Abstract: An array of light-emitting diodes (1-15) in a circular arrangement are illuminated to indicate the discrete magnitude of rate-of-turn and the direction of turn. The number of diodes (1-15) illuminated is indicative of the discrete magnitude of turn and the clockwise or counterclockwise direction of illumination of the diodes is indicative of the turn direction. The current and preceding samples of the grey coded step data compass heading output are compared (12) to detect incremental changes in heading. The incremental changes are counted over a predetermined time interval to provide a count signal (14) representative of turn rate. Logic (14) responsive to the count signal illuminates the appropriate number of light-emitting diodes (1-15). Further logic (35, 36) responsive to the grey code head­ing data sequence provides a direction of turn signal to illuminate the light-emitting diodes (1-15) in a clock­wise or counterclockwise direction as appropriate.

Abstract: An improved process is disclosed for the conversion of natural gas into middle distillates. In the process, natural gas is converted into synthesis gas or syngas consisting essentially of carbonmonoxide and hydrogen. The syngas is contacted with a series of three catalyst beds comprising of an admixture of oxides of copper, zinc and aluminium in the first bed, an oxide of aluminium in the second bed and silicate salt of a rare earth metal in the third bed. From the aqueous phase, the olefinic hydrocarbons are separated and then converted into oligomers boiling in the middle distillates range by contacting with solid oligomerisation catalyst. The oligomers in admixture with hydro­gen are then converted into middle distillates by contacting the admixture with a hydrogenation catalyst. The middle distillates are well known for their varied applications as fuel and illu­minators.

Abstract: In a monitoring system, a tachometer (32) monitors the speed of a continuously moving web or article (12). A lens (20) focuses an image of a portion of the web in an examination region (14) on image section (22) of a CCD array. As the web moves, the image moves correspondingly along the image section. A synchronizing circuit (C) adjusts the frequency of a tachometer output signal and uses it in lieu of a fixed frequency oscillator as the master clocking or timing basis for generating clocking pulses for the CCD array. More specifically, the synchronizing circuit generates four phase clocking pulses which shifts lines of CCD data along the image section at the same speed that the image is moving along the CCD section. In this manner, the pixel values integrate light from the same area of the imaged web at each shifted position along the image section. Each line of data from the image section may be shifted at the same rate through an optically light-insensitive storage section and read out serially by shift rgisters to form a video signal. A quality control analysis circuit (D) monitors the video signal for selected characteristics of the imaged web. Preferably, a record is maintained of the location of flaws and defects noted by the quality analysis circuit.

Title: Titrage de la vitamine B12
Inventor: OH CHAN S
IPC: G01N33/82
Filed: 1989-05-19
Abstract: Un titrage compétitif de fixation pour la vitamine B12, dans un échantillon d'analyse, donne une courbe dose-réponse à forte pente dans les zones de concentration cliniquement significatives, fournissant une grande précision. L'analyse utilise la vitamine B12 immobilisée en vue de concurrencer la vitamine B12 dans l'échantillon d'analyse pour un partenaire de fixation. La quantité de partenaire de fixation liée à la vitamine B12 immobilisée peut être mesurée et est inversement proportionnelle à la concentration de vitamine B12 libre, dans l'échantillon d'analyse. Le partenaire de fixation est un facteur intrinsèque biotynilé de façon type, préparé de telle façon que la quasi-totalité des molécules du facteur intrinsèque soit biotinylée et que l'activité de liaison du facteur intrinsèque pour la vitamine B12 ne soit pas réduite. Le facteur intrinsèque biotynilé lié peut alors être déterminé en le faisant réagir avec l'avidine couplée à un groupe relationnel. Le groupe relationnel est généralement une enzyme, telle que la peroxydase du raifort, mais peut être un autre composé marqué détectable. La vitamine B12 immobilisée est liée, de façon générale, à un support solide, tel que des perles diazotées dérivées d'amines, la liaison pouvant se faire par l'intermédiaire d'un élément liant protéinique. D'autres partenaires de fixation tels qu'un anticorps antivitamine B12 sont également utilisables. Le partenaire de fixation peut être marqué directement avec le groupe relationnel. La méthode peut être adaptée au titrage du sérum; des méthodes d'inactivation de protéines endogènes fixant la vitamine B12 dans le sérum sont décrites.

Abstract: An apparatus for displacing material includes a transport thread composed of a central thread spiral and an outer thread. The outer thread spiral is fixed to one of the radially directed defining surfaces of the central thread spiral. The central thread spiral is dimensioned so as, without permanent deformation, to absorb at least the major portion of the mechanical forces occurring in the axial and radial direction of the transport thread. The outer thread spiral has an outer surface which faces away from the geometric centre axis of the transport thread and is of shorter extent in the axial direction of the transport thread and is located more distally from the center axis than the outer surface of the central thread spiral. By regulating the extent in the axial direction of the transport thread of the surface of the outer thread spiral turned to face the substrate, the abutment pressure of the transport thread will be adapted to the substrate in relation to the properties of the material being displaced.
