Abstract: A dewatering system for separating a slurry into solid material and effluent water. The dewatering system comprises a plurality of support frames arranged to enclose an interior space of the dewatering system, with the interior space being configured to receive the slurry. The dewatering system further includes geo-fabric material positioned on a portion of the support frames, with the geo-fabric material being configured to filter the slurry received within the interior space, such that effluent water permeates through the geo-fabric material and is discharged from the interior space. The dewatering system further comprises a dump door assembly associated with at least one of the support frames, with the dump door assembly including a plurality of hatches configured to selectively open to allow effluent water to be discharged from the interior space of the dewatering system.

Abstract: A linearly actuated switch assembly is adjustably disposed in a housing stem bore of a robotic crash protector device. An actuation plate is disposed over the central bore of the contact surface. As the piston moves toward the housing base in response to a crash force or torque applied to the actuator, the actuation plate moves in an axial direction, and contacts and actuates the switch. The actuation plate is biased towards the contact surface by an actuation spring disposed between the actuation plate and a spring plate that is rigidly affixed to the housing stem. This arrangement allows the actuation plate to “float” with respect to the fixed spring plate. In particular, the actuation plate may assume the orientation of the piston, which may be canted from its default orientation—normal to the device central axis—by uneven application of force by the actuator.

Abstract: A robotic crash protector device is configured for heavy payload applications. The device includes a housing, a piston and an actuator movably mounted within the housing, a cam member secured within the housing in fixed relation to the housing's base, and a switch. The cam member includes a cam surface with some portions being closer to the housing's base than other portions. The actuator includes bearing members that are configured to, responsive to a rotational force imparted to the actuator, move along the cam surface and thereby collectively displace the piston. The switch detects this displacement and indicates a crash. When moving along the cam surface, the bearing members are each configured to engage the surface along a line of contact, rather than at a single point. With forces imparted to each bearing member and the cam surface distributed across a line, the components better endure heavy payload applications.
