113279.' Machines for the Manufacture of > Briquettes.
General Briquetting Company, 25, Broad-street, New York
City.—This invention relates to machines for the manu-
facture of briquettes, and more particularly to machines
or presses for briquetting metal or mineral “ fines ” by
pressure and without the use of a binder of any^kind.
The invention has for its object to provide a simple
machine of the type referred to, wherein the process of
briquetting can be efficiently carried out, capable of
working at low tonnage capacity, and whereby the well-
known advantages of briquetting are brought within the
reach of small foundries and industrial plants ordinarily
incapable of installing and supporting the high capacity
expensive machines heretofore found necessary for securing
proper working. A further object of the invention is to
provide a briquetting ma-chine in which the difficulties
of feeding the material, packing it preparatory to the
use of heavy pressure and removal of the finished
briquettes from the machine, which ordinarily exist in
such machines, are entirely overcome or at least reduced
to a minimum. (Five claims.)

115803 Shovels, Scoops, Spades, etc. J. S. Surbaugh,
808, North 5th Street, Vincennes, Knox County, Indiana.
—The present invention appertains to shovels, scoops,
spades and kindred implements, and aims to provide novel
and improved means for detachably connecting the handle
and blade, whereby such connection can be accomplished
economically and successfully to resist the prying, tor-
sional leverage and other strains to which the implement
, is subjected in'use, and to enable the blade, when worn out
or broken, to be readily replaced l)y another one, using the
same handle, thus enabling the worn out or broken parts
to be readily replaced at less expense to the user. It is
also the object of the invention to accomplish the rigid
attachment of the handle and blade, so that the implement
will be thoroughly practical, economical and feasible from
a manufacturing standpoint, the blade and connection
thereof with the handle being thoroughly substantial and
reinforced to withstand wear and tear. (Eight claims.)

118445. Electric Motors Coupled with Compressors or
Pumps. W. J. Sturgess, 29, Cromer-road, Moseley,
Birmingham.—This invention relates to an improved air
compressor or pump arranged in combination with an
I	electric motor. Previously it has been proposed that elec-

tric motors should be provided with a divided hollow
shaft having a series of vanes formed in one therewith
or attached thereto for the purpose of drawing and
forcing water through the motor. For the purpose of
•	cooling electric motors it has also been proposed to force

cool air into or draw heated air from the interior of the.
motor by means of a pulley having a fan combined there-
with working in proximity to the casing of the motor,
but in such cases the motor has been provided with a
double casing through which the air travels. Electric
motors have also been cooled by means of a current of
air drawn through ducts formed in the partly hollow
shaft of the armature, such armature having a centrifugal
fan fixed thereto, which draws the air through the ducts
and throws it to' the outside of the motor. According to
• this invention the shaft of the motor is formed hollow
its whole length, and the pulley which is mounted upon
its one extremity is provided with vanes which may be
of any suitable shape arranged to act as a fan for the
purpose of drawing or forcing air or liquids through the
whole length of the. motor shafts, or a separate element
may be adapted to fit inside the pulley, said element
having vanes fitted therein, so that it acts as a fan for
the purpose aforesaid. (Two claims.)

118470. Coke Ovens. E. Ore, 11, Rue de la Masse,
Caen (Calvados), France.—In coke ovens for by-products
the heating takes place in heating flues arranged in
the vertical partitions which separate the carbonising
chambers by the combustion of gases developed in the
ovens themselves or outside, which combustion is effected
in air admitted either at the temperature of the surround-
ing atmosphere or previously heated. The ovens are
heated satisfactorily only by producing at will in a given
! zone of the partition the necessary heat, which can be
effected only if simple and easy means are available to
burn at the said point the quantity of gas necessary with
an exactly proportioned amount of air. The present
invention relates to coke ovens characterised by multiple
heating flues in the form of an inverted U, each heated
by a burner which is fed at the desired combustion point
with gas and air supplied in exactly proportioned amounts
under the control of valves or regulators which are
arranged in or operated from circulation galleries situated
outside the fronts of the ovens, the relative quantity of
gas and air respectively necessary for each burner being
ascertained by examining the products of combustion by
means of openings situated in the said galleries, the lower
part of the brickwork of the ovens, situated below the
chambers and partitions, being occupied either by cooling
galleries or by heat regenerators according to require-
ments. (Two claims.)

118522. Distillation of Coal. H. K. Hiller, 39, Victoria-
street, Westminster, S.W. 1.—This invention has for its
object the manufacture of a stable high calorific power
gas suitable for use in internal combustion motors, and
especially those of motor vehicles. Such gas, consisting
principally of methane, will stand high compression with-
out deterioration, and having about 30 per cent, higher
calorific power than the gas from ordinary coal gas works, ,
as now available for such purposes, enables a greater
mileage to be run per unit volume; also, being entirely
free from liquid hydrocarbons at a pressure of 15 atmo-
spheres or thereabouts, will not have any deleterious effect
on gas containers constructed of fabric and indiarubber.

