    摘要： Air cross grids, for absorbing scattered secondary radiation and improving radiation imaging in general radiography and in mammography, are provided with a large plurality of open air passages extending through each grid panel. These passages are defined by two large pluralities of substantially parallel partition walls, respectively extending transverse to each other. Each grid panel is made by laminating a plurality of thin metal foil sheets photo-etched to create through openings defined by partition segments. The etched sheets are aligned and bonded to form the laminated grid panel, which is moved edgewise during the radiation exposure to pass primary radiation through the air passages while absorbing scattered secondary radiation arriving along slanted paths.

    摘要： Lightweight beverage containers disclosed herein require less metal per container, exhibit less earing and have one or more of the following features: 1) a reduced seam between the can end and the can body, 2) a side wall having vertically disposed alternating portions of relatively thicker and relatively thinner metal, 3) a can end dimensioned to fit within the domed bottom of a vertically adjacent similar can when stacked, 4) a can body produced from an acircular blank dimensioned to produce said can body without ears, and 5) a can body produced from a cup having a variable radius between the side of said cup and the bottom thereof.

    摘要： Apparatus for detecting the amount of a specific compound in a sample. The apparatus comprises, in combination, a gas chromatograph, a cold trap and a specific gas detector. The cold trap includes means to cool the gas passing therethrough to a predetermined pressure therein, whereby gaseous effluent from the trap substantially consists of the specific gas and an inert gas.
