Qualified 'Personnel HE secretary of the 'Fleet Overseas" for British A Street Branch of the British
Makers Legion, Capt, F. D. Bone, has,
in the "Central European Trade Review " for May, which is the official bulletin of the British and Central European Chamber of Commerce, put forward an interesting suggestion. It is to the effect that manufacturers who' may be pondering over the 'difficult question as to who shall represent them in such countries as Albania, Czechoslovakia, ei,reece, Hungary, Jugosla-via, Poland, Rumania, France, Italy and thelf.S.S1R. Should consider the prior claims of British officers and others who 'have been selected by the authorities for special
AIR duties in those countries. Many of them have been able to obtain a thorough knowledge of the lands, peoples and languages where they serve, and have gained cudit for their adaptability and diplomacy. Capt. Bone, suggests that the Association of British Chambers of Commerce might form 'a Committee, including representatives of the Allied Chambers of Commerce and the British Legion in an advisory capacity, which cbuld establish a register of such Seryice and ex-Servicemen with overseas experienc. We understand that attention is being given to this matter.

Curious "Knock" ReL'ouR members of the Coun. sults from Cracked I cil of the I.R.T.E. wereDistributor Cover . recently in the Secretary's car when he complained of a, curi ous trouble that had developed; and as this might just as well occur in a commercial vehicle we are .justified in 'referring to it. When the engine Was running under light load it Operated fairly smoothly, although there was occasional missing, but imme: diatoly the throttle was depressed to an.y considerable extent, a rather rapid and sharp noise of a metallic nature manifested itself. A preliminary " vetting " revealed nothing that could account for the trouble. The " knock," however, .proved to be a series of sharp explosions in the air-inlet of the Carburetter. Fr a time the valves were suspected, but the source was eventually traced to a crack in the plastic cove' of the distributor, this being situated between two of
the pick-up electrodes. When there was only low compression the sparking plugs operated fairly well„ but as compression increased the current chose the easier path through the crack, thus completely upsetting the ignition timing of the two cylinders concerned.
Dustproofing ConCONCRETE can be treated crete by Using 'with chlorinated rubber disChlorinated Rubber . solved in an organic solvent.
The lime in the concrete has no action on it, and the liquid does not penetrate to any appreciable extent, but remains on the surface as a hard, resilient, enamel-like, adhesive filth, filling the holes, Pores, cracks and crevices. Dust-proofing of roads is an application of this liquid rubber, which forms a smooth surface, easily cleaned with soap and water.
