Title: Backup Control Rod System.
IPC: G21C9/02
Filed: 1969-06-13
Abstract: 1,193,060. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 13 June, 1969 [16 July, 1968], No. 30142/69. Heading G6C. During normal operation of a reactor, a back-up control rod 13 is maintained in a position beneath the reactor core 10 by suction produced, for example, by an electromagnetic pump 21. Upon failure of the primary control system or other desired shut-down of the reactor, the pump 21 is reversed or inactivated and the control rod 13 is allowed to float upwardly into the core 10 due to it being less dense than the coolant, e.g. sodium, in the core. The reverse flow from the pump 21 may be utilized to force the rod 13 into the core. A primary control rod 12 is moved via a drive shaft 14 which extends through an aperture 15 in a guide tube 11 housing both control rods 12, 13. A piston 16 integral with the lower end of the backup control rod 13 is normally located within an upwardly projecting cylinder 17 formed in the lower end 18 of the guide tube 11. An aperture 19 in the lower end 18 provides fluid communication between the cylinder 17 and a conduit 20 Heading to the reversible electromagnetic pump 21. In addition, the lower end 18 is provided with at least one coolant orifice 22, whereby coolant can flow through guide tube 11 via orifice 22 and aperture 15. During normal operation of the reactor, the backup control rod 13 is held with the piston 16 within the cylinder 17 by suction produced by the pump 21. Scram action of the rod 13 is initiated by inactivation or reversal of the pump 21. The rod 13 floats upwardly in guide tube 11 until it contacts the primary control rod 12. The rod 13 is returned to its normal position by lowering the rod 12 to push rod 13 down so that it can again be held by the suction of pump 21 on piston 16 within cylinder 17. In the event that the primary control rod 12 scrams, the initiating mechanism for the backup control rod 13 may also be simultaneously initiated. In such a case, the speed of the primary rod 12 will be such that it will prevent the backup rod 13 from achieving full stroke, rod 13 not being needed in such case but having been activated should a full downward stroke of the rod 12 not be accomplished, thus assuring faster operation of the rod 13. A snubber can be incorporated between the rods 12, 13 to prevent impact, this being in the form of either a short projection on one rod which enters a recess in the other, or a spring secured to one of the rods.

Title: Electric remote control system
IPC: B61L7/06
Filed: 1959-09-04
Abstract: 866,175. Control of A.C. motors. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. STIN. Sept. 4, 1959 [Sept. 5, 1958], No. 30207/59. Class 38 (3). [Also in Group XXX] Relates to a remote control system for a reversible two-phase motor M regulating the position of railway switch points, wherein the motor is connected to the controller through four leads L1-L4. When the motor is at rest in the position shown, half-wave supervisory current passes from supply terminal S to neutral N through motor windings Ml, M2, relay coil H, and rectifier V. The rectifier is shunted by choke B4, one winding section of relay B3, and indicating relay NR, so that alternate halfwaves pass through these elements. Energization of relay NR indicates the continuity of all the components through which the supervisory current passes, including the motor windings and the four leads L1-L4. When the points are to be changed-over, relays E, F and G are energized, the supervisory current is cut-off, and relay H is de-energized to isolate indicating relays RR, NR from lead L2. Current passes from terminal P1 through motor winding M2 and winding Y of auto-transformer B5 to neutral, phase-displaced current passing from terminal P2 through motor winding M1 and transformer winding X, whereby the motor is energized to move the driven element T away from its end-position. Relay B3 is connected across leads L2, L3, in series with choke B4 and in shunt with rectifier V, but, since the relay is polarized, it does not respond at this stage. When contact N engages contact N2, the leads L2-L3 are connected directly until contact R engages contact R2. The relay B3 is now energized in the reverse direction and becomes effective to stop the motor. Since contacts N, R carry only the supervisory current, they may be of light construction and totally enclosed in a vacuum or protective gas.
