  • Patent number: 5200115
    Abstract: The aqueous paste contains an alkyl glucoside as non-ionic surfactant and an .alpha.-sulfofatty acid disalt as anionic surfactant; a thickener, for example carboxymethy cellulose, may also be present for adjusting viscosity. The paste-form detergent is produced by mixing concentrated aqueous pastes of the surfactants and, optionally, the thickener, the pH optionally being adjusted to a substantially neutral value by addition of a regulator. The paste-form detergents are suitable both for the washing of laundry and for the washing of hard surfaces, for example dishes.

  • Patent number: 5198140
    Abstract: This invention relates to a dual composition bar and extrusion nozzle therefore. The bar is formed of two different materials, preferably of separate colors, and has substantially sinusoidal upper and lower surfaces with a tongue and groove interlock therebetween. The extrusion nozzle utilizes two dies, the first of which has two die portions separated by a die element for forming a tongue and groove interlock between the two materials. The die element does not extend to the second die wherein the convoluted die portions squeeze the two materials together enhancing the interlock.

  • Patent number: 5196132
    Abstract: The present invention is directed to a novel single, unit-dose drycleaning article in which at least a portion thereof dissolves in a drycleaning solvent during the drycleaning cycle for releasing a premeasured amount of a drycleaning additive contained within the article. The single, unit-dose drycleaning article is generally in the form of a sealed tub formed of a polystyrene. The unit-dose tub preferably dissolves within about one minute after being in contact with the drycleaning solvent to ensure release and adequate mixing of the drycleaning additive with the drycleaning solvent to effect maximum drycleaning results. In an alternative form, the single, unit-dose drycleaning article may be partially formed with a material that dissolves in a drycleaning solvent.

  • Patent number: 5190697
    Abstract: A process for producing PTC (positive temperature coefficient) self-resetting overcurrent protection elements using two different crystalline polymers with an organic peroxide and carbon black. The mixture is kneaded at an elevated temperature. The two crystalline polymers include different proportions of tertiary hydrogen atoms to carbon atoms, so that the desired PTC characteristics of a highly crystallized polymer can obtain the benefit of greater proportions of tertiary hydrogen in a less highly crystallized polymer. A high degree of grafting to carbon black that increases the number of polymer having unpaired electrons in the crystalline polymer mixture through the decomposition of organic peroxide. The resulting mixture tends to disperse the carbon black uniformly throughout the resulting mixture, and to position the carbon black in a three-dimensional matrix in which it is fixed by cross-linking.

  • Patent number: 5186860
    Abstract: The compound ortho-methoxyaniline (o-anisidine) can be polymerized by both chemical and electrochemical means to produce polyanisidine, a soluble polymer of high electrical conductivity. Also called poly-o-methoxyaniline or PANIS, polyanisidine can be further blended with various other polymers enabling construction of devices with desirable electrical, optical and physical properties. Oxidative polymerization yields have been increased to 47 percent with no apparent loss in electrical conductivity. PANIS has been blended with polystyrene, polyacrylonitrile, polyethylene oxide and poly(trimethyl hexamethylene terephthalamide) (nylon) to form free-standing, stable, flexible films and fibers having electrical resistance values dependent upon the concentration of PANIS.
