20100305322 | Process for the Oxidation of Secondary Amines into the Corresponding Nitroxides - The invention relates to a process for the preparation of secondary nitroxide radicals from their corresponding secondary amines by oxidation with an organic peracid, comprising the steps a) adding to a reaction vessel a secondary amine, optionally together with an organic solvent and in one batch a base selected from the group consisting of alkali metal, alkaline earth metal or ammonium bicarbonates and alkaline earth metal or ammonium carbonates or mixtures thereof in the form of a solid together with water or as an aqueous slurry; b) dosing a peracid under stirring to the reaction mixture in an amount of 1.0 to 2.5 mol per mol of secondary amine; and c) isolating the organic phase. | 12-02-2010 |
20110212864 | BENZOTRIAZOLE COMPOSITIONS - The invention relates to novel (benzo)triazole compositions comprising mixtures of benzotriazoles and N-substituted benzotriazoles in functional liquids, e.g. mineral oil. The mixtures can be prepared from readily obtainable starting materials, such as tolutriazole (TTA), alkyl aldehydes and cycloalkanols. The invention furthermore relates to a process for protecting metals, which are in contact with functional liquids comprising the mixtures. | 09-01-2011 |

20100121277 | MEDICAL INFUSION SYSTEM WITH PULSE WIDTH MODULATION AND SAFETY CIRCUIT - A medical infusion system with pulse width modulation and a safety circuit and a method thereof are disclosed. Embodiments of the system include a switching device and a pump motor, wherein the pump motor and the switching device are connected in series and constitute a power supply circuit to be connected to a power supply. Embodiments of the system further includes a control signal generator configured to generate a control signal e.g. PWM, and which is connected to input of the safety circuit. Output of the safety circuit is connected to a control input of the switching device such that the pump motor will not operate if there is no control signal applied to the input of the safety circuit. | 05-13-2010 |
