Patent number: 8672614Abstract: Exhaust apparatus for exhausting “dirty” exhaust gases accept a core flow of such exhaust gases and combine that with an annularly-surrounding “rooftop” flow of ambient air for diluting the exhaust gases as well as expelling the diluted flow in a forcibly expelled plume in order to ensure that the “effective” expulsion distance of the expelled diluted flow is at least the physical length of the exhaust apparatus plus the gains gotten from efflux velocity and flowrate.Type: GrantFiled: February 2, 2009Date of Patent: March 18, 2014Assignee: Loren Cook CompanyInventor: Erich R. Fitzpatrick

Patent number: 8658944Abstract: An apparatus for preventing the accumulation of snow, ice, frost, hail or the like from obstructing the flow of primary air, air or the exhaust into or out of a high-efficiency sealed combustion condensing furnace is provided. The apparatus is also suitable to prevent leaves, animals or other debris from becoming trapped within the air flow pipes of the furnace. The apparatus has a screen which may be electrically connected to a heating device. The apparatus may further be attached to a thermostat to automatically turn the heating device on or off at preset temperatures. The apparatus may be incorporated into new pipes or may be attached onto existing pipes.Type: GrantFiled: August 20, 2010Date of Patent: February 25, 2014Inventors: Daniel Clemenz, Gary Apfelbaum

Patent number: 7708625Abstract: An inlet and/or outlet air hood comprising vertical storm louvers is provided that is particularly well suited for use on a Mobile Offshore Drilling Unit and other marine vessels, although its use is not so limited. The hood may comprise a basic cube shape, which affords a smaller projected footprint than conventional round- or mushroom-shaped hoods and may incorporate an internal flow shaper, such as an inlet/outlet bell, to reduce airflow resistance. In addition, the hood may be configured to incorporate an internal valve or baffle to create a watertight closure.Type: GrantFiled: July 5, 2007Date of Patent: May 4, 2010Assignee: L.C. Eldridge Sales Co., Ltd.Inventors: Gary T Leseman, Joseph B Davis

Patent number: 6716099Abstract: An apparatus for the collection of contaminants from the exit vent of an air ventilation vent. The apparatus includes a trough adjacent the duct forming the exit vent. The apparatus is constructed and arranged such that no contaminants exiting the vent can pass between the apparatus and the duct. The apparatus may also include a cover placed over the trough. The cover is constructed and arranged to allow contaminants to pass between the duct forming the exit vent and the cover and into the trough.Type: GrantFiled: June 28, 2002Date of Patent: April 6, 2004Assignee: Enviromatic Corporation of America, Inc.Inventors: Donald F. Pfleiderer, Leland R. Gute

Patent number: 6138666Abstract: A heater includes a housing having an angled top, a fan having a discharge disposed parallel to the angled top of the housing, and a baffle for laminarizing airflow through the heater. The heater may also create airflow through a cover, across a housing, a heat sensitive component, and/or a raceway, and into a housing inlet. The heater may include a manifold having at least one coupling member that slidingly engages and disengages a burner. Methods for propelling combustion air through a heater, laminarizing combustion airflow in a heater, improving the efficiency of a heater, and converting a heater to make it compatible with a different fuel are also disclosed.Type: GrantFiled: November 10, 1998Date of Patent: October 31, 2000Assignee: Teledyne Technologies IncorporatedInventor: Michael J.
