Abstract: A piston velocity control and stability control system is provided for a combustion powered tool having a self contained combustion engine. The system includes a ring that may be adjusted relative to exit ports in a cylinder of the combustion engine. The ring includes openings which may be incrementally aligned between a completely exposed, and a substantially closed position relative to the exit ports. Displaced air volume within the cylinder exits through the exit ports as a piston advances down the cylinder, and the velocity of the piston will be greatest when the exit ports are completely exposed. User initiated reduction of the effective size of the exit ports by adjustment of the ring will reduce piston velocity as described per application. A nosepiece used to guide the driver blade and position the blade over a fastener is isolated from the cylinder so that the nosepiece remains stable relative to the workpiece upon combustion and until the driver blade strikes the fastener.

Abstract: A rotary atomizing applicator includes a shaping air system having first orifices discharging air against the outer surface of the bell cup, with the air following the bell cup and being released from the bell cup at the forward edge of the bell cup. A terminal portion of the outer surface of the bell cup directs the flow of air to shape the pattern of coating released from the bell cup. A second pattern of air is directed from outwardly and behind the bell cup inwardly toward the forward edge of the bell cup.

Abstract: A headlamp adjuster includes an output shaft driven by a co-rotatable gear. Threads on the shaft engage splines in a thin wall boss, the splines having limited circumferential engagement with the screw. The thin wall boss deflects outwardly in response to forces that build in the engagement of the shaft and splines, to release driving engagement between the splines and the shaft.

Abstract: A method and system for controlling ventilation in a welding helmet is provided. The invention may be adapted to a wide variety of system types, and may reduce or eliminate the need for a shroud or barrier around the head and neck of the welder, of the type used in PAPR systems. The airflow system includes forward and rearward air streams, directed onto the face of the welder, onto the top of the head of the welder, and toward the back of the head of the welder. The air streams help to cool the welder, provide a fresh source of air for breathing, and create a positive pressure system that reduces or excludes entrainment of contaminated external air into the forwardly directed air flow. Certain embodiments may include streams that are filtered, split or redirected via deflectors and conduits to achieve the aforementioned goals.
