Abstract: An elevator system, elevator retrofit kit, and detachable counterweight for providing a self-generating elevator emergency power source. The system converts kinetic energy of an elevator cab descending due to gravity into electrical energy used to regulate the speed of descent. The elevator system can be structured in numerous ways and includes either a generator or a motor in generator mode, driven by a cable attached to the elevator cab and activated by the descent of the cab. The elevator cab descends due to gravity, either by using a counterweight being sufficiently light relative to the cab to cause the cab to descend, or by using a counterweight system whereby power loss or interruption causes the unlocking of a detachable counterweight from a permanent counterweight.

Abstract: A flower pot arrangement, comprising a base and a flower pot. The base includes at least one side wall and a bottom surface engaging the at least one side wall and forming a holding region therewith. The bottom surface includes a plurality of ribs and a plurality of projections protruding into the holding region. The flower pot includes a lower surface and a side wall. The lower surface have a plurality of channels and a plurality of depressions. When the flower pot is in a first position, the plurality of ribs on the bottom surface of the base mate with the plurality of channels on the flower pot and the plurality of projections on the bottom surface of the base mate with the depressions on the flower pot. When the flower pot is in a second position, the plurality of projections on the bottom surface of the base mate with the depressions on the flower pot while the plurality of ribs on the bottom surface of the base do not mate with the plurality of channels on the flower pot.
