  • Patent number: 10245346
    Abstract: Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.

  • Patent number: 8951634
    Abstract: The present invention relates to a filler material for a floor, comprising a natural base material and a mixture containing loess and a resin in powder or pellet form, as well as to a method for producing the filler material. The filler material of the present invention uses the natural base material and is thus environmentally-friendly and not harmful to the human body. Further, in the event rice husks are used as the natural base material, a person slipping on the floor is protected from burning caused by friction as the rice husks have a high moisture content. In addition, the loess contained in the filler material keeps the floor from becoming moldy and emits far infrared radiation, and therefore is beneficial to the human body. The resin emulsion of the filler material prevents the natural base material from generating dust, thus preventing dust from entering the human body via the respiratory organs of the human body.

  • Patent number: 8852736
    Abstract: A method of forming a reconstituted wood block can include providing a recovered wood having a high aspect ratio along wood grains of the recovered wood. The recovered wood can be radially crushed or obtained as strips of recovered veneer. The recovered wood can be pretreated to increase resin absorption to form a degreased wood. The degreased wood can then be dried sufficient to reduce a moisture content to produce a dried wood. The dried wood can be soaked in a resin solution to form a resin impregnated wood. The resin impregnated wood can be dried to reduce the moisture content without substantially curing the resin to form a dried resin impregnated wood. The dried resin impregnated wood can then be molded having wood fibers oriented in a non-random predetermined pattern substantially common direction and compacted to form an uncured molded wood. The pattern can be oriented along a substantially common direction or portions may be oriented transverse to others to obtain a knotted appearance.

  • Patent number: 8298646
    Abstract: A composite article includes a matrix having first and second opposing surfaces defining a transverse dimension and a filler material embedded in the matrix. The filler material presents a density gradient in the transverse dimension wherein a minimum filler density is at the first surface. In one embodiment, the composite article is a non-laminated article defining first and second regions wherein the first region encompasses the first surface. The first region has a filler-to-matrix ratio that varies along the transverse dimension, the filler-to-matrix ratio being at a minimum at the first surface. The first region can include one or more additives. A method for forming a composite article includes injecting first and second compositions into a die head at different points so as to produce a partially mixed composition that is discharged from the die head. The second composition contains less filler material than the first composition.
