Patent ES-297865-A1 (ES)
Title: Improvements in or relating to flotation cells
IPC: B03D1/14
Filed: 1951-05-14
Abstract: A froth flotation cell comprises a perforated agitator plate 4 which is actuated by an electromagnetic vibrator 2 and of such configuration that it offers greater resistance to the passage of suspension therethrough in one direction than in the other, and discharge orifices 8 from air feed conduits 7, Figs. 2 and 3 (not shown), attached to the agitator plate on the side from which the resistance to the passage is greater. Such an agitator produces, in operation, zones of suspension at a pressure below the normal pressure. The agitator is formed of pressed steel plate having frusto-conical depressions 6, the bottoms of which are formed with apertures 15. Each air feed conduit 7 is welded to the underside of the agitator plate and arranged so that the orifices 8 are adjacent the apertures 15, the inner end of the conduit being in communication with a hollow supporting rod 3 which is supplied with compressed air through its inlet 3. When vibrated in its vertical direction, some of the suspension is passed out through an outlet 9 and a circulatory current is set up in the direction of the arrows 10 during this circulation, some of the suspension passes through the apertures 15 so as to produce a zone of reduced pressure around the orifices 8. The froth is removed by a paddle wheel 13. A series of cells may be grouped around a single vibrator, linkages connecting the agitators with the vibrator.

Title: Initial wheel slip bypassing system
IPC: B60L3/02
Filed: 1968-11-23
Abstract: In an over-speed controlled automatic brake system, for e.g. a locomotive, the over-speed control may be operated by wheel-slip during starting. To overcome this the OVERSPEED DETECTOR is by-passed during starting by a short-period timer. As shown an R.C. timing circuit R1C1 is charged over a " throttle off " contact 16 and a train-motion-relay contact T.M.R. (to prevent operation of the by-pass circuit by throttle closure when the train is running). The timing circuit feeds transistors T1 . . . T4 to energize a cycling relay TC until the charge on C1 leaks away. Relay TC cycles by disconnecting transistor T1 from C1 over its back contact 19. While TC cycles relay TCP is held up by the charging and discharging of capacitors C2, C3 over contacts 20, 21 of TC. With TCP up contact 26 maintains the electropneumatic brake valve EPV closed even if the overspeed relay OS opens.

Title: Covering
IPC: C09J5/00
Filed: 1969-02-20
Abstract: A floor, wall or ceiling surface is covered by applying a liquid, solvent-free cold-curing synthetic resin composition and a curing agent for the resin selected so that the hardening of the resin by the curing agent is not instantaneous, electrostatically depositing textile fibre flock on the surface of the resin before it has hardened to an extent such that the flock particles cannot penetrate, at least partially, the surface and thereafter allowing the completion of the cure of the resin at room temperature. The surface can be jointless composition flooring, a cementbound jointless composition, compositions based on binders such as lime and gypsum and on bitumen or asphalt, concrete, artificial stone, plaster and wood, particularly wooden floors. The term "solvent-free" is defined as not containing a volatile organic solvent. Solvents that participate in the curing reaction may be present, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters. Suitable solventfree compositions are those based on non- thermoplastic polymers such as (1) hydroxyl group-containing compounds such as polyethers, polyesters, alkyd resins, acrylic and epoxy resins (which cure with polyisocyanates), (2) epoxy resins (which cure with the aid of polyamines, amidoamines or ketimines), (3) acrylic compounds or unsaturated polyesters mixed with copolymerizable monomers, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters (which cure with peroxides), (4) polysulphides (which cure with heavy metal peroxides, e.g. lead peroxide or manganese dioxide). The curing agent may be admixed with the resinous materials before processing, or alternatively a curing agent and the resinous material can be applied separately on to the surface by a two-component spray device, or the curing agent can be applied first followed by, in a separate operation, the application of a layer of the resinous material. The resinous materials may contain pigments and/or fillers such as talc, barium sulphate, mica, asbestos, quartz or sand. The compositions may be applied by brushing, roller, spraying, casting or trowelling. Suitable textile fibres are of cotton, coconut, wool, goat hairs, viscose rayon, triacetate or polyamide flock, and are preferably of length 0À3 to 12 mm. The flocking may be carried out using screen diffusers in an electrical hightension field or by means of electrostatic spray guns. The fibres may be of uniform or varying length, or fibres of different length can be incorporated by flocking in two or more successive operations, and fibres of different colours can be used.
