Case No. 43-51-6393 APPLICATION FOR LETTERS PATENT FOR INSTRUMENT AND METHOD FOR CONTROL TESTING OF VULCANIZED RUBBER ABSTRACT OF THE DISCLOSURE A curemeter has dies maintainable at a substan- tially uniform vulcanization temperature, the dies being arranged to be separable and for closure, and which when closed define a cavity for accommodating a sample of compounded rubber, means for subjecting the sample of compounded rubber to oscillating shear strain and means for obtaining a signal derived from such oscillation and correlating with the degree of vulcanization of the sample. The curemeter of the invention is characterized by also having separable dies maintainable at the same substantially uniform vulcanization temperature as the first said dies, and which when closed define at least one cavity for accommodating a further sample of the compounded rubber for vulcanization under static conditions.
