Patent ES-338923-A1 (ES)
Title: Airship
IPC: B64B1/12
Filed: 1967-04-05
Abstract: A non-rigid airship has a collapsible envelope rendered buoyant by steam, the envelope being double-walled to reduce heat losses outwardly of the wall wherein the two skins 10a, 10b, 10c and 13a, 13b, 13c of the walls are joined by tensile connecting elements 11 and bridged by zig-zag formation foil elements 14 which reduce convection losses. The envelope 2 is connected by cables 6 to an intermediate supporting frame 5 attached by structural members to a keel frame 1. The envelope is subdivided into compartments by flexible dividing panels 27 which may, by relative pressures, take up either the concave or convex profiles shown in Fig. 1 and propulsion units 4 and 3 are carried by the envelope at the bow and stern. The bow unit, Fig. 6, may form also a control cabin and gas is delivered from a generator through a duct 18 for discharge from ducts 19 which with the cabin may be swivelled for directional control. The rear unit is similarly constructed (Fig. 7, not shown) though it would not normally have a cabin. The keel 1 is made of tubular elements, which may store fuel, bridged by a bottom panel formed with a tubular section flexible seal to form a space that may be evacuated to anchor the airship to a ground surface. Alternatively, individual suction pads 32, Fig. 1, may be provided. The inner and outer surfaces of the envelope are coated with a hydrophobic layer to reduce, respectively, the absorbsion of condensed steam and the absorbsion of rain water and the reduction of surface resistance.
Patent ES-339853-A1 (ES)
Title: Porous cone cleaner
IPC: B04C5/081
Filed: 1967-04-17
Abstract: A cyclone separator for removing foreign particles from a fluid suspension of solid particles comprises a conical chamber having a porous wall 20, a tangential inlet 10 for introducing the suspension to be cleaned in a chamber at the top of the conical chamber so that it passes in a vortical whirl through the conical chamber, a central outlet 40 for the cleaned suspension, a jacket enclosing the porous wall 20 and connected to a valved supply pipe 60 whereby liquid is forced through the wall 20 to form a layer on the inside surface of the wall, and a tip portion 30 having a non-porous wall and provided with a discharge opening for separated foreign particles. The inside diameter of the large end of the tip portion 30 is greater than that of the small end of the chamber to facilitate discharge of the foreign particles. The separator may be used to remove unwanted particles from wood pulp stock. The liquid forced through the wall 20 may be water and serves to release any light acceptable particles that may become entrapped with the unacceptable heavy particles on the wall of the chamber and cause them to discharge through the outlet 40. The layer of water formed on the wall also serves to protect the wall and to decrease frictional resistance thereby also facilitating the downward discharge of separated foreign partides. The separator may also be used for separating foreign particles from a gaseous suspension of solids. In this case the liquid layer on the wall serves to trap the separated particles and discharge them through the apex of the separating chamber. The liquid may also function as cooling and wear reducing agent when treating hot gases.

Title: Process for making steel wire
IPC: C21D9/52
Filed: 1967-09-25
Abstract: Steel wire or rod is subjected to a continuous patenting heat treatment by heating the work in a furnace e.g. containing tubes through which the wire travels to above the steel's upper critical temperature, e.g. to 1600 F. in an atmosphere of cracked ammonia to prevent decarburization, then passing it from the furnace without air cooling into a first cascade chamber to quench the work by a liquid medium to below the Ar temperature zone e.g. 400 -700 F. to suppress the formation of pro-eutectoid carbides and ferrite, then into a second cascade chamber to reheat the work by a liquid medium to 750-1050 F. to obtain isothermal transformation to upper bainite and fine pearlite structures. The cascade chambers preferably comprise vigorously agitated quenchant, e.g. NaNO 3 -NaNO 2 eutectic or Pb-Bi alloy, which is pumped from a reservoir up into a tray disposed above where it overflows back into the reservoir. The work may be passed from the second cascade chamber into a holding furnace maintained at the same temperature to complete transformation. The heat treatment may be repeated with intermediate cooling to room temperature and drawing. The wire may be given a copper coating prior to drawing to final gauge. The wire may be of highereutectoid steel containing 0À9-1% of C, max. 0À005% each of P and S, max. 0À1% Si and max. 0À002%N.

Title: Method of producing heat and cold-insulating sheet material using a layer of foamed plastics
IPC: B32B27/00
Filed: 1967-10-17
Abstract: A method of producing heat and cold insulating material consisting of or comprising a layer of foamed plastics includes the steps of mixing together at least two basic components which react with one another with one or more activators to form foam, directing the mixture towards the gap 26 between two moving supporting webs 14, 16 and moving the mixture and the webs between web guides in the form of a pair of rolls 10, 12 or bars, and then between gauging plates 50, 52, the distance between the plates determining the thickness of the layer of foam between the webs and this distance being adjustable by moving the plates towards or away from one another, the distance between the rolls or bars also being adjustable. In the device shown for carrying out the method the reaction mixture is deposited as a jet or spray from a nozzle 28 on to the web 14 as the latter passes from a roller 13 to rolls 10, 12. The mixture forms a bulge 15 ahead of the rolls and is reciprocated horizontally to spread the mixture evenly. Alternatively the transverse speed of the nozzle or the flow of mixture may be varied to ensure even spreading. More than one nozzle may be used. The assembly 48 of foaming mixture and webs 14, 16 then passes between roll 10 and adjustable roll 12 and then between plates 50, 52 which may be heated and/or cooled plates. The webs may be advanced by belts 21, 23. The width of the foam is controlled by edge guide rails or air jets blowing on the foam. One or both of the webs 14, 16 may have an adhesive repellent silicone based coating to enable it or them to be stripped from the set foam. In this case the coated web(s) may be endless. The webs may be of paper, cardboard, plastics material, textiles, metal foil, or veneer. The foam may be produced by the reaction of polyisocyanates with polyether or polyester compounds with tertiary amines, or mixtures of organic tin compounds and water, as activators. An intermediate layer of metal, plastics, organic or inorganic fabric or threads may be inserted in the foam. In a second embodiment the roller 13 and belts 21, 23 are omitted. The materials produced are shock absorbent and may be used in packaging e.g. as boxes, containers, pouches, or in chests.
