Abstract: MICROCONTROLLER FOR DISK FILES            Abstract A microcontroller for controlling the bidirectional transfer of data between a control unit and a plurality of disk drives is disclosed.  The microcontroller has a fixed machine cycle time for executing each instruction and is arranged to fetch the next instruction during the execution of the current instruction.       The microinstructions are stored in an addressable memory and each addressed instruction is transferred to a control subsystem in response to the operation of a second subsystem whose function is to generate the address of the next instruction to be executed. A third subsystem is provided for executing the instructions which is also employed during branch type of instructions for assisting the second subsystem in generating the next address.       The second subsystem also functions to supply the third subsystem during execution of certain instructions, data to be stored for use during subsequent instructions.       The subsystem for executing instructions is characterized by a plurality of data sources which are selectively interconnected through the ALU to the ALU register during the input phase of a machine cycle and a plurality of data destinations which are selectively connected to the output of the ALU register during the output phase of a machine cycle.  One of these destinations is the subsystem for fetching the next instruction.       The subsystem for fetching the next instruction is characterized by a plurality of partial address generators which operate selectively with the other subsystem to generate the complete address of the next instruction.       The controller also employs d multilevel priority trap system for interrupting the normal sequencing of instructions in response to events occurring in the devices being controlled or events within the microprocessor.

Abstract: 21                  49,769 ABSTRACT OF THE DISCLOSURE     A combined cycle system includes a boiler having a fluidized bed which provides heat from burning coal for generating steam used to drive a steam turbine generator. After compressed air has been heated to 1400°F in a fluid bed air heater,  it is further heated in combustors of a combustion turbine by combustion of a gas obtained from low temperature pyrolysis of the coal in another fluidized coal bed which is pressurized.  The hot gaseous products drive the combustion turbine and a connected generator.          Char from the pyrolysis and supplementary coal are burned in the boiler fluid bed with the exhaust of the gas turbine.  Sulfur in both the coal or char and the gas turbine exhaust is captured by limestone in the bed.  The high heating value of the pyrolysis gas and the high air preheat require a relatively small volume of gas.          Corrosive and sticky constituents of coal are not vaporized at the low pyrolysis temperature of 1000°F. The small quantity of gas and the absence of corrosive constituents  permit  satisfactory  operation  of  the  gas turbine  with  only  dust  removal  from  the  gas  without requiring gas cooling.

Abstract: ABSTRACT OF THE DISCLOSURE           An active data bus is disclosed comprising a plurality of multiplex terminals serially interconnected to form a closed loop.  Each terminal is capable of assuming a relay configura-tion wherein data signals received from a preceding terminal are retransmitted to a succeeding terminal, and of assuming a trans-mit access configuration wherein the loop is opened at the terminal and locally-generated data signals are introduced therein.  Each terminal is further capable of functioning in a diagnostic mode whereby system access is obtained by programmed action of the terminal's control microprocessor, and of func-tioning in a highly efficient user access mode whereby access is obtained without microprocessor action by virtue of hardware "capturing" a special access window bit introduced by the last-accessing terminal.  Unique circuitry permits this last-accessing terminal to close the loop after introducing its data but before the access window has completely traversed the system.  The access window is thereupon "trapped" on the closed loop and continuously circulates thereafter until it is "captured" by the next terminal desiring access.  In accordance with a preferred embodiment of the invention, the data bus includes redundant data paths between terminals and the terminal control microprocessors are each capable of selecting either of two receiving paths and either of two transmitting paths in order to form the closed loop.  The programs of the terminal control microprocessors include cooperative diagnostic control-ler and diagnostic follower algorithms wherein the plurality of microprocessors intercommunicate synchronously via the diagnos-tic mode to construct an optimum data loop from available system resources.  After constructing said loop, the member terminals collectively switch to the user access mode to asynchronously transfer data generated by user data sources directed to user data sinks.  The cooperative diagnostic algorithms are initially entered upon applying power to the system and may be re-entered at a later time if certain status signals monitored by a termi-nal control microprocessor indicate that such action is neces-sary to efficiently maintain communication.
