Title: Innovations of William A Fischer
Introduction
William A Fischer is a notable inventor based in Denver, CO. He has made significant contributions to the field of technology with his innovative inventions. With a total of 2 patents, Fischer has developed solutions that address specific challenges in various industries.
Latest Patents
Fischer's latest patents include an ammonia absorber and a two-step solid-state battery charger. The ammonia absorber is an apparatus designed to scrub or remove ammonia fumes by passing ammonia vapor through a shower of ammonia-absorbent liquid, such as water. This invention allows ammonia vapors to be absorbed and enter into solution with the liquid, resulting in clean air being discharged into the atmosphere. The solution of ammonia and liquid is then disposed of appropriately, with a portion recirculated to absorb additional ammonia. The apparatus features a cabinet, air transfer means, a shower chamber, and a control mechanism to maintain absorbent liquid within the system.
The two-step solid-state battery charger is an electronic circuitry designed to charge batteries at a relatively high rate. It includes a semiconductor switching means, such as a transistor, and control circuitry that triggers a shunting controlled rectifier into conduction when the battery is nearly fully charged. This design prevents overcharging while providing a lower rate, trickle maintenance charge through a resistor shunt across the switching means.
