Abstract: An apparatus for measuring fluid flow has a measuring device operating in accordance with the Coriolis principle. The measuring device has an oscillating conduit wherein the fluid to be measured flows through the conduit, and a sensor for sensing the movement of the conduit and generating output signals indicative of the movement. The measuring device generates a measurement signal based on the sensor signal indicative of the flow rate of fluid through the conduit. A counting device is coupled to the measuring device for receiving the measurement signal and calculating the flow rate of fluid through the conduit based on the measurement signal.

Abstract: A nozzle is provided for use in discharging a controlled stream of fluid into a reactor tube of a catalyst unloading apparatus for removing non-packed, non-bridging, and packed bridging flowable catalyst and bead material from within the reactor tube. The nozzle has a main channel running medially along its length for entry and exit of the controlled fluid, and a plurality of unevenly spaced smaller fluid discharge openings positioned around the circumference of the nozzle at such an angle to the central axis of the nozzle so as to discharge some of the controlled fluid in an upward and sideward thrusting manner, such that a sideward and downward thrust is exerted against the nozzle, thereby forcing the nozzle to position itself in a downward manner against the side of the reactor tube. This action allows both the catalyst and the bead material to be removed in one continuous operation.

Abstract: A method for preparing graft polymer dispersions having broad particle size distribution without wildly fluctuating viscosities is disclosed. The method comprises:(a) preparing intermediate graft polyol dispersions containing 30 percent by weight or less solids to achieve a broad distribution of partial sizes in a continuous process and(b) charging the intermediate graft polymer dispersion of (a) to a semi-batch reactor as seeds for further grafting to increase the solids content of the dispersion to above 30 percent by weight. The graft polymer so formed is useful in the production of polyurethanes.
