A revised program plan is presented for developing an electric vehicle incorporating a flywheel regenerative power system with design considerations and goals for safety and for vehicle body construction using lightweight fiber-reinforced composite material. Schedules are included for each of the major steps in the program. (LCL)

Simultaneous measurements of enthalpy, specific volume, temperature, and electrical resistivity for lead and uranium were measured. From the measured data, estimates of the bulk modulus and sound velocity in these metals are made. (GHT)

The Gunn-diode microwave cavity instrument is a self-contained (the vacuum pump is external) microwave spectrometer for the specific detection and monitoring of ammonia gas in air. A solid state microwave source is used together with a high-Q resonant microwave cavity which is both the frequency selecting device for the source and the sample container through which the sampled gases pass. The ammonia absorption transition at 23,870.1 MHz is monitored continuously with this instrument. The monitoring frequency is stable to one part in 10/sup 9/ so that the system only responds to NH/sub 3/ absorption--there are no known interfering gases. The instrument was designed for simple operation and easy calibration. Except for the calibration procedure, the instrument operates automatically from turn-on. A four-digit readout is supplied on the front panel and it reads the concentration of ammonia directly in parts-per-million over a range of from 0.00 to 20 ppM. A 0 to 10 volt output is also available at the rear panel for recording data on an external recorder.

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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.

Most of the large U.S. utilities were surveyed by telephone and mail on questions concerning nuclear power plant siting and nuclear energy centers (NECs). The main purpose of the survey was for guidance of ERDA's NEC program. The questions covered the following topics: availability of sites; impact of environmental and other restraints; plans for development of multi-unit sites; interest in NEC development; interest in including fuel-cycle facilities in NECs; and opinions on the roles desired for the state and Federal governments in power plant siting. The main conclusion of the survey was that, while many utilities were considering multiple-unit sites of 2 to 5 units, none were planning larger energy centers at the present time. However, several expressed interest in NECs as a long-range future development.
