Title: Nuclear reactor charge/discharge arrangement
Inventor: BLUNT FRANCIS IVOR
IPC: G21C19/16
Filed: 1968-07-04
Abstract: 1,273,977. Fuelling reactors. BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd. 17 June, 1969 [4 July, 1968], No. 31972/68. Heading G6C. A reactor comprises a core formed of vertical columns made of moderator blocks, coolant fluid flowing through channels in the blocks in which fuel elements are supported. The columns are arranged in juxta-posed groups on, e.g., a triangular lattice and each group is associated with a centrally-disposed standpipe. In a fuelling arrangement for such a reactor an entire column is transferred through the associated standpipe. As shown in the drawing the columns are of hexagonal cross-section (Fig. 1, not shown) and each group comprises a centre column 1, receiving a control rod, surrounded by six columns 3 receiving fuel elements. Fig. 2 shows a standpipe 7 (from which a closure plug has been removed) and a fuelling device has been lowered through the standpipe so that a locating peg 29 seats in a channel 2 in the centre column 1. The fuelling device comprises a support tube 9 which may receive a guide tube 11, the latter having a hexagonal cross-section and being of such length as to accommodate an entire column. Links 12 connect the tubes 9, 11 and the tube 11 may be moved through an opening 28 in the side of the tube 9 to the displaced position, shown, in which it is aligned with a column 3. The particular column 3 is selected by rotating the device. Lateral displacement of the tube 11 is controlled by a link 26 connected to an actuator rod 27 movable in a guide 25 fixed to the tube 9. This lateral displacement is arrested by the chamfered lower end 19 of the tube 11 engaging the upper ends of those columns immediately adjacent the selected column and this engagement causes the adjacent columns to be urged away from the selected column to facilitate its removal. The fuelling device also includes a cable 13 extending from a winding drum (not shown) over pulleys 14, 15 to a plate-like member 16 slidable within the tube 11, the member 16 carrying a probe 17 having at its bottom end a latching device 21. The lower end of the probe 17 is guided by a plate-like member 18 slidable in the tube 11. The probe 17 is lowered by the cable 13 through a central channel 6 in the selected column 3 and the device 21 is operated to engage the lower end of the column. The cable is rewound and the column 3 is raised into the tube 11, this action lifting the member 18 against the member 16. The tube 11 is withdrawn into the tube 9 and the fuelling device is lifted through the standpipe 7. Holes 22, 23, 24 permit flow of the coolant fluid during the fuelling operation.

Patent GB-389908-A (GB)
Title: Improvements in and relating to electric time-measuring and time-switching devices
IPC: G04C15/00
Filed: 1931-11-18
Abstract: 389,908. Time switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Nov. 18, 1931, No. 32016. Convention date, Nov. 18, 1930. [Class 38 (v).] A clock or time-switching mechanism (e.g. a switch-clock or time-relay) having a synchronous motor 1 and a spring (or equivalent) driving device, may be driven (1) directly by the electric motor or (2) by the spring, manuallyoperated control means 13, 15 being provided for changing from one drive to the other. When the electric motor drives directly, it keeps the spring wound up and the latter comes into action on cessation of the current. In the second case the motor 1 keeps the spring wound also. The driving shaft 4 of the self-starting motor 1, 2 has a gear 23 engaging a wheel 6 loose on the minute arbor 10. Also loose on this arbor is a wheel 5 connected by pinion 17 with the escapement of the auxiliary mechanism, of which 20 is the balance. Wheels 5, 6 form overtaking couplings which operate the wheel 7 rigid with arbor 10. Integral with gear 23 is a cam 8 which raises and lowers an arm 9 about pivot 24; to the other end of arm 9 are pivoted (1) a link 18 winding up the spring barrel 19 of the auxiliary clockwork and (2) a link 11 which rubs against the axis of the balance 20 so that the balance is constantly rotated to keep it in order. Rigid with an armature 22, pivoted at 25 and attracted by a stator pole against the action of a spring 26, is a bell crank 12 having a pin 12<1> which coacts with arm 11. Whilst current is flowing the motor drives the minute arbor 10 through members 23, 6, 7 : but when current fails, spring 26 raises armature 22 so that bell crank 12 removes arm 11 from balance 20 and the auxiliary mechanism 20, 19, 17 drives the arbor 10 through coupling 5, 7. To drive arbor 10 by the auxiliary mechanism, whilst current is flowing, a cam 15 on axis 13 is manually rotated to rock arm 12 and remove link 11 to free the balance. At the same time cam 15 shifts a lever 21, which latter moves a gear 23, in opposition to a spring 16, out of engagement with wheel 6. Cam 8 is of such width, however, that it still oscillates link 18 to keep spring 19 wound. Means, such as a contact or arbor 10, may periodically interrupt the motor circuit for any desired duration to prevent the parts such as lever 12, from becoming stiff.

Title: Monostable multivibrator circuit
Inventor: SCHNABEL HANS
IPC: H03K3/284
Filed: 1967-07-12
Abstract: 1,148,146. Transistor monostable circuits. STARKSTROM-ANLAGENBAU ERFURT VEB. 12 July, 1967, No. 32107/67. Heading H3T. A monostable multivibrator comprises a pair of cross-coupled transistors 1, 3 and a timing circuit connected to the output electrode of transistor 1; the timing circuit including a capacitor 2, means 9 for presetting the duration of an output pulse, and temperature compensation means for maintaining the preset pulse duration by controlling the charge stored on capacitor 2 during the stable period of the multivibrator. In the stable state, transistor 1 is non-conductive, transistor 3 is conductive and capacitor 2 is charged in the circuit 12, 14, 2, 10, 11. A negative input signal at E to transistor 1 triggers the circuit, cutting off diode 10 and transistor 3 and switching on transistor 1. Capacitor 2 then discharges through the path 8, 9, 2 and transistor 1 to deliver a negative pulse at A, until diode 10 again becomes conductive so that the circuit returns to its stable state. The pulse duration is controlled by adjustable resistor 9. A negative temperature coefficient resistor 16 controls the conductivity of transistor 17 and hence the potential at the junction of capacitor 2 and resistor 14 and to which capacitor 2 charges during the stable period. Zener diode 13 stabilizes this potential against source potential variations. Potentiometer 14 permits adjustment of the temperature compensation to provide optimum conditions, or for compensating for temperature variations in preceding or succeeding circuitry, so that the duration of the pulse at the output of the overall system is maintained.
