TRIESTE REVISED 



When the Navy's deep-diving Bathyscaphe Trieete 

 makes its next descent to the ocean floor, it will 

 be equipped with a mechanical arm that can reach out 

 and pick up samples of material frcm the inysterious 

 and little— known depths, some even seven ndles belwr 

 the surface, A General '-fl-lls mechanical arm mani- 

 pulator adapted to withstand the tremendous pressvrcs 

 of 8—9 tons per square inch encountered at the deepest 

 parts of the ocean, will provide this unique capabili- 

 ty. The Trieste "arm" will be modified by means of 

 special oil-filled units designed to equalize pres- 

 sures on motors and other critical parts, Ooeanog- 

 raphers riding in the steel ball suspended beneath 

 the Trieste will control the device by means of a 

 compact control box with individual lever action 

 switches to provide direction and continuously 

 variable speeds for each of six motions. The 

 Trieste program is under the joint sponsorship of 

 the Bureau of Ships end the Office of Naval Research,
