Abstract: Apparatus for removing particulate from gases. The apparatus includes an inlet conduit, an outlet conduit, and a cylindrical gas processing chamber positioned between and interconnecting the inlet conduit and outlet conduit. The processing chamber is also connected to a particulate collection chamber by a channel. The gas processing chamber includes a cylindrical wall. A hollow cone-shaped deflector member is positioned in and spaced away from the walls of the processing chamber and is positioned between the inlet and outlet conduits. Gases entering the apparatus flow through the inlet conduit and contact the deflector member. The deflector member directs the major portion of gases from the inlet conduit radially outwardly toward the wall of the gas processing chamber. The gases deflected radially outwardly travel around the deflector member and along the wall of the processing chamber.

The cover includes an articulated support frame adapted to be assembled to enclose and define a chamber and to be disassembled for compact storage; a first sheet of pliable material having a pair of opposed side edges adapted for detachable connection to the walls of the bed of a truck to tension the first sheet in horizontal orientation over the floor of the truck bed; a second sheet of pliable material attached to the first sheet and having an outer edge adapted to be connected to one of the bed walls; and, a third sheet of pliable material attached to the first sheet and having an outer edge adapted to be connected to one of the bed walls.

Abstract: An improved disc brake system of the general type including a brake frame having a pair of spaced apart rails, a pair of brake linings slidably carried on the brake frame rails, a circular rotor rotatably carried on the wheel assembly of a vehicle and having smooth planar inboard and outboard contact faces, a caliper assembly slidably mounted on the rails of the brake frame, and, a brake pedal operatively associated with the caliper assembly, the caliper assembly having a piston which when actuated by depressing the brake pedal first forces one brake lining against the inboard contact face of the rotor and then causes the caliper assembly to slide along the brake frame rails to force the other brake lining against the outboard contact face of the rotor. The improved disc brake system minimizes the amount of heat generated when the brake linings frictionally contact the rotor and markedly increases the operational life of the rotor and brake linings.

Abstract: Improved apparatus for routing a groove in the surface of a panel of material. The apparatus includes a base, a first elongate horizontally oriented support arm having one end pivotally attached to the base and having another end pivotally attached to one end of a second elongate horizontally oriented support arm. A milling head is mounted on the other end of the second elongate support arm. The pivotally interconnected support arm pair permit the milling head to be laterally displaced in an infinite number of directions. The application of an upward or downward force on the milling head causes resilient flexure of the support arm pair, the flexure permitting the upward or downward displacement of the milling head and of a tool bit rotatably carried in the milling head. The apparatus utilizes the resilient flexure of the horizontally disposed support arm pair to insure that a groove of constant depth is routed in the surface of a panel of material.
