sists in confining the coal in an oven, firing the coal,
then introducing into the oven above the coal an ex-
traneously heated deoxygenized blast of a temperature
before its introduction greater than that usually employed
in the coking operation, to increase the heat in the oven
above the temperature produced by the combustion therein
of the gases generated from the coal, and to induce a con-
dition favourable to the rapid generation of such gases, then
introducing a sufficient volume of live air into the oven to
cause the combustion of the combustible gases being evolved,
and then shutting off the supply of live air with the cessa-
tion of the generation of combustible gases to prevent the
combustion of fixed carbon, substantially as described.
(6.) The process of coking coal which consists in confining
the coal in an oven, firing the coal, then introducing into
the oven above the coal a blast comprising extraneously
heated deoxygenized air of high temperature and live air
containing free oxygen, to induce in the oven a temperature
and quality of heat favourable to the simultaneous genera-
tion and combustion of volatile combustible gases, and thus
accelerate the coking operation, substantially as described.
(7.) The process of coking coal which consists in confining
the coal in an oven, firing the coal, and then introducing
into the oven above the coal, alternately and in the order
preferred, extraneously highly heated deoxygenized blasts
and supplies of live air, to regulate and control the coking
operation by adjusting and balancing the temperature and
quality of the heat in the oven at the will of the operator, to
secure the proper relative rates of the generation and com-
bustion of the volatile gases, substantially as described.

12490.—30th March, 1900.—MARTIN KOECK, of Oskosh,
Wisconsin, United States of America, Inventor. Woven
fabric.

Claims.—(1.) As a new article of manufacture, a fabric
composed of stalks of grass twisted together and served to
form a contiuous strand, said strand doubled back and forth
upon itself, such doubled portions being held together by
interwoven binding strands or stays, as and for the purpose
set forth. (2.) As a new article of manufacture, a fabric
the body of which is composed of stalks of grass twisted
together and spirally wrapped to form a continuous strand,
said strand doubled back and forth upon itself, and having
interspersed throughout transverse binding stays or strands
interwoven therewith, such binding strands or stays being
duplicated along the edges of the fabric, as and for the pur-
pose set forth. (3.) As a new article of manufacture, a mat
the body of which is composed of stalks of grass twisted
together and spirally wrapped to form a continuous strand,
said strand bent or doubled back and forth upon itself, and
having interwoven therewith binding strands interspersed
throughout such body portion, and a selvage binding for the
edges thereof, as and for the purpose set forth. (4.) As a
new article of manufacture, a fabric consisting of a main
body portion formed of parallel layers or strands of twisted
grass, each strand being encircled spirally by a thread, in
combination with transverse binding-threads traversing the
entire body but alternately under and over adjacent parallel
grass strands, as and for the purpose set forth.

No. 12491.—30th March, 1900.—THOMAS EDWARD LANE,
of 108, Drayton Gardens, South Kensington, London, Eng-
land, Distiller ; GEORGE THEODORE TEMPLE, of 109, Leaden-
hall Street, London aforesaid, Gentleman ; and JAMES McRAE,
of 7, Fenchurch Avenue, London aforesaid, Engineer. Im-
provements relating to bottles for beer, wine, sedimentary
and other liquids, and apparatus for use therewith.

Claims.—(1.) The combination of a bottle having at the
upper end a perfectly closable and easily adjustable air-inlet,
such as a screw-stopper, and at the lower end an outlet the
interior lip of which is raised to a more or less sharp edge
above the level of the interior of the bottom of the bottle, so
that sediment may be retained in the bottle when the liquor
is drawn off through said outlet upon the removal of the
means for stopping the bottle, and when air is admitted
above the liquor in the bottle. (2.) In bottles and apparatus
of the class described, in combination, a bottle having an
aperture in the bottom thereof closed by a plug or cork,
a holder adapted to clip said bottle, a striking-piece or
hollow plug for forcing the plug or cork into the interior of
the bottle, a washer or the like upon said striking-piece or
hollow plug or otherwise for insuring a tight joint between
said bottle and striking-piece or hollow plug or the holder,
and an outlet in said holder for the purpose of the with-
drawal of the contents, substantially as described and illus-
trated, and for the purpose set forth. (3.) In bottles and
apparatus of the class described, in combination, a bottle
having an aperture in the bottom thereof closed by a plug
or cork, a holder adapted to clip said bottle, a washer for
insuring a tight joint between the said bottle and holder,
and a stand for supporting the holder, the said stand being
