    Abstract: A device for the automatic addition of a corrosion inhibitor to a cooling system, such as in an automobile engine, utilizing osmotic pressure. The device includes a container for a concentrated corrosion inhibitor solution with a semi-permeable osmotic membrane in contact with and separating the inhibitor solution from the coolant in the overflow reservoir. With properly inhibited coolant, the osmotic pressures balance, but if the level of inhibitor in the coolant drops, water passes through the membrane to force inhibitor solution through an overflow tube or opening to mix with the coolant and raise the inhibitor level therein to a predetermined value.

    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)
