    Abstract: A method of fiber formation by electrical-mechanical spinning is disclosed. A liquid starting material is fed to a rotating annular member such as a spinning cup. The liquid material is directed by centrifugal force to the periphery of the annular member where it is expelled in fibrous form. An electric charge is imposed on the liquid while on the annular member or while immediately being expelled from the annular member.

    Abstract: This invention relates to electromagnetically induced thermal activation method and apparatus for in-situ preparation of samples including zeolite catalyst. More particularly, the invention relates to preparation of samples for IR spectroscopic characterization analysis. The technique is based on electromagnetically introduced thermal treatment of a catalyst situated in a specially designed vacum cell which is housed in the sample compartment of an IR analyzer. The sample is selectively heated by adsorption of direct infrared radiation from a laser. The sample is supported on a negligible mass which preferably comprises a wire made of nichrome.

    Abstract: The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including conversion of oxygenates to hydrocarbons. The calcined, low acidity catalysts exhibit improved selectivity to certain desired products.
