Title: Seiichiro Ichikawa: Inventor in Filtration and Glass-Container Coatings

Introduction

Seiichiro Ichikawa is an inventor associated with Kawaguchi, Japan, and Sapporo Breweries Limited. His patent work addresses filtration equipment and methods for covering abrasions on glass containers. He is credited with 2 patents.

Latest Patents

Ichikawa’s listed patents include “Filtration Apparatus with Means for Preventing Peeling Off of a Pre-Coat.” The invention concerns an apparatus with upright tubular filter elements coated with a filter-aid pre-coat. A gas exhaust tube or liquid drain tube connected to the filter element allows the liquid used to form the pre-coat to be discharged before filtration begins. This helps switch to the liquid being filtered without mixing the two liquids or damaging the pre-coat layer.

His other listed patent is “Method of Covering an Abrasion of a Glass Container by Applying a …”. The described method covers an abrasion by coating the glass container with an aqueous dispersion of a coating material. The available description does not specify the complete title or all components of the coating.

Career Highlights

The listed inventions focus on practical processes relevant to filtration and glass-container treatment. The filtration apparatus is designed to preserve the pre-coat during the transition from preparation to filtration, while the glass-container method addresses the covering of surface abrasions.

Collaborations

Ichikawa’s listed coworkers include Hiroshi Kuroda and Ichiro Nakamura. His company affiliation is Sapporo Breweries Limited.

Conclusion

Seiichiro Ichikawa’s two listed patents reflect work on filtration equipment and glass-container coatings, with an emphasis on managing process transitions and treating surface damage.
