  • Publication number: 20030104341
    Abstract: A teeth whitening system including a thermally conductive mouthpiece that carries a teeth whitening agent and that is connected to a thermally-chargeable heat sink. The system controls the flow of thermal energy from the heat sink in order to provide thermal activation of whitening agent. The system may include a catalytically-enhanced teeth whitening device for receiving the whitening agent and promoting enhanced teeth whitening by the whitening agent. The teeth whitening device may be used with or without the application of supplemental heat or light for further augmenting whitening reactions of the whitening agent. The teeth whitening device may include a substrate that may be fabricated from a catalytic agent useful for enhancing tooth whitening by the teeth whitening agent. Alternatively, the substrate may be covered, coated, impregnated or otherwise contacted by a catalytic agent in an amount effective to enhance tooth whitening by the teeth whitening agent.

  • Patent number: 4331080
    Abstract: A novel composite explosive comprised of conventional explosive material and a mixture of boron and at least one other metal is disclosed. The other metal must be capable of exothermically reacting with boron to produce intermetallic compound and an energy release of at least about 1.0 kcal/gm. In a preferred embodiment of the composite explosive, pellets of a stoichiometric mixture of boron and titanium are mixed with cyclotetramethylenetetranitramine (HMX). By mixing the boron and at least one other metal which forms an intermetallic compound with boron in an exothermic reaction wherein the heat energy release is at least about 1.0 kcal/gm and adding a conventional explosive material to the mixture, there is an improved method of forming a mass of hot or molten particles in an environment when the conventional explosive is detonated.

  • Patent number: 4152120
    Abstract: Pyritic and organic sulfur is removed from pulverized coal by contacting the coal with an alkali metal or alkaline earth compound and thereafter using low amounts of electromagnetic energy to preferentially heat sulfur rich regions of the coal-alkali compound mixture. The alkali compound reacts with the sulfur within the coal to form water soluble, or separated compounds of sulfur which can easily be removed by washing the treated coal with water and/or to form compounds which do not convert into sulfur oxides during combustion of the coal.
