Apparatus for measuring the softening point of a solid
Abstract
Abstract THIS INVENTION RELATES TO APPARATUS FOR DETERMINING THE SOFTENING POINT OF A SOLID, SUCH AS ELECTRODE BINDER PITCH OR THE LIKE. THIS APPARATUS FOR DETERMINING THE SOFTENING POINT OF A SOLID SAMPLE HAS A FIRST HEATING MEANS AND A SECOND HEATING MEANS, EACH FOR CONTAINING A SOLID SAMPLE AND FOR HEATING THE SOLID SAMPLE TO ITS SOFTENING POINT TO A PREDETERMINED UNIFORM RATE OF TEMPERATURE RISE AND HAVING SENSING MEANS FOR CONTINUOUSLY MEASURING THE TEMPERATURE WITHIN THE FIRST HEATING MEANS AND THE SECOND HEATING MEANS DURING THE HEATING OF THE SOLID SAMPLE. SWITCH GEAR MEANS AND CONNECTED TO THE FIRST HEATING MEANS AND THE SECOND HEATING MEANS TO ALTERNATELY CONNECT THE FIRST HEATING MEANS AND THEN THE SECOND HEATING MEANS TO THE APPARATUS. TEMPERATURE CONTROL MEANS ARE CONNECTED TO THE SWITCH GEAR MEANS FOR CONTROLLING THE UNIFORM RATE OF TEMPERATURE RISE IN THE FIRST HEATING MEANS AND IN THE SECOND HEATING MEANS, AND TEMPERATURE RECORDING MEANS ARE CONNECTED TO THE TEMPERATURE CONTROL MEANS AND THE SWITCH GEAR MEANS FOR RECORDING THE TEMPERATURE RISE IN THE SOLID SAMPLE AND THE SOFTENING POINT OF THE SOLID SAMPLE.
