Abstract: A negative-pressure dust collector system employs a dust separator device to separate the dust that is entrained in a stream of dust-laden air, exhausts the air stream to a vacuum-inducing machine, and discharge the separated dust downward into a bagger arrangement. The latter employs an open-bottom generally rigid hopper with a grid across its open bottom. A flexible dust collection bag is clamped onto an exterior of the hopper and hangs from the hopper. Under vacuum, the bag closes off the open bottom of said hopper. The grid has openings dimensioned so that dust in the container passes freely through the grid when the vacuum-inducing machine is shut off, but so that the bag may be sucked up against the grid, but not sucked into the open-bottom hopper when vacuum is applied. A flexible apron may be attached to the bottom of the hopper between the grid and the dust-collection bag.

Abstract: The action of braking generates massive amounts of heat. It is known to install brake ducts 9, which channel air from the front of the vehicle to the brake discs 17. The air introduced by the brake ducts 9 is at an ambient temperature, much cooler than the brakes, and the airflow is closer to laminar (rather than turbulent) and continuously moves the hotter air away. This allows the brakes to shed heat at a faster rate and dramatically lowers the average operating temperature. The present invention provides a vortex tube 3 for supplying a stream of air 5 at a temperature substantially different from ambient temperature into brake ducts 9 to improve efficiency of the brake ducts 9.
