Title: Improvements in or relating to the manufacture of hydrogen sulphide
IPC: C01B17/16
Filed: 1922-10-03
Abstract: 209,171. Jackson, W. J. Mellersh-, (Koppers Co.). Oct. 3, 1922. Sulphuretted hydrogen.-Ammonia free gases containing sulphuretted hydrogen are passed into contact with an alkali-metal sulphide solution and concentrated sulphuretted hydrogen is obtained on regenerating the scrubbing solution by heating or by passing air or other gas. Preferably gases containing little carbon dioxide such as those obtained in the distillation and cracking of petroleum are employed, but other gases may be used if they are subjected to a preliminary treatment for the removal of ammonia and the reduction of their carbon dioxide content. In the apparatus shown in the Figure gases containing sulphuretted hydrogen are scrubbed with a solution of sodium sulphide in a tower E, and the absorbed sulphuretted hydrogen is conveyed through tank A, pump I and the preheaters J, L to a heater N where the absorption solution is regenerated. Concentrated sulphuretted hydrogen escapes through a pipe U, and the regenerated sodium sulphide solution after passing through a cooler Q, enters a tank B and is returned to the scrubber. The evolution of sulphuretted hydrogen is facilitated by reducing the pressure. Specification 170,572, [Class 55 (ii), Gas manufacture &c.], is referred to.
Patent GB-800911-A (GB)
Title: Improved process for the production of steel
IPC: C21C5/32
Filed: 1954-09-15
Abstract: A process for the manufacture of steel by surface blowing with oxygen comprises directing a stream of oxygen against the surface of the metal, with or without the addition of up to 25 kilograms per ton of metal charged so that the conversion is carried out by oxygen alone without intermediate and concomitant action of slag. The oxygen pressure is preferably insufficient to agitate the surface of the metal, and the stream of oxygen may be directed vertically downwards. In the manufacture of low carbon steels the oxygen blast may be prolonged for some seconds after the completion of decarburization.
Patent GB-532991-A (GB)
Title: Improvements in and relating to electric current measuring instruments
IPC: G01R15/18
Filed: 1939-09-29
Abstract: 532,991. Current meters. AKT.-GES. BROWN, BOVERI & CIE. Sept. 29, 1939, No. 26898. Convention date, March 30. [Class 37] Direct current or undulatory or low frequency alternating current is measured by means of a compensation current which opposes the magnetization produced in an iron core by the current to be measured and is automatically balanced by means of an armature in an air gap in the iron core which controls one or more resistances in a bridge supplied with direct current. The conductor G carrying the current to be measured magnetizes an iron core E having an air gap L. Between the poles P1, P2 of the core is arranged an armature having a D.C. polarizing winding Q. By means of a lever H and spring F the armature varies oppositely two carbon pile resistances W1, W2 which form two arms of a bridge, the other two arms of which are formed by two fixed resistances W3, W4. One diagonal of the bridge is connected to a battery B and the other is connected to a compensating winding C in series with an ammeter A. The compensating winding C is wound on a bridge T which forms a closing piece for the magnetic field produced by the conductor G and acts as a shunt, thus reducing the ampere turns required for compensation. When no current flows in the conductor G the bridge is arranged to be balanced and consequently no current flows in the winding C. When a current flows in the conductor G a torque is produced in the armature, the direction of which corresponds to the direction of the current. One of the resistances W1, W2 is thereby increased and the other reduced, unbalancing the bridge and causing a current to flow in the winding C in a direction to oppose the magnetic field produced by the conductor G. The reading on the ammeter A is then a measure of the current in the conductor G. Alternatively the armature may vary one resistance only, or the two opposite resistances W1, W4, or all four resistances. The variable resistances may be of other forms, such as those with rolling contacts, or Tirill regulators. Hysteresis effects with carbon pile resistances may be avoided by applying periodic pressure variations, for example by means of an auxiliary winding on the core E connected to an A.C. source. Alternatively the exciting coil Q may be supplied with an undulatory current, the A.C. part of which produces the required pressure variations. The battery B may be replaced by a rectifier connected to an A.C. source.

Abstract: 470,949. Photographic printing-apparatus. KEEN & CO., Ltd., A. P., KEEN, A. P., and WILSON, J. H. Oct. 9, 1936, No. 27394. [Classes 98 (i) and 98 (ii)] In apparatus in which a negative is printed simultaneously with the operation of. determining the density of the next succeeding negative, the printing and testing lamps are contained in separate adjacent chambers having openings across which the film of negatives is drawn; the openings occupy a common plane and are so spaced that when one negative occupies the printing position the next negative occupies the testing position. As shown in Fig. 2, the printing lamp 10 and testing lamp 11 are contained in compartments 4, 5, of a chamber 3 having glazed opening 13, 14 across which the film is drawn. Each compartment also contains a non-actinic inspection lamp 12. The film is held against the openings 13, 14 by fingers 17, 17a, Fig. 1, and a platen 15, carried on a rotatable shaft 20 may be pressed on to the negative to be printed by a treadle 22, such action also bringing a photo-electric cell 16, also carried on the shaft 20, into position opposite the testing opening 14. Operation of the treadle also switches on the printing and testing lamps for a predetermined time by means of the switch shown in Fig. 4. The shaft 20 bears an arm 26 which, on depression of the treadle rotates a bell-crank 27 having a gear 28 in constant mesh with a gear 30 on a shaft 31 which also carries a cam 25 engaging the pivoted arm 24a of a switch 24 connected to the lamp circuit. Rotation of the crank 27 brings the gear 28 into engagement with a constantly rotating gear 32 . which thus rotates the cam 25 to switch on the lamps for a period depending on the shape of the cam, the lamps 12 being simultaneously extinguished. Simultaneously with the printing operation, the reading of the photo-electric cell opposite the next negative is taken, and, after printing one negative, the intensity of the printing lamp is adjusted accordingly by means of a hand-controlled rheostat, a variable choke being provided to vary the intensity according to the dimensions of the negative. The film is then drawn across the openings by hand so that the tested negative now occupies the printing opening 13, and the operation is repeated. Specification 376,669 is referred to.
