Granted: 1986-08-19
Abstract: ABSTRACT A method of well logging in petroleum exploration and apparatus for use in the method as described. An improved magnetometer is disposed in a well bore to provide indications of the distribution, filimentation, and distortion of a controlled current flow within adjoining strata of interest. The current flow is excited by a distant alternating source located at the surface or at other boreholes, and perturbations in the current flow and accompanying magnetic field caused by the electrical characteristics of the adjoining strata are registered by the magnetometer.           The magnetometer comprises a pair of elongated U-shaped cores of laminated, high-permeability metal, with portions of each core being surrounded by a sensing coil. The coil output is fed to surface equipment for detection and analysis.

Abstract: CRYOGENTIC REFRIGERATION SYSTEM              WITH LINEAR DRIVE MOTORS                    ABSTRACT      In a cryogenic split Stirling refrigerator, the compressor and displacer are driven by linear drive motors.  Each compressor linear drive motor has a plurality of radial permanent magnets 44, 46 mounted to each compressor piston 22, 24.  A tapered collet 56 expands an expanding sleeve 42 against the magnets and compresses a sleeve 38 against the piston.  A housing 34 hermetically seals the gas about the armature and supports the coil assembly 76, 78.  The displacer drive motor includes an axial permanent magnet 202 mounted to the displacer drive piston 192.  It is surrounded by a housing 210 which hermetically seals the spring volume surrounding the magnet.  The drive coils 216, 218 are supported on that housing.  The coils are surrounded by flux returns 222, 224 which can be adjusted to minimize radial forces on the drive piston.

Abstract: ABSTRACT     A valve body includes a chamber for the flow of fluid between an inlet and outlet thereto.  A valve member, such as a ball valve member, is positioned in the chamber for rotation between an open position and a closed position to open and close the chamber.  An actuator is rotatable about an axis coaxially aligned with the valve member axis.  A lower end portion of a valve stem is connected to the valve member and an upper end portion is connected to the actuator.  The valve stem upper end portion is displaced angularly from the valve stem lower end portion.  The valve stem lower end portion has an axis aligned with the rotational axes of the valve member and the actuator.   The axis of the valve stem upper end portion is positioned in spaced parallel relation to the axes of the actuator and the valve member.  Thus, the upper end of the valve stem is offset from the axis of rotation of the actuator so that the valve stem upper end portion orbits about the actuator axis as the actuator is rotated to move the valve member between the open and closed positions. The valve stem is sealed by a bent bellows.  A bearing assembly rotatably supports the upper ends of the valve stem and bellows in the actuator. The bearing assembly maintains the valve stem upper axis parallel to the actuator axis so that the valve stem upper end portion remains freely rotatable relative to the actuator as upward pressure forces are applied to the valve stem.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of and apparatus for effecting rapid, reliable and risk-free, pressure-tight connection of a plasma generator to a reactor, such as a shaft furnace for metal oxide reduction.  First electrical contact means arranged on a plasma generator, substantially enclosed by a cover, automatically connect the plasma generator to stationary second contact means when the plasma generator is moved by remote-control to a fully installed operating position from a partially installed sealing position in which the plasma generator has its front end partially inserted in the reactor tuyere and seals the reactor.  A remote-contro-lled valve, which seals the reactor from the surroundings when the plasma generator is in an outer completely retracted position, is opened once the plasma generator is in its sealing position, after which the plasma generator is moved to its operating position.  Remote-controlled locking bars are caused to press and lock the plasma generator to the reactor in order to effect pressure-tight connection, and at the same time the locking bars connect the plasma generator to the return conductor to the current source, thus providing extra security against the current circuit being connected before a pressure-tight seal has been achieved.

Abstract: ENERGY CONVERSION SYSTEM WITH FERMENTATION                  Abstract A  system  is  disclosed  for  converting  one  form  of energy into an alternate form of energy by means of a low temperature process.  A liquid flow loop with two vertical columns  that  are  interconnected  at  the  top and bottom circulates a fluid.   A convective flow of this fluid is established by heating the fluid in one of the columns and cooling  the  fluid  in  the  other  column  to  establish  a weight  differential  between  the  fluid  in  the  two columns.  An electric generator is placed on this loop so that, as the fluid flows through the loop and through the generator,   electrical   energy   is   generated.     This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen.  The gasses so generated are used to increase the rate of flow of the fluid, and consequently the rate of electric energy production.   The apparatus incorporates  a  fermentation  process  to  produce  Carbon dioxide gas and heat energy.   In one embodiment,  these gasses are injected into the rising column of the fluid to increase the weight differential between the fluid in the two  columns  and  enhance  the  convective  flow  of  that fluid.   These gasses, which contain chemical energy, are then removed from the  loop at  the  top of this  column. Alternatively,  the  gasses  can  be  accumulated  at  high pressure, and the pressure used to inject a volatile fluid into the loop.

Abstract: ABSTRACT     In order to join concrete floor elements to walls such that expansion gaps are preserved between the two, thrust studs must be employed. Since the round cross sectional shapes of the steel bars and sleeves can transmit only relatively modest loads to the surround-ing concrete without causing damage, the steel bars are joined together by connecting plates, and the sleeves are joined together by other connecting plates, provid-ing increased bearing area. In this way the thrust stud can transmit high loads to the concrete elements with-out causing damage. A front plate attached to the sleeves facilitates installation of the thrust stud in the concrete form used for producing the concrete elements, since said plate can be nailed to said form.

Abstract: IMPROVED SYNTHESIS OF MOLYBDENUM/ALCOHOL COMPLEXES USEFUL AS EPOXIDATION CATALYSTS                  (D#80,316 -F) ABSTRACT OF THE DISCLOSURE           Molybdenum/alcohol complexes useful as epoxidation catalysts made by reacting an oxygen containing molybdenum compound with a monohydric alcohol and ammonium hydroxide at elevated temperatures are described.  It has been discovered that complexes with a molybdenum content of 2 to 6.5  wt.% can be made if a small amount of ammonium hydroxide is in cluded in the reactant mixture.  The amount of ammonium hydroxide depends on the ratio of alcohol to molybdenum compound.  If this ratio is correct, the resulting complex solution is stable and easily filterable.  Molybdenum tri-oxide and 2-ethyl-1-hexanol are the particularly preferred reactants.         Alternatively, molybdenum/alcohol complexes useful as epoxidation catalysts can be made by reacting oxygen-containing molybdenum compounds with a monohydric alcohol and water at elevated temperature.  It has been discovered that complexes with a molybdenum content of 3 to 10.5 wt.% can be made if a small amount of water is included in the reaction mixture.  The amount of water depends on the ratio of alcohol to molybdenum compound.  If this ratio is correct, the resulting complex solution is stable and is easily fil-terable.  Ammonium heptamolybdate or ammonium heptamolybdate tetrahydrate or ammonium dimolybdate and 2-ethyl-1-hexanol are the particularly preferred reactants.

Abstract: Abstract:   A differential thermal wattmeter of the type disclosed in US. Patent 4,045,734 is modified to remove undesirable in-phase a.c. ripple at the fundamental frequency in the feedback path.  This result is achieved by a closed loop system in which the in-phase signal in the feedback path is detected and driven to zero by injecting sufficient signal in opposite polarity into the feedback path to cancel the ripple.  The advantages are reduction of error and the ability to use standard, low cost components.
