ROADMENDER

AND NOISE

"The recent regulation, an im- portant public amenity, made by the Minister of Transport, pro- hibiting the use of motor horns during certain hours, has, direct- ed attention to the possibility of reducing other street noises; and 'a Committee has been appointed to study the question in so far as It relates to noises made by motor vehicles. It has been pointed out by various writers in the Press... however, that cars and lorries are by no means the only offenders in the matter of noise, and that pneumatic tools employed on road-repair work, in particular, create a barely-tolerable din while they are in use. So far, no practicable suggestion has been made for eliminating the metallic sound of the piston striking the arivil in such tools, but actually this is comparatively unobjection- able, the majority of the noise being produced by the exhaust. It might be thought at first sight that

efficient the design of an silencer for the exhaust air would offer no particular difficulty but a consideration of the conditions to be met show that the problem is by no means a simple one. Briefly, while being sufficiently strong as to preclude any pos- sibility of bursting or becoming damaged in rough handling, the the weight, size and shape of suleriter must not inconvenience the operator. It must reduce the noise to the required degree with- out increasing the back pressure to an appreciable extent, and, fin- ally it must be low in cost, with a simple and reliable method of Axing.

TRADE-MARK

RULING

Nanking. Oct., 13.

An important ruling regarding the use of Chinese trademarks on foreign goods is laid down by the Ministry of Industry.

In an inquiry to the Ministry the Shanghai City Chamber of Commerce asked if it was permis- sible for merchants to apply for 3 trademark for a certain kind of product. and then apply the trademark to similar goods im- ported from abroad.

Return To Coal

"Several

American stearnship operators are considering a returni to the use of coal as a result of the price of fuel oil" declared Mr. R. J. Baker, president of the American Steamship Owners As-.. sociation, in a protest filed with the Petroleum Administrative Board against the rapidly mount- ing cost of all, which, he added. had risen to more than 100 per cent above the 1932 price.

'He said that the American mer- chant marine, perhaps the great- est consumer of American oil," is unable to raise its rates to offset. the increasing cost resulting from fuel prices, and that this cost adds another item to the total of disid- vantages under which the Amert- can merchant marine operates in -competition. with countries of io-

wer original costs maintenance.

Mr. Baker also said that for the first time in many years American ships are being offered foreign oll at prices below those quoted at New York.

*Fuel oil in 1932," he said, "sold at 60 cents a barrel Congress in the Revenue Act added a duty of one-half a cent per gallon, or 21 cents a barrel. That brought the price up to 81 cents. Under the recovery programme the price has steadily increased to the present "level of $1.30 a barrel. Freight meanwhite has fallen off at an alarming rate, and passenger travel has, until recent months, also shown a decrease."

SCIENCE IN BUILDING

While the design of most build- Ings is the function of the archi, tect and their construction that "of the bullder along with the attendant trades of joiner, plas- terer, painter,

Sometimes, as in a structural steel building, he is even more directly concer- ned. He has increased the capa- city of both architect and builder the pro- by his machinery for duction of bricks and tiles, of cement and concrete, and for the quarrying and dressing of store. It should not be overlooked, therefore, that, though an count of the International Build- ing Trades Exhibition, which was held at Olympla from September 12 to 26. may at first ŝight up- pear rather alien matter for these pages, there is a definite amount of engineering Interest in that exhibition.

-Even If ship owners were able to increase rates, such a would be contested by exporters and importers in this country, Mr. Baker declared, adding that he did not belleve that "the cause of... orderly recovery, can possibly be served by spectacular and unjusti- fled increases in the price of a single commodity. The Presid- ent's compaign to raise prices, I am sure, did not contemplate such procedure."

Mr. Baker said operating costs had been raised under the NRA and through the adoption of other codes, and predicted that the de- mands of labour would bring about a further burden.

For Reconnaissance And Ratrol Duty

A squadron of ten Avro (Type 626) military biplanes, left Lympne aerodrome, Kent, in for- mation recently on the first stage of a fight to Egypt, where it will be added to the strength of the Egyptian Army Air Force.

A first squadron of similar air- craft flew from England to Egypt towards the end of last year and they have since been engaged in important patrol-and reconnais- sance cuties, directed to preserve the integrity of the frontier against the efforts of contraband smugglers, and in aerial survey .work.

The Avro 020, powered with a Siddeley Cheetah 277 h.p., radial. air-cooled engine, is an admirable vehicle for the building up of a young air force. It is economical, yet efficient.

Each machine in the Egyptian service is equipped for the per- formance of a variety of duties, including aerial photography, rẻ- connaissance, light bombing and machine-gunning. Similar air- craft are at present used by the air forces of Chius, Argenting and Belgium, and in Scandinavia. Or-· ders are pending from other coun- tries.

Two Royal Air Force officers who have been seconded for duty with the Egyptian Government are in charge of the new force.

Both are with the squadron now. on its way to Cairo. They are Kalmakam Talt Bey and Bim- bashi Webster, the latter famous, as the winner of the Schneider Trophy contest at Venice in 1927. With them is a party of Egyp- tian officer pilots and British and Egyptian non-commissioned of- Асеть.
