  • Patent number: 8022133
    Abstract: It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.

  • Patent number: 7491762
    Abstract: Compositions comprising hexahydrophthalate (HHPA) metal salts may be useful as nucleating agents in polyolefins. Masterbatch compositions containing such salts and silica and/or hydrotalcite are particularly useful in reducing haze and improving properties of manufactured polyolefin articles or film. Such compositions may be dispersed effectively and efficiently into resin during manufacturing operations in the form of a masterbatch, thereby providing excellent polymer crystallization temperatures, improved polymer physical properties, improved dimensional stability, and improved transparency.

  • Patent number: 7078450
    Abstract: Concentrates (also known as masterbatches) of certain bicyclic dicarboxylate salt thermoplastic nucleating additives in order to facilitate use thereof in typical thermoplastic manufacturing procedures are provided. Such nucleating additives have been found to impart high peak crystallization temperatures to thermoplastics (such as polypropylene, as one example); however, when combined in masterbatch form in the past such a nucleation property was sacrificed due to unforeseen problems associated with polymer-containing concentrates (i.e., pellets, for example) of such additives. Thus, improvements in masterbatching of these bicyclic dicarboxylate salt thermoplastic nucleators has been accomplished to the level necessary to allow for concentrate use with concomitant effective nucleation effects at the same level (if not in excess thereof) of the utilization of such a nucleator added in powder form.

  • Publication number: 20060080500
    Abstract: A method and system for managing the transfer of data from one tape to another. The system uses an operating system to control a plurality of tape drives and a tape manager. The system is configured to enable a user to create a stacked tape, unstack a previously stacked tape, and/or consolidate a previously stacked tape. When a stack is created, data is copied from one or more input tapes to an output tape in any desired format using American National Standards Institute (ANSI) standard labeling conventions. When a user requests that data be unstacked, virtual tape volume (VTVs) on one or more input tapes are located and copied to respective opened output tapes. When data is consolidated, VTVs on one or more input tapes are copied to a single output tape. When data consolidation or stack creation is complete, a directory is written to the output tape.

  • Patent number: 6989154
    Abstract: A specific combination of two different polyolefin clarifying and nucleating agents, namely 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol is provided. Such a combination surprisingly provides improved clarification and crystallization temperatures to polypropylene articles and formulations, better than bis-p-methyldibenzylidene sorbitol alone and equivalent or better than 3,4-dimethyldibenzylidene sorbitol. Such a combination of compounds thus permits the utilization of a new additive for the purpose of modifying polyolefin properties, such as polypropylene clarification and nucleation. The inventive combination may be introduced within any polyolefin composition, again preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive combination of compounds is also provided.

  • Publication number: 20030204639
    Abstract: A method, computing device, operating system and configuration tool for optimizing or at least improving task dispatch in a priority pre-emptive real-time context are disclosed. Tasks making up an operating system are categorized into various classes in accordance with various task attributes, such as need to save floating point context, need to save digital signal processor context and the like. Each class contains only tasks having a unique combination of attributes. An individual subdispatcher function is then generated for each class, the subdispatcher function being adapted to handle tasks within that class with high efficiency. In this way, unnecessary saving and loading of contexts is reduced, and operating efficiency is improved.
