Title: A process for recovering and purifying unreacted acrylonitrile
IPC: B01D3/10
Filed: 1987-07-30
Granted: 1991-12-27
Abstract: Excess amounts of a pure form of acrylonitrile are reacted with other reactants in the production of various compounds such as 2-acrylamido-2-methyl propane sulfonic acid. Accordingly, large amounts of acrylonitrile remain unreacted and present with other contaminants. The present invention is directed toward the purification of such unreacted acrylonitrile and the purified acrylonitrile obtained from such a purification process. The purification is carried out by treating the unreacted acrylonitrile with a base and removing salts formed. The treated material is fed to a heat exchanger which heats the material preferably under vacuum to about 120 DEG  F. and provides a heated fluid material. This heated fluid material is pumped to a lower area of a distillation tower which is maintained under vacuum and includes a plurality of distillation trays. Purified acrylonitrile has a lower boiling point and is drawn toward the top of the tower by vacuum and removed whereas the remainder of the material which includes contaminants has a higher boiling point and falls to the bottom of the tower. This bottom portion is removed and recycled to the heat exchanger. The purified acrylonitrile removed from the top of the tower by vacuum is capable of, and sufficiently pure for, reuse in the formation of other compounds such as 2-acrylamido-2-methyl propane sulfonic acid. The process provides purified acrylonitrile while avoiding undesirable polymerization. The purified acrylonitrile obtained from the proces and 2-acrylamido-2-methyl propane sulfonic acid produced with the purified acrylonitrile lack undesirable water insoluble polymers and copolymers and have improved and unexpectedly superior storage stability.

Title: Extended errors correcting device having single package error correcting and double package error detecting codes
IPC: H03M13/19
Filed: 1988-04-29
Granted: 1993-07-07
Abstract: A digital error detection and correction apparatus for correcting n-bit data words comprising a field of n-r data bits and a field of r error-correcting-code-ECC bits according to an error correcting code. The n-bit data words are organized in packages of b bits, and the invention is capable of correcting one package having suffered at least one hard failure and a single soft error being located in a different package. The apparatus of the invention involves an error correcting code which gives a first syndrome when the data word has suffered a first error coming from at least one error in a first package and a single error in a second package different from the first package, which also gives a second syndrôme when the data word has suffered a second error coming from at least one error in the above first package, and a single error in a third package. The error correcting code is such that the equality of the above first and second syndromes results in the equality of the first and second errors. The apparatus of the invention further includes means (24) for storing the syndrome of a first data word v, and means (24) for adding the syndrôme a second data word v min , the latter data word v min  being generated from the first data word v by means of an "invert write" and an " invert read" procedure. The above addition allows the masking of the single soft error. The invention further includes means (20) for determining whether the result of the above addition provides a syndrome characterizing a single package syndrôme, in order to determine the number of the package having suffered at least one hard error, and means (21, 22, 50-XX) operative in response to said determination for directly locating the positions of the errors, either soft and hard, in order to restore the originally stored data word.

Abstract: An arrangement to remove drift and wow and flutter in a tape recording comprising recording a control signal tone derived from a reference clock (159) in a dedicated control channel or embedded in a signal channel. The control signal on playback (151) is compared to the reference signal in an up/down counter (172) and the difference is used to correct the speed of the tape drive. The drift corrected control tone signal is connected through a programmable RAM delay (154) and a latch (179) to a D/A converter (156). The delayed analogue control signal and the reference signal are limited then connected to phase comparator counter (158) which is triggered by the leading edge of the reference signal and read by the leading edge of the squared control signal to measure the time delay between them as a number of RAM (154) samples (N) and subsamples (n). The measured time delay is used to advance or retard the Read address (155) relative to the Write address in the RAM delay (154) where unit change in the tap address (N) is equal to 20 musec in the example. The remaining time delay (0-19 musec is connected to a phase delay circuit (178) effective to delay readout from the RAM via the latch (179) in one microsecond intervals in the example.
