Title: Separation of tars from carbonylation reaction  mixtures
Inventor: PORCELLI RICHARD V
IPC: C07C51/48
Filed: 1982-04-28
Granted: 1984-06-19
Abstract: ABSTRACT OF THE DISCLOSURE Tarry residues often are formed in carbonylation reac-tions, such as those in which esters or ethers are carbonylated to produce ethylidene diacetate or carboxylic acid anhydrides, such as acetic anhydride.  Such residues contain Group VIII noble metal catalysts, typically rhodium, which must be separated before the residues can be disposed of.  In the process of the invention, a portion of the carbonylation reaction mixture is flashed to a lower pressure and the resulting residues-containing liquid is extracted with solvents which preferentially remove the tars.  The tars are separated from the solvents and disposed of while the solvents are recycled for further use.  The catalyst-containing liquid is processed to remove residual solvent and returned to the carbonylation reaction.

The mechanism also includes a chassis comprising a  base, a structure for mounting the motor on the chassis with the lugs in fixed position relative to one side of the base, a pair of partitions standing upwardly from the one side of the base and spaced by a distance slightly larger than the distance between terminals of the battery to thereby define a battery compartment, and a structure for mounting each wire connector with one portion thereof urged against one lug of the motor and a second portion thereof urged to a location in the compartment for contacting one terminal of the battery.  The chassis is shaped and dimensioned to be received in the access opening of the housing with the side of the base opposite the one side constituting a generally continuous extension of the exterior walls.  Further, when the chassis is so received the motor, the fan, the connectors, and the battery compartment are positioned   within the space.

Abstract: Abstract of the Disclosure A ventricular tachycardia prediction system for use with an ECG input (10, 12, and 14) having cyclical characteristics.  The ECG input is periodically sampled during each of a plurality of ECG cycles, and signals (100, 101, and 102) representative of the ECG input for each corresponding sample time are stored (130, 132).  A high pass filter (170) adaptively filters the signals for each ECG cycle, so as to provide a filter output systematically related to the high frequency content of the ECG input.  The adaptive filter (170) produces segments which are uninfluenced by other samples so as to negate ringing.  A reference signal is provided for VT prediction.  The filter output is compared to the reference signal (200), and the prediction of ventricular tachycardia is indicated responsive to the comparison.  In one embodiment the samples are averaged (150) for a plurality of ECG cycles prior to generating the filter output.  In another embodiment, the system determines the duration (210) of the QRS portion of the ECG cycles prior to generating the filter output, provides a second reference signal for ventricular tachycardia prediction, and compares the determined duration to the second reference signal.  A prediction (220) of ventricular tachycardia is indicated responsive to the second comparison.

Abstract: METHOD FOR A NEW TYPE OF CHROMATOGRAPHY           AND DEVICE THEREFOR         ABSTRACT  OF  THE  DISCLOSURE        The present invention relates to a new type of chromatography technique, referred to as dynamic columm chromatography, for separation of one or more compounds present in a solution, which is characterized by the existence of a moving solid adsorbent bed.  According to the invention, the chromatographic system comprises a piston having at its bottom a sealing element and a longitudinal channel containing the adsorbent between two barriers and a test tube having at its bottom a multiple way valve.  By pushing the piston into the test tube, the desired eluant which was prior forced through said valve is entering under intrinsic pressure of the closed system through the channel moving the adsorbed compounds to be separated between said barriers, the  solution obtained going out through a nozzle located at one of the end parts of the piston.  The dynamic column liquid chromatography is applicable to:  silica gel chromatography, reversed phase liquid chromatography, affinity chromatography, capillary chromatography, chromato-focusing, gel filtration and ion exchange chromatography. In the dynamic column liquid chromatography, the equilibrium distribution of the compounds between the adsorbent and liquid is established very rapidly, resulting in sharp and narrow zones of the separated fractions.
