Increase of Miners’ Wages and Coal Prices in France.—
In order to increase the output in the coal mines of the Pas-
de-Calais, the miners have‘ consented to work an extra hour
pef day, and the coal owners have advanced wages by 10
per cent., calculated on the. tonnage output or per hour. To
reimburse the owners for this additional outlay, the Minister
of .Public Works has authorised an advance of 1 fr. per ton
on; the rates previously fixed for the district.

16526 (1915). Improvements Relating to Manipulating
Mechanism for Coal' Gas Generating Apparatus. A. :E.
’ White, of. 88, - 89, and 90/ Chancery-lane, London, W.C.'
• (Communication from Riter-Conley Manufacturing Company,
' of Leetsdale, Pennsylvania, U.S.A.)—Relates to gas gener-
ating apparatus of the kind provided with plugs Or the like,
of heat insulating material, for- closing the retort ends, the
object of- using plugs' being to confine the heat within , the
‘retort, and to prevent losses by radiation through the ■ cast
iron mouthpieces and doors which may be employed in the
retort, the withdrawing and insertion of the plugs being
effected by means of a manipulating device or mechanism.
Fig. T is a side elevation, partly in section, of a bench of
retorts, and the mechanism for manipulating the plugs;
fig. 2 is a face view of the manipulator support; and fig. 3
is a top plan. 2 is the face of a bench through which open
the ends of the retorts 3 formed of refractory material. 4
is the cast iron mouthpiece, and 5 the cast iron door for
the charging end, the mouthpiece communicating at 6 with
the standpipe 7. At the discharging end is the cast iron
mouthpiece 8 and door 9. The bench is closed by a metallic
jacket 10 and an insulating lining 11. Plugs 12 and 13
respectively close the charging and discharging ends, plug
12 being formed with passage 121, through which the dis-
tilled gas may flow to the standpipe 7, whilst plug 13 sub-
stantially ■seals the discharging end of the retort. The plugs
are of refractory material, and their outer faces have a
reduced neck 14, to which is secured the metallic bridle 15,
carrying two upper lugs 16, and the central lower lug 17

for the manipulator. Each manipulator consists of a trolley
frame 21,. having aroller 22, which travels on the upper
face of the track bar 20, and with roller 23 on its under
face. The journal of the latter is eccentrically mounted on
the frame, and can be turned by hand lever 25, thereby, vary-
ing the position of frame 21, and either raising or lowering
the arm 26. At the outer end of the arm 26 are jaws Which
co-operate respectively with lugs on the plugs. With arm
26 presented ; in Towered position to a plug, the tilting of.
frame 21, by turning hand, lever 25, raises the arm into the
full line-position, and engage the jaws with the plug dugs.
The manipulator may be .readily moved on track 20 with
arm 26 projected through the mouthpiece at either , end of
the retort, and thus caused to engage and withdraw the plug,
supporting it in withdrawn.position, and similarly serving to .
re-position the plug when the retort is to be closed. The
mechanism is mounted on a carriage 30,. movable hori-
zontally-across the face of the bench on tracks 31. For
adjusting the manipulator vertically, carriage 30 may sup-
port, the vertical guide :posts 32, on which can slide the
frame 33, with the top transverse bar 34 of the frame con-
nected to the supporting chains 35, which pass around the
elevated sheaves 36, and downwardly to drums 37 on crank
shaft 38, mounted on carriage 30. Bafr 34 of the sliding
frame arid bar 341 provide, a support to which track bar 20 is
pivotally secured at 39, whereby the track and its manipu-
lator, may be swung laterally out of the way when required. -
Secured to the lower end of frame 33 is the operator’s stand
40. (Eleven claims.)

