In another embodiment of the present invention, the stacked chevron is asymmetrically disposed in the air vent housing so that a vane of the chevron extending towards the interior of the air vent is substantially perpendicular to the air vent housing and substantially parallel to the source of the flow of air.

Abstract: A modular air vent assembly kit can be used to cover duct openings that supply a flow of heated or cooled air to a room in addition to covering duct openings that receive return air from a room. The modular air vent assembly kit is comprised of a frame, a base, a damper mechanism, and two different face plates where the damper mechanism can be selectively assembled into the base depending on whether control through the air vent by operation of a damper is needed in the particular duct opening and where either of the two face plates may be selectively connected with the base where one face plate has a lattice and is used in combination with the damping mechanism and the other face plate has a series of louvers and is used when the damping mechanism is not used in the vent assembly. The frame is secured to an air duct opening and the base and attached face plate are removably attachable to the frame without the need for separate fasteners.

The system further includes at least one air flow distribution device establishing a predetermined flow rate distribution through electronic assemblies supported by the brackets.

Abstract: The invention comprises a ventilator for a glass block window that includes a window frame, a window sash pivotably mounted in the window frame and a screen also pivotably mounted in the window frame. The window sash is pivotable between a closed position and an open position such that when the window sash is in the open position, rain and snow and the like are resisted from passing through the ventilator and into the building which has the glass block window. The invention also encompasses providing a ventilator as described above without the screen. Finally, a screen for a window is also provided. The screen is pivotably mounted to the window frame of the window. This screen can be used not only for the ventilator but also for other types of windows.

Abstract: A fume hood includes a top, bottom sidewalls, front panel and a back panel that define an enclosed workspace. The fume hood also includes a movable sash for opening and closing an access opening. The fume hood also includes an air chamber having an inlet in the front panel. The air chamber includes a baffle system that evenly distributes the inlet air as the air travels through the air chamber. An unimpeded flow of air is discharged downward and away from the breathing zone of the technician and proximate to the sash to reduce the forward momentum of air trying to escape the fume hood. The fume hood provides a safe environment for the technician to work by enabling the fumes to stay contained in the fume hood under all working conditions. The air passes through the air chamber when the movable sash is positioned at a minimum height above the bottom of the fume hood.

The carbon monoxide sensor supplies power to the fan when a threshold level of carbon monoxide is detected. The fan includes a motor and a propeller which draws air into the fan unit, and expels the air through the vent. The sensor also includes an indicating device which produces an audio or visual indication that the threshold level has been reached. The indication continues until reset by a reset button.

Abstract: A roof ventilator comprises a duct 1 having a symmetrical hood 3 supported at its apex 4 by bearing 10. In the absence of wind, hood 3 is spaced from the upper end 2 of duct 1 with its depending skirt 6 surrounding upper end 2 However, wind from any direction causes the hood to tilt so that skirt 6 is lowered on the windward side thus increasing the ventilation rate and thus positioning hood 3 to deflect wind and wind-borne material from the ventilator opening.

Abstract: The present invention provides for an aroma-dispersing unit in the HVAC system of an automobile. The aroma-dispersing unit includes a passageway and an aroma cartridge housed in an aroma cartridge housing. The passageway includes a first portion, a low-pressure zone and a second portion. The low-pressure zone defines an opening. The aroma cartridge is in communication with the low-pressure zone. The aroma cartridge also defines an opening at the top of the aroma cartridge. The opening of the low-pressure zone and the opening of the aroma cartridge are alignable such that air passing through the low-pressure zone can extract aroma from the aroma cartridge. The aroma mixed air enters the second portion of the passageway where it is dispersed into the interior of the automobile. The amount of aroma extracted from the aroma cartridge can be varied by adjusting the proximity of the opening of the aroma cartridge relative to the opening of the low-pressure zone.

Abstract: A thermostat comprising an audible alarm or LCD, and sensing means for sensing at least one signal from at least one external carbon monoxide detector. The thermostat is configured to change the temperature setting to 50° F., and to trigger the audible alarm or flash a warning on the LCD display when receiving a signal from at least one carbon monoxide detector indicating the presence of a harmful level of carbon monoxide. The heating system's operation is not disabled but rather reduced to prevent potential freezing damage. The thermostat would continue the audible alarm, flashing warning and 50° F. temperature setting until it is reset.

Abstract: An air-conditioning system alternately produces a cooled air stratum and a heated air stratum as viewed from an air outlet opening, and the guide length a1 of a first guide wall is set from 0.05 time or more to 0.5 times or less than the length L1. The guide length a2 of a second guide wall is set from 0.05 time or more to 0.5 times or less than the length L2. Consequently if the air mixing chamber has a small capacity (the length parallel to the direction of air flow), it is possible to mix the heated air and the cooled air sufficiently.

Abstract: A method and apparatus for an air vent assembly is provided in which individual louvers and spacers are connected together to form chevron shaped channels that allow increased air flow while blocking the escape of direct light. The louvers are formed into a chevron shape that extends lengthwise from one end of the louver to another end of the louver. The spacers are chevron shaped and interlock or are bonded together with one another to secure the louvers and to provide a support structure such that additional spacers and louvers may be stacked together as needed to form an air vent for use in a given device.
