Title: Improvements in and relating to nuclear reactor plants
IPC: G03D15/02
Filed: 1964-10-30
Abstract: 1,012,615. Nuclear power plant. SULZER BROS. Ltd. Oct. 30, 1964 [Oct. 30, 1963], No. 44397/64. Heading G6C. A method of controlling a nuclear reactor plant in which reactor coolant is passed to a heat exchanger wherein vapour is generated from a working fluid, and in which the coolant temperature at the reactor outlet is controlled, the method comprising adjusting the flow rate of working fluid to the vapour generator in dependence on a vapour temperature when this drops below a required level, and in dependence on the temperature at which reactor coolant leaves the vapour generator when this exceeds a required level. Power and coolant rate control.-The generated vapour pressure (e.g. superheated steam) is measured at 50, compared with a set-value signal 52, and the resultant signal used to determine control rod movement in the reactor 10. Reactor coolant temperature is measured at 60, compared with a set-value signal 62, and the resultant signal fed to a control unit 64 of the primary blower 14, whose speed is raised accordingly. Working fluid flow-rate is controlled by a servomotor 30, which moves the flow-rate valve 16. Temperature sensors 19 (vapour outlet) and 39 (coolant outlet from vapour generator) have their signals connected to hydraulic pressures which are fed to control valves 25, 45. The " required levels " of temperature are set on hand wheels 28, 48. When the feed rate to the vapour generator is too high, t 19  drops and piston 26 rises, thus causing servomotor piston 31 to descend and partially close the flow valve 16. When the feed rate to the generator is too low, t 39  rises and piston 46 rises, thus causing the servomotor piston 31 to rise and partially open the flow rate 16. It is of course important that the two control temperatures chosen are far enough apart to prevent simultaneous corrections being required of the system. In a modification (Fig. 3, not shown), three vapour temperatures are measured and averaged to control servomotor 25, which is ganged with the motor 45 to form one double-acting servomotor.

Abstract: 1,244,361. Analogue storage and delay circuits. FERNSEH G.m.b.H. 19 Sept., 1968 [19 Sept., 1967; 18 Oct., 1967; 18 Nov., 1967; 31 Jan., 1968; 3 Feb., 1968; 5 March, 1968], No. 44517/68. Heading H3U. In an analogue delay or storage circuit of the type in which signal samples are passed along a chain of charge storage elements, the elements are coupled by transistors in common control electrode configuration and series resistors. In Fig. 1, when a positive-going clock pulse is applied to the lower plate of capacitor 211 the capacitor charges to an extent dependent upon the analogue signal applied to resistor 214. When the clock pulse applied to the lower plate of a capacitor 221 goes positive the charge is transferred to 221. Thus charges are passed along the chain. A filter at the output may reconstitute the signal and a gate controlled by narrow clock pulses may precede the circuit to obtain instantaneous instead of average samples (Fig. 4, not shown). The transistor may be replaced by Darlington pairs or by field effect transistors. Charge stored in the transistors may be discharged by applying clock pulses to the transistor bases (Figs. 5 and 6, not shown). Instead of transferring charges together in a two-phase cycle they may be transferred one at a time in reverse order to increase the delay, a shift register being used for this purpose (Figs. 8-11, not shown). Charge storage diodes may replace the capacitors (Fig. 3, not shown).

Abstract: 1,089,688. Gas blast switches. BROWN. BOVERI & CO. Ltd. Oct. 6, 1966 [Oct. 8. 1965], No. 44758/66. Heading H2B. In a gas blast circuit-breaker having re-cycled sulphur hexafluoride for arc extinguishing, metal screening 18, 20 is arranged inside the insulator 14 between the live switch casing 1 and the earthed collecting vessel 16 and a flow of clean sulphur hexafluoride is directed between the insulator 14 and the screening 18, 20 during circuit breaking to prevent contamination of the inner surface of the insulator 14. In operation, pressure gas introduced at 6 initially causes retraction of a piston-valve sleeve 2, 3 which releases clean gas through gap 12 between an elbow pipe easing 11 and a hollow fixed electrode 9, 17 for scavenging the insulator 14. Apertures 21 in the support insulator 19 permit escape of the clean gas for scavenging between the screens 18, 20 and electrode 17. On further retraction of the valve 2, contact lamellµ 7 are withdrawn and the movable electrode 8 retracted by engagement of lugs 2a, 8a, whereby arc blast gases escape through the hollow fixed electrode 9, 17 and non-return valve 22 to the collecting vessel 16. The overlapping arrangement of screens 18, 20 protects the insulators 14, 19 from contact with the contaminated blast gas. The screen 18 further operates as a field control electrode between the electrode 17 and the earthed screen 20.

Abstract: 1419490 Heat exchangers K W COWANS 22 Dec 1972 [27 Sept 1971] 44982/71 Headings F4S and F4K In apparatus for heat exchange between two fluids (gases or liquids), impedance means are provided in the flow path for at least one of the fluids, said impedance means acting to counteract any variation in the fluid flow and to effect a generally uniform rate of heat exchange throughout said paths. The impedance means may, for example, Fig. 5, comprise a narrowing 76 (e.g. to 0À012 inch) in a central zone of a hot gas passage 70 with a corresponding widening at 84 (e.g. to 0À026 inch) in the cooler gas passage 82 wherein the impedance means comprises a narrowing (e.g. to 0À012 inch) at the ends 85, 86 of the passage. The passage walls may comprise either solid material or the boundaries created by electric or magnetic fields. In a heat exchanger for liquids the position is reversed in that the hotter liquid will flow through the passage 82 and the cooler liquid through the passage 70. Figs. 3 and 4 show a counterflow heat exchanger comprising alternate corrugated and flat sheets of plastics material providing passages 52 for the respective heat exchanging fluids A and B. The impedance means such as shown in Fig. 5 are provided either in both sets of passages A and B, or alternatively (see Figs. 6 and 7, not shown) in either the passages A or the passages B. In an alternative heat exchange structure with passages arranged as at 52 in Fig. 4, wire mesh screens are stacked and form the means of conveying heat between the fluids A and B, and the passage walls are formed by plastics material barriers penetrating the screens. This construction is said to be applicable also to regenerative heat exchangers.
