Abstract
A deformable polymeric member is drawn or forced through or over a die at an imperceptible rate of travel whereby the visco elastic characteristics of the polymeric member delay and control the displacement for external utility. With appropriate components, force selection determines rate of displacement. Embodiments include long term lubricators and self powered medication infusers.
