Abstract: The present specification provides a device and method for controlling a winch parcel delivery system through an uncrewed aerial vehicle (UAV) or drone. The example apparatus contemplates the use of a winch that will attach to a hook with active and passive release mechanisms through a winch line. The apparatus is enabled to attach to a parachute recovery system. The apparatus can detect when the ground has been reached to enable safe delivery of parcels. The apparatus can removably attach to various types of drones.

Abstract: Apparatus for adjusting backlash out of a positioning assembly for shaft mounted ring useful in multiple rip saw machinery and for minimizing arbor length. A pair of axially oriented straps secured to the ring and positioned along the shaft for axially positioning the ring on the shaft wherein a radial pin carried by the ring is eccentrically rotatable in a mating aperture in one of the straps to adjust backlash between the straps and the ring out of the assembly when the pin is rotated. The saw hubs and respective saw adjusting collars are arranged in a semi-interleaved nesting relationship resulting in reduced arbor length.
