  • Patent number: 11096835
    Abstract: The present disclosure relates to methods for sealing absorbent cores of disposable diaper pants during the assembly process. The diaper pants may include a chassis connected with a ring-like elastic belt. Aspects of the assembly methods involve bonding a continuous length of absorbent cores between a continuous topsheet substrate and a continuous backsheet substrate advancing in a machine direction. The combined continuous topsheet substrate, continuous backsheet substrate, and continuous length of absorbent cores are then cut along a cross direction to create discrete chassis, wherein the topsheet, the backsheet, and the absorbent core of each chassis have equal longitudinal lengths. The discrete chassis are then deposited onto a first continuous elastic laminate and a second continuous elastic laminate. Opposing end regions of the absorbent cores may then be sealed by positioning a sealing layer across the topsheets of the chassis.

  • Patent number: 11046005
    Abstract: Additive manufacturing or 3D printing produces considerable quantities of waste ink or resin during the course of additive manufacture. The waste ink is a hazardous substance and must be collected and disposed of accordingly. The present embodiments provide a waste ink collection device that collects the waste ink from the printing process, or from head cleaning and other incidental operations, stores the waste and cures it. The waste ink is thus rendered safe for conventional disposal. A waste ink disposal cartridge collects the waste ink and carries out curing.

    Abstract: The invention relates to a method for producing a biaxially oriented polypropylene film including at least one layer, which is constructed from propylene polymer B and a propylene polymer that has been recycled once. The method includes heat and melting propylene polymer B in a first extruder and heating a melting a propylene polymer A without a fraction of recycled material in a second extruder. The molten mass of the propylene polymer A is fed to two sides of the propylene polymer molten mass of B such that the propylene polymer A forms border regions of the film during the production process. The two border regions are then cut off after longitudinal and traverse stretching of the film, and melted and mixed together with the propylene polymer B and extruded to form a precursor film in the first extruder. The biaxially oriented polypropylene film comprising a propylene polymer that has been recycled only once is useful for producing capacitors.

    Abstract: Polyester compositions described herein have properties which are particularly suitable for extrusion blow molding (EBM). These properties relate primarily to the rate of crystallization and melt strength or melt viscosity. Articles prepared from the polyester compositions exhibit good clarity, aesthetics, and other physical properties. The polyester compositions also exhibit broad molecular weight distribution (MWD), resulting in improved processability and melt strength. The crystallization rate allows for good drying characteristics while also enabling the use of regrind. In addition, the compositions exhibit improved recyclability, such as in existing PET recycling streams. In one aspect, articles are prepared in an extrusion blow molding method by combining a dry first polyester copolymer component, a dry second polyester component, and a chain extender to form a feed material suitable for extrusion blow molding.

The components of the immiscible blend which have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enables the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.

  • Patent number: 8080191
    Abstract: A polymer blend has a base and blend components. The base and blend components could be a branched slow crystallizing PET and a faster crystallizing PET, respectively. The ratio of base and blend components result in a block copolymer, the melt processing time and branching or chain extender levels can be can be tailored to impart the polymer blend with sufficient melt strength and crystallization rates, such that it is slow enough during the blow molding process to produce a clear article and yet fast enough during the subsequent PET recycling process making it suitable for extrusion processes as well as for recycling. The combination of materials can be used to form monolayer or multilayer articles.

    Abstract: Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze, and comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.

  • Publication number: 20110121475
    Abstract: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed.
