Fluid phase analyzer Patent
Mixed liquid and vapor phase analyzer design with thermocouples for relative heat transfer measuremen
Flow control valve
A flow control valve for high temperature fluids is disclosed. The valve is characterized by an all-metal flow control unit including a tubular conduit, terminating in a valve seat, a throttling cone having an internal, truncated conical surface coaxially related to the valve seat and supported for axial motion relative to the seat, and an axially reciprocable, flow-control plug supported in coaxial relation with the cone. The plug is provided with a truncated conical surface configured to be mated with the surface of the throttling cone for regulating a flow of fluid established through the unit and a curved shut-off surface

Lithium corrosion of niobium zirconium alloys and yttrium oxides at high flow velocitie
Liquid metal magnetohydrodynamics (LMMHD) technology transfer feasibility study. Volume 1: Summary
The potential application of liquid metal magnetohydrodynamics (LMMHD) to central station utility power generation through the period to 1990 is examined. Included are: (1) a description of LMMHD and a review of its development status, (2) LMMHD preliminary design for application to central station utility power generation, (3) evaluation of LMMHD in comparison with conventional and other advanced power generation systems and (4) a technology development plan. One of the major conclusions found is that the most economic and technically feasible application of LMMHD is a topping cycle to a steam plant, taking advantage of high temperatures available but not usable by the steam cycle

Shutoff and throttling valve
Leaktight shutoff, precise flow control, and very low pressure drop are incorporated in all-metal valve designed for operation under extreme temperatures. Valve constructed with refractory metal is intended for control of high-temperature liquid cesium, but has applications related to control of high- and low-temperature liquids and gases
Multicultural Counseling Issues: Practicing Outside Boundaries of Competence
This article examines issues of practicing outside boundaries of competency with regards to multicultural counseling. Using current research from the fields of counseling and psychology, the significance to the field of counseling, attributes of a multicultural counselor, and training necessary for competent multicultural counseling are addressed. Briefly outlined are the three dimensions of counseling competencies needed to be a culturally skilled counselor as well as consideration of the problems in the field of counselor education. This article concludes with a summary of researchers’ suggestions on how to ensure counseling students acquire the appropriate training in developing multicultural competencies to practice ethically
