摘要： A template according to the invention is configured for manual testing of a mail piece to determine if the dimensions and stiffness of the mail piece are acceptable for passage through an associated automated mail sorting machine. The template includes a frame having a pair of spaced, curved walls defining a curved test slot. The curved slot has an open end through which a mail piece can be inserted and a removal opening for removing the mail piece from the slot. The removal opening in a preferred embodiment comprises a lengthwise slot in one of the curved walls through which the mail piece can be manually held and pushed back out of the open end of the template. The template may include a bracket for mounting the template on a secure surface.

摘要： A tensioning device configured for use in a conveyor system as an idler roller over which a belt is wound under tension includes a housing, an arm mounted in the housing for linear movement in and out of the housing, a roller mechanism mounted at a distal end of the arm including a roller configured for rolling contact with a belt of a conveyor system, and an actuator for extending and retracting the arm from the housing. The actuator includes a worm shaft and a lead screw. A pinion of the worm shaft engages a gear affixed at one end of the lead screw. The tensioning device includes a coupling by which rotation of the lead screw results in outward movement of the arm when the worm shaft is rotated in a first direction, and which results in inward movement of the arm when the worm shaft is rotated in the opposite direction. Engagement of the worm shaft to the gear is self-locking.

摘要翻译： 一种构造成用作传送系统的张紧装置，其中带状物在张力下被缠绕在其上，所述惰轮包括壳体，安装在壳体中用于线性运动进出壳体的臂，安装在远端的滚子机构 所述臂包括构造成用于与输送机系统的带滚动接触的辊，以及用于从所述壳体延伸和缩回所述臂的致动器。 致动器包括蜗杆轴和导螺杆。 蜗杆轴的齿轮接合固定在丝杠一端的齿轮。 张紧装置包括联接器，当蜗杆轴沿第一方向旋转时，引导螺杆的旋转由此引起臂的向外运动，并且当蜗杆轴沿相反方向旋转时导致臂向内移动 。 蜗杆轴与齿轮的接合是自锁的。
