Title: Improvements in or relating to apparatus for the detection of faults in elongated magnetisable bodies
IPC: G01N27/90
Filed: 1956-03-12
Abstract: 794,862. Electric coils. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVEL LE SOC. ANON. STIN. March 12, 1956 [March 12, 1955; Dec. 31, 1955], No. 7687/56. Class 35. [Also in Group XXXVI] Apparatus for detecting faults in magnetizable cables and other elongated bodies contains a cylindrical magnetizing unit divisible longitudinally to enable it to be assembled round the test-piece (Fig. 2). Each half of the magnetizing unit (Fig. 1) comprises a ferro-magnetic casing 1 containing half-windings 10 of an air- or iron-cored measuring coil, and half-windings 6 of an excitation coil constructed of resilient, e.g. beryllium bronze, wire, which contact the corresponding half-windings of the other half of the unit in holes in insulating plates 12. Guide tube 7 which locates the test-piece is wholly or partially non-magnetic. In an alternative embodiment (Figs. 5 and 6) the excitation halfwindings 21, 22 comprise semi-annular plates of, e.g., copper, the upper half-windings 21 being pressed by springs 23 to contact lower halfwindings 22 at integral silver contact points 27, half-windings or contact points being offset to provide a helical path for current. Modified spring locations are described. Operation.-D.C. is supplied to the excitation coil to magnetize the cable under test to saturation. Relative axial movement between the magnetizing unit and the cable causes field variations due to flaws in the cable to induce in the measuring coil E.M.F.'s which are amplified and fed, with the output of an integrator to furnish the time integral, to a recording unit, the paper feed of which may be synchronized with said relative axial movement by the mechanical or electrical connection of the paper feeding device with a measuring roller supported on the magnetizing unit.

Abstract: 1302418 Geographical timepiece SYNCHRON SA 18 Feb 1970 [20 Feb 1969] 7696/70 Heading G3T A watch for indicating the time in two geographic. zones by means of an hour hand 19 which is additional to conventional hour and minute hands 20, 21 has two setting positions of its winding and setting stem 6. In an extreme outer position of the stem 6, a clutch wheel 10 is slid inwards by a yoke 8 along a square portion 11 of the stem 6 so that toothing 37 of the clutch wheel 10 engages a setting pinion 29 and a wheel 30 freely set thereon. The pinion 29 is fixed to a gear-ring 31 which drives an intermediate wheel 28 having a pinion 27 and thus a wheel and arbor 26 associated with the additional hand 19. Simultaneously the wheel 30 drives a minute wheel 24 having a pinion (25) and which drive a minute cannon 22 and an hour wheel and arbor 23 respectively. Minute hand 21 and hour hands 20, 19 are thus set together. In an intermediate position of the stem 6, the toothing 37 engages the pinion 29 but not the free wheel 30 because a portion 30b thereof is relieved. The extra hand 19 may thus be set, while the conventional hands 20, 21 are allowed to remain stationary by means of a clutch comprising twelve holes 34 in the hour wheel 23, two studs 35 on the wheel 26, and a spring 33. The three positions of the stem 6 are determined by a rocking lever 7 which acts on the clutch arm 8 and carries a pin (18) Fig. 1 (not shown) engaging one of three notches (15, 16, 17) in a spring arm 14 of a bridge 13. The watch further comprises a date-ring 2 and a seconds hand 39.

Title: Removing ammonia from gases
IPC: B01D53/58
Filed: 1973-02-21
Abstract: 1426564 Removing ammonia from gases SIMON-CARVES Ltd 21 Feb 1973 [7 June 1972] 8527/73 Heading C1A [Also in Division C5] Ammonia is removed from gases, and converted to innocuous products by washing the gas in a saturator with an inorganic acid, and then burning the ammonium salt solution obtain with the addition of a suitable fuel, at a temperature such that nitrogen, water vapour, and the acid or its anhydride occur as combustion products, and at least the acid or its anhydride is recycled to the washing stage after suitable cooling. The gas to be treated, preferably coke oven gas which may be obtained from the collecting main of the ovens, after only moderate cooling and thus still containing its tar constituents, is passed directly, as shown in Fig. 1, via line 11 into spray saturator 10 and leaves via line 12. The inorganic acid, preferably sulphuric, but may be HCl or sulphurous, is atomized through nozzles 13 and 17 and drawn off at the base via line 14. Part is recycled via pump 15 and line 16, and the remainder is passed through line 18 to reactor 19. The feed through line 18 is as concentrated as possible. A fuel, e.g. part of the treated gas, is fed through line 20 together with combustion air through line 21. The resultant combustion products are cooled in heat exchanger 23 to a point slightly above the dew point. The acid content of the vapours is removed in unit 25 and recycled to the scrubbing tower. The residual gas may then be discharged via line 26. The acid may be picked up in unit 25 by means of water, part of which may be introduced from the top of the unit, or a small amount of alkaline solution (Fig. 3, not shown) may be introduced through the top of the column. The small amount of salt solution so formed may be fed into the acid circulation or fed separately into the furnace 19, and the resulting oxides separated, dissolved in water and reused. The combustion products discharged from furnace 19 may be used for raising steam (Fig. 2, not shown) and then passed directly back to the saturator. A catalytic material having as active constituent a metal of Groups V to VIII of the periodic table according to Mendeleev may be introduced into the solution of the ammonium salt, when conditions in the furnace 19 can be adjusted so that there is an oxygen deficiency and reducing conditions obtain and the catalyst is discharged as a fine metallic dust together with some oxide. The metallic dusts pass either directly back to the saturator or to the acid recovery plant where they are dissolved in the scrubbing acid and re-used.
