    摘要: A bushing of the type used to limit wobble in drill pipe, the improvement comprising a bushing defined by two halves, each half having two ends adapted to buttingly engage corresponding ends of the other, and each further defining a receiver section along one of its ends; a flexible hinge piece matingly joined to the receiver sections with the opposite ends of the halves remaining free to move relative to one another, whereby the halves are rotatably affixed together at one end, but the opposite ends remain free to open. The bushing may be comprised of a first polymeric material, and the hinge piece comprised of a second, more flexible, polymeric material. Each half of the bushing may have mounted thereto a handle projecting upwardly.

    摘要: Many playsets include one or more tower sections with one or more platform sections supported above the ground or a similar support surface with a support structure or framing. In certain embodiments, a curved wall portion defines one or more panel openings. Subpanels may optionally be mounted into the openings. A balcony floor protrudes outwards with a curved outer edge or face with an interior flat floor edge adjoining an edge of a polygonal platform section floor to enlarge the square footage of the floor area of the platform section.

    摘要: An adaptive load limiting seat belt retractor particularly adapted for motor vehicle applications. The retractor provides multiple levels of load limiting through the use of a pair of internal torsion bar elements. The torsion bar elements control the tension force on the seat belt webbing during an impact in a manner which provides desirable crash management characteristics. The retractor can be switched between high and low load limiting modes through activation of a pyrotechnic pretensioner. When the pyrotechnic pretensioner is not activated, the retractor provides a low load level characteristic. Pretensioner activation switches the retractor into a high load level operating condition. A high load limiting level is provided when the pretensioner is not activated if the spindle rotation exceeds a limited level in the low load limiting condition. A degressive load limiting feature may be provided to cause load limiting to begin at a higher level than the high load limiting level, and then step down the high load limiting level.
