Title: Device for scraping a deposit of metal on a cylindrical bar
IPC: F16J9/20
Filed: 1972-04-04
Abstract: 1359085 Cleaning exterior surfaces of tubes COMMISSARIAT A L'ENERGIE ATOMIQUE 4 April 1972 [2 April 1971] 15539/72 Heading F2N [Also in Division G6] A scraper for removing metal deposit from a cylindrical bar movable in a bath of molten metal is of hollow cylindrical form and slidably receives the bar, that part of the scraper nearer the bath being of frusto-conical form terminating in a knife-edged lip which lies against the surface of the bar, the scraper further having slots disposed parallel to its cylindrical axis and extending over the greater part of its length. In the embodiment described, the hollow tube 10 of a manipulator arm for fuel elements in a sodium-cooled nuclear reactor is provided with a scraper 19 for removing the deposit of sodium which forms on the tube 10. The scraper 19 comprises a sleeve 23 formed with a shoulder 20, a frusto-conical lower portion 24 terminating in a lip 25, and a number of longitudinal slots 26 extending over the greater part of the length of the scraper 19 between apertures 27 and the lip 25. Those portions of the scraper 19 between the slots 26 constitute the blades 22 of the scraper and are held against the tube 10 by means of a shoulder 21 on a nut 18 screwed to the lower end of a support piece 6. The support piece 6 is supported in an opening 2 in the reactor vessel 1 between an envelope tube 3 and an inner sleeve 7. The sleeve 7 supports a sealing device comprising a spacer bush 12, four steel sealing segments 13 and gauged spacers 32, the assembly being tightened by a threaded ring 14. A heating collar 28 enables the temperature of the scraper to be regulated, while a shaft guide 29 serves to centre the tube 10. The scraper 19 should be made of a wearresistant material, e.g. steel. In a modification the tightening ring instead of being formed by the shoulder 21 of the nut 18 is provided by an independent ring engaged around the scraper 19.

Title: Improvements in the manufacture of magnetic dust cores
IPC: H01F1/24
Filed: 1934-05-24
Abstract: 438,803. Inductance coils. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Ellis, W. C. ; 17, Devon Street, Malverne, New York, U.S.A.) May 24, 1934, No. 15540. Convention date, May 24, 1933. [Class 37] A magnetic dust core comprises finely divided magnetic particles insulated with colloidal clay, magnesium hydroxide, and sodium silicate. The magnetic material may be made by melting 81 parts of nickel and 19 parts of iron and other magnetic materials in an oxidizing atmosphere, and pouring it into a mould. The alloy thus prepared is rolled hot into thin slabs which are quenched in water, and these slabs are broken and crushed in a hammer or ball mill. The resulting dust is then passed through a 120 mesh sieve and annealed at approximately 885‹ C. in the form of a cake which is again crushed and sifted. The insulation may comprise from 0À1 to 1À3 grams of sodium silicate, 0À1 to 1À1 grams of colloidal clay, and 0À25 to 6À3 grams of an aqueous suspension of magnesium hydroxide, per 100 grams of magnetic dust. A suitable insulation would have 0À77 grams of colloidal clay, 0À64 grams of sodium silicate, and 2À11 grams of an aqueous suspension of magnesium hydroxide per 100 grams of magnetic dust, and is applied by mixing the clay, either dry or in water suspension, with the magnetic dust, adding the magnesium hydroxide suspension and a 50 per cent solution of sodium silicate having a silicate to soda ratio of about 1À6. The mixture is then evaporated to dryness with constant stirring. The insulation may be applied in three stages using one half of the clay, the coated particles being mixed with the remaining clay and compressed at 200,000 lbs. per square inch. The core is then annealed at 500‹ C. for 45 minutes in air, or at 650‹ C. for 60 minutes in hydrogen. Specification 269,510, [Class 37], is referred to.

Multi-vibrator 11 controls a chopper 12 which supplies a square wave of stable amplitude and frequency to the input of a displacement transducer 13. The output from transducer 13 is fed via an impedance converter 14 to a filter 15 which selects the fundamental frequency signal which is applied to a full wave rectifier 16. The rectified voltage is applied to one input of a differential amplifier 17 the output of which is connected to a meter 18. A second chopper 22, synchronized with chopper 12, produces a reference signal which is applied via a second impedance converter 24, filter 25 and rectifier 26 to the other input of differential amplifier 17. The components of the two chains 14, 15, 16 and 24, 25, 26 are matched so that the arrangement provides automatic compensation for any changes of ambient temperature. The chopper circuits 12 and 22 each comprise a transistor gate circuit, and the multi-vibrator 11 is also transistorized. The arrangement is used to measure the torque of a shaft, the transducer 13 rotating with the shaft and having its primary and secondary coils coupled to the measuring circuit by two slip rings or rotatable transformers 31, 32, Fig. 2 (not shown).

[Also in Group XXX] The walls 15, Fig. 2, of the pallet of the parent Specification are prevented from rising through their pin-and-slot connections 16 to the corners 6 of the pallet by a second peg 17 running in the same slot as each peg 16. When the walls are to be removed or folded they are first swung so that the peg 17 leaves an upper aperture in the corner member 6. In the construction illustrated the slots of the pegs 16, 17 are formed by gaps between a metal plate 8, Fig. 3, and an angle member forming the corner member 6. Each wall overlaps the adjacent wall at one end and is overlapped by the adjacent wall at its other end. The walls are secured by catches comprising bow-shaped members 20, 21 Fig. 5, through each of which passes s slide 34 having a semi-cylindrical projection 33 adapted to take in the corresponding recess in the bow 21 in the lock position and in a recess 36 of the bow 20 in the unlocked position.

[Class 145 (i).] The work to be cut is carried past the cutter in an endless jig. In a machine for finishing off pre-formed blanks, the jig 5 has an endless periphery of channelshaped cross-section divided by partitions into boxes 7 which receive the work. The base 9 of the jig has a circular hole 10 which receives an annular flange 11 on a disc 12 ; the latter has a diametral slot 13 receiving a vertical guide 14 of non-circular outline, slidable in a slot 15 in the base of the machine. The jig is thus rotatable about a vertical axis which is displaceable relatively to the cutter 2. The jig is rotated by a pinion 19 which engages a chain rack 17 mounted on the interior of the jig ; the pinion 19 is mounted on a pivoted arm 21 and is biassed by a weight 22 or by a spring to press the flanges 6 of the jig against the outer rings 4 of ball bearings provided above and below the cutter 2. On either side of the cutter 2 spring- pressed jaws 24 engage the work to hold it in the boxes. After the cut, the work is ejected by a pusher 25 normally held inoperative by a spring 26 and actuated by a stationary cam 27 on the disc 12. The contour of the rack 17 may be so chosen relatively to the guiding edges 6 of the jig as to keep the driving pinion 19 and cutter 2 more or less equidistant, or to give a slight wedging action at the commencement of the cut upon each work-piece. The jig may be inverted, the driving pinion 19 then extending upwardly into it. The work-receiving boxes 7 may be formed in the inner periphery of the jig, the driving pinion 19 being outside the jig. The jig may comprise a number of work-receiving boxes permanently connected together to form an endless member.