16581 (1915). Improvements, in the Heating of Feed '
Water for Steam Generators. T. Gowans, of 118, Whet-
stone-lane, Birkenhead, Cheshire.—Relates to the heating of

the feed water of a steam generator by means of a pipe or
pipes disposed within and extending through the furnace or
furnaces, the 'feed water being pumped through said pipe or
pipes. The drawing illustrates a double ended boiler of
marine type adapted for the heating of feed, water, in which
the heating pipes are provided with a retarder, a a1 denote
lengths of piping connected together and extending through
'the furnaces b b, each pipe inclining downwardly, from its
respective furnace front c to the bridge foundation d. e indi-
cates a retarder, in which are formed cut-away portions or
recesses e1. f indicates the main feed pipe, which communi-

cates with the furnace piping a a1 by way of valve g, and
down pipe h. On being , pumped through ©aid furnace
piping a a1 the (now heated) , feed water passes through the
ascension pipe if and is delivered to . main / leading to the
generator or generators, vid the valve k. When desired, the
feed may be by-passed through main I by opening valve g
to said main, and closing the ascension pipe i by the valve
k. m indicates a drain pipe leading to the condenser. (One
claim.) • (' " '	.

17405 (1915). Improvements in Steam Condensing Plant.
D. B. Morison, of Hartlepool Engine Works, Hartlepool,
Durham .—Relates to apparatus for withdrawing condensate
with or without condensing water from a main condenser
under vacuum, iand delivering a part or the whole of the
water to one or more auxiliary condensers under a pressure
greater than the pressure in the rnain condenser and less
than atmospheric, and through which auxiliary condenser or
condensers the air .withdrawn from the main condenser is
discharged on its way to the atmosphere. In the drawing,
the condensate is withdrawn from the main condenser c by
a two-stage pump a, b. The first stage a delivers through
a loaded valve d to the second stage b; which discharges to
the atmosphere, and a pipe e iis led from the connection
between the first stage a and the loaded valve d, to two
auxiliary condensers f and g working under different pres-

sures, the resistance to the flow of water through the valve
d being sufficient to cause a preferential supply of water
To the .auxiliary condensers. The water from the auxiliary
condenser f, which is under the lower absolute pressure, is
discharged through a suitably looped pipe h and cock w into
the main .condenser c or into the suction of the first stage a
of the pump, a vent pipe v being provided, so that the air
separated from the water may pass back into the main con-
denser. The condensate from the second auxiliary condenser
g, which is under a higher absolute pressure, is discharged
into the suction of the second stage b. Valves I and m are
provided, for controlling the quantity of water delivered to
the auxiliary condensers, and with the object of preventing
back-flow into the main condenser in the event of derange-
ment, the valve m may be of the non-return type. Two
modifications are described. (Ten claims.)	’

102153. Improvements in Grabs. H. Gillot, ofLand-
straat, JDelfzijl; and I; Roos, of Waterstraat, Delfzijl,
Netherlands.—Relates to a device for locking the slide blocks
in the coupled position, and for releasing them, on single
cable grabs for coals, ores, sand, and the like, more particu-
larly of that type in which the slide block, on which are
mounted the bottom rollers, can be automatically coupled to,

and released from, the slide block provided with a fixed bolt
with a recess, by means of a recessed bolt provided with a
weighted lever, the rods closing the grab, engaging with the
latter slide block. Fig. 1 is a front elevation of the grab
with the .jaws open; fig. 2 is a front elevation of the inner
side of the half B of the upper slide block; fig. 3 is a front
elevation of the inner side of the half A of the upper slide
block; fig. 4 is a plan of the halves A and B of the upper
slide block combined to form one whole. 1, 1 are the two
buckets or jaws pivoted to a crossbar 2 of the grab frame,
and connected by pivoted rods 3 to a connecting part 4 of
sectional or bar iron. The connecting part 4 is secured to
the lower slide block 5. To the lower slide block adjustable
between vertical angle iron ,6 of the frame is secured a ver-
tical bolt 7 fitting into an opening 8 of the upper slide block
9 constituted by two halves A and B (figs. 2 and 3), and,
like the lower slide block 5, adjustable vertically between
the vertical angle irons 6. The slide block 9 is raised arid
lowered by means of cables 14, 15 passing over pairs of
