Title: Method and device for the distillation of water from saline solutions
IPC: B01D3/06
Filed: 1966-10-06
Abstract: Sea water is desalinated in multi-stage flash evaporator comprising four coaxial columns 14, 16, 18, 20 which form an axial chamber 13 and three annular chambers 15, 17, 19, arranged at progressively increasing height, each chamber communicating with the adjacent chamber through lower openings 30 and upper openings 26, 28. The arrangement is such that, when the evaporator is in operation, there is an automatic drop in pressure from chamber 13 to chamber 20. The sea water to be distilled, after flowing through heat exchanger 33 and heater 32, is introduced into the lower section of chamber 13. Cold distilled water is supplied to the upper section of chamber 20. The sea water rises successively through the lower sections of chambers 13, 15, 17, 19 and distilled water flows successively through the upper sections of the chambers in the reverse direction. Flash evaporation of some of the sea water takes place in the lower section of each chamber and the vapours are condensed by a rain of distilled water 24, distributed by perforated plate 27, in the upper section of the chamber. The droplets of distilled water are received in an annular collector 23 in each chamber, and the liquid then flows through openings 28 into the condenser of the next lower chamber. The required difference in pressure between the chambers is established due to the depth of distilled water above the perforated plate 27 in each chamber. Residual brine is withdrawn from chamber 19 through pipe 34, and is in part recirculated with fresh feed to heater 32 and chamber 13. Warm distilled water is withdrawn from the collector in chamber 13, and is cooled by conducting it through heat exchanger 33. Part of the cool distilled water is withdrawn from the system as product, and the remainder is recirculated to the condenser of chamber 20.

Filed: 1968-09-11
Abstract: A continuous steaming and ironing machine for knitted fabric pieces comprises two, opposed endless circulating belts 3, 7 for feeding the pieces to be ironed a spreading-out roll 4 for uncurling the lateral edges of each fabric piece, the roll 4 being located at the engagement gap 20 of the belts 3, 7 and rotating in a direction opposite to the direction of feeding motion of the fabric pieces and an end edge-uncurling roll 5 associated with the gap 21 between the roll 4 and the belt 3 and which is displaceable relatively to the roll 4. Each fabric piece is pre-steamed in a zone 1 to increase its flexibility and its leading smooth edge is introduced between the belt 3 and the roll 4 which is provided with opposite saw-tooth threads to uncurl the lateral edges of the piece. The roll 5, which is knurled and is mounted on a carriage 5a which has previously been withdrawn, is advanced as soon as the leading edge is gripped between the belt 3 and the roll 4. A resiliently-mounted plate 6 urges the belt 3 towards the roll 4. The upper belt 7, passing around an edge 8 having a nose-shaped profile, prevents re-curling of the edges of the piece as it passes below a hood 9 into a zone in which it is steamed, smoothed and set by steam passing upwardly from a trough 10 into a thermostatically controlled super heating device 11. Excess steam is sucked out by a fan 12. Each fabric piece passes beneath an electricallyheated thermostatically-controlled roll 13 comprising a covered smoothing roll or a polished roll to impart a lustre to the fabric piece which is subsequently cooled by air sucked through an extractor 15 by a fan 14.
Patent ES-366792-A1 (ES)
Title: Method for laminating sheets
IPC: B01J19/10
Filed: 1969-05-05
Abstract: A method of laminating at least two sheets capable of being adhesively united under pressure comprises feeding the sheets, e.g. 1, 2, between two opposed pressing elements 9, 10 providing substantially parallel pressing surfaces, at least one of which elements, e.g. 9, oscillates at a frequency between 10 and 1000 c/s in a direction substantially normal to the sheets, the sheets being compressed in consecutive but overlapping sections thereof. In one apparatus shown for performing the method sheets 1, 2 are fed via heaters 23, 24 to the passage between a fixed element 10 and a vertically oscillated element 9. The sheets are advanced by belts 25, 26 at such a rate that the portions compressed between the elements 9, 10 in successive cycles overlap. In a second apparatus both loading elements are connected via spring elements to vertically oscillating members with the result that the elements when pressed together first compress the sheets passing between them and then advance the sheets before being released therefrom. In a further apparatus both loading elements are arranged for oscillation in two directions i.e. normal to the planes of the sheets and parallel to their direction of motion. In this apparatus the elements are actuated to compress the sheets, advance the compressed sheets, release the compression, and return to their original position. In further apparatuses the loading elements comprise a rotating roller and an oscillating element having a concave surface co-operating therewith, or an oscillating roller and a co-operating fixed element having a concave surface, or two fixed blocks in the surface of one of which is embedded an inflatable element the interior of which is connected to a pneumatic or hydraulic source of oscillating pressure. In all the apparatus except the last the oscillations may be produced by mechanical, hydraulic, pneumatic or electromagnetic means and the loading elements may be supported by elastic means. The lamination may be in selected areas only e.g. along stipes, and this may be effected by using divided loading elements. The apparatus may include cooling and/or drying means to consolidate the adhesion between the sheets. The sheets may be of thermoplastic or thermosetting plastics combined with each other or with sheets of metal, paper, wood, or mineral composition. They may be in the form of film, fabric, non-woven fabric, board, veneer, or laminates. Their surfaces may be impermeable or permeable, smooth, or rough. In one example a plastics foam is laminated between two paper sheets. The sheets may be held together by adhesive sprayed or coated on to their surfaces, or, when of thermoplastics material, by heating such material.
