Patent number: 8318895Abstract: A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.Type: GrantFiled: August 2, 2012Date of Patent: November 27, 2012Assignee: Evonik Stockhausen, LLCInventors: Gonglu Tian, Scott J.

Patent number: 7652190Abstract: An integrated wound dressing system and method including a bandage and a self-contained receptacle that stores treatment material for the care and treatment of wounds. The treatment material is easily accessible and can be removed from the receptacle through an exit. The treatment material can then be used to control bleeding and/or clean the wound before dressing. The bandage may include a layer of plastic that acts as an occlusion barrier to reduce heat loss and maintain moisture levels at the wound site. The occlusion barrier also acts to prevent the passage of air into or out of the wound site. The bandage also includes fasteners that act to prevent unintentional unraveling and to secure the bandage during final packaging. These fasteners help facilitate the wrapping of amputations, stumps, and extremities. The integrated wound dressing system provides an all-in-one system for treating and dressing wounds and reduces the time required to do so.Type: GrantFiled: April 18, 2007Date of Patent: January 26, 2010Assignee: Tactical Medical Solution, Inc.Inventor: Ross A.
