The disclosure is directed to an acoustical heat pumping engine without moving seals. A tubular housing holds a compressible fluid capable of supporting an acoustical standing wave. An acoustical driver is disposed at one end of the housing and the other end is capped. A second thermodynamic medium is disposed in the housing near to but spaced from the capped end. Heat is pumped along the second thermodynamic medium toward the capped end as a consequence both of the pressure oscillation due to the driver and imperfect thermal contact between the fluid and the second thermodynamic medium.

The magnet power supply for the Tandem Mirror Experiment Upgrade (TMX Upgrade) contains 24 groups of dc rectifiers that feed the water-cooled magnets. Each group consists of five or less rectifiers, connected in series. All 24 are current-regulating, using phase-controlled bilateral thyristors in the rectifier transformer primaries. The electric utility system must furnish reactive power to these phase-controlled thyristors as well as to the cmmutating diodes in the rectifier bridges.

A linear relationship represents the hydrogenation activity decay of catalysts used in four experimental runs reported previously. The weight percent hydrogen in the reactor product oils plotted against oil-catalyst contact time for experimental runs ZBB, ZBC, ZBD, and ZBE reveals a linear decay rate of 0.0083 wt% hydrogen per hour. This is one quantitative measure of catalyst activity decay. The data for the plot incorporate three different catalysts or combinations used to process a PAMCO liquid at 1500 psig, 435C and LVHST of 2 hours. The data set covers run duration of up to 120 hours of oil-catalyst contact. An air driven hydrogen compressor was installed in the Catalyst Life Test Unit to reduce the costs associated with bottle hydrogen. Minor repairs were made on the oil feed pump. Five experimental runs were made with Shell 324 NiMo/Al catalyst using two feedstocks: (1) 40 wt% EDS/EDS raw solvent and (2) 30 wt% SRC-I creosote oil. The EDS feed oil proved to be rather easily hydrotreated as evidenced by 82 to 100% nitrogen removal, essentially complete desulfurization and no catalyst activity decay during 260 hours of continuous operation. Rapid coking resulted from the highly hydrogen deficient SRC/creosote mixture. The Shell 324 …

This report presents a general analysis of personal staff functions in a congressional office. Because there is little specific information from Congress and other sources regarding staff job descriptions and because congressional office organization patterns very significantly, this report focuses on the staff functions that are common to all offices regardless of organizational structure or job title: office management; mail; projects; casework; legislation; schedulng and personal services; press and public relations; and political functions.

Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82/sup 0/F desired for these prawns, a geothermal resource having a 150/sup 0/F temperature or higher, is needed. The best estimate is that 150/sup 0/F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150/sup 0/F geothermal water.

Helium analyses have been initiated for the helium accumulation dosimetry materials irradiated in the neutron characterization experiment at RTNS-II. Analyses of the separated isotopes of molybdenum irradiated in the RTNS-I, RTNS-II, and Be(d,n) neutron fields are in progress. The emphasis during the present period was on improving the gas mass spectrometer sensitivity for these samples.

Closed-end tubes are now being prepared in-house, for use in fabricating and evaluating the FBA cell design. New perovskite-type mixed oxides are being investigated as air electrode materials and some have been identified and are being used in FBA cell test evaluation studies. Initial FBA cells have been fabricated and tested. Although their performance is below target goals, fabrication procedures for all fuel cell components have been verified for cell construction. Areas of investigation for FBA cell performance improvement have been identified and work is proceeding in these areas. Variable-length cells in the series-cell stack design have demonstrated high (85%) fuel utilization with good performance (0.57 anti V at 400 mA/cm/sup 2/ average, simulated coal derived fuel, 1000/sup 0/C).

GeoProducts Corporation and the California Department of Water Resources have jointly proposed to develop a 55 MWe power plant in Lassen County, California. The proposed power plant is unique in that it will utilize geothermal heat and wood fuel to generate electrical power, the first attempt to utilize these resources together on a commercial scale. This report identifies requirements for new environmental information that must be generated for permit applications and for preparation of environmental documents required by CEOA and NEPA; presents a schedule for generating new environmental data, for preparing and submitting permit applications, and for obtaining permits; presents a budget for permitting, licensing and environmental assessments as required by applicable laws, regulations and procedures; and investigates the step needed to qualify for a Small Power Plant Exemption by the State Energy Commission.

