Title: A method of preparing disubstituted chlorinated benzene derivatives
IPC: C07C17/12
Filed: 1959-06-13
Abstract: Para-chlorinated benzene derivatives, in particular, p-dichlorobenzene and p-chlorotoluene, are prepared by passing gaseous chlorine into-the compound-to-be-chlorinated in the liquid state, the chlorination being carried out in the presence of a chlorination catalyst dissolved or dispersed in the liquid and in the presence of a "para orientation catalyst", such as a mixture of sulphuric acid, a sulphonic acid and a small proportion of water, which is capable of constituting a separate phase. After chlorination the mixture is allowed to separate into two liquid layers, and the appropriate layer is worked up to separate the desired para-chlorinated derivative from the isomers and from higher chlorinated products. Suitable chlorination-catalysts are: antimony sulphide, chloride or chloro-sulphide, and ferric acid. In an example, antimony trichloride and sulphur are dissolved in dry benzene and chlorine is passed into the solution, with stirring, for 45 minutes. A mixture of sulphuric acid, benzene sulphonic acid and water is then added and the stirring and addition of chlorine are continued, while the temperature is maintained at about 20 DEG C. The temperature is then allowed to rise to 50 DEG C. to prevent p-dichlorobenzene from crystallizing out: and the two liquid layers are decanted. The chlorobenzene layer is washed with dilute hydrochloric acid, neutralized, dried and distilled. The product contains over 90% dichlorobenzene in which the para : ortho ratio is 5 to 6.5. The product also contains 5% to 10% of monochlorobenzene, and only 0.2% of higher chlorinated derivatives. Another example relates to the production of ortho- and para-chlorotoluene from toluene. In other examples, toluene sulphonic acid, p-chlorobenzene sulphonic acid, and a mixture of benzene and dodecylbenzene sulphonic acids, are used, together with sulphuric acid and water, as "orientation catalysts".

Title: Restoration of the activity of inorganic sorbents
IPC: B01J20/34
Filed: 1960-09-13
Abstract: Zeolitic absorbents, activated carbons or activated alumina, which have been used in the separation of organic compounds and have become de-activated by the retention of organic contaminants after sorption-desorption cycles, are regenerated by passing a hydrocarbon purge stream, preferably in liquid phase, containing a C3 to C8 normal paraffins, therethrough at atmospheric or superatmospheric pressure and at a temperature below 250 DEG C. and thereafter hydrating the sorbent by contact with a water or steam-containing stream and finally dehydrating the hydrated absorbent by heating to 250 DEG -375 DEG C. The hydration of the absorbent is preferably effected by adding steam or water to the liquid hydrocarbon purge. An example refers to the regeneration of calcium alumino-silicate molecular sieve which had been used for the separation of normal and isoparaffins from gasoline fraction and had been subjected to a series of sorption-desorption cycles. The sorption cycle was effected in liquid phase at a temperature of 93 DEG C. under pressure of 13,6 atmospheres until normal paraffins appeared in the effluent, after which the absorbed normal paraffins were desorbed by passing liquid n-butane at 93 DEG C. and 13,6 atmospheres pressure thereby desorbing the n paraffins on completion of the desorption cycle flow of feed stock was resumed. When the capacity of the absorbent had declined after successive sorption-desorption cycles, the residual hydrocarbon was withdrawn from the bed which was flushed with liquid n-butane at 100 DEG C. for eight hours, followed by passage of liquid n-butane saturated with water at 110 DEG C. Nitrogen was then passed through at 116 DEG C. and atmospheric pressure and the temperature raised to 316 DEG C. The sieve was cooled to 116 DEG C. after which the sieves were successively treated with vaporized n-butane and then at 93 DEG C. and 13,6 atmospheres with liquid n-butane before being placed on cycle again.

