Title: Protein purification
Inventor: LAI POR-HSIUNG
IPC: C07K1/14
Filed: 1986-06-18
Granted: 1992-03-17
Abstract: "PROTEIN PURIFICATION"      ABSTRACT           Chromatographic procedures are individually and jointly applied to the rapid and efficient isolation of biologically active proteins and especially glycopro-teins such as recombinant erythropoietin present in the medium of growth of genetically transformed mammalian host cells.  Illustratively, recombinant EPO is isolated from culture fluids by reverse phase chromatography employing a C4 or C6 column and elution with ethanol. Recombinant erythropoietin may also be purified by anion exchange chromatography employing, e.g., a DEAE resin, with preliminary selective elution of contaminant materials having a lower pKa than erythropoietion from the resin under conditions mitigating against acid ac-tivated protease degradation.  Practiced serially, the two chromatographic procedures allow for high yields of biologically active recombinant erythropoietin from mammalian cell culture media.

Title: High speed auger venturi system and method for conveying bulk materials
Inventor: WYNOSKI CHARLES E
IPC: B65G53/08
Filed: 1986-10-16
Granted: 1991-06-11
Abstract: High Speed Auger Venturi System and Method for Conveying Bulk Materials Abstract An auger venturi conveying system for particulate materials includes a hopper-fed auger conveyor section for transporting the particulate material toward the discharge end of a barrel and a venturi arrangement for non-turbulent mixing of the material transported through the barrel with a pressurized gas flow.  The venturi arrangement comprises a plenum chamber surrounding the barrel of the auger conveyor section adjacent the discharge end, a venturi pipe coupled to the plenum chamber having a tapered section leading to a constriction, and a jet member within the venturi pipe coupled to the discharge end of the barrel and extending approximately to the constriction.  The outer surface of the jet member cooperates with the interior surface of the tapered section of the venturi pipe to form a narrow annular passage between the plenum chamber and the constriction of the venturi pipe.  The venturi pipe is coupled at its other end to a conduit.  A gas flow is created in the venturi pipe by introducing a pressurized gas into the plenum chamber.  The width of the annular passage is adjusted to obtain a desired pressure difference between the plenum chamber and a region of the conduit adjacent the venturi pipe.  Blowback prevention is achieved in the system by providing pressure transducers in the plenum chamber and in the region of the conduit adja-cent the venturi pipe, and a controller responsive to the signals from the pressure transducers for reducing the rotational speed of the auger conveyor if the pressure difference falls below a specified value.

Title: Filament reinforced tape
Inventor: GRUENEWALD LARRY E
IPC: G02B6/44
Filed: 1987-06-17
Granted: 1992-01-07
Abstract: ABSTRACT           This invention relates to tape, in particular, tape reinforced by means of filaments.          Individual optical fibers of fiber optic cable are generally bound by tapes or yarns.  Yarns currently used in binding bundles of optical fibers frequently attenuate the optical signal by placing high stress at various points on individual optical fibers.        This invention provides a tape reinforced by means of filaments comprising a backing and a plurality of yarns comprising a multiplicity of filaments adhered to at least one major surface of said backing by means of a layer of an adhesive.  The yarns are disposed essentially parallel to each other along the machine direction of the tape.  The yarn-bearing surface of the backing is coated with a polymeric material that both overcoats the filaments and detackifies the residual adhesive between the yarns. The yarns are preferably elliptical in cross-section, with the major axis thereof being essentially parallel to the plane of said backing.  In a second embodiment, the tape is reinforced by individual filaments adhered to the backing by means of a layer of adhesive.          One advantage of the tape of this invention is that it provides much less localized stress on optical fibers than does yarn typically used to bind optical fibers.

Title: Switched-capacitor watthour meter circuit having reduced capacitor ratio
Inventor: MILKOVIC MIRAN
IPC: G01R21/127

Granted: 1991-04-23
Abstract: SWITCHED-CAPACITOR WATTHOUR METER CIRCUIT               HAVING REDUCED CAPACITOR RATIO            Abstract of the Disclosure An electronic energy consumption measuring circuit capable of being fabricated on a single integrated circuit chip employs a switched-capacitor integrator for integrating the product of first and second voltages which are propor-tional, respectively, to load voltage and current in an electrical system to provide a measure of the energy being consumed, and a hysteresis comparator for converting the integrator output into a pulse train wherein each pulse represents a predetermined amount of energy.  The output pulses may be accumulated and displayed to provide an indication of total energy consumed.  A divider at the hysteresis comparator output enables the capacitor ratio in the switched-capacitor integrator to be reduced substan-tially so that the capacitor values are approximately the same order of magnitude.  This reduces the chip area neces-sary for fabricating the capacitors and improves the matching between the capacitors, thereby affording higher integration accuracy.

Abstract: ABSTRACT       A method for molding a cementitious composition into an article having a desired shape or configuration which comprises preparing molding means in a predetermined shape or configuration corresponding to the desired shape or configuration of the article; substantially filling the molding means with water to provide a substantial excess of that needed for hydration of the cementitious composition which will be used to make the article; introducing into the water in the molding means a dry cementitious composition in the form of finely divided particles of at least one cement binder in an amount of greater than 20 percent by weight of the composition, the major proportion of the particles having approximately the same drop rate, by pouring the composition into the water without any type of physical mixing of the cementitious composition and the water other than the mixing which occurs when the composition is poured into the water, such that the cementitious composition becomes completely hydrated by combining with a portion of the water and displacing excess water, if any, from the molding means; and allowing the hydrated cementitious composition to set or cure to a self supporting solid in the desired shape or configuration.

Abstract: Arrangement for Controlling the Position of an Aircraft Control Surface Member Abstract An arrangement for controlling the position of a movable member, especially an aircraft control surface member, includes an operational amplifier and a capacitor connected in parallel to the amplifier.  The control arrangement further includes a detector which detects the restoration of the supply of electric power following its interruption and generates a limited-duration pulse.  This pulse is then used to close a switch, which is interposed between an input terminal of the capacitor and the ground, for the duration of this pulse, so that the capacitor is charged much more rapidly than otherwise.  The output signal of the combination of the operational amplifier and the capacitor is supplied to an actuator for the movable member so that the extent of excursion of the movable member out of its desired position after the electric power supply has been restored is minimized.
