Title: Metering separator for determining the liquid mass flow rate in a gas-liquid oilfield production stream

Abstract: "METERING SEPARATOR FOR DETERMINING THE LIQUID MASS FLOW RATE IN A GAS-LIQUID OILFIELD PRODUCTION STREAM"                     ABSTRACT OF THE DISCLOSURE           The separator accepts both the casing annulus and tubing production streams issuing from an in situ combustion project pro-duction well.  Most of the gas in the flow is first separated from the liquid and solids, by centrifugal action.  This gas is removed from the separator.  The remaining mixture is accumulated until a pre-determined weight is in hand, at which point the accumulated batch is dumped.  The time taken to accumulate the batch is noted.  Com-putational elements then determine the mass flow rate of the dumped mixture.          The separator comprises an upright cylindrical vessel having tangential inlet means at its upper end and a dump outlet at its base.  The gas-liquid-solids production mixture enters the vessel chamber through the inlet means and is spun, to form a central gas vortex and an outer, downwardly descending liquid-solids mixture.  The separated gas leaves the chamber through an outlet line at the upper end of the vessel.  The liquid-solids mixture accumulates as a batch in a collection zone in the lower end of the vessel chamber.  Elements are provided for maintaining a generally constant backpressure in the vessel, to provide the drive needed for discharging the batch of liquid-solids mixture therefrom.  A pair of pressure sensors are positioned in the chamber, one at the base of the chamber and the other part way up its length.  These pressure sensors are connected with a unit adapted to measure the pressure differential and emit a signal indicative thereof.  When the pressure differential signals reach a pre-determined value, a dump valve in the outlet line is opened by elements responsive to the signals.  When the pressure differential signals reach a pre-determined minimum value, the dump valve is closed.  A computer is utilized to calculate the liquid mass flow rate from the weight and time measurements.

Abstract: ABSTRACT  A continuous process for the synthesis of unsymmetrical, substituted diarylamines in which a mixture of a soluble catalyst dissolved in a substituted phenol and a primary arylamine are reacted at an elevated temperature and pressure in a reactor to form a reaction mixture comprising a substituted, unsymetrical diamine, a diphenylamine, catalyst, unreacted primary arylamine, unreacted substituted phenol, water and ammonia, which is flash separated in a flash separator to a vapor phase containing the unreacted primary arylamine, unreacted substituted phenol, water and ammonia components while substituted, unsymmetrical diamine and diphenylamine components are maintained in a liquid phase. The vapor phase is removed from the flash separator, subjected to reduced pressure, cooled and fed into a second flash separator where the water and ammonia components are flash separated to vapor phase while the unreacted primary arylamine and unreacted substituted phenol are maintained in the liquid phase. The unreacted primary arylamine and unreacted substituted phenol are then removed from the second flash evaporator and recycled in the continuous process.

Abstract: DNA SEQUENCING     ABSTRACT OF THE DISCLOSURE    To sequence long strands of DNA, cloned strands having lengths longer than 100 bases are, in one embodi-ment, marked on one end with biotin. These strands are divided  into 4  aliquots  and  each  aliquot:  (1)  is uniquely chemically treated to randomly terminate the strands at the non-biotinylated end at a selected type of  base;  and  (2)  is  moved  continuously   by electrophoresis through a different one of  four identical channels.  In the one embodiment, the strands are randomly terminated at a selected base type and they are moved into avidin, which  due to high affinity, combines with the biotin marked ends of shorter strands before the longer strands are fully resolved in the gel.          The  avidin is marked with fluorescein,  the strands are  scanned and  the signals are decoded.   In another embodiment,  the strands are synthesized, with termina-tion at a selected base type and marked either by the above method or by ethidium bromide.

Abstract: FAULT DETECTION ARRANGEMENT FOR A     DIGITAL CONFERENCING SYSTEM            Abstract The disclosure relates to error/fault detection in signal processing systems such as those employed in a time division multiplex conferencer.  The digital message samples (of the conferees) and the accompanying parity bits are delivered to a signal processor e.g., a binary arithmetic adder.  The adder sums the message samples and this sum is coupled to a first parity tree, which in response thereto generates a first parity bit.  The carries generated by the summing operation are coupled to a second parity tree along with the message parity bits and the second parity tree generates a second parity bit therefrom. The first and second parity bits are compared and if they differ a fault exists.  Corrective action is taken immediately--the faulty conference "leg" is removed from the conference connection without affecting the remaining legs in the conference or any other conference.
