Title: Improvements in or relating to nuclear reactors
Inventor: COTTRELL ALAN HOWARD
IPC: G21C5/04
Filed: 1958-07-15
Abstract: 895,892. Moderators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 3, 1959 [July 15, 1958], No. 22585/58. Class 39(4). To reduce Wigner energy accumulation in a graphite moderator the moderator temperature is raised by confining the coolant to tubes inside and spaced from the walls of the fuel channels, to reduce heat transfer from moderator to coolant. The tubes may be of graphite, Mg, Be, BeO, Zr or SiC. Fig. 2 shows a column of graphite blocks and tiles pierced by a channel 16 containing fuel elements 5. A support unit 4 set in the base of the column carries a spider 21 integral with a tube 23 having labyrinth sections 24; sockets at 27 in the tube support further tubes. The spider supports the fuel elements. The labyrinth sections reduce gas flow in the annulus 18 and so provide thermal insulation. In another embodiment (Fig. 1, not shown) the annulus is sealed and the principal leakage path at the tiles 3 blocked by graphite collars. Specifications 783,094 and 784,292 are referred to.

Title: An improved self-induction coil pair for loading telephone lines
IPC: H01B11/16
Filed: 1921-08-25
Abstract: 174,320. Felten & Guilleaume Carlswerk Akt.-Ges. Jan. 17, 1921, [Convention date]. Inductances. - Fig. 1 shows a known form of loading-coil used to load a metallic circuit a, b. If the conductors a, b are used also jointly as one conductor of a superimposed or duplex circuit in a four-wire line, so that the currents pass in the same direction, as shown by the double arrows, the correct ratio between the main self-induction and the duplex self-induction is secured, according to this invention, by winding some cross or neutralizing turns as shown in dotted lines in Fig. 2. The ring being provided with a bridge-piece (not shown) to take the flux between the poles n, s formed by the duplex circuit, the inductance for the main line is proportional to N-n, where N is the number of main turns, and n the number of cross turns, whereas the inductance for the duplex line is proportional to N+n. The ratio of the inductances in the two circuits can thus be given any required value.

Title: A gripper for a loading machine of a nuclear reactor
Inventor: JOHNSSON ERIK BORJE
IPC: G21C19/105
Filed: 1966-05-20
Abstract: 1,148,663. Grippers for lifting nuclear fuel elements. ATOMENERGI A.B. 20 May, 1966 [24 May, 1965], No. 22630/66. Heading B8H. To raise a fuel element 6 from a channel a gripper is lowered by a wire 21 and as it moves downwards a spring-loaded lever 4 is rotated by a shoulder 7b so that a projection 19 is withdrawn from an annular groove 28 in an inner member 2. This frees the inner member 2 with respect to an outer member 1 so that when the outer member has been lowered to its furthest extent the inner member 2 may be lowered and raised again. A pin 15 co-operating with a slot 22 in the inner member rotates the latter through 60 degrees. As a result of this rotation shoulders 8 push three hooked jaws 3 into engagement with hooks 9 on the fuel element. The element may now be lifted and as a roller 18 moves over the shoulder 7b the projection 19 re-enters the groove 28 and locks the inner and outer members together thereby locking the jaws 3 in their operative position. When the element is set down reciprocation of the inner member 2 again causes rotation through 60 degrees to bring shoulders 12 into engagement with the upper ends of the jaws 3 to hold them in their inoperative position. A ratchet and pawl mechanism 26, 27 ensures that the inner member always rotates in the same direction.

Filed: 1932-08-12
Abstract: 388,316. Force - feed lubricating. NEMETZ, G., 21, Marxergasse, FRIEDMANN, L., FRIEDMANN, M., and .SCHOPP, N., (trading as FRIEDMANN, A.), 6, Am Tabor, both in Vienna. Aug. 12, 1932, No. 22652. [Class 12 (iii).] Oil supplied under pressure to the verticallyarranged chamber 2 of a casing 1 through a pipe 4 connected thereto at the bottom lifts a loosely-fitting ball 3 arranged within the chamber until it closes an outlet passage 7, a spring-loaded non-return valve 8 being arranged above the passage 7, whereby a predetermined quantity of oil is delivered to the part to be lubricated. When the supply pressure is relieved, the ball 3 falls to its lowermost position and the valve 8 closes. The closing movement of the latter creates a back pressure in the passage 7 tending to dislodge the ball 3, and this effect may be increased by forming the valve with a piston-like projection 11 adapted to enter the passage 7. Alternatively, the valve may have an extension adapted to contact with and positively dislodge the ball ; or the length of the passage 7 may be so small that the valve 8, constructed as a ball, is itself adapted to contact with the ball 3 ; or the ball 3 may be dislodged by a separate spring.

Abstract: 738,481. Filters. BLAKEBOROUGH & SONS, Ltd., J., and BROTHERTON, C. Dec. 5, 1950 [Sept. 9, 1949], No. 23331/49. Class 46. [Also in Groups XXXV and XXXVII] Means for auto. matically setting in motion cleaning means for a stationary screen for liquids, or for giving an indication that continuous cleaning of a travelling band screen is not being adequately maintained or is not being performed, comprise a container connected to the approach channel of a stationary screen, or to the upstream side of a travelling band screen and a further container connected to the screen chamber or to the downstream side of a travelling band screen, the containers having disposed therein cylinders which are responsive only to a differential rise or fall in the level of the liquids and whose movement is adapted to actuate the cleaning or indicating means, means adapted to discharge water from each cylinder into each container respectively to maintain the head of water therein above that in that part of the liquid way connected thereto, and the arrangement being such that a continuous flow of water from each cylinder along its connection into the liquid way is maintained. Standpipes a and b, Fig. 1, are connected respectively to the approach channel and screen chamber of a stationary screen and have within them opentopped hollow cylinders a<SP>1</SP>, bl respectively, suspended by cables from either end of a beam e, Fig. 3, rocking on knife-edged pivots f. A rise in level in the screen chamber results in a rise in level in the standpipe b and consequently of the cylinder b<SP>1</SP> until an adjustable abutment g on the cable b<SP>2</SP> engages a pivoted lever h to tilt a mercury switch i, which through one or more relays sets the screen cleaning means in operation. Choking by solids of the piping d (not shown) and c connecting the standpipes to the channel and chamber is obviated by maintaining a flow from-the standpipes through the piping. This is brought about by a flow of water from jets which causes the cylinders to overflow continuously and maintains a level in the standpipes slightly higher than that in the channel and chamber respectively. For use with a travelling band screen the cylinder b<SP>1</SP> is connected with the downstream side of the screen and the cylinder a<SP>1</SP> with the upstream side. The abutment g is placed above the lever h instead of below it so that choking of the screen will be followed by a fall of level in the standpipe b, and tilting of the switch i to actuate an alarm. Means k, k, Fig. 3, are provided to enable the effective length of cables a<SP>2</SP>, b2 to be adjusted so that the degree of differential action to which the control or indicating means will be responsive may be varied.
