mately tuning the strings, whilst the other set of pins is
intended to depress the strings after they have been approxi-
mately tuned, so as to enable the pitch to be increased or
decreased, according to requirements, with great accuracy
and precision. These last-mentioned pins are referred to as
“tuning-pins,” and exert their pressure upon the wires or
strings at a convenient point above the customary upper
bridge and beyond the pressure bar—that is to say, at a
point beyond the intended vibrational length.

No. 20081.—22nd September, 1905.—ELIJAH MARK
HOUGHTON, of 130, Longfellow Avenue, Detroit, Michigan,
United States of America, Chemist. Black-leg vaccine and
process of making same.

Claims.—(1.) The described process of making black-leg
vaccine, which consists in powdering the dried muscles
obtained from an animal infected with black-leg, attenu-
ating the virus by heat, separating the finer particles from
the coarser, mixing said finer particles with a protein sub-
stance, and subjecting the weakened virus to a second heating
and dried. (2.) A dry attenuated vaccine containing the
finer particles of muscles of infected animals mixed with
normal serum and dried. (3.) A dry attenuated vaccine con-
taining the finer particles of muscles of infected animals mixed
with a normal cow serum and dried. (4.) A heat-attenuated
vaccine containing the finer particles of muscles of animals
infected with black-leg mixed with normal serum and dried.
(5.) A heat-attenuated vaccine containing the finer particles
of muscles of animals infected with black-leg mixed with
normal cow serum and dried. (6.) The described black-leg
vaccine consisting of a product obtained from the dry muscles
of an animal infected with black-leg, which product has
been heat-attenuated and mixed with normal cow serum,
the product being again attenuated and caused to be of
known and uniform verity and dried. (7.) The described
process of making black-leg vaccine, which consists in powder-
ing the dry muscles obtained from an animal infected with
black-leg, attenuating the virus and separating the finer
particles from the coarser, mixing said finer particles with a
protein substance, and finally subjecting the weakened virus
to a second attenuation and dried.

walls for partitions and the like consisting in moulding
them from plastic or semi-plastic material, series of vertical
tubular holes being formed in said partition, substantially as
specified and illustrated. (3.) In the construction of parti-
tions of the kind referred to, the employment of stay-wires
substantially as specified and illustrated.

Claims.—(1.) The combination of a motor-wheel casing, a
motor-wheel fast on its shaft, an air-fan fast on said shaft,
between said wheel and fan a series of concentric open-ended
cylinders spaced apart, and a rotatable liquid-distributor
which rotates slower than the fan is opposed to the cylinder-
ends and supported by a stationary part of the machine, the
casing being vented. (2.) The combination of a motor-wheel
casing, a motor-wheel fast on its shaft, an air-fan fast on said
shaft, between said wheel and fan a series of concentric open-
ended cylinders spaced apart, a rotatable liquid-distributor
which rotates slower than the fan is opposed to the cylinder-
ends and supported by a stationary part of the machine, a
pair of annular air-deflectors spaced apart, and an annulus of
separated baffle-plates in said space. (3.) The combination
of a motor-wheel casing, a motor-wheel fast on its shaft, an
air-fan fast on said shaft, between said wheel and fan a series
of concentric open-ended cylinders spaced apart, a rotatable
liquid-distributor which rotates slower than the fan is
opposed to the cylinder-ends and supported by a stationary
part of the machine, a pair of annular air-deflectors spaced
apart, an annulus of separated baffle-plates in said space,
and an annulus of separated baffle-plates between the
cylinders and air-fan. (4.) The combination of a motor-
wheel casing, a motor-wheel fast on its shaft, an air-fan fast
on said shaft, between said wheel and fan a series of con-
centric open-ended cylinders spaced apart, a rotatable liquid-
distributor which rotates slower than the fan is opposed to
the cylinder-ends and supported by a stationary part of the
machine, a pair of annular air-deflectors spaced apart, an
annulus of separated baffle-plates in said space, a shell
enclosing said cylinders, a troughed annular frame into
which the shell discharges, and a series of discharge-tubes
depending from the trough and extending below the baffle-
plates which are inclined crosswise to the inclination of the
vanes of the air-fan. (5.) The combination with a motor-
wheel casing, a motor-wheel, its shaft, an air-fan fast on the
shaft, a series of concentric open-ended cylinders, annular
air-deflectors spaced apart, a supply-pipe and an escape-pipe,
all substantially such as described, of means for preventing
the escape of water through the space between the air-
deflectors, and means for distributing water over said
cylinders in a series of separated streams. (6.) In apparatus
substantially such as described, the combination of a motor-
wheel casing, a regulable liquid-jet nozzle therefor, an air-fan
fast on a shaft on which the motor-wheel is fast, and a
liquid-distributor which has arms provided with regulable
vanes against which liquid from said wheel strikes, and also
has troughed arms with liquid-escape ports. (7.) In ap-
paratus substantially such as described, the combination of a
pan, an upwardly and outwardly extending air-deflector
therein having such shape as to form a dead air-space at the
lower corner of the pan. (8.) The combination of air-
modifying apparatus with an air-intake device having regu-
lable air-inlets, one opening into the room of installation and
another opening outside of the room of installation. (9.) The
combination with air-modifying apparatus having a motor-
