28 Sep 2007TL;DR: In this article, an inspection system consisting of a done-shaped diffuser, a camera lens hole, and a plurality of bright-field lights (1250) mounted on the diffuser was presented.
Abstract: An inspection system comprising : a done-shaped dif fuser (1100) def ining a camera lens hole ( 1300) in a top portion of said diffuser (1100), said dif fuser (1100) adapted to receive at least one set of low angle lights (1600 ); and a plurality of bright-f ield lights (1250) mounted on said dif fuser (1100) in proximity to said camera lens hole (1300)

TL;DR: In this article, the treatment of water by a biological technique is described, where the water to be treated circulates in the interior of the reactor, in the space (2) located above the partition (1), it is aerated and agitated by a diffuser (3); it enters the reactor by the opening (4) and leaves by opening (5).
Abstract: The treatment of water by a biological technique. The water to be treated circulates in the interior of the reactor, in the space (2) located above the partition (1). It is aerated and agitated by a diffuser (3); it enters the reactor by the opening (4) and leaves by the opening (5). A volume of confined water, poor in oxygen, occupies at the bottom of the reactor the space (6) located below the partition (1) and has across its thickness a layer supersaturated in oxygen (10) occupied by the microalgae and aerobic microorganisms; a region rich in oxygen (11) occupied by aerobic microorganisms; a region (12) poor in oxygen and occupied by anaerobic microorganisms; and an intermediate region (13) occupied by aerobic and anaerobic microorganisms. The invention is applicable particularly, in its closed circuit configuration, to aquaria and by means of either a closed circuit or an open circuit, to the treatment of water.

TL;DR: In this article, the authors present CFD simulations of different diffuser elements used in valve-less diffuser pumps and nozzle elements in dynamic micropumps and compare the results with measurements and with analytic expressions based on empirical results known from basic fluid mechanics.
Abstract: This paper presents CFD-simulations of different diffuser elements used in valve-less diffuser pumps and nozzle elements used in dynamic micropumps. The results are compared with measurements and with analytic expressions based on empirical results known from basic fluid mechanics. The working principles of the diffuser element in the valve-less diffuser pump and the nozzle-element in the dynamic micropump are investigated.

TL;DR: In this paper, the authors compared the catalytic diffuser and the forced through flow (FVP) concept and discussed their application for hydrogenation processes, like catalytic nitrate/nitrite reduction in water and the dechlorination of chlorinated hydrocarbons.
