CAPTURING ENEMY PATENTS.

The following list of British Patents which have been
granted in favour of residents of Germany, Austria, or
Hungary, is furnished in view of the new Patents Acts,
which empower the Board of Trade to confer upon British
subjects the right to manufacture under enemy patents, and
is specially compiled for the Colliery Guardian by Lewis Wm.
Goold, Chartered Patent Agent, 5, Corporation-street,
Birmingham. It is desirable in the first instance to obtain
the latest particulars upon the Register of Patents. If any
patent listed has been assigned to a non-enemy proprietor,
the law does not apply.

27624/11. Discharging retorts. Coke is graded, by being
divided into horizontal layers as it issues from
the retort. Apparatus for this purpose consists
of a trolley running on rails in front of the
retorts, and carrying vertical guide walls of a
height corresponding to the desired thickness
of the lower layer of coke. Above the guide
walls is a transverse deflecting wall which shears
off the upper layer of the issuing cake of coke.
H. Hoppers, Germany (dated June 29, 1911).

28139/11. Coke. Coke and the accompanying by-products
are manufactured from reeds and similar
aquatic plants, by converting the raw material
into briquettes by mechanical means, and sub-
jecting the briquettes to destructive distillation.
P. Hoering, Berlin.

28745/11. Washing ores, etc. In jigs having stationary
screens, the surface of the screens is corru-
gated. K. Schuchard, Germany.

28746/11. Steam generators; water tube boilers. L. Stein-
muller, Germany.

28926/11. Cleaning blastfurnace gases. F. Werndl, Ger-
many.

28985/11. Stoves; furnaces. J. Fuchs, Germany.

29396/11. Furnaces; grates. In a travelling grate in which
the firebars have forked ends to engage the fire-
bar carriers, the portions of the. firebars and
carriers in contact are below their upper sur-
faces, so that cooling is facilitated. F. Kropelin,
Germany.

58/12. Steam generators; locomotive type boilers; fire
boxes. E. Pielock, Berlin.

142/12. Raising and forcing liquids. Apparatus for
raising and forcing liquids containing solids in
suspension, such as mixtures of mud, lime, sand
and water, cement, and the like, comprises a
mixing chamber having a mechanical mixer,
and also a supply of air which further mixes
the material, assists in forcing it along the
delivery pipe, and helps to spray it at the
nozzle. The material is supplied to the .mixer
by any form of pump, air being supplied to
agitate the material prior to entering the mixer.
The controlling valves between the pump and
mixer are automatically operated. J. von
Vass, Germany (dated January 2, 1911).

244/12. Furnaces; indicators. A furnace draught indi-
cator comprises three pressure gauges, which
indicate respectively the pressure differences
between the atmosphere and the chimney, the
ashpit and the chimney, and the ashpit and the
combustion chamber. L. von Lossau, Germany
(dated April 8, 1911).

883/12. Furnaces; discharging. E. Gottlieb, Germany
(dated June 13, 1911).

958/12. Furnaces; steam generator furnaces; grates,
stoking. E. Lochner, Germany.

1160/12. Mine cages. Retaining catches for supporting
mine cages at the pit mouth or at the charging
levels. Mansfeld’sche Kupperschiefer Bauende
Gewerkschaft, Germany (dated January 16,
1911).

1167/12. Valve controlling mechanism for winding gear.
The invention comprises an arrangement of
valves for cage winding gear, whereby either
one valve is closed by the opening of the other,
or independent movement can be given to each
valve, subject to the condition that one is always
returned to the closed position. Provision is
also made for the simultaneous closing of both
valves. Mansfeld’sche Kupperschiefer Bauende
Gewerkschaft, Germany (dated January 16,
1911).

1177/12. Explosives. Dynamit Akt.-Ges., vorm A. Nobel
and Company, Germany.

1338/12. Retort furnaces. C. Roitzheim, Germany.

1458/12. Coke ovens. Each vertical flue in the wall of an
horizontal coke oven is fitted with two nozzles,
the lower determining the amount of gas which
passes to the upper and larger combustion
nozzle. The lower nozzle is thus protected from
the heat and from choking by flakes from the
walls of the flue, and its cross section therefore
remains unaltered. C. Still (firm of), Germany,
(dated January 23, 1911).
