Sail-Equipped Motorship (continued from page 26) during the second stage of the development process. Fortunately, a prototype of a sail-equipped motorship for which various experiments are sched- uled and on which high expecta- tions are placed is planned for completion during 1980. Gems Level Switches Meet Latest Self-Checking Capability Requirements Many hazardous cargoes now require self-checking of loading and off-loading operations under closed-loading conditions for crude and fuel oil, chemical, and other product carriers. The Gems LS-55555 Series manual check level switches were designed to meet these requirements, specif- ically for high level control use in closed-loading tankers, but they are equally suitable for use in other types of level applications. A unique safety feature of the LS-55555 switches is the hand simulation for pre-checking closed tank high level alarms. A simple handring atop the unit on deck raises float (s) inside the tank, just as liquid level would, to ac- tuate the system. As normal op- eration is simulated, the check is a positive one. ..... v—> '1 gjPv - wmm- v Above: The MARIE TILTON. a 396-foot long tank barge owned by Turecamo Tankers. Inc.
