Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to injection molding and parti-cularly to a melt transfer system for stack molding. According to the invention, a novel combination of known melt flow control valve units are arranged and operated to control the flow of pressurized melt from the stationary platen adjacent the molding machine to a manifold in the center moving platen.  One control valve unit is located in the stationary platen in align-ment with another control valve unit located in the moving platen.          When the moving platen is in the closed position adjacent the stationary platen, the gates of the two control valve units abut and when the valve pins of the two control valve units are actuat-ed to the open position, pressurized melt will flow through the gates from the stationary platen to the moving platen.  The hot runner passage extends from the molding maching through the con-trol valve unit located in the stationary platen.  Through the gates into the control valve unit located in the moving platen, and then through the manifold system to the cavities located on opposing faces of the moving platen.  In a second embodiment, a first cavity is located between the above two gates, and a third control valve unit is located in the moving platen in abutting alignment with the second control valve unit and its gate extends to a second cavity of the opposite face of the moving platen.

Abstract: POWER STEERING VALVE AND METHOD OF MAKING THE SAME   ABSTRACT OF THE DISCLOSURE     An improved power steering valve has a cylindrical sleeve which circumscribes an inner valve member.  The valve sleeve has relatively short inner grooves which extend in opposite directions from a central portion of the sleeve.  Although the inner grooves can be sequentially formed with an end mill, a pair of the axially extending inner grooves are advantageously formed at the same time by simultaneously cutting away material from the inside of the valve sleeve with a pair of rotating end mills.  When a pair of axially extending inner valve grooves are being formed by the use of two end mills, the end mills extend into the valve sleeve from opposite axial ends of the valve sleeve.

Abstract: ABSTRACT OF THE DISCLOSURE     A nonwoven fabric having alternating stripes of high fiber density and low fiber density is made in such a manner that the high fiber density stripes run across the fabric and maximize the cross direction strength to a point that the cross direction/machine direction strength ratio approaches unity.  This advantageous and desirable characteristic can be achieved by hydroforming a card web, by disposing the carded web on a relatively fine mesh screen and placing a finger-like striping bars over the web with the axis of the bars at 90° to the card web's general fiber orientation.  Water was then sprayed over the assembly with sufficient force to rearrange the fibers in the web thereby producing the nonwoven fabric of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for recovering a magnesium carbonate of high purity from an aqueous magnesium hydroxide slurry.  The slurry contains at least one percent of magnesium hydroxide and includes water, magnesium hydroxide, and impurities normally associated with magnesium hydroxide slurries.  The method involves carbonating the slurry with sufficient carbon dioxide to dis-solve a substantial proportion of the magnesium hydroxide therein as magnesium bicarbonate, and continuing carbonation until a solution saturated with magnesium bicarbonate is formed.  A portion of the magnesium bicarbonate is converted to a crystalline magnesium carbonate.  Substantially all the dissolved calcium is precipitated so that the slurry contains dissolved magnesium bicarbonate, a crystalline magnesium carbonate precipitate and a calcium carbonate precipitate. The solids are then separated from the magnesium bicarbonate solution, the solution is decarbonated, for example by heat or vacuum, and hydrous magnesium carbonate is separated from the aqueous phase.
