Manufacture of plastic bags with interlocking profile extrusions

Abstract: In the manufacture of plastic bags having interlocking profiled extrusions for the closure, the extruded plastic profile is applied to the moving web of film immediately after extrusion of the profile. The temperature of the moving web is maintained such that the profile adheres to the moving web upon contact and thereafter cools to set the thermoplastic in the desired profile. The moving web of film is maintained under tension so that contraction of the film upon release compensates for the contraction of the locking profile as it cools to prevent puckering of the web. The locking profile is applied to the web in an in-line process which includes folding and heat sealing the moving web of film to form plastic bags.

Organic matter metabolizability andd calcium carbonate dissolution in nearshore marine muds

Abstract: Examination of intertidal mud flat and tidal creek sediments from Sapelo Island, Georgia, and Indian Neck, Connecticut, indicates that variations in the degree of calcium carbonate preservation exist between these localities. Although the preservation of calcium carbonate in modern nearshore terrigenous marine muds has previously been shown to be strongly dependent on the physical and biological attributes of the depositional environment (Berger and Soutar 1970; Sholkovitz 1973; Aller 1982), the phenomenon documented in this study occurs in the absence of significant variations in benthic faunas or physical conditions. Evidence for variations in the degree of calcium carbonate preservation is provided by analyses of sediment chemistry and observations of mollusc shells recovered from he sediments. The pattern of sediment chemistry and calcium carbonate preservation is shown to be related to seasonal climatic variations and the metabolizability of organic matter supplied to the sediments. During the summer the presence of readily metabolizable organic matter in the Connecticut sediments results in high rates of microbial decay, establishment of anoxic-sulfidic conditions at the sediment-water interface, and the production of large amounts of ferrous sulfide minerals. During periods of reduced microbial activity (winter), ferrous sulfide minerals in the surficial sediments are oxidized, resulting in dramatically lower in situ pH values, and undersaturation with respect to calcium carbonate. In Georgia, temperatures remain relatively warm throughout the year and therefore macrofau al and microbial activity do not exhibit the extreme seasonal variations present in Connecticut. Because the destruction of reactive organic matter continues throughout the year, the organic matter supplied to the Georgia sediments is less readily metabolizable. As a result, the inception of anoxic-sulfidic conditions is depressed below the sediment-water interface; only limited amounts of ferrous sulfide minerals are formed in the surficial sediments; and saturation or supersaturation with respect to calcium carbonate is maintained throughout the year. This relationship between organic matter metabolizability and calcium carbonate preservation has the potential to be used as an indicator of the environmental conditions present at the time of sediment deposition. Application of the results of this modern sediment study to facies-dependent variations in calcium carbonate preservation in ancient marine shales suggests that prior interpretations of the paleoenvironmental significance of these variations may be in error.

The Carboniferous of Western Europe; the development of a petroleum system

Abstract: A consistent stratigraphic study of the western European Carboniferous Basin has allowed the generation of eight palaeogeographic timeslices. These illustrate a model of large scale eastern (dextral) tectonic escape on the northern side of a convergent margin and integrate the diverse tectonic and sedimentary settings observed within the basin as a whole. This model can be compared to the present day eastern Mediterranean, where a similar range of diverse tectonic settings are observed. Reservoir and source distribution is discussed for each time-slice along with the present distribution of Carboniferous oil and gas fields. Due to the diversity observed no unique play type can be distilled from the data to explain the distribution of hydrocarbons within the studied area.

Nestable hinged container for the display and storage of consumer articles

Abstract: A nestable hinged container for packaging consumer articles. The container includes a receptacle having a base formed with relation to the consumer article, the base terminating in an uppermost edge having an outer periphery, the receptacle further having an upstanding peripheral side wall integral to the outer periphery of the uppermost edge of the base, the peripheral side wall terminating at an upper end thereof in an outwardly projecting peripheral rim flange; and a lid hingedly connected to the receptacle, the lid having an an outwardly projecting peripheral rim flange and an inwardly projecting concave portion located on an upper surface of the lid, the concave portion formed in relation to the base so as to enable nested stacking of a plurality of the containers.

Wireless mobile image messaging

Abstract: Non-verbal communications between users of wireless mobile devices are facilitated using image messages. An image message may e.g. convey information about the sender user, in particular, current information about the sender user. In one aspect, a user may select an image message category, and select an image message among the image messages of the selected image message category for transmission, to quickly, efficiently and graphically convey (current) information about the user. The process may be performed to form a mixed media message. Received image message to convey current information may be aged via time and/or color displays.