, The gas can be made from the cheapest form of colliery
waste, bastard cannel, coal, lignite, wood, peat, shale or
other suitable material in any of the already known low
temperature distillation systems of either horizontal or
vertical retorts. In all of these systems it has been
recognised that it is advisable to remove the vapours
so distilled from proximity to the hot retort surfaces as
rapidly as possible. By this invention it is proposed, from
the cannel, coal or other material being distilled, to
prepare a gas under considerable pressure as hereinafter
described, which, being discharged into the distilling
chamber in regulated quantities, is by its expansion when
returning to normal pressure, reduced considerably in
temperature, and, mixing with the newly distilled and hot
vapours, they also are cooled and so protected from
cracking or dissociation. The method of preparation is
as follows : Assuming any usual form of retort to be
charged with a gas-making material such as previously
described, and to be heated to such a temperature, say
about 500 degs. Cent, or thereabouts, so that rich hydro-
carbon vapours and gases are being driven off, such vapours
are cooled and condensed in an ordinary type of con-

denser, the vapours beipg then stripped by the well-known
process of oil washing, while the remaining vapours are
compressed in a water-cooled compressor to a pressure
of 15 atmospheres or thereabouts, such compression freeing
the vapours from all easily condensable hydrocarbons,
reducing their specific heat and leaving a practically
permanent gas. This gas, or a portion of it, is returned
to the retort by means of suitable pipes and valves, the
pressure of 150 lb. being maintained right up to its point
of entry into the retort. This point of entry should be
as far as possible away from the general gas exit of the
retort, and just above the layer of material undergoing
distillation if in a horizontal retort. If, however, the
operation is being conducted in a vertical retort, the high
pressure gas pipe should be carried from the top of the
retort centrally through the mass of material to a point
where a heat zone of 500 degs. Cent, or thereabouts is
maintained. The release of the gas at these points has
a two-fold effect. Firstly, the gas expanding from 150 lb.
gauge pressure to normal is reduced in temperature,
owing to the well-known Joule-Thompson effect. Secondly,
the high pressure gas after release and expansion is un-
saturated and in an unstable condition as regards vapour
pressure. Thd liquid paraffinoid hydrocarbons which are
incidentally produced consist largely of compounds of
low boiling point such as pentane and the like^ and are
of high commercial value. (Four claims.)

118546. Electric Fans. The British Thomson-Houston
Company Limited, 83, Cannon-street, London, E.C. (a
communication from the General Electric Company of
Schenectady, New York).—The present invention relates
to air currents producing means in which rotary fans are
arranged to continually change the directions of the air
currents produced. More specifically the invention relates
to an improved arrangement for mounting a plurality of
constantly driven fans to turn or gyrate about a central
support. One of the objects is to produce an arrangement
of fans, preferably a pair of fans, with as few parts as
is compatible with utility and durability, so as to turn
or revolve about the support at a uniform speed. Another
object is to provide means for readily adjusting the speed
of revolution about the supporting member. A further
object is to provide a positive drive for turning the fans
about the support independent of friction and air thrust
on the fans. ♦A still further object is to provide a driving
means that will compensate for any wear and tear or un-
evenness of the driving mains. (Four claims.)

CATALOGUES AND PRICE LISTS RECEIVED.

G. A. Harvey and Company (London), Limited,
Greenwich Metal Works, London, S.E.—Owing to in-
creased costs, the prices of galvanising and of galvanised
iron tanks, etc., have been revised. The new price lists
can be obtained upon application to the firm.

Broom and Wade Limited, High Wycombe.—The con-
nection between Hyatt bearings and efficiency in trans-
portation appliances has already been demonstrated in
practice, and catalogue No. 11 illustrates in detail, with
sectional views, the successful application of the bearings
to trucks, cranes, etc. As is well known, the essential
part of the Hyatt bearing is the hollow flexible roller,
specially prepared and wound helically from a flat strip.
There are two types—commercial and high duty—and in
each case the same fundamental principle is observed. The
sectional views are unusually clear, and they have the
advantage of showing exactly how efficiency is ensured.

American Coal Transport. — Mr. McAdoo, Director-
General of Railways, announced that there would be no
repetition this winter of the traffic delays which last winter
impeded the distribution of food and coal. He declared
that there would be no shortage of coal on account of
any transportation congestion, that there was no dearth
of cars at the mines, and that there would be no undue
shipping delays so long as the essential railroad operatives
remained undrafted.

Spitzbergen Iron and Coal.—The National Tidende says
that an expedition headed by Mr. Salisbury Jones has been
on a visit to Spitzbergen, where the iron and coal fields
belonging to the Northern Exploration Company were
visited by the English representatives. Experts declare
that the iron fields are the most extensive and richest
in Europe, and that there are mountains there consisting
entirely of iron ore. Extensive coal fields have also been
traced.	•	,

Coal Mines Inspection in 1917.—The' Home Office has

August 16, 1918, p. 333): “Delete the word ‘under-
ground, and for ‘ 377 tons ’ insert ‘ 296 tons,’ making
the paragraph read : ‘ The output per person employed in
1913 was 321 tons; in 1914, 290 tons; in 1915, 325 tons;
in 1916, 315 tons; and last year, 296 tons.’ ”
