233.2.~ Specific rate of varying temperature or schedule of distinct temperatures


DEFINITION

Classification: 228/233.2

Specific rate of varying temperature or schedule of distinct temperatures:

(under subclass 101) Process (a) including applying thermal energy to the meeting faces or to the filler, to raise the thermal level (i.e., temperature) thereof, expressed in a claim in precise, numerical language with regard to the rate of change of the temperature or expressed as the rate of applying thermal energy to the work; or (b) including establishing a first temperature to the meeting faces or to the filler expressed in a claim in precise, numerical language and subsequently establishing a second, different temperature thereto, also expressed in a claim in precise, numerical language.
