Abstract: A positionable exhaust apparatus with an exhaust outlet having a first bore extending along a length of the exhaust outlet. The first bore having a longitudinal axis extending the length thereof and an exhaust outlet tip coupled to the exhaust outlet. The exhaust outlet tip having a second bore with at least a portion of the second bore substantially aligned with the first bore of the exhaust outlet. An actuator coupled with the exhaust outlet and the exhaust outlet tip with at least a portion of the exhaust outlet tip to rotate the exhaust outlet tip relative to the exhaust outlet. The exhaust outlet tip rotatable three hundred and sixty degrees about the longitudinal axis of the exhaust outlet.

Abstract: An air extractor for a vehicle, the air extractor comprising a frame having a top portion, a bottom portion, a left side portion and a right side portion surrounding a central air passage, the frame having an inlet side for receiving air from a passenger compartment of the vehicle and having an outlet side for exhausting the air from the passenger compartment of the vehicle, a gasket to seal the frame to the vehicle, a plurality of spoilers supported by the frame and disposed within the central air passage and a plurality of flaps pivotally mounted on the outlet side to pivot between a closed position that inhibits airflow and an open position that permits airflow, wherein each of the flaps comprises a plurality of bumpers to attenuate slap noise of the flaps and wherein each of the flaps further comprises a skirt to minimize air leakage.

Abstract: A stand-alone shower system includes a cylindrical shower compartment with a transparent, translucent, or opaque wall and door, one or more specially configured shower nozzles, an optional storage compartment, and an optional surrounding cylindrical privacy curtain.

Abstract: An outdoor grill adjustable vented chimney cap assembly having a tubular base member with vent openings and a cap member having a cover member and a tubular body with vent openings, the base member being adapted to be mounted onto the chimney of a grill, the cap member being mounted onto the base member whereby the cap member can be rotated relative to the base member such that base vent members can be adjusted to control the amount of hot gases escaping from the grill.

Abstract: An exhaust pipe cover adapted to resist wind-induced uplift and entry of any accompanying and/or independent rain, snow, dirt, dust, and/or other foreign matter, into the exhaust pipe and communicating engine, wherein such a device may be retrofitted to existing vertically-disposed exhaust pipes extending from engines incorporated into machinery such as, for exemplary purposes only, tractors, trucks, irrigation motors, generators, and the like.

Abstract: A vent apparatus for an enclosed space such as that within a structure or a vehicle, including a vent tube having a first end that extends outside of the closed space and a second end that is connected to the enclosed space and a vent cap removably coupled to the vent tube and capable of pivoting or swiveling with respect to the vent tube to prevent water from entering the reservoir through the vent tube.

Abstract: An environmental exhaust duct adapted to be mounted on a roof allows for exhaust gases to escape while preventing water and debris from entering the building. The exhaust duct has a flap which is closed over the duct by gravity, and which pivots upwards when exhaust gases are released. A cap over the duct prevents water and debris from entering the air shaft when the flap is open.

Abstract: A vent termination assembly for a vertical pipe, stack or tube including a hinged flapper to normally close the end of said vent termination assembly and at least one downwardly sloping normally open to the atmosphere side pipe bevelled to discharge generally upward. The flapper contains energy adsorbing side beams to reduce velocity of the flapper during opening.

Abstract: An incinerator chimney stack valve mechanism which normally prevents the flow of fluid from the chimney stack. The incinerator chimney stack valve mechanism is mounted upon the chimney stack adjacent an opening in the chimney stack. A closure member is mounted upon an arm member and is movable toward and away from the opening in the chimney stack. An engagement member is mounted upon a second arm member. The second arm member is connected to a motor member which moves the second arm member for engagement of the engagement with the first arm member for movement of the closure member with respect to the opening in the chimney stack. The weight of the engagement member is sufficient to move the first arm member and thereby move the closure member with respect to the opening in the chimney stack if the motor member should fail to function properly.
