Abstract: The present invention relates to a method for forming the spacer of slitting machine. Firstly, the material is provided, then various processing methods are applied to form the spacer with smooth surface and a plurality of fixed-distance columns. Compared to the conventional spacer, the weight of lightweight spacer of the invention is reduced by 50%±10%. Additionally, the lightweight spacer of the invention not only is placed on the other positions of slitting machine, but also is suitable for the machines of other relevant fields.

Abstract: One aspect of this disclosure relates to presenting a user with a stimulus to elicit user interaction with a task on a computing platform associated with the user. The stimulus may be presented on the computing platform when a set of triggering criteria is satisfied. The stimulus includes a task for the user to complete. The stimulus prompts the user to complete the task. The task includes a set of task criteria for completion. Responsive to the user satisfying the set of task criteria, the user is presented with one or more options to modify the stimulus. The user may be continuously prompted by the stimulus until the set of task criteria is satisfied.

Abstract: A method to fabricate and assemble metal doors and panels, or similar structures, is taught. Under the present invention, profiled edges of two or more skins forming the sides of the door or panel are moved together. The skins are only locked together when a locking bar or wedge is applied to the channels formed by the profiled edges. Under the present invention, less effort is required to assemble such metal doors and panels as the contact between the profiled edges of the skins is not tight. This allows the skins to be easily moved together or repositioned.

Abstract: A wooden door with panel ribs (2.10, 2.12, 2.14) in the hollow core of the door wherein the ribs are made from scrap wood pieces. Since the scrap wood pieces are usually too short for this purpose, a method is also described that teaches means to connect the ribs made from the scrap wood pieces into useful lengths by the use of notches, connector blocks and conventional fasteners.
