  • DEVICE AND METHOD FOR STORING HEAT
    Publication number: 20110271953
    Abstract: The invention relates to a device for storing heat, comprising a heat storage medium which absorbs heat in order to store heat and releases heat in order to use the stored heat, and a container for holding the heat storage medium, the container being closed by a gastight cover, and the device comprising volume compensation means in order to compensate for a volume increase of the heat storage medium (3) due to a temperature rise and a volume decrease due to a temperature reduction.

  • Fiber-optical sensor
    Patent number: 5011279
    Abstract: In a fiber-optical sensor used for measuring the Doppler broadening of scattered laser light by the principle of quasi-elastic light scattering (QELS), the scattered light originating from particles in movement, the emergence surface (7) for the laser light at the end of a single-mode or multimode light guide (3) used as an immersion probe is inclined at an angle 0<.phi..ltoreq.15.degree., preferably 1.degree..ltoreq..phi..ltoreq.6.degree., the angle of inclination being de-fined by the optical axis (8) of the light guide (3) and the normal (9) of the emergence surface (7).
