Patent CA-2075868-A1 (CA)
Title: Method of separating organic solvents
Inventor: KATAOKA TAKEHIKO
IPC: C07K5/075
Filed: 1992-08-12
Abstract: A?tRACT OF THE DISCLOSURE: The present invention disclose a method to separate each component from a mixed solution of organic solvents obtained during -the production of a-l.-aspartyl-L-phenylalanine methyl ester, which is useful as a sweetener, namely, amixed solution of acetic acid and toluene or a mixed solution of acetic acid, toluene and formic acid, recovering each component with a high recovery ratio with as small number of operations as possible. The method rationalizes the process and is highly valuable in practical use. When each component is separated and recovered from a mixed solution containing acetic acid and toluene as the main components, acetic acid and toluene are separated by azeotropic distillation using water as an azeotropic solvent, and. when each component is separated and recovered from a. mixed solition containing acetic acid, toluene and formic acid as the main components,(a) the mixed solution is distilled and formic acid is recovered from the top of the column and a mixed solution of acetic acid and toluene is recovered from the bottom of the column and (b) the mixed solution obtained from the bottom is distilled by using water as an azeotropic solvent and toluene is recovered from the top of the solumn and acetic acid is recovered from the bottom of the column.

Title: Multi-transmitter wide-area cellular broadcast communication system
Inventor: LEE CHONG U
IPC: H04B7/06
Filed: 1992-08-26
Abstract: MULTI-TRANSMITTER WIDE-AREA CELLULAR    BROADCAST COMMUNICATION SYSTEM            ABSTRACT OF THE DISCLOSURE   In a broadcast communication system, a plurality of transmitters are located at different locations throughout a broadcast area for separately and synchronously broadcasting a common digital communication signal at a predetermined frequency over different signal paths. and a receiver located within the broadcast area receives the common digital communication signal separately broadcast by a plurality of the trans-mitters at the predetermined frequency over different signal paths and processes the received signal to reproduce the common digital communication signal without the ef-fects of multipath and other channel distortions. The received signal is modified in relation to the broadcast signal by channel responses of the different signal paths: and the receiver includes an adaptive equalization filter for processing the received signal inversely in accordance with a collection of the channel responses of the different signal paths to reproduce the common digital communication signal without the effects of multipath and other channel distortions. The accuracy of the filter in processing the received signal in accordance with the inverse of the collection of the channel responses of the different signal paths is enhanced by adapting the filter to reproduce a predeter-mined known common digital communication signal without the effects of multipathand other channel distortions.
