A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

The simultaneous measurement of mass flow rate and quality of low-quality steam-water flows is of primary interest in evaluating and monitoring the flow from geothermal resources. The experience acquired at LLL in attempting to perform such measurements with a double flash (meter-valve-meter) arrangement using orifices and venturis is related. The mass flow correlations proposed in the literature are reviewed and a new correlation based on the energy equation is introduced. The data are presented and evaluated in light of these correlations. Directions for future research in this area are suggested.

This material was generated as part of a seismic case review of the NFS Reprocessing Plant. This study is documented in UCRL-52266. The material is divided into two parts: mathematical model information, and ultimate load calculations and comparisons. (DLC)

Present lower limits on the mass of a neutral fermion N coupled with full strength to an electron via the right-handed weak current are set only by the absence of the decay K/sup +/ ..-->.. Ne/sup +/: m(N) approximately greater than 0.5 GeV/c/sup 2/. It is shown that searches for the decays tau ..-->.. ..nu../sub tau/Ne or F ..-->.. Ne, followed by N ..-->.. e..pi.., can raise the lower bound on m(N) to well over 1 GeV/c/sup 2/ if no signal is seen in present or soon-to-be-acquired data. Estimates for the branching ratios for these processes are given. If N couples to e cos phi + ..mu.. sin phi with full strength, reference to phi may be eliminated by summing over e and ..mu.. in all final states.

A conceptual design report is given for 400 x 400 GeV proton-proton storage rings. A facility is described with twice the energy capability of the recently proposed ISABELLE. The basic accelerator lattice was modified so that the circumference of the magnet rings can be increased substantially without an increase in the transition energy. Each 400 GeV ring uses superconducting magnets of the type described in the ISABELLE Proposal, but energized to 50 kG. Other technical features are not significantly different from the 200 GeV design, and are described. The beams will collide in six interaction regions where up to 60 m of space is available for the installation of experimental equipment. The research possibilities that are provided by the increased center-of-mass energy are briefly described. Finally, a cost estimate of 238 million dollars for the research facility is outlined. This is nearly 40% more than the cost of the 200 GeV ISABELLE, but this facility would provide twice the energy available for exploring new regions of high energy physics.

A special vacuum version of an adiabatic surface thermometer for automatically controlling a critical temperature-time cycle of a production vacuum-brazing process is described. This thermometer touches the surface and uses a differential thermocouple and heater to measure surface temperature without heat flow, thereby minimizing large errors caused by conduction losses common to conventional spring-loaded thermocouples. Some important advantages of our design for vacuum chamber use are: continuous operation at 850/sup 0/C, intermittent operation to 1300/sup 0/C, no outgassing or plating-off at high temperature in a vacuum system, and an integral connector that permits easy replacement of broken probes.

Dynamic tests and modeling studies were made on the chemical-energy-storage portion of an electrical energy conversion and storage system proposed for leveling the load of an electric utility company. The concept utilizes off-peak power to produce hydrogen by electrolyzing water, storing the hydrogen as iron-titanium hydride, FeTiH/sub x/, and subsequently releasing the hydrogen to a fuel cell where the reaction with air generates electrical power. The hydrogen storage portion of the system was tested on a small scale using a 6-in.-diam by 30-in.-long test bed containing 84 lb of FeTi alloy. Hydrogen reacts with this alloy at ordinary temperatures, with the release of heat, producing the hydride FeTiH/sub x/; and hydrogen is released by heating the hydride to decompose it. In the six hydriding-dehydriding cycles that were studied, the times that hydrogen flow rates of 40 to 10 standard liters per minute (SLPM) could be sustained were determined. Water temperatures of 30/sup 0/C and 50/sup 0/C were used; and the terminal hydrogen pressures used were 500 psia during hydriding and about 16 psia during dehydriding. Under these conditions the dynamic working capacity of the test bed was 1 lb of hydrogen as the composition varied between FeTiH/sub 0.175/ and FeTiH/sub …

This is a report of the sixth quarter's work on the web-dendritic ribbon growth process at the University of South Carolina. The goal of the program is to develop a multivariate semi-empirical computer model for use in understanding the web-dendritic process and defining the basic limitations of the process with particular regard to the growth rate and width. A brief description of the work carried-out and the results achieved during the past quarter are given.
