Title: Innovations by Leslie D Rikker

Introduction

Leslie D Rikker is an accomplished inventor based in Oak Forest, IL (US). She has made significant contributions to the field of engineering, particularly in the area of evaporative pattern casting. With a total of 8 patents to her name, Rikker's work showcases her innovative spirit and technical expertise.

Latest Patents

Among her latest patents is a method and apparatus for treating gaseous material from evaporative patterns. This invention involves a process where the gaseous material resulting from the evaporation of the pattern is effectively removed from within a container. The gaseous material permeates through a packed unbound molding medium, allowing for the regulation of its outflow to control the rate of displacement of the pattern by molten metal. The process also includes cleaning and cooling the removed gaseous material, resulting in the formation of condensate and detoxified gas, which are subsequently discharged.

Another notable patent by Rikker is related to a molding medium and the method for making it, specifically designed for use in the evaporative pattern casting process. This molding medium comprises a base granular molding material with spherically shaped grains, which are coated with a refractory material. The innovative process involves coating the grains with a binding agent before mixing them with a refractory material, such as zirconium oxide. The resulting product consists of substantially spherical free-flowing particles that facilitate close contact with the pattern of the object to be cast.
