This machine, which is 2 meters in length by 1 meter in width,
requires a one-third horse power to actuate it. It weighs altogether
about 800 kilogrammes.--_Annales Industrielles._

A NEW EVAPORATING APPARATUS.
At a recent meeting of the _Societe Industrielle_ of Elbeuf, Mr. L.
Quidet described an apparatus that he had, with the aid of Mr. Perre,
invented for evaporating juices.
In this new apparatus a happy application is made of those pipes with
radiating disks that have for some time been advantageously employed
for heating purposes. In addition to this it is so constructed as to
give the best of results as regards evaporation, thanks to the lengthy
travel that the current of steam makes in it.
[Illustration: PERRE & QUIDET'S EVAPORATING APPARATUS.]
It may be seen from an examination of the annexed cuts, the apparatus
consists essentially of a cylindrical reservoir, in the interior of
which revolves a system formed of seven pipes, with radiating disks,
affixed to plate iron disks, EE. The reservoir is mounted upon a
cast-iron frame, and is provided at its lower part with a cock, B,
which permits of the liquid being drawn off when it has been
sufficiently concentrated. It is surmounted with a cover, which is
bolted to lateral flanges, so that the two parts as a whole constitute
a complete cylinder. This shape, however, is not essential, and the
inventors reserve the right of giving it the arrangement that may be
best adapted to the application that is to be made of it.
