Free-standing thermoplastic bag construction

Abstract: The present invention relates to thermoplastic bag constructions capable of standing in an open and erect position without the extraneous support means normally employed with such bags. The bag is characterized by having a bottom gusset and heat sealed side seams which form the lateral bag edges. The individual walls of the bottom gusset are sealed to the adjacent bag walls utilizing a plurality of spaced apart vertical heat seals which are arranged in a predetermined pattern whereby when the bag is open the bag bottom assumes an elliptical configuration and is self-supporting as a result of the stiffening effect of the vertical heat seals.

Diagenesis of late Proterozoic carbonates; the Beck Spring Dolomite of eastern California

Abstract: Petrographic and compositional attributes of limestone and dolostone in the Beck Spring Dolomite of eastern California indicate that late Proterozoic mineralogies, isotopic compositions, and diagenetic processes were similar to those inferred for younger Phanerozoic marine carbonate sequences. Allochems in limestones include strontium-rich ooids with well-preserved concentric banding and cortices of equant neomorphic calcite that commonly exhibit dissolution and compaction features; cements include microdolomite-rich columnar marine calcite and equant spar. Calcites are depleted relative to dolomites and become enriched with stratigraphic depth. Acicular and columnar marine cement and allochems in dolostones display fabrics identical to those in limestones but are isotopically distinct. Dolomite ooids, columnar and acicular cement, crystal silt, and early luminescent spar cement from four stratigraphic sections define overlapping positive oxygen-carbon covariant fields that trend toward depleted calcite compositions. Early luminescent dolomite spar cement is unconformably overlain by depleted ferroan dolospar. Fabric data suggest that marine cement and ooids were precipitated as magnesian calcite and aragonite. Isotopic data suggest that metastable components locally stabilized to calcite during subaerial exposure while laterally, dolomitization took place in mixed marine-meteoric waters. Early dolospar precipitation began during replacive dolomitization, and late ferroan dolospar precipitated during burial. Lack of evidence for hypersaline conditions suggests that late Proterozoic normal marine carbonate isotopic composition was -0.5 ± 2.018O and +5.3 ± 0.5913C.

Wastebasket and inner liner retainer

Abstract: A wastebasket which is adapted to receive an inner liner includes a container having an upper rim defining an open end, and a lid pivotally mounted on the container and adapted to cover the open end. A bezel is provided for releasably retaining an inner liner in the container. The bezel is pivotally mounted on the container at its open end, and is pivotable between first position, when the bezel is disposed substantially co-planarly with the upper rim of the container, and a second position, where the bezel is raised at an angle above the rim of the container. The wastebasket also includes structure for pivotally mounting the bezel to the container and for retaining the bezel in the raised second position.

Development of Mobil's Fixed-Bed Methanul-to-Gasoline (MTG) Process

Abstract: Mobil recently commercialized its fixed-bed methanol-to-gasoline (MTG) process in a 14, 500 B/D (gasoline) plant, based on natural gas, which is located in New Zealand. Process development studies were carried out in a small pilot plant to define conditions for producing gasoline in good yield and with acceptable product quality while also insuring satisfactory catalyst life. The process was successfully scaled-up by a factor of 100 to a demonstration unit size of 4 B/D. The scale-up factor from the demonstration unit to the commercial plant was in excess of 3000. The characteristics of the fixed-bed MTG process, its development, scale-up to demonstration unit, and assurance of acceptable product quality are discussed.
