  • Patent number: 9645058
    Abstract: A sample encapsulation system includes a base, a chamber having an inlet and a chamber housing in which the chamber is housed. The chamber is fixedly mounted at least in part within the housing and the housing is movably mounted to the base. The system includes a cap, a first ram operably mounted to the cap for engaging the chamber inlet and a second ram positioned in the chamber opposite the inlet. The second ram is movable toward and away from the first ram. The chamber and housing are movable toward the cap for engaging the first ram with the chamber inlet during an encapsulation cycle and away from the cap, disengaging the first ram from the chamber inlet following an encapsulation cycle. The system includes heating and cooling assemblies and a temperature sensor located remotely from the chamber interior to automatically isolate cooling water to the system.

  • Publication number: 20120100780
    Abstract: An abrasive saw having an associated cutting wheel is used for cutting objects. The saw includes a base, a cutting assembly operably mounted to the base and a controller. The cutting assembly includes a pivot shaft, a drive shaft operably mounted to the pivot shaft, a drive, and a drive wheel. A flexible drive element operably connects the drive shaft and a drive wheel. The distance between the drive wheel axis of rotation and the drive shaft axis of rotation is variable to increase or decrease a tension in the flexible drive element. A feed table is operably mounted to the base and is movable forward and rearward in a direction of rotation of the associated cutting wheel. The cutting wheel is lockable in the cutting position and the feed table, with the object secured thereto, is moved, by the controller toward the associated cutting wheel to cut the object.

  • Patent number: 8152603
    Abstract: A slide holder for mounting to a sample holder having a pair of openings therein, for a grinder/polisher includes a plate for receiving the slide. The slide holder includes a pair of stems extending from the plate and configured and spaced for receipt in the sample holder openings. A locking element is mounted to each stem. The locking elements are mounted to pivot eccentrically relative to a center axis of each stem. The stems are inserted into the sample holder openings and the locking elements are pivoted to lock the slide holder to the sample holder and to prevent the stems from disengaging from the sample holder.
