ABSTRACT:
A tension-actuated submerged dispenser for discharging a liquid of one composition into liquid surroundings constituted by a liquid of a different constitution is useful for unattended employment to maintain a certain quality of composition in the surroundings. On the other hand, the quality of composition of liquid in the dispenser can be jeopardized if liquid from outside the container is allowed in, as has been the case with some earlier known submerged dispensers which employed a displacement liquid. In order to develop the necessary pressure to express a liquid through an orifice in a submerged container into which no such displacement liquid is allowed entry, a system of actuating a reduction of enclosed volume by means of tensing a container between opposed end-effectors has been developed. The source of pulling force can be either an externally attached weight or float, or a dispensed liquid which is differentiated as to specific gravity from that of the liquid surroundings.
