with a little more than the amount of sodium-bicarbonate
that is equivalent to the sodium-sulphide present, and heating
the mixture while steam is passed over it. (3.) The manufacture
of anhydrous pulverulent sodium-hydrosulphide by
passing sulphuretted - hydrogen gas free from oxygen at a
high temperature over finely pulverised sodium-sulphide,
or over the mixture of sodium-sulphide and carbon such as
obtained in accordance with claim 1. (4.) A modification
of the process in accordance with claim 3, in which modification,
when using sulphuretted sulphide containing carbon-
dioxide, as much pulverised caustic lime is added to the dry
pulverised initial products as is required to combine with the
carbon-dioxide contained in the sulphuretted hydrogen.
(5.) The manufacture of pulverulent anhydrous sodium-
thiosulphate by passing atmospheric air (oxygen) at a high
temperature over pulverised anhydrous sodium-hydrosulphide,
nitrogen, free from oxygen, being obtained as a by-product.

No. 24102.—6th March, 1908.—MILDRED BROWN, of 283
Moorhouse Avenue, Christchurch, New Zealand, Widow,
ELLEN ANN BROWN, of 283 Moorhouse Avenue aforesaid,
Spinster, and WILLIAM PERCY ROUGH, of Abel Smith Street,
Wellington, New Zealand, Metaphysician. Improved anti-
rattler for sliding windows and doors of like construction.*

Claim.—Improved anti-rattler for sliding windows and
doors of like construction, comprising roller wheels, each with
a circumferential groove having a rubber ring or tire partially
embedded therein in such position that half the thickness of
the said rubber ring or tire is projecting from the grooved wheel,
such wheels being suitably rotatably screwed to stop-beads
or facing-boards of window-frames in such positions that the
projecting circumferential rounded edges of the rubber rings
or tires are pressing against the window-sashes, keeping them
against the parting-slip, thus preventing the sashes from
rattling, at the same time allowing of their free sliding movement,
up or down.

No. 24164. — 23rd March, 1908. — EDWARD HAMPTON
BROWNE, of Clevedon, New Zealand, Farmer. An improved
wire-strainer.

Claims.—(1.) A wire-strainer consisting of two parallel
bars, connected together at one end with another integral
cross-bar having at one end an integral elongated projection,
each parallel bar ending at the other end in a rectangular
integral bar terminating in an open hook; integral with one
parallel bar near the integral end and parallel with the elongated
projection is a curved projection integral with the bar,
a gap being left between the ends of the hooks for the
admission of the fencing-wire, substantially as set forth.
(2.) The combination and arrangement of parts comprising
my improved wire-strainer, substantially as and for the
purposes specified, and as illustrated in the drawing.

No. 24206.—2nd April, 1908.—THOMAS BOTTRELL, of Amos-
field, in New South Wales, Grazier. Improved apparatus
for facilitating the branding and castrating of calves and
other animals.

Extract from Specification.—An apparatus for facilitating the
branding and castrating of calves and other animals constructed
according to this invention consists of two parts
hinged together, and adapted to be closed up so as to secure
the animal under treatment between them, grasping it by the
neck and by the back portion of the rump. One of these
parts or sides, say the near side, is adapted to be held temporarily
upright to a post or standard, and to be released
therefrom when required. The other part or side, or “ off”
side, has a ratchet passing through and under a pawl upon the
“near” side, so that it may be closed upon its hinge and be
pushed tightly against anything between the upright “near”
side and itself. These sides will hold firmly together until
manually released, and when thus locked together are adapted,
when the stationary one is released from the post or standard,
to have motion through an arc of 90° or thereabouts, so that
the “off” side takes a horizontal position upon the ground.
There is provided upon the “near” side a slide bolt or bar
adapted to secure in a corner one of the legs of the animal,
if necessary, during the castrating operation.

[NOTE.—The above extract from the specification is inserted in place
of the claims.]

No. 24207.—2nd April, 1908.—GEORGE PEACOCK INNES,
of 141 York Street, Sydney, New South Wales, Australia,
Mechanical Engineer, and THOMAS CON ALLEN, of 163 King
Street, Sydney aforesaid, Patent Agent. A variable-speed
and reversible gear for revolving shafts.

Claims.—(1.) In variable-speed gear comprising sun and
planet gear controlled by oil-pumps, carrying the planetary
pinions in a casing which is adapted to rotate around the
central shaft. (2) In variable-speed gear as claimed in claim 1,
reversing the direction of rotation of the driving-shaft by
preventing or partly preventing the rotational movement of
the gear-casing. (3.) A variable-speed gear comprising, in
combination, a driving and a driven shaft interconnected
through sun and planet gearing, controllable pressure pumps,
a casing enclosing the gearing and adapted to rotate around
a central axis, and means for stopping or retarding such
rotational movement, for the purpose described. (4.) The
improved variable-speed and reversible gear, substantially as
described, and as illustrated with reference to the drawings.

No. 24210.—31st March, 1908.—JEAN LEON MULLER, of
Sannois 8 Avenue Berthet, France, Engineer, and JULES
ROUSSET, of Vincennes, 27 Cours Marigny, France, Engineer.
Cinematographic glass plates for projections and method for
manufacturing the same.

Claims.—(1.) A process for the manufacture of cinematographic views on sensitised plates of very fine grain which are
consequently not rapid, consisting in the reproduction upon
the said sensitised plate view by view and with as long a
period of exposure as desired, of a positive or a negative
cinematographic band, by the combination of an ordinary cinema-
tographic apparatus with an apparatus giving the corresponding
displacement of the sensitised plate. (2.) An apparatus
for producing the displacement of the sensitised plate,
and composed of a cam wheel, a frame with tail-piece carrying
pins receiving a reciprocating movement, a plate-holding
frame provided with pins and independent of the apparatus,
a bolt with inclined teeth causing the plate frame to descend
to the extent of a row of photographs at the end of each
travel, and of a shutter with a planet movement. (3.) An
apparatus such as described above, for taking animated pictures
directly, and enclosed in a light-proof casing with a plugged aperture for the passage of the luminous rays to the objective, and with a slot at the lower part provided with a bag for the reception of the exposed plates.
