Abstract: A theft deterrent dispensing unit particularly for use with cans includes a conveyor section that leads to a dispensing head. A shroud extends over the forward edge of the conveying section. The dispensing head pivots downwardly allowing the leading can to be grasped without interference of the shroud. The rear edge of the dispensing head pivots upwardly, preventing the next adjacent can from moving immediately into the dispensing head until the dispensing head rotates back to a closed position. Likewise, when the dispensing head is rotated to an open position, a barrier is pulled down from the top of the shroud, again preventing an individual from reaching in and grabbing the next adjacent can. A locking mechanism is positioned on the side of the dispensing units to prevent two adjacent dispensing units from being opened at the same time. Finally, the speed at which the dispensing heads move from an open to a closed position is regulated to prevent rapid removal of cans from a single dispensing unit.

Abstract: Method and apparatus for reducing NOx production during air-oxygen-fuel combustion by providing a central core of fuel surrounded by a sheath of oxygen at a combustion end of an air-oxygen-fuel burner. Diametrically opposed air passages are provided on either side of the oxygen sheath to permit entrainment of furnace gases into a flame zone created by primary combustion of fuel and oxygen. Oxygen can be introduced into each air passage to enhance combustion with low NOx emissions.

Abstract: A method and apparatus for blanketing the surface of material, e.g. molten metal contained in an open top vessel, e.g. induction furnace, by establishing a swirling flow of an inert gas having a density greater than air at the top of the vessel. Inert gas exits the swirl flow through an opening in a flow controlling apparatus having an exit opening with a diameter that is smaller than the base diameter of the swirl adjacent the open top vessel.

Abstract: A fire protection material, suitable for use as a coating for structural members, produced by mixing a lightweight refractory aggregate including magnesia with ammonium phosphates in aqueous solution, wherein the composition of the phosphates is at least about 20% by weight polyphosphates, balance orthophosphate, and allowing the mixture to set as a fire protection coating or body having a bulk density of not more than about 50 lb./ft..sup.3.
