The gun is operated by a built-in pressure-control regulating valve, and capacity can be varied from 3.5 to 10 c.f.m. Pressure can be reduced to zero if required. thus enabling low- pressure spraying to be carried out with a high-pres- sure supply. A stainless-steel zle gives an finish and uniform material ejection.

DRAWING FILM
Unaffected by Frequent Erasures
EVEN after 25 erasures Velvetex drafting film shows no noticeable loss of "tooth", the makers say. Its sur- face takes pencil or ink and its high translucency and smooth finish make it suitable for high-grade photocopying.
Velvetex is based on a durable and
stable polyester film. It does not tear or crack, will not turn opaque with age, and burns only with dili culty. The surface takes any good- quality waterproof ink without spread and drafting pencils up to 5H.

ACOUSTIC CEILING
P.V.C. Strips Simplify Assembly and Dismantling
USE of flexible p.v.c. strips instead of aluminium in the Metacoustic ceiling has simplified assembly and dismantling, so that no nuts, bolts or rivets are needed. It is now possible to erect a directional strip ceiling without transverse joints, which com- pares favourably in cost with square tiles.
Galvanised primary channels are suspended at 5 ft. centres, and pun- ched angles on 2 ft. centres are con-

FIXING TOOL Operator can Exceed 200 Fixings per hr.
USING THE Ucan Komet cartridge fixing tool, an operator can safely and easily drive over 200 fixings an hour into steel, concrete or masonry.
Automatic cartridge rejection re- duces operating time and increases safety. Safety is further ensured by a device that prevents the trigger from being pulled unless the breech has been locked and the barrel firmly pressed against the fixing surface, and also by a shield fixed to the tool.
In addition to a 1⁄4 in. barrel, 5/16 in, and 4 in. barrels are available
