Patent number: 5924922Abstract: A ceiling ventilation inlet includes a housing having an air inlet aperture, an air outlet aperture, and a baffle supported for linear movement adjacent the air outlet aperture. A spring is positioned such that the baffle moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle and enters the livestock confinement building in a 360 degree dispersion pattern. The spring causes the baffle to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment the greater the air outlet area becomes. Since the inlet is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate.Type: GrantFiled: November 15, 1996Date of Patent: July 20, 1999Assignee: Osborne Industries, Inc.Inventors: George R. Eakin, Ronald M. Thibault

Patent number: 5261857Abstract: A ceiling vent diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent. The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch associated with the vane directs the outflow of air and also laterally disperses air within the vent. The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.Type: GrantFiled: June 23, 1992Date of Patent: November 16, 1993Inventors: Bart Petterson, James Cherrington, Michael Cherrington, Garry Rose
