No. 23891.—15th January, 1907.—ROBERT BROWN, Junior,
of 34 Mansfield Road, Ilford, Essex, England, Merchant.
Improvements in stoppering bottles.

[NOTE.—This is an application under section 106 of the Act, the date
given being the official date of the application in Great Britain.]

Claims.—(1.) An attachment for stoppering bottles con-
structed substantially as described and for the purposes
set forth. (2.) An attachment for stoppering bottles to pre-
vent fraudulent refilling of same, comprising a cap portion
resting on the top of the bottle, such cap portion being pro-
vided at the bottom with notches and being furnished with
a screw shaft which can be screwed down in such a way as
to close a valve at the top of the bottle, in combination with
a sleeve or capsule for holding the said cap on the top of the
bottle, all substantially as described, and shown on the draw-
ing. (3.) An attachment for stoppering bottles to prevent
the fraudulent refilling of same, comprising a permanent part,
which permanent part can be used repeatedly, and is pro-
vided with a screw or its equivalent controlling a valve at
the top of the bottle, and a temporary portion, such as a
capsule or sleeve, which when in position holds the first-
mentioned permanent portion in place, and can be renewed
whenever the bottle is refilled by the owner, but will bear
evidence of any fraudulent tampering with the bottle.

No. 23897.—4th January, 1908.—FRANCIS WILLIAM PAYNE,
Dunedin, New Zealand, Consulting Engineer. Improvements
in apparatus for lifting water by power obtained from running
water.

Extract from Specification.—I place a water-motor, prefer-
ably of the paddle-undershot or of the oblique-float type,
according generally to the depth of the water, the latter
wheel requiring deeper water to submerge it. With this
power I work a pump, preferably a centrifugal one, which
raises water, passing it through uptake-pipes which are
arranged so as to allow for the movements of the pontoon on
which this machinery is placed, and also for any fall or rise
in the level of the stream on which the said pontoon floats.
This is allowed for by connecting the pipes with ball or swivel
joints, or with expansion joints if necessary, as well as by
supporting the pipes where needed.

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

No. 23900.—8th January, 1908.—FRANCIS REGINALD
SIMMONDS and WALTER SEIFERT, both of Takapau, New Zea-
land, Flax-millers. Improved means for dressing or trueing-
up the beater-bars of flax-strippers and the like.

Claims.—(1.) In means for the purpose indicated, a file or
bar having an abrading-surface supported horizontally across
the top of the beater-drum and adapted to engage with the
surfaces of beaters, and means whereby such file or bar may be
held and adjusted in relation thereto, as specified. (2.) Means
for the purpose indicated comprising, in combination, a pair
of side-cheeks adapted to be secured one on each side of
the stripper-drum, and each having a vertical slide therein,
a file or bar having an abrading-surface extending across
the drum, and with its respective ends fitted into the corre-
sponding slides in the side-cheeks, a helical spring supported
vertically in each slide and upon the top end of which the
corresponding end of the file or bar is placed, and a set-screw
threaded vertically down through the top of each cheek
and bearing upon the end of the file or bar beneath, substan-
tially as specified. (3.) The general arrangement, construc-
tion, and combination of parts in our improved means for
dressing or trueing-up the beater-bars of flax-strippers and the
like, substantially as described and explained, and as illustrated
in the drawings.

No. 23905.—8th January, 1908.—MAX ULRICH SCHOOP,
of Villa Plaisance, Garenne-Colombes, near Paris, France,
Electro-chemist. A process for autogenously soldering or
welding aluminium and alloys rich in aluminium.

Claim.—The process of autogenously soldering or welding
aluminium or alloys rich in aluminium with the aid of a
flux in the form of liquid, paste, or powder, consisting of a
mixture of fluorides with chlorides and other haloid salts of
the alkali metals.

(Specification, 1s. 6d.)

No. 23906.—8th January, 1908.—JOHN RUTHERFORD
PARK, a member of the firm of A. J. Park and Son, of 131
Princes Street South, Dunedin, New Zealand, Registered Pa-
tent Agent (the nominee of Pintsch’s Patent Lighting Com-
pany, Limited, of 38 Leadenhall Street, London, England,
Manufacturers—the assignees of Otto Schaller, of 39 Albrecht-
strasse, Steglitz, near Berlin, German Empire, Engineer).
Improvements in the regulation of the electric potential
of a network supplied by a generator which is driven at very
variable speeds.

Extract from Specification.—With considerable fluctuations
of speed of the driving-shaft of a dynamo-electric machine
the terminal voltage of the machine varies within wide limits.
The object of this invention is to obtain a constant or fairly
constant voltage in a network supplied by such a machine,
and with this object an independently driven auxiliary machine
is employed which is so related electrically with the variable-
speed machine, and with a constant source of current such as
a storage battery which is employed in conjunction therewith,
that the algebraic sum of the voltages of the two machines
on which the voltage of the network depends is substantially
constant. According to one arrangement by which this re-
sult is achieved, the two machines are so related that the
algebraic sum of their speeds, and therefore of their voltages,
remains substantially constant. In a modified arrangement
in which the two dynamo are combined in a single machine,
the relative speed of the relatively revolving parts remain
approximately constant.

of the claims.]

Process for the extraction of metals and metalloids from their
ores or compounds.

Claims.—(1.) An improved process of manufacturing
products conducting electricity in a cold state, or first-class
conducting bodies, characterized in that the product is ob-
tained by simply melting, or in certain cases by melt-
ing in presence of oxygen, bodies, earths, or materials
appertaining to the group of second-class conductors,
said bodies, earths, or materials containing naturally
metallic oxides, or metallic oxides being artificially incor-
porated to the same, substantially as and for the purpose
set forth. (2.) The application of the process specified in
claim 1 to the manufacture of first-class conducting products

purpose set forth. (3.) The application of the process specified
in claim 1 to the manufacture of first-class conducting pro-
ducts by treating an easily reducible natural or artificial
oxide—viz., oxide of chrome, oxide of iron, and the like—
said oxide being melted in presence of oxygen so as to avoid
reduction, substantially as and for the purpose set forth.
(4.) The application of the process specified in claim 1 to the
manufacture of first-class conducting products by treating
a metal producing a melted oxide by melting said metal in
presence of oxygen so as to bring the same to a suitable
