  • Publication number: 20140250394
    Abstract: Various technologies and techniques are disclosed for providing a table of contents for a document viewer application. A document viewer application is provided that can display a document that has multiple pages of content. Upon receiving a selection from the user to access a table of contents for the document, a table of contents is displayed that contains a representation of at least some of the pages of content in a manner that is overlaid on top of a current position in the document. A navigation feature allows a user to navigate through the table of contents while retaining the current position in the document. A preview size adjustment feature allows the user to adjust a size of the representation of the pages of content for the document.

  • Patent number: 8183319
    Abstract: An aqueous dispersion including a partially fluorinated dispersant, an electrically conductive polymer and a film forming additive. The film forming additive includes a boiling temperature greater than about 85° C. (185° F.). In addition, the concentration of the film forming additive is less than the solubility limit of the additive in water. The dynamic surface tension of the dispersion including the film forming additive is less than about 60 dynes/cm at 100 ms surface age. A method for making an electrically conductive polymer film and devices including electrically conductive polymer film are also disclosed.

  • Publication number: 20100163449
    Abstract: A disposable biodegradable container made of a mixture of biodegradable materials to make a disposable container and a method of manufacturing the same are disclosed. The biodegradable material is produced by mixing chaff, saw dust, straw, pulp or a combination thereof with starch, palm fiber, and melamin resin to produce a mixture; pouring the mixture into a mold; and pressurizing the mixture at high temperature and a high pressure at three times. Accordingly, a disposable container having an excellent hardness, elasticity and compact texture can be manufactured by using the biodegradable materials. Also, it is possible to further enhance physical properties of a disposable container by mixing the mixture with esters, polysorbates, stearyl sodium lactates.

  • Publication number: 20100155994
    Abstract: A method of fabricating a container using a compression molding machine is disclosed comprising supplying raw material into a hopper, which is disposed at one side of the compression molding machine; regulating the supply of the raw material by providing a pair of intercepting screens at the upper and lower portions, so that the intercepting screens can regulate the supply of the raw material by means of a gate cylinder; supplying the raw material to a lower mold so that the raw material introduced from the step of regulating the supply of the raw material is guided into the inside of a molding portion of the lower mold; and, separating and recovering the upper mold for elevating the upper mold from the transported upper and lower molds so that the upper mold can be returned to its initial position.

  • Publication number: 20080320383
    Abstract: Various technologies and techniques are disclosed for displaying content with figures. All figures on a page of content are scaled so that each of the figures fits within a single column. The figures are placed as close as possible to corresponding figure references in text on the page. The page of content is displayed in a format that varies depending upon an output device. Scaled figures can be rendered in an enlarged view. Upon receiving input to select a particular one of the figures, an event handler is invoked that corresponds to the selected figure. The selected figure is displayed in an enlarged version in an enlarged viewing mode.

  • Publication number: 20080295019
    Abstract: An electronic document has a sidebar object that is defined and formatted as an object within the document. The sidebar object may be presented and operate as a separate document within the main document, with individual controls such as scrolling, pagination, and zoom. A display mechanism determines display parameters for a display device and applies formatting to the document as a whole, including the sidebar object, to present the document. The sidebar object may have a second format that is applied to the sidebar object.

  • Patent number: 4764646
    Abstract: In a distributor cap for internal combustion engines, a multi-positionable contact which can be manually rotated to successively present each of a plurality of contact surfaces to the distributor arm after an adjacent contact surface has become pitted, corroded or otherwise worn; thus increasing the useful life of the distributor cap. The contact surfaces are symmetrically arranged about the axis of rotation of the contact. Rotation can be achieved by means of a screwdriver blade introduced through the sparkplug wire terminal to act on a slotted head of the rotating contact exposed at the bottom of the sparkplug wire terminal, or by grasping the contact from underneath.
