Title: Improvements in or relating to chromatography
IPC: G01N30/38
Filed: 1964-11-11
Abstract: A gas chromatograph comprises a homogeneous block (13) having recesses in which are formed and / or mounted a calibrated volume (Conduit 27), a detector (one sensor of which is mounted in recess 33), and, partially, means for introducing a sample together with either or both a column interchanging means and a back flushing means, passages within the block bringing said components into operative association. As shown in Fig. 1, to which the above numerals refer, the block 13 is cylindrical in form and two coiled columns 7, 8 are situated around it in furnace 3. The latter is heated by suitable means (not shown) in insulation 2 and the furnace assembly is contained in casing 1. The block contains various recesses in the end faces, those on the right hand side being capable of being suitably connected by rotation of a ring 41 with cut-out portions having an impervious plate 4 to enable the columns to communicate via peripheral openings such as 38, 41 with a flow restrictor which can be connected in series with column 8 alternatively to column 9. A device 5, 6 linked to plate 4 rotates the ring 41. A similar arrangement at the other end of the cylinder permits introduction and withdrawal of carrier, sample and wash gases. An end view of this end of the block is illustrated in Fig. 3 (not shown) and a ring 101 similar to ring 41 makes suitable connections, through ports in the block for admission and withdrawal of said gases. A device 9, 11, 12 is linked to plate 10 to rotate the latter.

Patent ES-318845-A1 (ES)
Title: Boundary follower using oscillating photocells
IPC: G06K11/02
Filed: 1965-10-23
Abstract: Apparatus that will follow the boundary between areas of a record which absorb light differently comprises two light sensitive devices mounted a fixed distance apart, means causing relative oscillation between the devices and an image of the boundary, means for combining the outputs of the devices and means responsive to the combined output to steer the apparatus to follow the boundary. As described the cells oscillate in the direction of the line joining them so that they cross the boundary. Their outputs are fed to a difference amplifier to give a sinusoidal signal at twice the scanning frequency when the centre of scan coincides with the boundary. When there is not coincidence a signal at the scanning frequency appears having a phase indicative of the sense of displacement. This signal causes energization of a steering motor. The cells may be mounted on a Piezo-electric crystal as described in Specification 1, 014, 975. The apparatus may be converted to a conventional line follower by disconnecting one of the cells and offsetting the centre of scan either optically or by applying a bias to the Piezo-electric crystal. A mirror directing light on to the cells may be oscillated instead of the cells themselves and an electromagnetic system may replace the Piezoelectric system.
Patent ES-320423-A1 (ES)
Title: Process for the purification of industrial solutions of hafnium and zirconium salt
Inventor: DE CALMES ALAIN
IPC: C01G27/00
Filed: 1965-12-06
Abstract: Phosphorus and titanium-containing solutions of hafnium and/or zirconium nitrate, are purified by (a) eliminating a major part of the phosphorus as phosphates of Hf and/or Zr, e.g. by decanting the precipitate which forms on settling (b) diluting the solution to 1.5N (c) passing the solution through a cation exchange resin, to fix the Hf and/or Zr and the traces of phosphate and Ti (d) eluting with 1.5 nitric acid to eliminate Ti (e) eluting Hf and/or Zr with 1.5-3N sulphuric acid (f) allowing the resulting solution to stand, and decanting to eliminate last traces of phosphorus as phosphates. In step (a), the P2O5: Hf and/or Zr oxide ratio is preferably reduced to 0.2-0.3%. The cation exchange resin may be an aromatic hydrocarbon polymer containing sulphonic groups. In an example, the sulphuric elution solution was treated with gaseous ammonia to precipitate the oxides of Hf and Zr which were filtered, washed and calcined at 900 DEG C.
Patent ES-361073-A1 (ES)
Title: Telescopic shock absorbers
IPC: F16F9/06
Filed: 1968-12-04
Abstract: In a shock absorber of the kind (Fig. 1, not shown) in which a piston has valved or unvalved throttling apertures in it or a flow path round it and the cylinder in which the piston works communicates with a compensating chamber, the valve has the form shown in Fig. 3. Flow of liquid from the cylinder space beneath the partition 8 into the liquid space 6 of the gas-plus-liquid compensating chamber situated above it will deflect the flexible shim 12 until it engages at t a stop 14. Such deflection is relatively easily brought about, e.g. on high frequency reciprocation of the piston (not shown) of the shock absorber. If, under larger forces, the shim is further deflected it tends to wrap itself around the stop, as shown in broken lines. The valve is thus " soft " for small deflections but " hard " for large ones. In Fig. 4 (not shown) the shim 12 is not clamped under the stop but loosely surrounds its short stem 15. In this form the small-force deflection of the shim is one of translation and only the largeforce deflection is one of flexure. If the shock absorber has a valved piston, the piston valve(s) may also be of the above-described form.

Title: Electrical discharge machining pulse duration control apparatus and method
IPC: B23H1/02
Filed: 1969-03-27
Abstract: An electrical discharge machining apparatus, of the type including an electrode servo feed system to maintain optimum working-gap spacing and having a power supply furnishing working pulses to the gap, is provided with a control circuit which reduces the power content of the working pulses in response to the effect on gap discharge of abnormally high resistance and of abnormally low resistance across the gap. As shown, power pulses are supplied to the working gap of an E.D.M. machine, the gap being defined by an electrode 130 and a workpiece 128 and the pulses being derived from a D.C. source 132 by way of a switching transistor 110 controlled by a multi-vibrator. A circuit including transistors 312, 314 is connected across the gap to detect abnormal conditions, and produces at point P a signal which is applied to the multi-vibrator in a sense to narrow the power pulses applied to the gap, the on-time and off-time of the pulses being varied selectively so that the electrode and workpiece are protected against possible damage due to short-circuits &c. A suitable multi-vibrator circuit is described with reference to Fig. 1 (not shown), and a further embodiment which also alters both the on-time and the off-time of the pulses is described with reference to Fig. 2 (not shown).

Patent ES-409566-A1 (ES)
Title: Milling tool assembly
IPC: B23C5/08
Filed: 1972-12-13
Abstract: Reversible perforated cutter plates, bits or inserts are mounted in notches around the periphery of a rotary tool body by means of threaded gripping members adapted to clamp the cutter flat against the seating surface and tight against edge positioning surfaces when the clamping member is screwed into the tool body. The tapped bore into which the clamping member is screwed is inclined at an angle in the direction of the axis of the perforation of the cutter plate when the latter is seated on the seating surface, the angle being chosen to provide components of gripping force holding the cutter plate against the seating and positioning surfaces. The engagement of the gripping surface of the clamping member with the wall of the cutter plate hole is such that only a fraction of a turn of the clamping member is sufficient to tighten or release the cutter.
