Inventor: WAN CHUNG-ZONG
IPC: B01J37/02
Filed: 1987-06-25
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE A method of making a catalyst composition comprising an activated alumina coating stabilized against thermal de-gradation includes applying a coating of alumina having one or more platinum group metal catalytic components dispersed thereon onto a carrier substrate and calcining the coating.          The calcined coating is then impregnated with a solution of a thermal stabilizer-precursor and calcined again to provide a thermal stabilizer in the alumina.  Bulk ceria, optionally an aluminum-stabilized bulk ceria, may also be added to the composition, preferably at specified minimum levels, includ-ing a high purity bulk ceria on which one or more non-rhod-ium platinum group metal catalytic components, e.g., platin-um, optionally, are dispersed.  A separate aspect of the in-vention provides for a method of making a catalyst composi-tion including dispersing one or more platinum group metal catalytic components on an activated alumina and calcining the combined alumina and platinum group metal catalytic components.  The steps are carried out under limited acidi-fication conditions whereby at least minimum dispersions of the platinum group metal catalytic components are attained.          The invention also provides for catalyst compositions re-sulting from either or both the foregoing methods.

Abstract: METHOD AND APPARATUS FOR AUTOMATED ASSESSMENT OF THE IMMUNOREGULATORY STATUS OF THE MONONUCLEAR LEUKOCYTE                     IMMUNE SYSTEM         ABSTRACT OF THE INVENTION         The ability of mononuclear leukocytes to respond to standard stimuli is measured based on the expression of activation antigens on mononuclear cell subclasses.  In a preferred embodiment, a sample of mononuclear leukocytes is cultured for up to 24 hours with a standard stimulus known to activate such cells.  After culturing, aliquots of the cells are incubated with fluorophore-conjugated monoclonal antibodies to antigenic determinants of a particular mononuclear subclass and different fluorophore-conjugated monoclonal antibodies to particular activation antigens. The incubated aliquots are analyzed on a flow cytofluorometer, whereby each cell is illuminated with a particular light (e.g. argon ion laser), which detects and measures forward light scatter, orthogonal light scatter and two different wavelengths of light emitted from the fluorophores.   These parameters are used to identify and enumerate the cells of different subclasses present within the mononuclear leukocyte sample, the cells of said subclasses which have been induced to express a particular activation antigen and the quantity of the activation antigen on said cells.  An analysis of these enumerations is shown to correlate with the immunoregulatory status of the mononuclear leukocyte immune system.  Data generation and analysis can be performed using a flow cytofluorometric apparatus with data and control signal processing to ensure accuracy and reproducibility of the results of the assay.

Title: Method and device for measuring the torque transmitted by the driving wheel of a cycle and a cycle equipped with said device
Inventor: MERCAT JEAN-PIERRE
IPC: A61B5/22
Filed: 1987-11-18
Granted: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE          The driving wheel of a bicycle or moped is fitted with radial spokes for ready detection of angular divergence between hub and rim under the action of torque.  The angular position of the hub is detected by means of a perforated disk having openings which pass in front of a photoelectric sensor.  A hoop attached to the rim is provided with rectangular notches which also pass in front of a photoelectric sensor.  The signals produced by the sensors are sent to an electronic unit for computing the torque from the time interval by which the hoop lags with respect to the disk.  In addition, detection of the passage of disk openings serves to calculate the speed which is displayed together with the power obtained by electronic multiplication of the torque by the speed.
