Abstract: L'invention concerne un dispositif et un procédé permettant de déterminer le taux de monoxyde d'azote dans l'air expiré. Un dispositif initial est conçu pour déterminer le taux courant de monoxyde d'azote pendant une phase d'expiration. Selon l'invention, l'air expiré passe, pendant la période de commencement de la phase d'expiration, sans ou avec une très faible résistance ou contre-pression dans un espace libre et, pendant la période restante, l'air expiré traverse ledit dispositif initial à l'encontre de l'action d'une résistance ou contre-pression adaptée. De plus, on peut distinguer des parties d'air expiré du flux d'air expiré par regroupement ou détournement de parties correspondant à des fractions ou multiples de l'espace mort estimé de l'individu examiné.

Abstract: A motor cooling and sound absorbing system includes a housing (10) forming a chamber (13) around a motor (11). The shaft (12) of the motor (11) carries a fan (40) positioned in a chamber (38) formed by a recess (36) cut in a foam block (35). The fan (40) draws air into the chamber (13) through inlet apertures (33) in the housing (10) and this air is directed past the motor (11) to cool it. The air exits the fan (40) generally radially against an angled surface (37) of the recess (36) of the foam block (35). The air is then received in a diffuser passageway (41) defined by the angled surface (37) and an angled surface (42) of a choke plate (19) positioned above the foam block (35). The diffuser passageway (41) reduces the velocity of the air to assist the foam block (35) in absorbing the noise generated thereby, while at the same time reducing the pressure at the exit of the fan (40) to increase the cooling air flow past the motor (11). The air then passes from the diffuser passageway (41) to a plenum chamber (43) located above the foam block (35) and out elongate slots (26) formed in the bottom of the housing (10).

Abstract: A system (100) for mitigating intermittent interruptions in an audio radio broadcast system is provided wherein a primary radio signal and a redundant radio signal are transmitted from a transmitter subsystem (120) and received by a receiver subsystem (140). The output (112) of an audio source (110) is coupled to a modulator (160) for modulating a radio frequency signal (162) for coupling to a transmit antenna (172). A second output (114) of audio source (110) is coupled to a delay circuit (116), for adding a predetermined time delay thereto. The delayed audio source signal is coupled to a modulator (164) for modulating a second radio frequency signal (166) that is also coupled to the transmit antenna (172). The receiver subsystem (140) receives both the primary radio signal and the delayed redundant radio signal and couples each to a respective demodulator (180, 182). At least demodulator (180) includes a circuit (181) for determining the degradation in the primary radio signal and provides a quality measurement output signal (186) to a blend control circuit (190). The recovered primary audio signal from demodulator (180) is coupled to a second delay circuit (184), the time delay of second delay circuit (184) being substantially equal to the time delay of delay circuit (116). The audio output from delay circuit (184) and the redundant audio output from demodulator (182) are coupled to a blending subsystem (135), wherein each is combined with a weighting factor and then combined together to form a composite audio signal for coupling to the audio output circuit (150).

Granted: 2011-01-04
Abstract: The invention relates to the use of interferon alpha 5 in the treatment of viral hepatopathies. The invention describes the reduced synthesis of IFN.alpha.5 in the livers of patients with hepatitis C in comparison to healthy livers.  The sub-type of IFN expressed in said healthy livers corresponded only to the subtype alpha 5 in comparison with the different sub-types expressed in ill livers. The sequence SEQ ID NO:l shows the partial sequence of cDNA  corresponding to IFN.alpha.5. These significant differences between the expression patterns of some livers an others demonstrate the importance of the use of such interferon sub-type in the fabrication of compositions useful in the treatment of viral hepatopathies. The invention discloses in details such utilization in different forms and processes, including those which use the production of recombinant proteins from sequences of the type SEQ ID  NO:1.

Title: Process and catalyst/sorber for treating sulfur compound containing effluent
Inventor: WAGNER GREGORY J
IPC: B01J23/56
Filed: 1999-06-16
Granted: 2007-11-13
Abstract: A process and composition are provided for removing contaminants, such as sulfur dioxide and hydrogen sulfide, out of exhaust gases by contacting the contaminated exhaust gas with a catalyst/sorber composition comprising noble metal components and a sorber component, such as oxides of Ti, Zr, Hf, Ce, Al, Si and mixtures thereof, so as to remove the contaminants out of the exhaust gas. The contaminant-loaded catalyst/sorber composition is regenerated via contact with a mixture of an inert gas, such as nitrogen, and a reducing gas, such as hydrocarbons. The catalyst/sorber composition may also contain a modifier, such as Cu, Ag or Bi, which tends to promote the release of the sulfur contaminant off the contaminant-loaded catalyst/sorber composition as sulfur dioxide, rather than the hydrogen sulfide.  The catalyst/sorber composition also promotes the oxidation of carbon monoxide in the exhaust gas.
