Abstract: A composition for oral, transdermal or subdermal administration to a subject is described. The composition contains: (a) an agonist component; (b) an antagonist component containing at least one antagonist and having a delayed time of release; and (c) an immediate release antagonist removal component, where the subject includes a gastrointestinal tract and the antagonist removal component is present in an amount sufficient to substantially remove the antagonist component from the gastrointestinal tract of the subject before the time of release of the antagonist component. The composition may be delivered to the subject by a method which includes the step of administering the composition orally, transdermally or subdermally to the subject. When the composition of the present invention is administered orally, the method of the present invention may include the step of administering a potassium compound to the subject.

Abstract: The instant invention is directed to large waterborne, towed flexible fluid containment vessels for the transportation of cargo comprising a fluid or fluidisable material and a method of fabricating the vessels. The flexible fluid containment vessel includes an impervious, elongated flexible tubular structure comprised of fabric having a first circumference. The vessel also includes a sealed front end and rear end and a means for filling and emptying the vessel of cargo. The front end or the rear end of the tubular structure is formed by weaving, knitting or braiding in such a manner to have a taper that terminates in a second circumference that is less than the first circumference.

Abstract: A flexible fluid containment vessel fabricated out of fabric for transporting and containing a large volume of fluid, particularly fresh water, having tapered front and/or rear portions formed out of the intermediate tubular structure, including a method of making the same.

Abstract: The invention is directed to a computer implemented system and apparatus for transforming objects in a first data model (source design objects) to objects in a second data model (target design objects) and synchronizing the two data models. The result of the transformation is that at least one of the target design objects is associated with a corresponding source design object. The system associates a unique identifier with each of the target design objects and source design objects, the unique identifier being associated with each map associated with each design object.

Abstract: Apparatus and method for injecting a shot of flowable material into a mold involve moving a plunger-type injector in a continuous non-decelerating manner past an outlet which leads to the mold. The injector is decelerated, but only after it passes the outlet to the mold.

Abstract: An injection blow molding machine construction utilizes pairs of C-shaped cut plate members to support clamps for the injection mold and for the blow mold, respectively. The injection molding frame members are angularly disposed at 60 degrees with respect to the blow molding frame members. The frame members are co-mounted at the ends of the C-shaped members to a pre-stressed central vertically disposed column or post. The respective injection mold and blow mold clamp forces are transmitted to the respective frame members and in turn to the column in a balanced manner to avoid flexure of the plate members. The present construction reduces the bulk of conventional injection blow molding machines, eliminates weldments and provides for ready assembly of the machine and ready access to the molds so as to reduce downtime.

Abstract: An injection molding machine has a high volume cylinder with a piston slidably disposed in the cylinder. The piston is formed with channels and check valves for selective communication from the back of the cylinder to the front of the cylinder. A vertically disposed screw plasticizer provides molten thermoplastic material to the back of the cylinder, which material flows to the front of the cylinder with rearward movement of the piston. When the front of the cylinder is filled with thermoplastic material, the piston is moved forewardly to inject the thermoplastic material into a mold. A reciprocating screw plasticizer first assists in filling the front of the cylinder, and then in completing the injection molding under a high pressure. Novel composite thermoplastic products may be produced.

Abstract: The present invention increases the shot capacity and the screw recovery time of an injection molding machine without increasing hydraulic pump capacity or motor horsepower. In accordance with one aspect of the invention, an existing injection molding machine is retrofitted with two cylinder and piston arrangements which are bolted onto the machine between its plasticizer barrel and its melt manifold. One of the cylinder and piston arrangements is employed to perform a mold-filling operation, whereas the other cylinder and piston arrangement is employed to perform packing and suck back operations.

The apparatus has means for connecting at least one core rod on which the parison is formed to the turntable, such that at least one core rod is parallel to a side face of the turntable, and for rotation therewith.

Abstract: A method and apparatus for blow molding a wide mouth container wherein substantially the entire container is multiaxially oriented in its formation. The method and apparatus produce this container in effectively a one station operation without the need for high pressure injection molding platens. The apparatus is useful in making non-oriented articles as well. One such multiaxially oriented article that may be blow molded is a container having the configuration of an oil can.

Abstract: An end capping machine is disclosed wherein a plastic end cap is formed and bonded to a cardboard sleeve so as to form an integral, wide-mouth container. Each cap is formed and thermoplastically bonded in essentially one-station of a multi-station operation. The machine of the present invention is particularly useful in forming oil cans, and eliminates the need for the conventional metal base and sides.

Abstract: This invention increases the length-to-diameter ratio of plastic articles made on injection molding machines without using long and relatively thin core rods. This added length is obtained by having the first part of the blowing operation stretch the parison lengthwise before there is any substantial displacement of the parison in a radial direction. At the start of the blowing operation, a tube surrounds and confines radial expansion of the parison, but this tube is withdrawn progressively as the blowing operation continues.
