Abstract: ABSTRACT OF THE INVENTION         A mixture containing a dispersed bitumen, oil or hydrocarbon phase and a continuous aqueous phase is passed for treatment through a rotating horizontal tumbler, containing oleophilic free bodies, for the purpose of increasing the particle size of the dispersed phase and facilitating subsequent separation of the phases of the mixture.  Alternately, a mixture containing a dispersed aqueous phase and a continuous bitumen, oil or hydrocarbon phase is passed for treatment through a rotating horizontal tumbler, containing hydrophilic and oleophilic free bodies, for the purpose of increasing the particle size of the dispersed phase and facilitating subsequent separation of the phases of the mixture.          The free bodies tumbling with the mixture in the drum have affinity for the dispersed phase particles and cause an increase in the particles size of the dispersed phase of the mixture through a process of cyclic coalescence, agglutination, condensation and/or coherence of dispersed phase particles from the mixture onto the surface of the free bodies and cyclic shedding or sloughing off of coalesced dispersed phase back into the mixture.  Some mixtures that may be treated include oil sand slurries, effluent streams from a hot sands extraction plant, oil-in-water emulsions from processes that use enhanced oil well recovery, and bitumen froth.

Abstract: DUAL THRESHOLD COMPARATOR CIRCUIT                         Abstract A dual threshold comparator circuit includes a comparator amplifier for comparing an analog input signal to a threshold waveform.  The threshold waveform is generated in a circuit which includes positive and negative peak detector cir-cuits and a slope detector circuit, all of which are connected to the analog signal source.  A voltage divider is connected across the output of the positive and negative peak detector circuits. The threshold input to the comparator amplifier is connected to the common junction of first and second serially-connected impedances in the voltage divider.  At the beginning of a particular half cycle of the analog input signal, the voltage across the voltage divider is equal to the difference of the most recent positive and negative peak voltages.  The slope detector alters the effec-tive impedances in the voltage divider to cause the threshold voltage to be equal to 25 or 75% of the total difference voltage, depending upon the slope of the analog signal.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention is concerned with a process for the preparation of fiber-grade terephthalic acid from an inter-mediate stage crude dimethyl terephthalate obtained from a crude ester mixture produced by the oxidation of p-xylene and/or methyl p-toluate with oxygen-containing gases in the presence of heavy-metal-containing oxidation catalysts at an elevated temperature and under an elevated pressure, and by the esterification of the oxidation mixture with methanol at elevated temperature and elevated pressure.  The process of the invention comprises separating the resulting crude ester mixture by distillation into a methyl p-toluate-enriched fraction, a residual high boiling fraction, and also a crude dimethyl terephthalate having a limited content of the inter-mediate oxidation products and other by-products; subsequently hydrolyzing the crude dimethyl terephthalate with water at a weight ratio of the crude dimethyl terephthalate to water of between 3 : l and 0.1 ; l, and at temperatures of between 140°C. and 350°C. and under the pressure required to maintain the liquid phase to produce a reaction mixture containing crystalline fiber-grade terephthalic acid, and then recovering the terephthalic acid from the reaction mixture.  The invention enables one to produce directly from a crude DMT, a terephthalic acid, suitable for manufacturing polyester fibers, by means of hydrolysis, without the step of recrystallization of the crude DMT from methanol customary in the Katzschmann process or of a corresponding step of recrystallization of the thus-obtained terephthalic acid.

Abstract: OPTICAL TRANSDUCER ARRAY SYSTEM                       Abstract An array of optical waveguide transducers, especially suitable for use in a multi-channel hydrophone seismic streamer, contains optical wave-guides which are deformed in response to the parameter being sensed (underwater acoustic energy in the case of the seismic streamer).  Two optical signals are obtained from each transducer, amplitude modulated in opposite polarity in accordance with the parameter and returned to a collection point by way of optical signal highways, such as optical fiber waveguides.  The optical signals are time division multiplexed on the return highways by successively providing light pulses to each of the transducers upon activation of separate light sources associated therewith which are electrically activated by electrical signals propagated along a transmission line wherein the electrical signals are successively delayed. The optical signals on the return waveguides appear in time slots corresponding to the successive delays and may be sequentially interrogated at a rate compatiable with the frequency response of the array system.  At the collection point, the outputs of the return waveguides are subtracted thereby summing the optical signals from each transducer, while reducing noise introduced into the system as may be due both to variations in the amplitude of the light from the sources and mechanically due to deformation or bending of the optical waveguides other than in response to the parameter being sensed.
