20130164211 | Process for Producing Ammonium Salts - In one embodiment, the invention is to a process for purifying a by-product stream. The process comprises the step of providing a by-product stream comprising an ammonium salt, dimerized amide, and optionally water. The process further comprises the step of precipitating at least a portion of the dimerized amide in the by-product stream to form solid dimerized amide. The process further comprises the step of separating the solid dimerized amide from the by-product stream to form a treated by-product stream comprising less than 1 wt. % solid dimerized amide. | 06-27-2013 |
20130331565 | Process for Producing Acesulfame Potassium - In one embodiment, the invention relates to processes for producing acesulfame potassium. In one embodiment, the process comprises the step of reacting a first reaction mixture to form an amidosulfamic acid salt such as a trialkyl ammonium amidosulfamic acid salt. The first reaction mixture comprises sulfamic acid, an amine, and smaller amounts, if any, acetic acid, e.g., less than 1 wt % (10000 wppm). In terms of ranges, the first reaction mixture may comprise from 1 wppm to 1 wt % acetic acid. The process further comprises the step of reacting the amidosulfamic acid salt with diketene to form an acetoacetamide salt. In preferred embodiments, the amidosulfamic acid salt formation reaction is conducted at pH levels from 5.5 to 7.0. The process further comprises the step of deriving the acesulfame-K from the acetoacetamide salt. | 12-12-2013 |

20130234683 | BOOST CONVERTER AND METHOD FOR ITS OPERATION - In a boost converter operation, a first voltage that is independent of an input voltage of the boost converter is preset in the boost converter, having an increased voltage level compared to the input voltage, as the setpoint output voltage, as long as the input voltage is below a first voltage threshold value, which is lower than the first voltage. As soon as the input voltage exceeds the first voltage threshold value, a second voltage that is a function of the input voltage is preset, having a lower voltage level compared to the input voltage, as the setpoint output voltage. As soon as the input voltage drops below a second voltage threshold value, which is lower than the first voltage, the first voltage is again preset as the setpoint output voltage. | 09-12-2013 |
