Title: Cutting chain grinder and method of grinding
Inventor: HAILE DANIEL
IPC: B23D63/16
Filed: 2005-02-22
Abstract: A cutting chain bench grinder includes a self-centering vise that centers the cutting chain on an axis of rotation of the vise base. By centering the cutting chain to intersect the vise base axis of rotation, consistent top plate lengths and hook angles can be ground into left and right-hand cutters on a cutting chain. The vise base may also be adjusted horizontally in and out from the grinder base to align the vise base axis of rotation with the axis of rotation of the grinding wheel. The vise base may also be adjusted vertically relative to the vise base to vertically compensate for grinding wheel wear and to control grinding depth. A light tension spring may be used to bias the grinding head in both grinding and dressing positions. A down angle positioner may also be provided that rotates the cutting chain in the vise around a longitudinal centerline of the cutting chain.

Title: Hopper car side construction and method
Inventor: FORBES JAMES W
IPC: B61D17/08
Filed: 2006-12-01
Abstract: A hopper car has arcuate side sheets that are bent over the forming members of the structure to give a generally outwardly bulging shape. The upper margin of the side sheet is kinked inwardly of the radius of curvature of the larger portion of the side sheet more generally, such as may tend to impose a bending moment on the large, relatively thin side sheet panels. This may in turn tend to urge or bias those panels to a bulging position or shape, rather than a sagging, deflected, or inwardly dented position.

Patent CA-2578157-A1 (CA)
Inventor: LIN JIE
IPC: G06F17/30
Filed: 2005-08-23
Abstract: Many companies provide online search facilities that enable users to conduct computerized searches for documents. Unfortunately, these searches frequently provide results that include duplicate documents---that is, documents that are completely or substantially identical to each other. This problem is particularly vexing when searching news stories, for example. Moreover, the duplicate documents are intermixed in the search results, leaving users to manually manage the complexities of identifying and/or filtering them.  Accordingly, the present inventors devised systems, methods, and software that facilitate the identification and/or grouping of duplicate documents in search results. One exemplary system includes a signature generation module which generates document signatures based on length, temporal, and/or content components; a real-time duplicate detection module which uses the document signatures to identify "exact" or "fuzzy" duplicate documents; and a user-interface or presentation module which controls how duplicate documents are presented or suppressed in search results.