Title: Shrinkproofing keratinic textile materials through reaction with polyisocyanates in conjunction with active hydrogen containing compounds
IPC: D06M15/564
Filed: 1963-10-02
Abstract: Structures containing keratin fibres are shrinkproofed and permanent configurations and mechanical effects, e.g. pleating, crimping and calendering, are set therein by reacting them with a polyfunctional isocyanate compound containing at least two groups which are isocyanate or isothiocyanate groups and a monomeric polyfunctional compound containing as the functional groups hydroxyl, carboxyl, sulphydryl or amino groups. The isocyanate compound may be an aryl, alicyclic or alkylene diisocyanate or diisothiocyanate. The monomeric polyfunctional compound may be an aliphatic compound containing at least two OH or SH groups including ethylenically unsaturated polyols, a di-, tri- or tetraphenylol compound, an alkandamine or an aliphatic or aromatic polyfunctional acid. The isocyanate compound and the monomeric polyfunctional compound may be applied to the fibres as a solution in a non-reactive organic solvent, e.g. a halogenated hydrocarbon, an aromatic hydrocarbon, n-butyl acetate, ether or phosphate, p-dioxane, ethyl oxtate, methyl isobutyl ketone, pyridine, quinoline, N,N-dimethyl formamide or acetamide or 2,2,4-trimethyl pentane, by padding, immersing, spraying or from applicator rolls, or as aqueous dispersions when the isocyanate groups are blocked by reaction with tertiary alcohols, secondary aromatic amines which contain only one group having a hydrogen atom reactive with an isocyanate group, mercaptamo, lactamo, imides, monohydric phenols or compounds containing enolizable hydrogen. The treating solution may also contain a catalyst and a silicone resin. Numerous examples of suitable isocyanate compounds, polyfunctional compounds, catalysts and isocyanate group blocking compounds are given. After impregnation the fibres may be dried and cured by heating to 220 DEG -260 DEG F., aged for 12-24 hours, scoured and dyed with premetallized or acid dyes. During the impregnation the fibres and solutions are preferably maintained at a pH value of 3-9. Fabrics comprising wool alone or in admixture with synthetic polyamide, polyester, acrylic, cellulose acetate, viscose rayon or cotton fibres may be treated. Other suitable keratin fibres are mohair, alpaca, cashmere, vicuna, guanaco, camel hair or llama. In inserting a desired configuration, e.g. pleat, in a fabric, the fabric may be impregnated, arranged in the configuration and cured. Alternatively the fabric may be impregnated, dried, made into garments, pressed into the desired configuration and cured. Reference is also made to crimped yarns and crimped stretch fabrics. Crimped yarns may be obtained by knitting a yarn, impregnating, curing and unravelling the knitted fabric.

Patent ES-348302-A1 (ES)
Title: Complementary mos transistor integrated circuits with inversion layer formed by ionic discharge bombardment
IPC: H01L21/8238
Filed: 1967-12-15
Abstract: A monolithic semi-conductor integrated circuit comprises a substrate containing a complementary (i.e. opposite connecting types) pair of insulated gate field effect transistors. Fig. 1 shows an N-type substrate 2 with a first F.E.T. comprising P-type source 6 and drain 8 regions and gate electrode 18 on simulating layer 16 over channel region 10. The second F.E.T. comprises N-type source 22 and drain 24 regions in P-type zone 36 with gate electrode 34 over insulating layer 32 the production process is fully described. P-type zone 36 is produced by diffusing boron in two stages (the upper surface of the oxide masking being removed after the first stage) into a 5 ohm cm. N-type silicon wafer 2. Masking, deposition and diffusing techniques utilizing boron nitride and phosphorus pentoxide are used to provide source and drain regions 6, 8, 22 and 24. The channel insulating regions 16 and 32 are provided by passing dry oxygen to form a first oxide layer 500 which, depositing a 200 layer of doped oxide by decomposition of a mixture of tetraethylorthosilane, trimethylphosphate and argon and then growing a third 100 thick layer of silicon dioxide after the first and last oxidizing step the dimer is cooled in dry oxygen. The doped layer discourages the formation of an uncontrolled channel inversion layer. Photoresist masking is used to expose the source and drain regions to ion bombardment in argon which improves adherence of aluminium which is then evaporated on to form contact electrodes. The treatment is repeated to provide gate electrode 18 and a thicker aluminium coating on regions 6 and 8 and the aluminium layers are then alloyed to form ohmic contacts. A third ionic bombardment is used to create acceptor sites in the channel oxide layer 32 to facilitate formation of the N-type inversion layer and another coating of aluminium is provided forming the source, drain and gate electrodes. The semi-conductor material may consist of Ge, Si, or GaAs. Fig. 11 shows an inverter circuit utilizing the device. The two gate electrodes are connected to input lead 94 and the two drain electrodes connected together by lead 96. P-type source electrode 82 is connected to a potential Vb. If V b is applied at input 94, P-type channel transistor 3 is cut off and N-type channel transistor 5 conducts to provide zero volts at output 98 similarly zero volts at input 94 means the P-type channel conducts and the N-type channel is cut off to provide potential V b at output 98.

