Abstract: ABSTRACT OF THE DISCLOSURE-Automatic writing systems and method therefor are provided in accordance with the teachings of the present invention wherein, according to a preferred embodiment, a central processor and a plurality of peripherals including at least a keyboard, a printer unit, a buffer and a transport station for recording data on a record media are each connected to a common data bus, a common status bus, and  a common instruction word bus. Alphanumeric character data, format data, and function data may be entered from the keyboard and the presence of such data is indicated to the central processor on the common status bus.  Upon receipt of a data presence condition, program control is initiated by the central processor calculated to achieve the designated function or functions with the alphanumeric or format data presented. The program control of each peripheral by the central processor is carried out on the common instruction word bus while the degree of completion of the co?mand issued to a peripheral is indicated to the central processor on the common status bus.  Data is conveyed among the peripherals and the central processor through the common data bus for example, in a record mode, alphanumeric data entered at the keyboard is placed on the common data bus and entered on a per character basis into the central processor.  Thereafter such data is again placed on the common data bug and applied on a per character basis to the printer and buffer under program control. When a line of characters has been entered into the buffer, the contents of the buffer are recorded, again under program control, and each character to be recorded is first loaded into the central processor and there-after applied to the transport station for recording purposes.  Conversely, in a playback mode, a line of characters is read from the record media and loaded into the buffer.  Thereafter, each character loaded is applied to the printer unit, under program control, with the transfer of each character taking place through and under the control of the central processor.  This manner of asynchronous operation in data translation between a plurality of peripherals and a central processor enables a multitude of editing, revision, control and manipulation steps to be accomplished in the central processor, under program control, while allowing the overall automatic writing system to be highly flexible in operation and readily expandable.

Abstract: COMBINED CYCLE ELECTRIC POWER PLANT   WITH A STEAM TURBINE HAVING A SLIDING PRESSURE MAIN BYPASS AND       CONTROL VALVE SYSTEM     ABSTRACT OF THE DISCLOSURE         A combined cycle electric power plant includes two gas turbines, a steam turbine, and a digital control system with an operator analog or manual backup.  Each of the gas turbines has an exhaust heat recovery steam generator con-nected to a common header from which the steam is supplied by one or both of the steam generators for operating the steam turbine.  The control system is of the sliding pressure type and maintains a predetermined steam pressure as a function or steam flow according to a predetermined characterization de-pending on the number of steam generators in service to limit the maximum steam velocity through the steam generators, and reduce the probability of water carryover into the steam tur-bine.  Such control is always maintained by the bypass valve.          The turbine control valve responds to the speed/load demand only, except when the bypass valve is closed and the rate of steam generation is insufficient to maintain a predeter-mined pressure flow relationship.

Abstract: ABSTRACT OF THE DISCLOSURE           The rpm, dwell and timing of an internal combustion engine are measured by starting and stopping a digital counter on the leading edge of pulse waveforms generated either within the engine or by a timing light.  To measure rpm and dwell only the low coil signal is used.  For rpm measurement, the counter is started when the ignition points open, and stopped upon the next opening of the points.  To measure dwell the counter is started by the opening of the points and stopped when the points close, the resultant count being the inverse of dwell, and this count is subtracted from the rpm count to obtain dwell.  Timing is measured by starting the counter upon the firing of the number one cylinder, and providing an additional signal delayed in time as a function of the distributor advance to stop the counter.  The count in the counter is converted to rpm, dwell or timing by either analog or digital techniques.          A high energy ignition adapter circuit prevents triggering of the counter by a false indication of the opening of the points due to a waveform peculair to low coil signals produced in vehicles using high energy ignition systems.  A timing light delay circuit having a variable delay is incorporated with the timing light to produce the delayed signal proportional to distributor advance, the delay being adjustable within two selectable ranges.
