Abstract: A turkey call system includes a pot, a sound board and a striking surface which is held together with magnets. A striker contacts the pot to produce a sound that is capable of attracting turkeys.

Abstract: A water distribution apparatus comprises a water user outlet facility and a water recirculation loop. The water re-circulation loop comprises a water supply, a water pump for establishing and maintaining a flow of water in the loop, a water delivery path extending from the pump to a water user outlet facility, a water return path extending from the water user outlet facility to the water supply, and a thermal disinfection apparatus disposed in the water delivery path for improving the potability of the water within the loop. A thermal heating apparatus and control is provided in the water delivery path or water storage tank to add thermal energy to prevent freezing of the stored water as well as the water flowing in the water re-circulation loop.

Abstract: Water is supplied to a water user outlet facility by maintaining a tappable flow of water in a recirculating loop that includes a pump such as a centrifugal pump driven by a substantially constant speed motor to establish the flow, a water delivery path that extends from the pump to the outlet facility, and a water return path that extends from the outlet facility back to the pump. The flow is permitted to be controllably tapped at the facility by a water user while directing any untapped portion of the flow into the water return path. Such recirculation avoids stagnation and thereby impedes deterioration in the potability of the water. Further such recirculation makes the recirculating loop and water within the loop less sensitive to the temperature of the surrounding environment. The recirculating loop may include a water purifier such as an ultra-violet lamp source to kill organic contaminants and, as well, may include a filter to remove inorganic material.

Abstract: A changeable copy sign assembly comprising a plurality of wafers each bearing a single indicium on a relatively opaque background. The wafers and a backing strip are removeably retained to a face plate of the assembly at an elongated, window-like opening, and the backing strip comprises opaque makings for preventing the leakage of light between adjacent wafers.
