Patent ES-259163-A1 (ES)
Title: Improvements in and relating to the production of staple fibres
IPC: D01F6/18
Filed: 1960-06-23
Abstract: Staple polyacrylonitrile fibres of increased potential shrinkage are produced by stretching a bundle of continuous polyacrylonitrile filaments to a degree sufficient to break the filaments without destroying the cohesion of the bundle, while heating the filaments in a zone. The heated zone is preferably much narrower parallel to the length of the filaments than the width of the bundle and is preferably at or near to the feed end of the stretching zone. The bundle may be passed through the nip of a pair of feed rollers to the nip of a second pair of rollers rotating at a higher peripheral speed to stretch the filaments a breaker draft ratio of, for example, 5,0 to 15,0. The heating elements may be a pair of electrical bar heaters one above and one below the tow which is travelling along a horizontal path, each heater may be partially enclosed in an asbestos box and the filaments may be heated in the short heating zone to a temperature of, for example, 101 DEG to 172 DEG F. The filaments are preferably cooled in a second zone after leaving the heating zone, e.g. by a blast of cold air directed on to them. The cohesive top of staple fibres obtained by breaker drafting of the filaments in the above manner may be forwarded directly to a third pair of rollers which forms the nip entrance to a stuffer box for crimping the fibres. "Potential shrinkage" is defined as the ability of the staple fibres to contract in steam or hot aqueous liquids and is increased by the process of the invention, which also produces fibres of improved uniformity of staple length. The fibres may be homopolymers of acrylonitrile or copolymers containing at least 80% of acrylonitrile.

Title: Process and apparatus for improving fats
IPC: C11B3/10
Filed: 1965-03-20
Abstract: Liquid phase processes for refining glyceride oils by treating the oil in liquid condition with an aqueous liquid treating agent under conditions providing numerous interfaces between the two liquids at which the contaminants are extracted from the oil by the aqueous liquid at said interfaces and removed in solution, are characterized in that the oil and aqueous liquid are separately preheated and the treatment is effected continuously at a temperature of 75-160 DEG C. under a pressure above the saturated vapour pressure of water at the temperature of treatment, in a bed of chemically inert packing material of uniform depth and having a free space amounting to 30-90% of its volume, by causing each of said liquids, while free from occluded or dissolved gases or floating impurities to make random contacts with the other while flowing along tortuous paths through said bed, and subsequently separating the oil and aqueous liquids by virtue of their different specific gravities, substantially all the extraction effected occurring during passage through the bed. This procedure is applicable to neutralisation with aqueous alkali washing soap from the oil after neutralization, using neutral or slightly alkaline water which may contain salt and post-desliming using, for example, aqueous alkaline sodium silicate. More than one of such processes may be carried out, e.g. a washing stage may follow immediately after a neutralization stage, both stages using the stated procedure. The oil and treating agent may flow in either counter-current or co-current through the bed, and apparatus for performing the operation either way is described. The packing material may be glass, glazed ceramic, stainless steel, or an inert polymer, such as polypropylene, polyethylene, or polystyrene and may be in the form of beads, rings, or saddles. Also, the material may have a surface which has been made lipophilic. The procedure is also applicable to the treatment of oils in the form of a miscella. Many oils which may be treated are specified.

Title: Improvements in or relating to wave-guides
IPC: H01P11/00
Filed: 1965-08-06
Abstract: A waveguide is made from a thin metallic shell 11 and two layers 13, 14 of synthetic material, e.g. polyester, epoxide or silicone resin, the first (13) of which is applied and polymerized under pressure, the second (14) of which is applied and polymerized without pressure. The shell 11 is shaped, e.g. to rectangular section, from a metallic tube by application of an expansible mandrel consisting of two wedgeshaped parts. A four-part mandrel may be used to shape cross-sections having rounded shorter sides. In order to absorb differential expansion between metal and resin, a layer of suitable material may be interposed between the shell 11 and the layer 13. A two-part mould is used for application of layer 13. Both layers may incorporate several windings of glass fibre which are wound alternately in opposite directions. The outer layer 14, applied without a mould, serves for location of flanges 2. An end portion 1 la of the metallic shell is bent into the form of a flange and attached to the outer surface of the flange 2 by means of an adhesive layer of synthetic elastomer whereby a sealing contact between adjacent sections is achieved.

Title: An installation comprising a plurality of carrier elements and driving means for displacing them along a track
IPC: B65G1/10
Filed: 1969-01-04
Abstract: In the propulsion system of Specification 1,164,871, the disengagement of a carrier element from the drive member 19 is facilitated at the end of the stroke of the latter by giving it a small acceleration. This enables the pin 23 to be withdrawn from a hole 33 in the member 19 by means of a spring 241 provided handle 22 is in its 'disengaged' position. The member 19 is reciprocated by a double acting hydraulic piston and cylinder unit 43 (see Division F1) having a pair of heads 44, 45, one of which is supplied with hydraulic fluid from a pump 57 via a reversing valve 58, the other of which is connected to a sump via the valve 58 and a variable regulator 59. Near the end of a stroke a valve 63 is actuated to provide a second drain path, enabling a small acceleration of the member 19 to take place. The valve 63 also actuates the reversing valve 58 to commence the return stroke of member 19.

Patent ES-397563-A1 (ES)
Title: Manufacture of thin-walled containers
IPC: F17C1/00
Filed: 1971-12-01
Abstract: Metal containers, particularly for beer, have been made from stainless steel which is compatable with beer or aluminium which is specially coated to make a compatable inner surface. The stainless steel container is expensive when the wall thickness is such as to withstand rough handling and the cheaper aluminium container has a limited life depending on the internal coating. The present invention provides a double wall container of which the inner wall is of thin stainless steel. The invention solves the hitherto insurmountable problems of forming a thin walled inner vessel and expanding it inside an outer vessel so that the resulting inner vessel is without crevices which would otherwise be extremely difficult to clean to meet strict hygiene regulations.
