Advantages of Patent Flattened Strand Ropes.

1.	Greater wearing surface, therefore longer life of rope and less wear

upon pulleys.

2.	Greater strength, thereby admitting of smaller ropes being used for

existing loads, or of increased loads without increase in size of rope.

3.	Spliced easily and more effectively.

4.	Less tendency to twist and stretch in working.

Fig. 13a for Sinking and Fig. lib for Cranes, &c., are non-twisting.

I say-because I know
that the Carbic System is
the most economical be-
cause the generation of
gas only takes place while
water is in actual contact
with the Carbic Cuke.
You shut the generator
down at night and start it
up again in the morning,
to find that no deteriora-
tion of the old charge has
taken place. Each Carbic
Cake is guaranteed to pro-
duce a stated number of

cubic feet of acetylene
either by continuous or
intermittent use.

IT WILL PAY to overhaul your Elect-
rical Plant periodically, laying out Armature
and Field Coils, and, after cleaning off dirt and
grease with a cloth wet with benzine, to give
them a Fresh Coat of Varnish. This will
Strengthen Weak Spots which may be de-
veloping in the insulation, and thus ward off
a Possible Breakdown.

The Varnish essentially suitable for this is

“INSULAC INSULATING COMPOUND.”
