Abstract: A horizontal directional drilling system. The system has a pilot drill and an exit side drill, with a drill string extending between them. A backreamer is positioned between the drills to enlarge a borehole. The pilot drill pulls and rotates the backreamer. The exit side drill adds segments to the product pipe and pushes the product pipe into the enlarged borehole. The exit side drill is equipped with a rotational disconnect. The disconnect is engaged to allow torque transfer between a motor and a spindle when adding segments to the product pipe. The disconnect is disengaged to prevent torque transfer between the motor and the spindle when pushing the product pipe into the enlarged borehole.

Abstract: Gutter systems, including a gutter protector and/or a gutter protector support. The gutter protector may help to reduce or eliminate the introduction and/or accumulation of leaves, tree needles, and/or other debris in the gutter system.

Abstract: An improved gutter screen which includes a first screen having mesh openings, top and bottom surfaces, and first and second opposing edges. A second screen having top and bottom surfaces is positioned adjacent the first screen so that a top surface of a second screen faces the bottom surface of the first screen. The second screen also has mesh openings, and first and second opposing edges, with the first opposing edge of the second screen being fastened to the first opposing edge of the first screen to form a first edge portion and the second opposing edge of the second screen being fastened to the second opposing edge of the first screen to form a second edge portion. The first and second screens are elastically deformable to permit a user to apply hand pressure to the gutter screen and compress the first and second edge portions toward one another from an uncompressed state in order to provide a force which holds the gutter screen in place over a gutter.
