Abstract: A ceiling fan cover that can be easily placed onto and removed from a ceiling fan to provide the fan from dust, wind, water, moisture, paint and other potentially harmful element. The cover can be constructed of a flexible or non-flexible material that contains opening and closing means that permit the cover to be placed onto and closed around said fan and then opened to remove the cover from the fan. The cover preferably is made of a material to permit its reuse.

Abstract: A temperature compensation valve is hereby provided wherein the inner cavity of the valve comprises a puck, a metal piston (gas control device), and a spring. The spring serves to bias the piston towards the puck, and the puck expands and contracts proportionately in response to increases and decreases in temperature of the upstream gas. Furthermore, the piston will move accordingly, wherein an increase in temperature causes the expansion of the puck directing the piston in such a way to obstruct the orifice that allows the gas to pass through the valve, thereby controlling the gas flow to compensate for the pressure variations.
