Title: Improvements in or relating to the production of carbon disulphide and hydrogen sulphide
Filed: 1960-03-05
Abstract: Carbon disulphide and by-product hydrogen sulphide are prepared by reacting a preheated vaporized hydrocarbon feed which is liquid at ambient temperature, which is substantially completely vaporized at a temperature below 200 DEG C., and which consists predominantly of hydrocarbons having at least 5 C atoms in the molecule with sulphur vapour, without premixing of reactants, in a zone substantially completely occupied by a catalyst, said zone being maintained at 700 DEG to 1300 DEG C. as described in the parent Specification, and thereafter continuing the reaction in a non-catalytic zone contiguous with the catalytic zone, the non-catalytic zone also being maintained at 700-1300 DEG C. The hydrocarbon feed may be aliphatic, alicyclic, or aromatic, preferably consisting predominantly of hydrocarbons having at least 6 C atoms/molecule. The reaction may be effected under substantially atmospheric pressure with the temperature in the catalytic zone being 700 DEG to 900 DEG C., and that in the non-catalytic zone being 900 DEG to 1100 DEG C. The reaction may be effected in a silica tube with one end packed with potassium vanadate on silica catalyst. The remainder of the tube being empty and forming the non-catalytic reaction zone. A stoichiometric excess of sulphur may be used, and the hydrocarbon feed may be diluted with an inert gas, e.g. nitrogen. Gases leaving the reaction zone are cooled to condense sulphur which is recycled, further cooled or washed with light oil to isolate carbon disulphide, and washed with aliphatic amine to isolate hydrogen sulphide. Hydrogen sulphide after recovery from the amine may be converted to sulphur by the Claus process, such sulphur being recycled, or may be employed as such, for example, in the manufacture of sodium sulphide. Specifications 798,947 and 939,209 also are referred to.

Title: Method of providing a copper article with a surface layer promoting the adherence of adhesives
IPC: C23C22/63
Filed: 1960-07-14
Abstract: An adhesive comprises 80 parts by weight of copolymer (1:3) of acrylonitrile and butadiene, 100 parts by weight of cresolformaldehyde resin and 15 parts by weight of formic acid the mixture being dissolved in 800 parts by weight of methyl ethyl ketone.ALSO:In order to effect an adhesive bond between a copper body and another article a surface area of said copper body is covered with a layer which is the result of a reaction between the surface of the copper body and an organic nitrogen compound which splits off ammonia at an elevated temperature and is formed by decomposing said compound by heating while in contact with the surface area of the copper body. The term "copper body" includes copper plated bodies and also bodies of alloys containing a substantial proportion of copper. Compounds used for treating the copper are urea, formamide and hexamethylenetetramine to which is added a wetting agent, e.g. triethanolamine or a sulphonic acid salt of an aliphatic hydrocarbon and an oxidizing agent, e.g. 0.5% ammonium persulphate. In an example a copper sheet after moistening with the treatment solution is heated to a temperature of 140-160 DEG C. in a hot air furnace or by contact heating for 5 minutes. The treated surface of the sheet is covered with a layer of adhesive consisting of 80 parts by weight of copolymer of acrylonitrile and butadiene, 100 parts by weight of cresolformaldehyde resin and 15 parts by weight of formic acid by dissolving this mixture in 800 parts by weight of methyl ethyl ketone and spreading it on the sheet. The solvent is evaporated by heating at 130 DEG C. for 30 minutes. The treated sheet is laid on top of a stack of sheets of paper impregnated with a hardenable condensate of the phenolaldehyde type. The stack is transferred to a press and heated to 160 DEG C. under a pressure of 60 atmospheres for 30 minutes to bond the copper to the resin-impregnated paper laminate.

Patent ES-339362-A1 (ES)
Title: Blanking circuits for television receivers
IPC: H04N3/24
Filed: 1967-04-15
Abstract: Pulses derived from the scan generators of a television receiver during retrace intervals and supplied to a video amplifier stage to produce blanking pulses for the tube beam are also utilized to render non-conducting a diode supplying the video signals to the video amplifier stage. With this arrangement the pulses derived from the scan generators may be applied to a point in the receiver circuit which has a lowimpedance to ground, e.g. to the control electrode of a video amplifier stage in a colour television receiver which is driven by a lowimpedance delay line, without the scan generators being designed to supply the power otherwise required or without the need for an additional amplifier stage and without adversely affecting the operation of circuits preceding the point of application. Thus, in Fig. 1, which shows the circuit of a colour television receiver, although the invention is applicable to monochrome (black-white) systems, the video signal derived via diode 20 which detects the negative envelope of the composite video signal, is supplied via a first video amplifier 22 to a delay line 46 (which compensates for the inherent delay in the chrominance circuits) and thence via a diode 86 forwardly biased by source V 3 , to a second video amplifier 26. During retrace intervals a negative pulse derived from the vertical deflection circuit 36 overcomes the forward bias on diode 86 which is thereby rendered non-conducting to isolate the preceding circuitry and the pulse is then effective via video amplifier 26 to produce a positive blanking pulse for the cathode of the picture tube 28. For horizontal retrace blanking a pulse derived from the horizontal deflection circuit 38 is supplied via a pulse amplifier, capacitor and resistor to the junction of resistors 92 and 94 (Fig. 3, not shown).

