.~ Controlling varying temperature or plural heating steps
DEFINITION
Classification: 264/29.7
(under subclass 29.1) Processes wherein the carbonizing step is carried out by (1) varying the temperature over a given time span or by (2) heating the article to two or more distinct temperatures.
(1) Note. Heating the article to cure binder or dry is not considered carbonizing unless positively disclosed that such occurs under those conditions.
(2) Note. Heating to a temperature to cause a change in crystalline form of the carbon (e.g., graphitizing) is considered a step of carbonizing for this subclass.
