    Abstract: An automatic closure is disclosed which is adapted to block the flow of air through a door opening. The closure comprises a pliant curtain supported by its upper edge and by a portion of one side edge. The curtain includes a pocket which contains a bracing panel supported by the flanges of a pair of mutually perpendicular split sleeves. The sleeves are secured to a rotatable post, which normally assumes a preferred rotational position corresponding to the air-blocking position of the curtain in the door opening. The curtain, which also carries weights to facilitate its movement into and out of the latter position, is readily installed on, or removed from, its supporting structure.

    Abstract: A U-shaped frame is secured to a pair of spaced fence posts, and the frame has yoke members which secure the U-frame at the top and the bottom to the fence posts. A one-way gate or turnstile is provided by rotatable members on the U-frame having turnstile arms. A means of removably securing the U-frame to the fence posts is in the form of members securing the fence posts which can be manually tightened. The entire turnstile is designed to be readily removable from the fence line or readily insertable in a fence line; if the fence posts to which it is attached are weak, the U-frame tends to strengthen them.

    Abstract translation: U形框架固定到一对隔开的栅栏柱上，框架具有将U形框架顶部和底部固定到栅栏柱的轭构件。 单向门或十字门由在具有旋转门的U形框架上的可旋转构件提供。 将U形框架可移除地固定到挡板柱的装置是固定可以手动拧紧的围栏柱的构件的形式。 整个十字转门设计成可以方便地从栅栏线上移除或容易插入栅栏; 如果连接的栅栏位置较弱，则U框架往往会加强。

    Abstract: An overhead door for the vertical opening of a truck trailer comprises a plurality of panels connected together by hinges, which extend the width of the panels and are confined within the panel. The panels, which are preferably formed of plastic, are counterbalanced by a spring, which is movable with the panels. The spring is wound by gears, which are connected thereto, cooperating with racks on the horizontal portions of the tracks on which the panels are movably supported. The bottom panel is locked to the trailer body by a locking mechanism, which is carried by the lowermost panel and cooperates with locking pins on the mounting angles on which the vertical portions of the tracks are supported.

    Abstract: A gate slidable along and pivotal on a stanchion carries a roller engaging a cam surface on a cam block to close the gate and stop the gate in a closed position. The block is rotatable on the stanchion and is connected by torsion rods to a collar fixed to the stanchion.
