Accord on stage PATRONIZE KANSAN ADVERTISERS Africans cast in roles A curious harmony pervaded "The Literary Society" production last night in Experimental Theatre. The actors were a unique element. But the irony of the situation satire was a greater element. The cultural snobs of Henry Ofori's Ghana hamlet were universal in character, sniping at each other and picking the details of the meeting apart. They basked in the self-taught knowledge that they were cultured. Moscow confident SOFIA, Eulgaria—(UPI)—Russia appeared determined today to overrule Romania's veto and call a world Communist conference to isolate China. The public clash Tuesday between Russia and its maverick ally also indicated Moscow is now confident it has enough strength among the world's 90 Communist parties to weed China out of the international movement. Soviet Communist party chief Leonid Brezhny publicly endorsed a call for a Communist summit conference on China in a wildly applauded speech Tuesday before the Bulgarian party congress and 80 foreign delegations. BERLIN—(UPI)—Two Western investigating teams assigned to study the wreckage of a Pan American World Airways-Boeing 727 jet cargo liner, were blocked today by a Soviet attempt to run the plane crash into a new cold war incident. Communists block crash investigation The Communist East Germans, meanwhile, began an investigation of their own. All three crewmen died when the plane crashed Tuesday in a snowstorm while on a routine mail flight from Frankfurt to Berlin. The crash site was a Soviet army training ground near Dallgow in East Germany, about three miles outside East Berlin. The Communists today steadfastly refused to permit the investigating teams—one from the airline and a second made up of Western allied air experts—to travel to the site of the crash. The Soviets, who belatedly confirmed the crash and the death of the crewmen Tuesday, said all further information would have to come from the East Germans since the crash occurred on East German territory. Diplomatic sources said the Soviet action was an attempt to force Western recognition of the East German government. DISPLAY PRISONER KINSHASA. The Congo — (UPI)—Lt. Col. Tshimpola, the captured leader of the Katangese rebellion at Kisangani (formerly Stanleyville), was paraded in front of 10,000 howling Congolese soccer fans Sunday. THE PETTINESS is universal, all right. But in an African nation where imitation of western tradition is saluted, the ludicrousness perhaps more pronounced. With his hands tightly bound behind his back, Tshimpola was marched around the stadium by a squad of Congolese military police just before the kick-off of a football match. The acting was predominantly African. And it's believably African with the uninhibited, fluid movement, sing-song lilt that makes English sound African, and brilliant flowing costumes. Yet above and beyond the "Africaness" is a universal satire of snobs who attempt culture, yet cannot abandon their own humanness. tors—and still better, with enjoyment. They acted a satire on the feeble attempts of Africans, yet the general application allowed them to laugh, along with full-house audience. THUS, IN A duality of self-criticism and universal satire, the students let go and hammed it up. They performed with all the force and vitality of seasoned ac- Under the guidance of Kay McNeive, Topeka graduate student and director, the one-act sketch moved with assurance. Actors were Yves Puzo, Haiti graduate student; Thomas Wilson, Ghana sophomore; Girma Negash, Ethiopia senior; Ebenezer Ewanga, Cameroon senior; John Peck, Brooklyn, N.Y., graduate student; Swaebou Conateh, Gambia senior; George Kuria, Kenya junior, and Kayode Edun, Nigeria freshman. Daily Kansas 11 Wednesday, November 16, 1966 We set out to ruin some ball bearings and failed successfully The Bell System has many small, automatic telephone offices around the country.The equipment in them could operate unattended for ten years or so,but for a problem. The many electric motors in those offices needed lubrication at least once a year. Heat from the motors dried up the bearing oils, thus entailing costly annual maintenance. To stamp out this problem, many tests were conducted at Bell Telephone Laboratories. Lubricant engineer George H. Kitchen decided to do a basic experiment that would provide a motor with the out to ruin some ball bearings by smearing them with an icky guck called molybdenum disulfide $ (\mathrm{Mo S}_{2})。 $ worst possible conditions. He deliberately set Swock! This solid lubricant, used a certain way, actually increased the life expectancy of the ball bearings by a factor of ten! Now the motors can run for at least a decade without lubrication. We've learned from our "failures." Our aim: investigate everything. The only experiment that can really be said to "fail" is the never tried. AT&T Bell System American Telephone & Telegraph and Associated Companies
