Abstract: 1,196,839. Arc welding systems. NUKEM NUKLEAR-CHEMIE UND-METALLURGIE G.m.b.H. 12 Sept., 1968 [14 Sept., 1967], No. 43323/68. Heading H2H. [Also in Divisions H3-H5] In a process for contactless striking in t.i.g. welding with high frequency superposition, the open circuit voltage of the welding circuit is increased for a period of less than 10 milliseconds during striking, preferably to around three times the operating voltages, in order to improve the reliability of striking. The output voltage of a welding rectifier S is fed through a separate striking unit ZE and a choke Dr of the sealed welding chamber K, the striking unit simultaneously switching on the high frequency source HF. The additional voltage is generated by way of a transformer T and rectifier arrangement G and is connected briefly by a relay R. If the voltage drop across a resistance W in parallel with relay R exceeds a certain adjustable value, the arrangement is automatically switched over to normal operation in which contact c1 is open and a contact c2 is closed. Two welders may be connected in series. The welding process is used in the manufacture of nuclear fuel elements, a pure helium atmosphere being used for shielding the tungsten electrode.

Title: Blade for use with a centrifugal blasting wheel
IPC: B24C5/06
Filed: 1972-11-27
Abstract: 1404479 Blasting WHEELABRATORFRYE Inc 27 Nov 1972 [5 April 1972] 43731/74 Divided out of 1404478 Heading B3D A blade for use with a centrifugal blasting wheel comprises first and second ends 38, 40 a front surface 36 constituting a throwing surface extending between the ends, a rear surface, and a pair of side rails 44 one extending along each side of the throwing surface and rearwardly thereof, a first portion 48 of each side rail extending further rearwardly of the throwing surface than a second portion 50. The wheel consists of a pair of side plates 12, 14 connected together by spacers 16 riveted to the plates, sleeves 20 on the spacers holding the plates in spaced relationship. Plate 14 is secured to a hub 22 mounted on a bush 24 keyed to the driving shaft 26 of a motor 6 or pulley. The blades 3 are mounted with their side rails 44 in opposed grooves 53 in the plates. The side wall 12 has a central opening 56 and an impellor 54 is secured by a bolt 61 to a centreing plate 58 and the shaft 26. A control cage 64 has a discharge post 66 and is held in an opening in a side wall 70 of a housing 4 for the wheel, the housing having an opening for the propelled blast material. A feed spout 10 supplies blast material to the impellor and is releasably secured to the housing by a screw 80 on a clamp 74. The diameter of the central opening 56 is greater than the length of the blades so that when the clamp 74 is released and the bolt 61 undone, the spout 10, impellor 54, control cage and centreing plate 58 can be removed so that, during assembly, the blades can be passed through the central opening and the blades engaged with the grooves, the blades being moved radially outwards until a curved surface 46 joining the first and second portions 48, 50 of the side walls engages the sleeves 20 of the spacers 16 to prevent further outward movement. On reassembly, the centreing plate 58 prevents radially inward movement of the blades. During removal of the blades, a cover 84 and wear plate 86 may be removed from the housing to permit a force to be applied to the outer ends of the blades. The throwing surfaces of the blades may be flat or curved. The spacers 16 and sleeves 20 may be made as unitary elements.

Title: Improvements in and relating to a method and a device for ingot mould casting of steels and other ferrous products
IPC: B22D18/06
Filed: 1959-12-29
Abstract: 866,663. Casting processes. DAUSSAN, H. J. Dec. 29, 1959 [Dec. 31, 1958], No. 44073/59. Class 83 (1). In a casting method the poured stream is kept out of contact with the atmospheric air while providing a separate degassing circuit for the paired stream so that it does not re-entrain the gases from the cast metal, the upper level of the cast metal is protected from the atmosphere, and at the end of the casting step, the top surface of the metal is cooled from the periphery to the centre. The metal is poured through the inner tube of a pair of tubes 1, 2, forming between them chimneys b for the gases evolved from the cast metal. A fireproof float 4 surrounds the outer tube 2 and rises on the surface of the melt, while a destructible pad 5 damps the pouring jet at the commencement of pouring. In its final position when pouring ceases, an annular cavity 25 in the float receives an evaporation-cooling agent such as water or CO 2  to cause the desired cooling of the top surface. The tubes are so constructed that the inner tube is destroyed above the surface of the melt, while the outer tube is immersed in the melt before destruction so as to provide a seal. Specification 842,687 is referred to.

