Abstract: BEHIND CASING WATER FLOW DETECTION USING CONTINUOUS OXYGEN ACTIVATION                 (D#74,199-F) ABSTRACT OF THE DISCLOSURE         Measurement of the volume flow rate and linear flow velocity of undesired behind casing water flow is provided.          A well tool having a 14 MEV neutron source is used to con-tinuously irradiate earth formations behind well casing.  The continuous neutron irradiation activates elemental oxygen nuclei comprising the molecular structure of any undesired water flow to be detected.  Dual spaced gamma ray detectors located above or below the neutron source detect the decay of unstable isotope nitrogen 16 and from these indications the linear flow velocity of the undesired water flow is deduced.  By then estimating the distance R to the undesired flow region the volume flow rate V may be deduced.     I

Abstract: ABSTRACT OF THE DISCLOSURE       A power supply interruption detecting circuit which prevents an error in a write signal or sending and receiving signals of a data processing unit in the case of interruption of a commercial power supply or a power supply voltage drop resulting from an accident of other units connected to the same power supply.   An abrupt drop of the power supply input voltage is detected by comparing the voltage of a CR circuit of a small time constant with the voltage of a CR circuit of a relatively large time constant.   A slow input voltage drop is detected by comparing the voltage of the CR circuit of small time constant with a constant reference voltage.   The power supply interruption is rapidly detected in substantially a constant short time regardless of input voltage variations and the write signal or the sending and receiving signals are each clamped at predetermined logic voltage, by which sending and writing of an error signal can be effectively prevented.

Abstract: TAPERED STRAP ELEMENT FOR AN ELECTRICAL FUSE               ABSTRACT OF THE DISCLOSURE An electrical fuse is taught having a ribbon-like fuse element therein.  The fuse element has a generally uniform width along its length, but the depth of the fuse element is tapered in some regions.  Holes or openings of various shapes are disposed along the length of the fuse through the depth thereof.  The holes may be circular, triangular, or rectangular in shape and may be through a central portion of the fuse element or may comprise notches at the edges of the fuse element or both.  The depth of the fuse element may increase with longitudinal distance from a relatively thin central portion of the fuse element to relatively thick end portion thereof, or vice versa. During low current clearing, the relatively thin portion will melt first and then burns back along the tapered por-tions until the fault current is extinguished.  During high current interruption the fuse element will melt first at the notches located on the thin portion of the element and then progressively at the notches along the tapered portion of the element.  Multiple arclets are thus formed in series which merge towards each other with time.  Each arclet provides a component voltage for a composite arc voltage which limits current.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the removal of metal poisons such as nickel, iron and/or vanadium from a hydrocarbon conversion catalyst which includes the steps of contacting a regenerated sulfided catalyst with an oxygen-containing gas in a defined temperature range of from about 525°F. to about 725°F. and washing at least a portion of the metal poisons from the catalyst. A preferred wash solution is a reductive wash medium comprising a saturated, aqueous solution of SO2. The vanadium and nickel metals may be recovered from the resultant used wash solution for possible metallurgical use. The washed catalyst may also be subjected to subsequent oxidative washes such as a hydrogen peroxide wash prior to its return to the hydrocarbon conversion process.

Abstract: SOLAR ENERGY CONVERSION SYSTEM                 Abstract of the Disclosure A solar energy collection and conversion system is disclosed in which a cassegrain mirror system is rotated about a diurnal axis, which axis is adjusted for seasonal variations in the incidence of the sun's rays on the earth's surface.  Along the diurnal axis used for rotation of the collection system an elongate cavity filled with translucent or transparent fluid material is used for direct absorption of the sun's rays.  This is accomplished by providing the wall of this cavity with highly reflective surfaces so that substantially all of the incident solar energy is absorbed directly by the fluid medium and only an insignificant portion is absorbed by the cavity walls.  The fluid within the cavity may be maintained under extremely high pressures and temperatures in order to utilize this fluid as a heat storage medium.  Such heat storage is facilitated by apparatus which permits a change in the volume of the reflective cavity in response to the temperature or pressure of the fluid within the cavity.

Abstract: Abstract Apparatus for feeding flock fibers comprising an upwardly open flock-receiving hopper.  The hopper has a bottom discharge passage under which is mounted metering apparatus providing a plurality of discharge openings of controllably variable size.  An upper impeller having a plurality of downwardly angled blades is rotatably driven within the hopper passage to urge the flock fibers to fall downwardly through the discharge openings into a cylindrical pump chamber.  A lower impeller is rotatably driven within the pump chamber to sweep falling flock fibers into a pump throat in communication with a venturi flow tube through which a supply of air is passed.  The air flowing through the venturi flow tube creates suction to draw the fibers within the throat into the venturi flow tube for entrainment with the air stream.

Abstract: ABSTRACT     The conventional ignition simulator is basically used for checking and calibrating automotive ignition oscilloscopes.  It has very few circuit deviations which can easily be introduced by a switching operation so as to permit continuous control of oscilloscope and test instrument readings, for the purpose of study and analysis.  This present automotive ignition system simulator and waveform generator has a distributor in which the igniter arc dis-charge can be viewed.  The rotation of the rotor, in the distributor, is regulated by a solid state motor speed controller.  Oscilloscope waveform deviations are accomplished by means of electronic control, not faulty ignition component replacement.  Combined with an ignition oscilloscope and related test instruments, this present simulator provides a comprehensive means of analyzing ignition waveforms as well as a teaching aid for ignition system theory.
