Heating units, drug supply units and drug delivery articles capable of rapid heating are disclosed. Heating units comprising a substrate and a solid fuel capable of undergoing an exothermic metal oxidation reaction disposed within the substrate are disclosed. These heating units can be actuated by electrical resistance, by optical ignition or by percussion. Drug supply units and drug delivery articles wherein a solid fuel is configured to heat a substrate to a temperature sufficient to rapidly thermally vaporize a drug disposed thereon are also disclosed.

The present invention concerns a burner assembly that includes a burner body having a combustible gas chamber from which a combustible gas is distributed to a plurality of burner ports at which the combustible gas can be combusted and a stability chamber in gas-flow communication with the combustible gas chamber for maintaining the combustion of the combustible gas in the stability chamber whenever the combustion of the combustible gas at the plurality of burner ports is disturbed, whereby the combustion of the combustible gas at the plurality of the burner ports may be resumed upon the cessation of the disturbance. The burner assembly can also include a burner cap for closing off the top of the burner body so as to substantially preclude the escape of the combustible gas from the combustible gas chamber, the stability gas chamber and the burner ports at the top of the burner body.

A melting plate candle assembly includes a wick holder that retains a wick spaced above a melting plate and a base portion having one or more capillary paths disposed therein that are adapted to draw liquid, such as melted candle wax, from a pool retained on the melting plate to the wick by capillary action therein.

Compositions are provided which, when burned, produce significant levels of infrared radiation, but only limited levels of visible radiation. The basic components of the compositions include a binder, an oxidizer, and a fuel, where the binder also acts the fuel. Preferred oxidizers include those compounds which produce large quantities of infrared radiation when the flare composition is burned. Such oxidizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these compounds. Selection of the binder is important in order to provide the composition with the desirable characteristics identified above. The binder of the present invention does not produce significant soot. At the same time, the binder serves to form a composition which is processible, avoids chunking, and is compatible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continuous carbon atoms) are preferred. Examples of such polymers include polyesters, polyethers, polyamides, and polyamines.
