  • Patent number: 9802337
    Abstract: Technique to provide an abrasive regeneration method which, from a used abrasive, can recover an abrasive by an efficient method and can thereafter obtain a high-purity regenerated abrasive by a simple method. This abrasive regeneration method uses an abrasive comprising at least one type of abrasive selected from diamond, boron nitride, silicon carbide, alumina, alumina zirconia, zirconium oxide and cerium oxide. The abrasive regeneration involves a slurry recovery step (A) for recovering an abrasive slurry discharged from a polishing machine, a separation and concentration step (B) for adding an alkaline earth metal salt as an inorganic salt to the recovered abrasive slurry to aggregate the abrasive, and separating and concentrating the abrasive from a mother liquor, an abrasive recovery step (C) for recovering the separated and concentrated abrasive, and a second concentration step (D) for filter-treating the concentrated abrasive.

  • Publication number: 20130174607
    Abstract: A method and system for preparing polysilicon slim rods, the method and system including: placing a piece of polysilicon on a fixture; applying a predetermined laser beam or abrasive jet to the piece of polysilicon; and separating a polysilicon slim rod from the piece of polysilicon. The laser beam may be used for either cutting or for cracking depending on the operating parameters chosen. There may also be various combinations of cutting and cracking used in order to separate the slim rod from the piece of polysilicon. For example, the laser cut may be a scribing and/or partial cut and the separation may be completed by cracking the remaining silicon. In this case, the cracking may be accomplished by, for example, mechanical bending or laser cracking. Generally speaking, a laser beam used for cracking may be different from and have differing operating parameters from a laser beam used for cutting.

  • Patent number: 8419506
    Abstract: A dual capability ultra high pressure (UHP) fire attack system includes a fluid jet assembly and an UHP attack line system. The fluid jet assembly and the UHP attack line system are coupled to a high pressure fluid source. The fluid is discharged from both the fluid jet assembly and the UHP attack line system as a mist have a droplet diameter of approximately 150 microns. When infused with an abrasive material, the fluid jet assembly may be used to cut through structural surfaces, so that a fire may be “knocked down” before the fuel source is attacked.

  • Publication number: 20130043009
    Abstract: A component is provided and includes a substrate comprising an outer and an inner surface, where the inner surface defines at least one hollow, interior space. The component defines one or more grooves, where each groove extends at least partially along the outer surface of the substrate and has a base and a top. The base is wider than the top, such that each groove comprises a re-entrant shaped groove. One or more access holes are formed through the base of a respective groove, to connect the groove in fluid communication with the respective hollow interior space. Each access hole has an exit diameter D that exceeds the opening width d of the top of the respective groove. The diameter D is an effective diameter based on the area enclosed. The component further includes at least one coating disposed over at least a portion of the surface of the substrate, wherein the groove(s) and the coating together define one or more re-entrant shaped channels for cooling the component.