Title: Compressor lubricating system
IPC: F16C3/14
Filed: 1968-07-12
Abstract: A rotatable body, such as a shaft 22 of a motor-compressor unit, has an axial bore 28 through which lubricant is forced, the axial bore having a first discharge port 62 through which lubricant is centrifuged and directed within a predetermined angular range when the body rotates at a first speed, and the axial bore having a second discharge port 60 through which lubricant is also centrifuged when the body rotates at a second speed. The combined discharges of lubricant when the body rotates at the second speed are together directed within the same predetermined angular range as the predetermined angular range through which lubricant from the first discharge port is directed, that is when the body rotates at a first speed. A compressor 20, Fig. 1, and a motor 18 are mounted within a sealed shell 16. The compressor shaft 22 is mounted in bearings 23, 24, has an extension 25 which serves as a shaft for the motor 18, and has a pump 26 mounted at its lower end. The shaft 22 has a concentric bore 28, Fig. 2 an eccentric bore 32, a port 38 and a helical groove 40 for lubricating the bearing 23 a radial port 50, Fig. 3, for lubricating the bearing 24 and a port 46, Fig. 5, for lubricating a piston and cylinder 42, 44, Fig. 1. Excess lubricant, which does not pass through the ports 38, 46 and 50, passes through the bore 32 and through a port 62, Fig. 3, when the shaft is rotating at a first speed or passes through both the port 62 and a port 60, Fig. 2, when the shaft is rotating at a second speed. The arrangement and construction of the ports 60 and 62 ensures that the excess lubricant leaves the shaft 22 in a predetermined direction so that substantially all the excess lubricant contacts the shell 16 and is thereby cooled.

Patent ES-360401-A1 (ES)
Title: Method for making sliding clasp fasteners
IPC: B29D5/06
Filed: 1968-11-18
Abstract: A method of making sliding clasp fasteners having interlocking wire helices comprises heating helical wires of thermoplastics material to a first temperature ensuring their approximate dimensional stability, sewing the stable helical wires to stringer tapes made of synthetic fibres by means of a synthetic thread, the synthetic thread and synthetic fibres being of thermoplastics material and finally heating the resultant fasteners at a temperature near but below the softening temperature of the or at least one of the thermoplastics material. The helical wires sewn to two stringers may be interlocked before the second heating operation. In one embodiment the same thermoplastics material, e.g. a polyamide or polyester, is used for the thread, wires and stringers. In alternatives, the stringers are made of a thermoplastics material having a higher melting temperature than the thermoplastics material of the wires and thread, and the stringers can be heated to the first temperature before the helical wires are sewn on. During the second heating operation, the convolutions of the wires shrink, the wires thicken, the thread shrinks and thickens, and the stringers shrink and thicken thus forming a strong anchorage of the helical wires to the stringers. Also the clearance between adjacent interengaging locking members is reduced to obtain better interlocking. The second heating operation may be carried out either in dry conditions, e.g. by high-frequency, hot air or laser beams, or in moist conditions e.g. in or above a bath of high-temperature liquids, e.g. liquid salt or metal, which liquid is soluble in water. Nylon may also be used for the thread and stringers. Reference has been directed by the Comptroller to Specification 997,612.
