Abstract: Mixing means, for producing a flow mixture of oil and steam, is combined with an atomizing nozzle to provide a nozzle assembly which produces a jet of very fine oil droplets. The nozzle assembly is used in conjunction with a reactor, such as a fluidized bed coker. The mixing means comprises a pipe, external of the reactor, having separate, spaced apart inlets for oil and steam. The steam inlet is upstream of the oil inlet. A reducing diameter nozzle is positioned in the pipe bore between the inlets, for accelerating the steam. The steam contacts the oil and turbulently moves down the pipe bore to produce what is known as a "bubbly flow" mixture. The mixture is fed to the nozzle, which is internal of the reactor.

Abstract: An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent portions on opposed surfaces thereof. The fluorescent portions of said arms comprising spaced walls and each wall has at least one opening therethrough. The opening in one wall is staggered with respect to the opening in the other wall such that portions of one wall overlie the opening in the other wall and such that air striking the device flows in a sinuous path through the device reducing the drag on the device.

Abstract: An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent means on opposed surfaces thereof. Vane devices are constructed and arranged, shaped and positioned on the equilateral triangle and such that air flow against a face of the triangle produces a downward force tending to prevent movement of the device relative to a road surface.
