Emergency "yelp" and other signals can be acti- vated manually by the push-to-talk button on the microphone. All con- trols on the main console are by touch-keyboard.

For intercom communications, up to four remote stations can be con- nected to receive or initiate a call to the master station. An auxiliary in- put allows audio from an external source, such as radio or cassette, to be piped and amplified to all or selected stations throughout the vessel. The RAY-410 may also be used for burglar alarm functions.

Supplied with universal mounting yoke, the RAY-410 measures 6.5 inches high by 9.5 inches wide by 4.8 inches deep (165 X 240 X 120 mm), and can be mounted on a tabletop, bulkhead, or overhead.

The RAY-410 has passed Ray- theon's tough environmental tests for shock, vibration, temperature extremes, and resistance to corro- sion, fungus, and water penetra- tion.

American Piping Products, Inc., manufactures a complete line of quick-acting spectacle blinds, fea- turing forged-steel bodies. They are designed for marine piping systems which cannot tolerate leakage and are commonly used for cargo segre- gation, inert gas and ballast piping.

The company has made available sizes 1- through 24-inches, with either butt weld or flanged ends and a wide choice of body materials and "0" rings to suit the application. "O" ring seals located in the faces of the spectacle plate can be quickly replaced and eliminate the need for down-time servicing. A safety fea- ture of the American line blind is the position of the spectacle plate, which indicates the line to be open or closed.

American Piping Products is of- fering a free brochure detailing the applications, features and construc- tion of their spectacle blinds. The publication contains several cross- section diagrams of the units, along with weight and dimension charts.
