Abstract: An apparatus for reducing the vulnerability to unauthorized entry past a r comprising a first rectangular shaped plate attached to the outside of the door, the first plate having a second or strike plate positioned to extend into the door frame to resist separation of the door and its door frame when the door is closed. The apparatus further comprises a third rectangular shaped plate attached to the inside of the door and communicating with the first plate. A portion of the first plate extends beyond the door covering a portion of the door frame. The apparatus is adapted to receive a door locking mechanism having a dead bolt. When the door is in a closed position and the dead bolt is activated, the dead bolt is extended through a pair of apertures in the door frame. Extending the dead bolt through the pair of apertures in the door frame reinforces the door and door frame and places all applied loads during forced entry directly to the dead bolt via double shear.

Abstract: A floating roof tank is provided having a fixed vertical pole disposed through an opening in the floating roof. The vertical pole serves as both a gauging pole and an anti-rotational pole. The gauging pole is perforated to allow the free flow of liquid into and out of the gauging pole. A float is disposed within the gauging pole. The float has a pair of spaced-apart seals which effectively prevent the escape of vapor from within the tank through the gauging pole. Other seals effectively prevent the escape of vapor from within the tank around the periphery of the gauging pole and around the periphery of the roof itself. The gauging pole, in combination with the double sealed float, provides the operator of the tank with the ability to sample the tank from the top of the gauging pole, rather than having to stand on the floating roof itself.

Abstract: The top and bottom felts at the web transfer between two dryer sections in a single tier papermaking dryer are spaced by pivoting the vacuum roll over which the felt and web move. The vacuum roll is mounted to two pivot arms which are driven by inflatable air rides to alternately incline the roll toward the downstream felt, forming a sandwich of the two felts and the web, and to a spaced position. The short motion of the vacuum roll allows standard felt stretchers to be used, and permits rapid adjustment of the felt spacing.
