"The President stood up, made the sign of the T"

The 'T' symbol replaces the Christian sign of the cross. This is a reference to Henry Ford's Model T automobile, the vehicle that "put America on wheels".

The Model T stands for mass production and affordable prices. These are the ideas on which society in Brave New World is built. In the new world, the people are themselves mass produced and every good is affordable and readily available to everyone.
