Abstract: The present invention provides methods, systems and computer program products for altering video images including superimposing objects onto the images, particularly addressed to identifying fastener insertion locations onto displayed images of a work pieces. The invention is capable of importing an image of a work piece contained in a computer file, displaying the image, and altering the displayed image and/or superimposing objects onto the image to show the location(s), sequence(s) and/or type(s) of fasteners to be inserted onto the displayed work piece according to operator input and instructions. After each insertion is completed, the display is again altered to show the completion. During use, the system is capable of tracking the fastener installations and updating the video display to show the current status of insertions on the work piece.

Abstract: A pump having a heat exchanger including a rotating baffle sleeve secured to the pump shaft. A seal baffle on the rotating baffle sleeve extends over the pump seal assembly cartridge. A cooling cylinder containing circulating component cooling water is suspended within the rotating baffle sleeve and defines a flow passageway therein for cooling heated product water, before the product water contacts the shaft seal. A seal injector distributor ring uniformly distributes seal injection water to the seal. A thermal shield in the heat exchanger reduces thermal stresses in the heat exchanger. A slotted keyway spacer ring facilitates replacement and alignment of a hydrostatic bearing.
