  • Patent number: 4885182
    Abstract: A method of and apparatus for extracting the fruit meat section of a fruit, and subsequently separating and removing the sectional membranes and seeds from the fruit meat section to produce free juice and an abundance of unruptured juice sacs. In one embodiment of the present invention, whole fruits are fed into a dual turret extraction apparatus that includes a plurality of matched resilient cups for holding the fruit. After the fruit is cut in half, the halves are indexed through successive coring and reaming stations. The coring station includes a coring element that cleanly extracts a hemisperical section of fruit meat from the peel. The reaming station includes a reaming element that gently removes any fruit meat remaining within the peel. The fruit meat sections are then fed into rag separator apparatus that uses a rotating screen drum and a counterrotating shaft having striker bars projecting radially therefrom to strip the juice sacs from the sectional membranes.

  • Patent number: 4874536
    Abstract: A solid water-soluble cake comprising: from 20% to 90% sodium alkyl sulfate (AS)/sodium alkyl benzene sulfonate (LAS), co-surfactant having a 1:1.5 to 1.5:1 ratio and from 0.5% to 25% by weight magnesium chloride. One key advantage is that the cakes of this invention have a more constant dissolution rate over a wider range of water temperatures than comparable cakes made without the MgCl.sub.2. The cakes are used in automatic toilet bowl cleanser dispensers.

  • Patent number: 4863619
    Abstract: Polymeric soil release agents that have high viscosities when molten are difficult to process. Certain organic materials can be added to such agents to lower the viscosity and improve processing. Examples of such organic materials include fatty acids, some nonionic ethylene glycol derivatives, polyethylene or polypropylene glycols and their short alkyl chain ethers, certain polyhydroxy and alkyl ether solvents, and aryl ethers of propylene glycol.

  • Patent number: 4859388
    Abstract: An improved, continuous airlaying apparatus for making airlaid articles such as discrete absorbent fibrous cores for catamenial napkins and disposable diapers and the like having high structural integrity, and good edge definition. The articles are airlaid in discrete cavities as they pass through a deposition zone of the apparatus, and are compacted a predetermined amount prior to their being removed from their respective deposition cavities. An exemplary mechanism for effecting the compacting comprises a lugged cylinder having circumferentially spaced lugs which are configured and pitched to mesh in a quasi gear-like manner with the deposition cavities.

  • Patent number: 4846587
    Abstract: A bag comprised of flaccid material and having an improved integrally formed carrying handle which supports the weight of one or more articles contained within the bag with minimal discomfort to the supporting portion or portions of the user's body. The bag includes an uppermost flap containing the improved integrally formed carrying handle. The handle is provided by making a continuous curvilinear slit in the flap, the ends of the slit comprising a pair of inwardly. open arcs. The uppermost ends of the inwardly open arcs are inwardly extended until they transition into a centrally located, upwardly concave arc which connects the two inwardly open arcs to one another.

  • Patent number: 4834735
    Abstract: An absorbent article wherein the deposition region of its absorbent member comprises a storage zone and an acquistion zone having a lower average density and a lower average basis weight per unit area than the storage zone. The acquisition zone is positioned toward the front of either the absorbent member or the absorbent article so that the acquistion zone may most effectively and efficiently rapidly acquire discharged liquids. The absorbent member also comprises a mixture of hydrophilic fibrous material and discrete particles of absorbent gelling material to enhance the absorbent capacity of the absorbent member.

  • Patent number: 4835001
    Abstract: Dough compositions that are baked to form pastries, biscuits, shortbreads and shortcakes having improved tenderness are disclosed. This benefit is achieved by incorporating into the dough a fat product comprising sucrose fatty acid esters having at least 4 fatty acid ester groups and optionally other fat ingredients. The fat product has a penetration between about 120 mm/10 and about 350 mm/10 at 70.degree. F. (21.degree. C.) and a yield point between about 500 dynes/cm.sup.2 and about 10,000 dynes/cm.sup.2 at 70.degree. F. (21.degree. C.). The dough is made by a process employing a low shear method of mixing.

  • Patent number: 4826499
    Abstract: An integral disposable absorbent garment, such as a disposable diaper or an incontinent brief, having a chassis means and an improved fastening system in a waist portion of the chassis means. The fastening system comprises a laterally displaceable elastic member, which is affixed to the chassis means, and a fastening means, such as a refastenable tape, joined to said elastic member. Thus, the fastening means, rather than being affixed to the garment in a fixed relation, is instead laterally displaceable in relation to the balance of the garment. The improved fastening system provides the garment with a better fit, improved adjustability, and the capability of being able to be pulled on or off the wearer without unfastening.

  • Patent number: 4820447
    Abstract: Disclosed is a mild skin cleansing soap bar composition comprising: (1) 50-90% soap, and (2) a hydrated cationic polymeric skin conditioner. The physical composition of the bar is such that the hydrated polymer is substantially uniformly distributed and well incorporated in the soap. The hydrated cationic polymer improves the mildness of the soap bar to a level approaching that of bars made with very mild synthetic surfactants, while maintaining the desirable physical characteristics of a pure soap bar without the polymer.

  • Patent number: 4813539
    Abstract: A carton for a roll-type product which is dispensed by unrolling, withdrawing and separating a piece of the product from that remaining on the roll. The carton has a projection extending inwardly from each end wall, into the core of the product, to prevent the roll from being withdrawn from the carton during use. The end walls have an inner end flap with an orifice and an overlapping end flap with the projection hingedly attached to it and extending through the orifice. The projection has a central section which is generally triangular with the apex located distally of the hinge. Wing sections flank the central section and these are adapted to be folded back from the central section as the projection is inserted through the orifice, to form the projection into an open-sided generally pyramidal shape which is deflectable towards the product core following insertion.
