Abstract: A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.

Abstract: Disclosed is a mill liner for a grinding mill, a mill liner coupling, a coupling tool, and a method of removing a mill liner for a grinding mill. The mill liner is arranged to be removably mounted to an interior surface of the grinding mill. The mill liner includes a coupling component that forms part of a coupling to connect the liner to a coupling tool for lifting of the liner. The coupling component being may be accessible via the inner surface or the wear surface. The coupling component may be in the form of at least one cavity.

Abstract: A method and apparatus for synchronizing viewed information between a first endpoint and a second endpoint of a conferencing environment so that the first and second endpoints display the same location of the viewed information includes one of the endpoints receiving a request to synchronize the viewed information. An identifier of the location to which the document is to be synchronized is also received. The viewed information at the endpoint is then updated to display the identified location. In one embodiment, the first endpoint receives the request to synchronize the viewed information and sends a view synchronization message to the second endpoint. The view synchronization message includes a page identifier corresponding to the identified location and a center point which identifies a location within the page corresponding to the page identifier. Upon receipt of the view synchronization message, the viewed information at the second endpoint is updated to display the identified location.

Abstract: The invention is a filament tensioning device for use on a spool of a type having filament coiled around a cylindrical barrel bounded by flanges at each end of the barrel. The device, constructed in accordance with the present invention, includes a belt or strip of elastic material such as neoprene. The elastic strip is formed into a ring and end portions adjacent the long ends of the strip are bent transverse to the outer surface of the ring forming a radially extending tab. The two end portions are attached and preferably stitched together using two seams, thereby forming a passage therebetween which extends from the strip ends through the length of the tab into the interior of the ring.In use, the filament tensioning device is placed over the barrel of the spool between the flanges and elastically contracts about and circumscribes the coiled filament.
