20 The Industry Metal Melting Furnaces Practical Features of Manometer Production IN particulars supplied by the Mono-meter Manufacturing Co., Ltd., their latest pioduct is described as a 600- i,5oolb. brass capacity preheated air, true-lip, axis-tilting, furnace. From the illustration it will be seen that th" furnace is raised or lowered by the hand wheel which, through oil- bathed skew gearing, operates the countershaft carrying the pulleys, chains and counterweights. Since the pouring lip is in line with the tilting axis there is no variation of height, or movement lore and aft of the lip during pouring, which facilitates precision of operation. A unique feature of the furnace is the preheating of the cold air supply from the fan before it reaches the burners. This is achieved by passing the air through an annular dome over the furnace lining, the connecting pipes of which are self-sealing when the furnace is in the normal upright position. It is claimed the use of preheated air ensures a dry atmosphere inside ;the furnace, provides greater pressure at the nozzle and, at the same time,: produces an in- candescent flame with .more rapid melt- ing temperatures. A final advantage is the . improved combustion of the atomised oil enabling a heavier grade to be used. A charge of 5001b. of aluminium re- quires a melting time of ninety minutes The Monometer pre-heated furnace. to two hours with an oil consumption of approximately i£ gall, per ioolb. of metal, and 1,5001b. of high-temperature bronze takes two to two and a half hours, the consumption of oil being in the neighbourhood of 1 gall, for each ioolb. of bronze. The wartime address of the Monometer Manufacturing Co., Ltd., is Barton Towers, Clifton Drive, Westclirl-on-Sea, Essex: ;::;./.- «: • • ••-;• ••..-• < JANUARY 4, 1940. Electric Light in Glasgow WHO had the first electric light inGlasgow ? Very few woukl be able to answer that question. It was Lord Kelvin, and the man who helped to instal it at Lord Kelvin's house in the University recently celebrated 63 years' continuous service with the firm now called Kelvin, Bottomley and Baird. He is Mr. Robert Todd, and was presented by Mr. Fred C. Stewart, chairman of the company, with a wallet containing treasury notes. Mr. Todd, who is in his 82nd year, is still hale and hearty. He recalled the days when history was being made in the old factory in Renfrew Street, where were made early electrical, instruments for submarine telegraphy and for measuring electrical current. The Barn and Stroud range finder was also made in the old works, until a special factory was built at Anniesland. The old family traditions are still maintained at Kelvin's works, and there are many cases of sons and daughters, and even grandchildren, following the trades of their ancestors in the firm.

Boulton Paul Meeting AT the fifth ordinary general meetingof Boulton Paul Aircraft, Ltd., held at Birmingham on November 30 a divi- dend of 7| per cent, was announced. After making a provision of ^42,000 for taxation a disposable balance of ^66,552 remained. Of this sum the divi- dend absorbs ^24.375. a further £IT,H& is transferred lo general reserve and the residue, /20,83c), is carried forward to the next account.
