Patents held by Helen G. Tucker
Number   Title/Abstract
US3952577   Apparatus for measuring the flow rate and/or viscous characteristics of fluids Helen G. Tucker, John W. Tanney, William F. Hayes. An apparatus for measuring the flow rate and/or viscous characteristics of a fluid comprising a casing having a fluid passage, a fluid inlet cavity and a fluid outlet cavity, fluid pressure detecting means preferably at spaced positions along the passage, and fluid pressure indicating means for indicating the or each characteristic to be measured....  
US4003405   Apparatus for regulating the flow rate of a fluid William F. Hayes, John W. Tanney, Helen G. Tucker An apparatus for regulating the flow rate of a fluid, comprising a casing having an annular or cone-shaped fluid passage, for radial flow (inwardly or outwardly) between an inlet and outlet which are spaced radially and form unobstructed flow paths....
