Abstract: Method Of and Apparatus For Reducing Back Corona Effects Abstract An apparatus for reducing back corona effects while charg-ing high resistivity dust or the like in a corona field, includ-ing a corona discharge electrode, a passive electrode and a screen electrode, the screen electrode being positioned between the discharge electrode and the passive electrode.  The screen electrode is positioned more closely to the passive electrode than the discharge electrode and is supplied with an electrical potential which is of the same polarity as and a fraction of the magnitude of the discharge electrode relative to the pass-ive electrode.  Gas having entrained therein the particulate material, which is to be removed, flows between the screen and discharge electrode and thence to a particular material col-lection stage.  The space between the screen and corona dis-charge electrode remains essentially a unipolar ion field, while ions of the opposite polarity originating at passive electrode due to back corona are collected by the screen elec-trode.

Abstract: ABSTRACT OF THE DISCLOSURE           A floatator for use in benefication, coal dressing, wet refining and so forth, incorporating a surface flotation technic.  The flotator has a funnel-shaped liquid cell having a bottom of an area smaller than that of the top opening.  A bubbling device is constituted by an upper sleeve partly immersed in the liquid contained by the cell, a lower sleeve disposed coaxially with the upper sleeve and fully immersed in the liquid.  The upper end of the lower sleeve is spaced by a predetermined distance from the lower end of the upper sleeve to form therebetween a spaced region located at a small depth from the liquid surface.  The bubbling device further has a rotary blade unit constituted by upper and lower blades separated by a flat partition plate.  The rotary blade unit is adapted to rotate around the common axis of the upper and lower sleeves, and has a thickness or axial height substantially equal to the aforementioned predetermined distance in the spaced region, and is located such that the flat partition plate is located at the heightwise mid point of the spaced region.  The floatator further has a liquid surface stabilizer constituted by a frusto-conical member disposed around the bubbling device and adapted to deflect the liquid downwardly.  Further, provided are a feeding passage having a feed gate opening in the bottom area of the cell and a discharging passage having a discharge gate spaced from both of the feed gate and the lower edge of the liquid surface stabilizer so as to avoid the "short-circuiting" of the liquid.

Abstract: ABSTRACT OF THE DISCLOSURE          A hand-held carrier for a pair of skis and a pair of poles includes a pair of confrontable clamping members hingedly interconnected at their lower ends.  The members when in confrontation define a pair of adjacent ski-receiving openings (each for receiving the mid-section of a ski) and a pair of adjacent pole-receiving openings, (each for receiving the mid-section of a pole).  The upper ends of the clamping members are releasably interengaged and are latched together by a latching means.  A pivotable handle is mounted on one of the clamping members and may be swung as to allow a reduction in the space required by the carrier when loaded onto a car rack, thereby permitting the use of a greater plurality of carriers and supported skis and poles on a particular car.  When the skis and poles are clamped in their openings, their longitudinal axes extend in parallelism and perpendicular to the longitudinal axes of the clamping members with the skis and poles being disposed in a side-by-side relationship in a single plane.  The assembly may be conveniently carried by the handle and may be conveniently secured relative to a carrier atop a vehicle. Each ski-receiving opening is constituted by one portion for accommodating a ski of a more narrow width and another portion for accommodating a ski of a more wide width according to the desires and needs of the particular owner.

Abstract: Abstract Synthesis reactor and processes A reactor for catalytic gas reactions such as synthesis of methanol or ammonia comprises at least one cylindrical catalyst bed having a height not greater than half its over-all diameter and defined on its underside by a grid supported by a dished plate hav-ing peripheral mechanical connection to a downward extension of the bed wall.  Preferably there are several such beds and an indirect heat exchanger upstream of the downstream-most bed.  The reactor is suitably 5 - 10 m in diameter and is especially for use at under 120 bar abs. in an integrated process for producing methanol and ammonia.          Referring to figure 1, outer vessel 10 contains three small catalyst beds 12A, 12B, 12C each bounded on its underside by a grid 16 supported via radial webs 20 by convex-upward dished plates 22 secured to vessel 10 at 24.  Between beds 12A, 12B and 12C is a quench gas sparger 28.  Under bed 12C is a chamber from which axial tube 26 leads to heat exchanger 40.  The outlet of heat ex-changer 40 leads via inner axial tube 42 to large catalyst bed 14 in which further reaction takes place.

Abstract: METHOD FOR IMPROVING DISSOLUTION EFFICIENCY IN GAS ABSORPTION AND LIQUID EXTRACTION PROCESSES                 ABSTRACT OF THE DISCLOSURE This invention is a method for improving dissolution efficiency in processes in which a feed fluid is introduced to a zone where it is con-tacted with a liquid solvent for preferentially removing a component of the feed and where part of the solvent so contacted undergoes transfer into the feed fluid to saturate the same.  It has been found that such transfer significantly impairs dissolution efficiency.  In accordance with the invention, an amount of the above mentioned solvent is added to the feed fluid being introduced to the contact zone, the solvent being added in an amount sufficient to effect reduction or elimination of the above-mentioned transfer.  Preferably, the solvent is added to the feed fluid in an amount saturating or supersaturating the feed fluid under the conditions prevailing in the contact zone.

Abstract: Abstract of the Disclosure A stabilized sleeve arrestor is described as well as the method of mounting the same on a high pressure pipeline.          A cylindrical sleeve is first placed on the line pipe and has upper and lower openings formed therein.  The ends of the sleeve are sealed with plastic tape or the like and reinforcing straps are mounted  thereon.  A urethane elastomer filler material  is forced through the bottom opening to fill the annular space between the sleeve and the exterior surface of the pipe.  The material  is pumped into the annular space until it flows from the upper opening.          After curing, the reinforcing straps are removed.  The filler material causes the sleeve to adhere to the pipe to prevent longitudinal displacement of the sleeve should a crack occur.          The filler material also prevents corrosion between the sleeve and the pipeline.
