Abstract: Methods for authenticating an article with a cyanoacrylate solution comprising a water soluble security marker compound are described. The methods for producing a nucleophilic security marker/cyanoacrylate solution as well as methods for labeling an item and detecting the nucleophilic security marker/cyanoacrylate from an item being authenticated are also described. A method for using a nucleophilic cyanoacrylate security marker for antitheft purposes is also described.

Abstract: A fuel atomizing unit interposable in a conduit feeding a relatively cold mixture of fuel droplets dispersedd in air to a combustion chamber. The unit includes a permeable assembly constituted by an electrical heating element disposed between a pair of spaced mesh screens to define an atomization zone. The assembly is seated in a cavity formed in a metal plate having a flow passage which registers with the flow conduit, the plate acting as a heat sink and being sandwiched between thermal insulation gaskets to render the plate effective as an oven chamber to maintain the atomization zone at an elevated temperature despite the varying cooling effect of the incoming mixture. The zone restricts the flow of the mixture, the screen intercepting the droplets therein to create a suspension of minute fuel particles to produce a downstream mist.

Abstract: A fuel atomizing unit interposable in a conduit feeding to a combustion chamber a relatively cold mixture of fuel droplets dispersed in air. The unit is constituted by an electrical heating element placed between a pair of spaced mesh screens to define a permeable assembly having a pocket therein. The assembly functions as a restriction in the conduit whose impedance to flow is in the order of about 15 to 20%, whereby the screen intercepts the droplets to create a suspension in air of minute fuel particles to produce a downstream mist which is forced by the restriction to assume a vortex-like flow pattern. The heat supplied to the pocket by the heater is sufficient to raise the temperature of the mist to a level conducive to complete combustion in the chamber, whereby no fuel is wasted and the exhaust of the chamber is substantially free of pollutants.
