Concise 28 vs. 28N Cursors
|
Concise No.28 vs No. 28N Circular slide rules
The 8.5cm diameter No. 28 has a wrap-around double-sded cursor which served no use in carrying calculations to the other side.
The 28N has a cost-reduced single-sided cursor that has a slight lip on the end that rides in a grooved track in the face near the outer edge.
This keeps the user from catching accidently. The No.28 has a wrap-around double-sded cursor which served no use in calculations.

Donated by Michael P. Maloney
Michael P. Maloney finished pre-engineering at Niagara University in 1965 and graduated as an Electrical Engineer in 1968 from the University of Detroit. He also attended George Washington University and received a Master Degree in Engineering Management in 1978. After graduating from the University of Detroit, he joined the Department of Defense (DoD) and retired as a Technical Director in 1997. While working for the DoD, Mr. Maloney had three tours in Europe totaling 13 years. Mr. Maloney used the ten different types of slide rules or slide charts in the design, development, installation and maintenance of communication and radar systems. These have been donated to ISRM. Mike writes:
"Of particular interest to me is the shirt pocket SRL circular slide rule and my white plastic 'nerd pack' (shirt pocket protector). These two items traveled with me on all my TDYs (business trip) while stationed in Europe during the 'Cold War'." Upon retiring from the DoD Mr. Maloney worked for Raytheon, Applied Signal Technology, Conquest, Boeing and Hayden Software Consulting. Mr. Maloney has five patents and enjoys wood working, traveling, reading and developing algorithms for solving cryptograms.

Richard Levy 1932 - 2017 was born in London, and as a child, he was evacuated to Montreal to escape the Blitz during the WWII, He returned to London in 1943 to complete his schooling and graduated from Cambridge with a BA in Math. He married Midge in 1955, and then moved to the USA. He received a Fellowship at Princeton University and earned a PhD in Aeronautical Engineering. During this time he made extensive use of his slide rules. He returned to Montreal to begin his career at Canadair, and subsequently moved to Boston where he worked for AVCO during the 1960s and 1970s. At AVCO he began work on laser applications, and with Sargent Janes, coauthored a number of patents regarding their use in the separation of isotopes which has important applications in the production of nuclear energy. This accomplishment led to the formation of a joint venture between Avco and Exxon, and in 1974 he moved to Seattle to begin work with this new entity. He left corporate life in 1980, retiring in Seattle. He spent retirement consulting and studying issues such as the Allies decision not to bomb the rail lines leading to Auschwitz. He enjoyed the outdoors, the symphony and the opera, and was proud of his heritage.

Gift of Bruce Healy
Bruce writes: "I am not a slide rule expert. My father gave me my first calculator in my sixth grade (1978), and I never had to really learn the slide rule. Attempts to teach me happened, but never stuck well. My father (still) teaches EE at Santa Clara University at age 88, I graduated with a ME degree in 1987. So, although I was on the cusp of the technology change, slide rules still fascinate me.
Your ISRM web site has been a valuable resource every time I happen to find a slide rule that is in need of rescue and a new caring home. Thank you for providing such a great source of information. I would happily send you this slide rule for the lowest amount that Ebay will allow, $1.
Please continue your good work, and know that it is appreciated.
Be healthy,
Bruce."
