Caliper Coating Measurement on Continuous Non-Uniform Web Using THZ Sensor
ActiveUS20130204577A1Accurate and preciseEasy to measureInvestigating moving sheetsDigital computer detailsTime domainRefractive index
An analytical model simulates the propagation of radiation through a coated continuous web where layer thickness and refractive index, as variables, determine the speed and direction of transmitted radiation. The model predicts characteristics of transmitted radiation based on characteristics of incident radiation and initially assigned values for layer thicknesses. Coating thickness(s) are ascertained in a process whereby incident radiation of known characteristics is directed onto a coated web and thereafter, actual measurements of transmitted radiation are compared to predicted characteristics. Using a fitting algorithm, the assigned thickness(es) of the layer(s) of the model are adjusted and the process repeated until the actual and predicted values are within desired limits at which time, the assigned thickness(es) represent the measured calipers. Radiation measurements are obtained using terahertz time-domain spectroscopy apparatus that creates a continuous reference whereby a sample pulses' phase and amplitude can be tracked and corrected.

Bearing puller
ActiveUS7980604B2Efficient and safe mannerImprove efficiencyMetal working apparatusFastening meansFree rotationGear wheel
A novel and improved puller that provides a safe and efficient manner and tooling to remove bearings, bushings, gears, etc. The invention is simple and highly efficient is its design and use due to incorporating multiple design elements into the main collets or bearing adapters. My present invention uses a simple split collet machined accurately to precisely fit the bearing being removed, in addition the same collet incorporates an upper threaded section to allow the removal sleeve to easily and precisely fit to the collet while at the same time the threaded removal sleeve securely keeps the collet together and properly aligned with the bearing and shaft axis to provide easy and accurate operation. Another design integrated into my puller is the ball thrust bearing on the end of the pressure or removal screw. This anti-friction thrust bearing eliminates undue friction and provides very free rotation of the pressure screw.
