Title: Improvements in and relating to the Manufacture of Chlorhydrins.
Inventor: KERFOOT THOMAS
IPC: C07C29/66
Filed: 1917-08-18
Abstract: 128,635. Kerfoot, T., Kerfoot, E. H., Irvine, J. C., and Haworth, W. N. Aug. 18, 1917. Chlorhydrins are prepared by supplying small amounts of hypochlorous acid and ethylene or its homologues &c. to a liquid medium, and repeating the operations until the resulting solution of chlorhydrin is sufficiently concentrated to be worked up. The process may be carried out by first passing chlorine into a copper salt solution to give a weak solution of hypochlorous acid (Specification 12912/15, [Class 1 (ii), Inorganic compounds other than &c.]), cutting off the chlorine supply when absorption ceases and driving off the excess chlorine from the reaction vessel by a stream of air, and then passing ethylene into the solution; the operations are repeated until the solution contains, eay, 40 grm, of chlorhydrin per litre. Stronger solutions may be obtained by periodically neutralizing the hydrochloric acid formed, e.g. by means of basic copper carbonate and continuing the operations. The chlorhydrin is then separated by fractional distillation or by extraction with ether, &c. During fractional distillation of the aqueous solutions, calcium carbonate may be added to neutralize hydrochloric acid. The product is finally purified by fractional distillation, washing with petroleum spirit, and drying. Ethylene dichloride is formed as a byproduct in the process. The process may be carried out on the large scale in packed towers through which the liquid circulates and comes into contact alternately with chlorine and ethylene, or in a tower divided by a series of shelves into zones containing alternately chlorine and ethylene, through which the liquid flows.

Title: Locating grids
IPC: G21C3/348
Filed: 1972-03-15
Abstract: 1386424 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 22 March 1973 [15 March 1972] 12162/72 Heading G6C A locating grid for a nuclear fuel assembly comprises a plurality of metal strips interconnected to form a plurality of walls arranged to contact each fuel pin at only two circumferentially separated locations which are not diametrically opposite one another, at least two such grids being displaced along the fuel assembly and suitably oriented relative to one another so that lateral movement of each fuel pin as a whole is substantially prevented. As shown, the metal strips 1 are bent at angles of 120 degrees and the compartments 2 each house two or more fuel pins 3 (with the exception of compartments 14, 15 which each house but one fuel pin). At each corner of the hexagonal perimeter of the grid there is located a hexagonal member 8 having a rounded outermost apex and a central hole 9. The walls of each compartment 2 form a regular part-hexagon, two of these walls each including an integral projection 10. The grid is braced either by means of metal strips 11 or by means of triangular metal filling pieces 12. An identical grid is spaced along the fuel pins 3 and displaced relative to the first grid by 180 degrees so that the two grids co-operate to complete, in plan, each hexagon and thereby wholly surround each fuel pin. The pins while being located against bodily lateral movement in any direction, are free to move relative to each individual grid, which movement is accommodated by the pins " snaking " slightly between grids. Although in the embodiment described the compartments are hexagonal, this is not essential and other geometrical figures, such as a square or rhombus, may be used. The compartments may even have curved sides. In an alternative form of the invention, the metal strips are bent and interconnected to form compartments each of which houses only one fuel pin, for example, closed hexagonal compartments such as the compartments 14, 15 in Fig. 1. The pin in each compartment is contacted by a pair of projections on one such grid and by an oppositely located pair of projections on an adjacent displaced and suitably oriented grid.

Each gripping unit 15 comprises gripping members 36, 36 co-operating with a supporting plate 26 and mounted by means of cranks 33 on a carriage 17 running on two pairs of wheels 19, 19<SP>1</SP>; 20, 20<SP>1</SP> in endless guide channels 14, 14<SP>1</SP> between rails 12, 12<SP>1</SP> and 13, 13<SP>1</SP>. The axle of wheels 19, 19<SP>1</SP> is pivoted to conveyer chains 4, 4<SP>1</SP> which are driven intermittently by a drive shaft 11, crank arm 10 and Maltese cross 9. At the collecting station A, the gripping unit 15 is held in an extended condition against the action of a spring by means of a roller 41 on one crank arm 33 co-operating with a guide rail 42 having a pivotal end portion 43 whose position is controlled by links 44, 45 and a thrust cam 46 on the drive shaft 11. When a preset number of bags has passed the counter 59, the drive shaft 11 is actuated, the rail 43 is withdrawn so that the hook members 36 grip the packet P, and holding fingers (40, not shown) are pivoted upwardly to hold the continuously-arriving bags on a depositing table (39) until another gripper unit 15 is at station A. At an intermediate station, a reciprocable stapler 16 inserts a staple through the packet. At the delivery station C, a pressure member 49 causes the gripper unit 15 to pivot about the axle of wheels 19, 19<SP>1</SP>, through a break in the rails 12, 12<SP>1</SP>, and the cranks 33 are pivoted by a fixed abutment 51 causing the gripping members 35, 36 to open and release the packet P, which slides down the supporting plate 26 into a magazine 53. A pressure member 56 clamps the packet in position and the magazine is rotated through 90 degrees to deposit the packet on a discharge conveyer 58. The magazine is rotated alternately clockwise and anticlockwise so that the bases of the bags face in opposite directions to facilitate stacking from the conveyer 58. In a modification, the discharge station is located near the top of the conveyer chain, so that the supporting plate 26 is inclined, and a pivoted lever (52) acts on the roller 41, causing the gripping members 35, 36 to open.
