Filed: 1971-11-16
Abstract: 1371369 Process control; controlling nuclear reactors BABCOCK & WILCOX CO 16 Nov 1971 [16 Nov 1970] 53247/71 Headings G4A and G6C A process control system includes a plurality of digital computers each arranged to calculate a selected mathematical expression which is a function of sensed operating variables of the process and which has a value lying within a given range if the process is operating safely and to generate a shut-down signal whenever the calculated expression does not lie with the given range, and a coincidence logic circuit arranged to generate a process shut-down signal on the simultaneous receipt of shut-down signals from a minimum number of the computers. As described, the process involved is a nuclear reactor and the computers calculate, using identical or different-mathematical expressions, the departure from nucleate boiling ratio from input data representing reactor flux, coolant flow rate, coolant pressure, and coolant inlet and outlet temperatures. The data are sensed by transducers and are fed via analogue/digital converters to the computers. In the embodiment each computer calculates the same mathematical expression but is serviced by independent transducers and A/D converters for additional safety. In such circumstances common transducers and converters may be used. Where each computer calculates a different function different input parameters may be used. The coincidence logic circuit generates a signal initiating reactor shut down when the calculated expression from a minimum number of computers, e.g. 2 out of 4, is not within the allowed range.  The computers may be used to self-check the transducers by feeding them a known signal and comparing the resultant output. The computer may also check for system consistency, e.g. by comparing the measured coolant flow rate with pump speed. The computers may also be used to calibrate the sensors individually by computing a function of the remaining sensors which is related to the parameter measured by the sensor being calibrated.

The other end of the arm 26 is rigidly connected midway between the front and rear wheels of the tractor to a torsion bar 22 which extends rearwardly therefrom in  a tube 10 swingably mounted on the tractor by lugs and a pin 18. Carried at the rear of the tractor is a tank 40 which acts as a reservoir of hydraulic fluid. The tube 10 with a bearing for the torsion bar 22 and an oil seal 24 may be an extension of the tank 40. The torsion bar 22 is journalled in the tank 40 and is connected at its rear end to a radially extending crank arm 42 which is attached to a hydraulic cylinder 46 extending upwardly in the tank 40. The tank 40, which also contains a pump driven via a gearbox from the tractor and the devices for controlling the hydraulic operation of the rams and the mower driving motor, has a pair of bifurcated lugs 48 which engage on the short pins 52 which would otherwise carry the lower lift arms of the tractor, and is lifted into the position for use by chains 50 hung on the upper lift arms of the tractor. The arm 26 carries ramp portions 60 so that a rear wheel of the tractor can be reversed over the arm to align the tractor with the mower unit prior to connecting the two. An extra arm may be provided between the casing 28 and the tractor, requiring the provision of an extra ram and strengthening of the suspension. The latter can take the form of a torque tube concentric with the torsion bar, or of a rotational clamper and is arranged to come into play when the first arm is substantially horizontal.
