Abstract: A method is disclosed for operating a steam turbine using turbine reserve capacity for attaining operation at elevated loads. In a preferred form of the invention, a bypass overload valve is provided in parallel with the steam admission control valves but is connected to discharge steam to a lower pressure stage of the turbine. During operation of the turbine at less than full load, the bypass overload valve is maintained closed and the control valves are positioned to sustain a preselected load. As load on the turbine increases, the control valves are increasingly opened until they have all reached their fully opened position corresponding to a nominal rated capacity of the turbine. Then, at the discretion of operating personnel, the bypass overload valve is fully opened while simultaneously one or more of the control valves is throttled to offset any steam passing through the bypass overload valve in excess of the amount required to sustain the preselected turbine load.

Abstract: Portable target apparatus includes a variable size aperture for a baseball pitcher and includes a net which comprises a catcher or a stop for the balls which are pitched through the selectively variable target area. The size of the target aperture area can be varied by horizontally and vertically movable straps which are mounted on the target frame structure.
