Abstract: An integrated two-step process for producing low-cost atmospheres suitable for annealing ferrous and non-ferrous metals and alloys, brazing metals, sealing glass to metals, and sintering metal and ceramic powders in continuous furnaces from non-cryogenically produced nitrogen containing up to 3% residual oxygen is disclosed. The residual oxygen present in non-cryogenically produced nitrogen is converted to moisture by mixing it hydrogen and passing the mixture through a reactor packed with a platinum group catalyst in the first step of the process. The reactor effluent stream containing a mixture of nitrogen, unreacted hydrogen, and moisture is mixed with a pre-determined amount of a hydrocarbon gas and introduced into the heating zone of a continuous furnace in the second step of the process to 1) convert moisture to a mixture of carbon monoxide and hydrogen by reaction with the hydrocarbon gas via water gas shift reaction and 2) produce atmospheres in-situ suitable for heat treating. The key features of the process include 1) use of economical amount of hydrogen to convert residual oxygen to moisture in an external catalytic reactor and 2) conversion of moisture to a mixture of carbon monoxide and hydrogen by reaction with the hydrocarbon gas via water gas shift reaction in the hot zone of a continuous furnace. The disclosed process is particularly suitable for producing low-cost heat treating atmospheres for continuous furnaces operated at 700°C and above.

Abstract: A cleaning system for increasing the packing density of a sump fill. The cleaning system has a blade having an acute angle for removing residual particles from the photoreceptor surface. The acute angle of the blade creates a build up of toner and other residual particles on the cleaning blade.

Title: Instrumentation and method for evaluating clot elastic modulus, force development and erythrocyte flexibility during clotting and dissolution
Inventor: CARR MARCUS E JR
IPC: G01N33/49
Filed: 1993-01-15
Granted: 2004-04-20
Abstract: Intermittent application and removal of a compressive force on a blood sample (8) positioned between a pair of plates (12 and 14) throughout clot formation and dissolution provides a standard for using voltage output from a transducer (22) to determine force and elastic modulus parameters. Force development arises from the internal actions of the platelets during clot retraction. Elastic modulus provides a measure of the stiffness of the clot.  Clotting can be measured as an increase in force development and clot elastic modulus. Clot dissolution can be determined by a dramatic decrease in force development and in elastic modulus. Providing the blood sample with a clot dissolving agent such as tPA  allows determining the fibrinolytic potential of whole blood and, thus, aids in identifying patients at risk for thrombosis due to a decreased ability to dissolve clots. Clot elastic modulus provides a measure of erythrocyte flexibility.

Abstract: Un système (14) régulateur de vitesse de croisière comprend un radar (32) monté sur le véhicule et permettant de déterminer la distance et la vitesse d'approche du véhicule par rapport à une cible se trouvant devant ce dernier. La distance et la vitesse d'approche sont utilisées pour déterminer une nouvelle vitesse consignée pour le régulateur, laquelle peut être inférieure, mais non supérieure à la vitesse introduite dans le régulateur de vitesse par le conducteur du véhicule. La nouvelle vitesse consignée est choisie de façon que le véhicule ne puisse pas dépasser la cible, et permet de réduire idéalement la vitesse d'approche à une valeur nulle à une distance minimale prédéterminée de la cible. Le système détermine également des déplacements progressifs du papillon du véhicule au moyen d'une augmentation de gain choisie, tout en étant conçu pour réduire au minimum les saccades produites par l'actionnement du papillon. Si la cible se déplace hors de la trajectoire du véhicule, ou accélère, le système s'adapte en conséquence et permet éventuellement au véhicule de retrouver la vitesse introduite à l'origine dès que possible.

Abstract: Vapors of elemental mercury and mercury compounds contained in a hot combustion gas stream are removed therefrom by oxidizing the elemental mercury, to form a mercury compound, and adsorbing the mercury compounds on adsorbent particles such as activated alumina. Oxidation is catalytically promoted. After adsorbing a substantial quantity of mercury compounds, the spent adsorbent particles can be regenerated and re-used by heating the particles to decompose and drive off the mercury compounds. In another embodiment, oxidation of the elemental mercury is catalytically promoted at a catalyzing station, and the mercury compounds are removed from the gas stream by scrubbing.
