20100093880 | RECYCLING CLEAVAGE OF POLYURETHANES - A process is described for splitting polyurethanes and polyurethaneureas, in which the polymer is first reacted with gaseous or liquid secondary aliphatic or cycloaliphatic amines, the secondary urea formed, after removal with hydrogen chloride, is split to the isocyanate, and the polyols or polyamines also formed in the reaction are worked up and purified. It is possible by the process according to the invention to work up polyurethanes, polyurethaneureas, etc., of any origin, and to break them down into the starting materials, specifically the isocyanates, polyols or polyamines, to form starting materials in very high quality, which can be reused for the synthesis of any polyurethanes or polyureas. The invention further provides for the preparation of secondary bis-ureas from polyurethanes or polyurethaneureas or/and ureas. | 04-15-2010 |

20130069646 | METHOD FOR THE COMPARATIVE ANALYSIS OF PROTEIN PREPARATIONS BY MEANS OF NUCLEAR MAGNETIC RESONANCE - The invention relates to a method for the comparative analysis and control of the quality of a protein preparation by means of nuclear magnetic resonance (NMR) spectrometry. This method can be used to compare three-dimensional protein conformations in different protein preparations without requiring the samples to undergo any particular preparation. In particular, the method can be used to determine if a selected protein is in the same three-dimensional conformation in different protein preparations, if it is degraded in the formulation or if it is interacting with some of the excipients present. Specifically, the method can be used for the analysis and control of the quality of therapeutic compounds, particularly biodrugs or biosimilars, in different samples, without altering said samples. | 03-21-2013 |

20120316033 | METHOD FOR CONTROLLING AN AUTOMATED FRICTION CLUTCH - The invention relates to a method for controlling an automated friction clutch arranged in a drive train of a motor vehicle between an internal combustion engine and a transmission, and is operated in a travel-controlled manner by means of an actuator controlled by a control unit and transmits a maximum clutch torque while the friction clutch is closed, where an engine's torque provided by the internal combustion engine is reduced when the maximum clutch torque is exceeded and is increased when the maximum clutch torque rises. The engine torque is reduced which corresponds to a reduced transmittable clutch torque when the reduced transmittable clutch torque is detected and is increased to the engine torque corresponding to the maximum transmittable clutch torque after a first time interval expires, where the engine torque is limited by means of a second, longer time interval when a reduced transmittable clutch torque is detected. | 12-13-2012 |

20120243564 | SYSTEM AND METHOD FOR AGILE REMOTE GENERATION OF A BROADBAND TUNABLE SHORT-PULSE EMISSION - A method comprising using a pulse shaper in the spectral domain to generate multiple-color pulses directly at the output of the laser amplifier. The delay can thus be controlled directly in the spectral domain and there is no need for an optical delay line. The method allows reducing the number of optical components and insures insensitivity to alignment, vibrations and turbulence on long distance propagation and filamentation, particularly in air. The method allows programmable and tunable interaction, since the pulse shaper is able to control the laser spectral amplitude and phase. | 09-27-2012 |
