Title: Production of Polyethylene
IPC: C08F10/00
Filed: 1967-10-06
Abstract: Polyethylene is produced by a process which comprises feeding a mixture of ethylene and initiator to an elongated reactor, passing the mixture through a preheat zone wherein the mixture is indirectly heated to 120 to 160 C., passing the preheated mixture through a first reaction zone wherein the preheated mixture is indirectly heated to a peak temperature exceeding 275 C. and most of the ethylene is converted to polyethylene, the temperature profile of the first reaction zone embracing temperatures in the range 120 to 320 C., passing the resultant mixture from the first reaction zone to a first cooling zone wherein the resultant mixture is indirectly cooled to a temperature not exceeding 275 C., adding initiator to the cooled mixture, passing the cooled mixture with added initiator to a second reaction zone wherein the cooled mixture with added initiator is indirectly heated to a peak temperature exceeding 275 C. and additional ethylene is converted to polyethylene, the temperature profile of the second reaction zone embracing temperatures in the range 180 to 320 C., passing the resulting mixture from the second reaction zone to a second cooling zone wherein the resultant mixture from the second reaction zone is indirectly cooled to a temperature not exceeding 275 C., and separating the resulting polyethylene from unreacted ethylene. The process may comprise additional steps of passing cooled mixture with added initiator to further reaction zones with indirect heating and having temperature profiles embracing temperatures in the range 180 to 320 C. The separated ethylene may be recycled to the preheat zone. In examples, (3) ethylene, together with (4) propane as chain transfer agent, is polymerized with oxygen in the first zone and t.-butyl peroxide in the second.

Patent ES-353721-A1 (ES)
Title: Loading ramp
IPC: B63B27/14
Filed: 1968-06-19
Abstract: A loading ramp for use in a ship's side has means for maintaining the ramp substantially at a predetermined inclination. As shown, a ramp 1 is hinged to a cross-beam 3 supported by bogies 6 running in vertical guides 4 at the side of an opening in a ship 5. The bogies are driven by an hydraulic motor 8 via chains 10, energization of the motor being controlled by a probe 11 at the free end of the ramp. To avoid possible continuous raising and lowering of the ram, one or more fluid operated rams 15 controlled by a gravity switch permit continuous small adjustment of the ramp's inclination to be made. The ramp includes load supporting rollers 2 and is normally clear of a quay 12 to permit forks &c. of a truck to be moved below the ramp's end. For loading the ship the ramp is inclined towards the ship. When the ramp is not in use the opening in the ship's side may be closed by doors or covers, not shown. In place of the chains, rotatable threaded screws engaging nuts provided at the ends of the beam 3 may be used. Control by probe 11.-Depending whether vertical movement of the ramp causes a contact 25 or 26 to be engaged by the probe, a valve 20 controlled by solenoids 21, 22 causes the motor 8 to be energized, in the appropriate direction of rotation, via conduits 23 or 24. The contacts 25, 26 also control energization of an electric motor 17 which drives a pump 16. Control by gravity switch 39, 40.-The switch causes a ram 15 to be actuated when the angle which the ramp makes to the horizontal varies. If the angle increases a contact 38 is engaged by the switch arm 40, a motor driven pump 28 is energized and the ram 15 is extended due to fluid pressure via a conduit 31. The ramp is accordingly pivoted upwardly from its hinged end. If the angle of inclination decreases, switch contact 37 is engaged, a solenoid 36 controlling a valve 35 is energized and fluid from the ram is released so that the ramp, by its weight and any load on the ramp, will be pivotally lowered. When loading the ship the contacts 37, 38 are repositioned.

Patent ES-366632-A1 (ES)
Title: Shaped articles
IPC: B29C41/14
Filed: 1969-04-30
Abstract: Water vapour permeable, flexible, microporous three dimensionally shaped shoe uppers or upper components having resistance to loss of shape when heated are made by dip moulding a former into a mixture of a polymer extended in a liquid vehicle, e.g., a solvent, and coagulating the layer of polymer formed upon the former by a non-solvent for the polymer. The uniformity and size of the pores may be enhanced by incorporating removable particles of a filler, e.g., salt, in the extended polymer and removing the filler subsequently by means of the non-solvent, e.g., water, in the case of a salt filler. The non-solvent may contain a dye to be transferred into the dip moulded layer to colour it during the coagulating step. In one embodiment multi-layered polyurethane shoe uppers are made by dipping a hollow sintered polyethylene former into successive salt containing polymer mixtures, the former being covered with a reinforcing sock or toe reinforcement if desired. The former is withdrawn at different speeds to give regions of differing thickness if desired and the non-solvent may be applied by dipping in a bath, passing it into the interior of a hollow porous former, or both. The former may be made of wood, metal, for example wire gauge, solid or sintered plastics, or fabric and is internally supported if necessary. Where hollow, the interior of the former is preferably vented by a tube to the atmosphere to promote adhesion of the material to core.

