_A._–When a boiler gets into this state the whole of the tubes must be
pulled out, which may be done by a Spanish windlass combined with a pair of
blocks; and three men, when thus provided, will be able to draw out from 50
to 70 tubes per day,–those tubes with the thickest and firmest
incrustations being, of course, […]

overhead conductor joined to the positive pole of the dynamo or
generator in the power house, and C is a rolling contact or
trolley wheel travelling with the car and connected by the wire W
to an electric motor M under the car, and geared to the axles
The system will be understood from figure 77, where L is […]

competent account of his work published in Paris in 1910
We will take first Ader”s own statement as set out in a very
competent account of his work published in Paris in 1910. Here
are Ader”s own words: “After some turns of the propellers, and
after travelling a few metres, we started off at a lively pace;
the […]

_A._–Bad fitting, deficient surface, and too tight screwing down.
Sometimes the oil hole will choke, or the syphon wick for conducting the
oil from the oil cup into the central pipe leading to the bearing will
become clogged with mucilage from the oil. In some cases bearings heat from
the existence of a cruciform groove on the top brass […]

of these double-surfaced machines last June
“Herr Lilienthal kindly allowed me to sail down his hill in one
of these double-surfaced machines last June. With the great
facility afforded by his conical hill the machine was handy
enough; but I am afraid I should not be able to manage one at
all in the squally districts I have had to […]

inclination, revolving it on the line of nodes as an axis until
it was turned 85, the moon, still continuing on its orbit in that
plane, would go over the poles instead of about the equator, and
would go back to its old path when the plane was revolved 180;
but its revolution would now be from east to […]

A. These valves are connected to the steam ports at each end of the
cylinders and open to allow air and steam to pass from one end of the
cylinder to the other; away from the moving piston when the engine is
drifting. If not kept clean they may stick open; when working steam the
engine will blow badly; […]

The protocol is not well documented. A group of people
are working on producing an RFC to both define the
current RIP and to do some extensions to it to allow it
to better cope with larger networks. […]

use a much larger nozzle and flame than for metals which have not this
property
In welding metals which conduct the heat very rapidly it is necessary to
use a much larger nozzle and flame than for metals which have not this
property. This peculiarity is found to the greatest extent in copper,
aluminum and brass.

be applied thereto, the water, if allowed to flow out of an orifice,
will carry with it a certain quantity of sand, according to the
velocity, and the observation of this might easily give rise to the
erroneous impression that the sand, as well as the water, was flowing
out under pressure, and, as heretofore stated, has caused many […]
