    摘要： Device for removal of sediment particles from the water in a cultivating tank (1), where a cylindrical outlet (3), connected to an outlet tube (22) is located on the vertical axis of symmetry of the tank (1). Means (19), e.g. a plate (19), forming a slot (15) is located against the upper edge of an annular chamber (8). The annular chamber (8) is located around the outlet (3), and has an outlet tube (12) for particle-enriched water. For use in a cultivating tank having a flat bottom, the chamber (7) may have a slant section (24) from the bottom (6) of the tank, diverging inwardly against the annular chamber (8). The device may also be used for separate monitoring of a zonal divided tank (1). The concentrated particle flow in the outlet tube (12) is individually monitored in a monitoring unit (28), connected to means for controlling feeding, water provision and oxygen provision.

Date Feb. 3, 1994A method for active noise reduction based on destructive interference of sound waves in order to reduce the energy in a sound field employs two omnidirectional microphones (M1, M2) provided in connection with a loudspeaker. The acoustic feedback of the microphones is eliminated by a closed loop consisting of the microphones and the loudspeaker. The loudspeaker used is an open loudspeaker with a dipole characteristic, thus causing one of the microphones to be more sensitive to the far field and thereby to the noise which has to be suppressed. The method is implemented by a device which comprises a digital signal processor (DSP) for processing the microphone signals and which transmits an output signal to the loudspeaker where the feedback component from the loudspeaker is substantially eliminated, while the output signal's phase and amplitude are adjusted in such a manner that an effective cancellation of the noise is obtained in an area around the loudspeaker's near field. The DSP can preferably be implemented in the form of software modules on an integrated circuit. With the method and the device an integrated reduction in noise level of almost 20 dB is achieved depending on how the filtering in the DSP is adapted. In practice a quiet zone can be obtained in the loudspeaker's near field with an attenuation band which extends from approximately 100-500 Hz.

    摘要： It is described a method for automatic state control, inspection, cleaning and/or surface treatment of structures, especially measuring the thickness of plate constructions and pipes by means of ultrasound signals from a self-propelled, remotely controllable unit (1). The self-propelled unit (1) is continuously moved in the measurement area, and a transmitter (6) transmits an ultrasound signal in a direction substantially perpendicular to the surface of the construction. A reflected signal is received by a receiver (6), determining thickness and material quality of the construction at the measurement spot, on the basis of received reflected signal, and parameters such as transit time for the reflected signal. The self-propelled unit (1) performs self-positioning by means of previously known spots on the construction. All received data regarding waveform of the reflected signal is stored in a computer, and thickness and material quality are verified by comparing data for received signal in one spot, with data for received signals in adjacent spots. The steps are repeated for collection of data for new measurement spots.

    摘要： PCT No. PCT/NO90/00075 Sec. 371 Date Dec. 23, 1992 Sec. 102(e) Date Dec. 23, 1992 PCT Filed Apr. 27, 1990 PCT Pub. No. WO91/16981 PCT Pub. Date Nov. 14, 1991.A method and apparatus for removing sedimented particles from a fluid stream in a settlement basin. In the bottom of the basis there is a sluice which may include a sluice gate. The basin includes a longitudinal, flexible pipe unit which is shaped such that it can seal the edges of the sluice. The pipe unit can move up and down within the basin by filling the pipe with a fluid, i.e. water or air. Depending on the initial position of the pipe, upward or downward movement causes the pipe to seal against the edges of the sluice. By adjusting the amount of water and air in the pipe, it is possible to adjust the extent to which the sluice is sealed.
