  • Patent number: 6974380
    Abstract: The invention is an air handling system that is shared between a laboratory and offices within the same building. The normally separate office and lab systems have been combined by way of an air return system that draws air from the offices and feeds into both the office and lab air supplies. The re-circulation of the office air draws more fresh outside air into and lessens requirements for the heating and cooling systems for the offices.

  • Patent number: 6974379
    Abstract: A vent, together with one or more building apertures, provides a route for gas exchange through a building surface. The vent comprises a base member having a vent aperture therethrough and a generally planar mounting flange on its perimeter. The base member may be mounted within a building surface such that the mounting flange extends between an internal building surface layer and one or more external building surface layers and the vent aperture is in fluid communication with the one or more building apertures. The vent also comprises a vent cover which is removably mountable to the base member when the base member is mounted within the building surface. The vent cover has a hood member which projects downwardly and outwardly from the base member for conveying moisture away from the vent aperture. A bottom drainage flange may project outwardly and downwardly from beneath the vent aperture to convey moisture downwardly and outwardly past an outermost one of the one or more external building layers.

  • Patent number: 6971585
    Abstract: A system and method of protecting production tooling used in semiconductor fabrication from potentially damaging low temperatures or sudden temperature drops during periods of primary power outage and low outside temperatures. The boilers and pumps at a central utility plant (CUP) which normally provide superheated water under pressure to heat exchangers in each building to be heated are cut back to a fraction of their normal heating capacity during periods of primary power outage, although air continues to be exhausted from, and outside air taken into fabrication buildings. In the present invention, an additional heat exchanger is placed in each building which houses production tooling, and the coolant from the engine used to drive the generator for powering the air handling equipment in the building may be selectively directed through one of the flow paths of the second heat exchanger.

  • Patent number: 6958011
    Abstract: A fabric air duct with main discharge openings includes additional, much smaller openings that help ventilate the surface of the duct. Ventilating the surface of the duct with a slight yet even amount of airflow helps inhibit the accumulation of condensate and dust on the surface of the duct. In some embodiments, the duct includes a pliable sheet consisting of a rather porous fabric base material. To achieve an appropriately low level of airflow, a plastic coating on the fabric reduces, but does not eliminate the fabric's porosity. A calendering process then reduces the porosity even further. In some embodiments, the calendering process occurs before the plastic coating process. In other embodiments, the pliable sheet is substantially air impermeable, except for its main discharge openings. The sheet is then perforated with numerous smaller openings to achieve the desired amount of surface ventilation.

  • Patent number: 6951513
    Abstract: An enclosure for operationally retaining a plurality of electronic modules has a housing comprising front, side, upper, lower, and rear walls, and housing enclosing an inner volume. The enclosure has an inner wall running between the side walls and attached to the lower wall. The inner wall is positioned between the front and back walls, and splits the inner volume into a first inner volume and a second inner volume. The inner wall extends from the bottom wall to a height less than that of the height of said top wall, and defines an opening between the first inner volume and the second inner volume. An exhaust vent is disposed through the rear wall of the housing. Openings exist in the housing into the first inner volume. This allows an airflow into the first inner chamber. An environmental flow mechanism, such as a fan, is coupled in proximity to the exhaust vent.

  • Patent number: 6945867
    Abstract: A grating assembly drive means is connected to control the movement of the movable grating between OPEN and CLOSED positions relative to a fixed grating. The drive means moves the movable grating through yieldable connection when moving toward CLOSED position, whereby when such movement is blocked by a foreign object the movable grating stops without damaging the object or the drive. On the other hand movement by the drive means toward OPEN position is direct after removal of any slack caused by a previous yielding.

  • Patent number: 6939219
    Abstract: A ventilator in a cover for a deck on a boat. A base of the ventilator has first openings therein through which the deck is connected to a chamber formed by the first intermediary member and the base. A motor retained in the first intermediary member has a fan that is located in the chamber to expel air from the deck to the surrounding environment by way of second openings therein and third openings in a second intermediary member. A projection in the first intermediary member receives a connector from a solar panel that is located in an end member. The end member is joined to the first intermediary member to align the second and third openings with the chamber and the connector with the motor such that the fan is activated when light is received by the solar panel and air is continually thereafter drawn from the deck.

  • Patent number: 6929190
    Abstract: A multi-purpose heating unit is sized and configured to be used with a variety of attachments or devices to perform various functions such as heating, cooking and providing light. In particular, the multi-purpose heating unit includes a heat source which can be used with a water heating attachment, an air heating attachment, a cooking attachment, and/or a light source attachment. Each of these attachments is configured to be selectively attachable to the heat source. Advantageously, because the same heat source is used in connection with these different devices, this decreases the size, weight and storage volume of these devices. This also allows the heating unit and some or all of the desired attachments or devices to be stored and transported in a relatively small container.
