The method further includes moving the sheets in a horizontal row (18) in which the sheets are oriented vertically. The horizontal row is substantially enclosed by a second set of heating elements(22). The method further includes moving the sheets in a second vertical column (20) in which the sheets are vertically oriented. The second vertical column (20) is substantially enclosed by a third set of heating elements (22). An transport apparatus (28) for moving the sheets (12) through the vertical and horizontal passages (16,18,20) is also provided.
Abstract:
The invention relates to a heat exchanger (1) for an annealing furnace for exchanging heat between two fluids, having a tubular profile, which comprises heat exchanger ribs on the outer shell thereof and which on at least one end face (3) is associated with a connecting flange (4) having at least one flow opening (8) for one of the two fluids, particularly a hot gas. In order to create advantageous design conditions, according to the invention the profile is a profile tube made of a folded metal sheet, the heat exchanger ribs (7) of which oriented in the profile tube longitudinal direction are formed by the undulated profile, particularly by the undulation flanks, of the folded metal sheet.
Abstract:
A T-junction microwave applicator and a method for making a T-junction microwave applicator with a microwave source supplying electromagnetic energy through a junction arm to a pair of collinear arms extending in opposite directions from their junction with the junction arm. The two collinear arms form a main waveguide terminated in end walls in which entrance and exit ports are formed for a conveyor to convey material to be heated through the main waveguide for exposure to electromagnetic energy. A rectangular conductive ridge in the wall of the main waveguide opposite the junction arm extends the length of the applicator. A cylindrical tuning bar spanning the junction is positioned vertically in a plane perpendicular to the axis of the main waveguide to maximize power transfer to the material to be heated.

A portable heater/cooler system comprises a thermal electric module conducting a current through the module; a heater/cooler cavity coupled to the thermal electric module; a variable speed fan for blowing air over the thermal electric module and into the cavity; a first temperature sensor coupled to the thermal electric module for measuring the temperature of the module; a second temperature sensor coupled to the heater/cooler cavity for measuring the temperature in the cavity; and a microprocessor for adjusting a speed of the fan and the current flow through the thermal electric module as a function of the measured temperatures of the thermal electric module and the cavity.
Abstract:
The magnesium melting furnace (1) has a plurality of chambers. The material to be melted is fed into a melting chamber (2) through a charging chute (20) that dips under the surface of the melting bath. The melt is slowly transferred into a holding chamber (4) through a passage (3) situated in the lower third of a dividing wall (11) above a layer of impurities settling at the bottom (14) of the melting chamber (2). The melt flows slowly through the holding chamber (4), with impurities rising to the surface or settling to the bottom (15). The purified melt flows through a second passage (5) situated in the lower third of a second dividing wall (12) into a metering chamber (6). The melt can be removed from the metering chamber (6) through a transfer pipe (28) using a metering pump (27). The magnesium melting furnace makes it possible simultaneously to melt, purify and remove the magnesium in metered quantities.
Abstract:
In applying infrared heating to a mass production process of car body components, it is desirable that reduction in the temperature elevating time is compatible to energy saving and that an infrared furnace is simplified in structure. The infrared furnace includes a plurality of infrared lamps arrayed on one surface side of a work and a reflective surface provided on its opposite surface side. Outputs of the infrared lamps are locally adjusted, or intensity of the infrared rays incident on one work surface is locally adjusted by a member disposed between the infrared lamps and the one surface of the work. In this manner, variations in strength may be imparted to one and the same car part.
