LOS ANGELES----To address the rising
cost of energy and protect the capital investment of industrial
equipment, Advanced Lubrication Technology's (ALT) Boron CLS Bond(R)
is the solution to improve fuel efficiency; reduce friction , heat,
wear and corrosion in engines and industrial equipment; and extend
engine and machine life .
According to Pat Desert, PhD, Director of University of Oakland's
Product Development and Manufacturing Center, major improvements in
lubrication technology only come along every 25 to 30 years and ALT 's
Boron CLS Bond(R) is an improvement of this magnitude. "Test results
from Herguth Labs and the Product Development Center at the University
of Oakland indicate that our new lubrication technology can be a
superior replacement for environmentally unfriendly, extreme-pressure
and friction reduction additives. CANTON, Ohio, The Timken Company
(NYSE: TKR) today announced that it will begin filling Timken(R) Fafnir(R)
ball bearing housed units with its own brand of pillow block grease.

"We have subjected Boron CLS Bond(R) to rigorous field and
laboratory testing by the some of the nation's leading independent
testing authorities," said Tom Foscue, chairman of ALT.
Products made by ALT using Boron CLS Bond(R) include both finished
lubricants and lubricant treatments in the form of and/or for addition
to the following: motor oils, gear oils, turbine oils, high
temperature lubricants, greases, hydraulic fluids, aerosol thin/dry
film sprays, diesel fuel and gasoline, mold release fluids, cold forge
fluids, and many other custom formulated products to address specific
needs. Etheridge, product manager - housed units .

Tribology is the study of friction, wear and lubrication of interacting surfaces in relative motion.

It
also helps remove particles that can potentially cause noise within the housed
unit, especially in textile and conveyor machinery, printing and packaging
machinery, food-handling machinery and harvesting equipment.

Typically these switches required hand
lubrication every week and the high traffic switches in the
inter-model yards (which average 1 ,200 switches per day) required hand
lubrication every hour.
Furthermore, ALT reformulated the Boron CLS Bond(R) lubricant into an
all weather highly visible lubricant that can readily be seen where
the applications are most heavily worn.

How Boron CLS Bond(R) Works

In practical application, the Boron CLS Bond(R) technology
chemically seals the host metal surfaces with a metallic boroxide to
prevent corrosion of the metal and metal induced oxidative breakdown
of the fluid lubricant.

Industrial Market Success

Work with Canadian National (CN) Rail began with an environmental
and lubrication problem related to rail switches. ALT has
already established the capabilities of the Boron CLS Bond(R)
technology through development of diverse applications for the
automotive aftermarket and a host of major industrial companies.com

Historically, used
engine oil was applied once a week to all switches to lubricate them
and make them easier to switch. Following the
issuance of the initial patent in 1995, ALT (as exclusive worldwide
licensee) invested millions of dollars over several years to develop
both additive and fully formulated products incorporating the key
technology discoveries that now provide a previously untapped
potential to a worldwide equipment market seeking greater
productivity, fuel efficiency and extended useful lives.
