Title: Innovations by Jeffery R Brener

Introduction

Jeffery R Brener is a notable inventor based in Lexington, KY (US). He has made significant contributions to the field of electrical contact materials, holding a total of 5 patents. His work primarily focuses on enhancing the performance and cost-effectiveness of flexible doctor blades used in various applications.

Latest Patents

One of his latest patents is for an electrical contact material for flexible doctor blades. This invention involves a conductive paste that comprises a flexible elastomer and an electrically conductive particulate material, with the option of including a solvent. The paste is designed to provide flexible, electrically conductive bonding between materials. In a preferred embodiment, this conductive paste is utilized in a flexible doctor blade to establish bonding and an electrical connection between the support member and the blade portion that contacts the developer roller.

Another significant patent is for an abrasive shim compliant doctor blade. This invention features a compliant doctor blade that includes a metal bar attached to a resilient layer of porous foam using dual side adhesive tape. The foam layer is further attached to a shim that is stiff in the direction of movement of the roller it contacts. The shim consists of a polyester body and a bottom layer containing abrasive grit and conductive carbon black. The end of the doctor blade is dipped in a conductive paste that hardens into a conductive coating, bridging the conductive layer of the shim and the metal bar. This innovation offers advantages such as reduced costs and improved performance, particularly in minimizing streaks from prenip packing.
