  • Patent number: 6735883
    Abstract: Apparatus and a method for enhancing the effectiveness of a water spray (30) to cool and/or remoisten a web (12) of material. The apparatus includes a web dryer, preferably a flotation dryer (100), an electrostatic charge generating device (31) or devices, a water spray (30), an integrated power supply (20) to supply high voltage power to the charge device, and a drainage system (35) for handling excess liquid generated during the cooling and/or remoistening of the web. The cooling apparatus is capable of a modular arrangement to optimize spacing and facilitate the addition of cooling capacity where needed, such as with faster web speeds or heavier web weights. One or more temperature sensors can be used to optimize the amount of and rate of fluid fed to the spray nozzles. The spray nozzles and charge bars can be retractable with respect to the web to facilitate web-up procedures.

  • Publication number: 20020128940
    Abstract: Methods and systems for electronically representing records of obligations are provided. The records are stored such that content describing an obligation from an obligor to an obligee is unalterable, identifiable as current and authentic, and non-repudiable. Transfers of ownership of the obligation may also be controlled and recorded using the electronic records. An obligation may not be recorded as being transferred without the consent of the of the current owner of the obligation. Security interests in obligations may also be recorded. The secured party may be able to control transfer of ownership of the obligations and modification of the electronic records. In preferred embodiments, these features may be achieved by using various digital signature and encryption techniques.

  • Patent number: 6408754
    Abstract: A flexographic printing apparatus for printing a moving web is provided with a rotatable ink roller, a roller support that rotatably supports the ink roller, an ink source associated with the ink roller which provides ink for the ink roller, a rotatable printing roller associated with the ink roller, and a printing plate disposed on the printing roller that makes physical contact with the ink roller so that ink is transferred from the ink roller to the printing plate as the ink roller and the printing roller rotate. The printing apparatus also has a rotatable backing roller disposed adjacent the printing roller so that the moving web on which ink is to be applied passes between the backing roller and the printing plate as the backing roller and the printing roller rotate so that a printed image is applied to the web. The apparatus also has a charge applicator that causes an electric charge to be applied to the semi-conductive printing plate.

  • Patent number: 5402616
    Abstract: A metal weldment and method of manufacturing the same in which the metal weldment is embedded in a concrete slab-type structural member. The weldment has a central plate having a planar, weldable surface along an edge of the concrete slab, the weldable surface is perpendicularly disposed to the horizontal plane of the concrete slab. There are a pair of outstanding arms extending from the weldable surface and which are embedded in the concrete slab. The outstanding arms have a constant height across their length and support a steel reinforcing mesh at a predetermined height during the concrete slab casting operation. A blockout is provided to the mold during the casting operation to keep the top edge and front surface of the weldable surface free and clear of concrete. This provides for thermal expansion of the weldable surface and minimizes cracking and spalling of the concrete during welding. The blockout is removed from the mold after the concrete has hardened and can be re-used.

  • Patent number: 4425719
    Abstract: An assembly of air bars from which air is blown against a lengthwise moving web to contactlessly confine it to a plane comprises a header having a ported wall extending along its full length, parallel to said plane. Each of a series of outlet ports along the ported wall opens into an air bar intermediate its ends. A centrifugal blower has its cylindrical rotor near a rear end of the header, spaced to the side of said ported wall remote from the plane. An internal plenum chamber in the header opens to the outlet ports in the rear one-third to one-half of the header. The blower has one outlet near the rotor periphery from which air flows into the front part of the header and another outlet, spaced at a greater distance from the rotor periphery, from which air flows into said plenum chamber. The header is movable toward and from said plane relative to the blower, for air bar retraction to facilitate web threading.
