  • Patent number: 11851833
    Abstract: A barrier is formed from one or more intermediate posts situated between a pair of end posts. Long flexible cables interconnect the end posts and extend adjacent each intermediate post. Each cable is wrapped one or more times around each post. End posts may include dual columns that permit cable windings around both columns. A spike embedded within the end of each cable enhances the purchase that can be gained by a clamp that presses the cable against the end post. The clamp has contact elements with converging side walls that grip the cable near the spike. To maintain the spike in place, a wire rope clip grips the cable over a constriction in its contained spike. Each cable is enclosed by a cable cover extending between adjacent posts. The cable cover is suspended at each post by a pair of tiltable hangers.

  • Patent number: 10604962
    Abstract: A barrier framework is formed from vertical posts and horizontal rails. Infill sections cover major openings in the barrier framework. Elongate junction elements overlay each rail and join adjacent infill sections. Edges of the infill sections fit within channels formed in the junction elements. Each junction element has an H-shaped cross-sectional profile, with the arms on one side shorter than those on the other. A cover element encloses the shorter arms of each junction element and clamps infill material against the longer arms.

  • Patent number: 4756210
    Abstract: A hydrokinetic, multiple ratio torque converter transmission having planetary gear ratio elements that establish a hydrokinetic torque path in low ratio and reverse gear and a bypass torque path in intermediate gear and third gear including a torque converter and an overrunning coupling wherein the intermediate gear and third gear is characterized by a mechanical torque flow or a viscous shear torque flow path, the third gear being a partial hydrokinetic regenerative torque flow path.

  • Patent number: 4203288
    Abstract: A hydrokinetic torque converter transmission for multiplying torque delivered from a driving member to a driven member comprising a bladed impeller connected to the driving member, a bladed turbine connected to the driven member and a stator located between the flow exit section of the turbine and the flow entrance section of the impeller, said impeller comprising a main impeller blade section and an auxiliary impeller blade section, the latter being located radially outward with respect to the former, and a centrifugally operated clutch structure for connecting together for rotation in unison the auxiliary impeller blade section and the main impeller blade section at high impeller speeds and for disengaging them when the impeller speed is less than a predetermined value.

  • Patent number: 4194604
    Abstract: A hydrodynamic torque converter mechanism having a bladed impeller, a bladed turbine and a bladed stator arranged in a toroidal fluid flow circuit enclosed within a common impeller housing, a friction clutch in the housing including a clutch disc with a friction surface thereon situated adjacent a cooperating friction surface formed on the housing, a stator sleeve shaft supporting the stator, an impeller sleeve hub journalled on the housing, a turbine shaft connected to the turbine and extending through the stator sleeve shaft, and a double circuit flow path for fluid circulating through the torus circuit, one circuit being defined in part by the annular space between the impeller hub and the stator sleeve shaft and the other circuit being defined by the annular space between said turbine shaft and said stator sleeve shaft and by the annular flow space between said friction surfaces.
