Abstract: A water pond potted plant support for supporting a potted plant in a body of water contained in an enclosure. The support has at least one horizontal circular pot receiving ring member configured to encircle a pot containing a potted plant and support it in an upright position adjacent to a surface of the enclosure at a selected depth beneath the top surface of the body of water. In one embodiment, the support has a horizontal circular base ring supported on a horizontal surface of the enclosure, a lower circular ring smaller in diameter than the diameter of the base ring, an intermediate circular ring, and an upper circular ring smaller in diameter than the intermediate circular ring connected in vertically spaced relation by a plurality of rod elements secured therebetween in circumferentially spaced relation and a bail pivotally connected to the upper ring.

Abstract: A method and apparatus for the measuring of the imbalance and the calculation of the location and size of the necessary weights to be added to a rotating object to balance it. Included are a mounting surface for receiving the object and a shaft affixed to and extending away therefrom with the shaft supported at two spaced apart points therealong, and a pair of pressure sensors with one each at the two support points of the shaft for providing a signal that is proportional to the force exerted by the shaft at the corresponding one of the support points as the object is rotated. In addition, a position and speed of rotation detection means is affixed to the shaft to continuously provide speed of rotation and position data of the shaft. Also there is a pair of tracking filters, each disposed to receive the output signal from a different one of the pair of pressure sensors with the center frequency of both filters being substantially the speed of rotation of the shaft.
