Abstract: A combination lever for a carburetor is an integrated shutoff lever and fuel valve. The combination lever includes a longitudinal portion for a handle and a cylindrical portion including a fuel path for the fuel valve. A carburetor casing is shaped to form a valve chamber and a carburetor chamber. The valve chamber supports the cylindrical portion. A directional cavity formed in the cylindrical portion of the combination lever regulates a flow of fuel to the carburetor chamber according to a rotation of the combination lever. At one position the directional cavity opens the fuel path so that fuel flows into the carburetor chamber. At another position the directional cavity closes the fuel path so that the flow of fuel is blocked. The combination lever may also include an abutment portion to engage a switch for completing an electrical shutoff path to an engine coupled to the carburetor.

Abstract: A thermal energy system includes a solar energy collector, a ground loop having an inlet and an outlet, and a heat pump. A first fluid conduit extends from the outlet to the solar energy collector, and from the solar energy collector to the inlet, for transporting a heat exchange fluid, from the outlet to the inlet through the solar energy collector. A second fluid conduit extends from the outlet to the heat pump, and from the heat pump to the inlet, for transporting the heat exchange fluid, from the outlet to the inlet through the heat pump. A fluid pump is provide for urging the fluid to flow from the inlet to the outlet through the ground loop, and from the outlet to the inlet through at least one of the first and second conduits. Control valves and a controller may be provided to automatically select a fluid flow mode from a number of selectable modes.

Abstract: An air diffuser system contains a manifold and a plurality of elastomeric "duckbilled" check valves. The manifold is constructed from a conduit material and can be arranged in many different configurations. The valves are made from an elastomeric material, such as rubber, preventing the valves from being clogged with sludge, sediment, or other debris commonly found in waste treatment water. Additionally, the valves can be bored with predetermined orifice sizes, allowing the volume and pressure of escaping air to be determined prior to installation. To make installation of the valves easier, various types of coupling devices may be used to attach the valves to the manifold. Examples of coupling devices include restrictive orifices, "Y"-shaped conduits, and nipple conduits. Multiple valves can also be fabricated on a common cuff prior to installation.

Abstract: A combined telephone AED simply integrates the function of a telephone and an alphanumeric entry device required for alphanumeric paging into a single unit by making use of the handset cradle switch to reset the unit from page mode to telephone mode whenever the handset is lifted. Paging operation is simplified through pre-stored entries in a directory giving both voice and paging numbers with the appropriate number being identified by the previously selected mode of the operation of the unit. Special purpose paging and speed dial buttons serve the combined function of identifying a mode of operation and initiating a search of the directory to reduce the number of keystrokes required of a user during typical operation.
