employment of wash waters by admitting same under pressure
in a vat below such ores or their compounds, substantially
as described. (2.) In the decantation of cyanide and like
solutions contained in crushed ores, pulp, sands, or slimes,
a process of separating solutions or solvents containing
precious metals, and particularly gold and silver, from ores
and their compounds, which consists in agitating mildly a
mixture of such ores and such suitable solvent in a vat having
a filter-bed bottom beneath and through which wash is admitted
under pressure, substantially as described. (3.) In
the decantation of cyanide and like solutions contained in
crushed ores, pulp, sands, or slimes, a process of separating
solutions or solvents containing precious metals, and particularly
gold and silver, from ores and their compounds, which
consists in forcing such solutions out of such ores by substituting
therefor wash waters introduced [for such purpose
underneath such ores or their compounds under pressure,
substantially as described. (4.) The improvements in the
decantation of cyanide and like solutions contained in crushed
ores, pulp, sands, or slimes, substantially as and for the purposes

No. 20641.-25th January, 1906.-ROBERT AUGUSTUS
CUMMINGS, of Third Street, Beaver, Pennsylvania, United
States of America, Civil Engineer. Reinforced concrete
column.

Extract from Specification.-The present invention has
for its object a number of improvements relating to columns
of this class. One of these improvements is to provide an
improved means which can be applied at the place of building
for uniting ends of the strips to form the continuous bands;
another improvement is to provide means for holding the
bands against either downward or upward movement, so that
they will always extend in a straight line transversely of
the column, and their efficiency be a maximum; a further
improvement is to provide means for holding the metallic
members—that is, the vertical members— and transverse bands
properly spaced from the casing, so that said metallic members
will be uniformly distributed in the concrete and entirely imbedded
therein; a further improvement consists
in providing vertical reinforcing members having a cross
section in which the metal is so distributed that the major
portion thereof is as far removed as possible from the centre
of the column, thus increasing the radius of gyration and
correspondingly increasing the stability of the column.

of the claims.]

No. 20700.-10th February, 1906.-FRANK JOHN EDWARD
SMALLBONE, of Invercargill, New Zealand, Engineer. Improved
means for cramping picture-frames or other mitred
joints.*

Claims.--(1.) For the purpose indicated, the general arrangement
and combination of parts in my improved cramp for
picture-frames and other mitred joints, substantially as described
and as set forth. (2.) In a cramp for the purpose
indicated, the combination with a rectangular base-plate
in which are two slots of eccentrically mounted plates with
serrated edges adapted to slide in the slots, and means for
causing the serrated edges of the plates to grip the picture-
frame, substantially as described and as shown.

No. 20720.-14th February, 1906.-WILLIAM MILLER
DAVISON, of Government Road, Port Pirie West Extension,
Port Pirie, South Australia, Australia, Engineer. An improved
device for vending measured quantities of liquid and
for recording the number of measures sold.

Extract from Specification.-My device consists essentially
of a measuring plug or chamber fitted within a body or case,
at one end of which is a registered mechanism operated by
the movement of the measuring plug or chamber. The body
has on one side a tubular inlet projection whereby it is fitted
to the neck of the bottle, the barrel, or other liquid-containing
vessel, and has on the other side an outlet-spout from which
the liquid is delivered into the glass or other receptacle.

of the claims.]

No. 20721.-14th February, 1906.-WILLIAM MILLER
DAVISON, of Government Road, Port Pirie West Extension,
Port Pirie, South Australia, Australia, Engineer. An improved
pump for vending measured quantities of liquid and
for recording the number of such measures sold.

Extract from Specification.-My invention relates to what
are commonly known as "beer-pumps" or "beer-engines,"
and consists essentially of a special construction of pump and
two-part piston-rod therefor, and of a registering-mechanism
mounted upon or contained in such rod, with means whereby
the registering-mechanism is operated each time the pump
is operated. My improved pump is attached beneath the
counter in place of the pump now used, and the same arrangement
of handles and pipes as are now used may be retained.
It may be constructed of suitable size to measure and register
pints, butchers, or glasses of any size that may be desired.

of the claims.]

No. 20731.-7th December, 1905.-THOMAS CARTER, of
Mirboo North, Victoria, Australia, Farmer. An improved
cream and milk cooler and aerator.

Claims.--(1.) In an improved cream and milk cooler and
aerator such as d, formed with V-shaped sides having semicircular
openings on their lower edges, and comprising a
water-chamber such as d1, substantially as set forth and
described, and illustrated by the drawing. (2.) In an improved
cream and milk cooler and open trough such as c,
with perforations at the bottom such as f, substantially
as set forth and described, and illustrated by the drawing.
(3.) In an improved cream and milk cooler, the two water-
jackets such as a and b arranged to form a space between
them through which the milk or cream to be cooled is passed,

No. 20741.-17th February, 1906.-JAMES THOMAS
HUNTER, of Queen's Chambers, Wellington, New Zealand,
Registered Patent Agent (nominee of Harry Shoemaker,
of Jersey City, New Jersey, United States of America).
Improvements in receiving-apparatus for use in wireless signalling
and like purposes.

Extract from Specification.-More particularly, my invention
resides in a detector or wave-responsive device employed
in such receiving-apparatus. This detector or wave-responsive
device may be described as a primary cell in which
one of the elements is extremely small, or rather has extremely
small area of contact with the solution or excitant of the
cell. Such detector is responsive to the feeblest electrical
disturbances, and is, in fact, much more sensitive than the
detectors, consisting of a very small polarization-cell, in which
the anode has very small area of contact with the electrolyte.
With these polarization-cells a local source of energy is required,
whereas with the primary-cell detector described the
local source of energy common in wireless-telegraph receiving-apparatus
is entirely dispensed with. My galvanic-cell
detector is therefore clearly distinguished from electrolytic
or polarization devices or other forms of detectors requiring
an associated source of energy. My in-
