AND MMC WILL SUPPLY A CUSTOM-TAILORED SONIC PROBE MMC sonic probes are available in two configurations — fixed point and interface. A change in the density or medium activates the probe which operates on attenuation of a steady ultrasonic signal. Controllers may be housed in a wide range of enclosures — from sheet metal to explosion proof types. Every MMC sonic probe features intrinsic safety and repeatability. Also, probes are not affected by coating and are U. S. Coast Guard approved as intrinsically safe, Class I, Group D, 12 Vac Secondary from a 115V A.C. shielded primary.

The first ship is required by mid- 1975, with completion of the con- tract by the end of 1976. Apparent- ly, delivery dates are sufficiently imperative to compensate for any higher than foreign prices that may be quoted by American yards. With extended deliveries being offered abroad and foreign ship prices climbing, the U.S. shipbuild- ing industry may soon obtain its first export contract in many years. Reprieve Given To 4 M-Class Cargo Ships By Prudential-Grace It was announced by Prudential- Grace Lines in November 1970 that four M-class passenger-cargo ships, the Santa Magdalena, Santa Maria, Santa Mercedes, and Santa Mar- iana, would be laid up at the end of February, along with the pas- senger ships Santa Rosa and Santa Paula. While the two passenger ships have been laid up permanently in Norfolk, Va., the four M-class ships have been given a reprieve and will continue to be used to carry bananas and other products between Port Newark, N.J. and the West Coast of South America. These four vessels will no longer have passengers, but will be used only for cargo.
