Abstract:

An apparatus () for cutting a corner of a stack () of sheet material, such as paper or plastic cards, to have a non-square shape. Broadly, the apparatus () includes a tray () for receiving the stack () such that the corner of the stack () projects through a gap () in the tray () into a cutting path, a blade assembly () which is slidable along the cutting path to cut the corner of the stack (), a drive assembly () for driving the blade assembly () along the cutting path, a clamping assembly () for exerting a clamping force on the stack (), and one or more spacer blocks () that fit closely within the tray () and do not project into the cutting path, including a spacer block () which is interposed between the clamping assembly () and the stack ().

Abstract:

A railroad friction-modification system for applying a friction modifier to a section of railroad track, the system comprising an external storage tank for storing the friction modifier, a railroad friction-modification assembly for applying the friction modifier, a tube for connecting the external storage tank to the railroad friction-modification assembly, and a mounting assembly for securing the railroad friction-modification assembly to the rail. The railroad friction-modification assembly includes an expandable membrane for storing the friction modifier, an inlet valve for receiving the friction modifier from the external storage tank, a housing for securely containing the expandable membrane, at least one outlet valve for expelling the friction modifier from the expandable membrane upon the application of a force, and a nozzle for directing the expelled friction modifier onto the section of railroad track. The force is applied by the wheel of a railroad car, such that the railroad friction-modification assembly pumps the friction modifier in a peristaltic action.
