Title: Herbicidal dichloroanilides of carboxylic acids and their preparation and use
IPC: A01N37/22
Filed: 1959-01-28
Abstract: The invention comprises 3,4-dichloroanilides of propionic, and alpha-methyl-valeric acids. The compounds may be prepared by dissolving 3,4-dichloro-aniline in a volatile, inert, organic solvent and reacting it with the appropriate carboxylic acid or its acid anhydride or halide. When an acid halide is used an alkaline reagent is supplied to take up the hydrogen halide split out. When the carboxylic acid itself is used, the mixture is heated under reflux with removal of water carried over by the azeotroping liquid. Solvents specified are naphtha, benzene, toluene, xylene, di- and trichloroethane, and dichloropropane. The reaction may be carried out at about 10 DEG to 50 DEG C. when an acyl halide or anhydride is used or at 50 DEG -150 DEG C. when a carboxylic acid is used. Examples are given.ALSO:The invention comprises herbicidal compositions containing a 3,4-dichloroanilide of propionic, or alpha-methyl valeric acid, or a mixture thereof, dispersed in a carrier. The compositions may be in the form of aqueous sprays or dusts, preferably containing a surface-active agent. An emulsifiable concentrate may be prepared from isophorone, an aromatic naphtha or xylene or toluene or mixtures thereof together with one or more solvent-emulsifying agents and the 3,4-dichloroanilides. Additional components may be e.g. methenol, methoxyethanol or butoxyethanol. Emulsifying agents mentioned are calcium dodecylbenzene sulphonate, sodium dioctylsulphosuccinate, octyl and nonyl phenoxypolyethoxy ethanol, ethylene oxide condensates of longchained alcohols, carboxylic acids, thiols, or amines, condensates of polyglycerols and fatty acids, with or without a resin-forming acid such as phthalic acid, or such compounds as oleylbenzyldimethylammonium chloride, or dodecylbenzyltrimethylammonium chloride or bromide.

