Title: Improvements in and relating to nuclear reactor plant
IPC: F22B35/00
Filed: 1964-09-01
Abstract: 1,005,850. Nuclear power plant. SULZER BROTHERS Ltd. Sept. 1, 1964 [Sept. 13, 1963], No. 35797/64. Heading G6C. [Also in Divisions F1 and G3] Control of a reactor plant, in which reactor coolant transfers heat to two separate prime mover circuits, is achieved by adjusting the flow rates of the two prime mover circuits in accordance with the temperature of primary coolant entering the reactor, and by adjusting the individual flow rates of the two prime mover circuits in accordance with vapour pressures. The reactor 10 is gas-cooled, the prime mover circuits 11, 11<SP>1</SP> contain water, steam and superheated steam, and the prime movers are steam turbines 14, 14<SP>1</SP>, driving generators 18, 18<SP>1</SP>. Gas is circulated down through the core and over a twinrun heat-exchanger 6, 6<SP>1</SP> by a blower 7. The primary coolant temperature is measured by a sensor 34, and steam pressures in the circuits 6, 6<SP>1</SP> by orifice plates 12, 12<SP>1</SP> and diaphragm units 55, 55<SP>1</SP>. If the temperature of reactor coolant as sensed by sensor 34 rises, the piston of servomotor 32 is depressed, thus displacing fulcrum 47 of bell-crank lever 31, which, through rods attached to levers 30, 30<SP>1</SP>, opens flow regulators 22, 22<SP>1</SP> by equal amounts; this increases the secondary coolant flow rates and results in the required gas coolant temperature being re-established. Clearly, a drop in gas coolant temperature will also be corrected, in a similar manner. The live steam pressures in the two steam lines are equalized by two systems, one for each line, which rocks the bell-crank lever 31 about its pivot 47 to give equal and opposite movements of the flow regulators 22, 22<SP>1</SP>. Thus, each line 52 supplies a pressure to valve 37 which in turn controls the position adopted by piston and rod 31, and hence the angular displacement of lever 31. Reactor control rod is moved by a motor 41 in response to signals from a control unit 40 which sums the steam pressures in the lines 11, 11<SP>1</SP> and compares the sum with a valve pre-set on a controller 42. The control rods are moved to tend to equalize the sum and the set value. Two further control systems are provided, firstly to run the auxiliary turbines 26, driving circulating pumps 20, at a speed corresponding to the setting of the flow regulators 22, and secondly to adjust the flow regulator openings accordance with the mass flow rate of steam in each line 11. The detailed operation of these control systems if self-evident from the drawings. Steam circuits.-(They are identical, and only one is described hereafter). Steam, preferably superheated, is fed to a turbine 14 and exhausts to a condenser 15. Condensate pump 16 passes the water through two preheaters 17, heated by steam bled from the turbine. Preheated water from a reservoir 18 is fed by the pump 20 to a further preheater 21, and then to the regulator 22.

Title: Hydraulic packaging press
IPC: A24B1/10
Filed: 1962-09-24
Abstract: 1,005,198. Packing compressible material. F. B. FISHBURNE. Sept. 24, 1962, No. 36252/62. Heading B8C. A press for packing loose, compressible material into containers, e.g. tobacco into hogsheads, comprises a power-operated plunger 7 arranged to enter a charger 14 and compress material therein, a distributer 13 for filling the charger 14, means connected with the plunger 7 for shifting the distributer 13 out of the path of the plunger during the initial movement of the plunger towards the charger 14 and into the path of the plunger during the final part of the movement of the plunger away from the charger, and means for retarding the initial movement of the plunger. The distributer 13 which rotates in a horizontal plane to distribute the material evenly is mounted on a hopper 10 which is arranged to move horizontally by means of rollers 11 engaging a track 12a. Material is delivered to the hopper 10 by an endless conveyer 15. To a horizontal shaft 16 supported by fixed members (not shown) are rigidly secured two arms 17 which are pivotally connected to a pair of links 19 which in turn are pivotally connected to members 20 on the hopper 10. Also rigidly attached to the shaft 16 are two arms 21 having cam tracks provided on their inner faces by guides 23, 24. Two tubes 25 secured to the plunger 7 carry rollers 27 which engage the cam tracks. The plunger 7 is carried by a piston rod 6 in a hydraulic cylinder 4. When the plunger 7 and the hopper 10 are in the position shown in full lines and the charger 14 is sufficiently full, fluid is admitted to the upper end of the cylinder 4 and the plunger begins its downward stroke. The tubes 25 also move downwards and the rollers 27 swing the arms 21 and hence the shaft 16 and the arms 17 until the hopper 10 has been shifted to the position shown in dotted lines. The plunger 7 continues its downward stroke, the rollers 27 escaping from the cam tracks. The plunger is raised by admitting fluid to the lower end of the cylinder 4, the rollers 27 engaging the cam tracks and returning the hopper 10 to its original position. The initial downward movement of the plunger 7 is slowed down to reduce the shock on the hoppershifting mechanism by restricting the flow of fluid (Figs. 6-9, not shown). A switch 34 is operated by the hopper 10 when in its inoperative position to enable the plunger to complete its downward stroke at normal speed. A pair of plungers and chargers are adapted to operate together. In a modification (Figs. 10, 11, not shown) the hopper is moved by a piston operated within a cylinder by a source of compressed air which is controlled by a four-way valve. The piston of the valve carries a roller which bears on a cam mounted on the tube 25.
