Are a scientifically designed packing
of British Manufacture through-
out.

Their quality and efficiency long
known to users everywhere, have
recently received the official recog-
nition of the French Government.
A copy of this report will be gladly
sent on application. Further Speci-
alities S.E.A. Ring Valves and Com-
pressed Asbestos Jointing.



This is a practical device for
colouring the water in a gauge-
glass red, thus enabling the water-
gauge level to be readily seen from
any angle at any height. The
“ Rubygage ’* Indicator can be
attached to any gauge without inter-
fering with the gauge itself.

An Indicator will be sent for 30 days’
Free Trial, on application.



Enables the water level to be main-
tained at its most economical
height, automatically regulating the
check valves as required, and, at the
same time, so controlling the action of
the feed pump that its work is limited
to the exact feed supply necessary.

— If you will write us, we shall be glad to point out to you the benefits
= that accrue from the employment of the “ THERMOFEED ” System.
