Abstract
A mechanism to control the size of particles flowing through it, even to the nanometer scale, that contains a beam or plate effectively anchored at the bottom of each of a plurality of adjacent chambers, and, wherein the top of the beam or plate and the bottom of the chambers are polished to a degree finer than the particle size to be excluded, and with the polished surfaces normally brought into intimate contact to close off the chambers; an extension to the beam or plate acting as a force source to the beam or plate, such that when the extension is deflected a known large amount, the resulting deflection in the neighborhood of the anchoring point is very small, enabling the extension to create a transmission effect with the bending of the extension down, making the beam or plate act like a cantilever and opening the system for flushing; while bending the beam up, puts the beam in three point bending, and guides the substances from one chamber to another, with appropriate exit seal.
