Abstract
Abstract An oven for heating and curing a powder of heat hardenable resinous material that has been applied to the portions of coil windings in a slot of a magnetic core as well as to the coil end turns including at least two heating panels disposed at spaced distances from the coated coil windings, the panels having a plurality of infrared radiant energy sources directed towards the coil windings, the panels being movable toward and away from the position of the coil windings, and control means associated with the panels for measuring the temperature of the resinous coating on the coil windings during the heating and curing operation, which means are operatively connected to the circuit of the infrared heat sources for turning the source on and off at prescribed intervals.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
86 words
An oven suitable for curing a heat-hardenable, resinous coating on coil windings in the slots of a magnetic core and for accurately and automatically controlling the temperature of said coating comprising 1. at least one infrared heating panel directed at said coating; 2. an optical radiation thermometer which measures infrared radiation and generates an electrical signal proportional to said radiation, said electrical signal automatically controlling the output of said infrared heating panel; and 3. means for directing said thermometer at a selected point on said coating.
Claim 2
Dependent Claim
86 words
An oven suitable for curing a heat-hardenable, resinous coating on coil windings in the slots of a magnetic core and for accurately and automatically controlling the temperature of said coating comprising 1. at least one infrared heating panel directed at said coating; 2. an optical radiation thermometer which measures infrared radiation and generates an electrical signal proportional to said radiation, said electrical signal automatically controlling the output of said infrared heating panel; and 3. means for directing said thermometer at a selected point on said coating.
Claim 3
Dependent Claim
30 words
an optical radiation thermometer which measures infrared radiation and generates an electrical signal proportional to said radiation, said electrical signal automatically controlling the output of said infrared heating panel; and
Claim 4
Dependent Claim
30 words
an optical radiation thermometer which measures infrared radiation and generates an electrical signal proportional to said radiation, said electrical signal automatically controlling the output of said infrared heating panel; and
Claim 5
Dependent Claim
23 words

Claim 6
Dependent Claim
12 words
means for directing said thermometer at a selected point on said coating.
Claim 7
Dependent Claim
12 words
means for directing said thermometer at a selected point on said coating.
Claim 8
Dependent Claim
42 words
