  • Publication number: 20240104136
    Abstract: Methods, apparatus, and systems for efficient partitioning and construction of graphs for scalable high-performance search applications. A method for partitioning a set of ternary keys having one or more wildcards includes analyzing patterns of the set of ternary keys and storing ternary keys with the same pattern in the same subset. The patterns may include uncompressed patterns and compressed patterns. When there are more patterns than a target number of subgraphs, patterns are repeatedly merged until the number of merged patterns matches the target number of subgraphs. Table entries having ternary keys corresponding to the ternary keys in a final set of merged patterns of ternary keys are generated and partitioned into sub-tables, with each sub-table associated with a respective sub-graph. Tables with hundreds of thousands or millions of entries are supported.

  • Patent number: 11933107
    Abstract: A disc cutter for a cutting unit used in an undercutting operation and a method of producing the same. The disc cutter including an annular disc body made of a metal alloy or metal matrix composite having a first side, a second side arranged substantially opposite to the first side and a radially peripheral part. At least one metal alloy, metal matrix composite or cemented carbide cutting part is mounted in and substantially encircling the radially peripheral part of the disc body which protrudes outwardly therefrom to engage with the rock during the mining operation. The at least one cutting part is made from a material having a higher wear resistance than the material used for the disc body, wherein the disc body and the cutting part are joined by diffusion bonds.

  • Patent number: 7931855
    Abstract: A method of reducing the oxygen content of a powder is provided. A canister is prepared with a getter, filled with the powder to be densified, sealed and evacuated. The canister is subjected to a hydrogen atmosphere at an elevated temperature whereby hydrogen diffuses into the canister through the walls thereof. The hydrogen forms moisture when reacted with the oxygen of the powder and the moisture in the reacted with the getter in order to remove oxygen from the powder to the getter. The atmosphere outside the canister is then altered to an inert atmosphere or vacuum, whereby hydrogen diffuses out of the canister. A dense body having a controlled amount of oxygen can thereafter be produced by conventional powder metallurgy techniques.
