Accounting Policies [Abstract]

Nature of Operations [Text Block]

Nature of Operations: The Company is a leading global manufacturer of standard and custom-engineered products and systems serving a wide variety of low-temperature and cryogenic applications. The Company has developed an expertise in medical respiratory equipment and cryogenic systems and equipment, which operate at low temperatures sometimes approaching absolute zero. The majority of the Company’s products, including vacuum insulated containment vessels, heat exchangers, cold boxes and other cryogenic components, are used throughout the liquid-gas supply chain for the purification, liquefaction, distribution, storage and end-use of industrial gases and hydrocarbons. The Company has domestic operations located across the United States, including principal executive offices located in Ohio, and an international presence in Asia, Australia and Europe.

Principles of Consolidation

Principles of Consolidation: The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Investments in affiliates where the Company’s ownership is between 20 percent and 50 percent, or where the Company does not have control, but has the ability to exercise significant influence over operations or financial policy, are accounted for under the equity method.

Use of Estimates

Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They may also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

Reclassification, Policy [Policy Text Block]

Reclassifications: Certain reclassifications have been made to the 2012 condensed consolidated statement of income and comprehensive income and 2012 condensed consolidated statement of cash flows in order to conform to the 2013 presentation.

Derivatives, Policy [Policy Text Block]

Derivative Instruments: The Company utilizes certain derivative financial instruments to enhance its ability to manage foreign currency risk that exists as part of ongoing business operations. Derivative instruments are entered into for periods consistent with related underlying exposures and do not constitute positions independent of those exposures. The Company does not enter into contracts for speculative purposes, nor is it a party to any leveraged derivative instrument. The Company is exposed to foreign currency exchange risk as a result of transactions in currencies other than the functional currency of certain subsidiaries. The Company utilizes foreign currency forward purchase and sale contracts to manage the volatility associated with foreign currency purchases and certain intercompany transactions in the normal course of business. Contracts typically have maturities of less than one year. Principal currencies include the euro, the British pound, the Czech koruna, the Australian dollar, the Norwegian krone, and the Chinese yuan. The Company’s foreign currency forward contracts do not qualify as hedges as defined by accounting guidance. Foreign currency forward contracts are measured at fair value, which is based on valuations provided by the transaction counterparties, and recorded on the condensed consolidated balance sheets as other current liabilities or assets. Changes in their fair value are recorded in the condensed consolidated statements of income and comprehensive income as foreign currency gains or losses. The Company's foreign currency forward contracts are not exchange traded instruments and, accordingly, the valuation is performed using Level 2 inputs as defined in Note C. Gains or losses on settled or expired contracts are recorded in the condensed consolidated statements of income and comprehensive income as foreign currency gains or losses. The Company recorded a net loss of $598 and a net gain of $603 for the three and six months ended June 30, 2013, respectively, and net gains of $1,503 and $1,147 for the three and six months ended June 30, 2012, respectively related to derivative instruments.
