Title: Closed channel disk for a gas turbine engine
IPC: F01D5/02
Filed: 1976-03-02
Abstract: A disk having a closed channel construction and which is especially suited for supporting the rotating blades of a gas turbine engine is disclosed. In one embodiment, the disk supports the fan blades of a turbofan engine which extend radially therefrom.

Title: Metallurgical process using oxygen
IPC: C22B15/06
Filed: 1976-04-01
Abstract: A continuous autogenous multi-stage process for converting non-ferrous metal sulfides, in an oscillating, elongated, gently sloped, sealed, tiltable, rounded cross-section furnace, discharging crude metal or low-iron matte at one end, and silicate slag and sulfur dioxide-rich gas at the other end. The concentrates, fluxes, commercial oxygen, sulfur dioxide, a carbonaceous reducing agent and optionally other materials are introduced into the furnace in stages to provide a molten bath of slag and matte flowing countercurrently. Slag scavenging is accomplished by deconverting to produce low grade, cleansing matte in situ in the slag layer, followed by settling. At least a substantial proportion of the commercial oxygen is continuously blown in through injectors extending through the refractory lining of the vessel and communicating with its interior below the bath surface, where necessary with a protective fluid, desirably surrounding the oxygen. Oscillation of the converter causes the injected gases to sweep back and forth through the bath, and distributes the solids over its surface to provide bath turbulence and interphase contact. Off-gases are desirably recycled. Flexible control means and special apparatus are disclosed.
Patent ES-449312-A1 (ES)
Title: Process for preparing aqueous dispersions of lipid spherules and aqueous dispersions of such lipid spherules
IPC: C09K23/42
Filed: 1976-06-28
Abstract: The spherules have a diameter of 1000 to 50,000 ANGSTROM and consist of molecular layers of lipid compounds whose molecule contains a hydrophilic ionic group and a lipophilic group. They contain an aqueous phase to be encapsulated, it being possible for this aqueous phase to contain dissolved substances with cosmetic, alimentary or pharmaceutical action. Such a dispersion is prepared, for example, by homogenising a mixture of sphingomyelin and of a glucose solution, by adding a solution of NaCl or KCl and vigorously agitating the whole. The spherules obtained have a diameter of approximately 2 microns and are therefore sufficiently large not to pass through the skin, and this is advantageous in the case of cosmetic applications.
Patent ES-456130-A1 (ES)
Title: Apparatus for mixing a vaporized liquid fuel with air
IPC: F02M19/00
Filed: 1977-02-21
Abstract: A mixing apparatus for mixing a vaporized liquid fuel with air to develop a combustible air/fuel mixture is described. A finned swirl inducing member having a centrally located aperture is positioned downstream from a metering venturi and upstream from a plain tube mixing section. The centrally positioned aperture is sized and spaced to allow passage of a stream of vaporized liquid fuel delivered to the low pressure zone formed by a metering venturi. The fin members of the swirler are operative to cause a swirl of the air stream passing through the metering venturi. The swirling air stream prevents any direct contact between the vapor stream and the relatively cool side walls of the mixing section while causing mixing action between the interiorly constrained vaporized liquid fuel stream and the inner portions of the air swirl.

Patent ES-489525-A1 (ES)
Title: Pressure vessel
IPC: F16L55/053
Filed: 1980-03-13
Abstract: A pressure vessel comprises a rigid envelope enclosing a chamber and consisting of a body and cover, the rim of the cover being inserted in the rim of the body, and the body and cover being secured to each other. Defined between the overlapping rims is an annular groove adapted to receive a flange at the periphery of a circular flexible diaphragm, which serves to divide the chamber into two compartments of variable volume. There is a fluid orifice in both the body and cover, the two orifices being axially alinged and communicating one with each variable-volume compartment. To ensure a good seal between the compartments, and to enhance retention of the flange in the groove, the annular groove is of less height and greater width than the flange on the diaphragm, before the flange is sandwiched into the groove between the rims of the cover and body, so that the flange is deformed into the groove, when the cover is assembled on the body. The rims on the cover and body may be shouldered for good co-operation therebetween and the shoulder reinforced on the outside of the vessel so that it does not collapse when the vessel is pressurized.

Title: Drive chain
IPC: B65G23/16
Filed: 1982-02-24
Abstract: A multiple strand drive chain for transmitting power from toothed sprockets to an endless belt constructed of toothed links.
