Abstract: ABSTRACT OF THE DISCLOSURE      Compositions of matter comprising a thermoplastic elastomeric blend of a polyolefin component, an isobuty-lene-backbone elastomer component, and a copolymer compo-nent of ethylene and an unsaturated ester of a lower car-boxylic acid.  Useful in the preparation of film, molded and extruded articles.  The incorporation of an ethylene copolymer component, such as ethylene vinyl acetate, ethy-lene methyl acrylate, etc., results in compositions with the advantages of elastomer modified polyolefin blends, but which exhibit lower melt viscosity and improved pro-cessability.

Abstract: ABSTRACT OF THE DISCLOSURE    A stitch holder is provided which takes no part in forming of stitches but which is adapted to serve the sole purpose of holding, during temporary interruption of a knitting operation, the front stitch row of a knitted work which has already been formed by a separate circular knitting needle.  The stitch holder includes an elongated flexible main body which is adapted to support a circular row of already knitted stitches.  A rigid tip is directly fixed at one of its ends to one end of the main body.       A block member is provided with a first through hole for directly receiving the other end of the main body, and with a second through hole arranged side-by-side with the first through hole, the second through hole being so sized as to allow passage there-through of the rigid tip, the block member being slidably positionable at any part of the rigid tip or of the main body, for adjustment of the diameter of the stitch holder.  Thus, the front row stitches on the stitch holder can be prevented from becoming unravelled.  In addition, the front row stitches on the stitch holder can be prevented from being locally stretched, with the result that a regularly cylindrical form of the article being knitted can be maintained.

Abstract: ABSTRACT OF DISCLOSURE      A hydrometallurgical process is provided for the recovery of molybdenum values from a molybdenum disulfide concentrate containing copper.  The process comprises forming an aqueous slurry of finely divided molybdenum concentrate with an alkali metal compound selected from the group consisting of carbonates and hydroxides of alkali metals, and pressure leaching the slurry in the presence of oxygen at an elevated temperature and pressure for a time sufficient to effect conversion of the contained molybdenum values to alkali metal molybdate and provide a residue containing copper oxide or basic copper carbonate from which copper is later recovered.  The molybdenum values are recovered from solution by solvent extraction and the solvent thereafter stripped of the molybdenum as ammonium molybde-num using ammonium hydroxide.  The molybdenum is recovered as crystals of ammonium molybdate by crystallization, e.g., by evaporating the stripping solution.

Abstract: ABSTRACT OF THE DISCLOSURE     A  method is disclosed of manufacturing a piston having a  skirt  on which are formed a  plurality  of  bearing surfaces, each bearing surface being at a predetermined axial position on the skirt,  being spaced outwardly of the  skirt to a required radial dimension and extending around  the  skirt  with  a  required   circumferential dimension.   The  method comprises forming the  bearing surfaces in at least two stages.   First a plurality of projections  are  formed on a skirt of the piston  with each  projection being at an axial position in which  a bearing  surface or surfaces are to  be  located.   The radial and/or axial dimension of the projection exceeds the  required corresponding dimension or dimensions  of the  bearing  surfaces.    A  second  step  then  forms bearing surfaces of the required dimensions.   A second form  of  piston  is formed with  cylindrical  portions which  are alternately offset to one side or  other  of the  piston axis to form,  one each side of the piston, alternate  projecting  bearing  surfaces  and  recessed skirt portions.

Abstract: IMPROVED STRENGTH AEROSOL DOME              ABSTRACT OF THE DISCLOSURE This relates to an improved aerosol container of the type wherein the dome is formed separately from the body and is secured to the body by a conventional double seam.  The aerosol container is improved by squeez-ing the double seam radially inwardly so that it is, in effect, necked in and may also be tilted to correspond generally to the dome profile.  In the utlimate condition the upper part of the body is also tilted radially inwardly and the chuck wall upper portion contacts the dome above the annular countersink completely to close the counter-sink.  The container need not be an aerosol container, but may beneficially have not only the double seam joining the top end to the body radially inwardly offset or necked-in, but also if the bottom of the container is separately formed from the body, the double seam joining the bottom to the body should also be radially inwardly offset or necked-in so that bodies of adjacent containers may be in touching relation, thus requiring less material for a container and at the same time assuring a tight package. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: METHODS OF PRODUCING PLASTIC-COATED METALLIC   MEMBERS AND PRODUCT PRODUCED THEREBY       Abstract A priorly used drop wire having a single layer of PVC insulating compound, containing a relatively-expensive epoxy additive, extruded over a spaced pair of conductors, having relatively rough surfaces, is replaced with drop wire having less-costly, relatively-smooth, drawn, conductors onto which spaced, unplasticized particles of PVC resin are coated and the portions of the particles contacting the surfaces of the conductors are melted, caused to undergo controlled degradation and adhere to the surface of the conductor, and thus form a relatively-stable, texturized, discontinuous coating of adhesion sites on the surfaces of the conductors with interdispersed portions of the surfaces being exposed.     Over the precoated conductors, a composition containing a plasticized PVC resin may be extruded to form an insulating covering having a relatively-stable, controlled degree of adhesion to the adhesion sites and the interdispersed, exposed surfaces of the conductors.     A precoated metallic member having a texturized, discontinuous coating of degradated, unplasticized plastic adhesion sites formed on a selected portions of the surface of the metallic member may be used as an article of manufacture onto which an adherent coating of compound containing plasticized plastic may be molded to make other items such as plastic-coated fencing material or aluminum siding.

Abstract: ABSTRACT An absorbent structure designed for use in absorbent pads such as diapers is disclosed.  According to a first aspect of the invention, absorbent pads are provided which comprise at least two layers of cellulosic fibers (fluff) of different densities or average pore size ranges.  When the absorbent structure is incorporated in a diaper, the lower density element extends to the full length and width dimensions of the normal absorbent component of the diaper.  The higher density element lies beneath at least a portion of the lower density element. According to various embodiments of the present invention, it can run as a strip from the target zone to the back waist of a diaper, it can run along a central portion extending the whole length of the diaper, or it can underlie the entirety of the lower density element.  The higher density element (or the element having a lower average pore size) wicks waste fluid from a lower central portion of the diaper, and thereby transports the fluid upwardly and also transfers it to the lower density element (or the element of greater average pore size).  According to a second aspect of the invention, which may be incorporated with the first aspect just described, a portion of superabsorbent material is placed beneath the higher density layer, (or layer of lower average pore size), such that an additional reservoir for absorbing waste fluid is provided.
