THE COLLIERY GUARDIAN.

June 21, 1918.

THE FREIGHT MARKET.

Outward chartering on the north-east coast has been
exceedingly slack during the past week—only four fixtures
being reported. Of these, one is“ for Tyne loading to
Helsingborg at 205 kr., one from Tyne or Wear to Stock-
holm at 207ikr., one from Blyth to Gothenburg at 2O7| kr.,
and the fourth from Glasgow to Barcelona at 400s. These
are all very high rates equalling, indeed, previously estab-
lished records. At present, little business other than
Swedish is being entertained at all—Sweden being the only
direction from which tonnage is being sent forward at all
freely. Even Swedish business is sorely hampered by
reason of the scarcity of “free” coal and the congestion of
prompt loading turns. For all other destinations, although
there is any quantity of chartering on offer, nothing is
doing, by reason of the facts of the scarcity of coal and the
very limited amount of shipping which these neutral
countries are prepared to place at our disposal. • Rates for
these other directions are nominally as follow:—Bilbao or
Santander, 300s. to 310s ; Lisbon, 115s.; Oporto, 125s.;
Gibraltar, 100s.; Port Said, 200s.; Barcelona, 440s., and
Huelva, 420s.—all for Tyne loading. It is long since most
of these rates have been tested by actual transactions. At
South Wales, business done has been mainly for French
Atlantic destinations at scheduled figures ; but noteworthy
fixtures elsewhere include Casablanca at 160s., Gibraltar at
100s., and Huelva at 400s. Tonnage is offering for Spanish
ports at about recent figures, but licences for shipment in
neutral directions are difficult to obtain, owing to the
shortage of coal.

Homewards, River Plate rates are unchanged at 225s. to
the United Kingdom, and 250s. to Western France.
Virginia coal freights are maintained at 80s. to the River
Plate and 84s. to Brazil. Grain rates at the United States
of America are firmly held. At the Far East, there is a
brisk demand for tonnage at high figures. Mediterranean
and Bay ports are taking up ore and phosphate vessels at
full rates for Allied destinations.

Canada’s Coal Shortage.—In consequence of the coal
difficulties in the United States, some fears are entertained
in Canada regarding the quantity of fuel which may be
allotted to the Dominion next winter. Some of the Parlia-
mentary representatives pressed the following points upon
the attention of the Government: The desirability of en-
couraging the development of Canadian bituminous and
anthracite coal; utilisation of peat and lignite deposits;
conservation of natural gas; development of water power
in order to economise coal; reduction in the overhead
charges of collieries; improvements in mining machinery
in Nova Scotia; the compulsory spending of excess profits
in improving mines; the removal of restrictions on imports
of mining machinery; the abolition of the duty on coal,
and the appointment of an energetic man as “ speeder
up.” On behalf of the Government it was stated that
the Coal Controller’s principal aim was to make sure
of obtaining the allotment of 16,000,000 tons of coal from
the United States, and to arrange for equitable distribu-
tion. If things went ordinarily well, the allotment would
be received as usual.

ABSTRACTS OF PATENT SPECIFICATIONS
RECENTLY ACCEPTED.

115288. Centrifugal Compressors or Pumps. C. C.
Wood, 63, Norfolk-street, Sheffield.—This invention relates
to centrifugal compressors or pumps, and is equally applic-
able to air or gas. One of the methods at present adopted
for raisihg air to a relatively high pressure is to employ
a series of fans, arranged on one common shaft, through
which fans or impellers the air passes in stages, the pres-
sure obtained being increased by each successive impeller.
Such an arrangement is necessarily expensive, since it
entails the employment of a series of fans. This inven-
tion accomplishes with one fan what has previously necessi-
tated the employment of several fans, and consists in an
improved method of compressing air or gas by re-circulating
a continuously increasing quantity of such air or gas
through the same centrifugal compressor or pump circuit,
the outlet of which remains closed until the desired pressure
has been attained; another feature of the invention is the
improved combination and arrangement of compressor plant
to attain the above-mentioned object. (Two claims.)

115316. Furnaces .or Kilns for Calcining Refractory
Materials. E. J. W. Richards, 90, Mitchell-street, Glas-
gow.—This invention has reference to improvements in
and relating to furnaces or kilns for calcining limestone,
fireclay, silica, magnesia, limestone, dolomite, bauxite, and
like refractory materials. The furnaces or kilns are formed
of rectangular or other suitable shape with hinged or other
doors on top through which the refractory material and
combustible coke would be fed ; and with hinged or other
doors for removing the concentrated material at the
bottom, and “poking” doors at the sides and ends; and
with walls of reinforced dolomite or other suitable material,
all much of a usual construction. This invention consists
in providing such furnaces with a flue or chamber, of
triangular or equivalent shape in cross section, arranged
centrally along the bed of the furnace, and extending from
end to end of same. The sides of this flue are provided
with holes and air forced into the flue passes out through
the holes into the material being calcined.

