摘要： A conveyor belt tensioner that meets this object, as well as other objects which will become apparent upon reference to the following detailed description and accompanying drawings, is provided by a conveyor system in which a belt is trained about first and second end rollers that are suspended for rotation between opposed side frames. A motor is provided for moving the belt with respect to the side frames. A third roller that engages the belt is provided that is mounted between the side frames for incremental movement for tensioning the belt.

摘要： An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.

摘要： An optical scanning or positioning mechanism has a head on which optical components are mounted and an actuator coupled to the head to cause the head to move when the actuator is actuated. There are one or more sets of flexure bearings mounted in the mechanism. The flexure bearings have a restoring torque when moved from a rest position. The bearings are coupled to the head to allow the head to move when actuated by the actuator. One or more magnets are mounted in the mechanism in a location other than in the actuator to compensate for the flexure bearings restoring torque.
