Patent number: 8662971Abstract: The door insert of the present invention balances air pressure in a closed environment. It includes a frame that defines a slot. A pair of tabs emanates from opposing sides of the frame to attach the frame to a door. Media, which has a plurality of apertures therethrough, resides in the slot. The frame, with media installed therein resides within a notch in an edge of a door. Air is permitted to flow through the door insert to balance the air pressure within an environment divided by the door. The frame is preferably ABS plastic and the media is preferably paper. The appearance of the frame and media may be modified to aesthetically match the decor of the door, door hardware and surrounding environment.Type: GrantFiled: January 28, 2011Date of Patent: March 4, 2014Assignee: Tamarack Technologies, Inc.Inventor: Nelson Albert Warner

Publication number: 20140034046Abstract: Vent terminal apparatus and methods are provided for covering vent pipes in an HVAC system, e.g., air intake and combustion gas exhaust pipes of a furnace or boiler. The vent terminal includes a body defining a shielded air inlet configured to fluidly communicate with an air intake pipe, and an exhaust opening configured to fluidly communicate with an exhaust pipe. The vent terminal also includes a nozzle configured to couple with the body and defining a flowpath therethrough. When the exhaust opening of the body is in fluid communication with the exhaust pipe and the nozzle is coupled with the body, the flowpath is in fluid communication with the exhaust pipe via the exhaust opening and the flowpath is oriented at an acute angle relative to the exhaust pipe.Type: ApplicationFiled: July 30, 2013Publication date: February 6, 2014Applicant: Carrier CorporationInventors: David Warmuth, Gary E.

Patent number: 6574932Abstract: An embeddable air duct block includes a tubular member extending between a pair of rectangular plate members spaced from each other. The tubular member has a pair of open ends and an interior passageway. One plate member has an inner surface coupled to one open end and a plurality of holes in fluid communication with the interior passageway. The other plate member is coupled to the tubular member and has a duct opening aligned with the interior passageway. Two cement cavities are preferably formed on opposite sides of the tubular member. An air duct is formed in a concrete block wall by installing and securing the air duct block in the concrete block wall. The blocks are coupled together by cementing slurry poured into the cavities. Optionally, reinforcing bars can also be utilized within the cement cavities and at least one cavity of the concrete block wall.Type: GrantFiled: March 9, 2001Date of Patent: June 10, 2003Assignee: Steel Block, Inc.Inventors: Harry R. Layne, Harbert S. Gregory

Patent number: 6109339Abstract: A heating system uses a dynamic thermal stabilizer for receiving, mixing, holding and outputting a circulating heat exchange liquid in a fashion similar to the use of a flywheel in the mechanical arts. Liquid is returned to the dynamic thermal stabilizer from both an input heat exchange unit and an output heat exchange unit. A two pump system affords a simple tee fitting arrangement that provides room air heating by directly using hot liquid either from the dynamic thermal stabilizer or directly (and at higher temperature) from the input heat exchange unit itself to automatically achieve an additional boost of room heat using higher temperature liquid. The system can also provide initial short draws of domestic hot water from the dynamic thermal stabilizer alone or long draws of hot water by using the input heat exchange unit as a further source of heat input.Type: GrantFiled: November 8, 1996Date of Patent: August 29, 2000Assignee: First Company, Inc.Inventors: Sherwood G. Talbert, David A. Ball, Jan B. Yates, Stephen E. Petty, Steve Grimes

Patent number: 5299399Abstract: A dual glazing window having a removable glazing panel is provided with a breather system connecting the air chamber between the glazing panels with the outside ambient air by routing an outwardly facing channel into the window rail or stile member either on its end edge or side face. The abutting rail or stile member will close the open side of the channel in the end edge while the adjacent glazing panel closes the channel in the side face. A breather sleeve is press fitted into the channel to protect the wood from absorbing moisture.Type: GrantFiled: November 18, 1991Date of Patent: April 5, 1994Assignee: Pella CorporationInventors: Bruce A.
