  • Patent number: 6168433
    Abstract: A dental prophy angle adapted to be engaged with a dental handpiece having a nose cone and a low-speed rotary driver within the nose cone. The prophy angle has a proximal end adapted to releasably engage with said nose cone, and a distal end having an implement-mounting member rotatable therein. A flexible shaft extends from the nose cone through the angle to the mounting member and has a diameter which is substantially smaller than the interior wall of the prophy angle. The shaft has a coupling member with a free axial end adapted to engage the rotary driver in the nose cone to be rotated upon rotation of said driver, and an opposite captive end connected to said shaft with a shoulder surrounding said flexible shaft and facing away from said free end to confront an abutment limiting axial displacement of said coupling member within the prophy angle.

  • Patent number: 4542805
    Abstract: An automatically retractable pivotal step assembly is used on scaffolding and storage structures, particularly in a warehouse environment. The automatic retractability feature is particularly important in keeping the step assembly from being struck and broken off by loading equipment, or causing injury to workers or damage to material being transported by loading equipment.The step assembly is pivotally secured to a stanchion member of the storage rack structure at a selected height to permit a warehouse worker to ascend to a second or higher level of the storage structure and then be automatically returned and stored in a retracted position behind the stanchion member when not being used. Several step assemblies may be vertically aligned on the stanchion in combination at increasing heights to permit access to multiple levels of the structure.
