    • A deaerator includes a stationary separation chamber with first and second opposite walls or ends and a peripheral wall in between. Rotating vanes are mounted on a shaft. A large inlet leads to the stationary chamber at the first end and is arranged along a center axis of the chamber. An air reject port lies inside the inlet and is arranged along a center axis of the chamber. The vanes are spaced from the peripheral wall to define a gap. An exit chamber is included at the second end between the vanes and second wall. A vacuum is connected through the air reject port. A variable orifice valve is located at the inlet and outlet. Pressure sensors are also provided at the inlet and outlet. The valves are controlled to regulate the fluid flow, internal level, and pressure in the chamber.

    • A method and apparatus for accurately determining the rheology of a coating fluid and using this information to design application equipment and formulations, particularly for non-Newtonian fluids, including measuring the entrance transition effects for the fluid at process shear rates and time frames, and detecting to presence of dilatant flow. A device for measuring these transition effects has a pressure source for the fluid and connector for a selected capillary tube. The fluid is introduced to the capillary and a pre-determined shear rate and flow rate are achieved. The resulting back pressure in the container is measured. The test parameters are changed to obtain the separate transition effect measurements to correspond to process conditions.

    • A test apparatus and method for predicting the minimum runnable flow of a curtain coating fluid by forcing the coating fluid out of a small round tube opening with less flow rate than is required for momentum to exceed the contracting forces of surface tension. The minimum flow rate is a measure of the combined effects of the surface tension, viscosity, elasticity, and dilitant behavior of the coating fluid which influence the stretch and acceleration of the fluid, that in turn, characterize the runnability of the fluid for a full scale curtain coating process. The velocity of the coating as it lands can also be determined from the flow rate and acceleration to predict whether the coating fluid will run or not before it is applied to a web or substrate.

    • A system for applying a suspension of uncooked starch particles in water to a web on a forming wire includes a source of such suspension and a source of dilution water, an application die positioned transversely of the web with an internal manifold opening into a downwardly opening die slot through which material flows from the manifold as a falling curtain onto the web. The die has a plurality of transversely spaced inlets leading into the manifold to define transversely spaced application zones across the web. The suspended starch and water are applied from the manifolds through control valves into the inlets by means of which the consistency or concentration of the starch may be varied at positions representing the application zones across the web to provide a desired strength profile to the dried web. The method includes the steps of controlling the ratio of starch and water by proportional valve means in accordance with a desired strength characteristic of the web as measured at the dry end of a paper machine and while maintaining a flow from the die at a relatively constant rate of flow into the fallen curtain of material.
