Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 7th January, 1903.

COMPLETE specifications relating to the undermen-
tioned applications for Letters Patent have been
accepted, and are open to public inspection at this office.
Any person may, at any time within two months from the
date of this Gazette, give me notice in writing of opposition
to the grant of any such patent. Such notice must set forth
the particular grounds of objection, and be in duplicate. A
fee of 10s. is payable thereon.

No. 14358.—19th December, 1901.—SVENSKA CENTRIFUG
AKTIE BOLAGET, of Kungsträdgardsgatan 4, Stockholm,
Sweden (assignees of Carl Sigfrid Berghmark, of Birger
Jarlsgatan 11, Stockholm aforesaid, Engineer). A rotating
or centrifugal churn.

Claim.—Rotating or centrifugal churn, provided with a
stationary inset in the shape of a partition or wing, charac-
terized thereby that the inset, which for instance by means
of an arm is attached to vertical rod or pivot extending from
the frame of the churn through the vessel, from the interior
of which it is separated by means of a sleeve or bushing, is
corrugated so as to form vertical or oblique, if preferred
zigzag-shaped, grooves or channels, the inset being, more-
over, set at such an inclination relatively to the axis of the
vessel that the grooves or channels, which preferably have a
sloping position relatively to the vertical, at the rotation of
the vessel direct the liquid particles towards the centre of the
vessel, and thus in a direction opposite to that in which the
centrifugal force acts, in the same time as the liquid
particles at the violent contact with the inset are brought
into a vivid circulation, so that formation of butter is ob-
tained.

dirt, and apparatus for use in connection therewith.*
