Abstract: Abstract of the Disclosure A combination of a programmable logic controller with analog circuitry.  The analog circuitry includes a summation point to which several items are coupled. Analog inputs are selectively coupled to the summation point through analog switches.  Also, the output of a digital to analog converter couples to the summation point.  Still further, the analog output for the controller is obtained from a sample and hold circuit which has its input connected to the summation point and which includes means for outputting the analog value at its output back to the summing point.  Even still further, a comparator input couples to the summation point.  The arrangement provides for direct processing of analog information either by direct output of analog processed analog data or by obtaining one bit data from the comparator which represents whether a threshold has been reached by the analog data.  Digital processing of the analog data may be accomplished, if necessary by using the circuit to convert from analog to digital and back again. The equipment is designed so that digital or analog, input or output cards may be inserted into any of the I/O positions without rewiring.

Abstract: METHOD AND APPARATUS FOR               INITIATING THE EXECUTION OF INSTRUCTIONS         ABSTRACT       A method and a central execution pipeline unit for initiating the execution of instructions of a synchronous central processor unit (CPU) of a general-purpose digital data processing system. Instructions containing address information and an instruction field are obtained in program order from an instruction fetch unit of the CPU.  In a first stage, requiring one clock period, the address information of an instruction is utilized to form the carrys and sums of an effective address and to initiate the formation of a virtual address.  Concurrently, the instruction field is decoded to produce memory command signals and data alignment signals.  In a second stage, the formation of the effective and virtual addresses initiated in the first stage is completed, and the word address portion of the virtual address is transmitted to the cache unit of the CPU.  Also during the second stage, memory command signals are sent to the cache unit and the instruction field is converted to an execution code for one of a plurality of execution units, and the execution unit to execute the code is designated.  In a third stage, the virtual address is converted to a physical address, or real page number which is transmitted to the cache unit.  The execution code is sent to the designated execution unite; however, if the execution unit is the central unit, the execution code for that unit is converted into execution unit control signals.  In the fourth stage, data alignment control signals are sent to a distributor of the central execution pipeline unit.  The distributor will align the data in accordance with the alignment control signals.  In the fifth stage, the addressed execution unit is enabled to receive the addressed operand or target word from the distributor, and the instruction field of the instruction is transmitted to the collector unit of the CPU.  During the next stage, results of the execution of an instruction by the central execution unit are loaded into a results stack and indicator registers of the central execution pipeline unit are updated.

A thermographic material comprises the same combination of components without the need for photographic silver halide.  A silver image and dye image are produced in such an exposed photothermographic material by heating the material until the silver image and dye image are produced.  An image in a thermographic material is produced by imagewise heating the material.  Ureidoaniline silver halide developing agents are also useful in processing compositions for photographic silver halide materials.

Abstract: Abstract of the Disclosure A process control system including a method and apparatus for preventing a controller from overdriving a stuck valve.  Control is based on the output of the con-troller if the valve is not stuck.  However, if the valve becomes stuck, the variable high or low limit takes effect until such time as the valve becomes unstuck.  This prevents a situation from being created in which sufficient force is placed on the control valve to cause the control valve to go to a completely open or completely shut position when the control valve does become unstuck thus avoiding a dangerous situation.
