Abstract: A poorly conducting thermal barrier coating applied on a superalloy substrate comprises a mixture of oxides consisting of a composition based on zirconia, 3-15 weight % of an oxide, preferably yttria, that stabilizes the zirconia, 0.5-12 weight % of an additional metallic element selected from Ni, Co, Fe or a mixture of Ni and/or Co and/or Fe, or their oxides, and 0.02-0.1 weight % C. The homogeneous oxide mixture is deposited on the substrate by electron beam evaporation of a bar having a composition consisting of the above thermal barrier coating composition. The mixture can also be applied by thermal or plasma spraying, (plasma-assisted) chemical vapor deposition. A sublayer of nickel-aluminum alloy containing at least one metal selected from Cr, precious metals of crude platinum , yttrium and rare earths can be interposed between the substrate and the oxide mixture layer. Preferably the sublayer has formula MCrAlY, where M = at least one metal selected from Ni, Co and Fe. Independent claims are given for: (a) a superalloy metal piece whose surface is coated at least in part with the thermal barrier; and (b) a process for deposition of the thermal barrier on a superalloy substrate. The deposition process involves (i) mixing and sintering into the form of a bar a mixture of powders of zirconia, a zirconia-stabilizing oxide, and an element selected from Ni, Co and Fe; (ii) introducing the body to into an EB-PVD chamber previously loaded with the bar; and (iii) creating a vacuum in the chamber, preheating the substrate, and focussing an electron beam on the bar in order to vaporize the elements present in the bar so that they condense onto the substrate.   In (i), mixing of the powders is achieved by using a binder comprising a solvent that is at least partially rich in carbon, preferably a polyvinyl alcohol. A thermally crackable, carbon precursor gas selected from methane, ethane, butane, propane, an alkene or alkyne, is introduced into the deposition chamber in the immediate vicinity of the substrate to be coated.

Abstract: Lorsqu'un module initiateur (OM) reçoit des informations, un paquet d'acheminement est formaté sur la base de ces informations. Ledit paquet est transmis à une architecture d'acheminement (RA) destiné à l'acheminer vers un module de destination (DM) désigné par le paquet d'acheminement. La RA interprète le paquet d'acheminement et achemine de manière adaptative ledit paquet vers le DM si bien que le paquet d'acheminement est traité rapidement par le DM. Si la file d'attente du DM est vide et que le DM ne traite pas d'autres paquets, la RA place le paquet d'acheminement dans la file d'attente et le DM lit sa file d'attente pour traiter le paquet d'acheminement. Si un autre paquet d'acheminement est en cours de traitement par le DM, la RA s'adapte en plaçant le paquet d'acheminement dans la file d'attente. Une fois le traitement de l'autre paquet d'acheminement terminé, le DM traite le paquet d'acheminement se trouvant dans la file d'attente. S'il existe déjà un autre paquet d'acheminement en attente dans la file d'attente du DM, la RA s'adapte en créant un autre DM en mémoire pour traiter le paquet d'acheminement. Si le paquet d'acheminement n'est pas traité par le DM dans un laps de temps prédéterminé, la RA s'adapte en envoyant une interruption pour annuler le traitement au sein du DM et garantir que le paquet d'acheminement sera le suivant à être traité. Des éléments correspondant aux composantes de données du paquet d'acheminement peuvent être réorganisés pour présenter un ordre optimisé lors de l'acheminement adaptatif du paquet. Dans l'ordre optimisé, le traitement du paquet d'acheminement est plus rapide.

Abstract: A vascular catheter system (10) comprises a catheter body (18) having a proximal, a distal portion (40, 60), and a single common lumen therebetween. The catheter body includes a first connector (42) secured to the distal end of the proximal portion (40), and a second connector (44) secured to the proximal end of the distal portion (60). The connectors can be selectively connected to each other to join the lumens of the proximal, and distal portions together in a continuous, axially fixed relationship. Disposed within the lumens, when the proximal, and distal portions are joined together, is a drive cable (50).  The drive cable (50) may be movably rotatable about its own longitudinal axis, and carries at its distal end, a work element, which is typically an ultrasonic imaging transducer (56) or intervention device. The lumen carrying the cable will be sufficiently large along a proximal portion to permit preferential collapse of the cable should rotation of the distal end become impeded. The catheter body may be made of a polymer or plastic material, such as polyether ether ketone (PEEK), which provides adequate bonding stiffness, and resistance to kinking from large hoop stresses.

Abstract: A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms. This tie-rod is parallel to a pivot support bar that swings about the fixed post in response to fore-and-aft movement of a speed/direction control lever, the pivot plate being pivotally mounted to the free end of the pivot support bar. Thus, the pivot support bar, first and second crank arms and the tie-rod cooperate to define a four-bar linkage that causes the pivot plate to retain its pivoted position about the second axis during speed/direction control so that such control is made independently of steering, and vice-versa.

Title: Modification of fatty acid metabolism in plants
Inventor: PEOPLES OLIVER P
IPC: C12N1/19
Filed: 1999-03-05
Granted: 2010-06-15
Abstract: Methods and systems to modify fatty acid biosynthesis and oxidation in plants to make new polymers are provided. Two enzymes are essential: a hydratase such as D-specific enoyl-CoA hydratase, for example, the hydratase obtained from Aeromonas caviae, and a .beta.-oxidation enzyme system. Some plants have a .beta.-oxidation enzyme system which is sufficient to modify polymer synthesis when the plants are engineered to express the hydratase. Examples demonstrate production of polymer by expression of these enzymes in transgenic plants.  Examples also demonstrate that modifications in fatty acid biosynthesis can be used to alter plant phenotypes, decreasing or eliminating seed production and increasing green plant biomass, as well as producing polyhydroxyalkanoates.

Abstract: Rotary filtration devices have at least one inner member (36) and at least one outer member (26), which rotate and define a fluid filtration gap (48) therebetween. During filtration, permeate passes from the feed fluid in the gap (48) through the filters (34) facing the gap (48). The inner member (36) has an internal pathway (46) for the flow of feed fluid.      Fluid to be filtered flows from the body of the feed fluid through the internal pathway (46), reverses direction (70), and flows through the filtration gap (48) back to the body of the feed fluid. Alternatively, fluid to be filtered passes from the body of the feed fluid through the fluid filtration gap (48), reverses direction, and flows through the internal pathway (46) back to the body of the feed fluid. The outer member (26) may be closed so that feed keeps circulating in the fluid filtration gap (48) until it leaves through the filter (34) as permeate or reenters the surrounding reservoir (60) of feed fluid.
