A burner comprises a central passageway and outlets for fuel and for stabilizing oxidant arranged peripherally around the central passageway, and comprises outlets within the burner through which biasing gas, such as gas comprising oxygen, can be injected to enable control of the direction of the flame that is generated by combustion of the fuel and the oxidant at the face of the burner.

Fluidic burner with heat stability

A burner that is useful for providing a melting flame whose axis can be altered during operation, and for providing a supersonic jet of oxidant that can penetrate through the surface of the molten material, has a unique combination of features including a specially contoured flame collar at its open discharge end.

Multifunctional fluidic burner

The present invention relates to formation of a controllable, high velocity, pneumatic stream of particulate solids which can be injected into a furnace containing, for instance, a liquid such as a bath of molten metal.

Controllable solids injection

A valve useful in distributing gas received in one inlet to several outlets in a sequence, and burner apparatus including this valve for feeding material in sequence to outlets of a burner thereby forming a non-stationary flame at the burner.

Multi-output valve and burner useful to promote non-stationary flame

A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.

An inhaler comprising a compressed gas, such as Heliox gas is provided. The disclosed inhaler includes a first chamber containing a compressed gas which is in communication with an equalization chamber having pressure lower than the pressure of the gas in the first chamber. The inhaler also includes a drug storage chamber which is detachably coupled to the equalization chamber and operable such that a portion of the compressed gas from the equalization chamber fluidizes and aerosolizes the drug to produce a drug cloud. The drug cloud is directed into a spacer where it can be inhaled by a user.
