Abstract: The package locking system comprises a box, a bag, a cable, and a lock. The box may comprise four side walls, a bottom, and a hinged lid and may mount to a building. Mail may be left inside the box for delivery. The bag, the cable, and the lock may be located inside of the box and may be used to accept delivery of one or more packages. The cable may pass through a casing around a package aperture on the bag. The ends of the cable may pass through the lock and may be coupled to the box. A package may be placed into the bag and the lock may be slid towards the bag to gather the material of the bag around the package aperture. An internal mechanism of the lock may prevent the lock from sliding away from the bag unless released by a key.

Abstract: A spray boom apparatus for attachment to a chemical and fertilizer-spreading farm vehicle for spraying chemicals over crops and farmland. The apparatus comprises a pair of spray booms which are hinged to a support rack. Each boom is further connected to the support rack by means of a hydraulic cylinder which allows each boom to be positioned in an outwardly-projecting dispensing position. The support rack is hinged to a stationary brace which is attached to the rear of the farm vehicle. A further hydraulic cylinder is connected between the support rack and the stationary brace. This further cylinder allows each boom to be tilted simultaneously to a closed position above the side windows of the cab of the vehicle when the booms are not in use.
