Abstract: ABSTRACT OF THE DISCLOSURE          A meter and a method are provided for measuring the com-position and flow rate of a coal slurry and other similar mixtures.          The meter is a waveguide through which the mixture flows.  Microwaves are propagated in the waveguide from a transmitter probe.  A detector probe spaced from the transmitter probe receives signals from the microwaves.  Those signals are processed to determine a characteristic frequency of the waveguide or the wavelength of the propagating micro-wave, which are related to the composition of the mixture within the waveguide.  A second transmitter and detector pair determines these prop-erties for another portion of the waveguide.  Differences in the fre-quencies resulting from inhomogenuities in the mixture are cross cor-related to determine the flow rate of the mixture.

Advantageously, different compartments have different numbers of perforations, to allow the active material to be released in a controlled manner over a relatively long period of time.  The substrates advantageously comprise paper or nonwoven fabric laminated with thermoplastic film, the two substrate layers being bonded together in a grid pattern by heat-sealing of the thermoplastic films.

Abstract: Abstract of the Disclosure Discrete bodies of glass-forming raw materials are formed  by  agglomerating  techniques  such  as  briquetting These bodies are preheated or prereacted using waste heat from the fusion furnace.  The hot glass bodies are charged to a refractory hearth heated to a temperature  substan-tially above the temperature at which the glass product becomes fluid.   The discrete bodies absorb heat,  form a liquid phase and lose their  morphology.   The  hearth  is structured so that the liquid phase flows through it in a thin layer entraining any unreacted/unmelted material.  As the molten material flows it  is further heated and the reaction is completed.  Molten glass product can be drawn from the hearth in a surprisingly short time after charg-ing the heated discrete bodies to the hearth.

Abstract: METHOD AND APPARATUS FOR FOR PRODUCING          AVERAGE MAGNETIC WELL IN A REVERSED FIELD PINCH          ABSTRACT OF THE DISCLOSURE        A magnetic well reversed field plasma pinch method and apparatus produces hot magnetically confined pinch plasma in a toroidal chamber having a major toroidal axis and a minor toroidal axis and a small aspect ratio, preferably less than 6.  A reversed magnetic field pinch current channel within the plasma and at least one hyperbolic magnetic axis outside substantially all of the plasma form thereby a region of average magnetic well in a region of nested closed magnetic surfaces surrounding the plasma current channel when the magnetic field component in the direction of the hyperbolic magnetic axis is also made to be substantially less than zero in the vicinity of the hyperbolic magnetic axis.  The magnetic well reversed field pinch is operated so that reversal of the safety factor q and of the toroidal magnetic field takes place within the plasma, and the plasma so produced closely approximates known theoretical stability conditions.          The nested closed magnetic surfaces define an elliptic magnetic axis preferably substantially coplanar with the hyperbolic magnetic axis, which preferably lies close to the plasma surface to deform the surface toward the toroidal magnetic axis.  The well is preferably formed substantially at a magnetic flux surface within the plasma where the absolute value of q is greater than its absolute value anywhere within the magnetic flux surface on which magnetic field reversal occurs.  The well-producing plasma cross section shape is produced effectively by an exterior shaping shell assembly.   The plasma is formed inside a vacuum chamber and an electrically conducting shaping shell assembly, whose non-circular poloidal cross section imparts the desired shape to the plasma.  The shape of the plasma may be maintained and/or adjusted by means of electrical currents driven through appropriately distributed external conductors.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus is described for produc-ing viscous petroleum from a subsurface formation.  The apparatus includes a generally horizontal cased well through the subsurface formation with injection and pro-duction tubings within the well.  The casing is perforated and the inner tubings carry a movable packer and a rotat-able agitator.  The method comprises injecting a heating and drive fluid for moving heated viscous petroleum through the perforations in the casing and into the well for production to the wellhead.  Production is monitored for the ratio of produced packer fluid and viscous petro-leum.  Based on that ratio, the packer is moved within the casing to positions along the horizontal well to maximize production of petroleum.  The rotatable agitator assists in removal from the well bore of formation solids produced with the viscous petroleum.
