  • Patent number: 10941941
    Abstract: A center body assembly for a lean direct injection fuel injector is disclosed. The center body assembly defines a primary liquid passage, a liquid gallery, a liquid main first passage, a liquid main second passage, and an atomizer assembly. The primary liquid passage supplies liquid fuel to the liquid gallery. The liquid gallery aligns with the primary liquid passage and distributes fuel to the liquid main first passage, and subsequently to the liquid main second passage. The atomizer assembly is in flow communication with the liquid main second passage and provides atomized fuel for combustion.

  • Patent number: 10247155
    Abstract: A fuel injector for a combustion engine includes an injector head including a nozzle, a premixer, and a distributor structured to distribute a plurality of different fuels to different sets of fueling orifices in the premixer. A pilot assembly of the fuel injector is coupled to the premixer and includes a first fueling passage for a first fuel and a second fueling passage for a second fuel. Multiple sets of fueling orifices are positioned within the fuel injector, the fueling orifice sets being selectively connectable to a plurality of different fuel supplies, and both located and sized so as to accommodate a wide range of flow rates to enable a combustion engine coupled with the fuel injector to operate on fuels having a range of Wobbe numbers and compositions.

  • Publication number: 20080107818
    Abstract: An apparatus for scraping the surface of a sink roll in a molten metal coating process comprises a support member having a pair of linearly movable arms supported thereon. The support member depends from a bridge structure spanning a continuous metal coating line, and a pair or arms, the arms being disposed on opposite sides of said support member. Each arm has a scraper assembly portion attached thereto. Each scraper assembly portion has two blades affixed thereto, a forward scraper blade and a rear scraper blade, with a connecting portion connecting the two blades. The connecting portion also has a first pivot point for attaching the connecting portion to the arm associated with the scraper assembly portion, the first pivot point being disposed between said forward and rear scraper blades for following the radial contours of the roll surface. A second pivot point permits the blades to follow the crown of the roll.

  • Publication number: 20070219982
    Abstract: Systems and methods for preparing electronic searches are disclosed. In situations involving large number of items for many models of products, searches can be burdensome to the database. Moreover, variations in user skills can make many search requests inefficient and even meaningless. In one embodiment, search requests from users are prepared at a web server so as to form a more focused and meaningful search query for the database. Because such computing resource investments can be made at one or more servers, burden of heavy search loads can be distributed to the servers from the database. Various techniques for forming search queries can include translating abbreviations, nomenclatures, and misspellings. Moreover, use of standardized words allows for more efficient searches. In one embodiment, large number of automobile parts can be searched efficiently by prioritized matching of vehicle model information and part information from a search request in forming the search query.

  • Publication number: 20060023758
    Abstract: A nonlinear Yb:YAB laser material is disclosed. The material is capable of generating fundamental o-polarized first wavelength laser light and frequency doubled e-polarized second wavelength laser light, the material being oriented for type 1 phase matching of the first wavelength laser light. Also disclosed is a laser system. The system comprises a pumping light source emitting a pumping beam of light, a laser cavity having an input coupler operatively disposed with respect to the light source so as to couple the pumping beam of light into the cavity, and a nonlinear Yb:YAB laser material capable of lasing in response to a pumping beam of light thereby generating fundamental o-polarized first wavelength laser light and frequency doubled e-polarized second wavelength laser light, the material being oriented for type 1 phase matching of the first wavelength laser light, the first wavelength laser light being in the range of 1020-1100 nm and the second wavelength laser light being in the range of 510-550 nm.

  • Publication number: 20050079997
    Abstract: A method for joining tissue comprising aligning and abutting edges of the tissue to be joined applying a biodegradable, biological solder or an analogue thereof, across the edges and exposing the solder to an energy source under conditions which provide transfer of energy from the source to the solder to cause the solder to bond to the tissue surface adjacent the edges to provide a weld holding the edges together.
