No. 27376.—2nd March, 1910.—Ernest Smith Baldwin,
of the firm of Baldwin and Rayward, of 215 Lambton Quay,
Wellington, New Zealand, Patent Attorneys (nominee of
Charles Henry Augustus Frederick Lockhart Ross, Baronet,
residing at Belnagown Castle, Ross-shire, Scotland, with
temporary address at Quebec, Canada). Improvements in
bullets.

Extract from Specification.—My invention relates to bullets
for firearms, and has for its object the production of a sharp-
nosed bullet that will readily open out upon striking the body
of an animal, and thereupon produce an explosive or mush-
rooming effect, and will at the same time be not liable to
have its point distorted during transportation or while in
the magazine. To these ends my invention consists in a
sharp-nosed bullet provided with a cavity, and a shell or
tube filling said cavity, with a point, coming under the classi-
fication of what is known as a sharp-pointed bullet.

[Nom.—The above extract from the specification is inserted in place
of the claims.]

No. 27429.—15th March, 1910.—Carl Neff, of 19
Georgstrasse, Hanover, Germany, Banker, and August
Brandes, of 8 Hildesheimerstrasse, Hanover aforesaid,
Mechanic. Improvements in and relating to the treatment
of liquids.

Claim.—A method of treating liquids, and especially water,
by the exposure of the water to the action of sunlight in
passing over a surface of a metal such as aluminium, sub-
stantially as described.

(Specification, Is. 6d.)

No. 27438.—15th March, 1910.—Dr. Wilhelm Schmidt,
Engineer, of 2 Rolandstrasse, Cassel-Wilhelmshohe, Germany,
and Peter Thomsen, of Cassel-Wilhelmshohe aforesaid. Im-
provements in steam-superheaters for locomotives.

Extract from Specification.—The primary object of the
present invention is to provide a superheater for locomotives
which may be applied to any locomotive having smoke-tubes
of normal diameter without having to substitute any tubes
of abnormal diameter. With this object the present invention
consists in a locomotive-superheater comprising a plurality
of tube elements bent in the form of a U and inserted into the
smoke-tubes of normal size, one end of each tubular element
being connected directly or indirectly to a saturated steam-
distributor, and the other end being similarly connected to
a superheated steam-collector.

of the claims.]

No. 27441.—15th March, 1910.—Henri Donner, of
Sophieka, 17 Log. 8, Moscow, Russia, Engineer. Improved
process and apparatus for obtaining an increase in the pressure
of a liquid.

Extract from Specification.—According to my invention, I
insert in the pipe apparatus, comprising three or more com-
partments arranged in series. The first compartment is of
constant capacity, and the pressure in it is always equal to
that in the inlet-pipe; the third compartment is of a capacity
which periodically increases and diminishes, and the pressure
in it is a function of that in the first compartment, and also of
a constant force; lastly, the second or equilibrium compart-
ment can communicate with the other two compartments, and
the pressure in it varies between that in the first and that in
the third. Liquid—water for example—entering the first com-
partment at any pressure that it may have passes through
the middle or equilibrium compartment to the third or high-
pressure compartment, and issues therefrom at an increased
pressure.

[Nor.—The above extract from the specification is inserted in place
of the claims.]

(Specification, 5s. 6d.)

No. 27450.—22nd March, 1910.—Stanley Tynwald
Gelling, of Schoolhouse, Braddan, Isle of Man, Mining-
engineer. Improvements in pumps.

Claim.—In balanced pumps of the kind, having two separate
pumps connected up to work as a double-acting pump, forming
each pump of two or more barrels or cylinders, the upper
barrels or cylinders each terminating in a vertical discharge-
pipe arranged at one end of the pump, and the lower barrels
or cylinders terminating in valve-boxes furnished with suction-
valves, in combination with hollow plungers working in the
cylinders or barrels connected together at one end and pro-
vided with discharge-valves in the turn or junction of such
plungers, the said plungers being supported upon slippers or
rollers sliding on a race provided and reciprocating in unison,
substantially as described and shown.

(Specification, 3s. 6d.)

No. 27452.—22nd March, 1910.—Gilbert Lang, of 29
Aytoun Road, Pollokshields, Scotland, and Matthew Mc-
Ewen, of 10 Walmer Crescent, Paisley Road, Glasgow,
Scotland, Solicitor and Traveller respectively. Improvements
in sheet-metal saucepans and the like.

Extract from Specification.—Some of the objects of our
invention are to make a sheet-metal saucepan which can be
utilised for other purposes. With this object in view we make
our improved saucepan with a metal handle, which can be
removed from and applied at will to an air- and liquid-tight
(cylindrical or other shaped) cheaply constructed pan which
is free from any corrosible, raw, metal edge within it, or any
internal groove or projection which might prevent its con-
tents being fully extracted, and having a collar-part adapted
to receive an ordinary air- and liquid-tight lever-lid, so that its
contents may be preserved from deterioration and safely
parcelled and carried when the lid is on; also that a quantity
of such pans or their handles may be parcelled very com-
pactly together for storage and transit.

[Note.—The above extract from the specification is inserted in place
of the claims.]

No. 27456.—23rd March, 1910.—Charles Thomas
Swanell, of Melbourne, Victoria, Australia, Engineer. Im-
provements in smoke-consuming apparatus.

Claims.—(1.) In smoke-consuming apparatus of the class
described, the employment of means for admitting and con-
trolling the air-supply to the air-chamber, comprising a
slidable damper adapted to be operated in guideways, so that
the air may enter either at its front or rear ends, in com-
bination with a pivotally dependent air-baffle disposed in the
ash-pit and adjacent to the inlet-opening of the base-plate,
for the purpose described. (2.) In a smoke-consuming
apparatus of the class described, a deflecting-plate adjustably
disposed at the rear of an arched fire-bridge and supported
by a concave seat and notched ears or lugs projected from the
outer side fire-bars of said bridge, for deflecting in the desired
direction the air admitted to the air-chamber, for the purpose
specified. (3.) In smoke-consuming apparatus of the class
described, the combination with the arched fire-bridge, having
a concave seat formed at the rear of the fire-bars thereof and
notched ears or lugs projected therefrom, of an adjustable
plate disposed in the air-chamber, for angularly deflecting the
air admitted thereto, as herein set forth. (4.) In a smoke-
consuming apparatus of the class described, the means for
preventing the damper jamming in its guideways, consisting
of two clearance-gaps situated at the inner ends of said guide-
ways, as and for the purpose set forth.
