Heinz P. Bloch earned BSME and MSME (cum laude) degrees from the New Jersey Institute of Technology (1962).  After assignments in Italy, Spain, England, The Netherlands and Japan, and upon retiring from Exxon Chemicals USA as their Regional Machinery Specialist, he became Owner/Principal of Process Machinery Consulting. He has made presentations at plants and to conference attendees worldwide on machinery reliability improvement, including to audiences of the ASME, AFPM (NPRA), TAPPI, AIChE, SMRP, STLE, Texas A&M (TAMU) Turbomachinery and Pump Symposia; also to over 500 State and private companies in 43 countries in Africa, Asia, Australia, Europe and North and South America.

He is a Founding Member of TAMU’s International Pump Users Symposium and is an ASME Life Fellow. He received the American Society of Lubrication Engineers’ Wilbur Deutsch Memorial Award (1982); ASME/STS Engineer of the Year Award (1995); ASME Frederick Smarro Plant Engineering Award (1999); ASME Distinguished Service Award (2001) and holds seven US patents on high-speed machinery lubrication and component upgrading. 

Mr. Piotrowski graduated from the University of Pittsburgh in 1974 with a degree in Mechanical Engineering. He has been working with rotating machinery in industry for over 44 years and is considered to be one of the leading authorities on alignment of rotating machinery.  He has authored over fifty technical articles on the subject and is author of the Basic Shaft Alignment Workbook, the Shaft Alignment Self Study Guide, and the Shaft Alignment Handbook (now in its 3rd edition).
He was one of the contributing authors for the development of the ANSI/ASA Shaft Alignment Standards (ANSI/ASA S2.75 Parts 1, 2, and 3).  He has also a contributing author to the 4th and 5th editions of the Shock and Vibration Handbook (ISBN 0-07-026920-3, Chapter 39. Part II: Vibration Induced by Shaft Misalignment). Mr. Piotrowski is an active member of the Vibration Institute.  
Since founding Turvac Inc. in 1982, John has trained over 7500 people in shaft alignment principles and methodology, been a consultant to several major shaft alignment equipment manufacturers and participated in alignment service work in a wide variety of industries.  He has designed training demonstrators for alignment and balancing, shaft alignment measurement systems, shaft alignment software programs, invented the Ball-Rod-Tubing Connector system used to measure off-line to running machinery movement, and performed several controlled alignment / vibration tests. But above everything else, John loves what he is doing and wants everyone who is involved with rotating machinery to understand this broad and fascinating topic.

Robert graduated from Wright State University in 2019 with a Bachelor of Science Degree in Mechanical Engineering. Since graduating, Robert has been working with rotating machinery and training personnel in shaft alignment. He has also been certified in Level II Shaft Alignment. Robert is passionate about growing his knowledge of alignment and spreading what he has learned to others.
