Title: Improvements in or relating to nuclear reactors
Inventor: DALE WALTER BERNARD
IPC: G21C7/10
Filed: 1967-03-08
Abstract: 1,133,427. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 Feb., 1968 [8 March, 1967], No. 11017/67. Addition to 1,093,029. Heading G6C. A nuclear reactor has control elements of large neutron absorbancy for normal control and shutdown functions and additional control elements of small neutron absorbancy intended for deep insertion in the reactor core during full power operation for controlling the excess reactivity provided for xenon over-ride and for operation by auto - control where provided, each additional control element being in co-positional relationship with a control element of large neutron absorbancy and each telescopically cooperating with a further control element of small neutron absorbancy which is captive on the respective additional control element. As shown in Fig. 2, a control rod 14 of conventional construction fits with clearance within a control channel 1, being suspended by a chain 10<SP>1</SP> by means of which it can be inserted into or withdrawn from the channel 1 from a winch unit (not shown). The length of the control rod 14 is <SP>2</SP>/ 3  to ¥ the core height, and the rod 14 carries at its lower end an additional control rod 15 of such length that the total rod length equals the full core height. The rod 15 is of smaller diameter than the rod 14 and has an external flange 16 at its lower end which fits with clearance within the bore of a tubular further control element 17 provided with an internal flange 18 at its upper end. The length of the element 17 is the same as that of the rod 15. A support stool 19 supports the closed lower end of the element 17 level with the bottom of the core 2. The rod 14 is of high absorbancy for thermal neutrons ("black"), and the rod 15 and the element 17 of small absorbency ("grey"). When the rod 15 is wholly within the element 17, their total absorbancy is of a value approaching "black" and withdrawal of the rod 14 progressively exposes the "grey" rod 15 and reduces the "blackness" of the element 17. When the flange 16 reaches the flange 18. between <SP>2</SP>/ 3  and ¥ of the assembly will be "grey" from the bottom of the core. Further withdrawal raises the element 17, leaving no absorber at the lower end of the channel 1 and progressively reducing the amount of "black" absorber at the upper end of the channel. It may prove desirable for the rod 15 to have its absorbanoy for thermal neutrons to be somewhat increased, but not to fully "black", by incorporation therein of a suitable material such as cobalt.

Patent GB-444440-A (GB)
Title: A process for the production of polymerised oils
Filed: 1935-04-12
Abstract: Fats and fatty oils are polymerized by heating in presence of a heavy metal dispersed electrically in an organic medium miscible with the oil or fat.  Dispersions of cobalt, iron, manganese, lead, nickel, chromium, molybdenum, or tungsten, in butyl alcohol, propyl alcohol, turpentine, or mineral spirits are suitable; but the oil itself may sometimes be used as the dispersion medium. Drying, semi-drying, or non-drying oils, or mixtures thereof may be treated, usually at atmospheric pressure and in an atmosphere of carbon dioxide, and usually for such a time that the metal dissolves completely whereby, in the case of a drying oil, the drier is produced direct.  The products may be used for coating solid surfaces or as binding agents in moulding mixtures.  In an example, cobalt is dispersed in butyl alcohol by an oscillating discharge, and so much of the dispersion added to linseed oil that 0,01 per cent of cobalt relative to oil is present; the mixture is heated to 530 DEG  F. for 8 hrs. under a stream of carbon dioxide. Other examples describe the treatment of a mixture of linseed and wood oils in presence of manganese dispersed in propyl alcohol, of partially polymerized soya bean oil in presence of iron dispersed in turpentine, of coconut oil in presence of cobalt dispersed in turpentine, and of castor oil.

Abstract: 791,365. Endless pusher conveyers. MORGAN CONSTRUCTION CO. April 16, 1956 [July 15, 1955], No. 11472/56. Class 78 (1). In a conveyer system wherein articles, e.g. coils of metal rod, are moved by dogs on a first chain conveyer into a position where they are picked up by dogs on a second chain conveyer, the dogs on the first conveyer are retractable and a series of delay stations at which the dogs can be retracted is located in advance of the position at which the articles are picked up by the dogs on the second conveyer, control means being provided whereby if one of the delay stations or the pick-up position is occupied by an article the dog at the preceding delay station is retracted. As shown, there are two first and two second conveyers, each conveyer comprising a pair of chains. The first conveyer chains 16, 17 are fed at irregular intervals with coils of rod from pouring reels 11, 12, laying reels 13, 14 or coarse pouring reels 15. The coils are fed by pivoted dogs 22 on the chains 16, 17 to delay station C where they are transferred by a dog 34 on each of two transfer chains 33 into positions where they are picked up by dogs (not shown) on respective second conveyer chains 18, 19 which in turn deliver them to a transfer conveyer 20 adapted to place them on hooks on a further endless conveyer 21. The chains 18, 19 and 20 are arranged to supply all the hooks on conveyer 21 with a coil, the dogs on the conveyers 18, 19 being out of step so that coils pass alternately from the latter to the chain 20. In order that each successive dog on chains 18, 19 shall receive a coil each of the conveyers 16, 17 is driven such that two successive dogs 22 reach position C every time a coil is removed from delay station C by the dog 34 and control means is provided for preventing successive dogs delivering to delay station C. The control means comprises switches 46, 47 closed respectively by coils at delay stations A, B positioned in advance of delay station C, and a further switch 45 operated by a cam on the shaft 39 of the sprocket around which the forward end of the chain 16 or 17 passes. Switch 45 is arranged to close each time dog 34 is approaching station C. As shown in Fig. 7, switches 45, 46 and 47 are connected in series with one another and with a relay 48 having holding contacts 49, which operate so long as switch 45 is closed, and further contacts 43 which when the relay is energized actuate a solenoid 42. As a result, solenoid 42 is energized, only when stations B and C are both occupied. Solenoid 42 controls dog-retracting mechanism comprising horizontal bars 25 along which the dogs 22 slide and which are normally arranged in register with a cut-away portion of tracks which support the dogs in raised position. The bars 25 are adapted to be lowered by hydraulic cylinders 32 which are controlled by a valve in turn controlled by the solenoid 42. The arrangement is such that when solenoid 42 is energized the bars 25 are lowered so that the coils at stations A and B remain in these positions until the coil at station C has been removed by the dog 34.
