Abstract: The present invention is directed to an apparatus and method which provide repeatable control of speech input to a microphone via audio feedback to a user. In this manner, repeatable and simultaneous control of microphone positioning and speaking volume is obtained. In a first embodiment, a microphone in the mouthpiece of the handset is used to detect sounds emanating from the mouth and audio feedback is provided through a speaker in the handset earpiece to ensure the microphone is positioned correctly for the application. In alternate embodiments, feedback is provided based upon voiced and unvoiced amplitudes of the input speech to obtain more optimal results.

Abstract: A catalytic process is provided for upgrading a hydrocarbon feed stream containing pseudocumene together with a fraction of close boiling hydrocarbon compounds having a normal boiling point in a temperature range of about 320.degree. F. to about 365.degree. F. comprising contacting such hydrocarbon feed steam in the presence of hydrogen with a catalyst comprising AMS-1B crystalline borosilicate molecular sieve whereby such close boiling hydrocarbon compounds are converted to compounds having a normal boiling point below a temperature of about 300.degree. F., and fractionating the effluent product stream.
