  • Patent number: 4432470
    Abstract: A portable apparatus for mixing and dispensing interactive liquid components (such as epoxy resins and catalysts) which utilizes reciprocable positive displacement pumps which are mechanically connected for simultaneous pumping and filling movement, there being a common single acting selectively adjustable drive for effecting only output pumping movement at preselected output pressure, and the pressure exerted by the liquid components themselves are required to hydraulically effect the filling movement, with the amount of hydraulic filling pressure which can be exerted by one of the component liquids being specifically regulated to be less than that required to effect filling movement. This insures maintenance of precise ratio mixing since the filling movement requires exertion of hydraulic filling pressure by both of the component liquids thus assuring precision ratio pump filling at all parts of the filling cycle independent of varying temperature dependent viscosity of the liquids.

  • Patent number: 4403764
    Abstract: An improved method for precision control of a wide variety of work material liquids and an improved pinch valve incorporating that method is disclosed. The method involves constricting a discrete site on a resilient tube having liquids flowing therethrough to pinch off flow, then moving the constriction upstream to maintain flow stoppage and create a partial vacuum to cause positive suck back, the distance the constriction is moved being selectively determinable to selectively adjust suck back. An apparatus for practicing the method comprises an external roller shutoff member which is movable in a direction to intersect with and then move counter to work material flow within a resilient tube to compress the tube against a ramp and gives positive repeatable shutoff of the flow.
