Filed: 1974-02-04
Abstract: Unreacted ammonium carbamate contained in urea synthesis effluent obtained by reacting ammonia and carbon dioxide at urea synthesis pressures and temperatures is recovered by a method comprising subjecting the urea synthesis effluent to a three-stage decomposition to decompose the unreacted ammonium carbamate in each stage, the first stage and the second stage of which are operated at a gauge pressure of at least 30 kg/cm2 and a gauge pressure of from 10 to 25 kg/cm2, respectively, absorbing the off-gas resulting from the second stage decomposition in an absorbent to form an aqueous solution of ammonium carbamate and unabsorbed gaseous ammonia, condensing the gaseous ammonia to form recovered liquid ammonia, and absorbing substantially all of the off-gas resulting from the first stage decomposition in the aqueous solution of ammonium carbamate to form recovered ammonium carbamate solution while removing the heat of absorption by indirect heat exchange with the recovered liquid ammonia pressurized to the urea synthesis pressure.

Title: Method and an apparatus for storing heat energy
IPC: F28D20/02
Filed: 1978-11-13
Abstract: A method and an apparatus for storing heat energy in a hybride heat storage apparatus comprising a first and a second material are disclosed, the first and the second materials having different melting temperatures and different densities and being non-mixable. When heat is discharged from the heat storage apparatus, the first material, which has the lower melting temperature, is brought into direct heat exchanging contact with the second material which is essentially in a liquid state by causing droplets of the first material having a lower temperature than the melting temperature of the second material to pass through the second material, whereby the droplets of the first material are heated and may be used in order to give off the heat in an outer circuit, while the second material sets essentially in droplet form. When heat is supplied to the heat storage apparatus, liquid flow channels are formed through the second material, which is essentially in a solid state, whereupon droplets of the first material, which have a higher temperature than the melting temperature of the second material are caused to pass through the flow channels whereby the second material around the flow channels are caused to melt by direct heat exchange. Preferably, the first material has a higher density than the second material, the first material being sprayed or showered onto the material. The hybride heat storage apparatus comprises a vessel containing the first and the second material, the said materials being located in layers on top of each other supply line which comprises a droplet forming apparatus, whereby the first material, which has the lower melting temperature, is divided into droplets and a discharge line for the first material.

Patent ES-485377-A1 (ES)
Title: Drying machine for knitted fabric - which floats between perforated conveyors on pulsing streams of hot air
IPC: F26B13/10
Filed: 1979-10-25
Abstract: A textile drying machine, partic. for jersey fabric, comprises a drying chamber traversed by a pair of perforated conveyor belts arranged one above the other with a gap between them to form a tunnel through which the fabric passes, suspended between streams of air which issue from two series of transverse slots, one above and one below the perforated belts, to produce oppositely directed but staggered air currents which ebb and flow in unison. The slots are arranged in pairs, each pair having a rocking vane which alternately opens and closes each of the slots in opposition to the opening and closing of the neighbouring slots in the same row and the facing slot in the opposite row. The material is dried completely free from tension, in conditions which promote maximum relaxation and shrinkage, enhancing the finish and improving the quality.
Patent ES-489818-A1 (ES)
Title: Weaving machine giving trouble free weaving - has first weft yarn guide and between this and the selvedge, a second yarn guide mounted on shuttle box
IPC: D03D47/34
Filed: 1980-03-21
Abstract: On a gripper shuttle loom, the weft yarn is fed to the gripper at always the same angle, and the cut length is subjected during weaving to only very slight tension. The invention provides a first weft yarn guide and between this and the selvedge, a second yarn guide mounted on the shuttle box or the reed. In relation to the direction of shuttle movement, the second guide offers the same distance in relation to the cloth selvedge, or the holding element, as the first guide offers in relation to the tension device. Using this second guide, a supported length of cut weft is obtd. which remains constant during the movement of the slay. In particular, the cut length held between the second guide and the selvedge is shortened or lengthened during slay movement in accordance with the length of cut yarn between the first guide and the tension device, to obtain a constant length, and reduce the compensatory role previously imposed on the tension device. When the weft yarn is transferred to the gripper element of the shuttle, the yarn angular positioning should be exact, and approximately constant yarn tension should prevail, to provide trouble-free weaving over long periods. The introduction of a sec. yarn guide provides a constant length of weft, cut and supported during slay movement, so that weaving may proceed at a rapid rate.

Title: Device for the control of the mutual removal and approching movement of lateral conveying units in a carton sealing and/or closing machine
IPC: B65B51/06
Filed: 1982-11-27
Abstract: A sliding plunger with rack-shaped opposite sides controls opposite rotations of a pair of rotating sector gears, with which integrally rotate two arms extending up to the proximity of the conveying units. Connecting rods are finally interposed between said arms and said conveying units to transform the rotary motion of the arms into a corresponding translatory motion of said conveying units in opposite senses along fixed rectilinear guides transversally disposed with respect to the carton support base. The control of the sliding of the rack plunger can be given by a pneumatic cylinder or by a hand-control lever. There can be provided adjustable means for limiting the sliding plunger stroke in the sense corresponding to the mutual removal of the conveying units and elastical thrust means acting on the same plunger in the opposite sense. The connecting rods moreover can be provided with a succession of holes, which can be alternatively chosen to change the distance among their points of pivotment with the rotating arms and the conveying units.
