Patent ES-352076-A1 (ES)
Title: Process for the recovery of micro-organisms
IPC: C12C11/00
Filed: 1968-03-16
Abstract: A mixture consisting of or containing a microorganism and aqueous phase is treated to reduce the PH of the aqueous phase, the treated mixture is subjected to a phase separation treatment (decantation) to remove part of the aqueous phase, the residual mixture is treated with a diluent which is a water-soluble oxygen-containing organic compound having a specific gravity less than 1 whereby the specific gravity of the aqueous phase is reduced, and the treated residual mixture is centrifuged to recover a fraction having an enhanced concentration of micro-organism. Adjustment of the pH may be effected with phosphoric, sulphuric or hydrochloric acids. Diluents: ethanol, propanol, isopropanol, n-butanol, 2-butanol and acetone. The diluent is added to the mixture to be treated in a ratio, by weight, in the range 0À5:1 to 2:1. Many species and strains of micro-organisms (yeasts, moulds and bacteria) are particularly mentioned. The process may be employed for the treatment of a broth obtained in the aerobic cultivation of a micro-organism upon a hydrocarbon substrate. The substrate may be a mixture containing metabolisable hydrocarbons and non-metabolisable hydrocarbons. According to an example, the broth obtained from the cultivation of Nocardia erythropolis on a gas oil of specified characteristics was acidified by addition of 5N sulphuric acid until the pH had fallen to 2À5. Two liquid phases were obtained and the upper phase, containing the micro-organism and residual hydrocarbon, was separated by decantation, stirred with an equal volume of ethanol and then centrifuged at 10, 00 g. A paste containing micro-organisms, recovered from the centrifuge, was diluted with four times its volume of ethanol, again centrifuged at 10, 000 g and the product, free of hydrocarbons and ethanol, was then dried. No phase separation took place when the centrifuging was carried out without such addition of ethanol. A further example relates to the recovery of micro-organism from a cultivation broth containing as substrate C9-C19 normal paraffins obtained from a petroleum kerosene fraction by molecular sieve extraction.

Title: Method for suspension-polymerizing vinyl chloride
IPC: C08F14/06
Filed: 1971-09-02
Abstract: Vinyl chloride or a mixture of vinyl monomers containing vinyl chloride as its main component, and an aqueous medium containing a protective colloidal substance and an anionic surface active agent are subjected to an initial stirring, in the presence of an oil-soluble catalyst. Before the rate degree of conversion reaches 30 percent, an inorganic polyvalent metal salt and/or an amine hydrochloride is added to the polymerization system. The anionic surface active agent is thereby rendered water-insoluble. The polymerization is then completed. A polymer having uniform particle size distribution, superior porosity and a high rate of plasticizer absorption is produced.

Patent ES-441413-A1 (ES)
Title: Method of producing plastic containers for storage of goods under pressure
IPC: B29C49/36
Filed: 1975-09-23
Abstract: A method of producing a form retaining container made of synthetic plastic material comprising feeding a plastic material in liquid state onto a male member to provide a layer on the male member constituting a blank for the container. The layer is cooled to prevent crystallization of the material. The thus cooled blank is placed into a mold cavity having an interior configuration corresponding to the desired outer shape of the container to be produced. The layer is inflated into conformity with the mold cavity. The configuration of the mold cavity is such that the blank undergoes biaxial stretching in a middle region of the container by at least 1.5 times while the mouth and part of the bottom of the container will be formed by biaxially stretching the blank less than 1.5 times. The inflated blank is then heated until curing is completed and then the blank is removed from the mold.
Patent ES-448319-A1 (ES)
Title: Parallelepipedic packing container together with a method for its manufacture
IPC: B65B9/087
Filed: 1976-05-28
Abstract: Parallelepipedic packing containers are made and filled in succession by passing a continuous web of packaging material over a forming device which converts the web into tubular form with an overlapped longitudinal seam. The tube is then filled with the intended contents, e.g., a liquid and is then divided off into individual packing containers by first pressing the tube transversely at longitudinally spaced intervals along broad zones and the opposite sides of the flattened tube are heat-sealed to each other along two narrow sealing regions close to the opposite base lines of the flattened zone while the remaining portions of the flattened zone remain non-sealed. The filled portion of the packing container between successive flattened zones is then reformed into the desired parallelepipedic shape, and the packages are then separated from each other by cutting through the non-sealed portion of the flattened zones thus leaving fins which are then folded down against the opposite side walls of the container to stiffen and reinforce the same. The cutting of the double-walled, non-sealed flattened zone is done quite closely to the narrow sealing regions and in such manner that the fins formed on each package have a single material thickness along substantially the full length of the sealing regions.
Patent ES-455869-A1 (ES)
Title: Method of adhering and fixing tbeenail to blind hole for wood working
IPC: B27F4/00
Filed: 1977-02-11
Abstract: Dowels are inserted and bonded with adhesive, particularly wooden dowels or pins into blind holes, for joining wooden parts for furniture. The dowels are pretreated with a set quantity of liq. adhesive e.g. vinyl cement in aqueous solution or dispersion etc. The set amount of adhesive is introduced first into small containers or geometrical capsules which are placed in the holes and are crushed over the bottom of the hole when the dowel is driven in and the liq. contents are spread out over the surfaces to be bonded. The capsules apply the required quantity of adhesive and enable it to be stored and handled easily without drying out or curing before use. The capsule (C) is small enough to fit easily into the hole (F). In mass production, the method can be mechanised by allowing the capsules to drop down a tube into position and by operating a ram to push each dowel forwards.

Title: Apparatus for the continuous fabrication of cellular products of a thermosetting resin
IPC: B29K105/04
Filed: 1977-05-11
Abstract: A method for the continuous fabrication of blankets or sheets of expanded phenolic resin displaying a hard skin on each of their sides, according to which a mixture, comprising in particular a resole resin, a blowing agent and a hardening catalyst is placed on an essentially flat surface of a moving conveyor, is completely expanded, and is conformed eventually between two parallel surfaces entrained in the same direction, the second surface being located above and substantially parallel to and able to move at the same speed as the moving surface, characterized in that, in a first stage, after having been distributed at the surrounding temperature and in the liquid state along the whole width of the surface of the transport component, in such a way so as to comprise a blanket of expandable liquid mixture essentially uniform in thickness, the expandable mixture is conveyed in the open air towards the conformation surfaces while being submitted to a heating so that it expands, the degree of heating and the length of the path in the open air being chosen in a way that the upper skin loses its stickiness before the complete expansion of the mixture and that after the complete expansion, the obtained expanded mass reaches an immediate hardening state, the upper skin remaining supple and unsticky and then the expanded mass is formed by the exertion of pressure on its free side at the time of entry between the conformation surfaces, thus reducing the thickness of the mass to its definitive value and finally the hardening of the resin is completed by maintaining the pressure and the heat during the passage between the conformation surfaces.

The markings may have the shape of equidistantly disposed teeth of uniform width and may be provided on the piston rod or on a piston coolant carrying telescopic tube. The sensing means may be of an inductive type which generates control pulses whenever a marking is passing by. The signals from the transducer and the sensing means are transmitted to an electronic calculator associated with a display for computing and visualizing the mean indicated pressure and other engine parameters.
