Filed: 1997-11-25
Abstract: A reactor that can be attached to the exhaust manifold of an internal combustion engine to oxidize and burn carbon soot particles, carbon monoxide, and unburned hydrocarbons, and to dissociate nitrogen and sulfur oxides. The reactor has a reaction zone (20) that contains porous heat-retaining foam cells (30) and that is bounded by a porous heat-retaining zone (4), which in turn is surrounded by ceramic insulation materials (6, 7) to minimize energy losses. Engine exhaust (1) at elevated temperatures and containing some oxygen (air) enters the reaction zone (20). By impinging heat transfer, thermal radiation enhancement, energy trapping and combustion of engine emissions, temperatures sufficient to oxidize carbon soot particles, carbon monoxide, and unburned hydrocarbons are attained. Steam or atomized water droplets (104) are introduced to improve the efficiency of the reactor through gasification, regasification, water shift reactions, methanation, and hydrocracking reactions. Harmless product (12) of the oxidation reactions, H2O and CO2, are released from the reactor.

Abstract: On traite la presbytie par implantation d'une prothèse, dotée d'un élément de base allongé, dans plusieurs poches allongées formées dans le tissu de la sclérotique transversalement par rapport à un méridien oculaire. L'élément de base allongé possède une surface interne conçue pour être placée en contact avec la paroi interne de la poche et une arête sur la surface interne de la base s'étendant le long d'au moins une grande partie de la longueur de la base. L'effet combiné de la prothèse implantée exerce une traction radiale vers l'extérieur sur la sclérotique, dans la région recouvrant le corps ciliaire qui dilate la sclérotique dans ladite région en même temps que le corps ciliaire sous-jacent. La dilatation du corps ciliaire restaure la distance de travail efficace du muscle ciliaire de l'oeil presbyte et de ce fait accroît l'amplitude de l'accommodation. On peut traiter l'hypermétropie, le glaucome primaire à angle ouvert et/ou l'hypertension en augmentant la distance de travail efficace du muscle ciliaire.

Filed: 1999-02-26
Abstract: Matériau isolant constitué essentiellement d'alumine et présentant une teneur Na comprise entre 0,07 et 0,5 % en poids exprimée en terme de Na¿2?O. Cette teneur Na est relativement élevée et est habituellement considérée comme étant absurde. La résistance d'isolation à haute température et la résistance mécanique sont loin d'être faibles. Le matériau présente un bon rendement comparé à celui de matériaux isolants classiques présentant des teneurs Na inférieures à celle du matériau de l'invention. Ainsi, à la place d'alumine classique à faible teneur en soude, l'alumine à teneur en soude intermédiaire ou l'amine à forte teneur en soude utilisées sont beaucoup plus coûteuses. Le coût de production d'un isolant (2) pour bougies d'allumage et également le coût de production d'une bougie d'allumage (100) constituée de celui-ci peuvent être réduits considérablement.

Title: Liquid extraction machine and method for cleaning floor surfaces
Inventor: FULGHUM TRENT A
IPC: A47L11/20
Filed: 2000-02-22
Abstract: An extraction machine for cleaning a floor surface, such as carpeting, has a cleaning solution dispenser capable of dispensing a cleaning solution onto the surface being cleaned and a diluting solution dispenser capable of dispensing a diluting solution onto the floor surface. The diluting solution is substantially different from the chemical cleaning solution. A recovery system is included for extracting a dirty solution from the floor surface. The cleaning solution dispenser, diluting solution dispenser and recovery system are arranged on the extraction machine relative to each other such that as the extraction machine is moved over a segment of the floor surface in a forward direction of travel of the machine, the cleaning solution dispenser passes over the segment prior to the diluting solution dispenser, dispensing cleaning solution to promote the removal of dirt from the floor surface segment. The diluting solution dispenser then passes over the segment of floor surface to promote suspension of the chemical solution and dirt in the diluting solution thereby forming the dirty solution. Finally, the recovery system passes over the segment of floor surface to extract the dirty solution from the floor surface, thereby leaving a cleaned floor surface.
