Electrical Power Demand Continues Growth Rate Continuation of the men, rate of growth of electrical power demand in most parts of the United States and a lorge increase in installation rate of new generating capacity were reported re* cently by Ernest R Acker, president of Edison Electric Institute, in comment* ing on results of a survey'just com* .. pleted by a group ofpower-aupply ex perts representing all sections of (he country. The survey finds that installation of new generating capacity, which in 1947 was 2,000,000 kw, will be 4,750,000 kw in 1948 and 6,700,000 kw in 1949. The 1950 installation schedule is 5,800,000 kw, ond the 1951 is 6,060,000 kw. De- liveries of generating equipment ore generally being made a little ahead of achedule, although there is some diffi culty in getting construction steel, pip ing and other construction-accessories for equipment installation. Pack Demand Esllmatt. The survey also finds that currently, with equip ment manufacturers working at full ca pacity and with their output far exceed ing all previous records, demand for electricity continue* to climb. The new estimate of peak demand for December 1948 is 1% higher than the forecast mode by the same group of experts lost May. The somewhat higher demand is Hew Arena Fleer at Madison Square Darden View of ModIion Squore Garden .oreno in New York City shows floor that wo* (old in record time of four weeks os o result of o technical development In use of threodless pipe fittings lo connect 13 miles of conceoled refrigeration piping.

COMING EVENTS Reserve generating capacity for the country as a whole during this month is expected to be 4% as compared with a 5% margin in December of last* year. President Acker said that reserves will ' be somewhat less than last winter in o few areas and somewhat greater in others, but generally sufficient to meet the needs for power. On the evidence of the present sur vey, power experts estimate that the December 1949 overage margin will climb to 8% ond that 14%, which is re garded as a normal reserve, will be reached by 195).

Trained factory representatives are located io 47 principal cities. Traps are stocked at 147 points. LaONSERVATION of your coal pile is vital these days when you have to read the newspaper each rooming to find out how much coalcosts and whether you can get any. Armstrong Steam Traps will help you save coal (or any fuel) for the following reasons: HO SHAM LOSS--no steam leaks past the Armstrong trap valve, even when there is no condensate load. When steam enters the trap, the bucket floats and closes the valve. Full steam pressure behind the valve holds it closed tightly. (The chrome steel valve and seat are hardened, ground and lapped to a precision, steam-tight fit). * NON-PRODUCTIVE RADIATION LOSS MINIMHID - with Armstrong traps,steam gives up more heat through' the steam-consuming unit, less through the supply and return lines. Removal of condeasate ana atr as fast as they accumulate assures maximum heat transfer efficiency. Stedm flow is faster. Condensate is discharged at steam temperature ~ no cooling legs, no drainage delay with radiation loss in the line to the trap. Faster heat-up, faster production. The ARMSTRONG STEAM TRAP 800X will help you select, install and maintain- traps- for maximum fuel savings. Write for a copy.
