Cotton waste Transforrnsd Into Nitrate
Of Ceiluiose-A New Dynamo.
An interesting discovery has been
made by two young chemists Of Lon
don which will doubtless have a very
important bearing on the manufacture
OF cotton, says London correspon-
dent of the New York Times. Cotton
waste is transformed by a new process
into nitrate of cellulose, and cotton
fabrics can be covered with a solu-
| tion of IL which will add materially to
the weight, strength and value Of the
material. Thin, lightweight fabrics
can be filled up with this preparation,
which costs little more than sizing and
I fuller's earth. The cellulose thus pre-
/ pared is also applicable TO many differ
/ ent purposes The cost Is very little
more than the raw material, being
cheap and the process of manufacture
inexpensive.
Another invention Of moment is one
which enables waste paper TO be CON
verted into kegs, barrels and vessels
I Of every description. In making kegs
and barrels ingenious machinery is EN-
ployed, which enables the manufac-
turer to turn them out with solid heads
II desired. There will be a large de-
mand for the product In the shape of
kegs and barrels for powder, as no
dampness can be contracted, since they
are water and damp proof
The latest improvement In dynamos
is one which gives a continuous cur
rent without brushes and acoumula-
tors. Scientists were incredulous and
/ pronounced this impossible, but the
proof of the pudding is in the eating,
and the new dynamo gives a strong
and continuous current notwithstand-
ing IL was declared an impossibility.
At least one of the first electricians Of
England, who was an unbeliever, now
certifles that the new dynamo is a sue
cess.
Most important improvements have
been made by an Austrian long domi-
ciled in England In methods aud appa-
ratus for distillation. new ferment
has been discovered, and improve
ments have been made in distilling ap-
paratus and In mashing machinery and
appliances which promise TO complete-
ly revolutionize the manufacture of
spirits. The bye products which are
saved md utilized leave the spirits al
most free of cost. The still Is a most
important invention, since It separates
the fusel oil and other products from
the spirits In the process of distilla-
tion, giving In three separate receivers
the three distinct products, and, If re-
quired, by a simple change in the ap-
paratus, instead of getting high wines,
pure neutral spirits can be obtained,
thus obviating separate rectification to
produce refined alcohol The ferment
is made fresh for each mash and there
results luxuriant crop of yeast,
which Is treated and sold to bakers
and for domestic purposes This alone
is a source of large revenue TO the dis.
tillers, as the yeast is of q very superi.
or quality and the demand for It IL
practically unlimited. The yield OF
spirits Is more than one-fourth more
than by old processes. Green malt In.
stead of dried malt is used, which is a
source of considerable economy. The
very best Irish and Scotch whisky is
produced and fifty per cent. raw maize
substituted for the matted oats hereto
fore used, which in itself effects very
large saving.
