Abstract: A robotic gripper for transporting an object such as a disk-shaped integrated circuit wafer by contacting and gripping only its edge surface. The robotic gripper includes a plurality of elongated fingers which are joined together at a central location from which they project outward in the shape of the letter "X" to their fingertips. Each fingertip may be individually extended outward from or retracted inward to the edge surface of the object to be transported. To adapt the fingertips for grasping the edge of disk-shaped integrated circuit wafers, each fingertip is formed with a projecting lip having a V-shaped notch into which a wafer's edge surface is received while it is being gripped. Each finger includes a bellows through which a cable communicates force from a remote motor to the fingertip. A housing encloses cables and gears used to move the cable.

Abstract: A load-lifting mast especially adapted for an automatically-guided, driverless vehicle has automatic features for ensuring accuracy and reliability of operation despite the absence of a driver. For load-lowering purposes, a slack chain sensor senses whether or not the load-supporting carriage is supported by the mast, and the carriage is withdrawn from the load when no support by the mast is indicated. The slack chain sensor also cooperates with a carriage height control system by overriding it to cause lowering past a target height until the carriage is supported independently of the mast. A carriage height sensor self-calibration system continually recalibrates the height-sensor readings automatically while the mast is in use to compensate for height sensor slip, chain stretching, and other mechanical variables. The stack chain sensor cooperates with the self-calibration system to enable it to reference to the ground or other surface upon which the vehicle travels to compensate for such other variables as tire wear. The mast is preferably powered by an electric motor-driven screw member having a wear-preventing, universal-joint-type connection to the carriage-lifting mechanism to prevent the imposition of unsymmetrical loading on the screw member. The electric motor has field effect transistor controls operable over a wide range of source voltages.

Abstract: Systems and methods for treating hazardous materials are disclosed. One exemplary implementation provides a system for rendering chemical weapons materiel less hazardous. This system includes a detonation chamber, an expansion chamber, and an emission treater adapted to treat gas from detonation of the chemical weapons materiel. The emission treater yields a substantially dry residual waste stream and a treated gas suitable for venting to atmosphere. The emission treater may treat the gas with an alkaline powder that interacts with the gas, producing the residual waste stream.
