Abstract:
An element for use in an electrochemical cell has a first zone for introducing an oxygen-containing gas and a second zone separated from first zone by the element, which has a membrane with first and second surfaces, conducts oxygen ions therebetween, and has a catalyst exposed to at least the first zone. The element may be used to separate oxygen.
Abstract:
PURPOSE:To form easily a flow with a uniform distribution of velocity, by installing a distribution plate which causes a large pressure loss in a fluid passage to eliminate the presence of dead zone when fluids are diffused from a fluid inlet into a passage having a larger sectional area. CONSTITUTION:A distribution plate 2 is disposed in a fluid passage in a diffuser 1 so that the pressure drop caused by the fluid when it passes through the distribution plate 2 is much larger than that caused by the fluid when it flows radially outwardly through the space 3 between the plate 2 and a fluid inlet 5. The distribution plate 2 is made of porous plate of sintered metal etc., having pores with a diameter of 3-7mum, while the depth of the space 3 is made 5mum-1cm to make the pressure loss within the space 3 sufficiently small. As a result, on both sides of the distribution plate 2, no change in concentration of the fluid occurs and the fluid does not separate from said plate, causing a good piston flow of the fluid thereafter.
Abstract:
An osmotically driven distributor for use in a liquid medium comprising: a substantially rigid case, a moving diaphragm within the case dividing the inside thereof in a first compartment and a second compartment, arranging the portion of the case defining the first compartment of an outlet duct and the portion of the box defining the second compartment being semipermeable; an active agent composition contained within the first compartment and filling the latter; and an osmotically effective composition in the second compartment that imbibes liquid from the medium through the box to the second compartment causing a pressure to be exerted on the mobile diaphragm and the active agent composition to be displaced from the first compartment in response to that. Pressure through the outlet to the middle. (Machine-translation by Google Translate, not legally binding)
