    摘要: A source of pulses of coherent radiation at a wavelength of approximately 1 μm, comprises a pump source for producing pump light; a laser cavity comprising an Yb3+-doped gain medium arranged to receive the pump light, the laser cavity being modelocked to generate laser pulses at a defined repetition rate; a pulse detector arranged to generate a pulse selection signal indicative of the repetition rate; a pulse selector arranged to reduce the repetition rate of the laser pulses responsive to the pulse selection signal from the pulse detector by passing only selected ones of the laser pulses; and at least one optical amplifier for amplifying the laser pulses of reduced repetition rate. The at least one optical amplifier can be configured for chirped or parabolic pulse amplification.

    摘要: A blowbox for use in a plant for drying a material web includes an essentially horizontal box wall having formed therein circular orifices and eyelid perforations each of which includes a slit extending in parallel with the center line of the upper box wall. A depression is formed m the upper box wall adjacent one side of the slit. The eyelid perforations are arranged in two rows and parallel with the center line and together they form a zigzag pattern about the center line that intersects the depressions of the eyelid perforations in both rows. The orifices are disposed in a first and second pair of rows with both rows in each pair positioned on either side of and spaced equally from the center line. The upper box wall has a shallow continuous arcuate shape across its entire width.

    摘要: Method and apparatus for separating one or more agents, specially solvents, from gases. The agent or the agents are adsorbed by an adsorbent and thereafter desorbed and separated in a condenser (18). The regeneration of the adsorbent includes two steps. In the first step the agent or the agents are separated from a part of the adsorbent by heating. In this way the concentration of the agent or the agents is increased in those parts of the adsorbent which are closest to the condenser. In a second step the remaining parts of the adsorbent are regenerated.