Title: Improvements in and relating to checking of sheet material for optically detectable iregularities
IPC: G01N21/89
Filed: 1960-12-22
Abstract: 961,727. Flaw detection in sheet materials. FELDMUHLE A. G. Dec. 22,1960 [Dec. 22, 1959], No. 44181/60. Addition to 921, 362. Heading G1A. The parent Specification discloses apparatus for the inspection of sheet material, e.g. paper, for blemishes. The sheet is passed through an inspection area and a spot of light is scanned across it. A photo-cell receives reflected light and feeds a limiter stage which gives an output only if there is present on the sheet a blemish of sufficient magnitude to warrant a fault-indicating signal to be given. The present invention discloses a modification of the above apparatus. There is now provided a section of material known to be flawless, and so mounted that the spot of light scans across both the comparison sheet and the sheet under test. It is arranged that the photo-cell output during scan of the comparison sheet clamps the limiter to a level such that faulty sheets are indicated. The limiter is, in effect, standardized before each scan of the test sheet. A light source projects a beam of light on to a revolving mirror drum 11, Fig. 2, so that a spot of light scans from left to right across both the comparison sheet 13 and the test sheet 10. The light beam passes through a sheet of glass 14 during its scan from e to b, and photo-cells 15, 16 are so mounted that they receive light reflected from the glass as indicated, but not light reflected from the test sheet 10. Photomultipliers 17, 18 receive light reflected from the sheet 10 but preferably receive no light by direct reflection. In operation as the light beam scans from e to b photo-cell 15 gives a pulse which is passed to a monostable multivibrator 35, Fig. 5, which produces a square pulse of duration equal to the time taken for the light spot to scan from e to f. This pulse triggers feeds balancing unit 36 whose output gates clamp 34. Clamp 34 causes the potential imparted to the input of the limiter stage 31 to be at a level preset by potentiometer 37. This potential is superimposed on the output of the photo-electric device during the scan of the material to be checked. It is necessary that the limiter 31 be operative only during scan of the test sheet, i. e. from a to b. To this end, a blanking pulse generator 38, e.g. a monostable multivibrator, produces a pulse which starts as photo-cell 16 is energized and finishes when the light beam reaches position a. The pulse which triggers unit 38 to end the blanking pulse is derived from the delayed output of unit 35. The output from the photomultipliers 17, 18 is passed to the limiter 31 via an amplifier 30, the limiter giving a pulse when a fault is present, which pulse operates a relay 33. In a further embodiment, Fig. 6 (not shown) the limiter output is fed to an integrating circuit so that an indication of the number of flaws is derived.

Abstract: 1,190,638. Making composite plates; welding by fusion. RICHARD THOMAS & BALDWINS Ltd., and INTERNATIONAL COMBUSTION (HOLDINGS) Ltd. 11 Dec., 1968 [28 Sept., 1967], No. 44290/67. Headings B3A and B3R. In producing a corrosion-resistant stainless steel clad mild steel sheet or strip, for large containers or refrigerator body linings, one or more surfaces of a cleaned (e.g. ground or grit blasted) and flat (e.g. milled or ground) billet, slab or plate of mild steel of 0À1% max. carbon is overlaid, by deposition by fusion welding, with austenitic or ferritic stainless steel of 0À08% max. carbon, the fusion welding being so effected and controlled that the dilution, by the mild steel, of the deposited stainless steel (or the first layer thereof if deposited in several layers) does not exceed 15%, and preferably 10%; after removal of welding flux and, e.g. by grinding, surface protuberances, the overlaid billet is soaked and hot-rolled (the temperature not falling below 900‹ C.) to composite sheet or strip; and the latter is descaled, e.g. by pickling, cold-rolled to desired thickness and then annealed at, say, 1080‹ C. for 1 to 10 minutes. Anti-scale paint may be applied before annealing. The rolling and annealing conditions are those appropriate to the stainless steel. The low carbon content of the stainless and mild steels and the stainless steel dilution limit prevents the carbon content of interface martensite from exceeding 0À15% and, hence, the bond from disrupting during working. The dilution limit also guards against the possibility of composition change in the stainless steel extending to its surface after rolling. The extent of the dilution is dependent upon control of welding voltage and speed. The welding may be carried out by M.I.G., T.I.G., manual arc, hot-wire plasma, or wire- or, as preferred, strip-electrode submerged-arc process. Successive weld beads are applied sideby-side over the base length. The weld bead should be flat-topped and 45-degree edged, and re-entrant edges allowing slag trapping and excessive bead overlap should be avoided. To achieve cladding of a given specification, the stainless steel being deposited (at least in the first layer where several layers applied) should be richer in alloy elements, e.g. chromium, and/or chromium may be added to the flux. In an example, by using an austenitic stainless steel containing 22% Cr, 11% Ni, 0À04% C, with a flux containing 1À5% Cr, the cladding produced contained 19À5% Cr, 10À25% Ni. Other stainless steel claddings include those containing Mo and those stabilized by Nb. The Specification includes examples of arc voltage, current, strip electrode size, welding speed, layer and slab thickness, and soaking and rolling and annealing temperatures.
