Characteristics of chars produced by pyrolysis following rapid heating of pulverized coal. [104 references]

Description: A 5.08-cm id pyrolysis furnace has been used to study pyrolysis following rapid heating of size graded pulverized coal particles as a function of isothermal pyrolysis time (0.018 to 1.025 second), particle size (50 to 181 ..mu..m), and parent coal (three lignites). The following experimental conditions were kept constant: Coal feed rate approximately equal to 0.5 g/min; volumetric flow rate of nitrogen temperature = 808/sup 0/C, and pressure = atmospheric. Under these conditions the heating rat… more

Magnetic behavior of current-carrying type-II superconducting cylinders

Description: The theoretical magnetic behavior of current-carrying superconducting cylinders in the presence of applied axial fields is investigated. An attempt is made to systematize the complex behavior by carefully accounting for critical current, surface pinning, and surface pitch angle, and by stressing the importance of the magnetic history of the sample. A differential equation is developed relating the thermodynamic field H(B) to the cylinder radius rho. This equation, is readily integrated numerica… more

Investigations of several interference effects in high frequency plasmas of analytical importance

Description: Investigations of the extent to which certain inter-element or interference effects occur in a radiofrequency-excited inductively coupled plasma (ICP) are reported. Under conditions normally employed for analytical purposes, it is shown that: (a) two solute vaporization interferences often observed in flames are eliminated or reduced to negligible proportions in the plasma; (b) increasing concentrations of an easily ionizable element (Na) up to concentrations of 6900 ..mu..g/ml exerted an unusu… more

Theory of the temperature dependence of positron bulk lifetimes-implications for vacancy formation enthalpy measurements via positron experiments

Description: Temperature dependent effects, which may have a bearing on determinations of vacancy formation enthalpies in metals by positron annihilation, have been observed in certain metals. These effects have been observed to occur both at temperatures below those at which positron annihilation is most sensitive to equilibrium vacancies and at temperatures well within the vacancy-sensitive region. The effect of thermal lattice displacements on positron lifetimes in metals was investigated to help underst… more

Phase I of the automated array assembly task of the low cost silicon solar array project. Annual technical report. Motorola report No. 2258/4

Description: Work performed to analyze, both technically and economically, the state of technology readiness for the automated production of solar cells and modules is compiled and reviewed critically. The long-term objective solar module characteristics include a selling price of less than $.50/peak watt and a mean-time-before-failure (MTBF) of 20 years in any terrestrial environment. While efficiency is important to attaining the cost goal, it is a most significant factor in array economics; accordingly, … more

Solder fused interconnections in multilayer circuits

Description: A new solder fusion process has been developed for production of multi-layer cables and multilayer printed wiring boards. The multilayer process consists of three steps: (1) the photo-etching fabrication of the basic flexcircuit, (2) the lamination bonding of several flexcircuit layers together, and (3) solder fusion interjoining of the exposed lands to provide electrical continuity. Solder fusion is the unique feature of the process. In the solder fusion process the multilayer assembly is neve… more

Filter testing and development for prolonged transuranic service and waste reduction

Description: The life of High Efficiency Particulate Air (HEPA) filters used in transuranic service is influenced greatly by the gaseous and particulate matter to which the filters are exposed. The most severe conditions encountered at Rocky Flats are at the ventilation systems serving the plutonium recovery operations in Bldg. 771. A project of filter testing and development for prolonged transuranic service and waste reduction was formally initiated at Rocky Flats on July 1, 1975. The project is directed … more

Thin rod heat flux transducer positioned in the earth having a uniform temperature gradient: a closed form solution

Description: Signals from a thin rod heat flux transducer will be measured and translated into a geothermal heat flux. A mathematical temperature solution has been developed for an idealized thin rod positioned in an infinite solid with a uniform temperature gradient. This solution approximates the actual temperature to be encountered in the transducer when located in a drillhole. The solution is a closed form type for a thin rod wherein radial temperature differences are small compared to axial ones; the s… more
