Title: John H Elvidge: Innovator in Glass Flake Technology
Introduction
John H Elvidge is a notable inventor based in West Yorkshire, GB. He has made significant contributions to the field of engineering, particularly in the development of methods and apparatuses for forming glass flakes. With a total of 2 patents to his name, Elvidge's work showcases his innovative spirit and technical expertise.
Latest Patents
Elvidge's latest patents include a method and apparatus for forming glass flakes and a jet pump. The jet pump is designed for pumping liquids, gases, or particulate solids. In this innovative design, both the primary and secondary flows pass through the pump in-line, meaning they move in the same axial direction. This is accomplished by mounting the nozzle head at one end of a streamlined body, which is supported in the mixing chamber. The suction hose opens directly onto the other end of the body, allowing the primary flow to pass through the streamlined body. Consequently, the secondary flow is sucked over the streamlined body and entrained by the primary flow. The primary flow can issue from a single nozzle at the downstream end of the streamlined body, or several jets may issue from a ring of nozzles, all angled to converge downstream of the nozzle head.
