A system and method for developing a heat treatment process using a model radiative-heating oven, which repeatably and accurately simulates an industrial heat treatment system. In order to simulate the industrial heat treatment system, the model radiative-heating oven uses a variety of scaling factors, such as heating density parameters. The model radiative-heating oven also may have a quickly openable and closable object carrier, which facilitates a timely start and end of a desired heat treatment process. An oven temperature stabilizer also may be provided for thermally stabilizing the model radiative-heating oven prior to the desired heat treatment process. The present technique also may utilize a variety of heat profile controls, such as time, temperature, and power levels, to provide the desired heat profile in the heat treatment process.

A dual knife-edge transfer conveyor for transporting small articles from one conveyor to a second conveyor, upper sections of the conveyors being in approximately the same plane, the conveyors being driven in the same transport direction and following each other immediately in the transport direction and thus forming a gap between the two conveyors, the dual knife-edge transfer conveyor comprising: a dual knife-edge plate member, an endless transfer belt, the transfer belt revolving about the dual knife-edge plate member, a transfer conveyor frame, the dual knife-edge plate member being attached to an upper section of the frame, the dual knife-edge plate member also having a pair of edges, each of the edges having a small radius, the frame being positioned in between the two conveyors such that the dual knife-edge plate member lies in approximately the same plane as the two conveyors, the dual knife-edge plate member further having a length slightly smaller than the gap formed between the two conveyors, deflection rollers, the deflection rollers being attached to the frame below the dual knife-edge plate member for deflecting the transfer belt around the edges of the dual knife-edge plate member inwardly and away from the two conveyors at an angle less than 90 degrees to enable the transfer belt to snugly fit within the gap created by the two conveyors without the transfer belt touching the two conveyors, and a drive for driving the transfer belt in the same transport direction as the two conveyors.

An apparatus for heat treating the surface of a body includes an infrared heat source carried on a stand. A circuit controls the energization of the lamp. The circuit includes a heat detector for detecting a targeted area temperature. The apparatus includes a sighting mechanism to permit an operator to accurately sight the heat detector against the surface to be heat treated.
