Abstract: An integral, preferably cast steel center plate includes a generally rectangular flat base portion defining spaced mounting flanges on opposite edges. A central circular boss extends from one face of the base, for engagement with a mating center plate bowl, and a pair of beams extending from the one face between the mounting flanges on opposite sides of the boss. In assembly to a car underframe, the mounting plate flanges are bolted to the longitudinal supporting flanges of the center sill with the beams stiffening the center plate for better resistance of eccentric forces.

Abstract: A method of determining the existence and quantity of an element in a formation. A portion of the formation is irradiated with neutrons and the gamma rays emanating from the formation due to induced radio-activity, or ''''activation'''' from thermal neutron capture by the element of interest are detected and recorded. The thermal neutron capture cross section of the formation is determined. The product of the gamma ray emission and the thermal neutron capture cross section is obtained as a quantitative indication of the element''s abundance in the formation.
