Plans For The Suppression Of Man-Made Electrical Noises
pLAN.S for the complete suppression of men-made electrical noises which interfere with broadcasting were revealed yesterday in the report of a special committee of the .Institution of Electrical Engineers. The post office and the 8.13. C. were represented on the committee, and the Government is expected to act upon its findings. Tho report recommends that the Electricity Commissioners should be given powers to issue regulations to suppress interference caused both by new and existing; electrical appliances, plant or machinery. They should also have power to require aav scheduled apparatus sold after certain dates to bear a distinguishing mark or guarantee.
The post office, it is recommended, should have power to enforce the regulations subject. to appeal to the commissioners. Noise-producing apparatus is classified in the following main categories:—
Lifts in buildings; Trolley 'busies and trams-, ’ Household electrical appliances
Small electric motors; “.Neon" display signs; Rectifiers for power plant; and Electro-medical apparatus.
Interference must not. exceed in volume one-fortieth of the strength ol ilio received, broadcasting signal. No Army of Inspectors. Ilow the 'regulations would ho applied was explained yesterday by the chairman of the committee, .Mr. C. C. Paterson, of the Institution of Electric a Engineers. He said there would be no army of inspectors searching for trouble. Only when a complaint, was received by the post, office would any action be taken, and ii would be for '-he Electricity Commissioners to decide on Ihc merits of the. complaint. It will be a considerable time —perhaps years—before legislation can be made effective, and tho Institution appeals to the public, to continue the good will on which the post office has based its present work in suppressing interference. Regulations are only required for “refractory oases.” The only type. of interference .which it is practically impossible to stop is that sometimes caused by overhead power linos. Cost, of tilting suppressors is stated in the report to be only a few shillings for small apparatus, but for an electric lift in a block of flats it. would be from £ln to £2!i. IT STANDS TO REASON . . . Pulmonas must kill cold germs more effectively than any liquid remedy taken internally could ever do. As you suck Pulmonas, their highly antiseptic vapours travel along; the airpassages, killing surely and effectively all germs in their track. Danish colds —ward off influenza with IWiimonns —they make the air safe to breathe! Pulmonas at chemists and stores, l/-,i l/'k 2/6.* i
