Hornsby, New South Wales, Australia, Engineer. An im-
proved apparatus for burning liquid fuel in conjunction
with steam.

Claims.—(1.) An apparatus for burning liquid fuel in con-
junction with steam, consisting of a burner having four
compartments — namely, a mixing-chamber, an insulated
valve chamber containing a check-valve, a heating-coil, and
a retort, and having a controlling valve for regulating the
supply of emulsion from the mixing-chamber, and a further
valve for regulating and spraying the emulsion into the
heating-coil ; means for introducing the oil into the burner
at the same pressure as the steam, and means for heating
the coil and the retort for the purpose of gasifying the emul-
sion of oil and steam prior to its emission from the burner,
substantially as described. (2.) The combination with a
furnace of a burner having four compartments—namely, a
mixing-chamber, an insulated valve chamber containing a
check-valve, a heating-coil, and a retort, and having a con-
trolling valve for regulating the supply of emulsion from the
mixing-chamber, and a further valve for regulating and
spraying the emulsion into the heating-coil ; and a pump,
accumulator, and pressure-gauge for the purpose of auto-
matically introducing oil into the burner at the same pres-
sure as the steam, substantially as described. (3.) The
combination with an oil-burner of the class described of a
pump and accumulator for the purpose of automatically intro-
ducing the oil or other liquid into the said burner at the same
pressure as the steam, substantially as described. (4.) The
combination with a furnace of a burner such as described,
and means for the initial heating of the retort thereof.

No. 19275.—30th March, 1905.—ALESSANDRO ARTOM, of
3 Via Venti Settembre, Turin, Italy, by profession Electrical
Engineer and Professor at the school “Galileo Ferraris” of
the “Royal Industrial Museum” of Turin. Improvements in
and relating to the transmission of electrical energy through
space for the purpose of wireless telegraphy and the like.

Extract from Specification.—This invention relates to a
method of transmitting electrical energy through space,
which may be applied for different purposes such as wireless
telegraphy. The characteristic feature of this method con-
sists in the use, for the transmission of signals or the like, of
circularly or elliptically polarised waves, which, as practical
experiments have demonstrated, tend to assume in space a
predetermined direction. The theory of this process has
been developed in the inventor’s notes before the Royal
Academy at the Lincei at Rome on the 15th March, 1903.
In carrying out this method, I produce oscillatory discharges
of different phase and at an angular relation one to another,
but of the same periodicity and amplitude, which discharges
are composed in circularly or elliptically polarised radiations.
When the method is used in connection with wireless tele-
graphy the radiations are received by a special receiving
apparatus, which resolves the circularly or elliptically polar-
ised radiations into their components, a suitable apparatus
being then operated for the registration of signals and the
like. The method may be carried out in a number of dif-
ferent ways, and the accompanying drawings illustrate one
mode of apparatus used for carrying into effect this inven-
tion. Fig. 1 is a diagrammatic view illustrating the trans-
mitting station. Fig. 3 shows another form of the transmit-
ting station. Fig. 4 illustrates a method by which the phase
displacement between two currents is obtained. Fig. 6 is a
diagrammatic view illustrating a transmitting station in
which a three-phase current is used.

No. 19276.—30th March, 1905.—GEORGE SKAATS MAY-
HEW, of 2, Basinghall Avenue, London, England, Engineer.
Improved assembling machine for forming a continuous
compo. board.

Claims.—(1.) An assembling-machine for joining slices
out from a deal, comprising a magazine for receiving said
slices, and a double reciprocating clutch frame or pusher for
feeding said slices from the magazine between guides forward
through the machine, a wiper adapted to glue respectively
the edges of each of said slices as it is passed from the maga-
zine, a fan or fans adapted to dust sawdust over the joints
formed between said slices, and a series of brushes surrounded
by heated air adapted to clean the compo. boards formed
from said slices of the superfluous glue after having been
dusted, substantially as described. (2.) In an assembling-
machine of the character described, a spring-controlled reci-
procating pusher adapted to feed a slice forward from the
magazine against the edge of the previous slice and to con-
trol the amount of pressure used in making the joint between
said slices, substantially as described. (3.) In an assembling-
machine of the character described, a glue-wiper mounted in
a glue-tank operated by cam mechanism to rise and fall in
said glue-tank, and adapted to wipe a small amount of glue
on to the edge of each slice as it is passed from the maga-
zine, substantially as and for the purpose described. (4.) In
combination with an assembling-machine as described in
claim 1, a lining-machine comprising upper and lower paste
or cement tanks provided with rollers adapted to convey
paste or cement to the upper and lower surfaces of the
compo. board, heated rollers adapted to compress and face
said board with paper after having been pasted, and upper
and lower guide-rollers adapted to guide a continuous sheet
of paper to said heated rollers, substantially as described.
(5.) In a modification of the lining-machine described in
claim 3, upper and lower cement-tanks provided with a com-
mon funnel adapted to convey cement under pressure
through spouts to the upper and lower faces of the compo.
board, grooved rollers adapted to form said paste into ridges,
and heated paper-rollers adapted to face said board with
paper or the like, and to spread said ridges of cement into a
solid structure with the paper and core, substantially as
described. (6.) In an assembling-machine, the construction
and arrangement of parts substantially as described, and

structions and arrangements of parts substantially as de-
scribed, and shown in the drawings.
