4686866 COMPACT ROBOT WRIST ACUATOR Mark E Rosheim A present invention is a robot wrist actuator including a mechanical joint having a housing. First and second glmbal assemblies are rotatably mounted to the interior of the housing to provide pitch and yaw movement. A collar is rotatably attached to the housing. A drive mechanism is connected to the second gimbal assembly to provide roll movement. An output shaft for tool attachment is connected to the first gimbal assembly. A drive assembly preferably including linearly-actuated rods provides motive force for movement of the first and second gimbal assemblies.
4687097 WAFER PROCESSING CASSETTE
quids during automated processing, and vertical support bars are provided for strengthening of positioning members of the cassette. The rear end includes a downward arch. The processing wafer cassette provides for £37 on-center+38 + 0 processing where the carrier center of gravity is on-center of the axis of centrifugal wafer processing machinery. Each of the dividers in cross section are geometrically configured for passage of chemicals during processing. + RE

Roger L Mortensen assigned to Empak Inc Wafer cassette for processing of silicon wafers which includes a plurality o f open supported reinforced wafer dividers for supporting a plurality of wafers in alignment in opposing dividers of the cassette and for automated robotic processing of the wafers while in the cassette. The wafer cassette utilizes an H-bar end with a configured rod reinforced open H-front which is fully functional and strategically located. The dividers are supported by one or two pairs of longitudinal horizontal supports secured to the ends providing for an open area between each of the dividers for passage of li-
An automated fuel rod production system includes a radioactive powder fabrication and processing stage, a pellet fabrication stage, a pellet processing stage, a tube preparation stage and a fuel rod fabrication and inspection stage, all of which provide a continuous (paced) mode of operation from the conversion of a radioactive gas to powder, through the fabrication of the powder into pellets, to completion of the assembly of the fuel rods. Extra capacity is designed into the system at critical points in the powder processing and pellet fabrication and processing stages to facilitate the continuous, paced mode of operation.
