  • Patent number: 11297964
    Abstract: A temporary roll-up floor cover includes a rugged upper layer that is impervious to water and pervious water vapor, and a lower antimicrobial wicking layer that quickly spreads water while transmitting water vapor, to facilitate evaporation of moisture that gets under the cover. The cover may also include one or more of a central layer containing a microporous membrane, a coating or film layer which may be perforated, and a stiffener lattice that resists folding, gathering and puckering without preventing the cover from rolling up. The coating layer adds additional resistance to folding, gathering and puckering without preventing the cover from rolling up. The coating may be perforated to increase water vapor transmission through the cover. One or more antimicrobial agents may be incorporated into the floor cover, for example, into the wicking layer during extrusion of the airlaid mat forming the wicking layer.

  • Patent number: 11058109
    Abstract: Pest-repellent pallet slip sheets for preventing or reducing rodent or pest damage to goods placed on pallets or other locations. The pest-repellent pallet slip sheets generally include slip sheets designed for placement on the top portion of a pallet, such that the slip sheet covers substantially the entire pallet. The slip sheets may be treated with repellent substance all over, randomly, or in a pattern such that a specific portion, or all, of the slip sheet is treated with the pest-repellent substance. The pattern may be produced, for example, by feeding slip sheet material past an application device at a given rate of speed, and then intermittently interrupting the application of the pest-repellent substance if an intermittent pattern is desired. A colored dye may be added to the pest-repellent substance to create a visible indication of a pattern or treated area.

  • Patent number: 11035137
    Abstract: A dual-purpose concrete cover that includes a construction cover layer, a vapor retardant layer, and a wicking layer. An anti-snag scrim layer may be included under the wicking layer. One or more antimicrobial agents may be included in the wicking layer or other locations within the cover to prevent mold, mildew, bacterial and viral growth. While conventional concrete curing blankets often include a vapor barrier selected to keep the concrete surface wet well past the concrete curing period, the vapor retardant layer is designed to allow the dual-use cover to dry out at about the end of the concrete curing period so that the dual-use cover can remain in place as a construction cover after the curing period. The dual-purpose concrete cover is designed to fully dry prior to removal, which allows it to be reused, whereas conventional concrete curing blankets are typically discarded after a single use.
