said, Manufacturers). Improvements in the manufacture of
soap or mixtures containing soap.

Claims.—(1.) Injecting a hydrocarbon oil in a finely divided
or pulverised condition into a soap, or a mixture containing

scribed. (2.) Carrying out the process claimed in claim 1 in
the presence of an alkali.

No. 23820.—7th December, 1907.—SIR WALTER PALMER,
Baronet, of 50 Grosvenor Square, London, England, and
FRANCIS ERNEST BLACKMORE, of Hillsboro, Glebe Road, Read-
ing, Berks, England, Engineer. Improvements in apparatus
for working, or kneading, compressing, and amalgamating
plastic substances such as dough used in making biscuits.

Claims.—(1.) Apparatus for the purposes aforesaid, con-
sisting of, or comprising, a receptacle with stationary ends and
movable sides inclined towards the exit, and means for causing
the said movable sides to operate on the dough, or equivalent
material, in the manner described. (2.) Apparatus for the
purposes aforesaid, consisting of, or comprising, a receptacle
with stationary ends and movable sides inclined towards each
other towards the exit, and provided with a rib, or ribs, or
equivalent projection, or projections, and means for causing
the said movable sides to operate on the dough, or equiva-
lent material, in the manner described. (3.) In apparatus in
accordance with either of the preceding claiming clauses, pro-
jections, or recesses, on, or in, the stationary ends to pre-
vent the dough, or equivalent material, being operated upon,
from adhering to the movable sides as they recede from the
dough, or equivalent material, substantially as described.
(4.) The constructions of apparatus in accordance with the
preceding claiming clauses, substantially as described and
illustrated in Figs. 1 and 2, Fig. 3, and Fig. 4 of the draw-
ings, whether either, or both, of the movable sides be plain,
or be provided with a rib, or projection, or ribs, or projections,
or the like.

No. 23825.—10th December, 1907.—JOHN COLIN LIVING-
TON CAMPBELL, late Lieutenant-Colonel, Royal Engineers, and
Brevet-Colonel, of Achalader, Blairgowrie, Perthshire, North
Britain. Improvements in the treatment of fruit and in
apparatus for use therein.

Claims.—(1.) The process of treating fruit by heating the
vessels containing the fruit, and while heating turning the
vessels about one of their axes, substantially as described.
(2.) The process of treating fruit by heating the vessels con-
taining the fruit, and while heating turning the vessels about
their transverse axes, substantially as described. (3.) The
process of treating fruit by heating in a bath the vessels
containing the fruit, and while heating repeatedly turning the
vessels about their transverse axes, substantially as described.
(4.) Apparatus for the treatment of fruit, consisting of a
trough along which traverse carriages carrying frames adapted
to receive the vessels containing the fruit, which frames are
capable of rotation about their transverse axes, substantially
as described and illustrated in the drawings. (5.) The process
of treating fruit, substantially as described. (6.) Apparatus
for use in the treatment of fruit, substantially as described
and illustrated in the drawings.

No. 23826.—2nd December, 1907.—HERMAN LESLIE FINNIS,
of Napier Terrace, Napier, Hawke’s Bay, New Zealand, Sheep-
farmers. An automatic benzine docking and branding iron.

Claim.—The automatic benzine docking and branding iron,
for docking lambs and branding cattle, horses, and the like,
comprising in combination C. Barthel’s automatic benzine
blow-lamp, with a hollow docking-blade, of which one side
is straight to the edge, a hollow branding-iron, both of which
have vent holes suitably arranged in them to let out burnt
gases, and two rods in each to fasten the said iron or blade to
the carrier, the said carrier being suitably arranged to receive
the rods, and to grip them by means of two clamping-screws,
the said carrier being suitably made to have one clamping-
screw above the blow-pipe and one below. The carrier is
suitably bolted to the benzine-container. Both the docking-
blade and the branding-butt are adapted to receive the end
of the blow-pipe in a hole in the butt of each, so the burning
vapours have access straight to the edge of the blade or the
branding-letters. The two irons are interchangeable.

No. 23836.—18th December, 1907.—JOHANNES VALDEMAR
MARTEN RISBERG, of Kanalstrand No. 3, Södertelje, Sweden,
Engineer. Improvements in the method of emulsifying and
making homogeneous milk, cream, or similar liquids, and in
apparatus adapted therefor.

Claims.—(1.) The method of emulsifying and making
homogeneous milk, cream, or similar liquids or liquid mixtures,
characterized by the fact that, after the milk has been led
into a centrifugal drum and the cream has gathered at the
inner surface of the liquid layer, the inner layer (the “cream
zone”) of the liquid is subjected to the action of a suitable
organ, making the same homogeneous at a temperature suit-
able for the process, for the purpose that the greater fatty
particles in the cream zone may be divided to such a degree
of fineness that the particles, owing to their friction surface
increased relatively to the volume of the particles, are carried
away by the serum of the milk, running toward the outlet
opening or openings provided at the periphery of the drum,
so that only milk made homogeneous will leave the drum.
(2.) A centrifugal drum for carrying out the method stated in
claim 1, characterized by the fact that the drum in its central
free chamber is provided with a suitable organ for making
homogeneous the inner liquid layer with the aid of the energy
imparted to the liquid led into the drum and rotating with
the same. (3.) A form of the centrifugal drum stated in
claim 2, characterized by the fact that the centrifugal drum,
provided, if necessary, with a suitable inset for increasing the
effect, has a number of wings mounted at the inner surface of
the liquid in the drum, and partaking in the rotation of the
drum, and with a stationary pipe, which strips off the inner
liquid layer and throws the liquid against the rotating wings
and the liquid surface, the outlet opening or openings for
the liquid made homogeneous being provided at the peri-
phery of the drum, so that insufficiently divided fatty par-
ticles, moved by the power of buoyancy toward the centre of
the drum, do not accompany the liquid leaving the drum, but
are again divided.
