A flash curing system for solid freeform fabrication which generates a plurality of radiation emitting pulses that forms a planar flash. The planar flash initiates curing of a curable material dispensed by a solid freeform fabrication apparatus. The radiation emitting pulses have a high peak power value that releases a sufficient quantity of free radicals from the photoinitiator to initiate curing and overcome the problem of oxygen inhibition. Substantially less power is consumed and less heat generated by the flash curing system compared to conventional continuous emission curing systems.

The present invention is related to methods and apparatus for improving distributions of both spent catalyst and transport gas into a regenerator of a fluid catalytic cracking unit. Spent catalyst and transport gases move upwardly through a spent catalyst riser and are diverted in a radially outward direction by a deflector cone. The catalyst and transport gas are re-mixed as they move radially outward between two disks before discharging from the outer edges (perimeter) of the distributor into the regenerator in a substantially uniform radial direction. The distributor is adapted to provide continuous discharge from its perimeter so as to cover the entire cross-section of the regenerator.

The invention provides an emitter and an emission device. When a driving seat moves, a plurality of movable blocks are converted into an unlocking state from a locking state, and are dispersed around to form a dispersed and emitting effect, so that targets in a plurality of directions can be attacked and the attacking precision is improved; after the movable blocks are unlocked, the driving seat and a driving rod are unlocked; even if a bullet is blocked by an obstacle and stops running, the driving seat and the driving rod still move frontwards along a channel under the action of inertia, so that the front end of the driving rod stimulates a power medium and a cap head is emitted, and furthermore, continuous emission is carried out; a target range and precision of attacking are further improved.

A lighting apparatus for controlling a plant disease is provided to reliably inhibit a spore formation and a hyphal growth of a filamentous fungi, reliably induce a disease resistance, prevent a leaf scorch, and promote a growth of a plant. A UV light source repeats a light irradiation which has an irradiation pattern of combining a light irradiation, in which UV-C and UV-B and a visible light are superimposed, with a visible light irradiation alone at least twice a day.

The disclosed invention relates to a calibration method, system and apparatus for a multimetals continuous emissions monitor system (hereinafter "multimetals CEMS"). More specifically, this invention relates to a calibration scheme for continuous monitoring of mercury emissions from stationary sources by plasma emission spectrometry. A source of mercury vapor, preferably a mercury permeation tube, entrains mercury vapor into a constant flow of carrier air. The carrier air mixes with a constant flow of diluent air in an aerosol mixer. The mixer is operably coupled to the analyzer. A gaseous mixture having a calibration mercury concentration flows from the mixer into the analyzer at a constant rate. A graph having coordinates of analyzer signal intensity and mercury concentration is used to plot the calibration scheme. A first signal intensity generated by the analyzer in response to the calibration mercury concentration is used for the first plot on the graph. A second signal intensity generated by the analyzer in response to a blank having zero mercury concentration is used as the second plot on the graph. A linear relationship between the analyzer signal intensity and the mercury concentration on the graph is established from the first plot and the second plot. The slope intercept and slope are used to create a mathematical relationship between the analyzer signal intensity and the mercury concentration. This enables the analyzer to be calibrated by inserting a known mercury concentration into the analyzer and adjusting the signal intensity to conform to the signal intensity calculated from the graph or mathematical relationship.
