No. 18326.—17th August, 1904.—THE NEW INVERTED
INCANDESCENT GAS-LAMP COMPANY, LIMITED, whose regis-
tered office is at 23, Farrington Avenue, London, England
(assignees of James Bridger, of 23, Farrington Avenue afore-
said, General Manager to said company). Improved means
for supporting the mantles in inverted incandescent gas-
lamps.

Extract from Specification.—To this end, the mantle-
supporting ring (of refractory material, or metal) is formed
or provided with small blocks or distance-pieces (say three),
from which spring or branch supporting devices or arms
(also of refractory material, or metal) of such a shape or
formation in cross-section as to straddle or fit over, or upon,
or into a corresponding number of triangular or equivalent-
shaped projections or lugs near the lower end of the burner-
tube. Or said supporting arms are formed at their inner end
with a notch adapted to engage the upper ends or apices of
the angular lugs or projections on the burner-tube.

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

No. 18657.—26th October, 1904. — BERTRAM GIBBS, of
Stoke, Nelson, New Zealand, Blacksmith. An improved
spreader for traces.

Claim.—A spreader for traces, the same consisting of a
bar of suitable material, to each end of which is attached a
flattened plate, formed with a tongue projection adapted to
enter a link of the trace, and with two holes passing down
through it, in combination with a pair of circular links
threaded loosely through the holes at each end of the
spreader, substantially as specified.
(Specification, 1s. 9d.; drawing, 1s.)

No. 18671.—25th October, 1904. — JOSEPH WELLINGTON
FERGUSON and GEORGE WELSH FERGUSON, both of Sydney
Road, Wangaratta, Victoria, Australia, Brickmakers. Im-
provements in brick- or briquette-making machines.

Extract from Specification.—The cycle of operation is as
follows: The material, after having passed through grinding-
rollers (situated in any suitable position), and in a plastic or
semi-plastic state, falls into the hopper J. It is then by the
worm forced through the shaping-passage L. As the top
and bottom of the brick passes the holes in the side walls of
the said shaping-passage some of the sand in the box C₁
adheres to the plastic material. This material continues
exuding until its outer end strikes the striking-plate B₁.
This plate forces the lever Y₁ outwardly from the machine
against the spring A₁, and the lever Y by the link X forces
the tappet S on the connecting-rod R into one of the teeth
of the rotating ratchet-wheel V. It is retained in gear by
the stud T bearing against the hopper side of the guide U,
and when it has passed the same the spring A pulls it to its
normal position. The connecting-rod is then drawn back-
wardly, and with it the lever Q, which turns the rocking-
shaft and depresses the cutter-lever P. As the lever P
descends so does the cutter M, and the clay is cut off and
falls into the mouth of the press-box D₁. A partition is
then dropped into the hopper, and the crank G₁, which is
now in gear with the clutch, forces the ram by the pit-
man F₁ against the said partition. The clay mould is then
forced forward in the press-box D₁, the sectional area of
which may diminish with some clays. The moulds gather
one behind the other, with a partition between each, and are
ejected one at a time. The ejecting-crank continues rotating
till its striking-surface R₁ strikes the clutch-lever P₁ and
throws the clutch out of gear with the crank. The said
crank then falls and rests upon a spring tongue or other
withdrawable rest A₂, and remains there till further material
is cut off and requires ejection. The clutch is again
engaged with the crank by the tappet S striking the tappet
end S₁ of the clutch-lever.

No. 18679.—1st November, 1904.—LEOPOLD NATHAN, of
Zurich, Ausstellungs strasse 104, Switzerland, Chemist.
Improvements in brewing beer.

Claims.—(1.) Process for the production of beer on the
sterilised system, with agitation of the wort during fermen-
tation, characterized by the supply to the liquor of a quantity
of air less than the amount which would be spontaneously
taken up or absorbed by the wort when allowed to cool to
normal atmospheric temperature. (2.) A practical modifica-
tion of the process claimed in claim 1, in which the deter-
minate quantity of air is gradually absorbed by the wort
while the latter cools until a certain predetermined tempera-
ture is reached. (3.) A practical modification of the process
claimed in claim 1, in which the air is supplied to the wort
during the cooling of the latter until its temperature falls to
50° C. (4.) A special modification of the process according
to claim 2, which consists in admitting CO₂ to the vessel in
order to prevent the formation of a vacuum after cutting off
the air-supply. (5.) A special modification of the process
according to claim 1, in which the agitation of the liquor
during fermentation is effected by blowing CO₂ through it.

No. 18692.—3rd November, 1904.—ROBERT LAW, F.I.C.,
F.C.S., of Claverton, Windermere Road, Brighton Beach,
near Melbourne, Victoria, Australia, Assayer. An improved
automatic temperature-regulator for incubators and foster-
mothers.

Claims.—(1.) The described automatic temperature-
regulator for incubators and foster-mothers, consisting of the
various parts constructed, arranged, and operating, sub-
stantially as and for the purposes specified, and as illustrated
in the drawings. (2.) An automatic temperature-regulator
for incubators and foster-mothers comprising a metallic or
electric contact thermometer, a cell or battery, and an
electro-magnet or solenoid, in combination with an arma-
ture upon a lever carrying a snuffer encircling the wick of
the heating-lamp, substantially as and for the purposes
specified, and as illustrated in the drawings. (3.) An automatic
temperature-regulator for incubators and foster-mothers
comprising a metallic or electric contact thermometer, a cell
or battery, and an electro-magnet or solenoid, in combina-
tion with a lever carrying a damper arranged to open
communication from the heating-flue to the atmosphere,
substantially as and for the purposes specified, and illus-
trated in the drawings.

No. 18693.—3rd November, 1904.—EDMUND ALBERT
ANGUS, of 1, Eglinton Street, Moonee Ponds, near Mel-
bourne, Victoria, Australia, Contractor. Improvements in
or relating to sewing-machines.

Extract from Specification.—The mechanism described
in detail in the following specification accomplishes the fol-
lowing functions: It pushes the empty bobbin out of the
bobbin-case and removes it, at the same time it brings a
freshly wound bobbin into position to be pushed into the
bobbin-case, pushes this in, threads the under-tension
(i.e., that upon the bobbin-case), cuts the cotton between the
freshly wound bobbin and the supply-reel, winds another
bobbin, and automatically throws the winding and charging
mechanism out of gear when the bobbin-case has been
recharged and the empty bobbin has been rewound, so that
there will be no unnecessary friction.

in place of the claims.]

No. 18695.—31st October, 1904.—WILLIAM DAWSON, of
44A, Shortland Street, Auckland, New Zealand, Photo-
graphic Engraver. Improvements in internal-combustion
engines and vaporisers.

Extracts from Specification.—The first part of my inven-
tion consists in an arrangement of vaporiser, which is heated
during the running of the engine by heat obtained from the
exhaust gases, but the heat so obtained is carefully regulated
by limiting conduction, so that the vaporiser is always kept
at a low temperature sufficient for vaporising but not suffi-
cient to cause destructive distillation and the production of
tar. . . . The second part of my invention consists in
an arrangement of automatic diaphragm pump, actuated
by pressure from the motor cylinder during the working-
stroke or by pressure from the exhaust gases during the dis-
charge. The third part of my invention consists in an im-
proved construction of governor, which is composed of a
number of sector-shaped blocks forming together in their
closed position a ring between a pair of guiding discs. The
rings are controlled by a spring which is slipped over pins
