Dow Chemical Drafts K.U... Brush Named to Direct Magnesium Experiments
BY JOY MILLER
The lightest structural metal in the world is being mined from the sea—and the University has a hand in it.
Magnesium, millions of pounds of it, is needed for use in implements of warfare. To supply this need, the Dow Chemical company of Midland, Mich., is extracting the metal from sea water, and has commissioned Edward E. Brush, associate professor of aeronautics here, to conduct research on magnesium alloys.
Before coming to the University last September, Brush was an engineer with the Lockheed Aircraft corporation in California, where he specialized in studies for the use of magnesium alloys in aircraft construction. His familiarity with the metal will help in his research to determine the tension impact and fatigue strength of the metal. As far as he knows, Brush is doing the only work ever done on tension impact. Two Departments Cooperate
The department of applied mechanics under Professors F. L Brown and A. M. Ockerblad is cooperating with the aeronautical engineers in this research. Brush is being assisted in the project by Jules Saut and Walter Voigtlander, senior engineers.
Professor Brush attributes the importance of magnesium to its lightness. It weighs two-thirds as much as aluminum, the lightest structural metal used at the present time. For that reason magnesium has a widespread use in aircraft production.
The 180 pounds of magnesium alloy that go into a large airplane engine do the work of 270 lbs. of aluminum—the difference in a four-ton bomber means that two extra men or 360 pounds of bomb load or gasoline can be carried.
In plane manufacturing magnesium alloy is at present used for engine parts and for small castings and
Alterations Made In Sewing Schedule
Mrs. Paul B. Lawson and Mrs. A. T. Walker, co-chairman of the University's Red Cross sewing project, recently announced a change in the sewing room's schedule because of small Tuesday morning attendance.
The sewing room, which is located in room 116, Fraser hall, has been open Tuesday, Wednesday, and Saturday mornings from 9:30 to 12 and on Tuesday, Thursday and Friday afternoons from 2 o'clock until 5. The only change is elimination of the Tuesday morning session from 9:30 to 12.
Mrs. Lawson said that despite the small attendance on Tuesday morning, the other periods have been well attended, especially during the last week.
The University's Sewing Room is open to all students and members of the community who wish to sew or knit for the boys in the service and for civilians in war zones. It is a branch of the down town Red Cross Sewing Room and is working directly through it. Since the project began at the beginning of the second semester, the following garments have been made by the volunteer workers: 10 women's skirts, 5 woolen dresses, 5 bed jackets, 3 boys' shirts and 4 mens' bath robes. Several lap covers for hospital use are just being completed.
forgings. When it comes into more common use, magnesium will be used in making landing gear fitteds, control pedals, fuselages, wing skin, and control surfaces—replacing the heavier aluminum alloys.
The scarcity and lack of understanding of this important metal has led to a limited use of magnesium alloys, upon which Professor Brush will conduct his experiments.
The research will include testing and comparing properties of magnesium alloys with those of aluminium and plywood for making aircraft control surfaces. Determining the fatigue and impact strength of magnesium alloy, and casting and forging also will be undertaken, Brush explained.
In mining the magnesium, Dow company founded a site at Freeport, Texas, and pumps in 300,000,000 gallons of sea water a day. The process is simply burning oyster shells for slaked lime, mixing it with sea water, treating this with hydrochloric acid, separating the chlorine from the magnesium, and drawing off the resultant metal and casting it into ingots.
Magnesium is a metal which sprinkl into use almost overnight. During the last war 284,000 pounds were produced annually. This year we will make 125,000,000 pounds, with plants being constructed to turn out 400,-000,000 pounds a year.
Aside from its use in plane manfacturing, and for use in making incendiary bombs and signal flares, magnesium will be used after the war for household metal implements. Vacuum cleaners, baby carriages, and pianos all probably will be changed because of this lightweight champion. From warfare to domesticity is a long stride, but magnesium can take it.
Brunswick, Me. — (UF) — Wilfred A. Duquette, court recorder here, boasts that every article of furniture in the dining room of his home was hand-carved by himself. Duquette, who long has made woodworking his hobby, hopes eventually to be able to say that every piece of furniture in his home was made by his own hand.

Topeka, Kan.—(UP)—Gov. Payne Ratner has asked the Kansas State highway commission to conduct a survey to determine the amount of scrap metal available in the state in the form of abandoned bridges, structures and equipment owned by the state or by various counties.
Officials of the federal bureau of industrial conservation have notified Ratner that the war production board is interested in uncovering every possible source of scrap metal and is "stimulating the scrapping of abandoned structures containing iron and steel."
The bureau made it plain in a letter to the governor, that "it is essential that we tap every large source of dormant scrap metal."

PI K. A.'S—
(continued from page five) Chi. Ivan Josserand took scoring honors for the Acacia's with seven points. At half-time the Sigma Chi five held a narrow 15 to 13 lead, but the Acacia defense fell apart in the last half and the winners pulled away.
John Moore Coop could not hold an early lead, and fell before a late Rock Chalk rally 26 to 22 Friday night. The losers had led 16 to 12 at the half. Lorraine Chestnut, John Moore guard, was high point man for the game with 11 points. Orville Krzetmeier racked up four field goals for the victors.
Phi Delt's Upset Phi Gam's
The Phi Gamma Delta "C" squed became the first Phi Gam intramural basketball organization to taste defeat as they fell yesterday morning before the Phi Delta Theta "C" men 24 to 12. Ralph "Bud" Weir took the leading role in the Phi Gam upset as he contributed six field goals to the Phi Delt total.
The Sigma Alpha Epsilon "B" team continued its fast pace in Division IV competition Saturday as it defeated the strong Phi Kappa Psi "B" team 28 to 26. The Sig Alph's held a narrow 12 to 11 lead at half-time.
John Horner, fine Phi Psi center, took scoring honors for the game with 11 points. Earl Musser and Jim Sandifer contributed nine and eight points respectively to the Sig Alph attack.
The Pflugerville Pflashes forfeited two games in weekend play to the Tau Kappa Epsilon and Theta Tau quintet. Other forfeited games were Sgma Chi "D" to Beta Theta Pi "C", Newman III to Newman II, and Alpha Tau Omega "B" to Pi Kappa Alpha "B".
The Fhi Delta Theta "C" vs. Sigma Chi "C" game, previously recorded as a forfeiture by the Phi Delt's, has been reclassified as a postponed game, and will be played off this week.
Jimmie Lunceford and his Harlem Express will appear at the Granada in "Blues in the Night" beginning today for 3 days. He will play for the Junior Prom Friday.
