A process for preparing a silver-containing catalyst for the selective oxidation of ethylene to ethylene oxide including the steps of: (a) providing a multimodal support, (b) preparing an impregnation solution comprising a silver component, (c) impregnating, at least once, the multimodal support of step (a) with the silver-containing impregnation solution of step (b) to form an impregnated support; (d) subjecting the impregnated multimodal support from step (c) to a removal means, such as a centrifuge, at least once, for a time sufficient to remove impregnated silver impregnation solution from the multimodal support and to control the amount of silver in the pores of the multimodal support by selectively removing impregnated silver impregnation solution from a set of larger pores in the multimodal support; (e) roasting, at least once, the multimodal support after the step (d); (f) optionally, repeating the impregnation step (c), (g) optionally, repeating the centrifugation step (d), and (h) optionally, repeating the calcination step (e).

A connector system is configured for macro motion. Two mating terminals are configured so that during macro motion cycles, the resistance between two terminals does not substantially increase. One terminal can have multiple, somewhat spherical-shaped mating surfaces while a mating surface on the other terminal can be flat. The mating terminals can be configured to provide desirable resistance performance after more than 5000 cycles of macro motion.
