Title: Process and apparatus for automating a vacuum degassing stage of aluminium alloys.
IPC: C22B21/06
Filed: 1980-11-27
Abstract: Apparatus and process for automating a vacuum degasification cycle for metal alloys, particularly aluminum alloys. The process comprises adjusting the degasification speed to sequentially correspond to a plurality of sets of degasification speed parameters. Each set of degasification speed parameters corresponds to a predetermined desired degasification speed. The degasification speed may be adjusted by adjusting the vacuum surrounding the alloy. The degasification speed is triggered to change from corresponding to one set of parameters to another set of parameters by the sensing of a series of predetermined partial pressures of gas in the alloy. The apparatus includes an inlet-outlet assembly for transforming given indications into a numerical form for the parameters of the degasification cycle and a calculator assembly adapted to transform the speed of degasification into variations of theoretical partial pressure and to regulate the pressure in the enclosure of the furnace to obtain an identical variation to that required based upon the indications of the standard curve placed in the assembly memories. Several furnaces may be regulated. The temperature of the metal may be regulated at a level equivalent to that required before casting. The apparatus can include a microprocessor.

Title: Method for moulding an article from plastic material
IPC: B29C49/42
Filed: 1981-01-21
Abstract: An article (11) of thermoplastic material is moulded from a parison (10) in which certain parts (17,16) of the parison are re-formed while other parts (13,12,20) retain their shape. A difference in pressure is applied to the wall of the parison during the re-forming process. Material in the parison is also moved in the direction of those parts of the parison which are to be re-formed, whereby attenuation of the material may be avoided entirely, if so desired, also in those parts which are to be re-formed. The invention enables the parison for a bottle to be re-formed to an extent which is small by comparison with the thickness of the material, for example the so-called "neck support" ring and the so-called "pilfer proof" ring, starting with a tube of oriented material. In a device for the application of the invention the elements (22,21,25) are in contact with the parts (13,12,20) of the parison. Between the elements, which are movable relative to each other, are to be found depressions (27,26) in which the parts (17,16) are re-formed. When the elements (22,21,25) are moved towards each other, the size of the depressions is reduced in the direction of the movement.

Title: Filter to purify cadaveric exhaust gas from metal coffin - has reverse flow by=pass to prevent implosion during air transport
IPC: A61G17/00
Filed: 1981-06-02
Abstract: Filter to purify cadaveric gases exhausted from a coffin to avoid excessive internal pressure build-up and danger of explosion. This filter is partic. suitable for metal coffins used for the transport by air of cadavers, i.e. when an excess internal pressure may be experienced due to a sudden loss of altitude. The filter is now provided with a non-return, reverse flow bypass so that a sharp rise in external pressure will occasion an immediate inflow of air to equalise internal and external pressures. Ther is now no danger of an implosion in these circumstances. The non-return valve is pref. an elastic sleeve over a perforated exhaust pipe.

Patent ES-8303116-A1 (ES)
Title: Disintegrating apparatus and its operation method.
IPC: B02C13/288
Filed: 1981-09-15
Abstract: A disintegrator for pulverizing substances of specific natures, having two rotors driven in opposite directions, is taught. The rotors carrying at least four rows of scoops are arranged concentrically in rings and engage alternately in each other, the said scoops transporting the substance from the inside, through the rows of scoops, to the outside and being inclined forwardly and outwardly in the direction of rotation. The scoops are made wear-resistant, and the rotors are made suitable for high-speed operation, in that the scoops are curved substantially like radial turbine blades, the concave curvature being located in each case at the front, as seen in the direction of rotation, and in that the rotors are secured to respective hollow shafts mounted rotatably upon a fixed common axis. This design produces a turbo-action which allows pulverization to take place as a result of repeated collision between particles of the substance in free flight. This makes it possible to operate the rotors at rotational speeds which produce extremely effective pulverization and activation. In order to obtain the best results, the disintegrator is operated according to a specific method.