Title: Data system incorporating method and apparatus for referencing media locations
IPC: G11B15/22
Filed: 1969-10-15
Abstract: Scanning is stopped at a particular location on a tape which is then braked and stopped, and a counter measures the overrun of the tape and controls its back-spacing until this location is once more at the scanning means and then for a predetermined extra distance, preparatory to further forward movement. As shown, the tapedrive sprocket shaft 31 carries, as well as clutch elements (Figs. 2b and 6) and a brake drum (40, Figs. 6 and 7), a disc 9 having slots arranged in three circular tracks R, A, B which are sensed by photo-electric detectors 12 so as to send signals indicative of direction and distance of tape travel to a counter forming part of a logic circuit controlling the tape transport. Information read from the tape is fed to a processor via registers. If these registers become full or the processor detects an error in the information supplied, the tape reading is stopped and braking and back-spacing are initiated. On further forward movement of the tape, reading is resumed when the predetermined extra backspacing distance has been covered.
Patent ES-382913-A1 (ES)
Title: Apparatus for winding strands of thermoplastic material, particularly of glass filaments in the course of their production
IPC: B65H67/048
Filed: 1970-08-20
Abstract: A winding apparatus for newly formed strands of thermoplastic material, constituted by filaments issuing from a plurality of spinning nozzles of a spinneret containing said material in liquid form, such as molten glass, disposed below the latter. Two winding drums on fixed axes extend in parallel to each other in a plane inclined to the horizontal, onto which are adapted to be mounted empty spools, and with which cooperate strand traverse mechanisms which serve to lay up the strands on the spools in crossing relation while the rotary movement of the latter effects a drawing-out of the filaments. The specific disposition of the winding drums permits a convenient transfer of the strands issuing from the spinneret, from the filled bobbins on one drum to the empty bobbins on the other drum without interrupting the drawing-out of the filaments. This transfer may be executed in a non-automatic, semi-automatic, or fully automatic manner. In the last-mentioned case, the completion of a predetermined number of revolutions of the active winding drum, automatically positions an auxiliary rotary winding cage onto the end of the last-mentioned drum by means of a pivotal movement followed by an axial movement of the cage. A deflecting bar shifts the strands from the bobbins being wound on the winding drum onto the winding cage whereat the drawing out of the filaments continues. The rotary cage is then moved axially from the end of the active winding drum, rotated into coaxial position with the heretofore idle winding drum and axially shifted onto the end thereof, without any interruption of the drawing out of the filaments. When the last-mentioned drum reaches its proper rotary speed, the strands are moved back from the winding cage to their winding positions governed by the strand traverse device associated with the last-mentioned drum, for filling up the spools which had been mounted on the last-mentioned drum. The first drum is braked, unloaded and charged with empty spools in readiness for the next transfer of the strands thereto, during the winding operation on the second drum.

Patent ES-419905-A1 (ES)
Title: Method and apparatus for pneumatically conveying discrete amounts of particulate material
IPC: B65G53/06
Filed: 1973-10-24
Abstract: A method for pneumatically conveying incoherent solid materials (e.g. cereals, cement and the like) is disclosed, in which impulsive gas jets (generally air jets), impressed at time intervals to discrete points of a conveying pipeline, cause the material to be advanced stepwise therealong. Valve means are provided for synchronizing the impulsive gas jets with the closing of the pipeline section concerned and with the opening of a gas vent upstream of each gas jet, as well as with the opening of the pipeline and the closing of the gas vent downstream of each gas jet. The gas jets and the valve means thus become operative alternatingly and there are instants of time in which the individual discrete heaps of the material are thrust forward, and others, conversely, in which they are stationary. The invention also provides a system for pneumatically conveying incoherent solid materials, which can be embodied as a plurality of modular units: this fact enables any system made according to this invention to be extended and enlarged as necessity demands, without rebuilding the entire system throughout. Another outstanding advance over the prior art is that pipe sections of a smaller diameter, and higher working pressures can be used, as compared with those heretofore commonly employed by the prior art.
