Title: The Innovative Contributions of Dan R. Landis

Introduction

Dan R. Landis is a notable inventor based in Bexley, Ohio, recognized for his significant contributions to the field of gauging apparatuses. With a total of two patents to his name, Landis has developed innovative technologies that enhance the measurement of sheet materials.

Latest Patents

One of Landis's latest patents is a "Sheet measuring apparatus with two structurally isolated non-contacting." This invention is designed for measuring properties such as the caliper of a traveling sheet. It features a sensor body and a target body located on opposite sides of the sheet, constrained by gas bearings along a sensor path. These gas bearings maintain a constant distance from the sheet's surfaces while allowing movement in response to the sheet's position and thickness. The interaction between an active sensor element on the sensor body and a passive sensor element on the target body produces a response that indicates the sheet's properties. This response is detected at a location spaced from the sensor body, generating a signal indicative of the sheet's characteristics.

Another significant patent by Landis is the "Pneumatic surface follower with negative feedback of a variable force." This gauging apparatus is designed for sheet materials and includes a surface follower body that is guided for movement along a path intersecting the traveling sheet. The body discharges pressurized gas against the sheet's surface, generating a levitating force that maintains a predetermined distance from the sheet. A counteracting force responsive to the gas pressure helps maintain this distance, ensuring accurate gauging despite minor pressure variations.
