| titleOfInvention | Epoxy resin gel tester |
| abstract | A method of and apparatus for determining the gel point of a sample of epoxy resin. An aluminum foil tube containing the sample is inserted into the test pressure sensor which is located within a preheated laboratory environmental chamber. The test pressure sensor consists of two knurled cylinders each rotatably mounted about its axis wherein the axes are parallel and the plane of the two axes is horizontal. The axis of one of the cylinders is fixedly mounted. The axis of the other cylinder is slidably mounted within the horizontal plane of the two axes. A spring tends to force the axis of the slidably mounted cylinder toward the axis of the fixedly mounted cylinder. The sample becomes liquid within the tube, and the two are drawn into the nip of the cylinders by their rotation. The cylinders continue to rotate collapsing the sample tube within the nip of the cylinders causing the liquid resin to be displaced above the nip of the cylinders within the sample tube. When the sample becomes a plastic wedge, signifying the gel point, it is drawn into the nip of the cylinders forcing them sufficiently apart to be measured by a set of electric contacts. A timer records the number of seconds between the insertion of the sample and the gel point. |
