    • A molding composition is provided that includes a thermoset cross-linkable polymeric resin, a fibrous filler and a thickener system. The thickener system includes an amine and an isocyanate that are reactive to form a polyurea. The polyurea is operative to thicken the molding composition formulation prior to polymeric resin thermoset with superior properties relative to conventional thickener systems. A molded article produced from a cross-linked thermoset polymeric resin containing fibrous filler and a polyurea present from 0.05 to 15 total weight percent of the article either forms an interpenetrating network between the resin and the polyurea or the resin and polyurea crosslink upon resin thermoset to further strengthen the resulting article. A process for thickening a molding compound includes adding a quantity of an isocyanate having an isocyanate group equivalent number and a quantity of an amine having an amine equivalent group number such that the isocyanate equivalent group number:amine equivalent group number ratio is between 10:1 and 1:10 to a molding composition formulation that contains a thermoset cross-linkable polymeric resin and a fibrous filler. A period of time is provided to allow the amine and isocyanate to react to form a polyurea prior to cross-linking of the thermoset cross-linkable resin.
    • 提供了一种模制组合物,其包括热固性交联聚合物树脂,纤维填料和增稠剂体系。 增稠剂体系包括胺和异氰酸酯,其可形成聚脲反应。 在聚合树脂热固性材料之前,聚脲可以使模制组合物配方变厚,相对于常规的增稠剂体系具有优异的性能。 由含有纤维填料的交联的热固性聚合物树脂制成的模制品和存在于该制品的总重量的0.05至15%的聚脲在树脂与聚脲或树脂之间形成互穿网络,并且在树脂热固化时交联聚脲 进一步加强所产生的文章。 增塑模塑料的方法包括加入一定量的具有异氰酸酯基当量数的异氰酸酯和一定量的具有胺当量数的胺,使得异氰酸酯当量数:胺当量数比为10:1 和1:10至含有热固性交联聚合物树脂和纤维填料的模塑组合物制剂。 提供一段时间以允许胺和异氰酸酯在热固性交联树脂交联之前反应形成聚脲。

    • A data storage management and scheduling system schedules the recording, storing, and deleting of television and Web page program material on a client system storage medium. The invention accepts as input a prioritized list of program viewing preferences which is compared with a database of program guide objects which indicate when programs of interest are actually broadcast. A schedule of time versus available storage space is generated that is optimal for the viewer's explicit or derived preferred programs. The preferred programs include television broadcast programs and Universal Resource Locators (URLs). The viewer may request that certain programs be captured, which results in the highest possible priority for those programs, or express preferences using appurtenances provided through the viewer interface. Preferences may additionally be inferred from viewing patterns. The invention correlates an input schedule that tracks the free and occupied time slots for each input source with a space schedule that tracks all currently recorded programs and the programs that have been scheduled to be recorded in the future, to schedule new programs to record and resolve recording conflicts. A program is recorded if at all times between when the recording would be initiated and when it expires, sufficient space is available to hold it. All scheduling conflicts are resolved as early as possible. A background scheduler schedules each preferred program in turn until the list of preferred programs is exhausted or no further opportunity to record is available.
    • 数据存储管理和调度系统在客户端系统存储介质上安排电视和网页节目素材的记录,存储和删除。 本发明接受与节目指南对象的数据库进行比较的节目观看偏好的优先级列表作为输入,该节目指南对象指示感兴趣节目何时实际上被广播。 生成时间与可用存储空间的时间表,对于观看者的显式或派生的优选程序是最佳的。 首选节目包括电视广播节目和通用资源定位符(URL)。 观众可以要求捕获某些节目,这导致那些节目的最高可能的优先级,或使用通过观看者界面提供的附件来表达偏好。 可以从观看模式另外推断偏好。 本发明将输入日程表相关联,以便跟踪每个输入源的空闲时间和空闲时间表,跟踪所有当前记录的节目和将要安排的节目,以安排新的节目来记录和解析 记录冲突。 如果在录音开始之间的任何时间和到期日期之间的任何时候都记录有一个程序,就有足够的空间来保存它。 所有调度冲突都尽早解决。 后台调度器依次调度每个首选程序,直到首选程序列表用完或者没有更多的记录机会可用。
