Title: Reduction of nox emmisions from gasoline engines
Inventor: HOLLRAH DON P
IPC: C10L1/30
Filed: 1992-03-09
Abstract: Case EI-6324 REDUCTION OF NOx EMISSIONS FROM GASOLINE ENGINES                Abstract of the Disclosure NOx emissions are reduced in two stages during operation of an engine equipped with an exhaust gas catalyst system. In the first stage, a reduction in NOx emissions is effected in the exhaust leaving the combustion chamber. In the second stage a further reduction in NOx emissions is effected in the exhaust passing through the exhaust catalyst system. Both of the two-stage reductions are brought about in the same way, namely (a) by use of a suitable fuel composition containing at least one fuel-soluble cyclopentadienyl manganese tricarbonyl compound in an amount equivalent to up to 1/32 gram of manganese per gallon of fuel; and b) by enhancing the NOx control activity of at least the catalyst by prior operation of the engine on such fuel composition, either intermittently or continuously. Such prior operation constitutes a run-in or conditioning stage of sufficient total duration (continuous or interrupted) so that substantial reductions in NOx emissions are thereafter continuously achieved in subsequent operations of the engine. The efficacy of the invention are demonstrated by conducting a fleet test involving 48 cars, each operated for 75,000 miles during the test. Dramatic reductions in NOxwere achieved. Moreover, no significant catalyst pluggage, or increase in exhaust gas back pressure, or adverse effect upon oxygen sensors were experienced in thefleet test.

Filed: 1992-07-29
Abstract: PROCESS AND APPARATUS FOR             MONITORING SUPERSATURATION               Abstract of the Disclosure A process and apparatus for precipitating a silver halide emulsion is disclosed.  The process is comprised of the steps of adding silver ions to a dispersing medium containing halide ions within a reaction vessel to initiate growth of silver halide grains within the dispersing medium, monitoring the temperature of the dispersing medium to establish the equilibrium solubility product constant of silver and halide ions within the dispersing medium; concurrently, using a reference electrode and a first indicator electrode, monitoring the halide ion activity within the dispersing medium; and adjusting the level of dissolved halide ion in the reaction vessel to maintain a stoichiometric excess of halide ions, based on the equilibrium solubility product constant.  In the process the potential difference between a silver ion specific electrode in contact with the dispersing medium within the reaction vessel and at least one of the first indicator electrode and the reference electrode is concurrently monitored to allow the level of dissolved silver ion to be determined independently of the equilibrium solubility product constant, and the level of dissolved silver ion in the dispersing medium is adjusted based on the potential difference to maintain a selected profile of dissolved silver ion during silver halide grain growth.  The apparatus contains the elements necessary for the practice of the process.

Title: Impeller system for a gas turbine engine
Inventor: NARAYANA ANAND D
IPC: F01D5/08
Filed: 1992-09-09
Abstract: Docket No. 13DV-10807 Abstract An interstage thermal shield assembly for a gas turbine engine.  The assembly includes an axially-extending thermal shield positioned between first and second stage disks to form a seal therebetween.  The thermal shield includes complementary hook members shaped to engage slotted hook members formed on the first stage disk to form a bayonet connection, and complementary lip members for engaging lobe members formed on the second state disk by means of split rings, thereby eliminating the need for a bolted connection between the thermal shield and disks and facilitating attachment and removal of the thermal shield.  The thermal shield includes an annular impeller which is positioned rearwardly of the first stage disk, the impeller including bayonet connection with the disk which restrains the impeller from axial deflection, but permits radial deflection in response to thermal changes.  The thermal shield also includes an annular bore, attached to and extending radially inwardly from the thermal shield, and rotating in a plane substantially normal to a rotational axis of the shaft mounting the disks.  The bore is shaped to have a center of mass out of the plane of rotation, so that rotation of the bore creates a moment which urges the bore to deflect toward the upstream disk, thereby compensating for a pressure differential across the face of the bore as cooling air is pumped by the impeller radially outwardly toward the end of the first stage disk.
