  • Publication number: 20250198397
    Abstract: A remanufactured yoke for a fuel pump includes a body having a base and a sidewall extending orthogonally from the base. The base and the sidewall together define a receiving space. The sidewall defines an inner surface facing the receiving space and an outer surface opposite the inner surface. The remanufactured yoke also includes a wear plate removably disposed within the receiving space defined by the base and the sidewall. The wear plate is in contact with the base of the body. The remanufactured yoke further includes a coupling member coupled with the body and the wear plate to prevent a rotational movement of the wear plate relative to the body.

  • Patent number: 9672469
    Abstract: An apparatus and method to increase accuracy in individual attributes derived from anonymous aggregate data uses aggregation keys in order to retrieve distribution sets and generate best-effort results for individual attributes. Multiple aggregation keys may be utilized to which individual attributes may be cross-mapped. The aggregation keys may be divided into location-based aggregation keys and name-based aggregation keys. The resulting data may be of varying granularity depending upon the granularity of the aggregation key used for the distribution and to generate the attributes.

  • Publication number: 20160288278
    Abstract: A heat exchanger assembly process and system are disclosed. The assembly method may include positioning a core for assembly, the core having a plurality of tubes. The method may also include pressurizing the core by increasing the pressure of a fluid within each of the plurality of tubes to a threshold pressure. The method may further include moving the pressurised core into an interior space of a housing.

  • Publication number: 20110047933
    Abstract: A profiled deck is roll-formed from a steel sheet to define at least one pair of crests, a stiffener upstanding from the surface of each crest, a trough positioned between the or each pair of crests, and inclined webs extending between the sides of the trough and the neighbouring sides of the crests. The boundary between each web and crest defines a corner which has a smooth curvilinear profile and the elemental compression width of each crest is no more than four times the elemental compression width of the respective stiffener. Furthermore, the radius of each curvilinear corner is not less than 33 mm.
