Abstract: A locomotive diesel engine waste heat recovery system for converting waste heat of engine combustion into useful work. A thermoelectric module is connected to the hot engine exhaust to provide a high temperature heat source, and the engine coolant system is also connected to the thermoelectric module to provide a low temperature heat source. The difference in temperature of the heat sources powers the thermoelectric module to convert waste heat of the engine into electricity to power selected devices of the locomotive.

Abstract: An improved semi-articulated railway power bogie has a pair of multiple axle sub-bogies semi-articulated for creep force turning control while retaining freedom of rocking and relative longitudinal motion. An equalized centered bolster suspension and low load transfer rod linkage maintain high equalization of loads and tractive forces at the wheels to provide overall high adhesion and curving efficiency. Various improvements may include a preloaded resilient compression element in an articulating mechanism for improved sub-bogie turning control, two piece bearing adapters carrying primary spring suspensions and with rubber bushed traction rods and lateral thrust control for transmitting longitudinal and lateral forces to sub-bogie frames, and rubber bushed nose links connecting traction motor nose connections to transoms of the frames.

Abstract: A phase separator apparatus is disclosed which utilizes phase separator modules for insertion in a separation tank. The modules include a frame for retaining a plurality of impingement plates within the frame utilizing removable retention means, such as slots, allowing easy removal and replacement of the impingement plates. The phase separator module also includes vertical baffles for blocking the flow of fluid to be separated and forming a quiescent region on either side of the impingement plates normal to the direction of flow to the fluid to be separated. The removable retention means, such as slots in the frame, not only allow removal for cleaning and maintenance of the plates, but also provide a means for adjusting the spacing of the gap between the plates, the plate length or a combination of both, in order to modify the efficiency of the separator.
