| 20100269262 | MATTRESS ADAPTED FOR SUPPORTING HEAVY WEIGHT PERSONS - A mattress constructed with multiple foam layers joined together provides reclining support with pressure redistribution for heavy weight persons, particularly those weighing over 350 pounds. The mattress includes: a core layer having a substantially planar top surface and at least two spaced apart regions in a bottom surface from which foam material has been extracted to leave cavities separated by an interconnected network of foam walls, a top layer of viscoelastic foam with an air permeability above 60 ft | 10-28-2010 |
| 20090264549 | VARIABLE FELTED POLYURETHANE FOAMS FOR SPONGES AND WIPES - A polyurethane foam sponge that picks up at least 80% of water in a wipe dry performance test is made by variably felting (compressing under heat and pressure) a foam sheet to a compression ratio of about 1.05 to 2.9. The resulting foam sponge has from 5% to 25% of its top and bottom surface portions modified by the variable felting, while its core portion remains substantially unmodified. | 10-22-2009 |
| 20080213566 | FLAME LAMINABLE HYDROPHILIC ESTER POLYURETHANE FOAMS - A hydrophilic ester polyurethane foam is flame laminated to a substrate using a thin sacrificial layer, preferably a sacrificial foam layer. The sacrificial layer in the resulting laminate structure has a thickness of 1.5 mm or less, and preferably is substantially burnt away. The resulting laminate exhibits good bond strength along its length and width without loss of liquid wicking and absorptive properties. | 09-04-2008 |
