Title: Improvements in and relating to systems of electric motor control
IPC: H02P5/50
Filed: 1930-01-11
Abstract: 342,493. Maintaining proportional speeds of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Horstkotte, E. H. ; 1318, State Street, Schenectady, New York, U.S.A.) Jan. 11, 1930, No. 1083. Convention date, Jan. 11, 1929. [Class 38 (iii).] Varying electromotive force.-Motors 11 for individual drives of a paper-making machine &c. are maintained at predetermined constant speed ratios while their speeds can be varied as a whole. Each motor has its field excited from a constant voltage exciter 21 and its armature supplied from a separate generator 12. The fields of each generator are supplied in parallel from a variable voltage exciter 23. By varying the resistance R1 of a motoroperated rheostat, the separately excited field of the exciter 23 is varied, and hence the speeds of the motors 11 are varied in unison. To maintain the desired speed ratio, the speed of each motor is compared through cone pulleys and belt 36, and a regulating machine 34 with a standard frequency supply 41. A variation in speed from normal causes operation of a rheostat 42 in series with the field of the corresponding generator to correct the variation. The frequency of the supply 41 must be increased when the speed as a whole is to be increased, and to this end, the alternator 31 feeding this supply is driven by a variable-speed motor 32 fed from a variable voltage generator 33 the field resistance R2 of which is varied in unison with the resistance R1. To keep the speed of the motor 32 constant at the value determined by the resistance R2, an associated tachometer generator 47 supplies a vibrating relay 48 which varies the excitation of an auxiliary exciter 28 in series with the field of the generator 33. The normal current through the relay 48 is maintained constant for any setting of the resistances R1 R2 by another associated variable resistance R3. Each motor 11 is started by a motor-operated starter 51, which first closes a field contactor 57 for the field circuit of the associated generator 12, then reduces to zero a resistance R5 in series with this field and finally closes a contactor 40 to connect the regulating machine to the supply 41.

Title: Improvements in or relating to nuclear reactors
Inventor: COAST GEOFFREY
IPC: G21C15/06
Filed: 1965-01-12
Abstract: 1,098,282. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 3, 1966 [Jan. 12, 1965; Sept. 29, 1965], Nos. 1318/65 and 41428/65. Heading G6C. A nuclear reactor with a pre-stressed concrete pressure vessel has one or more steam generating heat exchangers contained within the wall thickness of the pre-stressed concrete. In one embodiment (Fig. 7, not shown), a gas-cooled reactor has core 1 enclosed within a pre-stressed concrete pressure vessel 2 within the thickness of the walls 63 of which are cast-in steel shutter tubes 61 some of which extend parallel with the vertical axis X-X of the vessel. The latter tubes house eighteen heat exchangers 62 arranged on a single pitch circle. The pressure vessel 2 comprises a barrel portion C closed at the ends by bottom and top masses A and B respectively and is pre-stressed by vertical tendons 64 extending in the cylindrical wall, by circumferential tendons 65 around the barrel portion C and by tendons 66 extending along chordal paths in the bottom and top masses A and B respectively. The stresses set up by the tendons 65 are transmitted throughout the whole wall thickness of the barrel portion by means of ligaments 62a (Fig. 8, not shown) which extend between the shutter tubes 61. To protect the peripheral wall and the top of the pressure vessel chamber from the coolant at outlet temperature, a shroud 72 defines a space 73 for coolant between itself and the peripheral wall and top of the chamber. The shroud 72 is double-walled and is arranged for the passage of a small quantity of coolant from the inlet plenum 69. A baffle 74 between the shroud and the peripheral wall permits a small flow of coolant through the space 73 which is thus kept at substantially coolant inlet temperature. The chamber is lined with a water-cooled steel membrane 79 which ensures gas tightness and also a safe concrete operating temperature. Circulation of the coolant is effected by means of circulators 80 each of which comprises an electrically driven impeller 84 and a diffuser 85. Where the coolant enters the circulator it is drawn over a baffle 82 which screens the circulator intake from any liquid droplets which may become entrained in the coolant in the event of a heat exchanger leakage. Such droplets are incapable of following sudden changes in direction of the coolant. A central penetration is provided in the top mass B for a charge/ discharge machine together with numerous smaller penetrations 93 for control rod mechanisms. Several smaller penetrations 94 for introducing or discharging fuel assemblies are provided in the bottom mass A. In an alternative embodiment in which there are no circumferential tendons, the pressure vessel is surrounded by a shroud which forms a space surrounding the vessel which is kept at a pressure slightly below atmospheric so that, in the event of leakage of radioactive products through the vessel, those may be contained and safely discharged.
