Patent number: 5885602Abstract: The invention provides contaminant-reducing agent delivery compositions that are useful for the control of organic or inorganic contaminants in aquatic or terrestrial environments. The compositions comprise one or more superabsorbent solid organic polymers and at least one contaminant-reducing agent. These superabsorbent polymers act as the primary carriers of one or more contaminant-reducing agents effective for the control of organic or inorganic contaminants in aquatic or terrestrial environments. Contaminant-reducing agents include film-forming agents, microbial agents, nutrient agents, and mixtures thereof. The invention also provides a method to entrap and accumulate organic and inorganic contaminants in one or more superabsorbent polymer compositions containing no contaminant-reducing agent. The invention also provides a method to entrap water in superabsorbent polymers to activate natural and applied microbial and nutrient contaminant-reducing agents in terrestrial environments.Type: GrantFiled: May 27, 1997Date of Patent: March 23, 1999Assignee: Lee County Mosquito Control DistrictInventor: Richard Levy

Patent number: 5718954Abstract: Materials containing fine natural organic material particles are disclosed. As the fine particles, superfine silk fibroin particles are produced by a process comprising a first step of comminuting silk fibroin into coarse particles with dry mechanical comminuting means, a second step of comminuting the coarse silk fibroin particles into fine particles with dry mechanical comminuting means, and a third step of comminuting the fine silk fibroin particles into superfine particles with an average particle diameter of 10 .mu.m or below with dry mechanical comminuting means, the silk fibroin particles being beta-treated during or after at least one of the first to third comminuting steps. Specific examples of the material are films, sheets, paints, fiber treating materials, etc.Type: GrantFiled: July 17, 1995Date of Patent: February 17, 1998Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Masahiro Sano, Satoshi Mikami, Nobutaka Sasaki, Nobuo Kusamoto, Fumioki Fukatsu, Atsuhiko Ubara, Takaharu Yasue, Shigeru Ohyama
