AN interesting exhibition of applications of infra-red heating by gas in industry is now open in London. It is being held at 1, Grosvenor Place, S.W.1, and has been organized by the British Gas Council.
By infra-red heating, paint can be. dried in a few minutes, instead of several hours. Objects to be dried are passed through a tunnel in which dull metal plates are heated by gas burners to radiate heat. There are two temperature ranges, from 450-650 degrees F. by black emitter panels, and from 1,100-1,800 degrees F. by incandescent sources.
Other uses of the process include the fusing of lettering on sparking plugs and annealing of aluminium pressings.

RADIO CONTROL FOR AMBULANCE FLEET
CONTACT between the control ...station and Guernsey's four ambulances, which are provided by the St. John Ambulance Brigade, is now maintained by V.H.F. radio. This development avoids the need for holding an ambulance in reserve at headquarters for emergency purposes when the others are out.
The installations have been made by the General Electric Co., Ltd., Kingsway, London, W.C.2. The controlling officer's car is also equipped with radio, so that his constant attendance at headquarters is unnecessary.
