  • Publication number: 20180368384
    Abstract: An extendable and adjustable insect entrapment apparatus reaches insects and pests in hard to reach areas through a multi-jointed elongated rod that hinges and pivots into various configuration to reach and entrap the insects with a pad of stacked, singular sticky sheets. The rod has a proximal end with a formed hole for hanging the apparatus from a distal end. At least one joint in the rod is fixedly set at a desired angle and orientation. The sticky sheets retain any insects which travel or fall into a base at the distal end of the rod. Each sheet is coated with a mild compression adhesive material that entraps an insect in response to an application of force against the insect. Each sticky sheet can be separated individually. Upon entrapment of an insect, the outermost sticky sheet restraining the insect is separated, folded to encase the insect, and disposed of.

  • Patent number: 8875363
    Abstract: Disclosed are methods of making a dielectric on a metal foil, and a method of making a large area capacitor that includes a dielectric on a metal foil. A first dielectric layer is formed over the metal foil by physical vapor deposition, and a dielectric precursor layer is formed over the first dielectric layer by chemical solution deposition. The metal foil, first dielectric layer and dielectric precursor layer are prefired at a prefiring temperature in the range of 350 to 650° C. The prefired dielectric precursor layer, the first dielectric layer and the base metal foil are subsequently fired at a firing temperature in the range of 700 to 1200° C.

  • Patent number: 7259131
    Abstract: Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of sulfosuccinic acid or a salt of sulfosuccinic acid present in an amount of at least about 4% based on the weight of the sulfosuccinate surfactant.

    Abstract: Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties such as lather and are economical. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of electrolytes. The electrolytes are present at a level sufficient to provide at least about 0.1 equivalents of cationic ions per Kg of composition and maintains a viscosity of the composition at its initial value after storage for 4 weeks at 49° C.
