    Abstract: L'agencement décrit permet d'assurer la stabilité de la valeur de consigne d'un analyseur de gaz. Le circuit de commande (30b) de la valeur de consigne utilise un amplificateur (192) qui est commuté alternativement entre une tension de référence et un signal de détection pour envoyer un signal à un processeur (39) représentant le signal de référence et le signal de détection. Le processeur (39) compare les deux signaux et règle le dispositif de chauffage (60) associé au détecteur pour établir une valeur de consigne stable de l'analyseur de gaz. L'agencement élimine le besoin d'utiliser des résistances de précision dans le circuit de commande de la valeur de consigne et, par conséquent, réduit considérablement le coût du circuit.

    Abstract: A measuring apparatus of the present invention measures the constituent concentration of a specimen after loading into the apparatus a test piece having a test material which develops coloring as a result of a reaction with the constituents of a specimen. When the apparatus detects that the test piece having the test material has been loaded, it automatically begins to measure the constituent concentration of the specimen. That is. after the loading of the test piece is detected, a predetermined time period is measured. During this time measurement, the time period is displayed at a predetermined time interval. After the time measurement of this predetermined time period is terminated, the test material is irradiated with a light, and the intensity of the light from the test material is detected. The constituent concentration of the specimen applied to the test material can be determined on the basis of the reflected light intensity thus detected. Furthermore, this measuring apparatus can detect a reverse insertion of a test piece, and is constructed so as to disable the measurement of the constituent concentration of a specimen if supplementary information to be stored along with measurement information has not been set.

    Abstract: An automatic refractometer comprising a photosensitive device having a relatively narrow dynamic range in the form of a linear scanned array including a plurality of photoelectric elements each providing an output pulse during a scan and the amplitude of each pulse being determined by the amount of illumination of the corresponding element by incident light, an optical system for directing light onto the array in a manner such that the particular photoelectric elements of the array which are illuminated by the light are determined by the index of refraction of a light transmitting substance placed in operative association with the optical system, a circuit for converting signals from the array into digital signals containing information as to the amplitudes of the signals from the array, a digital processing circuit for storing respective signals from reference and sample substances placed in operative association with the optical system and for computing the index of refraction of the sample substance by means of a comparison of the stored reference and sample information, and apparatus for providing a read out of the computed result. The digital processing circuit also calculates the percent solids in the sample substance, and the circuit also includes a plurality of channels for containing information to provide different interpretations of the index of refraction computed thereby. The circuit for converting array signals into digital signals comprises a peak detector circuit for detecting peak amplitudes of signals obtained from scanning the array and an analog-to-digital converter for providing digital signals containing information as to peak amplitudes of the array signals. There is also provided arrangements for measuring the temperatures of the sample substance and comparing to a reference for applying a temperature correction to the computed index of refraction, monitoring and regulating the temperature of the component of the optical system to which the sample substance is exposed, and monitoring and regulating the intensity of light incident on the array.

    Abstract: A reflectometer has an optical chamber comprising a light source (Q1) for illuminating a test specimen (9) and a relfec- tance photosensor (Q3) responsive to light reflected from the test specimen to produce a reflectance signal corresponding to the reflectance of the specimen. The reflectance photosensor (Q3) is disposed along an optical path (5) having its optical axis (12) inclined to the optical axis (11) of the optical path (4) along which light is projected onto the test specimen by the light source (Q1) so that the photosensor (Q3) detects random reflections from the test specimen (9). The optical chamber may also include a reference photosensor (Q2), a beam splitter (15) arranged to reflect a minor fraction of the light emitted by the light source (Q1) onto the reference photosensor, and a drive circuit for the light source which is responsive to a control signal derived from the reference sensor (Q2) and which provides for pulsed operation of the light source so as to maintain the control signal generally at a constant level.
