Abstract: A universal traction device for movement over even and uneven supporting surfaces that includes an all-terrain wheel having a circular wheel assembly with a plurality of spoke-containing components arrayed around an outer perimeter wheel edge and control means for extending spokes from the spoke-containing units when encountering an obstacle that the vehicle is to traverse and retracting the spokes when the spokes are no longer required for traversing the obstacle.

Abstract: A high speed apparatus and method for reorienting and assembling individual ones of flat articles, such as envelopes, into horizontal rows of articles which are vertically oriented, on edge, and stacked in facing relation. Envelopes are delivered horizontally and seriatim, to an article rotation assembly. The rotation assembly reorients the envelopes into a vertical, on-edge orientation, and feeds them individually to a helical drive assembly. The drive assembly includes a pair of parallel, counter-rotating, helical screws, mounted on a pivotally suspended sub-frame. The screws transport the envelopes in spaced relation to an accumulating conveyor. The conveyor has movable brace plate, transversely positioned over a pair of conveyor belts. A roller on one end of the plate rests upon one of the belts. Successive envelopes are delivered to and stacked against the brace plate. As the pressure increases, the sub-frame pivots away from the plate until a predetermined limit is reached.

Abstract: An apparatus and a method for detecting indicia on articles. The indicia act to identify a group of articles, having a common characteristic. The articles may be address panels used in mass mailings. Particular address panels, representing the beginning or end of a zip code or a postal delivery route, are pre-marked with one or more special indicia. The apparatus includes a scanning station, a computerized system controller, and a marking station. The scanning station includes a video camera, a video analyzer, a camera controller, and a video monitor. The video camera is programmable by using the camera controller and the video monitor, to scan only a predetermined operative scanning area of each article. The video analyzer assess each pixel within the scanning area and adds up the total number of pixels having a desired characteristic. If the pixel count satisfies predetermined criteria correlating to the presence of an indicia, the article is electronically tagged by the system controller.

Abstract: A method of producing at least one control signal data look-up table for a mail insertion machine having a 360 degree cycle of operation and capable of variable operating speeds within a given cycle. The mail insertion machine possesses predetermined electro-mechanical lag times for extending and retracting mechanical components. The method entails creating a baseline control signal data look-up table for a first operating speed based upon pre-determined electro-mechanical lag times. The look-up table comprises a start angle and a stop angle within the 360 degree cycle of operation. The start and stop angles are then compensated for a second operating speed based upon the pre-determined electro-mechanical lag times for extending and retracting mechanical components and the first operating speed. A second control signal data look-up table is then created by writing the compensated start and stop angles that correspond to the second operating speed into the second control signal data look-up table.
