Literature Available On Tracor Automatic Omega A new brochure on its auto- matic Omega navigation system is available from Tracor, Inc., Austin, Texas. The Tracor Automatic Omega is said to provide the capability to reestablish a position fix even if "lost" by as much as 100 miles. This is possible by judicious use of a fourth transmitter combined with the three-frequency recep- tion of the Omega receiver. Complete navigation informa- tion supplied by the Tracor sys- tem includes latitude and longi- tude ; GMT and date; input speed —manual or automatic; input heading — manual or automatic; great circle course and distance; and dead-reckoning status. The receiver automatically per- forms synchronization, transmit- ter selection, propagation correc- tions, three-frequency lane checks, diagnostic routines, and switch- over to standby battery. The op- erator is required only to turn on the receiver and enter initial latitude, longitude, GMT, and day. For additional information and a free copy of the brochure, write to John L.

(N62665- 77-C-0007) Goodyear Brakeability: Disc brakes, more efficient, more effective than band brakes under dynamic operation. As a leader in disc brake technology, we supply brakes for bow thrust engines, propeller shafts, anchor windlasses, winches, as well as other uses. Disc brakes offer many advantages over band and shoe brakes. They are smaller. They can perform in both static and dynamic situations. Their non-self-energizing characteristic assures smooth, controlled payout and superior brake control. The large exposed disc surface dissipates more energy and heat. Goodyear manufactured friction materials exhibit minimum fade at elevated temperatures and high energy input rates. As the linings wear, pistons continually advance, keeping displacement constant for each application. Quick-change lining design allows minimum downtime for replacement. Our disc brakes are available in a complete line of caliper designs from 2x/i lb. to 300 lb. units. By varying caliper multiples, disc thicknesses, operating pressures, etc., one brake caliper can be used across a complete product line. For complete information, call Jim Evans, Marketing Manager, Industrial Brakes, Goodyear Aerospace Corporation, Box 427, Berea, Kentucky 40403, (606) 986-9381. We Ic now how to malce things work.
