Abstract: An improved thermal oxidizer (10) comprising a combustion chamber (62), a refractory coated mixing device (14) within a plenum (12), a burner (26) mounted outside the oxidizer (10) for ready access, and temperature sensing and control equipment (86). The oxidizer (10) uses the mixing device (14) to induce a static pressure drop between the burner (26) and the oxidizer inlet (16), and a flow passage conveys preheated gas from the plenum (12) to the burner (26). A bend in the combustion chamber (92) provides for recirculation of combustion gases for more efficient burning. The burner (26) can be a commercially available unit that can accommodate inlet temperatures of up to 1200° F., allowing efficient operation of the thermal oxidizer (10).

Abstract: This artificial fish bait embodies five attractants in a body with a dynamic tail to lure the fish. The attractants embodied in the bait are noise, light, taste, smell, and color. The effectiveness of each attractant is enhanced by undulating movement of the tail through the water.

Abstract: A thermocouple rake for measuring the temperature of heated fluids. The thermocouple rake is provided with a cooling chamber for circulating a coolant about individual thermocouple assemblies to cool the assemblies during use in the hot gas. A U-shaped channel is formed downstream in the flow of fluid to accept lead wires from the thermocouple assemblies to deflect the hot gas fluid from contacting the lead wires.
