Patent ES-260726-A1 (ES)
Title: A heat treatment process for aluminium-based alloys containing magnesium and silicon
IPC: C21D9/00
Filed: 1960-08-31
Abstract: Semiproducts such as sheets, bars, ribbon, tubes or wires in aluminium base alloys containing magnesium and silicon are heat treated by moving them along continuously, e.g. on a single conveyer 4 as shown in Fig. 5, through a first furnace 1 to put magnesium and silicon into solid condition, then through a quenching chamber 2, where cooling is effected by either forced air cooling or by water or mist sprays, and into a second furnace 3, which is heated by forced hot air circulation, e.g. to between 100 and 250 DEG C., to be subjected to a stabilizing treatment which is a short-term age-hardening below the normal age-hardening temperature, the time interval between quenching and reaching stabilizing treatment temperature being less than ten minutes the stabilized semiproducts are then subjected to a final heat-treatment when convenient. Conveniently the first furnace is also heated by forced hot air <PICT:0949188/C3/1> circulation, e.g. to between 450 and 600 DEG C. The surfaces of the semiproduct may be finished after the stabilizing treatment and before the final heat treatment.

Title: Textured multilobal filament yarn
IPC: D02J1/22
Filed: 1961-11-20
Abstract: Twisted or untwisted yarn is crimped and bulked by a combination of hot-stretching and passage between intermeshing toothed wheels so that constituent, continuous thermoplastic filaments having a multilobal cross-section assume sinusoidal deformations the apices of which are located in haphazard relationship with respect to each other at any point along the length of the yarn and the lobes of the filaments are randomly bent to varying extent along the length thereof to distort their normal <PICT:0925732/IV(a)/1> symmetrical disposition. The filaments may be of polyamides, polycarbonates, polyesters, polyolefins including polyethylene and polypropylene, polyurethanes, vinyl and/or acrylic polymers or copolymers, and/or mixtures thereof, particular forms of which are specified. The lobes may be of different length. Yarns of different composition and denier may be doubled before treatment. As shown, a trilobal yarn 10 of incompletely oriented filaments supplied from a wound package 11 on a bobbin 12 (or directly from a spinning machine) passes around a snubbing bar 13 (acting only as a guide) through guide 14 and feed rollers 15, around a heated draw pin 16, whereat alternation of the yarn is concentrated, and several spaced turns between cold or cooled, cylindrical and/or conical crimping wheels 17, 18, and around a fixed spacer bar or rotatable roller 25, and the treated, potentially crimpable yarn is taken up by a ring twisting assembly 27. The crimp &c. is fully developed in the yarn, before or after weaving, knitting or tufting into a fabric or carpet, e.g. by wet or dry heat treatment in relaxed condition.

Abstract: A track-switching system for carriages rolling or sliding on tracks A or B, Fig. 1, each formed by two parallel rails 1 spaced from each other by a continuous slot 2 providing a passage for load-carrying suspension elements (12), Fig. 2 (not shown), carried by the carriages (11), comprises two guide switches of Y-shape connecting the tracks A and B, each switch including a section of arcuate contour and the sections connected one with the other and curved in opposite directions, contra-rotatable wheels 3, 4 supported for rotation about axes coincident one with the centre of one section and one with the centre of the other section and fingers 5 pivoted at 8 to each wheel, against the urge of springs 9, the arrangement being such that an extremity 6 of a finger 5 on one wheel, e.g. 3, moves a carriage along the associated arcuate section of track whilst the extremity 6 of a finger 5 on the wheel 4 moves the carriage along the arcuate track section associated with the wheel 4. The fingers 5 and wheels 3, 4, are constructed and operate in the manner described in the Specification 962,438. The fingers of the two wheels have at least their extremities displaced relative to each other in the direction of the axes of the wheels in such a manner that the extremities cannot strike each other during rotation of the wheels, as described with reference to Fig. 3 (not shown). Alternatively, the extremities are chamfered. The carriages are driven along the tracks A and B by chains. The wheels 3, 4 may differ in diameter. The switching from one track to the other is effected by pivoted shutters 15.

Title: Ammonia purification
IPC: C01C1/02
Filed: 1966-12-27
Abstract: In a process for removing an acid gas contaminant from an impure ammonia vapour stream containing less than 10% by weight each of acid gas and water, the vapour is scrubbed at a constant of 0 DEG to 100 DEG F. temperature and superatmospheric pressure with a concentrated aqueous ammonia solution formed by supplying to and vaporizing in the contactor liquid ammonia at a higher pressure at a rate to maintain the constant low temperature, and water at a rate to maintain in the solution a constant high molecular ratio of ammonia to acid gas of at least 5 to 1 a purified vapour stream is withdrawn containing a small, fixed concentration of acid gas and a small variable amount of water, at a rate to maintain constant the superatmospheric pressure in the contactor and a portion of the ammonia solution is withdrawn separately, containing the acid gas removed from the impure vapour stream. The impure vapour stream may have contained more acid gas than water, and the purified stream more water than acid gas, on a molecular basis. The acid gas may be H2S and be present in the impure vapour as more than 0.1 weight per cent, and as no more than 100 p.p.m. by weight (on a dry NH3 basis) in the purified vapour stream. The withdrawn portion of the ammonia solution may be heated and partially vaporized, returning the ammonia-rich vapours, containing only a minor proportion of the acid gas in the withdrawn portion, to the contactor as part of the initial impure vapour stream, leaving most of the withdrawn acid gas in the unvaporized portion, to which additional water may be added and from which the acid gas may then be stripped at a higher pressure.

Title: Single-wire mechanical wave depth gauge
IPC: G01F23/296
Filed: 1967-07-31
Abstract: In a liquid level gauge the echo time of an acoustic pulse transmitted along wire 7 by transducer 6 and reflected at an impedance discontinuity provided by float 21 is determined on oscilloscope 14. For gauging the level of an inflammable liquid in a tank (Fig. 4), the transducer is mounted in an explosion-proof chamber 37 fixed to the tank and is coupled to the wire by a tapered acoustic waveguide 61 effectively acoustically isolated from the chamber. An acoustic delay line 34, formed by wrapping the wire round a drum surfaced with plastics foam, and a time gate circuit 9 are used to eliminate the disturbing effects of echoes arising from acoustic impedance mis-matches in the coupling between the transducer and the wire.

The oligomer may contain an inhibitor, e.g. poly-2,2,4-trimethyl dihydroquinoline and is applied as a melt or in solution in a hydrocarbon or halogenated hydrocarbon to glass filaments or fabrics. The impregnated material is formed, solvent if any removed, and the oligomer cured at 130-280 C. A peroxide catalyst may be added to reduce curing times or an accelerator, e.g. cobalt naphthenate. In a particular embodiment, laminates are formed from several layers of impregnated glass fibre, if desired with a copper face, and pre-cured at 130-280 C. under a pressure of 1-200 kg./ cm.2 then further cured under a lighter load. In the examples are used oligomers (degree of polymerization about 5) of (a) 1,6-dicyclopentadienylhexane, (b) 1,3 - dicyclopentadienylmethyl - 2,4 - dimethyl benzene and (c) a mixture of (a) and (b). In one example glass filament is passed through a bath of oligomer, wound on a mandrel and cured to form a tube and in other examples layers of impregnated glass fabric are laminated and cured under pressure, in one instance with a copper face. Di-tertiarybutyl-peroxybutane was used as catalyst.
