    摘要: The invention relates to reservoirs with a delivery surface for the controlled delivery of active substances decreasing over the time of use to solid, liquid or gaseous acceptors and whereby at least at one point of the reservoir a cross-sectional surface of the reservoir is parallel to the delivery surface and smaller in area than the delivery surface. The invention also relates to an apparatus for the controlled delivery of active substances decreasing over the time of use, which has at least one reservoir. At least one active substance to be delivered is active in the technical, human and veterinary medical, cosmetic and pest control sectors.

    摘要: In apparatus for separating ions in a solution by countercurrent electrolysis, a generally cylindrical column is constituted by axially juxtaposed annular segments which define respective chambers separated by liquid-permeable partitions. The two axially terminal chambers contain electrodes. Radial bores in the segments permit introduction and discharge of the solution to be tested, of an electrolyte flowing countercurrent to the solution, and of a cooling liquid passing through a cooling coil in each chamber. A shaft axially extending through the column carries agitating blades in each chamber and is magnetically rotated.
