Abstract: 1,005,940. Controlling reactors. SULZER BROS., Ltd. Sept. 3, 1964 [Sept. 19, 1963], No. 36138/64. Heading G6C. In a nuclear reactor the power generated is controlled in correspondence with the product of core neutron flux and the heat output. The former provides a rapid indication of the output while the latter gives an accurate, but slower, response to the output. As shown, the reactor 1 is adjusted by control rods 20 and supplies superheated steam to the turbine 7 through heat-exchanger 4. The rod 20 is positioned by the output from multiplying unit 30 which receives the output signals of the flux measuring device 27 and the reactor coolant-gas flow measuring device 28. It is stated that as the coolant temperature and pressure are constant, the coolant rate of flow is a measure of the reactor heat output. Further subsidiary control loops are provided; the coolant-gas pump 14 is adjusted in accordance with the coolant outlet temperature at 13, the controlrod signal is modified by signals from the turbine inlet pressure sensing device 25, the output from 30 is fed back by line 26 to the pump 14. The delay device 35 reduces the effect of transient charges in the reactor flux. In a modification, the output of 28 may be divided by that from 27 and the resultant fed as a further signal to the multiplier 30.

In a liquid cooling system for a piston a throttling device provided on the outlet side of the system is effective only during a limited part of the piston movement extending between two points, one before and one after bottom dead centre. The two points are preferably those at which reversal of piston acceleration occurs. A further throttling device similarly effective may also be provided on the inlet side of the cooling system. The throttling device may be in the form of an oscillating valve incorporated in a stationary joint 13, Fig. 3, of an articulated pipe 12 on the outlet side of the cooling system. Coolant returning through the bore 16 of pipe 12 passes into the bore 17 of a part 20 having a cut-away sector which cooperates with an outlet passage 21 when the pipe 12 is in the upper position 12<SP>1</SP> shown but is out of alignment therewith when the pipe is in the lower position shown in dotted lines. In the latter position, however, a small flow of coolant still occurs through the clearance 18 around the part 20. In a modification, for a telescopic pipe cooling system, the outlet telescoping tube during its downward movement in the stationary tube closes an outlet aperture therein. In another modification, Fig. 5, the coolant outlet pipe 11 fixed to the piston is surrounded by a spring-supported weight 25 which, when the engine is running and the piston is in the region of the bottom dead centre, is forced downwards by its inertia and closes an outlet aperture 27 in the pipe 11.

With a positive input at RON, T1 becomes conductive to hold Z n1  below its breakdown voltage so that T 3 , T 4  are cut off. C 3  then charges until Z n4  breaks down turning on T 5 , T 6  and turning T 7  off, to produce a positive output at D. Short spurious positive pulses produce no output at D since C3 does not charge sufficiently to break down Z n4 . With a negative input at RON T 1  is cut off, Z n1  breaks down and T 3  turns on to charge C 2  until Z n2  breaks down switching on T 4 , T 7  and switching off T 6  to produce a positive output at C 1 . Short spurious negative pulses produce no output at C 1  since C 2  does not charge sufficiently to break down Z n3 . Operation of the circuit may be inhibited by removing the earth potential from point A. Z n2  then breaks down turning on T 2  to hold T 3  cut off irrespective of the input at RON.
