No. 20628, 24th January, 1906.—JAMES PALMER CAMP-
BELL, of Wellington, New Zealand, Solicitor (nominee of Ru-
dolf Braun, of 68 Seymour Grove, Old Trafford, Manchester,
England, Electrical Engineer). Improvements in means for
automatically equalising the load in alternating electric-
current circuits.

Claims.—(1.) An apparatus for equalising the load on an al-
ternating current-supply circuit, comprising two asynchronous
machines, the rotors of which are mechanically coupled
together and provided with a fly-wheel, the secondary winding
of the first machine being electrically connected to the primary
winding of the second machine, automatic means being pro-
vided whereby one or other of the secondary windings is short-
circuited or closed on itself through a resistance so as to vary
the speed of the apparatus according to the amount or charac-
ter of the load on the supply-circuit. (2.) For an equaliser
of the kind described, means for varying the resistance con-
nected to the secondary windings of either machine, com-
prising a plurality of vanes electrically connected together,
and mounted on a shaft which can be rocked in either direction
so as to cause the vanes to dip to a greater or less extent
into two sets of insulated tanks containing water or other
suitable liquid, one of the said sets of tanks being connected
to the secondary winding of the first asynchronous machine,
and the other set to the secondary winding of the second
asynchronous machine, substantially as described. (3.) For
an equaliser a regulating rheostat of the kind described,
provided with means for automatically varying the resistance
connected to either of the secondary windings of the two
asynchronous machines, comprising two induction motors
with opposing torques, the rotors of which are connected
to the shaft of the rheostat, one of the primary windings
being operated through series transformers by the current
in the supply-circuit, and the other primary winding being
connected through shunt-transformers across the supply-
circuit, substantially as described. (4.) A modification of
the arrangement for automatically operating the regulating
rheostat, in which the induction motor connected across the
supply-circuit is replaced by an adjustable spring or weight,
substantially as described.

Improvements in vehicle-balance adjustment means.

Claims.—(1.) In vehicles, to allow of adjustment by longi-
tudinal movement of the body thereof, means comprising an
apertured or recessed bar or the like, locking means there-
into, the said means being connected to the body or a housing
on the body, a lever having an end adapted to engage
the apertured or recessed bar, and open the locking means
and move the body, substantially as described. (2.) In
vehicle-body adjustment means, a pivoted foot having a
locking-lever substantially as described. (3.) In vehicle-
body adjustment means, a pivoted foot, in combination
with a housing substantially as illustrated in Figs. 3 and 4.
(4.) In vehicle-body adjustment means, a housing to be
attached to the body, and be located below it, constructed
substantially as described. (5.) In vehicle-body adjustment
means, a lever substantially as described in combination with
an apertured or recessed member located under the body as
described. (6.) In vehicle-body adjustment means, the com-
bination as a whole of the parts described, which are illus-
trated in Fig. 1. (7.) In vehicle-body adjustment means, the
combination as a whole of the parts described, which are
illustrated in Fig. 5.

of 71 Albany Avenue, Toronto, Ontario, Canada, Machinist.
Improvements in or relating to loose-leaf binders.

Extract from Specification.—This invention relates to a loose-
leaf binder, comprising in its construction a binder-back con-
sisting of a stationary member and two laterally movable
members located at opposite sides of the middle of the
stationary member, an operating screw mounted in bearings
connected to the inner face of the stationary member and
parallel with the edges thereof, two wrist-plates pivoted
within the binder-back on a line parallel with the longitudinal
axis of the operating screw, a slide-nut movable on the
operating screw, a connecting-lever having at its middle a
pivotal connection with the slide-nut and at its ends pivotal
connections with the wrist-plates whereby it will oscillate
them during the movement of the slide-nut, and two links for
each wrist-plate having their inner ends pivotally connected
to the wrist-plates on a line passing diametrically through the
wrist-plate pivots and on opposite sides of and at the same
distance therefrom and having their outer ends pivotally
connected to the movable members on lines passing dia-
metrically through the wrist-plate pivots at substantially
right angles to the longitudinal axis of the screw, whereby the
links of each set may move in substantially parallel planes
during the oscillation of the wrist-plates, and during said
movement constantly exert their lines of force on said movable
members at substantially right angles to the length of the
screw, as more fully set forth and more particularly pointed
out in the claims.

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

No. 20637.—19th January, 1906.—FRANK VICTOR RAY-
MOND, of Invercargill, New Zealand, Solicitor. Improved
hair-curler.

Claim.—In a hair-curler in combination, a holder having an
upturned end formed with a large eye and an upturned end
formed with a small eye, and a curler having a head and
tapering spring prongs, the prongs being one longer than the
other and adapted to pass through the large eye of the holder,
so that only the longer prong extends into engagement with
the small eye of the holder.

Claims.—(1.) In a steam turbine having vane wheels
mounted with side faces thereof in proximity and forming an
interspace, a steam inlet at the central portion of the inter-
space, opposing sets of vanes projecting from the opposite

and the vanes longer at the peripheral than at the axial por-
tions of the opposing wheels, for the purpose stated.
(3.) In a steam turbine having vane wheels mounted upon a
separate revolvable shaft, the vane wheels having side faces
