  • Patent number: 11326100
    Abstract: The disclosure relates to a scintillator and a radiation detector including the scintillator. The scintillator includes a scintillator material. In an embodiment, the scintillator material can include a metal halide doped with Eu2+ and co-doped with Sm2+. The metal halide can include at least one halogen selected from Br, Cl, and I. In an embodiment, the metal halide can include at least one element selected from alkaline-earth metals, rare-earth elements, Al, Ga, and the alkali metals selected from Li, Na, Rb, Cs. In a particular embodiment, co-doping with Sm2+ can shift the scintillation light emission peak to a region of the emission spectrum having a low self-absorbance of the scintillator material.

  • Patent number: 8671692
    Abstract: A combustor assembly includes a convergent segment followed by a divergent segment to advantageously improve combustion. The combustor assembly includes a first segment beginning at a forward end that transitions to a second segment past a transition segment in a direction along a combustor axis toward an aft end. The reduction in cross-sectional area within the first segment provides desirable fuel and air mixing properties. The convergent first segment in combination with the divergent second segment decreases residence time of fuel-air mixture within the combustor chamber that decreases production of undesirable emissions from the combustor assembly.

  • Patent number: 4072233
    Abstract: A container includes a plurality of walls that define an enclosed space. One of the container walls has a frangible piercing point thereon adapted to be penetrated by an extraction device such as a drinking straw, the piercing point being defined by a depression formed in the exterior surface of the container wall, but which does not penetrate completely through the wall. The depression is surrounded by an annular ring, which marks its location, and the container walls are preferably made of a plurality of layers of laminated material.
