Patent ES-258058-A1 (ES)
Title: Improvements relating to the removal of hydrogen sulphide from hydrocarbons
IPC: C10G27/12
Filed: 1960-05-13
Abstract: Hydrogen sulphide is removed from liquid hydrocarbons, e.g from hydrofined oil, middle distillate oil, or benzole, by contacting the oil with an aqueous alkaline solution of one or more isomeric anthraquinone disulphonic acids the resulting reduced anthraquinone disulphonic acids being subsequently reoxidized with oxygen, or with a gas containing oxygen, e.g. air. The pH of the treating solution is adjusted to more than 7, and preferably to 8.5-9.5 by using ammonia, caustic soda or potash, sodium, potassium or ammonium carbonates or bicarbonates, or alkanolamines as the alkali final adjustment of the pH is effected by means of boric or acetic acid. The treating process may be performed either co-currently with turbulent flow or counter-currently through a scrubber. The reduced treating solution is reoxidized with air either in the upper region of the treating chamber when the treatment is co-current, or in another separate chamber when the treatment is counter-current and then recycled to the treating chamber. The liberated sulphur is removed by filtration either before or after regeneration of the anthraquinone disulphonic acids. According to the Provisional Specification, any organic compound containing a readily reducible carbonyl group, such as Indigo Carmine may be used instead of anthraquinone disulphonic acid.

Patent ES-302206-A1 (ES)
Title: Apparatus for producing yarns of conjugate filaments
IPC: D01D5/32
Filed: 1964-07-17
Abstract: Apparatus for spinning yarns of conjugate filaments having two constituents comprises a spinneret having a single ring of orifices, and two coaxial tubes, the axes being substantially perpendicular to the face of the spinneret, whereby one of the constituents may be fed under pressure through the inner tube and the other constituent may be fed under pressure through an annular space between the two tubes. The internal diameter of the outer tube may be the same as the diameter of the useful internal part of the spinneret. The diameter of the ring of spinneret orifices need not be the same as the diameter of the inner tube, since the pressures exerted on the two constituents to be spun cause them to leave side-by-side through each orifice of the spinneret regardless of the distance between the orifices and the ends of the wall of the inner tube. In one embodiment, Fig. 1 (not shown), one constituent is fed through the interior 6 of tube 1 and the other constituent through the annular space 7 between tubes 1 and 2. The two constituents pass together through orifices 4 in spinneret 3. In a further embodiment, Fig. 2 (not shown), the end of the inner tube, instead of being open is provided with a cap 16 having orifices 17. The proportions of the constituents in each filament may be adjusted by controlling the relative rates of flow of the constituents. The apparatus may be used in the wet, dry, melt or semi-melt spinning of e.g. cellulose xanthate, cellulose esters, or addition or condensation polymers. Two-colour yarns and yarns having a helical crimp may be obtained.

Title: Constant load probe system for coordinate measurement machines
IPC: G01B3/00
Filed: 1975-10-29
Abstract: An arrangement for applying a constant load on the probe of a coordinate measurement machine to eliminate errors caused by operator hand pressure when the probe is manually moved into engagement with a part being measured. In coordinate measurement machines, a carriage movable in the Y axis direction bridges the part being measured. A probe on the carriage is movable in the X axis direction thereby permitting probe movement in any quadrant in X-Y axis directions. To eliminate measurement errors in the Y axis direction, a constant load is applied to the probe by a pair of spring motors mounted on opposite ends of the machine. These spring motors are connected by spring motor cables to the carriage. When the back cable is attached to the carriage, the applied force urges it in the +Y axis direction, and the front cable when attached, urges the probe in the -Y axis direction. To apply a constant load on the probe in the X axis direction, spring motors are mounted on opposite ends of the carriage. Cables from these motors are selectively connected to the probe housing to respectively urge the probe in the +X or - X axis directions. By connecting appropriate spring motor cables to the carriage and probe housing, constant loads are applied to the probe which urges it in the X-Y axis directions in any one of four quadrants.