A catalyst for the synthesis of hydrocarbons from carbon monoxide and hydrogen composed of palladium or platinum and cobalt supported on a solid phase is disclosed. The catalyst is prepared by heating a heterogeneous component of the palladium or platinum deposited on the solid support in a solution of cobalt carbonyl or precursors thereof. The catalyst exhibits excellent activity, stability in air, and produces highly desirable product fractions even with dilute gaseous reactants. The catalyst is preferably used in dilute slurry form, which is desirable from a heat transfer standpoint.

A multicompartment photoelectrodialytic demineralization cell is provided with a buffer compartment interposed between the product compartment and a compartment containing an electrolyte solution. Semipermeable membranes separate the buffer compartment from the product and electrolyte compartments. The buffer compartment is flushed to prevent leakage of the electrolyte compartment from entering the product compartment.

We have studied Bacillus subtilis, Bacillus pumilus and Bacillus caldolyticus to ascertain the molecular mechanism of the ability to growth at high temperatures. B. subtilus wild type strains grow in minimal salts medium at a mesophilic temperature (37/sup 0/C) but not at a thermophilic temperature (56/sup 0/C). However, they do grow at 56/sup 0/C in complex rich media. Analysis of their nutritional requirements revealed that these bacteria require pyridoxine or aspartic acid and threonine to grow at 56/sup 0/C indicating that they are temperature sensitive mutants. Furthermore, mutants of B. subtilis which are able to grow on minimal salts media at 56/sup 0/C can be readily isolated. Therefore, it appears that the lack of growth of the wild type strain in minimal salts media at 56/sup 0/C is due to the instability of an anabolic enzyme. In contrast to B. subtilis, B. pumilus has never been observed to growth above 50/sup 0/C. However, our studies show that mutants of B. pumilus and B. subtilis which grow at 68/sup 0/C can be easily isolated. The isolation of such mutants strongly supports the idea that one gene can determine the ability to grow at extreme temperatures.

Addition of metal to plastic layers in some direct drive laser fusion targets is needed to reduce electron induced fuel preheat. A plasma polymerization coating system was constructed to produce a metal seeded polymer by adding an organometallic gas to the usual trans-2-butene and hydrogen feedstocks. Since organometallic gases are highly reactive and toxic, safety is a major concern in the design of a coating system. Our coating apparatus was designed with three levels of containment to assure protection of the operator. The gas handling system has redundant valves and was designed to fail safe. Several sensor controlled interlocks assure safe operating conditions. Waste materials are collected on a specially designed cold trap. Waste disposal is accomplished by heating the traps and purging volatile products through a reactor vessel. The design, operating procedure, and safety interlocks of this novel coating system are described.

This report discusses the MX Intercontinental Ballistic Missile (ICBM),which is designed to be the most lethal strategic ballistic missile in the world. The missile was developed by the U.S. Air Force to augment the capabilities of the presently deployed ICBM force, which together with Submarine Launched Ballistic Missiles (SLBMs) and manned strategic bomber aircraft form the triad of U.S. strategic nuclear offensive forces.

During the last six months, performance testing of waste/cement pellets was continued. These evaluations included leachability tests and compressive strength tests of cold soil/cement pellets of various compositions. Fractional leach rates (g/cm/sup 2//day) after 21 months of testing were, in all cases < 1 x 10/sup -5/ g/cm/sup 2//day (Mound Acceptance Value). Based upon these recent data, the pressed waste/cement pellets appeared to be a suitable matrix for the immobilization of low-level transuranic wastes. The installation of the Carver custom pellet press was completed. Plutonium-238 contaminated (< 100 nCi/g) ash/cement pellets were produced at a rate of 360 pellets/hr. Pellets of two different compositions were produced, 50% ash/50% cement and 65% ash/35% cement. The compressive strength of sample pellets was slightly lower than expected. Static MCC-1 leachability testing as well as long-term radiolysis testing of sample pellets are scheduled.

The permitting process is reviewed. The environmental data requirements are presented for: air resources; vegetation and wildlife; geotechnical environment; surface waters; cultural resources; public health, industrial hygiene, and noise; land use and socio-economic factors; and scheduling and budgets.
