Abstract: The present invention provides an apparatus and methods for connecting an attachment to a hitch system of a vehicle. The apparatus comprises means for connecting the apparatus to a hitch system and means for connecting the apparatus to an attachment, such as a plow or scraper. The present invention allows the attachment to be extended behind, offset to, or pivoted relative to the vehicle. In addition, the present invention allows multiple attachments to be connected to a vehicle by way of its hitch system.

Abstract: Apparatus and methods are disclosed for spraying an adhesive in a selected pattern on a continuously moving web. The method includes the steps of: (a) supplying a predetermined volumetric flow of adhesive to a nozzle; (b) selectively operating the nozzle between an off position and an on position to spray the volumetric flow of the adhesive; (c) diverting the volumetric flow of the adhesive from the nozzle when the nozzle is operated in the off position; and (d) maintaining a back pressure at the nozzle when the nozzle is operated in the off position to provide a substantially instantaneous spray of the adhesive when the nozzle is operated from the off position to the on position.

Abstract: A fire protective cover for protecting from warehouse fires non-metallic liquid holding containers supported by a steel cage is provided. The cover has a heat insulating layer and a heat reflective layer adjacent the heat insulating layer on the side opposite the steel support cage. The cover drapes over the top and sides of the steel cage, creating a space between the cover and the container. The cover mitigates the possibility that the container will melt during a warehouse fire by reducing the heat transfer from the fire to the steel cage and by creating an oxygen depleted zone between the cover and the container.
