Subsequent Events [Abstract]
Subsequent Events	19) Subsequent Events In April 2017, the Company completed the sale of its Data Analytics Solutions business for approximately $80,000 and expects to record a pre-tax gain of approximately $75,000, during the second quarter of 2017. This business, which had net revenues in 2016 of $12,700 and was included in the Vacuum & Analysis segment, was no longer a part of the Company’s long-term strategic objectives. The business did not qualify as a discontinued operation as this sale did not represent a strategic shift in the Company’s business, nor did the sale have a major effect on the Company’s operations, therefore, the results of operations for all periods are included in the Company’s income from operations. The assets and liabilities of this business have not been reclassified or segregated in the consolidated balance sheet or consolidated statements of cash flows due to the immaterial amounts.
