20100326051 | Operating and Diagnostic Method for an SCR Exhaust-Gas Aftertreatment System - The invention relates to In an operating and diagnostic method for an SCR exhaust gas aftertreatment system which has an SCR catalytic converter with ammonia storage capacity, a signal of an exhaust gas sensor that is sensitive to nitrogen oxide and ammonia and is arranged downstream of the SCR catalytic converter, is measured. In a normal operating mode, ammonia is supplied to the SCR catalytic converter corresponding to a filling level model for ammonia stored in the SCR catalytic converter, in such a way that the ammonia filling level of the SCR catalytic converter is held at least approximately at a predefinable nominal value (or value range). The normal operating mode is interrupted if an exhaust gas sensor signal that exceeds a predefinable first limit value, is registered, and the set urea dosing rate is increased by a predefinable degree in relation to the value provided in the normal operating mode. Thereafter, a return is made to the normal operating mode, or a switch is made to a diagnostic operating mode, as a function of the profile of the signal of the exhaust gas sensor. | 12-30-2010 |

20110139728 | Device and Process for Substance Separation in a Microstructured Apparatus - The invention relates to a device for separation of substance mixtures on the micro scale. The invention further relates to a process for separating substance mixtures using the inventive device. The device is a device for separating substance mixtures and for performing chemical reactions between immiscible fluid media on the micro scale, comprising a first channel plate with at least one first process channel for a first fluid medium, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the first process channel, and a further connecting or distributing channel which connects the first process channel to the outlet, a second channel plate with at least one second process channel for a second fluid medium immiscible with the first, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the second process channel, and a further connecting or distributing channel which connects the second process channel to the outlet, and a microscreen as a separating means between the two process channel, wherein the microscreen has a multitude of orifices which have an aspect ratio of 1.5 to 10. | 06-16-2011 |

20100201215 | ROTATIONAL DISPLAYS - A rotation apparatus includes at least one magnet, and a flexible suspension coupled to the at least one magnet. The at least one magnet is suspended from the suspension, Moreover, when the flexible suspension causes rotation in a first direction via a force, the at least one magnet alternately rotates in the first direction and in a second direction opposite the first direction. | 08-12-2010 |
