Title: Improvements relating to the manufacture of hydroxylamine
IPC: C01B21/14
Filed: 1959-01-17
Abstract: Hydroxylamine sulphate solution is prepared by a continuous process in which SO2 is reacted <PICT:0902681/III/1> with an aqueous solution of ammonium hydroxylamine disulphonate containing ammonium nitrite, and ammonium carbonate and/or ammonium bicarbonate, the resulting solution of ammonium hydroxylamine disulphonate being subsequently hydrolyzed by heating, characterized in that the aqueous solution of ammonium hydroxylamine disulphonate containing ammonium nitrite, and ammonium carbonate and/or bicarbonate is circulated in a system, cooled to at least 0 DEG C., SO2 and ammoinum nitrite solutions containing ammonium carbonate and/or bicarbonate being introduced separately into the circulating solution at different places, the solutions and SO2 flowing concurrently with each other, the SO2 being introduced in stoichiometric excess relative to the ammonium hydroxylamine disulphonate formation so that the free SO2 content of the ammonium hydroxylamine disulphonate solution is at least 2g/litre, the proportion by volume of the circulating solution to the amount of aqueous ammonium nitrate solution introduced per unit time being such that the pH of the circulating solution between the inlet of the ammonium nitrite solution and the SO2 inlet is at most 6 and between the SO2 inlet and outlet of the disulphonate solution to be hydrolyzed by heating, the volume of which solution corresponds to the volume of ammonium nitrite solution introduced, the pH falls to within the range 1,5 - 2,5. Ammonium hydroxylamine disulphonate solution containing ammonium nitrite and ammonium carbonate and/or bicarbonate is circulated by pump 4 at -3 to 0 DEG C. through tower 1 packed with filler bodies and through cooler 5. Aqueous ammonium nitrite solution, prepared by reacting nitrous gases with aqueous ammonium carbonate and/or bicarbonate solution and containing 10 - 20% nitrite with an amount of carbonate or bicarbonate in excess of 2,5 - 10% of the theoretically necessary amount calculated on the nitrite produced, is passed through pipe 3 at such a rate that the pH of the circulating solution between 3 and tower 1 is adjusted to between 4 and 6. SO2-containing gases in excess of 2 - 6 grms./litre are introduced at 7 into tower 1 and flow concurrently therein with the solution entering at 6, so that the pH of the solution is between 1,5 and 2,5. Residual SO2-containing gases leave through 8, and ammonium hydroxylamine disulphonate solution is removed at 9 to be hydrolysed by heat to hydroxylamine sulphate in a tower heated by steam to 102 - 104 DEG C. The excess SO2 liberated during hydrolysis may be returned to tower 1. Where gases containing 5 - 15% SO2 and inert gases are used, gases removed at 8 may be returned to tower 1 after addition of SO2. Specification 668,610 is referred to.

Patent ES-304900-A1 (ES)
Title: Machine tool
IPC: B23D3/04
Filed: 1964-10-03
Abstract: A punch-, and die-, cutting machine comprises a tool-holder 21 on an arcuate slide 61 having an axis horizontally disposed above a work support 6, the slide being mounted on a carriage 15 reciprocable along vertical or oblique paths. The work support 6 is rotatable by an electric motor on a compound slide 5, 2. The slide 5 can be fed intermittently in synchronism with the tool 20. The tool-carriage guide 14 is angularly adjustable on a head 13 which can be swung through 180 to bring a second tool-holder 78 into operation. The holder 78 is rotated by a motor 7 through a clutch 75. The motor 7, through an infinitely variable belt-drive 8 and a gear-box 9, also rotates a cam 11 having grooves 19, 23 which respectively reciprocate the carriage 15 and oscillate the tool-holder on its arcuate guide. The groove 19 is engaged by a follower (24) on a lever pivoted on a shaft (25). The lever has a groove 27 to receive an adjustable block (28) pivoted to a sliding block engaging an arm 17 secured to the slide 15, the arm being connected to a counter-balance spring (37). By rotating a handwheel (26) on the shaft (25), the block (28) is adjusted to vary the tool-stroke to adjust the limits of the stroke, the slide 17 is unclamped and adjusted by a shaft 34 and a screw 36. The groove 23 is engaged by a follower 38 on a lever 39 rocking on a pivot 40 and connected by sliding blocks to a lever 43. A pantograph bar 46 connected to the lever 43 moves a roller-slide 55 to pivot a lever 52 around a pivot 53 to raise a block 58 sliding in the end of the lever. The block 58 is pivoted to the tool slide 61 and causes it to move round the arcuate guides 22 on each side of the slide. The lowest position of the holder 60 is determined by stops 64 and 65, the latter of which is engaged by a stop 66 on the holder. These stops take the cutting forces whilst a straight portion of a punch is cut before the cam 23 causes a radiussed cut to be taken at the base of the die profile. The radius of a cut to be made is determined by the setting of the tool 20. To cut the inner surface of a die, a modified tool and holder 69, 70, Fig. 8, are fitted. To flare a die, the tool-carriage guide 14 is set over.

Patent ES-360412-A1 (ES)
Title: Maximum torque reel drive utilizing an inertia compensation and counter emf control
IPC: B65H23/198
Filed: 1968-11-19
Abstract: Constant tension is maintained in wound material by energizing the winder motor with an input signal proportional to the back e.m.f. of the motor and inversely proportional to the linear speed of the material. A signal representing the linear speed of the material is derived from a tachometer 18 and applied to one input of a differential amplier A1, the output of which is fed to a reversible motor 30 driving ganged potentiometers 16, 36, 111. The other input to the amplifier is a signal representing the back e.m.f. of winder motor M but reduced according to the position of slider 24 of the first potentiometer 16. The result of this is that the motorized potentiometers take up a position representing the ratio of back e.m.f. to linear speed which, the Specification establishes, is proportional to the ratio of the diameter of the wound material, D, to the motor field flux, #. The second potentiometer 36 provides a reference signal I, proportional to D/#, to a current regulator 61 which controls the current in the armature of motor M according to the reference signal. A compensating signal IC is also applied to the regulator to alter the armature current during acceleration or deceleration of the mill. The signal IC is provided by a differentiator 60 receiving the linear speed signal from tachometer 18, a function generator 70 employing a motorized potentiometer whose position is determined by the diameter of the wound material, and the third section 111 of the first motorized potentiometer 30. The back e.m.f. signal is derived from the applied armature voltage V corrected for resistance drop IaRa. The field of the motor is normally fully energized but the field is weakened by a regulator 114 at high winding speeds.
