  • Patent number: 6800771
    Abstract: The invention relates to stabilized amido acid compositions. More particularly, the invention relates to compositions of amido acids, such as 6-nonanoylamidohexanoic acid, stabilized with antioxidants. The stabilized amido acid compositions are useful in the manufacture of bleach activators such as sodium nonanamidohexanoyloxybenzenesulfonate. Bleach activators made from the stabilized amido acids of the invention are capable of possessing improved coloration.

  • Publication number: 20040112333
    Abstract: A stabilizer system creates a temporary droop to stabilize a governor for an internal combustion engine and reduce permanent droop and hunting of the engine. The governor adjusts the position of a throttle in response to engine speed to achieve a desired engine speed. The stabilizer system temporarily applies a force on the governor that initially resists sudden movement of the governor arm, and causes a temporary speed droop. The initial resistance of the stabilizer system helps prevent the governor from overshooting the desired speed and hunting. The temporary droop is then removed to permit the governor to achieve the desired speed to help prevent permanent droop.

  • Publication number: 20030158079
    Abstract: The present invention relates to a benefit agent delivery system that can, when directly applied to a substrate, provide a longer benefit term than when a benefit agent alone is applied to said substrate. Typical benefit agents include perfume raw materials such as perfume aldehydes and ketones.

  • Patent number: 6595897
    Abstract: A combination speed limiter and transmission interlock system for an engine-transmission power train that includes an internal combustion engine and a transmission, the power train of the type used to power outboard engines and the like. The system utilizes fewer connections, is less expensive, is expected to be more reliable, utilizes a single housing, is easier to manufacture, and uses fewer components than a power train that utilizes separate speed limiter and transmission interlock modules.

  • Publication number: 20030134772
    Abstract: Disclosed herein are benefit agent delivery systems which are formed by separately adding to a liquid or granular matrix certain kinds of primary amine compounds and selected types of benefit agents, e.g., perfumes, in the form of aldehydes or ketones. When substrate surfaces are treated with aqueous solutions or dispersions of such delivery systems, the benefit agent is indirectly exposed to and preferably deposited on the substrate surface in such a manner that it provides its benefit to the surface for a longer period of time than when the amine compound is not present. Such benefit agent delivery systems are especially suitable for incorporation into laundry detergent or other fabric-treating products.

  • Patent number: 6527690
    Abstract: The invention relates to a process for purifying and decolorizing a phenyl ester salt. The process combines a phenyl ester salt with a solvent to form a mixture and then stirs the mixture to form a slurry. The phenyl ester salt is substantially insoluble in this solvent. The process then collects the phenyl ester salt from the slurry. The collected phenyl ester salt may then be optionally dried or recrystallized. The collected phenyl ester salt is dissolved in a solvent to form a solution. The solution is decolorized and then spray dried to form a powder of the phenyl ester salt. As a result of the process the phenyl ester salt powder has a higher purity and an improved color as compared to the starting phenyl ester salt.
