Abstract: An anti-cinch automatic locking retractor. A web spool is rotatably mounted between a pair of upstanding walls. The spool includes a pair of flanges each having a plurality of locking teeth with the teeth spaced apart by an included angle. A pawl is pivotally mounted to the walls and is lockingly engagable with the teeth. A cam plate mounted adjacent the spool and rotatable therewith includes a cam surface extending through an angle greater than the teeth included angle to limit cinching of the web spool as the spool rotates to and from the locking position and through the included angle. A cam release rotatably mounted to the upstanding walls limits movement of the cam plate.

Abstract: A tool for adjusting threaded valve boxes that grips the valve box from the inside. The present tool allows valve boxes to be rotated without having to excavate in the vicinity of the valve box, and thus allows valve boxes to be quickly and easily adjusted prior to or after paving. The tool is easily adaptable to a power-take-off unit, and automatically engages the valve box upon rotation of the shaft.

An additional slack reducing mechanism is mounted to the seat frame opposite from the side of the retractor and includes a pivot member for automatically aligning the attached locking device when not in use.

Abstract: A squeeze film damper for the high temperature environments includes a fixed journal on a support, a floating journal on a rotating shaft, a damping ring in an annular chamber between the fixed and floating journals, and a pair of metal bellows straddling annular exposed channels defined at a pair of clearance gaps between the fixed and floating journals. The metal bellows are welded to the fixed and floating journals on opposite sides of the exposed channels and filled with high temperature resistant viscous fluid. The damping fluid flows to the damping chamber through the annular channels and the clearance gap between the fixed and floating journals.

Abstract: A method of imaging the heart to provide a distinct image using positron emission tomography comprises administering copper-64 citrate and a compatible carrier.
