) is
made in small sizes (6, 8 and 10 litres per hour) for use in vehicular
lamps, under the name of the "Konette," by Falk, Stadelmann and Co.,
Ltd., of London, who also make a number of other small impinging jet
burners. A single jet injector burner on the "Phos" principle is made in
small sizes by the Phos Co., of London, specially for use in lamps on
vehicles.

Nevertheless, although satisfactory medium-sized vehicular lamps for the
generation of acetylene have been constructed, the best way of using
acetylene for all such employments as these is to carry it ready made in
a state of compression. For railway purposes, where an oil-gas plant is
in existence, and where it is merely desired to obtain a somewhat
brighter light, the oil-gas may be enriched with 20 per cent. of
acetylene, and the mixed gas pumped into the same cylinders to a pressure
of 10 atmospheres, as mentioned in Chapter XI.; the only alteration
necessary being the substitution of suitable small burners for the common
oil-gas jets. As far as the plant is concerned, all that is required is a
good acetylene generator, purifier, and holder from which the acetylene
can be drawn or forced through a meter into a larger storage holder, the
meter being connected by gearing with another meter on the pipe leading
from the oil-gas holder to the common holder, so that the necessary
proportions of the two gases shall be introduced into the common holder
simultaneously.
