Any withdrawal of gas will, of course, lower the pressure of that remaining
inside the regulator. The spring tension, remaining at the point determined
by the operator, will overcome this lessened pressure of the gas, and the
valve will again open and admit enough more gas to bring the pressure back
to the starting point. This action […]

Later experimenters in this direction were Kress, a German;
Professor Wellner, an Austrian; and W. R. Kimball, an American.
Kress, like most Germans, set to the development of an idea
which others had originated; he followed de la Landelle and
Forlanini by fitting two superposed propellers revolving in
opposite directions, and with this machine he […]

Thursday, August 30th, 2007In the above year, Thomas L. Willson, an electrical engineer of Spray,
North Carolina, was experimenting in an attempt to prepare metallic
calcium, for which purpose he employed an electric furnace operating on a
mixture of lime and coal tar with about ninety-five horse power. The result
was a molten mass which became hard and brittle when cool. This […]

It is absolutely necessary that both parts be heated uniformly and so that
they reach the welding temperature at the same time. For this reason they
should be as close together in the fire as possible and side by side. When
removed to be hammered together, time is saved if […]

The Monarch Company provides in another way for code signaling at the
switchboard. In some cases there is a special attachment, shown in
Fig. 260, by means of which the code signals are repeated on the
night-alarm bell. This is in the nature of a special attachment
placed on the drop, which consists of a light, flat spring attached […]
