Abstract: A processing machine (10) for building an object (11) from powder (12) includes a build platform (434A); a powder supply assembly (418); and an energy system (22) that melts the powder (12) on the build platform (434A) to form the object (11). The powder supply assembly (418) can include (i) a first container region (444A) that retains the powder (12) prior to distribution onto the build platform (434A); (ii) a supply outlet (439) positioned over the build platform (434A); (iii) a flow control assembly (442) that selectively controls the flow of the powder (12) from the first container region (444A) to the supply outlet (439); (iv) a second container region (446A) that retains the powder (12) for refilling the first container region (444A); and (v) an actuator system (448) that urges powder (12) from the second container region (446A) to fill the first container region (444A).

Abstract: Records received from one or more sources in a network are processed. For each of multiple intervals of time, a matching procedure is attempted on sets of one or more records, including comparing identifiers associated with different records to generate the sets and determining whether or not a completeness criterion is satisfied for one or more of the sets. The processing also includes, for at least some of the intervals of time, processing at least one complete set, consisting of one or more of the received records on which the matching procedure is first attempted during the interval of time and one or more records stored in a data store before the interval of time, and for at least some of the intervals of time, processing at least one incomplete set, consisting of one or more records stored in the data store before the interval of time.

Abstract: A fuel pump module for installation between top and bottom walls of a fuel tank. The housing defines a space accommodating a pump. The fuel pump module includes a mounting component coupled to the housing. The mounting component includes a first surface, a second surface opposite the first surface and facing the housing, a first end, and a second end opposite the first end. The mounting component and the housing are joined with a spring-loaded coupling such that the mounting component is urged away from the housing. The mounting component further includes a U-shaped recess that is concave on the first side of the mounting component. The bottom side of the housing forms a first distal end of the fuel pump module for engaging the bottom wall. The first surface of the mounting component forms a second distal end of the fuel pump module for engaging the top wall.

Abstract: A method includes determining a first quantity of data records of a group of data records from a stream of data records received by an application having a plurality of modules. The method includes, for one or more of the modules of the application, determining a respective second quantity of data records output by the module during processing of the group of data records. The method includes determining whether the first and second quantities of data records satisfy a rule. The rule is indicative of a target relationship among a quantity of data records received by the application and a quantity of data records output by one or more modules of the application.

Abstract: An integrated solar roofing system for installation on a roof surface and for converting solar energy into electrical energy. The system comprises a first row of photovoltaic (PV) roofing tiles having a plurality of electrically interconnected PV cells. The roofing tiles comprise a first tab that extends from the tile base and has at least one mounting hole. The first tab exposes a first electrically conductive material on the first side of the first tab. The roofing tiles further comprise a second tab located on the second side of the tile base and having at least one mounting hole extending through the second tab and tile base. The second tab exposes a second electrically conductive material on the second side of the tile base. The first tab of each roofing tile in the first row is at least partially superposed over the second tab of an adjacent roofing tile aligning the mounting holes so that the roofing tiles are in electrical series communication along the first row.

Abstract: A spark plug derives an extended lifetime because a large plurality of sharp edges are provided on the center electrode, the ground electrode, or both to enhance spark propagation. In a first embodiment, the ground electrode has a conventional cantilever shape, but the center electrode extends into coplanar relation to a distal surface of the electrode so that sparks propagate from the cylindrical side walls of the center electrode. In variations of the first embodiment, the number of cantilevered ground electrodes is increased, with the ground electrodes being circumferentially and equidistantly spaced about the center electrode. In another embodiment, the ground electrode has an annular configuration and includes a cylindrical annular wall spaced radially outwardly of the cylindrical sidewall of the center electrode, in concentric relation to the center electrode.
