A viewport for a combustion zone includes an inner casing having a flange extending into the combustion zone. A first layer of ceramic fiber insulation is exterior to the inner casing. A middle casing includes two panes of quartz glass separated by traverse plates. A second layer of ceramic fiber insulation is exterior to the middle casing. An outer casing is positioned to the exterior of the second layer of insulation. The middle casing includes L-shaped ledges having third and fourth layers of ceramic insulation. The panes of glass are each positioned between layers of insulation and the insulation positioned in the L-shaped ledges. The viewport is modular enabling the separation of the first layer of insulation, the middle casing, the second layer of insulation and the outer casing from the combustion zone for maintenance or repair. The viewport minimizes heat migration to the outer casing during use.

Disclosed herein is a portable roaster used when outdoor cooking or camping is enjoyed. The portable roaster with improved portability and handleability can be changed into a single briefcase form so that it is easy for the user to carry it, can accommodate a windshield, a vertical transfer part, a charcoal plate, and a grill inside the body of the portable roaster so that meat can be grilled and eaten by, e.g., a barbecue grilling method outdoors through easy assembly, it is convenient to store portable roaster in a vehicle or warehouse, and the handling of the portable roaster is very convenient, and allows a cover to be used as a substitute for a table so that the portable roaster is highly versatile.

The object of the present invention is an integrally bonded composite component, a method for the production thereof, and the use thereof. The invention particularly relates to integrally bonded transparent ceramic composite components, to a method for the production of such ceramic composite components, and to the use thereof.

A streamer type flame simulation device includes a casing, some cross-flow fans disposed inside the casing, a first streamer, a second streamer, a supplementary air-supplying device and a light source. The supplementary air-supplying device is arranged in the split joint area between the two cross-flow fans. Since a supplementary air-supplying device is provided between two cross-flow fans for supplying air, the deficiency where air was unable to deliver at the space occupied by the drive motor of the cross-flow fans can be avoided. Various parts of the first streamer and the second streamer can be blown, thus preventing the flame from being cut off and enhancing the overall coordination, which greatly improves the viewing effect of the flame area.

A camera assembly includes an insulating block for mounting the camera against a surface in contact therewith and aligned with an opening through the surface. The insulating block defines an aperture therethrough, a lower side of the aperture being aligned with the opening in the surface. The assembly further includes a sink washer mounted to the insulating block in partial contact therewith and extending outward from the top side of the aperture. A camera is mounted to the sink washer and has a lens directed through the aperture in the insulating block and through the opening in the surface. A glass substrate is coupled within the lower side of the aperture to enclose an air gap within the aperture between the glass substrate and a housing of the camera.

A firebox is provided for use in a gas fireplace, the firebox comprising: a back which includes at least one combustion fan aperture, an upper end and a lower end and a length therebetween, a pair of sides, each side including an upper end, a lower end, a first riser which has an inner section and an outer section, the inner section attached to the back, a first flange, which is parallel to the back and extends outward from the back, and a second riser, wherein the outer section of the first riser, the first flange and the second riser extend above the upper end of the back and below the lower end of the back; a top which is attached to the inner section of the first risers and to the back at the upper end; and a base which is attached to the inner section of the first risers and to the back above the combustion fan aperture, to define an opening. The fireplace is also provided.
