InactiveUS20110228529A1Effective coolingIncrease airflowMechanical apparatusPoint-like light sourceSolid-stateAir current
A lighting fixture utilizing LED light sources for illumination of commercial, outdoor and other large area applications incorporates efficient heat dissipation and improved convective air flow. An integrated heat transfer assembly is disclosed that is configured to enhance heat dissipation by providing an efficient thermal conductive pathway for radiation of heat to an external environment. The lighting fixture body is configured with a lens body and heat sink having a chimney tube with internally facing finned heat sink arrangement for providing enhanced convective air flow through the light fixture body. When the heat sink transfers heat from the LED light sources during operation so as to create heated air surrounding the heat sink, ambient air is drawn through the chimney and the heated air is exhausted through air gaps so as to create a conductive air current with the environment. The heat sink fins are configured to enhance the natural air draw through the chimney by tapering the surface areas of the fins.

The basic structure of a PTV (programmed temperature vaporizer) injector has been considerably modified so that is can be used for the direct coupling of liquid chromatography in normal phase or reverse phase, and gas chromatography and also for the introduction of high volumes in gas chromatography. The glass tube of the injector is filled with an adsorbent. By means of a system of valves and tubes or capillary tubes, the previously selected fraction of liquid chromatography is transferred to the injector, said fraction coming in through the same extremity for introducing the gas chromatography column. The eluent is entrained by a gas stream through the adsorbent, wherein are retained the solutes, and the solvent is removed through a tube or capillary tube introduced in the injector through the opposite extremity. Thereafter, the solutes are desorbed thermally passing to the chromatography column.

The present invention provides an apparatus 1 for the treatment of air comprising a low power corona discharge ozone generator 5,6 inside a chamber 9 having an inlet 2 and an outlet 7, and at least one air flow impeller 3 for inducing a flow of air through the chamber 9. The ozone generator 5,6 is formed and arranged for generating a restricted concentration of ozone, within an inactivating zone 10 contained within the chamber 9, through which the air flow is passed. The restricted concentration is sufficient to inactivate airborne pollutant material entrained in the air flow, yet decays sufficiently outside the inactivating zone so that the concentration of ozone in the cleaned air expelled from the apparatus 1 is at a physiologically acceptable level without the use of an ozone decomposition catalyzer.
