  • Publication number: 20190063021
    Abstract: A work attachment for a motor grader includes a moldboard and a trip edge assembly coupled to the moldboard. The moldboard defines a plurality of first apertures. The trip edge assembly includes a trip edge structure. The trip edge assembly also includes a pivoting mechanism for pivoting a portion of the trip edge assembly in a first direction with respect to the moldboard when the trip edge assembly encounters an object in a drive path of the motor grader. The trip edge assembly further includes a mounting structure defining a plurality of second apertures. The plurality of second apertures are aligned with the plurality of first apertures to receive mechanical fasteners for removably coupling the trip edge assembly with the moldboard.

  • Publication number: 20160215814
    Abstract: An assembly for a ball joint is provided. The assembly includes a housing assembly having a first section and a second section. Each of the first and second sections includes a concave spherical portion having a channel and an aperture. Each of the first and second sections includes a flange extending outwardly from sides of the concave spherical portion. The flange includes an aperture for receiving a fastener. The concave spherical portion of the first and second sections defines a ball seat. The apertures defined in the flange are axially aligned to connect the first and second sections through the fastener. The assembly includes an insert having a partial hemispherical shape configured to rest in the concave spherical portion. The insert includes a protrusion configured to mate with the channel. The insert includes a groove having an aperture axially aligned with the aperture in the channel to receive a lubricant.

  • Patent number: 7774209
    Abstract: A method for issuing both a virtual card and a physical card to a cardholder comprises issuing a virtual card to a cardholder, with the virtual card comprising an identifier and an associated database record of a stored value. A physical card is also issued to the cardholder. The physical card includes an identifier that is different from the virtual card identifier, and the physical card is in an inactive state until the physical card is activated by linking of the physical card identifier to the database record of the stored value.

  • Patent number: 6498843
    Abstract: Methods and systems consistent with the present invention intercept and monitor signals of any type associated with a target telephone number in a communications network such that the interception and the monitoring are undetectable. Such methods and systems configure a network by provisioning a route to a collection node in the network, defining a first trigger for intercepting a signal associated with the target telephone number, and by defining a second trigger for routing the intercepted signal on the provisioned route to the collection node. The methods and systems then monitor the signal at the collection node by intercepting the signal based on the first trigger and routing the intercepted signal to the collection node based on the second trigger.

  • Patent number: 4550389
    Abstract: A magnetic domain device has at least one post element formed from a material that exhibits magnetic domain characteristics and that is positioned on a nonmagnetic substrate material. A pair of electrical drive lines associated with a post element permit coincident current selection of the post element to nucleate a magnetic domain reversal, and an additional current introduced into an adjacent drive line establishes an additive magnetic field to assist the propagation of a domain wall associated with the nucleated magnetic domain reversal so that the direction of magnetization of the post element is reversed.
