Abstract: The present invention is a spotlight with adjustable focus that has a focus fixing mechanism to prevent inadvertent changes to the focus of the light, while still allowing user-friendly intentional adjustment of the focus. The mounting collar of the reflector assembly rotates on helical threads on the neck of the lamp assembly so that the focus of the light may be adjusted. The focus is fixed in position by a plurality of ridges and valleys on the lamp assembly that mate with corresponding ridges and valleys in the collar of the reflector assembly. The collar of the reflector assembly is sufficiently flexible or expandable so that the focus of the lamp may be intentionally changed by applying sufficient rotational force to the reflector assembly. The collar is sufficiently rigid that the reflector assembly will not rotate as a result of incidental vibrations or movement.

Abstract: An exhaust dispersion device for an exhaust system with an outer flow member is disclosed. The exhaust dispersion device includes a dispersion member capable of being disposed within the outer flow member. The dispersion member defines an axis and includes an upstream end and a downstream end. A cross section of the downstream end perpendicular to the axis is larger than a cross section of the upstream end perpendicular to the axis. The dispersion device also includes an aperture extending through the dispersion member. The aperture is coaxial with the axis. Flow of all exhaust gas through the outer flow member is divided between flow through the aperture and flow between the outer flow member and the dispersion member. The dispersion member is operable to divert the flow of the exhaust gas at least partially toward the outer flow member.