Patent ES-343251-A1 (ES)
Title: Direct production of solid calcium bromite
IPC: C01B11/20
Filed: 1967-07-20
Abstract: Calcium bromite is prepared by mixing bromine and hydrated lime in an aqueous medium at below 20 C. The rates of addition are controlled so that the pH does not fall below 10, and so that, before the quantity of calcium bromide present reaches 20% by weight and up to the end of the mixing, the proportions of bromine and hydrated lime are kept close to the stoichiometric, that is 1 mole Br 2 to 1 mole Ca(OH) 2 . When the total quantity of reactants has been added the pH is adjusted to between 9À3 and 10À5, and the mixture stirred until the quantity of hypobromite remaining in the mixture represents less than 15% of the total oxidizing power. The solid precipitate containing calcium bromite is then separated from the mother liquor. The weight ratio of Ca(OH) 2 to water of the reaction medium is between 30 and 40% and does not exceed 45%. Alkali metal bromides may be prepared from the calcium bromide obtained in the process by submitting the solid product together with an alkali metal carbonate, sulphate or hydroxide to double decomposition.

Title: Textile creel apparatus
IPC: D01G99/00
Filed: 1968-11-26
Abstract: In apparatus for "creeling" filamentary low or "sliver yarn" which is readily threaded therethrough and maintained free from twisting, tow T supplied from containers or cans 14 passes through guides 34 into the creel, is flattened into strand at 16 and then either spread or condensed to a predetermined width at 18, turned to a path parallel to the axis of the apparatus frame at a turning station 20 and fed from a discharge station D to a processing apparatus such as a Pacific Converter whereby the filaments of the strand are cut or broken into fibres of uniform staple length which are drafted into slivers and coiled in cans in readiness for further processing. At 18 a spreader-condenser bar 36 is rotatable about its longitudinal axis so that tow engaged by an arcuate or curved portion 44 is spread or condensed according to whether it passes over the convex or concave portion. At 16, Figs. 8 and 9, guide bars 56 and 58 straighten and flatten each tow into a generally flat strand and brake it sufficiently to pull out crimps or like deformations. If the tow supply fails or the sliver breaks, the bar 58, pivoted to an electrically insulated bar 60, drops against earthed bar 56 whereby a relay is energised to interrupt the circuit to the driving motor of the converter, which is thus stopped, and when the supply is renewed the motor circuit is restored. If the converter stops, operating lever 84 is automatically and pneumatically moved upwardly thereby rotating bar 60 carrying with it the lever arm 90 which in turn bears down on bar 58 which thus clamps the tow tightly to the bar 56. Air pressure is maintained on pneumatic drag brake assembly 142 so that the rolls thereof will not turn and thus the tow between these rolls and station 16 is maintained taut in readiness for restarting the apparatus.

A number of these segments are spaced along the felt bottom run. The second guide may be a suction box, and is preferably constructed with a plurality of longitudinally closely spaced, transversely extending blades presenting top thin edges to the wire to define the water-permeable surface. The longitudinal shape of the locus of these (blade, edges may define an elongated, non-circular convex curve. The compound web, at the off-running end of a ply-forming segment may pass through a pair of press rolls which may act on the felt carrying the web, or may act on the feltweb-wire sandwich, as shown. In this. latter case, it is preferred to use a plastics forming wire.
Patent ES-366053-A1 (ES)
Title: Delay line arrangement
IPC: H04L25/03
Filed: 1969-04-15
Abstract: A tapped delay line, for use in a transversal equalizer, comprises, for each delay stage, pairs of storage elements, e.g. capacitors 20 and 2011, with isolating circuits between the pairs of stores and between one storage element of one stage and the other storage element of an adjacent stage, with the isolating circuits being rendered conductive alternately to transfer an analogue value along the delay line. As shown in Fig. 2, square waves of opposite polarity PC1 and PC2 are applied to render diodes 21 and 22 conductive while diodes 2111 and 221 &c. in the adjacent stages are non condutive and vice versa. While a positive PC1 pulse renders diode 21 non- conductive a short positive PR1 pulse charges capacitor 20 to its most positive potential then, when the PR1 pulse finishes capacitor 20 discharges to the value held in the previous circuit. When the PC1 signal goes negative diodes 21 and 22 are rendered conductive and the signal is fed, via the voltage follower circuit 23, 24, to the capacitor 2011 of the adjoining stage, after the capacitor has been charged to its most positive potential by a short positive PR2 pulse. In an alternative arrangement the diode gates are replaced by a field effect transsistor (41) Fig. 4 (not shown) connected between the output of the voltage follower circuit and the succeeding capacitor. In this arrangement only opposite phase square waves are required, applied to the fet gates.
