Title: Production of steel pipes
IPC: C21D8/10
Filed: 1975-01-31
Abstract: 1496577 Making pipes; straightening NIPPON STEEL CORP 31 Jan 1975 [4 Feb 1974] 4283/75 Headings B3A and B3E [Also in Division C7] A steel pipe is shaped and its toughness and tensile strength improved by subjecting the pipe to descaling (which improves the uniformity of the subsequent cooling), to heat treatment comprising heating the pipe locally from one end to the other followed by forced cooling, and finally the pipe is expanded in diameter. In an embodiment, a pipe of diameter 762 mm. and length 12 m. is descaled preferably by shot blasting, but alternatively by sand blasting, acid pickling, or mechanical brushing, to an extent of at least 90% on the outer surface. The inner surface need not be descaled if the subsequent forced cooling is effected only from the outer surface. The pipe then passes through two induction heating coils, heating the pipe rapidly locally to a temperature range of 850 C. (above the Ar 3  temperature) to 1000 C. (below the coarsening temperature of austenite grains) preferably at a heating rate of at least 100 C./min. The pipe then passes through a cooling ring which sprays jets of water or water and vapour on to the pipe surface. The ring may be displaced from a position concentric with the pipe so as to correct departure of the pipe from straightness. Cooling may be carried out at a rate of at least 2000 Kcal/C.m.<SP>2</SP> hr., and at an average of more than 10 C./sec. from 800 C. to 500 C. The pipe may then be tempered by heating to 450 to 750 C. (not higher than Ar 1 ), at rate of 100 C./min or faster if the temperature exceeds 600 C. The pipe is then expanded permanently by 0À1% to 0À8%, preferably 0À3% to 0À5% of its diameter.

Title: Improvements in and relating to the manufacture of metal nitrates
IPC: C01G1/08
Filed: 1947-02-21
Abstract: <PICT:0634579/III/1> For the production of metal nitrates by reacting nitric acid with a metal giving rise to the evolution of higher oxides of nitrogen, the acid is brought into contact with that portion of a column of the metal, partly immersed in a heated solution of the nitrate in an atmosphere of oxygen gas, which lies adjacent the surface of the liquid, the nitrate solution formed thereat, together with any unutilized acid being displaced downwardly over the surface of the column by the later entering acid whereby the unutilized acid forms additional nitrate.  As shown, nitric acid and oxygen are supplied through pipes 10, 11 to the interior of a stainless steel reaction vessel 2 containing bars 4 of, say, silver supported on a meshed disc 3 and partially immersed in silver nitrate solution 4a.  The tower is formed with a charging opening 8a and is adapted to be heated to 80 DEG  C. at the beginning of an operation by a jacket 7.  The silver nitrate formed escapes through pipe 12a, and traces of unreacted nitric acid present are removed by passing the solution through granulated silver 15 on a bed of inert material 14 in tower 13.  Oxygen is supplied through pipe 20, escaping into the main reaction vessel 2 via pipe 22.  A heating jacket 21 for tower 13 is provided.  Silver nitrate solution is withdrawn through outlet 34.  Nitrogen oxide fumes from vessel 2 pass to an absorption tower 23 partly filled with quartz &c. 28 and to which water is admitted from pipe 29.  A cooling jacket 39 is provided. Nitric acid solution, withdrawn at 34, may be mixed with concentrated acid for use in vessel 2.  The supply of oxygen to reaction vessel 2 is regulated so that only an occasional bubble escapes through manometer 37.  Specification 634,578 is referred to in connection with the recovery of the nitrogen oxide fumes.

