Patent number: 9056276Abstract: An ozone converter that includes an outer housing having an inlet and an outlet is disclosed. In this embodiment the ozone converter includes a core disposed within the outer housing and a bypass cylinder disposed between the inlet and the outlet and that passes through the core such that air within the bypass cylinder does not contact the core. The ozone converter of this embodiment also includes a blocking sleeve that surrounds a portion of the bypass cylinder and that is moveable from a first position to a second position. When the bypass sleeve is in the first position air that enters in the inlet is directed by the blocking sleeve into the bypass cylinder and when it is in the second position air that enters the inlet is allowed to enter an outer passage between the bypass cylinder and the outer housing.Type: GrantFiled: October 17, 2011Date of Patent: June 16, 2015Assignee: Hamilton Sundstrand CorporationInventors: Donald E. Army, Frederick Peacos, III

Patent number: 9034255Abstract: The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.Type: GrantFiled: February 7, 2014Date of Patent: May 19, 2015Assignee: Lee Antimicrobial Solutions LLCInventor: James D.

Patent number: 9017606Abstract: Methods and apparatus for controlling odors in an enclosed space, such as a pit latrine, include providing an oxidizer, such as a catalytic heater and an optional mechanical ventilation unit, such as an inline fan, both flow connected to a vault (pit) of the latrine. The heater is also connected to a source of fuel, for example, propane. Fresh air is drawn through vents in the latrine housing and thereafter through toilets in the latrine and through the vault, providing oxygen for the reaction. The fan and/or oxidation process draws both fresh air and accompanying odorous compounds directly from the latrine and into the oxidizer wherein the odorous components are substantially destroyed.Type: GrantFiled: June 10, 2014Date of Patent: April 28, 2015Assignee: Environmental Purification, LLCInventors: Don S. Sifers, Kent A. Pennybaker

Patent number: 9004377Abstract: A scent producing vase assembly holds artificial flowers and produces a scent to fully simulate the presence of real flowers in the vase. The assembly includes a vase having a bottom wall and a perimeter wall coupled to and extending upwardly from a perimeter edge of the bottom wall. An upper edge of the perimeter wall defines an opening into an interior space of the vase. A housing is coupled to and extends through the bottom wall of the vase. A scent producing element is positioned in the housing. A channel has a lower end and an upper end. The lower end is in environmental communication with the scent producing element in the housing. An opening extends through the upper end of the channel wherein the scent producing element delivers a scent to ambient air around the upper end of the channel.Type: GrantFiled: June 17, 2013Date of Patent: April 14, 2015Inventor: Earl C. Whittaker
