Title: Method of stabilization of the power of a liquid-moderated liquid-cooled nuclear reactor
IPC: G21C7/26
Filed: 1969-12-22
Abstract: 1,234,914. Controlling reactors. ELECTRICITE DE FRANCE (Service National). 22 Dec., 1969 [24 Dec., 1968], No. 62317/69. Heading G6C. In a heavy water moderated, steam generating nuclear reactor, control is effected by the formation of steam voids in the moderator to compensate for instabilities caused by the positive void coefficient of the coolant water. A rise in reactivity in a fuel channel increases the coolant steam void volume and produces a further reactivity increase. The resultant rise in heat transmitted to the surrounding moderator causes the formation of steam voids in the moderator which reduce the moderation action and the reactivity of the adjacent region. The heavy water moderator, in calandria tank 1, is boiled by the heat generated in the fuel elements 6, in the tubes 2, cooled by the flow of boiling water. Moderator steam is condensed in the heat exchanger 22, and returned to the calandria by the pump 34, which regulates the moderator level.

Abstract: 715,617. Ticket-issuing machines. WESTING- HOUSE GARRARD TICKET MACHINES, Ltd., DIXON, S. M., and DAVIES, J. E. March 10, 1952 [May 1, 1951], No. 10186/51. Class 106 (3) A machine for issuing tickets and the like comprising a train of gears driven by an operating handle to cause the issue of a ticket on each cycle of operation, at least one gear being rotated through at least two complete revolutions for each cycle, an abutment rotating with said one gear and a locking lever at times moved into engagement with the abutment by the displacement of another , member thereby preventing the operation of the machine is characterized by a stop member and means responsive to the initiation of a cycle of operation to move the stop member to the operated position wherein' it prevents the engagement of the abutment by the locking lever during a complete cycle. A drum 32 is rotated for one revolution through the gears 33, 37 by a manually operated lever 35 to print and issue a ticket. The drum 32 is normally locked by the nose 29 of a pivoted lever 27 entering a recess 31 in the periphery of the drum 32. The hub 34 of the gear 33 has a notch 36 which may be engaged by the arm 10 and/or the arm 13 of two double armed levers 9, 12 pivoted on a common spindle 11. The lever 9 is connected to one end of a link 5 which is controlled by a key operated lock 1 so that its end 41 may lock the bolt 40 of the pivoted door 38. The lever 12 is connected by a link 17 to a pivoted bell crank lever 14 which co-operates with a pin 19 controlled by the box 20 and the audit strip therein. Before the machine is operated the bolt 40 is moved and locked by downward movement of the link 5 when the lock 1 is actuated. The downward movement of the link 5 disengages the lever 9 from the notch 36. To issue a ticket the nose 29 of the lever 27 is disengaged from the recess 31 by momentary depression of a finger piece 42. A stop member 22 isthereby moved through the link 25 and the spring 25B to engage the levers 9, 12 and retain them in their inoperative positions; If, during a machine cycle, the audit strip breaks or runs out and/or if the box 20 is moved one or other or both of the levers 9, 12 will be freed from the stopping member 22 to move into engagement with the notch 36 when the nose 29 again engages the recess 31 so preventing the starting of another machine cycle. Continuous depression of the finger piece 42 would, however, prevent the stopping member 22 from freeing the levers 9, 12. To avoid this drawback the stopping member may be controlled by a cam rotating coaxially with the drum, Fig. 2 (not shown).
