  • Patent number: 9216804
    Abstract: Pod drive which can be fitted to a vessel and which is provided with an electric motor which drives a propeller shaft which is likewise provided in the housing of the pod drive and is connected to a propeller which is situated outside the latter. It is proposed to use a fast-rotating electric motor in combination with a reduction gearing for driving the propeller shaft. The mounting of the propeller shaft is made particularly stable by mounting it on both sides of the electric motor. The reduction gearing may include a planetary system. The electric motor may be fitted next to the hollow propeller shaft. In this case, several electric motors can be arranged around the central propeller shaft. It is also possible to make the rotor of the electric motor hollow and to fit the propeller shaft inside the latter.

  • Publication number: 20140150438
    Abstract: A system for operating a thermal power plant during off-peak demand intervals includes a gas turbine having a compressor, a combustor connected to a fuel control system, a turbine and a sensor configured to sense ambient conditions around the gas turbine. The fuel control system and the sensor are in communication with a controller. The controller is configured to receive a user input that corresponds to a value for an operational boundary condition of the thermal power plant and to monitor ambient conditions through the sensor. The controller is further configured to generate a predicted emissions level value for the gas turbine based on the monitored ambient conditions and to generate a command signal to adjust at least one operational parameter of the gas turbine based at least in part on the predicted emissions level value and the value of the operational boundary condition of the thermal power plant.

  • Patent number: 7841015
    Abstract: A method is described for determining a dopant concentration on a surface and/or in layer region lying close to the surface of a semiconductor sample using an atomic force microscope, whose leaf-spring tip is brought into contact with the semiconductor sample, forming a Schottky barrier, wherein an electric alternating potential is applied between the spring-leaf tip and the semiconductor sample in the region of the Schottky barrier in such a way that a space charge region inside the semiconductor sample defining the three-dimensional extension of the Schottky barrier is excited and begins to oscillate within the confines of its spatial extension, said oscillations are transmitted to the leaf-spring, are detected and form the basis for determining the dopant concentration.

  • Patent number: 7657947
    Abstract: A method for exciting free torsional vibrations a spring cantilever, which is clamped in on one side and has a longitudinal extension, of an atomic force microscope (AFM) is disclosed. The invention provides by the one-sidedly clamped-in spring cantilever being placed at a distance over a surface between which and the spring cantilever there is an acoustic coupling medium, by the surface being set into oscillations which are oriented laterally to the surface and are polarized linearly along an oscillation direction, and by the polarization axis given by the oscillation direction being oriented perpendicular to the longitudinal extension of the spring cantilever.

  • Patent number: 7360404
    Abstract: A method for examining a surface of a sample is described using an atomic force scanning microscope (AFM) comprising a cantilever with a longitudinal extension along which a measuring tip is disposed, which is selectively arranged relative to the sample surface by a means for driving and whose spatial position is detected using a sensor unit. Vibration excitation is conducted at excitation amplitudes which produce inside the cantilever torsional amplitudes with maximum values which form a largely (substantively) constant plateau value despite increasing excitation amplitudes and the resonance spectra, in a range of maximum values of the torsional amplitudes, a widening of the resonance spectrum which is determinable by a plateau width. The resonance spectra, preferably the plateau value, the plateau width and/or the gradient of the respective resonance spectra are used for examining the sample.

  • Patent number: 6389885
    Abstract: An ultrasonic microscope for acquiring data from internal regions of a sample body is provided. The ultrasonic microscope includes an ultrasonic transmitter for providing a point source of ultrasonic waves for input-coupling into a sample body at a point in proportion to the dimensions of the sample body. Ultrasonically-induced excursions of a receiving tip can be detected with atomic resolution by using an ultrasonic detector that measures with high sensitivity resolution. The ultrasonic transmitter and the ultrasonic detector may be positioned relative to one another such that the ultrasonic detector can adopt several receiving positions for each transmitting position of the ultrasonic transmitter. A measurement data signal from the ultrasonic detector is stored and processed in a central processor. An image generator within the central processor uses a tomographic algorithm to reconstruct an image of at least one area inside the sample body from the measurement data.

  • Patent number: 5879903
    Abstract: Selection of Streptomyces viridochromogenes DSM 4112 for resistance to phosphinothricyl-alanyl-alanine (PTT) results in PTT-resistance selectants. The DNA fragment which carries the phosphinothricin(PTC)-resistance gene is obtained from the total DNA of these selectants by cutting with BamHI, cloning of a fragment 4.0 kb in size, and selection for PTT resistance. This gene is suitable for the production of PTC-resistant plants, and as a resistance marker and for the selective N-acetylation of the L-form of racemic PTC.

  • Patent number: 5852233
    Abstract: An acoustic microscope allowing both the topography and the elasticity of a sample to be measured at the same time. To this end the displacement of a cantilever with a tip is measured by the deflection of a laser beam. In order to measure the topography, the average deviation of the tip is held constant by a regulation circuit. The regulation circuit consists of a split-photodiode which supplies a neutral signal to the output of a normalizing amplifier which delivers a neutral value. Deviations from this neutral signal are compensated by a z-electrode of a piezocrystal. The elastic properties of the sample are measured by coupling ultrasound into the sample by means of a transducer and the high-frequency displacements of the cantilever with the tip are detected by a second detection device that consists of knife-edge detector and a fast photodiode. The detection device may also consist of a heterodyne time-of-flight interferometer or a capacitive detection scheme.
