Abstract: A flow regulator is provided in a liquid delivery line. The flow regulator includes flow regulation a body having an inflow port through which liquids different from each other in a property such as density, viscosity, etc flow in the body, and an outflow port through which the liquids flow out from the body. A set of rotators, which are rotated within the body in respective directions opposite to each other is provided to move the liquid by given volumes along the internal wall of the body. And a drive unit for driving the set of rotators is also provided. This construction provides an apparatus which can be used for delivering a liquid, which, in delivering liquids different from each other in viscosity, a given volume of the liquid can be accurately delivered to a liquid delivery line in a continuous manner even though the viscosity of the liquids have varied.

Abstract: A water purification apparatus and methods for the purification of water are provided. The invention features an atmospherically-isolated, but ventable, reservoir electrolysis cell with control features for selecting an electrolysis duration depending on temperature, time since last electrolysis, or time since last gas venting. The device and associated method can easily take a wide range of input water qualities into account for the production of an effective amount of sterilizing water.
