Patent EP-0474892-A1 (EP)
Inventor: PAUL HERBERT DIPL-ING
IPC: C12C3/12
Filed: 1990-09-10
Abstract: Aluminium or an aluminium compound, preferably aluminium trioxide, is added to the carbon dioxide hop extract in a concentration such that the aluminium:alpha acid (alpha-humulone) molar ratio is 1:0.1 to 1:6. The mixture is subsequently treated with a high concentration of alkali metal hydroxide at a temperature of 80 to 160 DEG C. Isohumulone is obtained from the extract by adding sufficient water at a defined temperature for the isohumulone content to be 1 to 10% and the temperature to be reduced to 40 to 45 DEG C, and after further cooling to room temperature in a conventional way the alkali metal isohumulones being purified from the other constituents and, where appropriate, converted into isohumulones in a conventional manner.

Abstract: An apparatus for use in dimming fluorescent lamps (10) by alternating cathodes operates with pulsating unidirectional arc currents for a duration that is long relative to the filament thermal time constant, but short in relation to the mercury migration time constant of the fluorescent lamp. The invention provides full bridge switching and full bridge clamping topology in a trigger driver (270, 276) as well as a power driver (322) to prevent low voltage power supply "ride up". The cathode heater current is sensed to detect a failed cathode and to control the phase switching to a good cathode if a cathode failure occurs. A balanced-to-group ground lamp drive voltage improves ignition of the lamp plasma and lamp luminance uniformity when the lamp is operated dimly. A logarithmic amplifier (214) in a closed loop operation provides analog compression and also a logarithmic dimming response. Flash protection (230) eliminates pilot distractions.

Abstract: A transmitted light generated when a beam from a laser beam source (01) is applied to a specimen is combined with a laser beam from a local oscillation beam source (02) whose frequency is different from that of the applied laser beam through a half mirror (03), and the combined light is received by a light receiving element (04) that restricts each division area to not larger than a minimum space resolution unit where an interference between different points is generated when the propagation area of light is divided to generate a Fraunhofer diffraction image. The whole or part of the Fraunhofer diffraction image of the zero order, or a diffraction image up to n times the zero order spectrum are detected by a photodetector (05). Since the transmitted image can be separated from a scattering component and detected by extracting the beat component of the combined light, and information on an absorber can be obtained even when the scattering component is large such as with light passed through a specimen of an organism, etc., the application of this device to the optical CT, etc. becomes possible.

La lumière entrant par la face d'incidence (31) selon un angle d'incidence faible est réfléchie par réflexion interne totale à tour de rôle par la surface externe inférieure (32) d'une première cavité (33), par la partie centrale de la surface supérieure (34) d'une seconde cavité (35) et ensuite par la surface inférieure interne (36) de la première cavité (33) avant de sortir par la face d'émergence (37).
