Patent number: 8302943Abstract: A humidifier pad assembly for a humidifier that is configured for adding humidity to an air stream of an HVAC system of a building or other structure. The humidifier pad assembly may include a frame for holding a replaceable humidifier pad within the housing of the humidifier. The frame may be structured to hold the replaceable humidifier pad within the housing such that a back major surface of the replaceable humidifier pad generally faces the back side of the housing, and a front opposing major surface of the humidifier pad generally faces the front side of the housing. The frame may further be structured to permit removal and replacement of the replaceable humidifier pad through the front side of the frame. In some cases, the housing may be configured such that the frame (and the replaceable humidifier pad) may be slid out of apertures in the right side and/or left side of the housing.Type: GrantFiled: September 23, 2009Date of Patent: November 6, 2012Assignee: Honeywell International Inc.Inventors: Bin Wang, Xin Hua Cao, Brad Terlson, David Quam

Patent number: 8292270Abstract: A humidifier for adding humidity to an air stream of an HVAC system includes a housing configured to be mounted to a surface of an HVAC duct. The housing may be configured to hold a humidifier pad in an operating position. The housing may direct air through the humidifier pad from a first major surface to a second major surface of the pad. In the operating position, the first and second major surfaces of the humidifier pad may be substantially non-parallel with the surface of the HVAC duct when the housing is mounted to the surface of the HVAC duct. In some cases, this may provide a more compact design. In some cases, a centrifugal fan, rather than an axial fan, may be used to draw air into the humidifier from the HVAC duct. The use of a centrifugal fan may reduce the noise associated with the operation of the humidifier.Type: GrantFiled: September 23, 2009Date of Patent: October 23, 2012Assignee: Honeywell International Inc.Inventors: Brad Terlson, Xin Hua Cao, Xue Dong Li, Bin Wang

Patent number: 8231112Abstract: A humidifier for adding humidity to an air stream of an HVAC system includes a housing configured to be mounted to a surface of an HVAC duct. A back side of the housing may be positioned adjacent to an opening in the surface of the HVAC duct, and the housing may be configured to hold a humidifier pad in an operating position. The housing may define a first air flow path from a first side of the humidifier pad to the opening in the surface of the HVAC duct when the housing is mounted to the surface of the HVAC duct. The housing may further define a second air flow path from a second side of the humidifier pad to a bypass aperture. At least part of the second air flow path may be defined by a bypass duct member. The bypass duct member may be field-reconfigurable between at least a first position resulting in the bypass aperture being located at a first location, and a second position resulting in the bypass aperture being located at a second location.Type: GrantFiled: September 23, 2009Date of Patent: July 31, 2012Assignee: Honeywell International Inc.Inventors: Xinhui Hua Cao, Stephane Joseph Pierre Beland, Bin Wang, Jason Ableitner, Brad Terlson, Evelyne Tremblay, Vincent Boutin

Patent number: 6420571Abstract: The present invention relates to methods for preparing 2,2-dimethyl-5-acyloxy -10-propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (5) and 2,2-dimethyl-5-hydroxy-10 -propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (6) and their use as intermediates for the synthesis of antiviral calanolide compounds. For example, Fries rearrangement on compound 5 or Friedel-Crafts reaction on 6, yields intermediate 2,2-dimethyl-5-hydroxy -6-propionyl-10-propyl-2H,8H-benzo[1,2-b:3,4-b′]dipyran-8-one (4), which, in turn, can be converted to (+)-calanolide A and (−)-calanolide B. The coupling of compound 6 with the appropriate chiral molecule under Mitsunobu or nucleophilic displacement leads to the asymmetric synthesis of antiviral calanolide compounds.Type: GrantFiled: July 31, 2001Date of Patent: July 16, 2002Assignee: Sarawak MediChem Pharmaceuticals, Inc.Inventors: Ze-Qi Xu, Hongwei Yuan, Jennifer Crabb, Raghu Samy, Ailing Li, Hua Cao
