Abstract: A draft sill end casting with a locking center pin is disclosed. The draft sill has an open member with an elongate channel aligned with the central aperture of its center plate. A support shelf is within the elongate channel. A center pin has an upper retainer key supported on the shelf, and the center pin extends through the elongate channel to the exterior of the draft sill. The lower end of the center pin has a slot. When mounted on a truck bolster, a lower retainer key is slid through slots in the bolster walls and through the slot in the lower end of the center pin. The two retainer keys, support shelf and bolster walls lock the center pin in position, limiting axial movement of the center pin and limit rotation of the center pin. Thus, the draft sill and truck bolster are locked together to limit relative vertical and horizontal movement between them. The shelf may include rotation stops to limit rotation of the upper retainer once it is in place. The draft sill includes a key passage so that the upper retainer key and center pin can be removed if desired. In two embodiments, the key passages are through the support shelf and lead to the exterior of the draft sill; in these embodiments, the center pin and retainer key can be removed from the draft sill as a unit. In another embodiment, the key passage is formed as a slot in the interior wall of the draft sill above the support shelf; in this embodiment, the retainer key and center pin must be removed independently of one another.

IPC: B02C7/04
Filed: 2001-03-07
Abstract: A sensor, sensor disk, sensor measurement correction system, and method used in measuring a parameter in the refining zone. The sensor includes a spacer that spaces its sensing element from the disk. In one preferred embodiment, the spacer is made of an insulating material that insulates the sensing element from the thermal mass of the disk to prevent the thermal mass from affecting sensor measurement. The sensor includes a housing carried by the spacer that, in turn, carries the sensing element. Where the sensing element is a temperature sensing element, the housing is thermally conductive and the housing and spacer enclose the sensing element. Each sensor is disposed in the refining surface, preferably in its own separate bore in the disk and flush with or below axial refiner bar height. Signals from one or more sensors are processed by a processing device linked to a module containing calibration data that is applied to make sensor measurements more accurate. The module holds calibration data from sensors that are precalibrated before the sensor disk in which they are assembled is shipped, along with the module, to a fiber processing plant where the disk is installed in a refiner and the module connected to the processing device. In one preferred embodiment the sensor or sensors are carried by a sensor module that can be a removable segment of a refiner disk.
