Abstract: Exemplary surface debris removal systems and methods are operable to remove debris from a signal transmitting/receiving surface. An embodiment provides power to, and then removes power from, a conductive memory wire that is secured to a moveable portion of a two-position snap spring. In response to providing the power to the conductive memory wire, a length of the conductive memory wire decreases so that the moveable portion of the two-position snap spring is pulled from an extended position to a retracted position. When power is removed from the conductive memory wire, the moveable portion of the two-position snap spring moves from the retracted position to the extended position. In response to the moving of the moveable portion of the two-position snap spring from the retracted position to the extended position, an energy is generated and transferred to the surface that dislodges the debris from the surface.

Abstract: A dual striker mechanism for a carpet-tapping machine comprises two striker grills which are mounted in a common body opposite one another so as to be pivotable about the longitudinal axis of their retaining rail. The tapping rods of the first striker grill thereby protrude into the gaps between the tapping rods of the second striker grill. The arrangement of the tapping rods of the two striker grills thereby forms a common horizontal plane. The striker grills are coupled to one another such that upon a clockwise pivoting motion of the first striker grill, the opposite one moves counter-clockwise. The drive motor for the striker grills generates an alternating pivoting motion about the longitudinal axis of the striker grills via an eccentric drive. The tapping rods of the two striker grills thereby move toward each other in their common substantially horizontal position.

Abstract: A chalkboard eraser cleaner including a completely closeable, box-like housing containing an electrically driven, rotatable beater. At the top of the container is a side, slot-like opening with a door for the insertion of the eraser to be cleaned. Right below the area in which the eraser is inserted, there is an eraser support surface of somewhat slack, mesh netting material supported between the walls of the container for supporting the eraser during beating, with the mesh netting located directly above the rotatable beater whose arms impact the bottom of the eraser through the mesh netting to clean the eraser. Below the beater and the mesh is a removable drawer located at the bottom of the container which can be removed for the disposal of the eraser dust, which generally will fall into the drawer during use of the cleaner. An electrical contact switch is positioned in the container adjacent to the forward end of the area in which the eraser to be cleaned is inserted.

Abstract: Coatings are loosened for removal from various substrates by rotating a chain-like flail against the coating while maintaining the flail oriented and positioned with respect to the surface of the coating so that the next-to-last terminal link of the flail barely strikes the coating on the edge of the link, twists and then whips the terminal link flat against the coating on the side of the link. The flail is useful for remote controlled operations as underwater or in a hazardous area as high radiation environment and may be employed for cleaning any underwater surface such as conduits, ships hulls, docks, and offshore drilling or production structures. In particular, the flail works well on underwater conduits when used in combination with a wire wheel brush which removes the coating from the conduit after the coating is first loosened by the flail.
