    • Methods and systems consistent with the present invention provide a Supernet, a private network constructed out of components from a public-network infrastructure. Supernet nodes can be located on virtually any device in the public network (e.g., the Internet), and both their communication and utilization of resources occur in a secure manner. As a result, the users of a Supernet benefit from their network infrastructure being maintained for them as part of the public-network infrastructure, while the level of security they receive is similar to that of a private network. The Supernet has an access control component and a key management component which are decoupled. The access control component implements an access control policy that determines which users are authorized to use the network, and the key management component implements the network's key management policies, which indicate when keys are generated and what encryption algorithm is used. Both access control and key management are separately configurable. Thus, the Supernet provides great flexibility by allowing different key management policies to be used with the same access control component.
    • 与本发明一致的方法和系统提供了一种Supernet,一种由公共网络基础设施的组件构成的私有网络。 超网络节点可以位于公共网络(例如,因特网)中的几乎任何设备上,并且资源的通信和利用都以安全的方式发生。 因此,Supernet的用户受益于其网络基础架构,作为公共网络基础架构的一部分,而其接收的安全级别与私有网络的安全级别相似。 Supernet具有访问控制组件和分离的密钥管理组件。 访问控制组件实现访问控制策略,其确定哪些用户被授权使用网络,并且密钥管理组件实现网络的密钥管理策略,其指示生成密钥以及使用什么加密算法。 访问控制和密钥管理都可以单独配置。 因此,通过允许不同的密钥管理策略与相同的访问控制组件一起使用,Supernet提供了极大的灵活性。

    • Mold press apparatus for use in the manufacture of molded articles, particularly starch-bound containers and other articles. The mold press apparatus includes a planar array of female mold halves and a corresponding planar array of male mold halves. The planar array of mold halves remain substantially coplanar throughout the process of selectively mating and separating the male and female mold halves. When used to manufacture molded articles from aqueous starch-based compositions, the molds are equipped with venting means, such as vent holes and/or a vent gap, which allow for the escape of water vapor from the mold cavities defined by the mated male/female mold pairs. A suction removal system may be used to remove the molded articles from the mold press apparatus, typically from the female mold halves. The demolded articles are deposited on a conveyor system equipped with individual nests for each article.
    • 用于制造模制品,特别是淀粉结合容器和其它制品的模压机。 模压设备包括阴半模的平面阵列和相应的阳半模的平面阵列。 半模的平面阵列在选择性地配合和分离阳模半模和阴半模的整个过程中保持基本共面。 当用于由水性淀粉基组合物制造模塑制品时,模具配备有通气装置,例如通气孔和/或排气间隙,其允许水蒸汽从由配合的阳/ 女模对。 可以使用抽吸移除系统来从模压机装置(通常从阴模半部分)去除模制品。 脱模的物品被放置在配备有每个物品的单独巢的输送系统上。
