Title: Innovations by John F. Blanch
Introduction
John F. Blanch is a notable inventor based in Mantoloking, NJ (US). He has made significant contributions to the field of rheology, holding a total of 2 patents. His work focuses on advanced measurement techniques that enhance the understanding of material properties.
Latest Patents
One of his latest patents involves on-line rheological measurements. This innovative method utilizes a rheometer where a first metering pump delivers diverted melt from a process main stream to a capillary passage. A second metering pump returns the diverted melt to the process main stream, allowing for precise viscosity measurements. The system maintains a constant pressure drop along the capillary passage while measuring the temperature of the melt. This design ensures a quick response to changes in viscosity by minimizing the residence time of the diverted melt outside the main stream.
Another significant patent by Blanch is a fixture for holding a bending test specimen. This test fixture is designed to measure the forces required to bend a specimen across a range of temperatures. It features clamps that grip the ends of the specimen while allowing for movement in response to temperature changes. The constant force springs maintain tension on the specimen during the measurement process, ensuring accurate results.
