Abstract: TITLE         HELICALLY SEAMED TUBING WITH APPARATUS AND METHOD OF MAKING SAME     ABSTRACT      A thin perforate, hellically wound welded edge tubing is used as a filter core for a roving wound filter.  The slightly roughened external edges of the spirally formed welded joint greatly adds to the ability of securing the fiber roving to the tube and prevents relative slippage there-between.   Also, the invention comprehends an apparatus for, and a method of making the helically seamed tube by first drawing a sheet metal from a supply and raising two lateral edges thereof to form flanges. The material can be guided in a helical  path by engaging the inside of the flanges so that the trailing edge abuts the leading edge.  The abutted edges are heated so that the flanges themselves provide the filler for a weld on the exterior surface thereof.  Drive rollers are provided to move the welded tube from the welding area and to torque the tube to prevent edge separation prior to the cooling of the weld.

Abstract: A METHOD OF PREPARING PLASTER               ABSTRACT OF THE DISCLOSURE           A method of preparing plaster by brief contact between gypsum and a hot gas.  The method comprises introducing the gypsum through the axial tube of a nozzle, around which a hol-ical stream of hot gases is created, and bringing the two phases into contact in a vessel at the outlet of the nozzle.  The method of the invention makes it possible to vary the quality of plaster produced and to use either dry gypsum or dilute gypsum pastes as the starting material.

Abstract: Abstract of the Disclosure A push to start dual relay having master electrical con-tacts which are closed when a push button is depressed.  The master contacts control the power supplied to a control circuit which, in turn, controls the power supplied to two relays.  When the push button is released and either one or both relays are energized, the master contacts remain in the closed position.  When the push button is released and both relays are deenergized, however, the master contacts are allowed to open.

Abstract: CONTINUOUS-FLOW WINE CHAMPAGNIZATION PROCESS               ABSTRACT OF THE DISCLOSURE           The present invention relates to a continuous-flow wine champagnization process.      The starting fermentation broth consisting of champagne wine-stock, saccharose and yeast cells is fed into an appara-tus and passed through a yeast mass accumulated at a constant separation of yeast cells from the wine stream.  The process according to the present invention resides in that a secondary fermentation of the starting fermentation broth is effected at a temperature of up to 150°C, followed by enrichment of the re-sulting champagnized wine with biologically active yeast subs-tances.  Under the conditions of the process according to the present invention these two stages are combined.      The process according to the present invention makes it possible to intensify champagnization, improve the product qua-lity and increase, by 2-3 times, the product output per unit production area.

Abstract: Abstract of the Disclosure The present invention provides a method of and an apparatus for separating heterogeneously sized and shaped solid waste particles.  The particles are introduced into a vertical duct, under an accelerating force provided from behind the material, against a slanted wall in the duct.  Depending on the slant of the wall, particles of different sizes and shapes striking the wall will be deflected downward.  Some particles though will not receive sufficient force from the air to hit the wall and will be pulled up the duct by a vaccuum system located at the top thereof.  In this manner, materials can be separated according to their physical characteristics.  In contrast, known separating systems rely simply on the buoyancy of the different materials in order to separate them.  This means that the particles must be generally homogeneous in size and shape to achieve a proper separation.

Abstract: FOLDING FLEX TOOL BAR                ABSTRACT OF THE DISCLOSURE         A folding tool bar for agricultural implements and including a central section and outboard wing sections hingedly connected thereto for movement between extended operative lowered positions where they may follow rolling ground conditions and folded over-center raised positions to reduce transport width.  Each wing section is actuated by a two-stage hydraulic cylinder on the central section which cooperates with a crank arm on such wing section during its first stage to apply torque to the crank arm through the medium of a draw link by a pulling action in tension, assisted by a powerful camming action, the two forces serving to raise the wing so that it barely clears the ground at a small angle on the order of 5°, thereby enabling the implement to perform a turnabout motion with the tools withdrawn from the ground but with the wing remaining unfolded.  An abutment within the cylinder posi-tively terminates the first stage of operation and deter-mines the 5° elevation of the wing so that the wing section is thus positively and firmly supported during the turnabout operation and thereafter, if desired, the first stage of cylinder operation may be discontinued to restore the wing to its ground-engaging position for working the next crop row.  However, if over-center wing folding operations for transport purposes are desired, the second stage of each cylinder is employed.  Conventional hydraulically operated markers at the outer ends of the wings, and also hydraulic-ally operable assist wheels which are carried by the main tool bar section are caused to become effective at appro-priate times under the control of novel hydraulic circuitry.

Abstract: Abstract of the Disclosure Sodium sulfate is purged from a sulfur dioxide removal system involving contact of a sulfur dioxide-containing gas with a solution containing sodium sulfite to absorb sulfur dioxide from the gas.  The spent absorbing solution is regenerated by desorbing sulfur dixoide and recycled for further use.  To avoid an unduly large build-up of sulfate in the system, at least a portion of the absorbing-desorbing medium, e.g. spent absorbing solution, containing sodium sulfate and a relatively large amount of sodium bisulfite is treated to reduce the amount of water in the medium so that there is precipitated therefrom up to about 10 weight percent undissolved solids containing sodium sulfate in greater concentration than would otherwise be obtained in the absorption-desorption cycle.  The insolubles containing sodium sulfate are removed from the liquid, and the liquid can be returned to the sulfur dioxide removal system.  In one preferred aspect of the invention, up to about 75 weight percent of the entire stream of spent absorbing solution is treated to form from this solution a slurry having up to about 10 weight percent undissolved solids which are relatively rich in sodium sulfate content.  In the invention the sodium sulfate-containing solids can be separated from the liquid which is then subjected to a desorption operation to produce sulfur dioxide, and the latter operation can be conducted while maintaining at least about 25 weight percent undissolved solids in the desorption zone.

Abstract: ABSTRACT OF THE DISCLOSURE     An upper is fitted onto a last using a casing containing a first, dome-shaped diaphragm defining a first chamber with a fixed last support; a second diaphragm defining a second chamber above the first chamber; a piston/cylinder arrangement for moving the casing and first and second diaphragms between an open position and a closed position in which the casing engages the support to define the first chamber around the support and lasted upper.  By changing the fluid pressure in the first and second chambers, the upper can be drawn over the  last in a controlled manner, while avoiding the formation of pleats in the upper.  Using a pneumatic control device, first a low vacuum is drawn on the second chamber as the casing is moved to the closed position, and, before the casing reaches the closed position, the second chamber is subjected to a low super-atmospheric pressure.  Thus, the first diaphragm is stretched over the last and upper.  The casing is moved to the closed position, a high vacuum is drawn on the first chamber and the second chamber is subjected to a high super-atmospheric pressure, so that the upper is stretched around the last in pleat-free condition.
