Budd–Michelin rubber-tired rail cars which featured innovative and distinctive pneumatic tires. The company claimed that its application of tires on its rail cars afforded both a substantially more cushioned ride and increased the cars' traction by 35%. The design of Michelin's tired wheels included an aluminum safety ring and a flange that were only used in the event of a puncture or other type of tire failure; during normal operation, only the rubber tire made contact with the rail. Inspired by Michelin's success, the Budd Company set its sights on marrying the new rubber rail tires with its shot-welded, stainless-steel carbodies; it had developed
B-factory which will begin operations in 2018. B-factory In particle physics, a B-factory, or sometimes a beauty factory, is a particle collider experiment designed to produce and detect a large number of B mesons so that their properties and behaviour can be measured with small statistical uncertainty. Tauons and D mesons are also copiously produced at B-factories, Two B-factories were designed and built in the 1990s. They are both based on electron-positron colliders with the centre of mass energy tuned to the ϒ(4S) resonance peak, which is just above the threshold for decay into two B mesons (both experiments took smaller
