Title: Steven C. Lawver: Innovator in Composite Manufacturing and Powder Delivery Systems

Introduction

Steven C. Lawver, an accomplished inventor based in Sterling, VA, is known for his significant contributions to the field of manufacturing technologies. With a total of three patents to his name, Lawver has demonstrated a commitment to advancing modern engineering practices, particularly in projectile manufacturing and powder delivery systems.

Latest Patents

One of Lawver's latest patents is titled "Method of manufacturing composite projectile body embedded with preformed fragments." This innovative method focuses on the preparation of a composite projectile body that incorporates preformed fragments seamlessly embedded within its walls. The technique utilizes a combination of additive manufacturing and advanced powder metallurgy fabrication. Key to this process is the creation of a skeletal structure or prefabricated cage body, which is filled with these preformed fragments. This cage is situated on a mandrel inside a container filled with metal powder, which undergoes degassing under vacuum and sealing. Following this, the container is exposed to heat and pressure to consolidate the powder into a full-density form. After removal, the compacted billet undergoes further machining to refine the final projectile body.

Another notable patent from Lawver is the "Fluidized powder valve system." This device revolutionizes the controlled and precise delivery of powders, including cohesive powders, through a fluidization technique. By significantly reducing inter-particle friction with a fluidizing gas acting as an air-bearing, this system boasts no moving parts, sealing gaskets, or sealing surfaces. Unlike traditional mechanically actuated valves, the powders dispensed via this device avoid mechanical shearing, resulting in reduced wear and an extended service life of the apparatus.