Patent ES-262727-A1 (ES)
Title: Improvements in curing organopolysiloxanes
IPC: C08H/
Filed: 1960-11-24
Abstract: A hydroxy-terminated diorganosiloxane is rapidly cured by cross-linking it in the presence of a combined accelerator comprising mono-, di- or tri-chloracetic acid and an organic tin compound, using as the cross-linking agent an alkyl orthosilicate or a partial hydrolysate thereof. The siloxane may contain alkyl, alkenyl, cycloaliphatic, aryl, alkaryl, aralkyl or halo-hydrocarbon radicals. Tin compounds specified are dibutyl tin-dilaurate, -dibenzoate, -adipate and -di(2-ethylhexoate). Preferably the silicate is used in amount of from 0,1 to 10% and the tin compound and the chloracetic acid are each used in amount of from 0,01 to 5%, based on the weight of the siloxane. Fillers, e.g. silicas, Al2O3, TiO2 and C blacks, may also be added. Although the components may be mixed together, advantageously a part of the siloxane may be mixed with a part or all of the filler and the silicate, the remainder of the siloxane being separately mixed with any remaining filler and all the accelerator, whereupon the resulting compositions are rapidly mixed together. In an Example (2) a dimethylsiloxane oil containing Si-OH groups is mixed with silica fillers and heated at 135 DEG -140 DEG C. and freed of volatiles to yield a paste A one portion was then mixed with ethyl orthosilicate and chromium oxide to yield a paste B, and another portion was mixed with trichloracetic acid and dibutyl tin dilaurate to give paste C equal quantities of B and C were then mixed together, introduced into a metal mould and left in moist air the composition cured in 4 minutes. Uses: For sticking (silicone rubbers, metal, wood, &c.), caulking, coating articles, lining, protecting supports and making moulded articles.
Patent ES-265361-A1 (ES)
Title: Process and apparatus for the manufacture of agglomerated bodies from mineral fibres, particularly glass fibres
IPC: B28B1/52
Filed: 1961-03-03
Abstract: The invention comprises a process for the manufacture of agglomerated bodies from mineral fibres including the steps of forming the fibres and depositing them on transporting means, for example a conveyer belt, wherein, for the purpose of agglomerating the fibres, a hot plaster wash is applied to the fibres (i) before they are deposited on the transporting means, or (ii) whilst they are on the transporting means, or (iii) both before they are deposited on the transporting means and whilst they are on the transporting means. The invention also comprises apparatus for carrying out the above process which comprises two or more fibre-forming devices placed successively after each other above the transporting means, a hot plaster wash spraying device being associated with each fibre-forming device for spraying hot plaster wash on to the fibres. The hot plaster wash is preferably applied to the fibres, for example by spraying, soon after they leave a device for forming the fibres. A mat formed by the fibres to which the hot wash has been applied may be rolled and cooled during the setting of the plaster. Any common plaster, for example, plaster of Paris, may be used and inert fillers, colouring matter, accelerators, setting delayers, hardeners, or organic compounds such as polyvinyl alcohol, may be added. Minerals such as barium sulphate, kaolin and mica which decompose endothermally at temperatures of 500 to 700 DEG C. may also be incorporated in the plaster. The plaster wash is generally applied at a temperature above 70 DEG C. and the quantity of mixing water is about 70 to 80% by weight of the plaster. The proportion of plaster to fibres may vary and may also vary through the depth of the product. Thus products may be formed having a high proportion of plaster in the surface regions and a low proportion in the central region, or vice versa, the latter products being useful as fire-retardent panels. An example illustrates the process using apparatus consisting of three high speed spinners placed in series above a conveyer belt, each spinner producing streamlets of material which are attenuated into fine fibres by the action of currents of gas. The attenuated fibres are then sprayed with the hot plaster wash by means of atomisers placed below the spinners, the treated fibres then falling on to a conveyer belt. Optionally, layers of plaster may be introduced by means of distributers placed above the conveyer belt and between successive spinners.

Title: Pneumatic cleaning device for centrosymmetrical textile machines
IPC: D01H11/00
Filed: 1967-08-04
Abstract: A pneumatic cleaning arrangement for a circular machine comprises a blower having an impeller 31 driven by an electric motor 29 and positioned above the machine cylinder. The blower is housed in a casing 22 provided with outlets connected to ducting 23, 43 conveying air from the blower to nozzles or other openings which direct the air towards various parts of the machine such as the yarn guides, tensioners, stop motions and yarn feeding devices. The whole casing and the ducting are mounted on the bobbin support and are caused to be rotated so that the jets of air directed from the ducting impinge in turn on the various components and cause the dust or lint which has settled thereon to be dispersed. The blower casing also has an inlet 32 covered by a filter element which as the casing is rotated draws in the dispersed dust and traps it. A suction head 37 stationarily mounted by the side of the casing removes the dust from the filter element on each revolution of the casing. The blower may be mounted to rotate with the casing or remain stationary within it.

Patent ES-369461-A1 (ES)
Title: Method and apparatus for the preservation of biological substances
IPC: A01N1/02
Filed: 1969-07-12
Abstract: Biological substances such as blood are stored under pressure at below 0 DEG C temperatures, in a substantially non-dilatable vessel. Upon being introduced into the vessel, the temperature of the vessel and the blood are reduced to 4 DEG C when equilibrium has been achieved the blood within the vessel is precompressed at a controlled rate several thousand pounds per square inch by the application of mechanical leverage to a vessel piston. Thereafter, the vessel and blood are reduced to a final temperature from 0 DEG C to -21 DEG C. This temperature reduction, because of the conjunctive effect of the volumetric expansion of the blood and non-dilation of the vessel, self-generates a pressure from 15 to 35,000 p.s.i. The vessel may now be stored at the final temperature and the blood within it maintained without deleterious effects.
