Abstract: The invention is an improved rotary steerable tool. The improved rotary steerable tool comprises a control tube that slides vertical within a mandrel in response to changes in drilling fluid pressure, thereby opening and closing a channel between the mandrel and a piston chamber in a rotationally isolated sleeve. With the channel open, a piston in the piston chamber is exposed to the drilling fluid. When the drilling pressure is sufficient to cause the piston to move, the piston forces a deflection pad outward. After the deflection pad engages a borehole wall, any additional increases in pressure force the opposing side of sleeve toward the opposite wall, thereby tilting the direction of any attached drill bit. An optional guide lug and alignment sleeve orient the deflection pad with respect to other components.

Abstract: A receptacle (200) for waste, the receptacle (200) including an elongated body member (202) having a first end for locating on or in the ground and a second end with an opening (201) therein for receipt of waste, the body member (202) further including inlet means (212) to permit atmospheric air to be drawn into the body member (202) on the application of a vacuum to the body member (202), wherein contents of the receptacle (200) are capable of being drawn from the receptacle (200) on the application of a vacuum to the body member (202) by entraining with atmospheric air drawn into the body member (202) by the vacuum.

Abstract: A siding installation tool for support pieces of siding and act as a guide to facilitate consistent alignment of the siding being installed includes a clamp assembly coupled to an extendable guide assembly. The clamp assembly is lockable to a piece of siding and the guide assembly is adjustably extendable from the clamp assembly to support a second piece of siding for installation.
