Abstract: A cooling delivery system for a vehicle including a plurality of baffles mounted to the vehicle's engine compartment hood. A hood having a plurality of screens is pivotally mounted on the hood to cover the baffles in a down position. An air intake duct has a portion extending through the hood beneath the cover for receiving and conducting ambient air to a blower fan whereafter the ambient air is forced by the blower fan to traverse the vehicle's radiator.

Abstract: The discharge apparatus is used in conjunction with a fire suppression system and includes a plurality of gas cartridges communicating with one or more fire extinguishing tanks. The discharge apparatus includes a first cylinder-piston device which upon activation punctures a diaphragm of a gas cartridge. Gas released from the first gas cartridge pressurizes a related fire extinguishing tanks to cause extinguishing chemicals to be discharged. A small portion of the gas released from the first gas cartridge is responsible for the activation of a second cylinder-piston device associated with a second gas cartridge to cause the release of gas. The gas released from the second gas cartridge pressurizes a related fire extinguishing tank to cause extinguishing chemical to be discharged.

Abstract: A wheel for industrial use is constructed of five parts welded together to form a unitary piece. Specifically, the wheel includes a rim defined by a central cylindrical part having flanges welded to its opposite ends and cooperating therewith to define a single deep well. A pair of disks cooperate together to form a drive disk structure of the wheel. These disks are located within the central cylindrical part of the wheel and have convoluted peripheries welded to the cylindrical part. The periphery of one of the disks is located such that it crisscrosses the weld seam between one of the flanges and one end of the cylindrical part and is also welded to the last mentioned flange.
