  • Publication number: 20180258287
    Abstract: The present invention is directed to a biocompatible and biodegradable natural disperse dye for dyeing polyester fabrics which is dispersed in water and derived from green plants. The disperse dye contains as the active dye compound an acid bewchlorophyllin derivative such as acid form Mg-chlorophyllin or acid form Cu-chlorophyllin. The disperse dye of the present invention can be used for the dyeing of polyester fabrics by traditional methods in concentrations ranging from 0.01% to 20% on weight of fibers (OWF), thus providing a dyed fabric with good color strength and good fastness to light, washing and rubbing, under conditions of dye exhaustion of greater than 90%.

  • Publication number: 20170015439
    Abstract: A portable runway includes a sheet of thermoplastic composite materials that is rolled out to form the runway track and then heat cured in place to form a rigid. Suitable composite materials are glass, carbon or aramid fibers are co-mingled with thermoplastic fibers such as polyamides, polyolefins, polyesters, polyacrylates and polyimides so that the pliable co-mingled materials is in either fiber bundle (“tow”), yarn, braid, fabric or non-woven forms are layed down on the pregraded earth by unrolling, unstacking, unfolding, dispesing or spraying. Once in place the composite materials are consolidated and hardened by application of heat. The width of the surface of said portable runway may range from 1 meter to 25 meters. Anchoring pegs may be inserted along the edges of said portable runway prior to curing with the thickness of the surface ranging from 1 cm to 50 cm and the areal weight of the surface ranging from 50 grams per square meter (GSM) to 2,000 GSM.

  • Publication number: 20170007865
    Abstract: An intelligent method of fighting a forest or brush fire in a remote area including the steps of targeting the remote area by means of an aerial surveillance device and generating a map of the forest or brush fire. The method also includes the step of delivering a plurality of containers to the remote area. Each container contains a fire retardant material and an explosive device. Each of container has a GPS locating device. a position transmitting device and a remote detonating device electronically coupled to the explosive device. The method further includes the steps of locating the position of each container, selecting according to a plan which of the containers are to be selected to be detonated and remotely detonating the selected containers. The forest or brush fire can be either extinguished or contained in an intelligent manner. An individual generates the plan according to which of said containers are to be selected to be detonated in order to maximize effectiveness of said intelligent method.
