Abstract: A fabrication method of a holding sleeve is provided. The holding sleeve is adapted to dispose around a body portion of a main body and can rotate relative to the body portion. A blocking member is disposed in at least one through hole of a first sleeve. A second sleeve is movable relative to and disposed around the first sleeve. The blocking member is controllably pressed by the second sleeve to be partially received in an annular groove of the body portion. An elastic member is disposed around and between the first sleeve the first and second sleeves. Before the second sleeve is mounted to the first sleeve, a part of the elastic member corresponds to the blocking member in a radial direction of the first sleeve and can limit the blocking member to locate in the through hole.

Abstract: The invention discloses versions of a horizontal axis wind turbine and methodologies for the design of wind turbines, which are capable of extracting both kinetic and thermal energy from the wind. The wind turbines disclosed use a large diameter forward inlet fairing to accelerate the airflow to the more effective outer radii of the turbine rotor where the airflow is constrained by an airfoil-shaped flow control ring. This serves to prevent rotor tip losses, to inhibit wake expansion, and to accelerate the airflow through the turbine. A similarly large diameter aft pressure recovery fairing promotes rotation and contraction of the wake downstream of the turbine. Further methodologies for optimization and detail design are disclosed.

Abstract: The invention discloses improved versions of a horizontal axis wind turbine and new fundamental methodologies for the design of wind turbines, which are capable of extracting both kinetic and thermal energy from the wind. The wind turbines use a large diameter forward inlet fairing to accelerate the airflow to the more effective outer radii of the turbine rotor where the airflow is constrained by an airfoil-shaped flow control ring, which also serves to prevent rotor tip losses, to inhibit wake expansion, and to accelerate the airflow through the turbine. A similarly large diameter aft pressure recovery fairing promotes rotation and contraction of the wake downstream of the turbine.

Abstract: A pneumatic tire and a process to retread a tire is provided. The retreaded tire has a carcass and a crown region, wherein the crown region comprises a belt reinforcement structure located between the carcass and a tread. The retreaded tire further comprises a cementless cushion layer located radially outward of said belt reinforcement structure, and one or more reinforcement plies located radially outward of the cementless cushion layer. The one or more reinforcement plies is formed from a substantially continuous strip of reinforced elastomer which is wound from one side of the crown to the other side in a substantially continuous manner. The reinforcement ply may be formed from spirally winding the strip about the carcass, or one or more reinforcement plies may be formed from winding the strip about the carcass in a zigzag pattern.
