&t the Motioned GAemlool &t 10, and possibly 40, of the y o u n g scientists of the future. During the institute the contestants will compete in final examinations f o r the scholarships, which will result i n the awarding of eight four-year Westinghouse Science Scholarships of $40O eacli and two four-year Westinghouse Science Grand Scholarships of $2,400 each, worth $60O per year. One boy and one girl will b e selected as winners of the Grand Scholarships. Alternates will b e named. Additional $100 scholarships will be awarded at the discretion of the judges. The Science Talent Search is administered by a committee of four: Harlow Shîipley, director, Harvard Observatory»
Eliminate MANIFOLDING Multiclone's exclusive vane design permits any number of tubes to be installed with one inlet header and one outlet header sim plifying construction and eliminating the complications of manifolding. Less mate rial is needed. Less floor area and less head room are required. Because the gas travels over a smaller surface there is less surface subject to wear and because of the vane type of construction, should wear occur, it can affect only parts that are easily and readily replaceable without dismantling the entire unit. In the Multiclone, the sim plified header construction together with the enclosure of the tubes by the hopper greatly reduces heat radiation. This facili tates temperature control and where con densation might occur reduces insulation requirements to a minimum. The Multiclone design makes possible its installation in existing structures in what would other wise be wasM- spare J»:.«J m t>laces where manifold· . . v o Id be impossiL,/·· The smgle manhole ι trough which all tube* can be reached sim^ ! ; f es inspection. Thus the elimination of mai». '-"·»»» simplifies installation, saves space, decreases v u u n g surface, reduces heat radiation and gives better temperature control.

Corrosion Division o f Electro chemical Society Formed # ^ ) Ν OCTOBER 9 a t the fall convention in ^^^ Detroit, the Corrosion Division of T h e Klectrochemical Society was organ ized. At this meeting bylaws were adopted a n d t h e following officers elected : chair man, L. G. Vande Bogart, Research and Development Laboratories, Crane Co., Chicago, 111.; vice chairman, H. H . Uhlig, General Electric Co., Research Labora tory, Schenectady, Ν . Υ . ; secretarytreasurer, R. H. Brown, Metallurgical Division Aluminum Research Labora tories, Aluminum Co. of America, New Kensington, Penna. The Corrosion Division was organized because of the interest displayed b y a large number of the members of The Electro chemical Society in this phase of the work. I t s object is to coordinate the interests of t h e society relating to corrosion with indi viduals and organizations which are par ticularly interested and active in this field, t o solicit papers, and plan symposia.
Conservation of Critical Materials APPLICATION to the war production ef-
" ^ fort of all the skill and management "'know how" acquired b y General Motors through many years of manufacturing ex perience is resulting in the conservation of thousands of tons of critical materials, in important savings in man hours (thus releasing men and machines for further -vital work), in sharply reduced costs, in t h e organization of new methods in main tenance and service, and u substantial contributions to an advancing military technology, Alfred P. Sloan, Jr., chairman o f the corporation, states. M?\ tl-oan says that production rates have beci. accelerated, engines have been increased in aorsepower, guns have been simplified and given longer life, and im provements have been made in tank con struction, in airplane propeller design, and in the manufacture of shells. New devices have been developed, new characteristics built into old devices. Meanwhile, a sound basis has been established for continued advance in war production techniques. No manifolding.
