PROVISIONAL SPECIFICATION.
A Composition for Coating Steam Boilers, Pipes, and other Heated
Surfaces to Prevent 'Radiation:
A communication from GEORGE BROCKLEHURST, of Barbados, Engineer.
I ARTHUR STEPHEN PLEWS of 22 Sackville Street, Manchester in the County
of Lancaster Merchant do hereby declare the nature of this invention to be as
follows:-
This invention consists principally in utilizing for the above purposes infusorial
earth or Barbados tripolite when mixed with water, coal, tar, cement, lime, cowdung,
hair or other fibrous matter either separately or combined and with or without
silicate of soda and calcium chloride.
In manufacturing this composition I reduce the earth to powder, and then mix
the same with cement, lime, cowdung, hair or other fibrous matter, separately or
combined, or with coal tar, and in that combined state it is ready for placing in
casks or other vessels for shipment; and when the composition is required for use,
to bring the same into a fit state and bind it more firmly together it is to be mixed
with water, or with water containing silicate of soda and calcium chloride until it
is reduced to a fit state for plastering onto the surface to be coated.

COMPLETE SPECIFICATION.
A Composition for Coating Steam Boilers, Pipes, and other Heated
Surfaces to Prevent Radiation.
Communicated to me by GEORGE BROCKLEHURST, of Barbados, Engineer.
I ARTHUR STEPHEN PLEW8 of 22 Sackville Street Manchester in the County
of Lancaster Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention consists principally in utilizing for the above purposes infusorial
earth, or Barbados tripolite, when mixed with water, coal tar, cement, lime, cow-
dung, hair or other fibrous matter either separately or combined and with or
without silicate of soda, and calcium chloride.
In manufacturing this composition I reduce the earth to powder, and then mix
the same with cement, lime, cowdung hair or other fibrous matter separately or
combined, or with coal tar, and in that combined state it is ready for placing in
casks or other vessels for shipment; and when the composition is required for use,
to bring the same into a fit state and bind it more firmly together it is to be
mixed with water, or with water containing silicate of soda and calcium chloride
until it is reduced to a fit state for plastering onto the surface to be coated.
The composition may be applied to the surface to be coated by means of an
ordinary mason's trowel in layers of about half an inch thick, and when dry the
final surface should be washed over with water to remove any soluble salts that may
have been formed in the composition.
I wish it to be understood that it is not absolutely necessary to use either the
silicate of soda or the calcium chloride as they are only intended to bring the
composition into a hard mass similar to stone.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
The utilization of infusorial earth or Barbados tripolite mixed with coal tar,
cement, lime, cowdung, hair or other fibrous matter either separately or combined,
and when required for use mixed with water to the consistency of plaster, either
with or without the addition of either silicate of soda or calcium chloride, or both,
substantially in the manner hereinbefore set forth, for the purpose of coating steam
boilers, pipes, and other heated surfaces, for the prevention of radiation.
Dated this 14th day of Antil 1892.
