Abstract
Abstract A temperature control system for an oven for heating and curing a powdered coating of a heat hardenable resinous material that has been applied to coil windings of a magnetic core, including a heating panel on each of two opposite sides of a core, the panels being movably mounted on an oven frame for placement of the panels at suitable distances from the core, the panels having a plurality of infrared radiation lamps adapted to be turned on and off for predetermined portions of the preheating and curing periods, an infrared radiation thermometer mounted on each panel for detecting the temperature of a selected portion of the coating and for controlling the on and off status of the lamps, and the thermometers being pivotally mounted in the corresponding panel for enabling direction of the thermometer to the selected portion of the coating.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
In an oven for curing a coating of a powdered heat hardenable resin material on a coil winding of a magnetic core located within the oven, which oven includes a heating panel of infrared radiant energy on two opposite sides of the magnetic core, and the panels being movably mounted on a supporting frame to varying positions from a magnetic core, the improvement comprising means for measuring the temperature of the resinous coating and for controlling the on and off time intervals of the heating panels during the preheat and curing periods of the coating, and the measuring means being adjustably mounted in the heating panels so that it may be directed at a selected area of the coating for temperature measurement thereof.
Claim 2
Dependent Claim
123 words
In an oven for curing a coating of a powdered heat hardenable resin material on a coil winding of a magnetic core located within the oven, which oven includes a heating panel of infrared radiant energy on two opposite sides of the magnetic core, and the panels being movably mounted on a supporting frame to varying positions from a magnetic core, the improvement comprising means for measuring the temperature of the resinous coating and for controlling the on and off time intervals of the heating panels during the preheat and curing periods of the coating, and the measuring means being adjustably mounted in the heating panels so that it may be directed at a selected area of the coating for temperature measurement thereof.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein the measuring means includes an adjustable ball and socket joint in the heating panels, for mounting the means in place.
Claim 4
Dependent Claim
17 words
The apparatus of claim 2 wherein the measuring means includes infrared radiation thermometers at each heating panel.
Claim 5
Dependent Claim
55 words
The apparatus of claim 3 wherein each infrared thermometer is mounted at one end of the tube directable at the selected area of the coating, and the ball of the ball and socket joint is attached to the other end of the tube, and the ball having an opening therethrough aligned with the tube interior.
Claim 6
Dependent Claim
61 words
The oven of claim 1 wherein the source of radiant heat energy is provided on at least two sides of the support means and are mounted on panels that are movable to and from support means, and the radiation thermometers are infrared radiation thermometers mounted in the panels and adapted for controlling the current to the source of radiant heat energy.
