Abstract: Machine chuck jaws, and a related method of manufacture, are provided. The machine chuck jaws are formed from an additive manufacturing process and include one or more gripping pads per chuck jaw. An axial stop is also formed from an additive manufacturing process and provides a flat surface for workpiece placement. The gripping pads equally distribute the clamping pressure, and the additive manufacturing process provides unique shaping capabilities and a honeycomb internal cross-section, thereby achieving a lightweight design. The reduction in weight allows for a decrease in pneumatic pressure used to actuate the jaws, resulting in a corresponding reduction in the clamping pressure which helps improve the form of the workpiece being machined.

The shuttle is movable between a filling position, in which the dosing recess is in alignment with an opening of the container, and an inhalation position, in which the dosing recess is in alignment with the vortex chamber. The opening of the container is elongated along a major axis and the dosing recess is elongated along a main axis and, when the shuttle is in the filling position, an edge of the opening of the container encloses the dosing recess.

Abstract: Systems and methods for actuating automatic sliding doors on railroad hopper cars are disclosed. The system includes a cylinder having a first cap end mounted on a hopper car, and a second rod end having a clevis. The cylinder has a piston rod which extends, causing an actuating reinforcer coupled to the clevis to rotate around a coupled main shaft. The rotational motion of the actuating reinforcer causes an operating lever, also coupled to the main shaft, to rotate. A connecting link translates the rotational motion of the operating lever to a door pan fulcrum mounted to a sliding door, causing the door pan fulcrum to pull the sliding door open. The system also enables automatic locking in an analogous way, with the door pan fulcrum pushed to close the sliding door, when the cylinder piston rod returns to its original position.

Abstract: A ramp structure for a mobile platform includes at least one ramp member structured to be operably coupled to the mobile platform. The at least one ramp member is structured to be deflectable toward a ground surface so as to form a ramp responsive to contact with a subject vehicle wheel when the ramp member is operably coupled to the mobile platform and the mobile platform resides on the ground surface. The ramp extends in a direction from the ground surface toward a top surface of the mobile platform.

Abstract: Machine chuck jaws, and a related method of manufacture, are provided. The machine chuck jaws are formed from an additive manufacturing process and include one or more gripping pads per chuck jaw. An axial stop is also formed from an additive manufacturing process and provides a flat surface for workpiece placement. The gripping pads equally distribute the clamping pressure, and the additive manufacturing process provides unique shaping capabilities and a honeycomb internal cross-section, thereby achieving a lightweight design. The reduction in weight allows for a decrease in pneumatic pressure used to actuate the jaws, resulting in a corresponding reduction in the clamping pressure which helps improve the form of the workpiece being machined.
