Friction reducing additives and compositions thereof

Abstract: Certain borated additive compounds, such as borated mixed ethoxylated amines and ethoxylated amides or hydroxyalkyl imidazolines and hydroxyesters or hydrolyzed hydroxyalkyl imidazolines and ethoxylated amides and combinations thereof, provide highly effective multifunctional characteristics for various lubricating media into which they are incorporated.

Selective production of para-xylene

Abstract: Process for the selective production of para-xylene by methylation of toluene in the presence of a catalyst comprising a crystalline aluminosilicate zeolite, said zeolite having a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12 which catalyst has undergone prior treatment with steam to reduce the alpha value thereof to less than about 500 and preferably within the range of less than about 20 but greater than zero.

Flexible plastic zipper slider with rigidizing structure for assembly with profiled plastic zipper

Abstract: A flexible plastic slider having sidewalls normally diverging outwardly and spaced apart a distance adequate for transverse installation of the slider over the profiled elements of a zipper with rigidizing structure on the slider to move the sidewalls into and retain them in an assembled position on the zipper to prevent the slider from being lifted off the zipper.

Tide-Dominated Estuarine Facies in the Hollin and Napo ("T" and "U") Formations (Cretaceous), Sacha Field, Oriente Basin, Ecuador

Abstract: The article by Shanmugam et al. (2000) is a welcome addition to the scant sedimentological literature on the Oriente Basin and its continuation in Colombia, the Putumayo Basin (Higgs, 1997a). Shanmugam et al. (2000) reinterpreted the Hollin and Napo T-U sands as tide-dominated estuarine deposits, rejecting a previous deltaic model. Neither model, however, accords with the stated lack of evidence for subaerial emergence. An alternative, tidal shelf interpretation is promoted here, and petroleum reservoir implications discussed. Also, although Shanmugam et al. (2000) did not report any sequence boundaries, their data suggest that angular (tectonic) sequence boundaries occur at the base of the A and B limestones, signifying possible incised valleys cutting into the U and T sands, again important for oil exploration. ### Lack of Emergence Indicators The 516 ft (157 m) of cores from seven wells examined by Shanmugam et al. (2000) show a simple facies association of shales, heterolithics, and cross-bedded sands. "[N]o evidence for subaerial exposure" exists (Shanmugam et al., 2000, p. 674); for example, "rooting is lacking" (Shanmugam et al., 2000, p. 660) and no coal beds, paleosoils, or desiccation cracks were reported. Sparse interpreted marsh deposits (<1% of one 58 ft core) (Shanmugam et al., 2000, table 2) are based on nondiagnostic interpretation criteria, that is, sandstone with "intervals of concentrated carbonaceous fragments … may be interpreted as a marsh environment" (Shanmugam et al., 2000, p. 660). Alternatively, such plant-flake concentrations could occur on a shelf because of tidal-current segregation of particles. An interpreted "fluvial channel" is based solely on "cross-stratification and basal lags" (Shanmugam et al., 2000, p. 656), both of which can also apply to submarine tidal bars (e.g., Stride et al., 1982, figure 5.22; Dalrymple, 1992, figure 29C). The same facies association and absence or scarcity of emergence indicators characterizes the Hollin and Napo T-U …
