摘要:
The present invention discloses a flame retardant formulation comprising tetrabromobisphenol A bis(2,3-dibromo-propyl ether) (FR-720) particles in a liquid carrier, wherein the particle size of at least 50% of said particles (d50) is smaller than about 50 microns. Furthermore, the present invention discloses a flammable textile fabric, coated by a flame retardant film comprising FR-720 particles which are substantially homogeneously dispersed in or on the flammable textile fabric, and further of a process of preparing these flame retardant formulations and of a process of applying these formulations onto a flammable textile fabric.

Materials for, and methods of protecting yarns, fibers, fabrics and finished textiles from the deleterious effects of ultraviolet radiation. The materials include at least one physical UVR attenuator, having an average particle size below 1000 nanometers, and at least one flexible, film-forming polymeric binder for bonding the material to a fabric surface, wherein the physical UVR attenuator is dispersed within said binder to form an aqueous dispersion. Also disclosed are materials including both physical and chemical UVR attenuators, in which a synergistic protection effect is achieved.

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.
摘要:
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.

The present invention discloses novel halogenated flame retardant formulations that effectively flame retard textiles at low binder and/or the flame retardant synergist contents, novel modes of application thereof on textiles, and flame-retarded textile fibers and fabrics which are treated by these formulations.
摘要:
A dyeing apparatus and method for continuous dyeing of a fabric article with dye, the apparatus including: (a) a dyeing vessel for containing a high-density liquid; (b) a heating mechanism, thermally associated with the dyeing vessel, for heating a dye fixation zone within the vessel to a temperature above 70° C.; (c) a continuous transport mechanism for continuously transporting the fabric article, through a dye impregnation chamber, and through the dye fixation zone of the dyeing vessel, and (d) a dye-dispensing mechanism for delivering a dye liquor within the dye impregnation chamber, so as to impregnate with the dye, the fabric article passing through the chamber, and wherein the dyeing vessel is dimensioned and configured such that a height of the high-density liquid delivers a hydrostatic pressure of at least 0.1 bar gauge to the dye fixation zone, so as to effect fixation of the dye in the fabric article.

摘要:
In an airfield with a short bi-directional runway and a long bi-directional runway intersecting with each other perpendicularly a system for storing and launching a plurality of airplanes includes a plurality of platforms, a plurality of rectangular cages and a frame. Onto each platform one airplane may be placed. Each cage has an opening into which one platform and one airplane are inserted through the opening. The frame has a plurality of slots and is disposed in ground beneath the airfield. One rectangular cage may be inserted into one of the slots. An elevator is disposed adjacent to the frame and has a bottom platform and an opening which may be aligned with the opening of one of the slots.
摘要:
Flame retardant aqueous dispersions or suspensions comprising tris(tribromophenoxy)-s-triazine (TTBT) or tetrabromobisphenol A bis(2,3-dibromopropyl ether) (TBBPE) or a mixture thereof and one or more nonionic or anionic surface active agent(s) and/or wetting agent(s) used in textile are described. The flame retardants exhibit high compatibility with textile materials and are stable in aqueous solutions.
摘要:
Novel smoldering suppressing compositions containing a metal complex of ammonium superphosphoric acid and having a high phosphate content, and processes for their preparation, are disclosed. Further disclosed are formulations containing these compositions and articles-of-manufacture having these formulations applied thereon. These novel formulations are particularly effective as smoldering suppressants for textiles, and are characterized by a high washing fastness.
