Title: **John David Webster: Innovator in Fluid Pumping and Pipe Lining Solutions**

Introduction

John David Webster, an accomplished inventor based in St. Austell, GB, has made significant contributions to the fields of fluid dynamics and material application. With a remarkable portfolio of five patents, Webster's innovations focus on enhancing the efficacy and efficiency of pumping systems and pipe lining techniques. His latest patents exemplify his dedication to solving complex engineering challenges.

Latest Patents

One of Webster's latest patents describes a **System for pumping an abrasive or corrosive fluid**. This system operates at high pressure and features a variable delivery rate. It involves raising the pressure of a non-corrosive and non-abrasive liquid using a specialized pumping mechanism and two intermediate cylinders fitted with floating pistons. The resultant high pressure is then applied to an abrasive or corrosive fluid through designated pressure transfer vessels. A carefully engineered valve arrangement manages the flow of liquid into the intermediate cylinders while allowing for the return of floating pistons after each stroke. This system is particularly advantageous for applications such as supplying clay slurry to high-pressure plate filter presses.

Another notable invention is a **Method of lining pipes, molds, or other tubular articles with settable material**. This innovative method entails arranging a pipe with its longitudinal axis inclined, introducing liquid material at a controlled rate to allow it to flow down the pipe, and subsequently shifting the pipe to a horizontal position for material distribution. The spinning of the pipe continues until the material has set, making this method especially effective for lining pipes with polyurethane. Additionally, for pipes equipped with end flanges, the end faces of the lining can be formed as an integral part of the lining material.
