Title: Innovations of Leo H Weisman
Introduction
Leo H Weisman is an accomplished inventor based in Warren, MI (US). He has made significant contributions to the field of ultrasonic measurement technology, particularly in the context of coal flow measurement in power generation.
Latest Patents
Weisman holds 2 patents that showcase his innovative approach to measuring gas velocity and solids. His first patent involves an ultrasonic instrument designed to measure the mass flow rate of finely divided coal in large-scale fossil fuel power plants. This invention features various embodiments of transducer assemblies that enable ultrasound pulses to be transmitted across a conduit. The system evaluates the downstream drift and attenuation of these pulses, correlating them to coal concentration and velocity. In one embodiment, transducers are mounted at diametrically opposite positions, with the transmitting transducer aimed upstream and the receiving transducer aimed downstream to maximize signal output. The second embodiment utilizes linear arrays of transducers to create a steerable wave front, enhancing measurement accuracy.
His second patent focuses on a flow meter specifically adapted for measuring the mass flow rate of pulverized coal introduced into power generation boilers. This device includes a transmitter that generates pulsed ultrasonic impulses, with a receiver positioned across the flow field. The meter measures the downstream drift and attenuation of the ultrasound pulses, which relate to flow velocity and concentration. The instrument is equipped with electronic circuitry that automatically adjusts the relationship between the transmitter and receiver, performing numerical analysis to provide accurate readings of coal concentration and velocity.
