  • Patent number: 5006360
    Abstract: The present invention relates to low calorie fat substitute compositions that are useful as fat replacements in low calorie foods, and as pharmaceutical compositions. Sucrose fatty acid esters are preferred low calorie fat substitutes. The compositions are highly resistant to an undesirable laxative side effect. These benefits are achieved by formulating compositions comprising a liquid polyol fatty acid polyester, at least about 10% solid low calorie fat substitute by weight of the liquid polyester, and at least about 1% of a cohesive network of polysaccharide fibrils and microfibrils, for example microfibrillated cellulose, by weight of the liquid polyester.

  • Patent number: 5002681
    Abstract: A pouched, detergent-compatible, through-the-wash, dryer-released, jumbo particulate fabric softening composition. The particle size of this particulate is from about 5 mm to about 30 mm, and preferably at least 10 mm. The low viscoisty jumbo particulate fabric softener is made to survive the wash more so than comparable smaller particulates and release more in the dryer than higher viscosity softener. The softener particulate of this invention has a low viscosity at about its melting point for good softener transferability from the pouch to the fabric, superior release in the dryer, and reduced residual pouch staining.

  • Patent number: 4994193
    Abstract: Liquid fabric softening compositions for use in a rinse bath after washing with a detergent. The softening compositions contain certain specific water-soluble, light-stable dyes as colorants at levels which provide consumer acceptable colors. The colorants are added to the finished composition so that the dyes are predominantly outside of the dispersed softener phase, where they remain. The compositions are very desirable in that they are very unlikely to stain fabrics.

  • Patent number: 4988345
    Abstract: Absorbent articles such as disposable diapers, incontinent pads, sanitary napkins and the like that have absorbent cores that are suitable for rapidly acquiring and containing liquid in an especially effective and efficient manner. The absorbent core comprises a storage layer comprising hydrophilic fibrous material and discrete particles of absorbent gelling material and having an acquisition aperture so it can quickly acquire this discharged liquid; and a liquid handling layer comprising a resilient material that is mositure insensitive so to rapidly acquire liquids into itself through the acquisition aperture and distribute the liquid throughout the liquid handling layer to the storage layer. The storage layer also allows the liquid handling layer to be "drained" of the liquid that is acquired so that the liquid handling layer may have sufficient capacity to acquire and distribute subsequent loading of liquids.

  • Patent number: 4986882
    Abstract: Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkali-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.

  • Patent number: 4985271
    Abstract: The invention is a method for treating coffee beans to make a better-tasting and improved aroma coffee. Green coffee beans are first partially roasted to a Hunter a-color between about 3 and about 9, under roasting conditions sufficient to increase the Hunter a-color of the beans by at least about 1.5 a-color units during the partial roasting step. The partially roasted beans are then treated with either an alkaline solution comprising water and a foodgrade base, or a coffee bean extract solution comprising water and from about 1% to about 12% coffee solids. Preferably, the partially roasted beans are treated by soaking them in the solution at a temperature between about 65.degree. F. (18.degree. C.) and about 120.degree. F. (49.degree. C.) for a time between about 2 hours and about 24 hours.

  • Patent number: 4983315
    Abstract: Disclosed are the N,N'-(1-oxo-1,2-ethanediyl)-bisaspartates comprising the moiety ##STR1## methods for their preparation (including an unexpected preparation from glyoxal bisulfite and aspartic acid in concentrated aqueous alkaline media) and useful compositions containing the same; illustrative are general-purpose sequestrant compositions, chelating agent compositions for transition metals such as iron, manganese and copper, general-purpose laundry detergent compositions and detergent compositions comprising perborate bleach, a bleach activator and, as a bleach stabilizer/performance enhancer, the novel bisaspartates. These unique nonphosphorus compounds are useful at low levels and differ from traditional --N--C--C--N-- chelating agents such as ethylenediaminetetraacetates by the presence of one amino- and one amido- functional group which it is believed will provide additional advantages, such as improved biodegradation.

  • Patent number: 4981220
    Abstract: A method of and apparatus for separating and removing seeds from a juice/juice sac slurry. In one embodiment of the present invention, a juice/juice sac slurry is deposited onto the upper surface of an inclined, vibrating bed. The bed includes a plurality of ridges and valleys that form channels, and a plurality of pins and dams projecting upwardly from the bed. The high frequency vibrations imparted to the bed cause the juice sacs to travel up the bed to a point where they are collected while the seeds bounce off and tumble down the bed to another point where they are collected and discarded. Also disclosed and described are apparatuses for and methods of extracting fruit meat sections from a whole fruit, and an apparatus for and method of separating sectional membranes from the fruit meat section to produce the juice/juice sac slurry.

  • Patent number: 4979782
    Abstract: Process and apparatus for the production of bristle products from plastic. The products comprise a bristle carrier and bristles whose utilization-side ends are substantially unformly rounded and located in a contour differing from that of the bristle side surface of the bristle carrier. The opposite ends of the bristles are fastened to the bristle side surface of the bristle carrier. In a particularly preferred embodiment, the process comprises the steps of: clamping the bristles while their utilization-side ends are in a flat plane; substantially uniformly rounding the utilization-side ends of the bristles while they are clamped in the flat plane; loosening the clamp restraining the bristles and thereafter axially displacing the utilization-side ends of the bristles relative to one another to produce the desired contour; and fastening the opposite ends of the bristles to the bristle carrier.

  • Patent number: 4977826
    Abstract: Method of an apparatus for extracting whole juice sacs from citrus fruits by fluid impinging chunks of peeled fruit meat. In one embodiment, a fruit chunk is fed into a fluid impingement chamber that includes a plurality of off-center orifices. High-pressure fluid emitted from the orifices strikes the fruit chunk and spins it such that the fruit chunk's juice sacs are stripped from the chunk's sectional membranes. In another preferred embodiment, a plurality of fluid impingement chambers are incorporated into a high-speed, continuous motion turret. In yet another preferred embodiment, fruit chunks are fed into an inclined tube that includes fluid orifices which emit high pressure fluid. Controlling the fluid pressure, nozzle orifice size, number of orifices, direction of fluid jets, impingement time, and size and shape of the fruit chunks determine how substantially the radial membranes of fruit chunks are stripped of juice sacs without shredding the membranes.
