  • Patent number: 6640250
    Abstract: Disclosed is an apparatus and method for selecting wide area network resources, such as resources identified by URL values, using a rotary knob for user input. A client device having a display and a rotary knob is used for accessing network resources via a public network using an application program, such as a browser application. Rotation of the knob is detected by the client device, which adjusts the contents of a previewing window according to the rotation of the knob. The previewing window identifies graphics corresponding to predefined network resources and the graphics are output in a preview area of the display on the client device. As the user rotates the knob, the graphics for the network resources in the preview window are scrolled through the preview area of the display under control of the knob. The preview area includes a selection frame for selecting a network resource.

  • Patent number: 5236643
    Abstract: The invention relates to a process for preparing gas separation membranes or modules. Membrane forming material is cast into a wet membrane which is wound into a spiral module. The spiral module is arranged in a closed circulating apparatus. Exchanging solvents or treating solutions are circulated through the circulating apparatus and the spiral module for an appropriate period of time. The module and circulating apparatus are purged until the membrane is dry, thus producing a gas separation membrane or module.
