  • Publication number: 20090099057
    Abstract: Improved highly aqueous, alkaline hard surface cleaning compositions useful in the cleaning of hard surfaces, particularly hard surfaces bearing greasy stains or soils. Preferred compositions comprise amine oxide as the sole surfactant constituent, an alkalinity constituent, preferably an alkanolamine and as the sole organic solvent constituent, an alkylene glycol phenyl ether, and water, optionally further including a dye and/or fragrance composition. The compositions provide excellent cleaning of greasy soils on hard surfaces.

  • Patent number: 7203049
    Abstract: The over-current protection device of the present invention uses the unbalanced properties of the thermal expansion coefficients between the outer and inner sides for an upper metallic conductive sheet and a lower metallic conductive sheet to generate a torque to deform outwardly. The torque is used to pull a current-sensing element and present with at least a cracking face, so as to introduce an electrically open effect similar to a fuse. Thus, the present invention can achieve the object for preventing the danger of circuit system by the short circuit during the burning of over-current protection device.
