Exact calculations of nuclear-recoil energies from prompt gamma decays resulting from neutron capture
The results of an accurate determination of the recoil spectrum from (n, ..gamma..) reactions in molybdenum are presented. The recoil spectrum has been calculated from nuclear level structure data and measured branching ratios. Angular correlations between successive gammas have been accounted for using the standard theoretical techniques of Racah algebra and the density matrix formalism.

Automatic voltage-imbalance detector
A device is described for indicating and preventing damage to voltage cells such as galvanic cells and fuel cells connected in series by detecting sequential voltages and comparing these voltages to adjacent voltage cells. The device is implemented by using operational amplifiers and switching circuitry is provided by transistors. The device can be utilized in battery powered electric vehicles to prevent galvanic cell damage and also in series connected fuel cells to prevent fuel cell damage.

Selective emitter. Task II topical report for radiative-cooling materials
The theoretical basis of the selective emitter is that, if a material emits only in the 8-13 micron interval, it will absorb only in the same interval. After a survey of several candidate materials, the silicon oxynitride system was found to have better optical properties than previously used materials as well as economic feasibility, and efforts to acquire a sample are described. Other promising materials are described: polyvinylidene fluoride (Tedlar), silicon monoxide, silicon dioxide, and silicon nitride. (LEW)

Development of marketable solar assisted heat pumps. Phase II. Summary report, technical results
A water source heat pump has been designed that is capable of operating over the range from 40 to 110/sup 0/F entering water temperature and has a heating coefficient of performance greater than six in the upper portion of this range. A computerized heat pump balance program was written to allow the performance of either a water-to-water or a water-to-air heat pump to be predicted in either the heating or cooling mode. A detailed program description, flow charts, and sample outputs are appended. The balance program was used to specify components for a high efficiency water-to-water and a high efficiency water-to-air heat pump. Performance predictions for both units in heating and in cooling are included. The water-to-water and water-to-air performance predictions were compared. The water-to-air approach was clearly superior. A detailed design and layout was done for the three solar-assisted water-to-air heat pump. A horizontal configuration was chosen for marketability reasons. The design was made consistent with high quantity production equipment available in our factories and should result in the lowest possible manufacturing cost. A key question to be answered in this project is whether a reciprocating compressor can operate without damage at the high suction pressures characteristic to the …

Electron cyclotron resonant heating (ECRH) diagnostic system on TMX
The ECRH diagnostics system monitors the net power delivered to the plasma by four 200-kW gyrotron oscillators, the frequency of each gyrotron, and some operating parameters of the gyrotron power supply system. The combination CAMAC- and GPIB-based data acquisition system is under desktop computer control that provides the capability for data conversion and display. The data acquisition system is also interfaced to the main computer system that acquires and archives the data.

BX in situ oil shale project. Quarterly technical progress report, September 1-November 30, 1981
September 1, 1981-November 30, 1981, was the fourth consecutive quarter of superheated steam injection at the BX In Situ Oil Shale Project. During the quarter, 117,520 barrels of water as steam were injected into project injection wells at an average wellhead temperature of 715/sup 0/F and an average wellhead pressure of 1378 PSIG. During the same period, 148,516 barrels of fluid were produced from the project production wells for a produced-to-injected fluid ratio of 1.26 to 1.0. Net oil production for the quarter was 169 barrels.
