Abstract: METHOD AND APPARATUS FOR MAKING A        NONWOVEN FABRIC                  ABSTRACT OF THE DISCLOSURE       Method and apparatus for making a nonwoven fabric wherein a first group of filaments are projected in a longitudinal direction into the nip of a pair of nipped and moving collecting surfaces in such a manner that the filaments fold into and are captured and held by the nip with spans of the filaments lying in the plane of the nip and at the same time projecting a second group of filaments in a longitudinal direction toward one of the collecting surfaces at a location spaced from the nip. The second group of filaments impinges on an impact plate positioned above the collecting surface and is pulled off the impact plate by the moving collecting surface, this causing the filaments in the second group to extend primarily in the machine direction. The moving collecting sur-faces carry the groups of filaments into contact with each other to form a nonwoven fabric which is subsequently bonded in a conventional manner to form a finished fabric.  In the finished fabric the filaments from the first group will for the most part extend across the fabric while the filaments from the second group will for the most part extend along the fabric to give a fabric having a stretch on the bias.

Abstract: ABSTRACT    OF   INVENTION      The present invention relates to new graft polymers obtained from lignosulfonate and d monomer selected from acrylic acid, methacrylic acid and mixtures thereof at a pH between 1.5 to 4 in the presence of an initiator.    The new graft polymers have been found to be very useful as soil conditioners and as binding reagents for agglomerating single particles of particulate materials.    The graft polymers according to the invention are obtained in the form of an aqueous solution, which may be transformed into a powder by spray drying.   As soil conditioners they may be applied by spraying, alone or admixed with fertilizers or pesticides and also combined with the operation of planting and soil stabilization.

Abstract: IMPROVED VENT ASSEMBLY                  ABSTRACT OF THE INVENTION A vent assembly for use in a tubing string located down-hole in a borehole.  The vent assembly is moved to the open posi-tion by a fishing tool attached to a slick line and run downhole through the tubing string into engagement therewith.  The vent assembly includes an elongated, annular piston which slidably and sealingly engages the inside peripheral wall of a housing.  The housing has radial ports which are covered by spaced seals located on the annular piston.  One of the seals is larger in diameter than the other, thereby presenting different surface areas to the bottomhole fluids of the borehole within which the assembly is located.  A sliding valve element underlies the annular piston and covers a relatively small bleed port so that when the valve element is moved by the wireline actuated tool to uncover the bleed port, the pressure differential across the housing is equal-ized. The sliding valve element is engaged by the wireline fish-ing tool and oved uphole to uncover the bleed port and thereafter, moved further uphole to open the vent port.
