摘要： A nonadiabatic calorimetric technique useful broadly for quantifying the reaction kinetics of thermally unstable solids is based on the distinguishing mode of establishing, under near steady state conditions, a thermal gradient across a reaction sample contained between monitored hot and cold surfaces, stepwise or rampwise increasing the temperature of the hot surface, and quantifying the maximum temperature that is withstood by the sample at the inception condition of a thermal runaway reaction. The critical hot surface temperature recorded by the experiment is a function of the cold surface condition, i.e., the applied thermal gradient. At least two critical hot surface temperatures, which are required for calculations, are generated by repeating the experiment under differing cold surface conditions. Solution of the steady-state differential equation describing the system, utilizing the experimental data, yields the general kinetics of the decomposition reaction of the tested solid. These thusly known kinetics allow prediction of the unsteady-state adiabatic or nonadiabatic thermal decomposition of the solid for any product geometry and initial condition.

摘要： A system for determining the fractional capture efficiency of filters includes two filters having substantially the same capture efficiency connected in series. A steady, controlled flow of ultrapure water and a colloidal silica suspension is directed through both filters, with respective stages of the flow upstream of the upstream filter, between the filters and downstream of the downstream filter, directed to respective non-volatile residue monitors. Each residue monitor produces a digital output representing the non-volatile residue concentration at its respective stage. A microprocessor receives the digital outputs and generates respective residue values indicating residue concentration in parts per billion. The three residue values are used to characterize the residue by proportion of the colloidal silica suspension to other residue components, and to calculate filter capture efficiency with respect to the colloidal silica. In an alternative embodiment, a valve selectively, individually and alternatively directs each one of the flow stages to a single non-volatile residue monitor. As a further alternative, when the concentration of dissolved impurities is known to be small as compared to the colloidal silica concentration, filter efficiency can be determined using a single filter and two non-volatile residue monitors.

摘要： A treatment for finely divided silica reinforcing fillers is provided which comprises heating the silica filler in the presence of a fluoroalkyl-functional diorganopolysiloxane. The treated fillers are especially compatible with fluorosilicone gums, and fluorosilicone rubbers made using said fillers exhibit improved mechanical properties, especially tear strength and compression set.

摘要： Nitrogen oxides, such as nitric oxide with hydrogen separated by acid electrolytes, are reacted at porous catalytic electrodes in a configuration to generate electrical energy and selectively reduce the nitric oxide to ammonia, hydroxylamine and other products. Product distribution and reaction rate can be controlled with electrocatalyst, external load and other parameters. The electrogenerative process is applied to the reduction of other gases.
