Abstract: An electronic pneumatic brake system for trains which significantly improves brake cylinder pressure build-up time and facilitates essentially instantaneous and simultaneous braking on all cars of the train. The electronic pneumatic brake system includes electronic pneumatic control valves on the cars which individually control the braking on each car or a pack of cars and which are regulated by an electronic pneumatic controller on each car that receives electronic braking and release signals by way of wireless communication from an electronic head end unit on the lead locomotive, or where no head end unit is provided in the locomotive, receives pneumatic braking signals through the brake pipe.

Abstract: A pallet system including two embodiments of a pallet having a deck including four sides and providing a load-supporting surface. A plurality of spaced hollow legs project from the opposite side of the deck and a plurality of hollow reinforcing ribs project from the opposite surface to define channels in the load-supporting surface. A hollow ridge projects from the opposite surface and extends along the sides at the periphery of the deck to define a groove in the load-supporting surface for receiving the bottom edge of a wall. There is at least one transverse rib projecting from the opposite surface and extending between opposite sides of the deck to define a transverse groove in the load-supporting surface for receiving the bottom edge of a transverse wall whereby walls may extend upwardly from the deck to divide and separate the load-supporting surface into discrete areas.

Abstract: An industrial load-carrying pallet comprising an integral sheet of material formed with strengthening ribs extending thereacross, three centrally disposed pedestals extending downwardly at the center line and generally W-shaped pedestals disposed adjacent the side extremities. Grooves extend downwardly from the upper surface and are disposed along the circumference of four circles for receiving the bottom rims of four drums. The pedestals have recesses therein disposed on the circumference of four circles whereby the pedestals may rest upon and engage the top rims of four drums. The area of the top surface within each circle for receiving the bottom rim of a drum is spherically concave. The side pedestals have spaced converging walls in a downward direction which are joined at the lower extremities by a bottom base. Empty pallets may be stacked by placing the pedestals within one another.
