Title: Improved mechanism for transferring articles
IPC: G21C19/10
Filed: 1962-07-19
Abstract: 964, 051. Handling devices for use in nuclear reactors. GENERAL DYNAMICS CORPORATION. July 19, 1962 [Aug. 2, 1961], No. 27097/62. Heading G6C. [Also in Division B8] A transfer device for lifting nuclear fuel elements &c. comprises a grapple having a lower body portion, supported on an upper body portion so as to permit limited transverse movement of the lower body portion, a plurality of grapple hooks movably carried in the lower portion, and grapple hook actuating means on said lower body portion. Referring to Fig. 2, the mechanism includes two basic movements, extension and retraction of telescopic tubes 48 and 60 by means of a motor 44 and suspension cables 46, and rotation of guide tube 40 by means of a worm and wormwheel 52 which causes the entire mechanism to rotate within housing 34. Automatic rotation of the lower portion of the grapple head is provided which will rotate it an equal and opposite amount to the rotation of the guide tube; thus a fuel element may be removed from the core, moved radially within the plenum chamber (Fig. 1), and simultaneously moved to a different angular position (when viewed in plan) without altering the axial orientation of the fuel element. A further compensatory motion is automatically provided which raises and lowers the telescopic tubes to enable a fuel element to be moved radially in a horizontal plane. Provision is also made for rotating the lower half of the grapple head in order to unscrew control rod guide tubes and to assist the withdrawal of fuel elements which have bowed. The grapple head (Fig. 3) has co-axial input shafts for rotating the lower half thereof, and for operating the grapple hooks. A force sensing device 158 provides signals of the compressive force during grapple ebgagement and of the tensile force resulting from the fuel rod weight and any binding forces preventing withdrawal. The grapple hook housing 160 is biased away from its supporting plate 162 by spring 164; upward movement of the body 160 caused by its abutment with adjacent fuel,elements closes a micro switch 168 to signal engagement of the grapple hooks. Limited tilting and transverse movement of the grapple hook housing 160 is provided by its mounting 170. Transverse movement is biassed towards realignment by springs 180, and axially movement by springs 186 acting on a cylindrical extension 188 of the grapple hook housing. The gas cooled reactor (Fig. 1) is mounted in a concrete cavity, and has fuel rod handling and charging facilities arranged above the reactor, whilst the control rods are driven in and out of the core from below the reactor. Actual removal and replacement of control rods and control rod guide tubes is achieved from above the core by the transfer device. Storage racks 28 are provided for used and replacement fuel rods &c. Concentric coolant parts 18, 20 are provided, the inner one being the discharge part.

Title: Improvements in or relating to apparatus for winding tape on cables
IPC: H01B13/08
Filed: 1946-09-20
Abstract: 648,249. Covering cores by winding. JOHNSON & PHILLIPS, Ltd., and HAYWARD, A. T. Sept. 20, 1946, No. 28234. [Class 109] In apparatus for winding tape t, usually of paper, on an electric cable 1 of the kind in which the cable is fed longitudinally and at the same time a roll d (or each of a number of rolls) of the tape is moved in a circular path round and round the cable so that the tape winds helically on the cable and is paid off the roll. means are provided for producing a tension in the tape by applying a friction drag acting against the circumferential periphery of the roll. Preferably the drag is generated by the tension of the tape itself. The peripheral drag may be combined with the usual friction drag applied at the sides of the roll, the former drag diminishing and the latter drag increasing as the diameter of the roll decreases so that a more nearly constant drag and therefore tape tension is attained. In the form shown, a pivoted lever 13 moving in the plane of the roll-disc d carries at one end a friction pad 15 bearing against the periphery of the disc and at the other end a pin 16 over which the tape t passes in proceeding from the disc d to a guiding eyelet 6. The angle through which the tape is deflected in passing over the pin 16 progressively diminishes as the diameter of the disc d diminishes so that the applied pressure at the pin diminishes with consequent diminishing drag at the periphery of the disc. Each of the roll-discs d, of which eight, for example, may be carried by a head 7 in planes radial to the axis of the cable, is mounted on a pin 3 between spider-like plates 5, one of which is pressed towards the other through a spring and an adjustable nut 12 to provide the usual friction drag at the sides of the roll.

Patent GB-1072697-A (GB)
Title: Recovery of epoxy-alcohols
IPC: C07D301/32
Filed: 1964-07-10
Abstract: Epoxy alcohols are recovered from the crude oxidate obtained by oxidizing mono-olefins by treating the oxidate with alkali to remove any acids and subsequently distilling the treated oxidate to isolate the epoxy alcohols.  The oxidate is defined as that obtained by (1) liquid phase oxidation of monoolefins with molecular oxygen in the presence of catalysts selected from metals of Groups IVA, VA or VIA, or their compounds, but excluding Cr, or by (2) liquid phase autoxidation of mono-olefins in a first stage, followed by re-arrangement of the hydroperoxides so formed in a second stage by treatment with the catalysts used in method (1). The acid-removal treatment may be effected between the autoxidation and re-arrangement stages in method (2).  Both methods give rise to small amounts of carboxylic acid and percarboxylic acids in the oxidate. The alkali may be solid or in aqueous solution, e.g. NaOH, Na2CO3 or Ca(OH)2 and is generally used in amounts of 0.5-10 times the stoichiometric amount required to neutralize the acids. An example relates to the recovery of 3,4-epoxy-4-methylpentanol-2 and 3,4-epoxy-2-methyl-pentanol-2.
