  • Publication number: 20170176606
    Abstract: A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. In the method and apparatus, a polymer matrix of a transparent polymer and nanoparticle scintillators is placed on top of a collimated bundle having a plurality of capillaries and pressed in a pressure vessel until the polymer matrix is forced into the capillaries. Pressure is applied via an anvil on top of the polymer matrix. To prevent fracturing of the collimated bundle during pressing, back pressure is supplied to the pressure vessel via a valve, which controls a supply of high pressure gas. Alternatively, the back pressure may also be supplied by a press (and or pressure) and support to the collimated bundle is provided by a high melting point thermoplastic. Heat may be applied to the polymer matrix via the anvil to speed the pressing operation due to the viscosity of the polymer.

  • Patent number: 6199935
    Abstract: A load-carrying box on a land vehicle in the form of a generally rectangular container having an upper perimeter defined by a top edge of each of the walls encompassing an open top is covered by a flexible sheet cover having a first end secured adjacent a top edge of one of the side walls. A second end of the flexible sheet is attached to a roller having opposite ends projecting beyond the top edges of two end walls forming the load-carrying box. A motor is coupled to the roller for rolling and unrolling the flexible sheet cover along the top edges of the two end walls and along bows connecting the two side walls. An arm has a first end coupled to the roller and a second end including a slot engaging a pin defining a pivot for the arm so that the roller can remain in constant contact with the top edges of the end walls and bows as the flexible sheet cover is deployed and retrieved.
