An operator controlled roof bolter with a flexible shaft drill and a roof bolt inserter for drilling and inserting a roof bolt into an unsupported roof of a mine while the operator is positioned at an outby station under a supported roof. The flexible shaft roof drill is constrained to a frame of the roof bolter for pivoting movement between a rest position and a working position. The roof bolt inserter is mounted on a slide for linear movement and limited rotational movement between a retracted position and an extended position for positioning a roof bolt held by the inserter into registration with a hole drilled by the roof drill.

Disposal container structure for the disposal of waste radioactive materials includes inner structure comprising a cover member with an inlet port and an annular seal surface portion, and depending filter structure attached to the cover structure that includes circumferential side wall structure and bottom wall structure that defines an enclosed chamber volume in which waste materials are introduced for storage therein through the inlet port. The container structure further includes outer structure that has circumferential side wall structure corresponding in shape to the filter structure of the inner structure, bottom wall structure that defines a chamber for receiving the filter structure of the inner component, and annular seal surface structure formed on the side wall structure for mating with seal surface structure of the inner structure to seal the storage chamber volume defined by the filter structure. Discharge passages across the seal surface provide flow paths for discharge of liquid from the region between the circumferential inner surface of the outer structure and the circumferential outer surface of the filter portion of the inner component. The container structure also includes drive surfaces for mating engagement with centrifuge structure for releasably engaging drive surfaces of a centrifuge system for subjecting the container structure to centrifugal forces in excess of about fifty Gs for separating water and similar liquids from solids retained within the chamber structure of the inner component.

The invention provides a manually operated or automated clamping means to seal a solid support substrate to a solid support cover creating a uniform environmental chamber above a specimen mounted to the support substrate. The clamping means may consist of several components that may act ad a system to provide a repeatable and uniform clamping load to the substrate and cover.

A torquer/thruster with a hydrostatically actuated chuck assembly configured to drivingly engage a flexible roofdrill for applying rotational torque and longitudinal thrust to the roofdrill shaft. The chuck assembly is mounted within a rotatable and longitudinally movable piston assembly, the chuck and piston assemblies fixed against relative movement with respect to one another. The piston assembly is mounted within a rotating barrel assembly, the piston and barrel assemblies being fixed against relative rotational movement and being constrained for limited longitudinal movement with respect to one another.

A self-advancing conical boring tool with a tapered frame for supporting roller cutters, each of which has a frusto-conical body with a plurality of teeth randomly disposed about its periphery. Each roller cutter is constrained within a pair of thrust bearings and a pair of self-aligning spherical roller bearings for free rotation about an axis that is both oblique and skewed relative to a longitudinal axis of the tool. A flexible diaphragm is captively held to the frame proximate each roller cutter and forms a pressure compensated chamber for a bearing lubricant, one face of the diaphragm being adjacent a thrust bearing and the other face of the diaphragm being exposed to the environment through a vent.

A robot arm assembly a base unit with a shoulder assembly rotatably disposed on the base unit. A lower robot arm is pivotably attached to the shoulder assembly. An upper robot arm is pivotably attached to the lower robot arm. The base unit includes a first motor which rotates a main shaft fixed to the shoulder assembly to rotate the shoulder. A second motor in the base unit rotates a second shaft in the shoulder assembly extending through the main shaft to pivot the lower robot arm with respect to the shoulder.

A firing pin assembly with a firing pin having a shaft with a distal bearing thereon. The firing pin has a standby position, a load position, and a fire position. A cam engages the bearing and is configured to drive the shaft between the standby position and the load position. A spring about the shaft is compressed when the shaft is driven into the load position. A driver turns the cam when energized to drive the shaft from the standby position to the load position and then to turn the cam further whereupon the compressed spring urges the firing pin to fire.

A mobile remotely controlled robot includes a robot platform and a robot arm maneuverable with respect to the robot platform. A housing is configured to be removably mounted to the robot arm. A sleeve is translatable with respect to the housing for receiving a weapon therein. There is a gear rack on the sleeve and a pinion gear, rotatably disposed in the housing, is engaged with the gear rack. A braking subsystem resists rotation of the pinion gear when the gear rack translates upon firing of the weapon.
