A specimen removal apparatus includes a pouch assembly fabricated from a flexible membrane, a pouch support, a drawstring having a knot and forming a noose disposed circumferentially around a mouth of the pouch assembly, an endoscopic tubular portion, and a drive rod. The pouch support includes a rocker arm assembly attached to a distal end of the drive rod. Proximal pulling of the drawstring closes the noose, thereby closing the mouth of the pouch assembly. The pouch assembly is detachable from the apparatus.

A clear water control device of a high energy mixer, and a high energy mixer. The clear water control device comprises a mounting base (1), a straight line actuator (3), a hinge shaft (4), a rocker arm (8), a lead screw (5), a threaded shaft (6) and a valve rod (9). The mounting base (1) is hinge-connected with a fixing seat (12) of the straight line actuator (3). The hinge shaft (4) is inserted in a middle shaft hole of the mounting base (1). One end of the lead screw (5) is fixed on the hinge shaft (4). The threaded shaft (6) sleeves the middle part of the lead screw (5). The threaded shaft (6) is inserted in a middle hole of the rocker arm (8). The upper end of the rocker arm (8) is hinge-connected with the valve rod (9). The lower end of the rocker arm (8) is hinge-connected with a push rod (11) of the straight line actuator (3). A through hole is arranged at the junction of the threaded shaft (6) and the lead screw (5). A pin (10) is arranged in the through hole. The automatic precision control of the amount of feed of the valve rod (9) is achieved, so that the slurry mixing effect of the high energy mixer is better than that in the prior art.

A bicycle frame assembly having a number of rotatable members configured to absorb shocks and impacts associated with operation of the bicycle. The assembly includes a frame constructed to support a rider and a chain stay having a rearward end that extends toward a wheel hub and a forward end that is pivotably connected to the frame. An absorber is pivotably connected to the forward end of the chain stay and extends to a rocker arm that is pivotably connected to the frame. A seat stay is pivotably connected to a rearward end of the rocker arm and extends to the rearward end of the chain stay. The rearward ends of the seat stay and the chain stay are pivotably connected to rotate about a common axis.

A selectable one-way rocker clutch assembly includes an inner race disposed radially within an outer race, first and second plurality of rockers, a selector ring and an apply plate. The inner race defines a plurality of pockets configured to operatively retain the first and second plurality of rockers. The first plurality of rockers is configured to resist rotation of the outer race relative to the inner race in a first direction. The second plurality of rockers is configured to resist rotation of the outer race relative to the inner race in a second direction. The selector ring is disposed radially between the inner race and outer race. The apply plate is configured to engage with the selector ring and, in so doing, rotate the selector ring to thereby selectively retract the first and / or second plurality of rockers and thus control the state of the rocker clutch assembly.

An endless track assembly that mounts to a wheeled vehicle. The assembly provides 1) a track suspension having fixed or adjustable, independently biased sets of idler wheels to vary the track contour without affecting track tension, 2) an eccentric bearing housing at a drive sprocket controls track tension, 3) a contoured peripheral edge at the drive sprocket prevents ice and mud buildup, 4) rubber-coated, plastic idler wheels facilitate track movement, 5) a multi-vehicle compatible adapter mounting plate accommodates a variety of vehicles, 6) a rotation limited torsion coupler and / or rotation limiting coupler arms prevent track contact with the vehicle, 7) a locking steering arm coupler prevents loss of steering control, 8) shaped track lugs and channels clear and direct debris away from the track suspension and drive assembly, and 9) a center, spring biased coupling suspension stabilizes and enhances the contour following and load handling capabilities in the center region of the track. The improved suspension particularly supports sets of idler wheels in pivotal relation to the track support frame and resiliently biases a pre-tensioned rocker arm that links adjacent suspension arms mounted to the adjoining idler wheels. Suspension arm movement induces expansion and contraction of tension springs coupled to the rocker arms to augments shape changes at the track contact surface to optimize traction and steering control.
