Abstract: A solar water-heating apparatus comprises an outer container sized and configured to receive a smaller inner container. The inner container includes an opening formed in an upright wall and an opening formed in a floor. A gap is located between the two containers. Once the device has been filled with a liquid, the liquid present within the gap may be heated by solar energy. The device may include a valve to prevent unintended flow of the liquid.

Abstract: A solar water-heating apparatus comprises an outer container sized and configured to receive a smaller inner container. The inner container includes a pair of openings, one formed in the floor thereof and one formed in the side wall thereof. The side wall and floor of the inner container define a reservoir capable of receiving a liquid. A gap is located between the floors and side walls of the two containers. Once the device has been filled with a liquid, the liquid present within the gap may be heated by solar energy, thereby increasing the temperature thereof. The liquid with the increased temperature becomes less dense and rises relative to the cooler liquid and travels upwards in the gap until the warmer liquid reaches an opening within the side wall of the inner container. The liquid then travels through the opening and back into the reservoir.

Abstract: An anode basket according to the present invention for use in electroplating operations includes a container for suspending anode metal in plating solution. The container has mesh walls formed of conductive, corrosion resistant material and is connected to an electrical power source by a wire attached to the container at a location below the surface of the plating solution.

Abstract: An anode basket for use in electroplating operations. The anode basket is formed of a pliant, shape-returning material which acts as a spring to ensure contact between the plating metal and the anode. The basket may be formed of a non-conductive plastic and the anode from corrosion-resistant conductive metal.
