  • Patent number: 7435272
    Abstract: A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkoxylated amine or etheramine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkoxylated amine, such as isohexyloxypropylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy.

  • Patent number: 7182795
    Abstract: A middle distillate fuel additive comprising the reaction product resulting from the combining of a hydrocarbyl succinic anhydride and a hydroxyamine. The lubricating properties of low sulfur-content middle distillate fuels, such as diesel, jet or bio-diesel fuels, can be significantly improved by inclusion therein of such additive compounds. The use of these middle distillate fuel additives makes it possible to avoid mechanical failure problems, such as fuel pump or injector failure, otherwise caused by inadequate fuel lubricity, while still retaining the environmental benefits of using a low sulfur fuel.

  • Patent number: 7053066
    Abstract: The invention relates to a method for treating overweight persons or patients with obesity using a food composition able to control the release of glucose into the patient's blood. This is achieved by the introduction into the food composition of a therapeutically effective amount of an additive, such as propylene glycol alginate (PGA) or other hydrophilic agent or pharmaceutically acceptable salts thereof, which reduces the cooking losses and enhances the starch cell wall membrane to thereby slow the enzymatic hydrolysis of the starch by insulin. The result is a steady state release of glucose and a net reduction in the release of blood glucose (glycemic index) relative to release of glucose observed in an overweight or obese patient having consumed a food composition without propylene glycol alginate, whereby the patient experiences a loss in body weight.
