Thibodaux Boiler Works Appoints Charles White Charles F. White Jr. Charles F. (Charlie) White Jr. has joined Thibodaux Boiler Works of Thibodaux, La., in materials handling equipment sales. He will be in charge of sales in the Gulf Coast area for a new line of pneu- matic tanks now in production by Thibodaux Boiler Works. These pneumatic tanks are specifically de- signed for handling drilling mud and cement materials for the drill- ing industry. A native of Louisiana, Mr. White served in a similar capacity with Perry Shankle Company of San Antonio before joining Thibodaux Boiler Works, Inc. From 1957 to 1968, he was sales manager of ma- terials handling equipment for Del- ta Southern, Baton Rouge, La. New Sensing Device For Flume Stabilization Flume Stabilization Systems, Inc. of New Jersey, has announced its second generation of ship roll stabili- zers. In addition to designing and marketing their patented passive sta- bilizers, the New Jersey corporation has expanded the line of designs to now include a full range of stabiliza- tion equipment—from fin stabilizers to the new automated tuning system for passive tanks. The primary purpose of this tuning system is to insure that the Flume tank liquid is at the proper level for maximum stabilizer performance at all times. This feature is important, since ship's personnel are thus re- lieved from the necessity of calculat- ing the vessel's stability and checking the liquid level during the voyage in order to maintain the maximum roll reduction. To achieve this, the ship's roll mo- tion and the movement of the liquid within the stabilizer are analyzed, compared, and the phase relation de- termined. The bridge console display system indicates whether the tank is performing at its peak efficiency or if liquid should be added or removed. After extensive laboratory testing and prototype test in an existing Flume tank installation, the system is now in production for standard installa- tions.
