Title: Frank L. Slejko: Patents in Water Treatment and Polymerization Inhibition.

Introduction

Frank L. Slejko is an inventor associated with Bristol, Pennsylvania. His work includes inventions addressing bacteria removal from liquid media and the inhibition of polymerization in specialty chemical monomers. He is credited with 3 patents.

Latest Patents

One of Slejko’s described inventions, “Removal of Bacteria,” concerns an ion-exchange column designed to remove bacteria from a liquid medium. A submicron-pore filter placed downstream serves as an indicator of the column’s capacity. When the ion-exchange column becomes substantially exhausted, bacteria pass through and quickly plug the filter. The resulting pressure increase reduces the liquid flow, alerting the user that the column needs attention.

Another described invention, “Polymerization Inhibitors for N-Substituted Aminoalkyl Acrylic Monomers,” presents a method for limiting unwanted polymerization during the preparation, purification, or storage of these monomers. The method uses specified inhibitors, including nabam, maneb, zineb, mancozeb, or certain salts of tin, copper, manganese, or cobalt.

Career Highlights

Slejko’s patent work reflects an applied approach to chemical and process challenges. The bacteria-removal invention combines treatment with a practical signal for identifying when the system’s capacity has been depleted. The polymerization-inhibition method focuses on preserving monomers under ambient and higher-temperature conditions.

Collaborations

Slejko is associated with Rohm and Haas Company. James S. Clovis is identified as a coworker.

Conclusion

Frank L. Slejko’s inventions address practical needs in water treatment and chemical processing, with a focus on reliable bacteria removal and controlling polymerization.
