Patent number: 7222979Abstract: An illuminated knob assembly includes a base. The base includes an annular track on an upper base surface of the base. A PC board is disposed in the track. The PC board includes a plurality of light sources disposed on an upper board surface of the board. A light transmitting plate is positioned over the PC board so as to transmit light therethrough from the light sources. A bezel is fitted over the light transmitting plate and includes gradated openings corresponding to different conditions of operation. The openings permit light to pass therethrough from the light transmitting plate and a knob is disposed adjacent the bezel. The knob includes a light pointer configured to receive and transmit light from the light transmitting plate.Type: GrantFiled: November 9, 2005Date of Patent: May 29, 2007Assignee: CFM CorporationInventors: David J. Popowich, Simon Treadwell, Kerwyn Prescod, Christopher J. Reis

Patent number: 7082942Abstract: A wood burner includes a wrapper. A firebox is positioned in the wrapper that defines a combustion chamber. An air inlet is placed in communication with an external air supply. The air inlet includes a conduit to conduct the external air to the combustion chamber and a second conduit. A manifold is positioned above the firebox. The manifold is in communication with the second conduit, and includes one or more manifold chambers for permitting the external air received thereby to become heated. A plurality of air tubes connect to the manifold to receive the heated external air from the manifold, each plurality of air tubes including a plurality of apertures to direct the heated external air into the combustion chamber adjacent an upper inner surface of the firebox.Type: GrantFiled: April 26, 2005Date of Patent: August 1, 2006Assignee: CFM CorporationInventors: Robert H. Buzzard, Ralph E. Morrison

Patent number: 7030391Abstract: An apparatus for irradiation of a fluid with UV light includes a tubular body consisting of UV-permeable material. The body includes a fluid chamber and openings for passage of fluid. A UV source is provided to subject the chamber to the UV light. Light baffles define an irradiated section of the chamber to prevent light penetration beyond the irradiated section while permitting the fluid to flow through. The apparatus is provided as a component in a housing having a modular design. The modules include a back cover for surface mounting. The body is mounted to the back cover. An inner cover is attached to the back cover. The inner cover includes the UV source and modular electronics. A front cover is attached to the inner and back cover. Heat sink elements are provided to control the heat produced in the apparatus.Type: GrantFiled: June 4, 2004Date of Patent: April 18, 2006Assignee: CFM CorporationInventor: Richard Zagrobelny

Patent number: 6757487Abstract: An electric fireplace designed to simulate a combustible fuel-burning fireplace. The electric fireplace includes a housing. A simulated firebox is positioned within the fireplace housing. The firebox contains a log and ember set having one or more artificial logs positioned above an artificial bed of embers. The fireplace also includes a mechanism for illuminating the underside of at least a portion of the artificial logs and the artificial bed of embers to create the illusion that the artificial logs and artificial bed of embers are burning. The fireplace further includes a flame simulation assembly for generating the appearance of simulated flames emanating from the artificial logs. The flame simulation assembly includes a light source, a light randomizer, a light filter screen, and a light diffuser screen.Type: GrantFiled: May 8, 2002Date of Patent: June 29, 2004Assignee: CFM CorporationInventors: Colm A. Martin, Donald R. Jamieson, Andy Luu, David Diep, Lam Van Nguyen
