Patent number: 8778065Abstract: In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the condensable fluid into the bath. Energy from condensation is recovered to a coolant in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.Type: GrantFiled: August 26, 2013Date of Patent: July 15, 2014Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum & MineralsInventors: Prakash Narayan Govindan, Gregory P. Thiel, Ronan K. McGovern, John H. Lienhard, Mostafa Hamed Elsharqawy

Patent number: 8758466Abstract: A device in a pipe has an annular partition spaced radially inwardly from an inner face of the pipe and defining therewith an upstream annular space opening axially upstream of the direction into the pipe such that a secondary gas stream is separated from the primary gas stream along with a liquid film on the inner surface, a downstream annular space larger than the upstream annular space, and a droplet separator opening into the downstream annular space. The separator has a plurality of lamellas, a condensate sump, and a drain, so that the edge film intercepted by the partition into the upstream space passes therefrom into the downstream space and therefrom through the separator such that the liquid of the film flows into the sump and out the drain and the secondary gas stream passes out of the separator.Type: GrantFiled: February 18, 2011Date of Patent: June 24, 2014Assignee: Munters Euroform GmbHInventor: Matthias Jansen

Patent number: 8523985Abstract: In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the fluid into the bath. Energy from condensation is recovered to a liquid composition in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.Type: GrantFiled: July 12, 2012Date of Patent: September 3, 2013Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum and MineralsInventors: Prakash Narayan Govindan, Gregory P.

Patent number: 7115155Abstract: An air filtration and aromatizer apparatus which includes a housing, a motor in the housing with a fan for drawing air through an inlet toward an outlet through a pollution-collecting chamber, and an elongated hollow tubular perforated member having an upper end connected to the motor output shaft and a lower end disposed in a bath of water. The hollow tubular member is formed in such a manner that as it is rotated by the motor, it draws water from the container under the influence of centrifugal force, and then forces the water through the perforations to form a mist or rain-like atmosphere in the path of motion of the air passing from the housing inlet toward the housing outlet.Type: GrantFiled: December 4, 2003Date of Patent: October 3, 2006Inventor: Ronald Donald Stead

Patent number: 6078846Abstract: The non-contact sensor employs a structured light source that emits light in a predefined planar configuration and an optical receiver for reading reflected light produced by the structured light source within a predefined field of view. A tetrahedron target structure includes a three-dimensional framework that defines at least three non-collinear, non-coplanar structural lines each simultaneously visible to the sensor. A calibration system is coupled to the gauging system and the non-contact sensor for calibrating the gauging system by evaluating the geometric relationship of the structured light reflected from the structural lines of the target structure to determine the position and orientation of the target structure and then correlating the structural lines to the gauging system.Type: GrantFiled: January 19, 1998Date of Patent: June 20, 2000Assignee: Perceptron, Inc.Inventors: Dale R.
