Abstract: Apparatus and methods for providing controlled pressure-flow pulses which purge a catheter system with turbulent flow flushing. Accomplishment of such controlled pressure-flow pulses is provided by a variety of inventive devices including a special plunger rod for a conventional syringe, other interactive parts for conventional syringes, an in-line catheter attachable device which automatically generates the controlled pressure-flow pulses and also single pulse, digitally operated devices.

Abstract: The present invention relates to software enabled wizards that receive input from a user and use the input to generate a customized response. Embodiments of the present invention include design wizards, selection wizards and troubleshooting wizards advantageous for use in commerce, particularly within the chemical industry.

Abstract: Disclosed is a concentrate useful as an additive in a polyester composition comprising a polyolefin and a polyfunctional carboxylic acid or polyol branching agent. Also disclosed is a method of preparing a polyester composition having increased melt viscosity and melt strength, and improved impact strength which comprises the steps ofA) melt compounding a polyolefin and a polyfunctional carboxylic acid or polyol branching agent,B) dry blending the melt compounded mixture formed in A) with a polyester, andC) molding or extruding the dry blended mixture formed into B) to form an article.

Abstract: Disclosed is a process for forming a layered structure of metal sheet and polyester by heating the metal sheet, extrusion coating a thin layer of polyester on at least one side of the metal sheet, passing the coated sheet through nip rolls and optionally quenching the coated sheet to ensure the polyester coating(s) is in an amorphous state.

Abstract: Disclosed are polyester particles adapted to be extrusion blow molded into articles having improved rheological qualities and a process for producing such particles, said particles comprising a polyester having repeat units from about 40 to 100 mol % terephthalic acid, about 80-98 mol % ethylene glycol, about 0.5-10 mol % 1,4-cyclohexanedimethanol, about 3-10 mol % diethylene glycol, and about 0.05-1.

Abstract: Monolayer and multilayer non-oriented polyester films comprising of at least one layer of an amorphous heat-sealing polyester wherein the heat-sealing polyester consisting essentially of terephthalic acid, ethylene glycol, and about 7-15 mol % cyclohexanedimethanol. The heat-sealing polyester has a heat of fusion greater than 0.5 cal/g and is sufficiently crystallizable to allow the drying of mixtures of the heat-sealing polyesters with other crystallizable polyesters without sticking. Multilayered films also contain a layer of an amorphous crystallizable polyethylene terephthalate.