CHADWICK, F., 35, Highgate Terrace, Fulwood, PRESTON TYRE - FABRIC MANUFACTURING CO., Ltd., and COWPERTHWAITE, W., Croft Street Mill, Croft Street, both in Preston, Lancashire. Feb. 16, 1934, No. 5139. [Classes 12 (ii) and 12 (iii)] [See also Group IX] Travellers running upon rings are lubricated by forming or providing metal parts in the ring, such parts being in such close juxtaposition that they will receive by capillary action and transfer to the inner face of the ring, also by capillary action, a continuous supply of lubricant. A ring rail 6, carries rings 7 upon which revolve travellers 8 of strong wire part of which engages the inner face of the ring. The ring plate forms a chamber 9 for lubricant which is fed by a twisted wire 12 to an orifice 11 communicating with a groove 10 of capillary dimension. The stem of the traveller 8 may be clear of groove 10 or may have positive rubbing contact with an edge thereof, the heat generated in the machine serving to liquefy the lubricant which consequently sheds down the ring 7 and around the lower edge thereof. In modifications the groove 10 is comparatively wide and is packed to produce capillary passages by (1) a plain wire, (2) twisted flex (3) a number of light annular metal plates and (4) a number of thin plates of corrugated form. Other filling materials for the groove may be a flat twisted wire, a strip or strips of metal gauze or braided wire. Flow of lubricant ceases on the viscosity increasing due to cooling.

Nos. 5274/49, 16417/49, 23773/49 and 28394/49. Class 20 (iv). Lining boards are secured by fixing to the structure against which they are to be mounted a number of parallel, tubular supports, each of which has an outwardly facing longitudinal slot, the boards being placed against the supports and secured thereto by screws which enter the slots, the opposed free edges of which engage in the screw threads in the manner of a nut. In the form shown, a series of tubes A having open slots B are secured to the building framework and spring clips E are spaced at intervals along each tube. The edges of the lining boards D are placed against the flat portions F<SP>1</SP> of the clips and a cover plate C placed across the joint between the boards. Screws C\ which may be ordinary wood screws, are passed through holes in the plate C and are screwed into the slots B, the boards being tightened on to the spring clips so that they are held resiliently to the supports. Several modifications are described, for example when it is desired to have a continuous lining surface without cover strips, an attachment plate G is first secured to the supports A by screws C<SP>1</SP> and by pronged spring clips E. The boards D are then attached to the plate G by means of pronged brackets H<SP>1</SP>.

Abstract: 1,039,681. Discharge apparatus. G. BAUKNECHT G.m.b.H. ELEKTROTECHNISCHE FABRIKEN. Feb. 8, 1963 [Feb. 9, 1962], No. 5313/63. Heading H1X. [Also in Division H5] Negative oxygen ions for air conditioning are extracted by a D.C. field 7 from a discharge device in which A.C. glow or corona discharges are produced at the edges of thin electrodes 3 of difficultly atomizable metal mounted on one face of an insulating body 1 having one or more laminar counter-electrodes 2 on the opposite face, the electrode(s) 2 and the supply lead thereto being screened by the electrodes 3a and a metal screen 13 connected to the electrodes 3 and maintained at a negative D.C. potential in relation to earth by a resistor 16 of at least 10 ohms. Nitrogen oxides are substantially suppressed and ozone formation either suppressed or controlled. In the arrangement shown the A.C. supplying the electrodes is rectified to provide the D.C. field. The discharge intensity, and consequently the rate of ozone production, is controlled by a potentiometer 8, while the D.C. field, and consequently the rate of negative ion extraction is controlled by a potentiometer 9. The device is surrounded by an additional earthed screen 15. A number of the devices may be suspended from a semiconductive ceiling or false ceiling of a room or stood upon the floor or upon tables or other supports or mounted in the backs of seats and a D.C. source connected between the devices and the ceiling. Alternatively an insulated ceiling electrode may be provided and the D.C. field varied slowly and continuously in a cyclic manner to effect distribution of the ions at head level. In modified arrangements, Figs. 3 and 4 (not shown), the A.C. and D.C. are variable in steps by respective tapped switches 17 and 18. The rate of ion production may be indicated by an electrostatic voltmeter 19 (Fig. 3) or by a glow discharge tube 28 (Fig. 4). The insulating body 1 may be in the form of a tube closed at one end (Fig. 4) or a cylinder, Fig. 5 (not shown). In the latter case metal foil strips 31 for collecting dust may be mounted between the discharge electrodes 3 which are helically wound wires of about 0À1 mm. diameter.