115354. Calorimetric Meters. A. Guillemin, 21, rue des
Mines, Audincourt, Doubs, France, and Compagnie des
Forges d’Audincourt et Dependances, Audincourt, Doubs,
France.—It is of practical utility to be able to determine
at any given moment the amount of heat set free or
retained by a fluid, liquid or gaseous mass having passed
through a pipe or an apparatus in a given time. Deter-
minations of this kind would be especially useful in the
case of boilers, engines, or other steam apparatus as well
as for heating plants and for hot water preparing and
distributing plants. Installations for heating or for hot
water supply are often adapted to be used in common by
the occupants of the same building or in other cases are
established for a group of buildings or for a city district,
and by the use of a device which allows of measuring the
number of calories set free by the fluid passing through
the various apparatus, it will be an easy matter to divide
the different expenses for combustible and the like among
the different consumers, and this exactly according to the
amount consumed in each case. Such a distribution of
expenses is, in fact, the only proper one, and is the method
commonly employed in city water, illuminating gas and
electric current supply systems, therefore its use is also
desired for the numerous applications of steam, hot water,
and hot fluids in general. However, it is evident that
such result could not be obtained by the use of an ordinary
meter which indicates simply the volume of flow without
taking account of the temperature or density. The object
of the present invention is to provide a calorimetric meter
so designed as to afford a complete solution of all pro-
blems connected with measurement of volume, tempera-
ture, rate of flow and amount of heat in the case of hot
fluids. (Eight claims.)

115385. Lifting or Hoisting Apparatus. H. J. Munro,
Uplands, Pontardawe, Glamorgan.—This invention relates
to apparatus in which the load is lifted by compressed
air. It has for its object to provide improvements in
lifting or hoisting apparatus in which the load is lifted
pneumatically, whereby the load is, when raised, held sus-
pended and is lowered independently of the means by
which it was raised. The suspensory and lowering medium
employed is an incompressible fluid, such as oil or water,
hereinafter referred to as oil, and the combined suspensory
and lowering medium comes into action automatically at
any point in the lifting of the load, whether the supply
of compressed air be cut off or fail. The invention com-
prises a lifting or hoisting cylinder and piston having
means for the introduction of an operating fluid, such as
steam or compressed air, and a suspensory and lowering
cylinder and piston, filled on both sides of the piston
with an incompressible fluid, such as water or oil, and
having two valve-controlled conduits connecting the two
sides of the piston, one valve being an automatic non-
return valve, and the other a valve operable at will, of
means connecting the two pistons so that they move
together, such as piston rods connected by a cross piece,
the arrangement being such that when the lifting piston
is acted on pneumatically to raise the load the suspensory
and lowering piston moves therewith and fluid is forced
through the connection containing - the automatic non-
return valve, into the suspensory and lowering cylinder
below its piston and is there retained to act as a suspen-
sory medium until the valve in the other connection is
opened, whereupon the oil passes back to whence it came
and the load is lowered. Preferably, the cylinders are
arranged the one within the other concentrically, one
piston comprising a ring moving in the annular space
between the inner and outer cylinders. Further, one of
the valved conduits connecting the two sides of the piston
in the suspensory and lowering cylinder may be formed
through the piston. (Six claims.)

115555. Ventilating Pipes for Colliery Purposes.
W. P. Wrightson, 14, Church-road, Penarth.—This in-
vention relates to improvements in the construction of
pipes composed of thin sheet metal such as are employed
as ventilating pipes or for equivalent purposes in collieries
and suchlike places in which a continuous communication is
provided by interconnecting adjoining lengths of pipes
by fitting the end of one into the end of that next con-
secutive thereto. In such pipes very thin sheet metal
would suffice to enable the pipes to withstand the working
pressure of the fluid conveyed therein, but to enable the
pipes to resist local deformation at the extremities where
they are required to fit one another in an air-tight manner,
according to the usual method of construction, it has, in
practice, been found necessary to use sheet metal of undue
thickness, involving with unsatisfactory results, un-
desirable weights and cost of the range of pipes. The
present invention provides local strength and stiffness to
preclude deformation by providing a unit length of pipe
made up of three metal sheets riveted or brazed together,
and near one end of each pipe a ring corrugation is formed,
but leaving a sufficient tapered length between the said
ring and the extremity of the pipe, and near the other

end of the pipe ring corrugations are formed below the
tapered extremity of the socket for the spigot connection,
thus providing the necessary strength and stiffness to
prevent deformation. (Two claims.)
