No. 27029.-10th December, 1909.—AMERICAN AUTOMATIC
TELEPHONE COMPANY, a corporation of the State of New
York, with an office at Rochester, County of Monroe, in the
State of New York, and also an office and place of business
at Urbana, in the County of Champaign, State of Ohio,
United States of America (assignees of Charles Lane Goodrum,
of Urbana aforesaid, Electrical Engineer). Controlling-
mechanism for progressively movable electric switches and
other devices.

Extract from Specification.—This invention relates to electric
switches and other devices which are operated progressively,
and it has for its object to provide an improved mechanism
for controlling such a device, whereby it may be operated a
predetermined number of times, arrested and subsequently
restored, the parts of which are so arranged for conjoint
action that the device when arrested at the desired point is
incapable of a further advance movement until it is restored.
This invention is related more specifically to the art of tele-
phony and those switches employed in making the connections
between the telephone lines of automatic telephone-exchange
systems, and its further object is to provide in connection with
such switches a motor and release devices which may alternately
be rendered operative to set the switch in a desired position
of adjustment and subsequently restore it. The devices con-
trolling these parts, as comprehended by this invention, are
designed to be actuated by instruments on a telephone-line,
and to control the movement of the motor device so that it
may be actuated one or more times by one or more impulses
of current transmitted successively over the telephone-line
and then arrested and rendered inoperative or unresponsive
to further impulses, said mechanism then rendering the
releasing-devices capable of operation and permitting their
actuation when it is desired to restore the switch to its normal
position. To these and other ends the invention consists in
certain improvements and combinations of parts.

No. 27037.—14th December, 1909.—JOHN WILSON, of 46
Market Street, Ulverston, Lancaster, England, Tobacconist.
Improvements in connection with the utilisation of the
vapours or gases derived from liquid fuel in the heating of
steam-boilers and the like.

Claim.—In the utilisation of the vapours or gases derived
from liquid fuel in the heating of steam-boilers and the like,
a process wherein, firstly, the liquid fuel is imperfectly
vaporised—that is, reduced to vapour—and the process of
vaporisation not carried appreciably beyond the stage at which
conversion into vapour takes place; secondly, superheated
steam is introduced into such vapour, the resulting mixture of
vapour and steam passing into a heated mixing-coil or chamber
where the vaporisation or gasification is completed; thirdly,
the said mixture passes through an induction-tube, or its
equivalent, where it mixes with or takes up air; and, fourthly,
the said mixture of combustible gas and air is delivered in a
mixed condition to the burning point or points at which com-
bustion takes place.

No. 27038.-14th December, 1908.—ALEXANDER ALBERT
HOLLE, of Haere House, Olst, Holland, Gentleman. Im-
provements in steam and other fluid turbines.

[NOWE.-This is an application under the International and Inter-
colonial Arrangements, the date given being the official date of the
application in Great Britain.]

Claims.—(1.) A steam or other fluid turbine in which the
steam or other fluid is admitted intermittently and momen-
tarily, so that it acts on the vanes by impact or impulse only,
and not by either pressure or expansion. (2.) In a steam or
other fluid turbine as specified in claim 1, arranging the
exhaust ports so that the vanes open them immediately after
the admission-valves are closed, as and for the purpose set
forth. (3.) In a steam or other fluid turbine as specified
in claims 1 and 2, maintaining a vacuum or negative pressure
at the exhaust ports, as and for the purpose set forth.
(4.) The improved steam or other fluid turbine substantially
as described, and illustrated by the drawing.

No. 27039.-14th December, 1909.—EDWARD MORTEN
HOLME, of Beech House, Adswood Lane, Stockport, Chester,
England, Assistant Dock Superintendent. Improvements in
electric cranes.

Extract from Specification.—According to this invention, in
order to control the working of the electro-motors used to
effect the movements requisite in the working of a crane,
there is provided for each motor, or, if desirable, for two or
more of the motors of the crane, a controller in which contact-
devices or other circuit-closing devices, operated separately
or moved two or more together, are put into and out of use
so as to close circuits, and to cut out resistances in proper
order as may be necessary, by means of a solenoid or electro-
magnet, or solenoids or electro-magnets, and brought into
action or moved by means of controlling or operating devices
provided in a portable apparatus, either adapted to be carried
wholly or in part by the operator, or to be placed in different
places for use at different times. And the connection be-
tween the controller of the motor or motors and the con-
trolling or operating devices is made by means of flexible or
jointed conductors for electric currents, so as to make it easy
for the operator to carry about the whole or part of the
controlling or operating devices, as the case may be, or for
such controlling or operating devices to be moved into different
positions from time to time.

of the claims.]

No. 27040.-15th March, 1909.—ALBERT KILBORN, of
“Bondi,” New Street, Middle Brighton, Victoria, Australia,
Engineer. Improvements relating to the milk-delivery pas-
sages of milking-machines.

[NOWE.—This is an application under the International and Inter-
colonial Arrangements, the date given being the official date of the
application in Australia.]

Extract from Specification.—The base plate 1 of the pul-
sator, which forms the lid of the bucket 2, is provided with
duplicate castings 3, 3, valve-chambers, or the like, each
having two open-ended passages 4, 5, formed therein and
extending at right angles to and in communication with each
other. The milk-discharge passages 5 communicating with
the milk bucket or receiver 2 are tapered as shown, and are
provided each with a removable tapered plug 6 formed with
a longitudinal passage 7, communicating, when turned, by a
lateral opening 8 with the lateral passage 4 of said casting.
The lower end of said plug projects some distance through the
milk-discharge passage and below the under-surface of the
base plate 1 of the pulsator. The other passage 4 of the
casting is fitted with the milk-pipe 9 to which the flexible
milk-tube 10 is attached. The milk-delivery passages 5 and
the cock which is formed by this construction may thus be
readily cleaned when the plug 6 of the latter is removed.

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