    Abstract: A CARPET IS FORMED BY ADHERING A SECONDARY BACKING TO A PRIMARY BACKING WITH A THIXOTROPIC POLYURETHANE COMPOSITION SO THAT THERE IS SUBSTANTIALLY COMPLETE SATURATION OF THE BUNDLE WRAP WITH THE COMPOSITION WITHOUT PERNETRATION THROUGH THE PRIMARY BACKING. THE COMPOSITION CONTAINS WATER, A POLYOL WITH A HYDROXYL NUMBER LESS THAN 100, A DIISOCYANATE, A FILLER AND A CATALYST AND HAS AN INITIAL VISCOSITY OF BETWEEN 30,000 AND 1008000 CPS. #7 SPINDLE BROOKFIELD RVF, A POT LIFE OF BETWEEN 10 AND 60 SECONDS AND IS EXPANDABLE BETWEEN 100 AND 400 WHEN COMPLETELY REACTED. IT IS APPLIED TO THE UNDERSIDE OF THE PRIMARY BACKING WITH A DOCTOR KNIFE AND HEATED. A SECONDARY BACKING IS APPLIED TO THE UNCURED COMPOSITION AFTER IT IS SPREAD ON THE PRIMARY BACKING AND THE RESULTANT LAMINATE IS SUBJECTED TO PRESSURE PRIOR TO CURING TO DISINTEGRATE SUBSTANTIALLY ALL OF THE CELLS IN THE POLYURETHANE.

    Abstract: A system and associated method include coconut fiber liners used in hanging wire flower baskets. The coco fiber basket liner may create a water seal in the liner by over-coating a portion of the inner liner with a unique blend of all-natural rubber latex, then molding the liners into shape. The added latex coating may seal in and hold water in the bottom portion of the liner. This feature may keep the soil moist while still allowing air to flow thru the plants. The moisture and airflow may help promote healthier plants and roots and require less watering. Excess water beyond the intended amount may drain out thru the permeable side walls of the coco liner.

    Abstract: A manufactured hemp product comprising a plurality of adhesively bonded and pressed hemp strands where the majority of the hemp strands are of generally the same length and comprise a naturally-occurring, generally elongate internal structure extending generally along one axis of the strand that has been at least partially laterally broken and at least permeated by an adhesive. The hemp strands are oriented roughly parallel to one another along their length. The manufactured hemp product comprises an amount of adhesive between about 5% to about 49% by weight. The manufactured hemp product can be used as a wood substitute in terms of appearance and performance. The manufactured hemp products may have aesthetic and structural qualities that are suitable for high traffic, high visibility applications such as boards, blocks, beams, panels, flooring, furniture, building materials and other wood products.
