  • Patent number: 7159579
    Abstract: An emissions control canister including an insert tube and a final scrubber inside the tube. Because a scrubber formed as a carbon monolith is relatively fragile and easily damaged, a flexible, porous, resilient sling is provided for installing and retaining scrubber within cylindrical tube in lieu of either seals or elastomeric gaskets. An end of the scrubber is placed on a center portion of the sling, and the straps are folded alongside the cylindrical surface of the scrubber to form a sub-assembly. The sling is die-cut from planar stock of either a loose, thick, woven polyester fabric or an open-cell resilient foam. Advantages of the sling over a resilient elastomeric gasket are cost, ease of assembly, and the outer surface of the scrubber is made available as additional vapor adsorption area.

  • Patent number: 7161461
    Abstract: A trim resistor assembly includes a trimmable resistor element embedded within a polymeric housing. The trimmable resistor element includes trimmable resistive film disposed on a nonconductive substrate. Lead wires are connected to contact pads on the substrate. The resistor element and wires are pre-assembled and placed within a mold defining a cavity. The mold includes a pedestal that covers a central region of the substrate that includes the trimmable resistive film. A polymeric material is injected into the cavity to form an integrally molded body that is the polymeric housing. In addition to the trim resistor element and the bare end sections of the wires, the section of the wires that are adjacent the end sections and include the polymeric sheath are also embedded in the housing to strengthen and seal the joint. The pedestal forms an opening in the housing that exposes the resistive film to provide access for trimming the resistance to a desired value.

  • Patent number: 7159845
    Abstract: A bearing module for a pintle valve including a pintle bearing, bearing spring, and two-part housing. The bearing has an axial face for sealing against an inner axial surface of the housing. The bearing diameter is less than the diameter of the housing, permitting the bearing to float radially. The housing fits into a port in the valve body and also extends over an axial surface of the body, thus forming a seal against the wall of the port and the surface of the body. The bearing spring, preferably a wave washer, is compressed within the housing as the two housing parts are assembled to form the module. In a currently preferred embodiment, the housing further comprises a coking shield extending along the surface of the pintle shaft within the valve port to reduce the tendency for coking gases to enter the bearing module.

  • Patent number: 7159569
    Abstract: A precision fuel rail assembly for direct fuel injection comprising a plurality of formed parts first assembled and positioned loosely on a precision fixture, then joined (e.g. tack welded), by applying a BFM on all joints forming a “green” assembly and firing in a brazing oven, to produce a precision assembly formed from stainless steel parts. A bracket defining a sole plate for the assembly may be formed as a continuous element or a plurality of individual fuel rail brackets. Flanged sockets are attached to the bracket at locations corresponding to the fuel injector locations on an engine bank. Bolt holes are provided along the centerline of the sockets and fuel injectors. The bracket supports a fuel distribution tube via saddle elements disposed between the bracket and the tube. A jump tube supplies fuel from the distribution tube to each socket.

  • Patent number: 7154291
    Abstract: A method and apparatus for measuring current, and particularly bi-directional current, in a field-effect transistor (FET) using drain-to-source voltage measurements. The drain-to-source voltage of the FET is measured and amplified. This signal is then compensated for variations in the temperature of the FET, which affects the impedance of the FET when it is switched on. The output is a signal representative of the direction of the flow of current through the field-effect transistor and the level of the current through the field-effect transistor. Preferably, the measurement only occurs when the FET is switched on.

  • Patent number: 7147366
    Abstract: The rationality of a measured temperature of transmission fluid is assessed by comparing it to an engine coolant temperature. The rationality assessment is enabled when the ambient air temperature is reliably determined and deemed normal, a sufficient soak condition is confirmed, and the measured temperature, the engine temperature and the ambient air temperature are all within prescribed ranges. The rationality assessment monitors the ambient temperature relative to the initial engine temperature during the assessment period, and the assessment is disabled if the ambient air temperature deviates from the initial engine temperature by more than a calibrated value.

  • Patent number: 7147953
    Abstract: A fuel cell assembly comprising a plurality of individual fuel cells, especially a solid-oxide fuel cell assembly. The cells are organized into a plurality of stacks, preferably two stacks, disposed side-by-side rather than end-to-end as in a prior art monolithic single stack. This arrangement makes the assembly compact physically, which can be highly desirable in some fuel cell applications. The stacks are connected conventionally in series electrically but are supplied with air and fuel in parallel to shorten the distribution manifolds and improve uniformity of distribution and exhaust among all the cells.

  • Patent number: 7144644
    Abstract: In a solid-oxide fuel cell assembly, at least one positive displacement air supply (PDAS) pump supplies at least a portion of the air required for various functional air streams through the assembly. Mass air flow through each PDAS pump is readily controlled to a predetermined flow by controlling the rotational speed of the pump, obviating the need for an MAF sensor and control valve. Preferably, each different air stream through the assembly is controlled by its own PDAS pump, sized for the required flow, allowing each to operate at its optimal pressure and thereby minimizing the parasitic electrical cost of providing air to the SOFC assembly.

  • Patent number: 7143995
    Abstract: A motorized cam actuator for linear actuation of an apparatus. An actuating motor shaft is fitted with a bushing having first and second opposed flats and a threaded portion at an outer end thereof. With the motor mounted to a pedestal, the bushing is rotated on the shaft to a predetermined angular position such that assembly stack up is cancelled. The bushing is then fixed to the shaft by welding. A cam with a central opening is mounted onto the bushing, the opening having flats for mating with the flats on the bushing. The cam is mounted onto the bushing and is secured thereto by a nut. This arrangement eliminates any relative motion between the bushing and the motor shaft and prevents stress on the weld joint from reaching failure levels.

  • Patent number: 7131766
    Abstract: A temperature sensor includes a membrane supported by a substrate and a circuit having elements for a substrate electrical resistance indicative of the temperature of a substrate and a membrane electrical resistance indicative of the temperature of a membrane. The substrate resistance and the membrane resistance are arranged in a bridge configuration to facilitate measurement of a differential voltage responsive to temperature change. The resulting temperature signal includes a first varying portion and a second varying portion. A controller receives a temperature signal from sensor, eliminates the second varying portion and generates a temperature value based on the based on the first varying portion. In this manner, the sensor provides an improved, fast response to changes in the surrounding temperature.
