  • Patent number: 7566165
    Abstract: A manifold comprises a conduit for conveying a fluid stream, a plurality of nozzles, and a plurality of valves. Each nozzle is connected to a corresponding port in the conduit, and each valve is connected to a corresponding nozzle. The ports can be disposed at discrete locations on two or more transverse planes of the conduit and such that no longitudinal, diametrical plane of the conduit passing through the center point of any one of the ports is coplanar with a longitudinal, diametrical plane of the conduit passing through the center point of a longitudinally adjacent port. Alternatively, the ports can be disposed at discrete locations on the conduit such that no longitudinal, diametrical plane of the conduit passing through the center point of any one of the ports is coplanar with a longitudinal, diametrical plane of the conduit passing through the center point of any other port.

  • Patent number: 6127470
    Abstract: This invention relates to a fluid dispersion of at least one dibenzylidene sorbitol acetal derivative. The sorbitol acetal derivative is useful as a clarifying agent for polyolefins and the inventive fluid dispersion permits improvements in the handling and processing of and mixing within the polyolefin composition. The inventive dispersion must be shelf stable, retain its nucleating effects, be compatible with polypropylene (and other polyolefins), and possess both short-term and long-term viscosities which permit acceptable transport through a standard polyolefin-manufacturing peristaltic pump. The preferred inventive dispersion thus comprises 3,4-DMDBS and at least one ethoxylated nonionic surfactant having an HLB of greater than about 8.5. Preferred surfactants include those selected from the group consisting essentially of ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters and ethoxylated nonyl-phenol ethers.

  • Patent number: 4908149
    Abstract: A liquid or dry, flowable cleaning composition for carpeting is provided which comprises: (1) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid, or mixtures of water, surfactant and organic liquid; and (2) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets. In the case of a dry-type composition sufficient particulate material is added to provide a dry, flowable product.

  • Patent number: 4374068
    Abstract: A process is provided for hydroxyalkylation of cyanoethylanilines, which comprises reacting an alkylene oxide of the formula: ##STR1## wherein R.sub.1 is selected from H, Cl, Br, OH, a lower alkyl group containing from 1 to about 4 carbon atoms, or phenyl with a cyanoethyl aniline in a molar ratio of from about 1:1 to about 2:1 in a reaction medium at a temperature of from about 40.degree. C. to about 130.degree. C. in the presence of an acid catalyst provided in an amount sufficient to catalyze said reaction to thereby provide the corresponding hydroxyalkylated cyanoethyl aniline.
