...that the inventor of the electric motor was a blacksmith named Thomas Davenport? Described as "a brilliantly unsuccessful inventor", Davenport invented the first rotary electric motor. In 1836 he headed out -- on foot -- from his Vermont home to file a patent application at the Patent Office in Washington, D.C. By the time he got there, he had squandered away his money and couldn't afford the $30 filing fee so he turned around and went home. When he later mailed in his application with money he'd raised, the Patent office was destroyed in a fire. He did finally get credit for his invention on Feb. 5, 1837.

AbstractA method and system in a document viewer for scrolling a substantially exact increment in a document, such as one page, regardless of whether the zoom is such that some, all or one page is currently being viewed. In one implementation, pressing a Page Down or Page Up keyboard key/button allows a user to begin at any starting vertical location within a page, and navigate to that same location on the next or previous page. For example, if a user is viewing a page starting in a viewing area from the middle of that page and ending at the bottom, a Page Down command will cause the next page to be shown in the viewing area starting at the middle of the next page and ending at the bottom of the next page. Similar behavior occurs when there is more than one column of pages being displayed in a row. | InventorsAssigneeApplicationNo. 11073189 filed on 03/04/2005US Classes:715/784, Window scrolling715/785, Autoscroll715/786Scroll tool (e.g., scroll bar)Field of Search715/500, PRESENTATION PROCESSING OF DOCUMENT715/517, Layout715/525, Pagination715/526, Display processing715/784, Window scrolling715/785, Autoscroll715/786Scroll tool (e.g., scroll bar)ExaminersPrimary: Campbell, Joshua DAttorney, Agent or FirmUS Patent References5463725, Data processing system graphical user interface which emulates printed materialIssued on: 10/31/1995 Inventor: Henckel, et al.5764227, Document display apparatus for displaying document containing a plurality of pages.
