Abstract: A turbine generator includes a plurality of spaced and parallel, transverse webs interconnected by plates to define an integral generator housing-base. Each transverse web in the generator section thereof includes a central, circular opening through which the generator rotor extends, and a plurality of apertures extending about the opening. Each transverse web further includes a walkway flange which, in association with the plates, forms a walkway, and also includes a superstructure lattice at the top thereof for supporting air cooling structure. A turbine is bolted to the integral generator housing-base, and is coupled to the generator rotor. Due to the integral generator housing-base, resonant vibrations of the base portion thereof at the generator operating frequency and at twice the generator operating frequency are eliminated, the weight and size of the turbine generator are reduced, and the turbine generator has greater structural integrity and rigidity.

Abstract: A support system is provided for a bundle of U-shaped tubes in a heat exchanger of the shell and tube type. The system includes a fixed frame including a plurality of support plates for the majority of the length of the bundle and a floating frame including a plurality of support plates for the U-bend end of the bundle. The floating frame is mounted on the tubes and is free to move relative to the fixed frame, thus allowing freedom of expansion of the tubes through the fixed frame support plates even on the occurrence of tube binding in the floating frame support plates adjacent the U-bend end.
