  • Patent number: 9631773
    Abstract: A shipping container for shipping thermally active materials includes a plurality of structural panels that define a container interior, and are configured for receiving the thermally active materials. The container also includes an exterior disposed adjacent to an environment in which the shipping container is disposed. A thermal barrier member is placeable between the thermally active materials and the environment in which the container is placed. The thermal barrier includes a thermal barrier interior panel and a thermal barrier external panel defining a heat absorbing material receiving cavity. A flowable polymer based heat absorbing material is disposed within the heat absorbing material receiving cavity. The thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed.

  • Patent number: 4497461
    Abstract: A snubber (12) includes a fixed member (14) and a movable member (16). A variable volume chamber (20) is defined between these two members (14, 16). The chamber (20) includes an orifice (22). A body of extrusible material (26) substantially fills the chamber (20). A rotary actuator (6) carries a lug (28) that contacts the movable member (16) when the actuator (6) moves beyond a predetermined position. This contact pushes the movable member (16) against the extrusible material (26) to decrease the volume of the chamber (20) and to cause the extrusible material (26) to be extruded through the orifice (22). This stops the rotation of the actuator (6) and absorbs its kinetic energy. The snubber (12) is supported by a frame member (10). Preferably, the frame member (10) has a cavity (40) into which material extruded through the orifice (22) is received.

  • Patent number: 4475436
    Abstract: A rotatable support mounts a plurality of missile carrying missile launchers for rotation about a center axis. Each launcher mounts a plurality of missiles for rotation about an axis. The rotatable support is rotated to successively bring each missile launcher into a launch position. Each such launcher is rotated to successively bring each missile carried by it into a launch position.
