Title: Improvements in or relating to nuclear reactors
Inventor: GRIFFIN JOHN RENNIE
IPC: G21C1/30
Filed: 1961-06-26
Abstract: 934,242. Producing neutrons. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 21, 1962 [June 26, 1961], No. 23119/61. Class 39 (4). A radiation shield for a neutron source comprises a liquid retaining capacity arranged between the source and a radiation facility, a supply of liquid having a large absorption crosssection for neutrons, and means for passing the liquid between the supply and the liquidretaining capacity. The drawing shows a vertical cross-section of a neutron source reactor comprising a core 1 surrounded by a number of caves. Between the core and each of the lateral caves 2, 3 is a two-part neutron and gamma shutter 6 operated in guillotine fashion as shown; each shutter 6 consists of two composite slabs of lead, synthetic plastic sheeting and cadmium suspended on roller chains to form a balanced system. Above the core is a rotatable lead shield plug 9 provided with a number of plugged holes (not shown) to give access to the core from the upper cave 4. The neutron shutter for the upper cave comprises a tank 10 adapted to be filled with liquid neutron absorbent (e.g. aqueous boric acid solution) by a pump 14 from a header tank 13. If the liquid in tank 13 has sufficient head the filling of tank 10 can be made automatic if the pump fails. Normally the tank 10 is filled, but it is emptied when the cave 4 is to be irradiated and refilled after the required exposure. Whilst emptying and filling the intensity of radiation in the cave 4 changes, but does so uniformly across the whole area of the cave.

Phases (1) and (2) may be carried out continuously, or phase (1) may be carried out continuously or non-continuously and phase (2) non-continuously. Suitable aromatic dicarboxylic acids are p,p<SP>1</SP>-dicarboxylic acids of the formula HOOC-C 6 H 4 -(R) n -COOH where n is 0 or 1, R is a C 1 -C 8  alkylene radical, -C 6 H 4 -, -R 1 -C 6 H 4 -, -O-R 2 -C 6 H 4 - or -O-R 3 -O-C 6 H 4 - radical where R 1 , R 2  and R 3  are C 1 -C 8  alkylene radicals; or naphthalene dicarboxylic acids. The preferred acid is terephthalic acid and the preferred glycol is ethylene glycol. Suitable sulphonate-containing compounds, of which the bis glycol esters are used, are compounds of the formula wherein X is an arylene radical, M a metal atom, the groups SO 3 M being separated from esterforming units by at least 3 carbon atoms, x = 1 or 2, Y and Z are oxyalkylene, oxyarylene, oxyalkylene - oxyarylene or poly - (oxypolymethylene)-oxyarylene radicals, y and y<SP>1</SP> are 0 or 1, n and n<SP>1</SP> are 0-10, A is COOH or COOR, where R = C 1 -C 6  alkyl, B is A or hydrogen, r is 1-2, with the proviso that when r is 1, then B must be selected from A, and when r is 2, then B must be hydrogen.

Abstract: 189,851. Willis, L., G., (Neff, E. D.). Sept. 2, 1921. Projectors; mounting electric lamps in lanterns. -Relates to apparatus attachable to guns for projecting a concentrated beam of light on to the target, and of the type comprising front and rear parts 16, 15, Fig. 2, hinged together and provided with vent openings 62, the front part 16 tapering towards an opening 60 which constitutes a stop for the beam. According to the invention, the source of light 48 is adjustably mounted in a special manner at the focus of an ellipsoidal mirror 38, the reflected rays from which converge to the other focus 59 and are concentrated into a parallel beam by a lens 58, the rays which do not intercept the reflector being also brought to a focus at the point 59 by an auxiliary lens 61. By means of a block 47, the lamp 48 is adjustably mounted within a cap 40 screwed to the rear of the lamp. Longitudinal sliding adjustment of the lamp-socket 52 within the block 47 is effected by a screw 54 and spring 53, and the block itself is adjusted transversely in two directions at rightangles to one another by four screws 47a engaging bevelled surfaces on the block. The block is guided in its movements by a cross-shaped member 43 the limbs of which engage grooves in the cap and also grooves in the block at right-angles to the cap grooves. The spring 53 serves to cushion the lamp when the gun is fired.

Abstract: Condensation products for use in the manufacture of lacquers are prepared by condensing urea or thiourea or derivatives or mixtures with formaldehyde or substances with like action in the presence of basic condensation agents and in the presence of a considerable proportion of water and of an organic solvent or mixture of organic solvents.  Water may be removed by distilling off a mixture of water and organic solvent and replacing it by organic solvent or such a proportion of water and solvent may be used that the resin has a minimum solubility and may be readily removed.  Suitable organic solvents include esters such as formates and acetates.  In examples: (1) a mixture of urea and thiourea is condensed with aqueous formaldehyde in the presence of glycol monoacetate, soda lye and sodium carbonate a mixture of water and glycol acetate being distilled off and replaced firstly by a mixture of glycol and glycol monoethyl ether and then by a mixture of glycol mono-methyl and mono-ethyl ethers to yield a lacquer; (2) a mixture of urea and thiourea is condensed with aqueous formaldehyde in the presence of ethyl acetate and soda lye to yield a resin which separates on cooling.  Ammonium sulphate may be added to accelerate the separation of the resin.  Colouring materials, fillers such as lithopone, titanium white or zinc white, and plasticizers such as cellulose ethers or polyvinyl compounds may be added to the lacquers.
