Abstract: ABSTRACT OF THE INVENTION       Hydrogen sulphide in the waste water from a coal gasification installation is subjected to an oxidising treatment in the presence of the very fine-grain residual coke which, being washed out of the product gas, is sus-pended in the waste water, the residual coke particles thus serving as a catalyst. When using air for the oxidation treatment, with the usual period of treatment, it is possible to achieve virtually quantitative conversion of the hydrogen sulphide to sulphate. If the solid particles are to be removed from the waste  water by a flotation step, the flotation operation and the oxidising treatment can be performed simultaneously in a common apparatus.

Abstract: PROTECTOR UNIT FOR TELECOMMUNICATIONS CIRCUITS            Abstract A protector unit for protecting tip-and-ring conductors of a telephone loop includes a pair of protector assemblies which are supported within a common housing.  A voltage protection subassembly is connected electrically to a ground subassembly for causing current associated with excessive voltage surges to be conducted to ground.  Each protector assembly includes a heat coil subassembly mounted on a dielectric half-base, together with a central office pin.  The heat coil subassembly includes a line pin, an eyelet, disposed concentrically about the line pin and releasably secured to one end of the line pin in an initial position by a fusible bonding material, and a resistance wire wound about the hub of the eyelet.  One end of the wire is welded to the eyelet, and the other end is welded to the central office pin to establish a direct current path between the line pin and the central office pin.  The two base halves and the components disposed thereon are held in mated position theretogether by the protector housing.  A spring between a cup of the voltage protector subassembly and the housing maintains the voltage protection subassembly in engagement with the eyelet. Also, the spring is effective when current flow exceeds a predetermined level that is sufficient to cause the fusible bonding material to melt to cause the eyelet to be moved to a position where it engages a portion of the grounding subassembly to establish a fault current path to ground potential.

Abstract: ABSTRACT         The fluidic oscillator consists of a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance.  The inertance is a conduit interconnecting two locations of a chamber on each side of a working fluid jet issuing into one end of the chamber, the inertance conduit serving to transfer working fluid between the two locations.  Through one or more output orifices located approximately at the opposite end of the chamber, the fluid exits from a chamber exit region which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid.  The flow pattern in the chamber and particularly the vortex in the chamber exit region provide flow aspiration on one side and surplus of flow on the opposite side of the chamber, which effects accelerate and respectively decelerate the fluid in the inertance conduit such as to cause reversal of the vortex after a time delay given by the inertance.  The vortex in the chamber exit region will thus cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream our spray pattern whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector as well as the dynamic pressure component, both directed radially from the vortex.  By changing these parameters by suitable design measures and operating conditions and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be readily controlled over large ranges.

Abstract: SCANNING ANTENNA WITH AUTOMATIC      BEAM STABILIZATION       ABSTRACT OF THE INVENTION      A external feedback network for decreasing variations in a beam painting angle of a scanning antenna array.  A dedicated aperture manifold is integral with the aperture of the scanning antenna and provides a signal which represents the beam pointing angle.  The signal is detected, decoded, and coverted into digital data for averaging and processing by a CPU.  The processed data is then compared with a value stored in memory and any difference forms the basis of a correction signal.  For application to a microwave landing system, the corrrection signal is used to adjust the start/stop time of the scanning commands of the antenna to remove the error without modifying the beam steering algorithm.  A space-coupled monitor may also be used independent of the feedback network to provide an alarm in response to any failure of the dedicated aperture manifold, the automatic stabilization circuitry or the array system.

Abstract: ABSTRACT OF THE DISCLOSURE     Dry comestibles, such as cereal products and baked-type goods having an L-aspartic acid sweetening derivative distributed substantially uniformly throughout the comestible as a substituted for sugar or other sweeteners, are obtained by combining the L-aspartic acid sweetening derivative, a pH adjuster, water, and the remaining dry ingredients of the comestible to form a dough, extruding the dough through an extruder die plate, cutting the extruded product into pieces, and optionally reducing the moisture content of the pieces by conventional means like drying or toasting.          The most feasible method of combining the ingredients is to separately feed:  a) an aqueous solution of the sweetening deriva-tive having a pH adjusted to about 1.0-7.0, preferably 2.0-3.0, and b) a preblended mixture of the remaining dry ingredients to the extruder wherein they are admixed to form a dough.  Decomposition of the L-aspartic acid sweetening derivative during processing is minimized by controlling the pH of the sweetener solution, and the exposure time of the sweetener to high temperatures throughout the process for producing the dry comestible.  The extruded dry baked comestibles are highly palatable, do not look sugar coated, do not contain localized concentrations of the L-aspartic acid sweeten-ing derivative and are shelf stable for extended periods of time.

Abstract: Title of the Invention POWER SUPPLY THERESHOLD ACTIVATION CIRCUIT Abstract of the Disclosure An improved tristate enable circuit is described for activating a tristate enable gate to maintain the high impedance third state of a common bus tristate output device during "power down" and "power up" transitions of the common power supply Vcc.  The enable gate circuit element tends to turn off at a voltage level Vcc2 generally greater than the voltage level Vcc3 at which the tristate output device circuit elements turn off.  As a result the high impedance state may be lost during "power down".  A threshold activation circuit is coupled to the enable gate for activating the enable gate when the threshold activation circuit senses a higher common power supply voltage level Vcc1.  The threshold activation circuit operatively activates the enable gate over a voltage range from Vcc1 to a lesser common power supply voltage level Vcc4.  Component values are selected for relating the voltage levels so that Vcc1 >  Vcc2 and Vcc3 > Vcc4. As a result the turn off or circuit elements is sequenced by the threshold activation circuit.

Abstract: DOUBLE RESONATING BEAM FORCE TRANSDUCER           WITH REDUCED LONGITUDINAL PUMPING       Abstract A double resonator beam force transducer configured to minimize longitudinal pumping by making the beams vibrate sym-metrically.  This can be accomplished by making the boundary conditions of the beams symmetrical or, if the boundary condi-tions are nonsymetric, then by biasing the beams inwardly or outwardly to compensate for the nonsymmetrical boundary condi-tions of the beams.  In the nonsymmetrical case where the beams would bow outwardly at their fundamental resonant frequency or an odd overtone thereof, an inward bias is provided to minimize longitudinal pumping.  In the nonsymmetrical case where the beams would bow inwardly at an even overtone of the fundamental resonant frequency, an outward bias is provided to minimize longitudinal pumping.  The inward or outward bias is provided in various embodiments by bowing the beams inwardly or outwardly, placing masses on the inner or outer edges of the beams, or tapering the inner or outer edges of the beams so that the width of the beams increase toward their midpoints.

Abstract: Abstract of the Disclosure A method for predicting the likelihood of encountering oil or gas deposits below a location.  A temperature at a known depth at the location is compared to a temperature representa-tive of the average temperature for that depth within the geographical area in which the location is situated.  If the temperature at the location is less than the average tempera-ture, it is likely that an oil or gas deposit is present at the location at a depth below the known depth.  If the temperature at the location is greater than the average temperature, then it is likely that no oil or gas deposit is present at the location at a depth below the known depth.  Alternatively, geothermal gradients are employed in a similar method for predicting the likelihood of encountering oil or gas deposits below a location.
