A fire alarm system which makes fire determination based on a novel idea which considers various changes of the physical phenomena in the surroundings caused in relation with the occurrence of a fire in terms of changes of vectors. These changes in the physical phenomena are detected by the detecting section in the form of analog data and processed by a data sampling section as sampled data and st...

A method of forming a hydrophlic coating on a substrate comprised of applying a hydrophilic copolymer capable of chemically reacting with a coupling agent which will promote adhesion to the substrate. A polyisocyanate coupling agent is applied to the surface from a solvent solution followed by applying the hydrophilic copolymer from solvent solution. In certain instances, the copolymer and isocyan...

A latex of crosslinked silicone is prepared by emulsifying a vinyl endblocked polydiorganosiloxane and an organosilicon compound having silicon-bonded hydrogen atoms with water and surfactant, adding a platinum catalyst and then heating the emulsion to form the latex. Colloidal silica can be added to the latex to provide a product which is tougher. The water in the latex can be evaporated to provi...

There are disclosed thermosetting resoles containing chemically bonded boron, tungsten and/or zirconium atoms. These modified phenolics are prepared by reacting a resol with zirconyl acetate, boric acid, or a tungsten carbonyl/pyrrolidine reaction product. The metal containing resoles of this invention are useful, for example, as reimpregnation resins for carbon/carbon composites.
