Notes To Financial Statements [Abstract]
Schedule of Subsequent Events [Text Block]	Subsequent Events We have evaluated subsequent events through the date the financial statements were filed with the SEC, noting no events that require adjustment of, or disclosure in, the consolidated financial statements for the period ended September 30, 2012, except for the matters noted below. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in our 2012 Annual Report on Form 10-K dated May 29, 2012. On October 12, 2012, our credit facility was amended to increase the total commitment amount from $300 million to $400 million. On October 16, 2012, we purchased, in an all cash transaction, two privately-owned businesses: Spectrum Surgical Instruments Corp (Spectrum) and Total Repair Express (TRE), leading providers of surgical instrument repair services and instrument care products to hospitals and surgery centers in the United States. The purchase price of approximately $110 million including contingent consideration, was financed with borrowings under the existing credit facility. These two businesses will be integrated into the Healthcare segment as part of the Healthcare Specialty Service business, which provides a variety of niche services to Customers, including space decontamination solutions, chamber cleanings and instrument repairs.

Tabular disclosure of significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, losses resulting from fire or flood, losses on receivables, significant realized and unrealized gains and losses that result from changes in quoted market prices of securities, declines in market prices of inventory, changes in authorized or issued debt (SEC), significant foreign exchange rate changes, substantial loans to insiders or affiliates, significant long-term investments, and substantial dividends not in the ordinary course of business.
