Patent number: 6755879Abstract: The invention relates to a bag filter device (12), which device enables collection and draining of particles of liquid from a gas, normally air, flowing through the bag filter (12). Such a bag filter (12) is normally used to trap solid particles from a gas flow, but where particles of liquid, in which there are for example salts or bacteria, are also trapped and possibly permeate the bag filter (12) and drip out on the downstream side thereof. Then the liquid may be carried further in the gas flow and have disadvantageous effect on equipment and surroundings. According to the invention such drawbacks can be avoided or reduced in that the filter material of a lower portion (18) and a bottom portion (19) in the continuation of the lower portion (18) of the bag filter (12) is formed in its entirety or in an outer filter layer (20) by a liquid-tight material. Possibly, the bottom portion (19) is provided with a liquid outlet (39), so that the liquid separated can collect and be drained from the bag filter (12).Type: GrantFiled: July 3, 2002Date of Patent: June 29, 2004Inventor: Jorn Watvedt

Patent number: 6129628Abstract: A roof vent comprises a base defining an air outlet/inlet portion, a cover having at least one exterior louvre for air flow, a side wall connecting the base and cover, and an interior louver between the exterior louvre and the air inlet/outlet portion with at least one and preferably two strips having slats configured such that matter passing through the vent must substantially traverse the interior louvre. The interior louvre is preferably perpendicular to the exterior louvre. The interior louvre contacts the base and the cover to provide support along with the side wall. A supporting rib may be added for additional support. The cover preferably has a second exterior louvre. A second interior louvre is located between the second exterior louvre and the air inlet/outlet portion such that matter must substantially traverse the second interior louvre if it is to pass through the vent via the second exterior louvre.Type: GrantFiled: April 23, 1999Date of Patent: October 10, 2000Assignees: Harry O'Hagin, Carolina O'HaginInventors: Harry O'Hagin, Carolina O'Hagin

Patent number: 5765329Abstract: A roof construction includes spaced apart corrugated sheets held in spaced relationship by a plurality of spacers, the corrugated sheets both including apertures for dissipating heat contained in the hot air between the sheets into atmosphere and for guiding hot air from below the lower sheet into the space between the sheets for ultimate expansion and discharge into atmosphere. The apertures may be offset to prevent flow of moisture directly through the apertures and other devices may be utilized to prevent direct flow of moisture into the space below the roof assembly.Type: GrantFiled: July 31, 1997Date of Patent: June 16, 1998Inventor: Chihshu Huang

Patent number: 5632678Abstract: A roof vent which is mounted on a roof to vent a clothes dryer. According to the roof vent, a screen is located to the outside of the vent and it is hinged thereto at a forward edge of the vent to completely enclose the space that is formed between the opening and the base plate of the vent. Because of this hinge, the screen may swing upwardly for easy cleaning. There is also a provision for locking the screen in its closed position to prevent rattling and to prevent dislodging by other forces, such as, animals or high winds.Type: GrantFiled: May 28, 1996Date of Patent: May 27, 1997Inventor: John G. Doelfel

Patent number: 5630752Abstract: A single sheet of relatively stiff material is formed with a flat rim surrounding a raised area except along one open side or edge with the raised area having a low elevation so as to present a low profile when placed on the roof and is in air communication with an opening through the roof with the open edge providing an opening for air passage to the atmosphere and having a baffle at the open edge to prevent foreign materials and rain from entering and having tabs at the open edge for grasping the edge of a covering roof shingle. Preferably the vent is triangular in top plan so that the apex angle of the vent opposite the open edge can be easily inserted under a shingle between the nails which hold the shingle in place.Type: GrantFiled: December 11, 1995Date of Patent: May 20, 1997Inventor: Peter J. Gubash

Patent number: 5549513Abstract: A roof structure, which has a plurality of concrete tiles arranged in overlapping rows on a roof support structure, is provided with a roof ventilation device for venting the underside of the roof support structure. The device receives and integrates with a plurality of shortened tiles in an upper row so as not to disturb the appearance and continuity of the roof structure. A hollow upper portion of the roof ventilation device forms part of a ventilation path which extends from outside the roof structure to one or more apertures in the roof support structure and has a plurality of baffles disposed therein for preventing entry of rain water. A length of mesh mounted within an inside portion of the roof ventilation device at the back of the upper portion prevents entry of insects, vermin and debris, while foam strips mounted on the mesh seal the space above tiles in a lower row.Type: GrantFiled: October 13, 1993Date of Patent: August 27, 1996Assignee: Monier Roof Tile Inc.Inventors: John F.
