Abstract: ABSTRACT          PURIFICATION OF PHENOL WITH REDUCED ENERGY CONSUMPTION         Phenol (10) produced by the cleavage of cumene hydroperoxide is chemically treated with a base (12) such as a polyamine, is optionally then treated with an acid or acid anhydride (15) such as phthalic anhydride, is then steamed distilled (12) to remove a lites fraction as a water azeotrope (21) and the bottoms (34) of the steam distillation are vacuum distilled (35) to recover high purity phenol (36) as an overhead,  The overheads (21) of the steam distillation are condensed (22) and may be phase separated (23) into an aqueous phase (25) and organic phase (24), with the aqueous phase (25) mixed (26) with an organic solvent (27) which preferentially dissolves benzofuran impurities. This mixture is phase separated into an organic solvent phase (30, 130) and a recycle aqueous phase (31).  Alterna-tively, the entire condensed overheads (21) may be ex-tracted (146-151 and 153) with organic solvent.  In some forms, the organic solvent phase (130) is washed with aqueous base (142) to remove phenol and impurities and the organic solvent (127) is regenerated for again mixing with the aqueous phase.  In other forms the organic solvent is a portion (152) of the high purity phenol product (36).  This treatment and careful control of the chemical treatment to minimize formation of benzofuran impurities reduces the steam consumption of the steam distillation step, thereby producing high purity phenol with reduced energy consumption.

Abstract: ABSTRACT OF THE DISCLOSURE        A core barrel flushing device and method is disclosed particularly for flushing drilling fluid, mud and other undesirable material from a pressure core barrel downhole at existing conditions and pressure.  The flushing device (F) comprises an outer barrel attachable to the drill string and core barrel, and an inner barrel within the outer barrel.  A sealed chamber (C) within the outer barrel contains a piston and flushing medium (M) displacable from the chamber (C) and into the core barrel during forceful displacement of the piston following actuation of the flushing device.  Actuation of the flushing device is initiated by means (B) passed down the drill string into engagement with actuating means allowing displacement of the piston and flushing medium from the chamber into the core barrel.  Tripping means are also disclosed responsive to the final movement of the piston to actuate, and seal the flushed pressure core barrel and core sample  therein downhole.

Abstract: Abstract of the Disclosure A phase synchronizing circuit has a phase locked loop including a first phase comparison circuit to which a predetermined input signal is supplied, a voltage controlled oscillator (VCO) for producing an oscillation output the frequency of which is controlled by the output from the first phase comparison circuit, and first frequency dividing means having at least a first frequency divider to divide the output frequency of VCO.  The phase synchronizing circuit further includes second frequency dividing means for dividing the output frequency of VCO, a second phase comparison circuit for comparing the phase of a first clock signal which is lead from first dividing means, with that of a second clock signal which is lead from second dividing means, and a controlling means for controlling the first frequency divider and second phase comparison circuit so as to synchronize phases of first and second clock signals.  The controlling means controls the frequency dividing ratio of first frequency dividing circuit according to the phase difference between first and second clock signals in such a way that the frequency dividing ratio becomes one of 1/N, 1/(N+1) and 1/{[N+tN+1)]/2} wherein N is a positive integer.  Phases of first and second clock signals can be synchronized accurately.

Abstract: "Abstract of the Disclosure"    A stabilized fumigant composition comprises an aqueous solution containing up to about fifty percent by weight of a solute which comprises ammonia, hydrogen sulfide and carbon disulfide.  Elemental sulfur can also be a component of the solute.  One preferred composition comprises a solution wherein the molarity of hydrogen sulfide is about 1.5 times the molarity of carbon disulfide, and is about one-half the molarity of ammonia, and wherein the molarity of sulfur is about 1.6 times the molarity of carbon disulfide.    The composition decomposes in a soil environment to form sources of available plant nutrients, including ammonia, hydrogen sulfide and sulfur, and carbon disulfide which inhibits nitrification and decreases the nematode population. nutrient content can be enhanced by the addition of, for example, ammonia, ammonium nitrate, urea and mixtures thereof to the formed composition.    The composition can also be decomposed by dilution or heat application, or both, to yield its components for non-soil fumigation uses.
