Abstract: A wind guiding cover, mounted on a fan, includes a rotating ring and a plurality of slats. The rotating ring is pivoted to the fan, and has an opening for an air flow generated by the fan to pass through. The rotating ring has a weight portion for offsetting the center of gravity of the rotating ring and normally maintaining the rotating ring at a static equilibrium position. The slats are pivoted to the rotating ring and arranged at the opening. When the fan operates, the slats are lifted by the air flow to open the opening. When the fan stops operating, the slats cover the opening under the gravity.

Abstract: An appliance assembly that can provide multiple independently positionable appliances, such as fans. The appliance assembly includes a base support, a frame coupled to the base support, and a number of appliances each contained within an appliance housing. Each appliance housing is rotatably mounted to an outer gimbal such that it is rotatable about a first axis, and each outer gimbal is mounted to the frame such that it is rotatable about a second axis. The appliance assembly can provide two degrees of freedom for positioning each of the number of appliances. The frame, outer gimbals, and appliance housing can be formed in a variety of shapes. The appliance assembly can be used, for example, with any product where it is desirable to have multiple independently positionable assemblies, such as fans, speakers, microphones, lights, and heaters.

Abstract: A window assembly comprises a frame into which is removably mounted a fan assembly. The fan assembly includes at least one fan mounted in an opening through a mounting plate. The mounting plate is removably secured to the window assembly by a screen, which is removably secured to the window frame. The inventive window assembly is particularly useful for existing glass block window and vent designs.

Abstract: An electric exhaust fan has generally conventional components and is normally mounted in a window pane in known manner. The fan has a door, consisting of two rotatably mounted shells 14 and 15, that closes off a front face 11 of the fan. The door is opened and closed by a motor 24 that has a drive gear 23. The drive gear 23 engages gearing 14A and 15A formed on respective side walls of the shells. Opposite side walls of the shells have gearing 14B and 15B that mesh with one another. Also, the door remains open, once it has been fully opened, without requiring to supply power to the motor 24 to keep the door open.

Abstract: An air circulator unit with adjustable size is provided including a housing situated within a window frame. The housing includes a pair of halves each defining an interior space, an open front face and an open rear face. The housing further includes a length adjuster having a pair of ends coupled between the halves of the housing with a plurality of bellows formed therebetween for allowing the movement of the halves along a single axis. At least one fan unit is mounted within the interior space of each of the halves for directing air between the open faces of the housing.

Abstract: The invention relates to a filtering device with a filter housing which can accept a filter mat, is covered with a lamella grid on the outlet side and is fitted in an aperture in a mounting wall.

The fan and heating element are selectively powered by the vehicle electrical system through an on-off switch.

Abstract: An affordable ventilation controller comprises a low cost and very stable carbon dioxide sensor and a remote-controlled louvered suction fan equipped with an air filter. The ventilation controller operates independently of any existing heating or cooling system that might be present in a closed room. The carbon dioxide sensor measures accurately the gas concentration level in parts-per-million (ppm's) as a ventilation index. When a predetermined ventilation index is exceeded indicative of bad ventilation, a remote-controlled suction fan equipped with a louver and an air filter is activated to draw in fresh air from the outside in order to regulate the CO.sub.2 concentration and provide good ventilation. However, if an exceedingly high concentration of CO.sub.2 is sensed, the controller inhibits the control signal to the suction fan, since such a high level might indicate the presence of a fire.
