First Claim
1. A device for actively releasing material(s) comprising or includinga housing having a plurality of reservoirs each having an outlet from said housing, material(s) to be released in each of said reservoirs, closure means for at least some of said outlets to protect the material(s) from passive release, an electrolytic cell for each of said reservoirs having closure means, each electrolytic cell being capable when activated of generating a gas which will cause by displacement of the material(s) of its respective reservoir sufficient displacement of or change to the closure means of that reservoir thereby to allow release of the material(s), and means to activate selectively each electrolytic cell.

Abstract
A device for actively releasing material(s) (e.g. intra ruminally) having a plurality of dispensing reservoirs. Each electrolytic cell is capable upon energization under the control of a microprocessor after initiation of generating a gas which will cause (e.g. through action on a piston) by displacement of the material(s) of its respective reservoir sufficient displacement of or change to closure means of that reservoir thereby to allow release of the material(s).

18. An intra ruminal device comprising or including
means defining multiple reservoirs each having an outlet, each said reservoir being of a kind which will allow the movement of plungers or pistons towards the outlet of said reservoir, a plunger or piston positioned in each said reservoir, material(s) to be released interposed between each of said plungers or pistons and the outlet of its reservoir, an electrolytic cell for each reservoir, each cell being capable of generating a gas when activated to cause by action on its plunger or piston movement of the assemblage of material(s) out of said outlet, and means to selectively activate each said electrolytic cell, the construction and arrangement being such that after intra ruminal insertion of the device, the means to selectively activate each said electrolytic cell can present serially the different masses of the material(s) within the reservoirs to or into the rumen.
