Christy, until recentlv Di rector of New York's Bureau of Smoke Control, has ;us; announced that he has severed his connection with the citv and opened an office as consulting engineer at 3A Park Row, New York. Christy has had many years' experience in air pollution and smoke control work, as well as in power and heating plants. Also he has been active in the ASME for many years and is a past chairman of the fuels division. a;;u water handling equipment in steumcieerne power plants was inciuJed in the lour papers given at the Eiectricui and Communica tionsSvnipos!uni held Wednes day.

It will be of tremendous technical value because it will enable engineers to make almost instantly, calculations that might other wise have taken weeks. Weighing only abouc 75 lb, it is conveniently portable. The synchronograph consists of a repet itive surge generator that simulates a boit of lightning or surge; a remote re ceiver that picks up the original surge; and two oscillographs that record the surge at the poinc of reception. The repetitive surge generator supplies the simulated lightning wave 60 times a second to the power line or electric Because o: the increasing importance of mathematical methods ir. the sieid of power engineering, a group devoted ex clusively to applied mathematics has been organized under the name o: Mathemati cal Computing Service. It specializes ;;i psnorming services for industries and universities desiring engineering calcula tions, charts and nomographs of a high decree of complexirv and the treatment of related mathematical problems in the neld of power engineering. An imoortar.c function of this group is die matnemarical formulation and complete solution of a problem from given physical data. The staff consists of consultants holding doc torate degrees who are quaiiiied co treat problems in applied mathematics related to the physical sciences, if v-;ur power plant organization is interested in using such a service, the Editors will put vou in touch with it if vou will drop us a iine, referring co the Engineers' Preview. * * * Allis-Chalmers now has under con struction its first completely supercharged steam turbine generator. It is shown m the illustration alongside a standard hvdrogen cooled machine having the same racing. See next page. This latest and most important step in che history of size reduction of steam cur- *** equipment under test. The surge chus in bine generators is a further development The twelfth generating plant of the Commonwealth Edison-Public Service of Northern Illinois system, to be known as the Will County generating station, will troduced into the system may amount to only 250 or 300 volts -- a relatively small voitage compared to an actual lightning stroke. However, the smaller voltage following the first use of supercharged cooling in $he rotor of a 60,000*kw AllisChaimers generator installed in mid-1951 (Power Engineering, January 1952). be built on a 216-acre site bordering the Chicago Sanitary and Ship Canal between Lock-port and Lemont. ` Preliminary excavations and sub-struc- .1 y ture work is already well under way for the station building, crib house, water - tunnels, barge docks, coal storage yards, .1 : electric switchyard and ocher facilities. It is expected the station will be completed and two new units in service by late 1954. The new Will County stacion site is adequate for the development of a one million kilowatt power plant -- more . than three times the initial capacitv to . be installed -- and the new station and - its related facilities are designed to pro vide for additional generating units. ' The property is served by the E. J. & E. Cr Railroad which has connections with all tf rcajor Chicago area trunk lines and by -v the Illinois Waterway, over which coal j_r can be barged direct to the site.
