  • Lawn mower rope guide
    Patent number: 11206761
    Abstract: A starter system for a lawn mower includes a handle tube and a rope guide. The rope guide includes a rod member with three bends defining four rod segments. A first rod segment extends linearly through opposite openings in the tube, a second rod segment is curved at a diameter approximating a tube surface diameter, a third rod segment extends longitudinally along the tube, and a fourth segment extends to a distal coil. Two points of direct contact between the rod member and the tube outer surface include a first contact point on the second rod segment adjacent a tube opening indentation and a second contact point on the third rod segment near the third bend. The rod segments are configured such that tightening of a nut member dynamically deflects the second and third rod segments to increase a gap with the tube outer surface.

  • Pavement repair method and system thereof
    Patent number: 11124926
    Abstract: A method for repairing/treating a pavement with the use of a rheologically modifier is disclosed. The method comprises first applying a layer of a rheologically modifier composition comprising a rejuvenating component onto the top surface of the pavement that needs repair, then applying a second layer of an asphaltic binder onto the rheologically modifier layer. The second layer of asphaltic binder effectively seals the rheologically modifier layer with the rejuvenating component for intimate contact with the top pavement surface, thus penetrating the surface layer to extend the life of the pavement surface, arresting the deterioration of visco-elastic properties and restoring some of those properties.
