Abstract: This invention relates to a gas burner which employs a two stage flame stabilizer. At low input rates, a fully aerated flame is stabilized at the surface of a porous material. At higher input rates, the flame blows off and is held by flame stabilization tabs. Such structures of this type, generally, operate over a very wide range of input rates and employ a highly aerated flame which reduces the flame temperature, slows NOx production, and increases the overall reaction rate by shortening the flame while reducing carbon monoxide (CO) caused by flame impingement.

Abstract: In a torch which uses oxygen and a fuel gas, a first flashback assembly and a second flashback assembly are formed as an integral part of the torch handle. Each flashback assembly includes three primary components as follows: a porous metal flashback arrestor, a retainer and a check valve subassembly. In the preferred embodiment, the porous metal flashback arrestor is mounted on one end of the retainer and the check valve subassembly is held in the other end. In an alternative embodiment, the check valve subassembly is positioned on the interior of the porous metal flashback arrestor. Each flashback assembly can be easily removed and replaced during periodic reconditioning of the torch. The flashback assemblies utilize a parts-in-place principle which precludes operation of the torch unless both flashback assemblies are installed in the torch handle. The porous metal flashback arrestor is designed to reduce the possibility of migration of a flashback upstream from the torch.

Abstract: A sealed gas surface burner having a ring portion that sits on the main top around the periphery of the main top aperture through which the burner extends. The ring portion forms a substantially liquid tight seal with the main top, and has a raised shoulder to prevent liquid on the main top from running down through the burner aperture in the main top. A burner body is supported by the ring portion at spaced intervals to provide passageways from underneath the main top. A cap is supported by the burner body thereby forming a chamber which receives a mixture of gaseous fuel and primary combustion air. The mixture issues from ports in the side wall of the burner body where it is ignited to produce a cooking flame. Secondary combustion air is drawn from underneath the main top through the passageways in the burner to support combustion of the flame.

Abstract: A solar collector venting system comprising a lower frame member with vents which allow the entrance of cooling air when high collector stagnation temperatures occur communicating with the natural downward thermal bowing of a two walled plastic glazing caused by differences in coefficients of expansion between the cooler upper layer and the hotter inner layer of plastic glazing communicating with an upper frame member with stationary fulcrum points communicating with vents in between the fulcrums points which, upon bowing of the glazing cause the upper end of the glazing sheet to lift up off the top frame member allowing an open path for the flow of cooling air to pass up thru the collector between the absorber and the plastic glazing whose path may be kept clear by communicating with flow path spacers on the absorber.

Abstract: A radiant energy redirecting system comprising a radiant energy transmitting body structure; the structure comprising multiple elements, each of which acts as a radiant energy redirecting module, having on its cross-sectional perimeter an entry face to receive incidence of the energy into the interior of the perimeter, an exit face to pass the energy to the exterior of the perimeter in a direction towards the reverse side of the body from the side of the incidence, and a Totally Internally Reflecting face angled relative to the entry and exit faces to redirect towards the exit face the radiant energy incident from the entry face; the body structure generally redirecting incident radiant energy towards a predetermined target zone situated apart from and on the reverse side of the body relative to the side of the incidence; and lens structure associated with at least one of the faces for redirecting radiant energy passing between the entry and exit faces via the Totally Internally Reflecting face.

Abstract: A gas lighter with a child-proof safety device which can reduce wasteful evolution of gas. The lighter is provided with a flick-up type cap which closes and opens the upper part of a lighter body, an operating grip which obliquely projects out of a lateral surface of the lighter body in response to the opening action of the cap, and a linkage means for causing gas to be evolved in connection with a depression of the operating grip. Ignition of the lighter can be carried out by igniting operations of the operating grip while the cap is opened.

Abstract: In a gas-fired stove or oven, gas is burned in a porous ceramic surface combustion burner which generates selective emissive radiation in a narrow band. The high temperature surface of the burner includes a narrow band quantum emitting substance such as rare earth metal oxide. Relatively shorter wavelength radiation from this quantum emitting surface illuminates process targets having an absorption spectrum nearly matched to the emission spectrum of the burner surface, for a variety of applications such as cooking. The selected emission may be passed through a glass top stove to heat a pot with an absorptive bottom or may pass on through a glass pot to heat the food directly.

The back warmer comprises a flexible pad including an upper panel extending between opposite sides of a person and around a person's lumbar, together with a lower panel extending downwardly from the upper panel to substantially cover a person's tail bone. A belt is formed by a pair of elongate elastic straps attached to opposite sides of the upper panel and extending around a person's waist. The upper panel may also include a pocket for containing a heating element. The back warmer may also include a removable seat cushion extending downwardly from the lower panel which is hinged to the lower panel for use as a stadium cushion or the like.

Abstract: A method and apparatus for heating or cooling a product which includes a plurality of tapered ducts in a cabinet above and below a turntable to form streams which are directed toward the product. Spent air is drawn through intake openings in return ducts in the cabinet. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a product is loaded on the turntable in a loading zone to cause most of the heated air to be drawn to return duct openings and to maintain internal pressure in the baking zone in the cabinet to prevent ingress and egress of air through the loading opening. Orifices are formed in a circular array of rings such that the sum of the areas of orifices in each ring spaced from the axis about which the turntable rotates is substantially equal.

Abstract: An apparatus is provided for controlling the flow of gas for artificial logs. The apparatus includes a main gas burner and a pilot as well as a gas valve which controls the flow of gas to the main burner and to the pilot. The pilot includes a oxygen depletion sensor. A thermal responsive electrical generator is adjacent to the pilot and is connected to the valve. The output voltage of the generator is at least 250 millivolts so as to operate the gas valve, which is capable of full automatic operation without the use of an additional electrical source. In addition, the thermal responsive electrical generator is positioned with respect to the pilot so that gas from the pilot will not continue to burn about the generator when the oxygen depletion sensor senses a predetermined low level of oxygen.
