The Inventors Behind US1338343A
The patent was developed by Paul Weiss and Jules Verdier, two French inventors. Their collaboration aimed to create a reliable method for producing dense artificial clouds and fog. At the time, the world was grappling with industrial growth and the need for innovative solutions to environmental and operational challenges. The work of Weiss and Verdier stood out as a pioneering effort to use chemical reactions to create artificial atmospheric phenomena.
The Core Invention: Process and Apparatus
The Process
The patent describes a chemical process designed to produce dense artificial fog. The main components of this process include:
- Anhydrous Chlorides: Chemicals like titanium or stannic chloride are atomized into a moist ammoniacal atmosphere.
- Chemical Reaction: When the anhydrous chlorides are exposed to the moist, ammoniacal atmosphere, they react to form dense clouds of artificial fog or mist.
- Controlled Atomization involves atomizing chemicals to ensure uniform fog density and effectiveness.
The Apparatus
The apparatus outlined in the patent includes:
- Two Steel Flasks:
- One flask contains anhydrous chloride (e.g., titanium chloride).
- The other flask contains ammoniacal gas in a liquefied state.
- Atomizing Mechanism: The chemicals are atomized at the top of a chimney or nozzle, allowing the reaction to occur in the open air.
- Structural Design: The apparatus facilitates easy deployment and maintenance, making it suitable for industrial and outdoor applications.
