Abstract: The present invention relates to novel multi-layer coextruded thermoplastic stretch wrap films useful for the packaging or palletizing of goods. More particularly the films of this invention comprise at least three layers having two outer layers and at least one intermediate layer placed between the outer layers. The intermediate layer is formed from a high pressure low density polyethylene resin and the outer layers are formed from a linear low density polyethylene copolymer such as ethylene copolymerized with a minor amount of at least one C.sub.4 to C.sub.10 alpha-olefin, such as hexane-1, octene-1, decene-1, 4-methyl-pentene-1 and butene-1. The force required to stretch the novel films of this invention may be controlled by the thickness of the intermediate layer relative to overall film thickness, the melt index of the intermediate layer resin, the molecular weight of the intermediate layer resin or a combination thereof.

Abstract: Thin filmed thermoplastic material wall coverings having a preprinted image thereon and provided with a static electrical charge for securing the coverings to a surface. The wall covering may comprise posters, maps, and the like, and the image is printed on the film by means such as silk-screening. The static electrical charge is sufficient to removably secure the film to a wall surface, a window, or the like, and allows for relocation of the covering without damage to the surface upon which it is secured. The coverings may be packaged individually, or be dispensed from a continuous roll. Preprinted maps adherable to a window surface such as a windshield of an automobile are provided.

Abstract: A process and apparatus for forming a hole within an unconsolidated hydrocarbonaceous fluid-bearing formation, installing a slotted liner and gravel packing the liner in a single trip into the formation. The apparatus includes a drill bit for drilling a pilot hole; a housing mounted above the pilot hole drill bit; means for enlarging a pilot hole, the pilot hole -enlarging means pivotally mounted within the housing and capable of pivoting between a retracted position and an expanded position for enlarging a pilot hole to a diameter larger than the pilot hole and sufficient for gravel packing; a slotted liner having a first end and a second end, the first end joined to the apparatus above the housing; and a drive assembly joined to the second end of the slotted liner.

Abstract: A material extraction nozzle for separating a mixture of materials having different densities, comprising: a nozzle body shell having an outer surface with a tangentially located material inlet at an upper portion thereof and an inner surface defining in part a frustrum of a cone; a substantially conical diffuser section having an outer surface terminating in an apex, the diffuser section axially aligned within the nozzle body shell in a spaced relation therewith so as to form an extraction chamber with the inner surface of the nozzle body shell and the outer surface of the substantially conical diffuser section; an extracted material outlet port positioned axially through the substantially conical diffuser section; and at least one rejected material capillary outlet located below the apex of the diffuser section.

Abstract: An aqueous polymeric gel-forming composition capable of selectively plugging highly permeable zones in subterranean oil-bearing formations. The composition comprises an aqueous solution of an anionic acrylamide copolymer of high molecular weight, comprising about 5 to 95 weight percent of 2-acrylamido-2-methylpropanesulfonic acid, about 2 to 95 weight percent of N-vinyl-N-methyl acetamide and about 5 to 93 weight percent of acrylamide, and a crosslinking agent selected from the group consisting of transition metal ions, phenolic resins and amino resins. The compositions of this invention will form stable gels in brines of wide-ranging salinity and are effective at the pH levels encountered in carbon dioxide and water flooding operations. Also provided is a process for selectively plugging regions of higher permeability within an oil-bearing formation to improve sweep efficiency during a fluid flood oil recovery operation.

Abstract: An apparatus for automatically stacking molded articles successively trimmed by a trim press from a web of thermoplastic material, the trim press having a stationary die member which includes a die plate and a die shoe, the apparatus comprising: (a) a frame; (b) a carriage mounted to the frame; (c) at least one stacking mechanism, the stacking mechanism comprising: (i) a plurality of stack rods rotatively mounted to the carriage each of the stack rods having a stack dog located substantially perpendicular to a first end thereof the stack dog positionable within a corresponding aperture of the die shoe of the stationary die member; and (ii) mechanism for rotating the stack rods so that the stack dog engages an endmost article of a completed stack of articles, the stack of articles located at least partially within the die shoe of the stationary die member; and (d) mechanism for transporting the completed stack of articles from within the die shoe of the stationary die member to a position for removal from the

Abstract: A food storage container for dry or liquid foods and other open air perishable products provides a leak-resistant seal when the lid is in a closed position and easy pouring of contents when in the open position. The container is easy to open, employing rocker points to allow for a rocking acting effective to release the lid from a closed position when a downward force is exerted upon an upper surface of the lid thereby providing an effective opening for pouring. A leak-resistant seal is achieved through the use of a plug section of the lid having a continuous outer peripheral surface which effects a close conforming fit with a similarly positioned surface area on the container body in a continuous and positive manner.

Abstract: An opaque, biaxially oriented polymeric film structure, produced by orienting the film to a degree which provides low light transmission and improved machinability.

Abstract: Non-carcinogenic bright stock extracts and/or deasphalted oils are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the bright stock extract or deasphalted oil and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic bright stock extracts and/or deasphalted oils are then processed utilizing the conditions so established. A bright stock extract and a deasphalted oil substantially free from mutagenic activity, as well as processes for their production are also provided herein.
