We are pleased More POWER NEWS w^^^^_liglni on page 154 to announce First 100 kw Wind Generator LONDON -- [McGrow - Hilt World the affiliation of News)--The first wind-driven generat* lag station is soon to be added to the British Electricity Authority's system. Preliminary trials under light inland BAKER & SPENCER, INC. breeies are to take plsee this summer ot a site near St. Albans, Hertfordshire, north of London. This is a step further with in BEA's effort to overcome the acute shortage of electricity and at the aame time to save precious coal. FREDERIC R. HARRIS, INC. The new generator works on tho do*, pression principle, an arrangement whereby the generator is directly cou pled to an air-turbine, both being at or near ground level and neither being Consulting Engineers mechanically connected to the propel ler. The propeller, by extracting air from the system, sets up a pressure dif ference across the turbine sufficient to cause rotation. The pilch is adjusted automstleally 27 William Street by a hydraulic system so that the ro- Nbw York.

Hie f propeller operates down wind of the tower. sssss#' Hie electrical equipment comprises one 100 kw, 415 volt, 8-phase, synchron ous induction generator with exciter, which is started from rest as an induc tion motor. When synchronous speed Is approached, direct current is fed into the field Cousing the generator to oper ate as a synchronous motor running under no load conditions. Air is then admitted to the turbine which in turn drives the motor in synchronism with the connected system. Fully automatic control gear is connected to the genera tor by flexible armoured cables. floe* V*u* valvM eotllf wkw* itirji b*lpwg, I*f mod Actonl ftnd Monopileal *i*ni 4)*Mbutl*n.

Mining progress is pictured in new Ganfner-Denvor movie entitled Paj Din. It drsmsthes the improved techniques which mining men and mining equipment manufacturer* have developed for produc ing greater and greoter tonnage* of iron, copper, uranium, sine, nickel, lead, and all the other minerals whleh are used so abundantly today. It showa, for example, the strenuoua hand drilling methoda prac ticed yean ago, followed by acenea of miners using early compressed sir powered rock drill models, and then the neweat high peed aulomatle drilling equipment.

All other eleJCrments of the station are of the outdoor type ^resulting in maximum economy of construe* rj.Uon for the Arizona climate.

Tho turbine is served by an k'FIngersoil-Rand Rectangular Condenser con* Detaining 27,500 sq. ft. of cooling surface. Con* M*nser cooling water is handled by two I-R vertical pumps handling 25,800 gpm. Con* densate is handled by I*R vertical pumps. Unit No. 2, now under construction, will hove a rating of 60/66,000 kw. It will be served by a 47,500 sq.ft.I-R Rectangular Condenser, also of two-pass and vertically divided design. The condensate and circulating pumps will again be supplied by Ingersoll-Rand. These Ingersoll-Rand Condensers save valu able space because their rectangular design makes the most efficient use of the rectangu lar space available below the turbine. And installation cost is minimized because they are completely assembled' in tho shop, then shipped in large sections, completely flanged for easy erection without any held fitting or strength welding.
