear or cutting element. | 06-16-2011 |

| 20100213085 | APPARATUS, SYSTEM, AND METHOD FOR SELECTIVELY MIXING TWO SUBSTANCES - An apparatus and method for storing, mixing, and delivering a powder solid and a fluid such as baby formula and water without the risk of product contamination or of the product expiring. The apparatus includes a first compartment, a second compartment, a passage in a bottom of the first compartment, and a seal that seals the passage in the bottom of the first compartment. Communication between the first compartment and the second compartment is achieved by longitudinally displacing the second compartment with respect to the first compartment. The longitudinal displacement of the second compartment causes the second compartment to be withdrawn from the first compartment. The seal is attached to the top of the second compartment such that the displacement of the second compartment with respect to the first compartment causes the seal to be displaced from the passage. | 08-26-2010 |
| 20100213156 | APPARATUS AND METHOD FOR MIXING INFANT FORMULA - An apparatus and method for storing, mixing, and delivering a powder solid and a fluid such as baby formula and water without the risk of product contamination or product expulsion to the surrounding environment. The apparatus is used by placing the powder formula into a specially designed compartment, joining the compartment with another compartment configured to store a liquid, filling the second compartment with a liquid, and sealing the system together. Once mixing and activation is completed, the two compartments are twisted in relation to one another, and the two separate substances are now allowed to flow freely and mix. The product can now be served to the child. | 08-26-2010 |
