Abstract: A power control system measures individual battery cell voltages and temperatures of a plurality of series-connected battery cells utilizing an Analog Front End, a controller that collects and analyzes the data digitally transferred to it by the Analog Front End, and a Fuel Gauge. Processes performed within the controller are configured to provide optimized representations of the data to the Fuel Gauge to improve its performance.

Abstract: This invention provides alloys having optimum high and low temperature mechanical properties for use of both the high and low pressure ends of turbine rotors in a single row power generation turbine with a service temperature profile from about 75.degree.-1200.degree. F. (24.degree.-649.degree. C.). The alloys include about 8.00-9.5 wt. % Cr and about 0.85-1.05 wt. % Mo and are heat treated at 1225.degree.-1350.degree. F. (663.degree.-732.degree. C.) for at least about one hour. The alloys and the components manufactured from these alloys preferably include a room temperature 0.2% yield strength of about 80-110 ksi (551-758 MPa).

Abstract: A turbine rotor is formed from two rotor segments that are composed of different low alloy steels, one a high temperature alloy and the other a low temperature alloy. The rotor segments have cavities in confronting faces that form an annular flange at the outer surface, with the segments welded together across the flange. A clad layer is first welded on one of the flanges and a filler material welds the clad layer to the other flange to form a composite turbine rotor.

Abstract: An abrasion resistant coating comprising a binder having dispersed therein first abrasion-resistant particles of substantially uniform size and second abrasion-resistant particles of substantially uniform size, the second particles having diameters of less than 15.4% of the first particles, the combined volume of the second particles and binder being at least about equal to the void volume of the first particles, the volume of the binder being at least equal to the combined void volumes of the first and second particles when they are interdispersed with one another.
