Electrolytic dispensing device
First Claim
1. An electrolytic dispensing device, comprising:
- a housing having a displaceable member therein dividing the interior of the housing into a first contractible chamber for receiving a liquid to be dispensed, and a second contractible chamber for receiving a gas to control the rate of dispensing of the liquid from said first chamber;
and an electrolytic cell adapted to contain an electrolyte, said cell including a pair of electrodes connectible to a source of electrical current for generating a gas and for feeding the gas to the second chamber in accordance with the electrical current conducted through the electrolyte via the electrodes;
characterized in that said electrolytic cell includes a partition of an ion-permeable, but gas-impermeable, material separating said two electrodes and effective to permit gas generated at one of said electrodes to be fed to said second chamber, and to block from said second chamber gas generated at said other electrode.

Abstract
An electrolytic dispensing device includes a first contractible chamber for receiving a liquid to be dispensed, and a second contractible chamber for receiving a gas to control the rate of dispensing of the liquid from the first chamber. An electrolytic cell generates a gas which is fed to the second chamber to dispense liquid from the first chamber in accordance with the electrical current conducted through the electrolytic cell. The electrolytic cell includes a partition of an ion-permeable, but gas-impermeable, material separating its two electrodes. The partition is effective to permit gas generated at one electrode to be fed to the second chamber, and to block from the second chamber gas generated at the other electrode, and thereby to prevent the formation of a hazardous mixture of gases.
