Biographical Note

Bruce A. Bydal (1937-) worked as a research engineer at the DuPont Company for over twenty years, is an expert in gun primers and chemicals, and an avid gun collector. He also worked with the Remington Arms Company, a subsidiary of the DuPont Company, to develop a new shotgun.

Bydal received his bachelor's degree in chemical engineering from the University of Illinois, Urbana, and his graduate degree in chemical engineering from the University of Minnesota.

Bydal began working with the DuPont Company in 1963; he was assigned to the DuPont plant in Martinsville, Virginia. There, he researched and experimented with various food processes, including desiccation, distillation, and salt purification. However, the principal product of the Martinsville plant was Nylon, and soon, because of his background in chemistry and applied mathematics, Bydal was charged with research and experimentation to improve the tools for the production of Nylon. During his work at the Martinsville Plant, Bydal received three patents for his contribution of tools in the process of making Nylon.

He was transferred to the DuPont Experimental Station in Wilmington, Delaware, in the 1980s. In August 1984, Bydal was invited to a meeting to by Remington Arms, a gun manufacturing company acquired by DuPont during the great depression. The meeting was to discuss concepts about a new generation autoloading shotgun. Bydal was happily assigned to the task. His lifelong hobby was collecting unique and celebrated firearms. His collection of firearms and ammunition at one time numbered nearly 800 pieces.

However, as the DuPont Company continued to focus on its chemicals and biomaterials research, the company sold off Remington Arms' assets in 1993. At this point, Bydal was nearing the end of his career with DuPont and ultimately returned to researching Nylon before his retirement in 2001.

Arrangement

The records are arranged by subjects of the laboratory notes.

Scope and Contents

The papers include descriptions of Bydal's work in DuPont's food and packaging division and his work at the Nylon plant in Martinsville, Virginia. However, approximately one-half of the records pertaining to his work in applied mathematics at Remington Arms, a gun manufacturing company acquired by DuPont during the great depression.

The collection has been arranged into fifteen series: Research - foods and nylon; Elasticity, springs, stress; New concept guns; Gas guns; Primers; Cams; Rotary bolt head; Locking; Ballistics; Mathematical modeling; Differential equation; Subject files; Computer Generated Laboratory notes; ABAQUS software; and MARC software.

Research - foods and nylon series includes his handwritten notes and weekly summaries of his work in Martinsville. Bydal participated in the First North American Symposium on Chemical Reaction Engineering in September 2000. He experimented extensively with the flow of liquid and gas substances; his poster explaining the modeling of a Two-Phase Laminar Flow Reactor and a Two-Phase Reacting Boundary Layer was lauded by his peers and documented with correspondence. The reactor was invented to monitor a substance as it is forced into a tubular device and analyzed after its exit from the tube. A common experiment is forcing methane through a tube and noting whether it has changed to a form of higher hydrocarbon.

Bydal's lab work between 1969 and 1972 earned him three patents - one for inventing a flow inverter in a transfer pipe to equalize the flow rate of a viscous material and two - second, an apparatus for dividing flow so it divides and flows into a number of sectors, each of equal weight. A third patent was granted for a mixer for a melt spinning apparatus that distributes polymers to spinning packs. All three patents were awarded to him for his work with Nylon in Martinsville.

Elasticity, springs, stress series documents his use of several sources of software to facilitate his experiments. ABAQUS, MARC, CUBE, and ADKINS provide software that can analyze, simulate, and model physical, chemical, and structural problems, providing two or three-dimensional solutions. The software can provide computer-aided solutions to engineering problems. They can even test substances for strain, stress, and elasticity.

New concept guns series consists of notes and reports that demonstrate his involvement with the design while working at Remington Arms on the design of a new concept autoloading shotgun. The papers describe in detail Bydal's daily work on the design of the new gun, as well as other types of guns in which he was interested. The papers include detailed sketches of not only the finished product but also all of the parts of the guns that were tested.

Gas guns series includes notes, drawings, sketches, and summaries about the gas gun that used gas as a propellant rather than powder or other propellant.

Primers series consists of notes and papers about small arms primers and primer setbacks. Primers are chemicals or other devices responsible for initiating the propellant. To provide the combustion that will push the projectile out of the gun barrel.

Cam series consists of notes and drawings of cams in guns. A cam in a gun that rotates or slides in a linkage is used to transfer a rotary motion to a linear motion. It might go up and down, causing an attached piece to move horizontally.

Rotary bolt head series is comprised of notes and drawings of rotary bold heads. A rotary bolt head is a device that rotates to allow a propellant into a chamber, turns around to eject a casing, and then turns to allow the next propellant.

Locking series consists of notes and drawings related to locking blocks and breech locks. When a locking block is in position, it creates a straight-line chamber from which a cartridge can be fired. After a cartridge has been fired, the lock drops down, creating space for the slide to chamber the next round. A breech lock is a way to slow down the opening of the breech of a self-reloading firearm when fired. The lock confines a high-pressure gas to the barrel, allowing the gas to expand and push the propellant out of the barrel.

Ballistics series includes several reports about internal ballistics. Internal ballistics is the study of the propulsion of a projectile until it leaves the barrel. External ballistics is the study of the projectile from when it leaves the barrel until propulsion stops.

Mathematical modeling series consists of reports, notes, surveys, and conference materials related to Nylon, the two-phase model, and other concepts related to firearms.

Differential equation series is comprised of Bydal's differential equation files, which state a function (usually a physical quantity) on one side of the equation and certain derivatives of the function (rates of change of the function) on the other side of the equation and defines the relationship between the function and its derivatives. There are also files related to the Universal Automatic Computer (UNIVAC) computer.

Subject files series includes scientific articles by various authors, drawings, notes, correspondence, and artifacts. There are gun patents by other scientists and information about various software.

The Computer Generated Laboratory notes series is comprised of files related to his work with Remington Arms on a new concept shotgun, Bydal describes research on blowback guns, blowforward guns, electronic guns, gas guns, locked Heckler and Koch (H&K) guns, rotating barrel guns, and rotating bolt guns. Heckler and Koch is a German defense manufacturing company that produces various types of handguns and rifles.

ABAQUS software was marketed in 1978 boasting five core software products: (1) computer aided engineering (2) finite element analysis (breaking a large problem down to simpler problems) (3) special finite analysis for solving nonlinear problems (4) computational fluid dynamics software and (5) solutions for electromagetic problems.

MARC software series consists of an introductory course, tutorial, and software user manuals. The MARC software provided solutions to IT staffing, all business problems, technology consultation, project management and support, and simulation of business processes.
