  • Publication number: 20090200433
    Abstract: A mounting flange assembly for connecting adjoining exhaust components includes first and second pieces. One flange piece includes at least one first mount hole that extends in one direction and at least one second mount hole that extends in another direction. The first mount hole secures the first piece to one exhaust component and the second mount hole secures the first and second pieces together. Another exhaust component is attached to an opposite side of the first flange piece. The orientation of the first and second mount holes provides a sealed joint between the mating exhaust components while additionally providing improved service access.

  • Patent number: 6913998
    Abstract: Metallic films are grown with a “spongelike” morphology in the as-deposited condition using planar magnetron sputtering. The morphology of the deposit is characterized by metallic continuity in three dimensions with continuous and open porosity on the submicron scale. The stabilization of the spongelike morphology is found over a limited range of the sputter deposition parameters, that is, of working gas pressure and substrate temperature. This spongelike morphology is an extension of the features as generally represented in the classic zone models of growth for physical vapor deposits. Nickel coatings were deposited with working gas pressures up 4 Pa and for substrate temperatures up to 1000 K. The morphology of the deposits is examined in plan and in cross section views with scanning electron microscopy (SEM).

  • Patent number: 6155091
    Abstract: A mandrel assembly is provided for use with a tube bender including a mandrel rod, a mandrel ball, and a coupler. The coupler is configured to couple the mandrel ball to the mandrel rod and includes a link, a first connector member, a second connector member, and a retainer. The link includes a body and a collar. The first and second connector members are positioned to lie over the second end of the body and cooperate to define a groove sized to receive the collar of the link and a socket sized to retain a projection of the mandrel ball. The retainer is positioned to lie over the first and second connector members and the link to secure the first and second connector members to the link.

  • Patent number: 5746634
    Abstract: A process method and system for making field emission cathodes exists. The deposition source divergence is controlled to produce field emission cathodes with height-to-base aspect ratios that are uniform over large substrate surface areas while using very short source-to-substrate distances. The rate of hole closure is controlled from the cone source. The substrate surface is coated in well defined increments. The deposition source is apertured to coat pixel areas on the substrate. The entire substrate is coated using a manipulator to incrementally move the whole substrate surface past the deposition source. Either collimated sputtering or evaporative deposition sources can be used. The position of the aperture and its size and shape are used to control the field emission cathode size and shape.

  • Patent number: 5443062
    Abstract: A load activated oxygen delivery system is configured to deliver oxygen from an oxygen source to a patient through a cannula. The oxygen delivery system includes a precharge chamber for holding oxygen, the precharge chamber having an inlet and an outlet, with the inlet connected to the oxygen source, and a slave chamber providing fluid communication between the cannula and the outlet of the precharge chamber. A diaphragm is positioned to seal the outlet of the precharge chamber to block flow of oxygen from the precharge chamber into the slave chamber. A separate actuating chamber is positioned adjacent to the slave chamber in fluid communication with the diaphragm, with pressure decrease in the actuating chamber relative to the slave chamber causing the diaphragm to move away from the outlet of the precharge chamber, allowing flow of oxygen from the precharge chamber, through the slave chamber, and into the cannula.
