towards said lift, a carrier or carriers upon the railway,
means for reducing the speed of the carriers, a lever pivotally
mounted in the elevator-frame that is engaged by the pro-
jection aforesaid, a vertical slotted piece as 27 supported in
an extension of the elevator-frame that receives the end of
the lift and against which the carrier that is contained in
the lift will rest until lifted clear thereof, buffers upon the
carrier-frames that are made sufficiently deep for those of

No. 17164.—23rd October, 1903.—EDWARD KNEWSTUBBS,
of Port Chalmers, New Zealand, Shipwright. Improvement
in depositing dredged material.

Claims.—(1.) In the depositing of dredged material, the
combination of the main tables D with side chutes E, E,
into which, when required, stuff not requiring treating may
be turned, said chutes preferably delivering said material
farther from the dredge than stuff that is treated, substan-
tially as set forth, and as shown on the drawing. (2.) In the
depositing of dredged material, the combination of the main
tables D with the side chute E, said chutes being either of
them capable of taking the dredged material, and chute E
being preferably longer than tables D, substantially as set
forth, and as illustrated in the drawing. (3.) In the deposit-
ing of dredged material, doors or guides F, admitting dredged
material as required to either the tables D, or to the chute
E, or chutes E, E, substantially as set forth.

No. 17181.—29th October, 1903.—EDGAR ARTHUR ASH-
CROFT, of “The Birches,” Weston (vid) Runcorn, Chester,
England, Mining Engineer. Improved process and appa-
ratus for the production of metals of the alkali group by
electrolysis.

Claims.—(1.) The production of alkali metal by the use of
a fused alloy of the alkali metal as an anode in an electro-
lytic cell in which the electrolyte is not consumed. (2.) The
process of producing alkali metal, which consists in deposit-
ing the metal as an alloy by electrolysis of the fused chloride,
and using the alloy as the anode in a second electrolytic
cell, whether the cells are separate or combined. (3.) In
the production of alkali metal, the use of a double electro-
lytic cell with an intermediate electrode, forming an alloy
with the alkali metal, the electrolyte in the first cell being
the fused chloride, and that of the second cell being a salt of
the alkali metal which is not consumed. (4.) The process
of producing an alkali metal, which consists in electrolysing
the fused chloride over a cathode which forms a fusible
alloy with the alkali metal, and thereafter using the alloy
as an anode in an electrolytic cell containing as an electro-
lyte a salt of the alkali metal which is not consumed. (5.)
In the production of alkali metal by the electrolysis
of the fused chloride separating the chlorine from the alkali
metal in one cell, and removing the metal as a fused alloy
to a second cell, where it is used as an anode with an electro-
lyte which yields only the alkali metal at the cathode in an
electrolyte which is not consumed. (6.) The process of pro-
ducing sodium, which consists in electrolysing fused chloride
over a cathode of fused lead, and thereafter using the result-
ing sodium-lead alloy as anode in an electrolyte of sodium-
hydrate or the like, which yields sodium at the cathode and
is not consumed. (7.) The complete apparatus for producing
alkali metals substantially as described or illustrated in
Figs. 1, 2, and 3 or in Fig. 4 of the drawings.
(Specification, 10s.; drawings, 3s.)

No. 17185.—10th November, 1903.—ROBERT WALKER ASH-
CROFT, of Palmerston North, New Zealand, Plumber. A
tank-cleaning overflow.

Claims.—(1.) In a tank-cleaning overflow, a pipe fixed in
a vertical position, the top end being fixed through the tank
and left open, and the bottom end being fixed close to the
bottom of the tank. (2.) In a tank-cleaning overflow, a pipe
fixed in a vertical position having a tee branch fixed close to
the top of the pipe and carried through the side of the tank.
(3.) In a tank-cleaning overflow, a pipe fixed in a vertical
position having a tee branch close to the top of the pipe and
carried outside the tank, the bottom of the pipe having a
disc of flat sheet metal surmounted with a strengthening
cone also of flat sheet metal. Substantially as set forth and
described.
(Specification, 1s. 6d.; drawing, 1s.)

No. 17190.—4th November, 1903.—JOHAN ALFRED
DAHLQVIST, of Odengatan 16, Stockholm, Sweden, Engi-
neer. Improvements in liners for centrifugal-separator
drums.

Claim.—The combination with a centrifugal-separator
drum, having a liner consisting of conical plates which
radially divide the contents of the drum into thin layers of
inclined wings between the outer edges of the said mantles
and the inside of the drum, substantially as and for the pur-
pose set forth.
(Specification, 2s.; drawing, 1s.)

No. 17210.—3rd November, 1903.—ALEXANDER KNOX, of
153, Queen Street, Brisbane, Queensland, Merchant. Im-
provements in electrical time service, and apparatus therefor.

Claims.—(1.) In an electric clock, the combination of a
going-train, a winding-device actuating the same, an electro-
magnet capable of periodically winding up the driving-device
on completion of the circuit, a vibrating armature to said
electro-magnet, and a contact device formed of a moving
part of the driving-device and the said armature whereby
when the driving-device has run down to a given extent it
shall make contact with the armature and thus close the
circuit and allow the electro-magnet to wind or set up the
winding-device. (2.) In an electric clock, the combination
of an escapement device A, a driving-wheel C, oscillating
lever c having pawl cl and contact arm c3, the electro-
magnet and armature d, with an electric circuit controlling
the magnet and made whenever the lever-arm c3 comes in
contact with the armature, whereby whenever the arm c is
caused to descend sufficiently by the weight cl a contact is
made, the magnet draws in the armature which throws up
the lever, thus rewinding the clock. (3.) An electric clock
in which the driving-device is automatically wound up by
an electro magnet (as described with reference to Fig. 1),
and in which the power required to drive it is stored in a
spring instead of in a weight, the use of a geared fly-wheel,
substantially as and for the purposes described. (4.) In a
clock-dial apparatus in which an intermittent electric
current is employed to revolve the hands, the combination of
an electro-magnet B, toothed wheel A, backstop click G,
stop H, rocking-lever D with armature C at lower end and
driving-pawl at top end whereby the wheel A is propelled,
substantially as described, and shown in Fig. 3.
