Folk Disc Couplings
Feature Fast Assembly,
High Reliability "Fit-em and forget-em" disc cou- plings, combining unitized disc- packs for fast assembly with the rugged reliability offered from all- steel components, are now available from The Falk Corporation.
The heart of a disc coupling is a series of stainless steel plates held together in a laminated pack with high-strength alloy steel bushings and washers. These components form a unitized discpack for faster assembly and the elimination of loose parts. Flexibility is achieved when the laminated discpack bends between the driving and driven bolts.
Falk disc couplings feature no wearing parts to replace and require no lubrication, making them vir- tually maintenance free. Since there is no grease or oil to deal with, the couplings are not sensitive to hot or cold environments, and there is no danger of fluid leakage or contami- nation.
All component parts of Falk disc couplings are phosphate coated to resist corrosion, further extending the life of the unit.
The Falk Corporation, Milwau- kee-based subsidiary of Sundstrand
Corporation, is a major manufactur- er of industrial power transmission machinery, including standard and custom gear drives, flexible shaft couplings, backstops, fluid power drives, and fluid couplings.

Of GPS Data Outputs
The latest in Magnavox's growing line of GPS products is the MX 5400R, a "black-box" navigation re- ceiver that provides GPS data out- puts to a Magnavox MX 4102 OR
MX 5102 transit satellite navigation receiver.
The MX 5400R is a two-channel
C/A-Code GPS receiver that re- ceives and processes signals from orbiting satellites in the new Global
Positioning System (GPS). The sat- ellite signals are used to calculate a vessel's position and speed with a high degree of accuracy. The MX 5400R has no operating controls, and can be tucked away in any out- of-the-way location. GPS-derived data is formatted and transmitted to the MX 4102 or MX 5102, which acts as the display/control panel for the system.
Although the GPS satellite net- work is not yet fully operational,
Magnavox is already offering a vari- ety of GPS user equipment, giving users an opportunity to get an early start with the new system. GPS sat- ellite coverage is currently available for marine navigation up to 9-10
April, 1989 hours per day, using the six active prototype Block 1 satellites now in orbit. They will be supplemented, starting in early 1989, with addi- tional Block 11 satellites, and the system will be providing continuous worldwide position fixing by mid- 1990. Eventually, GPS will super- sede and replace the older Transit satellite navigation network, which has been in service since the 1960s.
The MX 5400R navigation receiv- er is specifically designed to work with Magnavox's popular MX 4102 and MX 5102 Transit satellite navi- gation receivers. Magnavox has de- veloped new software for its Transit receivers that permits the MX 4102 or 5012 to function as control center for the GPS receiver.
Interfacing the MX 5400R GPS module provides the MX 4102 or
MX 5102 user with the best satellite navigation performances available during the transition period , be- tween Transit and GPS and beyond.
And, unlike land-based radionavi- gation systems such as Loran-C, which depend on shore-based trans- mitters, the Transit and GPS sys- tems are available anytime, any- where.
