Molding compositions for the fabrication of shaped articles having enhanced mechanical properties are comprised of (i) a polymeric matrix, (ii) an inorganic reinforcing filler material therefor, and, advantageously, (iii) a polymer/filler coupling agent, said reinforcing filler material consisting essentially of intimate admixture of enstatite and silica advantageously prepared by calcination of a...

A method of scrubbing reaction products resulting from flame burning of fuels containing impurities such as sulfur compounds, chlorine compounds, and fluorine compounds. The scrubbing is accomplished by the addition to the fire chamber of additives which bind the impurities. The additives are supplied to the burner flame by way of a gaseous and/or liquid carrier medium flow, accompanied by the for...

The present invention provides for a novel fiber-reinforced cement-like material which is characterized by having short polyvinyl alcohol fibers in an amount of at least 2 volume % based on the total volume of said material. These fibers have an elongation at break of between about 4 and 8% and a modulus of more than 130 g/dtex. A process for the preparation of said material is also disclosed.

A process is described which uses a modified double distillation cycle for rejecting nitrogen from a natural gas stream containing varying amounts of nitrogen, methane, carbon dioxide and ethane-plus hydrocarbons. The natural gas stream is fractionally distilled in the high pressure distillation stage of the double distillation cycle to provide a nitrogen overhead and a bottoms comprising carbon d...
