Filed: 1962-06-27
Abstract: Phosphate coatings are formed on ferrous metal surfaces by a process comprising precleansing, coating and after-rinsing wherein during, (i) precleansing, the metal surface is cleaned with an alkaline solution having a minimum pH of 11 and a minimum pointage of 1.5 (for definition see Specification), (ii) coating, the cleaned surface is treated with aqueous acid phosphate solution at 54-79  DEG C. containing not less than 0.07% by weight zinc ion, calcium ion in weight ratio to zinc ion of from 0.5-8.0, phosphate ion associated in conventional amount with the zinc and calcium ions, nitrate ion (calculated as NO3) in weight ratio to phosphate ion (calculated as PO4) of from 0.2 to 5.0 and an oxidizing agent capable of oxidizing ferrous ion to ferric ion in amount equivalent to between 0.01 and 0.2 gms. of nitrite (calculated as NO2) per litre ; and during (iii) after-rinsing, the coated metal is rinsed with a dilute aqueous acidic solution wherein free acid is absent but hexavalent chromium is present in an amount of 0.01-1.0 gms./litre (calculated as CrO3). There is no upper limit for the pH of the cleaning solution and no critical upper limit for the pointage, although a pointage of 75 should not in general be exceeded.  The alkaline cleaning solutions may be composed from alkali metal silicates, carbonates, phosphates or hydroxides or mixtures thereof, and may also incorporate a surface active agent, e.g. ethoxylated alkyl aryl phenols or "Triton" (Registered Trade Mark), ethoxylated alkyl alcohols or "Surfonic" (Registered Trade Mark).  Coatings formed by the process of the invention range in weight only from 150-300 mgs. per sq. foot and the coating temperature may range from 54 to 79  DEG C., preferably 68 to 73  DEG C.  The precleaning is operated at about the same temperature as coating.  The nitrate ion may derive from any soluble nitrate salt provided the metallic cation of the salt is not detrimental, e.g. alkali metal salts such as sodium nitrate.  The nitrite ion may derive from any water-soluble salt provided the metallic cation is not detrimental, e.g. alkali metal nitrites such as sodium nitrite. A preferred range of nitrite concentration is 0.05-0.16 gms. (calculated as NO2) per litre.  Other oxidizing agents may be employed in equivalent amounts, the preferred alternative being per-oxygen compounds i.e. hydrogen, metal and organic peroxides. The pH of the coating solution ranges from 2.4-2.9.  The free acidity (for definition see Specification) is between 0.4 and 1.5 and the ratio of total to free acidity is preferably between 6 and 25.  The pH of the rinsing solution may vary from about 2.4 to 3.5 and may be prepared from soluble alkali metal or alkaline earth metal salts of any oxychromium acid, e.g. lithium, sodium, potassium, calcium, magnesium or ammonium chromates or dichromates or mixtures thereof ; and may also contain a minor amount, 0.0015-0.01 gms./litre, of phosphate ion (calculated as PO4) devoid of any free acidity.

Title: Improvements in or relating to the production of sulphuric acid
Inventor: MOLLER LEOPOLD
IPC: C01B17/76
Filed: 1957-08-13
Abstract: <PICT:0852073/III/1> Gases containing SO2, gaseous organic compounds and moisture, before being dried by contact with strong sulphuric acid (containing 92-98% wt. H2SO4) are first treated with weaker sulphuric acid (containing 70-90% wt. H2SO4) which is maintained at 90-170 DEG C. by external heating to remove the organic compounds, any droplets of weak acid remaining in the gases after removal of the organic compounds therefrom being eliminated by a form of spray separator before the gases are dried.  As shown, SO2 gases saturated with water vapour, enter the weak acid tower 52 through main 78 and pass in countercurrent to a stream of weak acid circulating from tank 53 through line 55, tower 52, and heater 85 e.g. a tubular steam heater.  Residual SO2 freed of part of its moisture and all the organic compounds leaves the tower by conduit 79, passes through spray separator 80 for removal of entrained weak acid droplets, such removed acid being returned to tank 53 by line 81, and enters drying tower 56 where it flows in countercurrent to a stream of strong sulphuric acid circulating from tank 58 through line 60, tower 56 and cooler 57.  SO2 gases freed from residual moisture pass through main 82 to a catalytic converter 83 from which they emerge as SO3 gases which enter the bottom of absorption tower 61.  The gases ascend the tower in countercurrent to a stream of absorber acid (containing above 98 to 99% wt. H2SO4) circulating from tank 63 through line 65, tower 61 and cooler 62.  Absorber acid product and weak acid contaminated with organic compounds leave the plant through lines 71 and 73 respectively.  Water, and strong acid from line 60, are added to the absorber acid by lines 74 and 76 respectively, the quantities added being controlled by valves 75 and 77 so that the total amount of water i.e. water added as such plus water contained in the strong acid, is sufficient to balance that removed from the absorber acid by the SO3 gases, thus maintaining a constant concentration of H2SO4 in the circulating absorber acid.  In order to maintain the concentration of H2SO4 in the weak acid and strong acid circulating in towers 52 and 56 the concentration of which is lowered by the absorption of water from the SO2 gases, controlled proportions of absorber acid are added to tanks 58 and 53 by lines 66 and 68 respectively.

Title: Improvements relating to Agricultural Machinery
Inventor: MOUNTFORD JAMES COTTON MARTIN
IPC: A01F12/44
Filed: 1966-06-08
Abstract: 1,194,533. Combine harvesters. J. C. M. MOUNTFORD. 31 May, 1967 [8 June, 1966], No. 25600/66. Heading A1F. [Also in Division B2] In a combine harvester, a sieving apparatus comprises a circular sieve 1 across which grain to be sieved is moved by means of one or more brushes 2, thus causing the oversize grain to be removed at the periphery or centre of the sieve and the undersize grain to be collected beneath the sieve. The sieve may be flat, dished (Fig. 2) or conical and may consist of a circular plate or disc which may be perforated or in the form of a mesh grid. Movement of the grain towards the periphery or centre of the sieve is governed by the shape of the brush and its direction of rotation relative to the sieve. In Fig. 7, two sieves 1 are mounted one above the other. The grain is fed from a duct 3 on to the upper sieve. The coarse grain is brushed by a rotating brush 2 to the periphery of the sieve into a funnel 12 which feeds it on the lower sieve where the sieving operation is repeated, while the fine grain which has passed through the screen is removed via a funnel 13. In Fig. 8, the feed pipe 3 is connected to an auger 5 which feeds the grain into a chamber 7 where it is met by an upward air current supplied through a pipe 6, which may be a central support for the brushes. The air current removes the lighter constituents of the grain and directs them towards a pipe 8. In Fig. 11, the undersize and oversize grain is collected on flat horizontal members 12<SP>1</SP>, 13<SP>1</SP> and is brushed to centre ducts 4, 4<SP>1</SP> and to an off-take point X at the axis of the apparatus, The sieving apparatus is mounted as at 10, Fig. 10, in gimbal bearings on the combine harvester alongside the driver 11 so that a visual check of its performance may be made.
