Abstract: An improved cellulose acetate implant is able to more cost effectively provide ovulation of female fish. The time required for a production run of implants in CA is about 2-3 hours rather than days of the previous procedure. The method of generating the improved implant includes dissolving a hormone in water, adding acetone to the solution, adding cellulose acetate to the solution, mixing the solution, generating the CA/LHRH from the solution such as by extrusion and processing the CA/LHRH such as drying and cutting the CA/LHRH into strips of improved implants. Other polymers, substances and additives are also able to be used. The improved implants are then able to be inserted into fish at the proper time to increase ovulation which ultimately results in an increased number of fish.

Abstract: N-halaminehydantoinyl epoxide compounds which can be used for the construction of coatings and materials which can be rendered biocidal by exposure to halogen solutions either before or after curing the coating or material are disclosed. The biocidal coatings and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew. The coatings are compatible with a variety of substrates including, but not limited to, cellulose, chitin, chitosan, synthetic fibers, cement grout, latex caulk, acrylic films, polyurethanes, plastics and paints.

Abstract: N-halamine compounds which contain hindered amine and amide functional groups. Compounds include wherein X, X?, and X? independently are H, Cl, or Br, wherein no more than two of X, X?, and X? are H and wherein R, R?, and R? are independently alkyl groups containing 1 to 4 carbon atoms or hydrogen, and X and X? are independently H, Cl, or Br. Compositions comprising the compounds are also described. The compounds and/or compositions can be used, for example, for the purpose of constructing biocidal coatings and materials. The biocidal activity can inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as, virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring, such as mildew.

Abstract: A fabric forming device including a stationary yarn supply and a rotating yarn supply, each delivering yarn to a common point along a vertical axis where they are interlaced. The stationary yarn supply includes a plurality of yarn carrying cones which are arranged along a common horizontal plane about the vertical axis. The rotating yarn supply includes a plurality of yarn spools mounted with a rotating plate about the vertical axis. A plurality of vertically moveable guide members which are adapted to engage with the yarns of the rotating yarn supply act to selectively alter the horizontal path along which the yarns travel. The guide members act to control the yarns of the rotating yarn supply to be selectively positioned to pass above or below the cones carrying the stationary yarns so that the yarns interlace in a desired manner.
