Abstract: A two-piece grab arm housing for a grapple mechanism useable on a grapple attachment is described. The grab arm housing includes a lower arm housing with grab arms mounted to the lower arm housing, and an upper arm housing mounted to the lower arm housing. The upper arm housing and the lower arm housing are movable relative to one another in an x-direction and are moveable together in a y-direction perpendicular to the x-direction. In addition, the upper arm housing includes an opening through which a main beam of the grapple attachment can extend.

Abstract: A system and method are disclosed for measuring signal crosstalk in an electronic circuit device or Integrated Circuit (IC) device, correlating the results with modeled information, and accurately identifying one or more levels of coupling noise in the device. For example, a system is disclosed that provides data on levels of crosstalk between conductive lines in a device. The system uses programmable victim and aggressor lines, programmable drive capability, and programmable loading through one or more known crosstalk structures to compare an output signal with a reference signal and accurately identify one or more levels of coupling noise in the device. An external reference signal can be used to detect upsets or crosstalk in the device. As such, using such programmability features of the system, numerous combinations of coupling in a device can be measured at a time.

Abstract: A top dresser (10) includes sheeting (70) in the form of an endless belt passing around first and second drums (148, 160) and a bed (166) including a plurality of rollers (106). Continuous V-shaped guides (122) are received in pulleys (120) on the drums (148, 160) for tracking the endless belt. A blocking device (112) in the form of a rod is slid in the mid-frame (102) to prevent the shafts (108) of the rollers (106) from axially sliding against their bias from their operative positions to their installation positions. Ledges (116) having friction reducing strips (118) extend over the shafts (108) of the rollers (106). A compound gear (180) in gearing relation with the second drum (160) and in driving relation with a spindle (82) of a brush (74) is rotatably mounted to an arm (174) pivotally mounted to the second drum (160). The spindle (82) includes two portions (82a, 82b) removably connected by a coupler (76), with the first portion (82a) being cantilevered supported from the side frame (100).
