He was a self-taught engineer who will be remembered in the industry for his many inventions and developments. On leaving high school in , Norb Arnold won a scholarship to the International Correspondence School in industrial and analytical chemistry and joined Keystone Carbon Company now Keystone Powdered Metal Company as a laboratory technician.
From to , Norb served in the 4th Marine Division, fighting in the fierce battle of Iwo Jima. In the early 90s, he assisted with the design and set up of a PM laboratory at the DuBois Campus of Penn State University and the development of related continuing education courses.
When Keystone began making PM bearings in , it was difficult to measure the density of the compacted or sintered parts. After returning to Keystone in , he developed the Keystone Sampling Thief, an auger type instrument used for obtaining representative samples of metal powder product in a powder barrel or packaging container.
In , Norb developed the Arnold Density Meter. This device duplicates the action of the fill shoe on a powder compacting press and measures the apparent density of a metal powder. It is also used for measuring the volumetric flow rate and is claimed as the easiest and most practical method for these tests. A programme was initiated with Vanadium Alloy Steel Company which was interested in making prealloyed steel powder.
Norb Arnold, as Keystone's chief metallurgist, headed this project; and by , Keystone was in full production of high strength gears for the hydraulic pump industry. Norb also pioneered the introduction of turbine oils and later synthetic oils in the production of oil-impregnated PM bearings. Norb was an avid golfer. He was the St. He was also instrumental in establishing the greens at the Bavarian Hills Golf Course.
Norb was also involved in the community. He was also very active in the Catholic School System. Although proud of his service and accomplishments, he was most proud of his family.
Okay, I understand Learn more. Norbert A Arnold. Photo courtesy of the Arnold family. Prealloyed powder 1n Keystone was interested in obtaining higher mechanical properties than could be achieved with elemental powders. Family life Norb was an avid golfer.

At this time, LTI is open for normal business operations. Read our statement from president, Brandon McVaugh. Wet Chemistry , also called wet chemical analysis, generally refers to chemistry performed on samples in the liquid phase. Since wet chemistry analysis is performed on liquid samples, this type of element analysis can often be performed on samples too small for other instrumental methods. Both classical and instrumental wet chemistry services can provide qualitative and quantitative data about the elemental make-up of the test sample. Laboratory Testing Inc. Our classical wet chemistry lab performs traditional techniques such as Colorimetry, Gravimetry and Titrimetry.
