Abstract: A heatproof cloth forms multiple layers of laminated fabrics for resisting the high-temperature, comprising a high-temperature shielding fiber fabric which shields external heat, a first carbon felt fabric which distributes the heat transmitted through the high-temperature shielding fiber fabric, an aluminum vapor-deposited fabric which shields the heat distributed by the first carbon felt fabric, a second carbon felt fabric which distributes the heat transmitted through the aluminum vapor-deposited fabric, an aluminum vapor-deposited heat-resistant fabric which shields and distributes the heat distributed by the second carbon felt fabric, an aramid felt fabric which distributes the heat transmitted through the aluminum vapor-deposited heat-resistant fabric, and aramid fabric which shields the heat distributed by aramid felt fabric. Since heat is shielded and distributed repeatedly through three steps, the transmission of external heat is effectively prevented.

Abstract: Disclosed herein is a stabproof and bulletproof panel. The stabproof and bulletproof panel includes a bulletproof panel 40 and a plurality of stabproof panels 60. The bulletproof panel 40 is comprised of a front plate 45, a plurality of high density polyethylene films 44 stacked with one on top of another for dispersing impact energy, and a rear plate 46 formed by sewing together a plurality of aromatic polyamide woven fabrics for minimizing frictional heat and deformation. The front plate 45 consists of a plurality of aromatic polyamide woven fabrics 41, a felt 50 formed by forcibly inserting thin aromatic polyamide fibers or high density polyethylene fibers 52 and a shock-absorbing member 51 into a scrim woven in the form of a net using aromatic polyamide fibers or high density polyethylene yarn, and a plurality of aromatic polyamide woven fabrics 43. The stabproof panels 60 are brought into tight contact with the front surface of the bulletproof panel 40.

Abstract: A pellet fuel burner includes a compact thermally insulated firebox for providing hot gases to a boiler, furnace or dryer. The apparatus includes a grate that includes a reciprocating arm for removing clinkers and ash from the grate. Pellet fuel feed is provided by a hopper that is isolated from the firebox by an airlock. A combustion air manifold is provided around the firebox to preheat primary and secondary combustion air.

Abstract: A gas burning imitation log assembly (18) including an imitation log (20) carried by a supply conduit (24) is disclosed. Supply conduit (24) receives gas from a gas source (26). The gas contained in supply conduit (24) escapes through aligned slots (34) passing through supply conduit (24) and log (20). In one embodiment of the invention, supply conduit (24) includes an outer sleeve (48) and an inner sleeve (46) which define a gas region (32). In an alternative embodiment of the invention, supply conduit (24) is not used. Gas is conveyed into log (20) which contains a diffusing layer (52) that overlays slots (34) to uniformly diffuse the gas through log (20).

Abstract: Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate of equally or unequally spaced rods. The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in mounts that could reduce the flow of combustion gas into the fire. In one embodiment, an ignitor rod is provided as one of the spaced rods in the grate assembly. By applying power to the ignitor rod, the rod is raised to a sufficient temperature to ignite unburned biomass pellets in proximity to the ignitor rod.

The design of the rods serves to prevent the ash and clinkers from accumulating on the grate in amounts that could reduce the flow of combustion gas into the fire. In one embodiment, the rods define a surface that serves to distribute unburned fuel pellets from a location where they are deposited from a fuel feed conduit.

Abstract: Stoves fueled by biomass pellets are provided with a grate assembly that supports the pellets for combustion and directs combustion gas into the fire. The grate assembly includes a passive grate and a moveable elongate blade spaced above the upper surface of the grate to direct ash and clinkers through a plurality of elongate slots in the grate. The design of the planar plate and the movement of the blade serves to prevent the ash and clinkers from accumulating on the grate in amounts that could block the elongate slots and reduce the flow of combustion gas into the fire.
